 ## System Overview
 
-`gruff-php` is a Composer-distributed PHP CLI for opinionated code-quality analysis. The package boundary is `composer.json`: it declares dependencies (`nikic/php-parser`, `symfony/console`, `symfony/finder`, `symfony/process`, `symfony/yaml`), the `bin/gruff-php` entrypoint, the `GruffPhp\` PSR-4 root, and the `check`, `phpstan`, `security:scan`, and `test` Composer scripts. The runtime exposes `analyse`, `summary`, `report`, `dashboard`, `list-rules`, and `init` Symfony Console commands. `analyse` discovers source files, parses PHP through `nikic/php-parser`, runs a deterministic registry of rules, optionally ingests Infection mutation JSON, scores the result, optionally filters to Git diff ranges or compares against a base Git snapshot, and emits a schema-versioned report (`gruff.analysis.v2`) as text, JSON, HTML, Markdown, GitHub annotations, hotspot JSON, or SARIF. `summary` runs the same analyser pipeline and prints the compact `gruff.summary.v1` digest without per-finding output. `report` is the static report convenience command: it delegates to `analyse` and can emit HTML or JSON to stdout or `--output`. `dashboard` is the local interactive server for refreshing scans and pointing gruff-php at other local project roots. `init` writes a default `.gruff-php.yaml` populated from registry defaults, preserving existing path ignores when forced over an existing config.
+**Mission:** gruff-php governs AI-generated code so a human who didn't write it can read, verify, and trust it — capping complexity, requiring intent-bearing doc comments on every method, flagging insecure patterns, and rejecting low-signal test ceremony. The sections below map that intent to the real files that implement it. See `ADR-017` and `docs/mission.md` for the rationale.

+# ADR-017: Project mission — govern AI-generated code for human verifiability
+
+**Status:** Accepted
+**Date:** 2026-05-30
+**Author(s):** Matthew Hansen
+
+## Context
+
+gruff-php began as a general "opinionated PHP code-quality analyzer." In practice its highest-value use is as a gate in a coding agent's loop: the agent writes the code, and a human who did not write it must read, review, and trust it before it ships. Coding agents routinely produce code that superficially works while quietly misunderstanding the requirement, and they pad test suites with low-signal assertions that make a green run meaningless.
+
+Without a stated mission, rule calibration drifts toward "match PHPMD / Sonar defaults" (industry parity) rather than "make this change safe for a human to sign off on." Those two targets disagree: [ADR-010](ADR-010-complexity-and-docs-rubric-default-recalibration.md) anchored the complexity defaults to industry violation/smell lines, but a verifiability lens weights the metrics that track human comprehension differently. This ADR fixes the mission so every downstream rule, default, severity, and documentation decision has a single optimisation target to serve.
+
+## Decision
+
+gruff-php's mission is to **govern AI-generated code so a human can verify, trust, and sign off on it.** Every rule and default is justified by one of three verifiability goals:
+
+1. **Legible enough to verify.** Cap complexity and nesting, and require an intent-bearing doc comment on every method — public or private (see [ADR-004](ADR-004-public-phpdoc-template.md); `docs.missing-public-phpdoc` scans all `ClassMethod` nodes) — that states what the method is for, what it returns at the edges, and what the caller must satisfy. The comment is a plain-English contract the reviewer checks the code against; a doc comment that contradicts the implementation is itself a signal the change needs a deeper look.
+2. **Secure where the eye fails.** The `security` and `sensitive-data` pillars catch the classes of mistake a human reviewer skims past.
+3. **Tested for real, not padded.** The `test-quality` pillar rewards genuine assertions and flags low-signal ceremony, so a green suite means the behaviour is actually exercised rather than mocked into a tautology.
+
+A calibration corollary follows: **a gate earns its place only if the cheapest way for the agent to satisfy it is the genuine improvement, not a cosmetic one.** Cognitive-complexity and nesting (cheapest fix = real simplification) and the test-quality anti-bloat rules (cheapest fix = a real assertion) satisfy this; raw "must have a doc comment" does not unless it demands substance, which is why `docs.missing-public-phpdoc` requires intent rather than presence.
+
+This mission is the lens for calibration. Where industry parity and verifiability disagree, verifiability wins: complexity defaults should favour the metrics that track human comprehension (cognitive, nesting) over branch-counting proxies (cyclomatic, npath) that can misrank a readable guard-chain. ADR-010's specific thresholds remain in force; this ADR records the objective they serve, not new values.
+
+## Failure Mode Comparison
+
+| Option | What fails | Why rejected or accepted |
+| --- | --- | --- |
+| Leave the mission implicit ("code-quality analyzer") | Rule and default decisions optimise for industry parity by default; severity/threshold debates have no shared tie-breaker; the doc-comment-on-everything policy reads as arbitrary strictness. | Rejected. The product already behaves as a verifiability gate; an unstated mission invites drift away from it. |
+| State the mission as "find code smells" | Generic; does not explain why doc comments are mandatory on private one-liners or why test-bloat rules exist. | Rejected. Too weak to constrain calibration. |
+| Govern AI-generated code for human verifiability (legible, secure, honestly tested) | Gives every rule a single justification and a calibration corollary (cheapest fix = genuine fix). | Accepted. |
+
+## Consequences
+
+- The mission is documented for humans in `README.md` (Mission section) and `docs/mission.md` (full rationale), for coding agents in `docs/gruff-cli-agent-instructions.md`, and as the project descriptor in `CLAUDE.md` / `AGENTS.md`. `.goat-flow/architecture.md` carries a one-line Mission lead-in.
+- New rules and default changes must cite which verifiability goal they serve and confirm the cheapest passing fix is the genuine one. A rule whose cheapest fix is cosmetic is a candidate for lower severity, not a hard gate.
+- ADR-010's complexity thresholds are unchanged by this ADR. Revisiting them through the verifiability lens (e.g. treating cognitive and nesting as the primary legibility gates and de-emphasising npath) is a follow-up that would carry its own evidence and an ADR amendment.
+
+## Reversibility
+
+Two-way door. The mission can be narrowed or restated by a superseding ADR; doing so must explain what optimisation target replaces it and how that changes calibration. Until then, "would a human sign this off?" is the tie-breaker for rule, default, and severity decisions.

+# ADR-018: Retire npath and recalibrate the complexity pillar
+
+**Status:** Accepted
+**Date:** 2026-05-30
+**Author(s):** Matthew Hansen
+**Updated:** amends ADR-010
+
+## Context
+
+ADR-010 anchored the complexity defaults to industry violation/smell lines. ADR-017 then fixed the project mission — gruff governs AI-generated code so a human can verify it — and named "de-emphasising npath" as a follow-up. `complexity.npath` measures the multiplicative count of independent execution paths, so it explodes on sequential-but-simple branching: its *unique* findings are false positives (genuinely hard-to-verify code is already caught by `complexity.cognitive` and `complexity.nesting-depth`; test-surface by `complexity.cyclomatic`), and its cheapest fix is cosmetic. `src/Scoring/CompositeFindingFactory.php` already excluded `halstead-volume` and `maintainability-index` from the `design.god-method` complexity trigger, treating cognitive/cyclomatic/nesting/npath as the "real" complexity signals; this decision completes that direction.
+
+## Decision
+
+Retire `complexity.npath` entirely (breaking; rule-id removal, precedent ADR-014) and recalibrate the remaining complexity rules to the mission:
+
+| Rule | Before | After |
+| --- | --- | --- |
+| `complexity.npath` | error @ 200 | **removed** |
+| `complexity.halstead-volume` | error @ 8000 | **advisory** @ 8000 |
+| `complexity.maintainability-index` | error @ 35 | **advisory** @ 35 |

+
+Registry: 119 → 118 rules; complexity pillar 5 → 4. The `halstead-volume` and `maintainability-index` *computations* are retained (MI still consumes Halstead); only their severity changes. `design.god-method`'s complexity trigger becomes `{cognitive, cyclomatic, nesting}`.
+
+End state: `cognitive` (error, 20) + `nesting` (error, 4) are the legibility hard-gates; `cyclomatic` (warning, 20) is a secondary signal that misranks legibility; `halstead-volume` + `maintainability-index` (advisory) are informational.
+
+## Failure Mode Comparison
+
+| Option | What fails | Verdict |
+| --- | --- | --- |
+| Keep npath at error | Forces cosmetic refactors on readable sequential branching; its cheapest fix is not the genuine improvement (ADR-017 corollary). | Rejected. |
+| Demote npath to advisory instead of deleting | Keeps an opaque metric the author judged redundant with the trio. | Rejected for npath (it actively misleads); chosen for halstead/MI (opaque but not misleading). |
+| Delete halstead + MI too | Sharper, but a further breaking change with no extra mission benefit now. | Deferred (documented stretch goal). |
+
+## Consequences
+
+- Breaking: a config block referencing `complexity.npath` now fails closed (unknown rule id → `ConfigException`); the CHANGELOG instructs users to remove it and regenerate baselines.
+- Rule-count stamps move 119 → 118 (and complexity 5 → 4) across `README.md`, `.goat-flow/architecture.md`, `.goat-flow/code-map.md`, `docs/rules.md`, `composer.json`.
+- Tightening `cognitive`→20 surfaces previously-passing dense methods; these are resolved or baselined, never silently suppressed.
+- The config validator now accepts `severity: advisory` (previously only `warning`/`error`), since `halstead-volume` and `maintainability-index` default to advisory and `init` scaffolds each rule's default severity — without this, `gruff-php init` would emit a config the loader rejects.
+
+## Reversibility
+
+Two-way door for the severity recalibrations (advisory/warning are config-overridable). npath's removal is a one-way-ish breaking change, reversible only by re-adding the rule id in a future release. Rollback path: restore each rule's prior `SeverityThreshold` and re-register `NpathComplexityRule`.

+- **Changed-region analysis** - `analyse` now accepts `--changed-ranges`, `--since`, bare `--diff`, `--diff -`, and `--changed-scope=symbol|hunk` so hook consumers can request only findings attributable to the edited region. JSON reports include `suppressedCount` when this mode filters out pre-existing findings.
+- **BREAKING: Retired the `complexity.npath` rule** - NPath produced false positives on sequential-but-simple branching and is redundant with the cognitive, cyclomatic, and nesting metrics. Remove any `complexity.npath` block from your config (it now fails closed as an unknown rule id) and regenerate baselines to drop stale npath findings. The registry now exposes 118 rules.
+- **Complexity recalibration** - `complexity.halstead-volume` and `complexity.maintainability-index` are now `advisory` (informational, non-gating); `complexity.cognitive` tightened to a threshold of 20 and `complexity.nesting-depth` to 4; `complexity.cyclomatic` is now `warning`. The complexity pillar now gates on the metrics that track human comprehension rather than branch-counting proxies.
+- **Config accepts `advisory` severity** - the `rules.<id>.severity` config key now accepts `advisory` alongside `warning` and `error`, so rules that default to advisory can be pinned or overridden in `.gruff-php.yaml`.

 gruff-php 0.2.0 tightens the CI gating philosophy, requires explicit config-schema versioning, and adds a per-rule triage surface so large scans stop being overwhelming. Five breaking changes (`schemaVersion:` required, `analyse` default lowered, JSON schemas v2, one rule retired, `waste.one-line-method` defaults tightened) motivate the minor bump from 0.1.x; each ships with a migration path below.

 `gruff-php` is an opinionated PHP code-quality analyzer. It scans PHP projects, scores findings across quality pillars, and emits reports for terminals, CI annotations, SARIF consumers, static HTML, and a local dashboard. It is heuristic static analysis; run it beside PHPStan, Psalm, PHPUnit, PHP-CS-Fixer, PHPCS, security scanners, and code review, not instead of them.
 
+## Mission
+
+gruff-php exists to make AI-generated code safe for a human to sign off on. When a coding agent writes the code, someone who didn't write it still has to read, review, and trust it — and agents routinely produce code that superficially works while quietly misunderstanding the requirement. gruff governs that code so a reviewer can actually verify it does what was asked:
+
+- **Legible enough to verify.** Complexity and nesting are capped, and every method — public or private — must carry an intent-bearing doc comment that states what it is for, what it returns at the edges, and what the caller must satisfy. The comment gives the reviewer a plain-English contract to check the code against; a doc comment that contradicts the implementation is a signal the change needs a deeper look.
+- **Secure where the eye fails.** Security and sensitive-data rules catch the classes of mistake a human reviewer skims past.
+- **Tested for real, not padded.** Test-quality rules reward genuine assertions and flag low-signal ceremony, so a green suite means the behaviour is actually exercised rather than mocked into a tautology.
+
+Wired into a coding agent's loop — as a pre-commit hook, a CI gate (`--fail-on`), or the agent's own verification step — gruff pushes the agent to keep producing code a human can confidently approve, not just code that compiles and passes. See [`docs/mission.md`](docs/mission.md) for the full rationale.

+## What gruff optimises for
+
+You are a coding agent, and a human who didn't write this code has to read, review, and trust it. gruff governs the code you produce so that reviewer can verify it does what was asked — legible enough to read, secure where the eye fails, and tested for real rather than padded with low-signal ceremony. Treat its findings as a checklist for "would a human sign this off?", not as arbitrary style nags.
+
+Doc comments are mandatory even on a private one-liner, and that is deliberate. Coding agents routinely produce code that superficially works while misunderstanding the requirement; stating intent, usage, contract, and failure behaviour in prose gives the reviewer something to check the implementation against. A mismatch between the doc comment and the code is itself a signal the change needs a deeper look — so write the intent, never a restatement of the signature.

+# gruff-php Mission
+
+> gruff-php exists to make AI-generated code safe for a human to sign off on.
+
+## The problem
+
+When a coding agent writes the code, someone who didn't write it still has to read, review, and trust it before it ships. Two failure modes dominate AI-generated changes:
+
+- The code **superficially works while misunderstanding the requirement** — it compiles, it passes a happy-path test, but it does the wrong thing in a way a quick skim won't catch.
+- The tests are **padded with low-signal ceremony** — mocks with no expectations, assertions that restate a literal, snapshots of nothing — so a green run no longer means the behaviour is exercised.
+
+A reviewer cannot catch either of these by reading faster. gruff governs the code so the reviewer has something concrete to check against.
+
+## What gruff optimises for
+
+Every rule and default earns its place by serving one of three verifiability goals:
+
+1. **Legible enough to verify.** Complexity and nesting are capped so a method fits in a reviewer's head, and every method — public or private — must carry an intent-bearing doc comment stating what it is for, what it returns at the edges, and what the caller must satisfy. The comment is a plain-English contract the reviewer checks the implementation against. A doc comment that contradicts the code is a signal the change needs a deeper look — not noise.
+2. **Secure where the eye fails.** The `security` and `sensitive-data` pillars catch the classes of mistake a human reviewer skims past: injection, unsafe deserialization, leaked secrets, weak crypto, and similar.
+3. **Tested for real, not padded.** The `test-quality` pillar rewards genuine assertions and flags low-signal ceremony, so a green suite means the behaviour is actually exercised rather than mocked into a tautology.
+
+## The calibration principle
+
+A gate earns its place only if **the cheapest way for the agent to satisfy it is the genuine improvement, not a cosmetic one.**
+
+- Cognitive complexity and nesting pass this test: the cheapest fix is real simplification (guard clauses, a named sub-step), which is exactly what makes the code more verifiable.
+- The test-quality anti-bloat rules pass it: the cheapest fix is a real assertion.
+- "Must have a doc comment" passes it **only if it demands substance** — which is why `docs.missing-public-phpdoc` asks for intent, not a restatement of the signature. A rule whose cheapest passing fix is cosmetic is a candidate for lower severity, not a hard gate.
+
+This is also why gruff favours metrics that track human comprehension (cognitive complexity, nesting depth) over pure branch-counting proxies, which can flag a flat, readable guard-chain while waving through genuinely tangled control flow.
+
+## Why doc comments are mandatory, even on a private one-liner
+
+`docs.missing-public-phpdoc` requires a local doc comment on every method declaration — public, protected, private, abstract, accessor, magic, helper, or interface implementation (the historical rule ID predates this scope; do not infer "public only" from the name).
+
+That is deliberate. Forcing the agent to state intent, usage, contract, and failure behaviour in prose gives the reviewer an independent description to check the implementation against. When the prose and the code disagree, the reviewer has found either a bug or a misunderstanding — which is the whole point. The rule wants content, not boilerplate: a comment that merely restates the signature adds no verifiability and is itself flagged.
+
+## How gruff is used
+
+gruff is a CLI that emits findings and an exit code (`--fail-on none|advisory|warning|error`). Wired into a coding agent's loop it becomes a gate:
+
+- as a **pre-commit hook**, so the agent cannot stage code that fails the bar;
+- as a **CI check** (`--format github` / `--format sarif`), so a reviewer sees findings inline; or
+- as the **agent's own verification step**, so it iterates until the change is something a human can approve.
+
+Because the cheapest way to clear the gate is the genuine fix, the agent is pushed toward producing verifiable code rather than learning to game the metric.
+
+## What gruff is not
+
+gruff is heuristic static analysis, not a proof. It does not format code, run your tests, or replace type-aware analysis. Run it **beside** PHPStan, Psalm, PHPUnit, PHP-CS-Fixer/PHPCS, security scanners, and human code review — not instead of them.

-## Unreleased
+## 1.0.0 - 2026-05-30
+
+First stable release. gruff-php sharpens around a single mission — governing AI-generated code so a human who didn't write it can read, verify, and trust it — and commits to a stable rule and schema surface. The headline breaking change retires the noisy `complexity.npath` rule and recalibrates the complexity pillar toward the metrics that track human comprehension; changed-region analysis lands so coding-agent hooks can gate only the lines they touched.
 
 - **Changed-region analysis** - `analyse` now accepts `--changed-ranges`, `--since`, bare `--diff`, `--diff -`, and `--changed-scope=symbol|hunk` so hook consumers can request only findings attributable to the edited region. JSON reports include `suppressedCount` when this mode filters out pre-existing findings.
 - **BREAKING: Retired the `complexity.npath` rule** - NPath produced false positives on sequential-but-simple branching and is redundant with the cognitive, cyclomatic, and nesting metrics. Remove any `complexity.npath` block from your config (it now fails closed as an unknown rule id) and regenerate baselines to drop stale npath findings. The registry now exposes 118 rules.
 - **Complexity recalibration** - `complexity.halstead-volume` and `complexity.maintainability-index` are now `advisory` (informational, non-gating); `complexity.cognitive` tightened to a threshold of 20 and `complexity.nesting-depth` to 4; `complexity.cyclomatic` is now `warning`. The complexity pillar now gates on the metrics that track human comprehension rather than branch-counting proxies.
 - **Config accepts `advisory` severity** - the `rules.<id>.severity` config key now accepts `advisory` alongside `warning` and `error`, so rules that default to advisory can be pinned or overridden in `.gruff-php.yaml`.
+- **Mission documented** - a stated project mission (governing AI-generated code for human verifiability) now anchors `README.md`, `docs/mission.md`, and the agent instructions, recorded in ADR-017.

+# ADR-019 - `paths.ignore` authoritative everywhere, with a shared ignore engine and `check-ignore`
+
+- Status: Accepted
+- Date: 2026-05-30
+- Relates to: ADR-017 (mission: govern AI-generated code so a human can sign off)
+
+## Context
+
+gruff runs as a coding-agent hook: after an agent edits files, the hook runs gruff
+on the changed paths and gates on the result. A project's `paths.ignore` records
+code the team has deliberately put out of scope. If the hook surfaced findings for
+those paths, the agent would waste loops "fixing" code no human wants reviewed.
+
+Empirically (verified on a throwaway project ignoring `legacy/**`, 2026-05-30),
+gruff-php **already** applies `paths.ignore` in every invocation shape — explicit
+file args, whole-tree, `--changed-ranges`, `--diff` working-tree, `--diff -` stdin,
+and `--include-ignored` — because every mode routes file selection through
+`SourceDiscovery`, which checks the configured patterns unconditionally. An ignored
+path yields zero findings and appears in the report's `ignoredPaths`.
+
+Two gaps remain, both relevant to the hook use case:
+
+1. **No reason.** `ignoredPaths` is a bare list of strings. A hook (or a human)
+   cannot tell *why* a path was skipped — a config glob, a built-in default, a
+   generated lockfile, or `.gitignore` — nor which pattern matched.
+2. **No way to ask without analysing.** There is no command to answer "would gruff
+   ignore this path?" cheaply, and the ignore logic lives in private methods inside
+   `SourceDiscovery`, so any new consumer would have to duplicate the glob/default
+   matching — inviting drift from the behaviour `analyse` actually uses.
+
+## Decision
+
+1. **One ignore engine.** Extract the ignore decision into a single reusable
+   resolver that owns the configured-glob match, the built-in default directories,
+   the generated-file (lockfile) match, and the `.gitignore` lookup. `SourceDiscovery`
+   delegates to it; the new command uses the same resolver. There is exactly one
+   implementation of the ignore decision.
+
+2. **Report the reason, additively.** Keep the existing `ignoredPaths` string list
+   byte-identical for backward compatibility, and add a parallel
+   `ignoredPathDetails` field whose entries carry `path`, `source`, and `pattern`.
+   This is an additive change within the existing `gruff.analysis.v2` schema — no
+   rename, per the cross-language compatibility policy — documented as a migration
+   note in the schema/output docs.
+
+3. **Source taxonomy.** `source` is one of `config` (a `paths.ignore` glob — `pattern`
+   is that glob), `default` (a built-in ignored directory such as `vendor` — `pattern`
+   is the directory token), `generated` (a built-in generated/lock filename such as
+   `composer.lock` — `pattern` is the filename), or `gitignore` (excluded by git —
+   `pattern` is the matching `.gitignore` rule when git reports it, else null).
+
+4. **`--include-ignored` never overrides `paths.ignore`.** It opts back into
+   git-ignored and default/generated paths only. Configured `paths.ignore` stays
+   authoritative under it (already true; now locked by tests).
+
+5. **`check-ignore` command.** Add `check-ignore [--format text|json]
+   [--config <path>|--no-config] <path>...` that answers the ignore decision per
+   path using the shared engine and resolution, performs no analysis (O(1) per
+   path), and mirrors `git check-ignore` exit codes (0 = at least one ignored,
+   1 = none, 2 = error). JSON `[{path, ignored, source, pattern}]` is the agent
+   contract; verbose text prints `<path>\t<source>:<pattern>`.
+
+## Consequences
+
+- A hook can pre-flight `check-ignore` (or read `ignoredPathDetails`) to drop
+  out-of-scope changed files before it even calls `analyse`, and can explain to the
+  agent *why* a path is skipped.
+- `analyse` and `check-ignore` can never disagree about what is ignored: they share
+  one engine. Adding a built-in ignore or changing glob semantics changes both at
+  once.
+- Existing JSON/SARIF/text consumers keep working unchanged; `ignoredPathDetails`
+  is purely additive and the schema string is unchanged.
+- The cross-language `CONTRACT.md` gains a `check-ignore` command and an
+  authoritative-`paths.ignore` clause so the guarantee is consistent across ports.

 First stable release. gruff-php sharpens around a single mission — governing AI-generated code so a human who didn't write it can read, verify, and trust it — and commits to a stable rule and schema surface. The headline breaking change retires the noisy `complexity.npath` rule and recalibrates the complexity pillar toward the metrics that track human comprehension; changed-region analysis lands so coding-agent hooks can gate only the lines they touched.
 
 - **Changed-region analysis** - `analyse` now accepts `--changed-ranges`, `--since`, bare `--diff`, `--diff -`, and `--changed-scope=symbol|hunk` so hook consumers can request only findings attributable to the edited region. JSON reports include `suppressedCount` when this mode filters out pre-existing findings.
+- **Ignore reasons and `check-ignore`** - the JSON report's new additive `ignoredPathDetails` field records why each path was excluded — its `source` (`config`, `default`, `generated`, or `gitignore`) and matching `pattern` — alongside the existing `ignoredPaths` list. A new `check-ignore [--format text|json] [--config <path>|--no-config] <path>...` command answers whether gruff would ignore a path, and why, without running an analysis (JSON `[{path, ignored, source, pattern}]`; exit codes mirror `git check-ignore`). `paths.ignore` stays authoritative in every mode — explicit file operands and all diff/changed-region scans, not just the directory walk — and `--include-ignored` never overrides it.
 - **BREAKING: Retired the `complexity.npath` rule** - NPath produced false positives on sequential-but-simple branching and is redundant with the cognitive, cyclomatic, and nesting metrics. Remove any `complexity.npath` block from your config (it now fails closed as an unknown rule id) and regenerate baselines to drop stale npath findings. The registry now exposes 118 rules.
 - **Complexity recalibration** - `complexity.halstead-volume` and `complexity.maintainability-index` are now `advisory` (informational, non-gating); `complexity.cognitive` tightened to a threshold of 20 and `complexity.nesting-depth` to 4; `complexity.cyclomatic` is now `warning`. The complexity pillar now gates on the metrics that track human comprehension rather than branch-counting proxies.
 - **Config accepts `advisory` severity** - the `rules.<id>.severity` config key now accepts `advisory` alongside `warning` and `error`, so rules that default to advisory can be pinned or overridden in `.gruff-php.yaml`.

+
+`paths.ignore` is authoritative in every mode — including diff and explicit-path
+scans, the shapes a coding-agent hook uses. A matching path is excluded from
+analysis and produces no findings, so a hook that passes the agent's changed
+files never surfaces findings for code the project deliberately excluded.
+`--include-ignored` opts back into Git/default ignores only; it never overrides
+`paths.ignore`.
+
+Ask whether gruff would ignore a path — and why — without running an analysis,
+using `check-ignore`:
+
+```sh
+vendor/bin/gruff-php check-ignore --format json src/App.php legacy/Old.php
+```
+
+```json

+  { "path": "src/App.php", "ignored": false, "source": null, "pattern": null },
+  { "path": "legacy/Old.php", "ignored": true, "source": "config", "pattern": "legacy/**" }
+]
+```
+
+Exit codes mirror `git check-ignore`: `0` when at least one path is ignored, `1`
+when none are, `2` on error. A hook can use this to drop out-of-scope changed
+files before it calls `analyse`.

Subject: [PATCH 04/25] Add baseline movement reporting and failure conditions
 count gate

- Implement three-state baseline reporting that classifies findings into new, unchanged, and resolved buckets, enhancing JSON output and summary views.
- Introduce a `--baseline-include-absent` flag to list resolved entries in text, markdown, and HTML outputs.
- Add support for per-severity count gates through a new `failureConditions` configuration block, allowing teams to set thresholds for findings.
- Update reports to include failure reasons when thresholds are exceeded, improving clarity in CI logs.

+First stable release. gruff-php sharpens around a single mission — governing AI-generated code so a human who didn't write it can read, verify, and trust it — and commits to a stable rule and schema surface. The headline breaking change retires the noisy `complexity.npath` rule and recalibrates the complexity pillar toward the metrics that track human comprehension; changed-region analysis lands — and `paths.ignore` becomes authoritative across every scan mode — so coding-agent hooks gate only the lines they touched and never the code the project deliberately excluded.
 
 - **Changed-region analysis** - `analyse` now accepts `--changed-ranges`, `--since`, bare `--diff`, `--diff -`, and `--changed-scope=symbol|hunk` so hook consumers can request only findings attributable to the edited region. JSON reports include `suppressedCount` when this mode filters out pre-existing findings.
-- **Ignore reasons and `check-ignore`** - the JSON report's new additive `ignoredPathDetails` field records why each path was excluded — its `source` (`config`, `default`, `generated`, or `gitignore`) and matching `pattern` — alongside the existing `ignoredPaths` list. A new `check-ignore [--format text|json] [--config <path>|--no-config] <path>...` command answers whether gruff would ignore a path, and why, without running an analysis (JSON `[{path, ignored, source, pattern}]`; exit codes mirror `git check-ignore`). `paths.ignore` stays authoritative in every mode — explicit file operands and all diff/changed-region scans, not just the directory walk — and `--include-ignored` never overrides it.
+- **Ignore reasons and `check-ignore`** - the JSON report's new additive `ignoredPathDetails` field records why each path was excluded — its `source` (`config`, `default`, `generated`, or `gitignore`) and matching `pattern` — alongside the existing `ignoredPaths` list.

+- **Three-state baseline reporting** - applying a baseline now classifies findings into `new` / `unchanged` / `resolved` buckets — exposed in JSON at `baseline.buckets` and as a one-line "Movement: N new, M unchanged, K resolved" summary in text, markdown, and HTML — turning the baseline from a write-only mute list into a debt-movement view. A new `--baseline-include-absent` flag lists the resolved (absent) entries in text/markdown/HTML output (off by default to keep PR comments short). The on-disk `gruff-baseline.json` and `gruff.baseline.v1` schema are unchanged.
+- **Per-severity count gates** - a new `failureConditions:` config block expresses the gate as counts — `total: <int>` and `severityThresholds: {advisory, warning, error}: <int>` — so a team can "allow up to 5 warnings, fail on any error" without committing a baseline ("allow N" passes at count ≤ N, fails above). A tripped gate prints a one-line `Failed: …` reason in text and markdown and a top-level `failureReason` (`{thresholdKind, count, cap, message}`) in JSON, so CI logs explain which threshold was exceeded. `--fail-on <severity>` is unchanged and still wins when passed explicitly; with no `failureConditions:` block the gate behaves exactly as before, and baselined findings remain excluded from the count.
 - **BREAKING: Retired the `complexity.npath` rule** - NPath produced false positives on sequential-but-simple branching and is redundant with the cognitive, cyclomatic, and nesting metrics. Remove any `complexity.npath` block from your config (it now fails closed as an unknown rule id) and regenerate baselines to drop stale npath findings. The registry now exposes 118 rules.
 - **Complexity recalibration** - `complexity.halstead-volume` and `complexity.maintainability-index` are now `advisory` (informational, non-gating); `complexity.cognitive` tightened to a threshold of 20 and `complexity.nesting-depth` to 4; `complexity.cyclomatic` is now `warning`. The complexity pillar now gates on the metrics that track human comprehension rather than branch-counting proxies.
 - **Config accepts `advisory` severity** - the `rules.<id>.severity` config key now accepts `advisory` alongside `warning` and `error`, so rules that default to advisory can be pinned or overridden in `.gruff-php.yaml`.

+## Failure Conditions (count gate)
+
+`--fail-on <severity>` is a binary gate. For a count-based policy — "allow N findings at a severity, fail above" — set `failureConditions:` in `.gruff-php.yaml`:
+
+```yaml
+failureConditions:
+  total: 200
+  severityThresholds:
+    error: 0
+    warning: 5
+    advisory: 50
+```
+
+"allow N" means the run passes at count ≤ N and fails at count > N; `error: 0` is the legacy "fail on any error". Any threshold that trips — a severity cap or the `total` cap — fails the run. An explicit `--fail-on` flag overrides `failureConditions`; with neither set, the gate is unchanged from before. When the gate trips, the JSON report carries a top-level `failureReason` (`{thresholdKind, count, cap, message}`) and text/markdown print a one-line `Failed: …`, so CI logs explain *why* without a re-run. Baselined findings are excluded from the count (the gate sees the post-baseline set).

 ## Current Gaps to Avoid Assuming
 
 - `--diff=<base>` is a changed-line/file filter, not a full base/current subtraction engine.

+First stable release. gruff-php sharpens around a single mission — governing AI-generated code so a human who didn't write it can read, verify, and trust it — and commits to a stable rule and schema surface. The headline breaking change retires the noisy `complexity.npath` rule and recalibrates the complexity pillar toward the metrics that track human comprehension; changed-region analysis lands — and `paths.ignore` becomes authoritative across every scan mode — so coding-agent hooks see only the lines they touched and never the code the project deliberately excluded. A baseline-aware gate chain (three-state baseline reporting, per-severity count thresholds, and the `--fail-on-new` capstone) completes that workflow: CI can fail only on the debt a change introduces, freezing existing debt as visible-but-non-blocking.
 
 - **Changed-region analysis** - `analyse` now accepts `--changed-ranges`, `--since`, bare `--diff`, `--diff -`, and `--changed-scope=symbol|hunk` so hook consumers can request only findings attributable to the edited region. JSON reports include `suppressedCount` when this mode filters out pre-existing findings.
 - **Ignore reasons and `check-ignore`** - the JSON report's new additive `ignoredPathDetails` field records why each path was excluded — its `source` (`config`, `default`, `generated`, or `gitignore`) and matching `pattern` — alongside the existing `ignoredPaths` list. A new `check-ignore [--format text|json] [--config <path>|--no-config] <path>...` command answers whether gruff would ignore a path, and why, without running an analysis (JSON `[{path, ignored, source, pattern}]`; exit codes mirror `git check-ignore`). `paths.ignore` stays authoritative in every mode — explicit file operands and all diff/changed-region scans, not just the directory walk — and `--include-ignored` never overrides it (ADR-019).
 - **Three-state baseline reporting** - applying a baseline now classifies findings into `new` / `unchanged` / `resolved` buckets — exposed in JSON at `baseline.buckets` and as a one-line "Movement: N new, M unchanged, K resolved" summary in text, markdown, and HTML — turning the baseline from a write-only mute list into a debt-movement view. A new `--baseline-include-absent` flag lists the resolved (absent) entries in text/markdown/HTML output (off by default to keep PR comments short). The on-disk `gruff-baseline.json` and `gruff.baseline.v1` schema are unchanged.
 - **Per-severity count gates** - a new `failureConditions:` config block expresses the gate as counts — `total: <int>` and `severityThresholds: {advisory, warning, error}: <int>` — so a team can "allow up to 5 warnings, fail on any error" without committing a baseline ("allow N" passes at count ≤ N, fails above). A tripped gate prints a one-line `Failed: …` reason in text and markdown and a top-level `failureReason` (`{thresholdKind, count, cap, message}`) in JSON, so CI logs explain which threshold was exceeded. `--fail-on <severity>` is unchanged and still wins when passed explicitly; with no `failureConditions:` block the gate behaves exactly as before, and baselined findings remain excluded from the count.
+- **New-findings-only gate (`--fail-on-new`)** - the capstone of the coding-agent-hook workflow: fail CI only on findings the change *introduced*, freezing pre-existing debt as visible-but-non-blocking. `--fail-on-new` (shorthand for `failureConditions.newFindings.severityThresholds.error: 0`, which also accepts `severityThresholds`/`total`) gates the new set, defined as `baselineNew ∩ branchIntroduced` — the post-baseline findings when `--baseline` is set, the branch-introduced findings when `--diff-vs <ref>` is set, their intersection when both are; never "all findings". Enabling it with no reference point (no baseline and no `--diff-vs`) fails fast at setup instead of failing every finding. A new-findings trip renders distinctly (`Failed: 3 new error finding(s)…`, JSON `failureReason.scope: "new"` plus a `newFindingsCount`); the total gate and the new-findings gate fire independently, with the new-findings reason winning when both trip.
 - **BREAKING: Retired the `complexity.npath` rule** - NPath produced false positives on sequential-but-simple branching and is redundant with the cognitive, cyclomatic, and nesting metrics. Remove any `complexity.npath` block from your config (it now fails closed as an unknown rule id) and regenerate baselines to drop stale npath findings. The registry now exposes 118 rules.
 - **Complexity recalibration** - `complexity.halstead-volume` and `complexity.maintainability-index` are now `advisory` (informational, non-gating); `complexity.cognitive` tightened to a threshold of 20 and `complexity.nesting-depth` to 4; `complexity.cyclomatic` is now `warning`. The complexity pillar now gates on the metrics that track human comprehension rather than branch-counting proxies.
 - **Config accepts `advisory` severity** - the `rules.<id>.severity` config key now accepts `advisory` alongside `warning` and `error`, so rules that default to advisory can be pinned or overridden in `.gruff-php.yaml`.

 "allow N" means the run passes at count ≤ N and fails at count > N; `error: 0` is the legacy "fail on any error". Any threshold that trips — a severity cap or the `total` cap — fails the run. An explicit `--fail-on` flag overrides `failureConditions`; with neither set, the gate is unchanged from before. When the gate trips, the JSON report carries a top-level `failureReason` (`{thresholdKind, count, cap, message}`) and text/markdown print a one-line `Failed: …`, so CI logs explain *why* without a re-run. Baselined findings are excluded from the count (the gate sees the post-baseline set).
 
+## New-findings-only gate (`--fail-on-new`)
+
+The highest-value hook policy: fail only on the debt a change *introduces*, leaving pre-existing findings visible but non-blocking. Provide a reference point — a committed baseline or a `--diff-vs` ref — and enable the gate:
+
+```bash
+# Against a committed baseline (existing debt frozen in gruff-baseline.json):
+php bin/gruff-php analyse src --baseline --fail-on-new
+
+# Against a base ref, no baseline file (PR-check style):
+php bin/gruff-php analyse src --diff-vs origin/main --fail-on-new
+```
+
+`--fail-on-new` is shorthand for `failureConditions.newFindings.severityThresholds.error: 0`; the YAML form takes the same `severityThresholds`/`total` shape as the total gate:
+
+```yaml
+failureConditions:
+  severityThresholds: { error: 0 }     # total gate (all findings)
+  newFindings:
+    severityThresholds: { error: 0 }   # new-findings gate
+```
+
+"New" is `baselineNew ∩ branchIntroduced`: the post-baseline set with `--baseline`, the branch-introduced set with `--diff-vs`, their intersection with both — never "all findings". The total gate and the new-findings gate are independent (either can fail the run); the new-findings reason wins when both trip and renders as `Failed: N new <severity> finding(s)…` with JSON `failureReason.scope: "new"` and a top-level `newFindingsCount`. Enabling the gate with no reference point (no baseline and no `--diff-vs`) errors at setup rather than treating every finding as new.
+
 ## Current Gaps to Avoid Assuming
 
 - `--diff=<base>` is a changed-line/file filter, not a full base/current subtraction engine.

+# ADR-020 - Incremental per-file result cache
+
+- Status: Accepted
+- Date: 2026-05-30
+- Relates to: ADR-017 (mission: govern AI-generated code; fast hook feedback keeps the agent loop tight)
+
+## Context
+
+Every `gruff-php analyse` invocation is a cold start: it re-parses and re-runs all
+per-unit rules from scratch. The in-process caches (`NodeIndex`, complexity
+memoization) live and die with the process, so a hook that spawns a fresh process
+per run, or CI that re-scans an unchanged tree, pays full price each time. We want a
+warm, cross-run cache — **without ever trading correctness for speed** (a stale
+cached finding misleads the reviewer, the cardinal sin).
+
+A material design constraint surfaced during implementation: **per-file caching is
+only byte-identical-correct when no project rule is enabled.** Project rules
+(`ProjectRuleInterface`, including streaming `ProjectRuleAccumulator`s such as the
+design / dead-code rules) observe *every* analysis unit; reusing one file's cached
+findings while skipping its analysis would corrupt their cross-file output. Only
+3 rules are project rules, so configs that exclude them (e.g. the `security`
+profile, or a fast per-file hook config) are fully cacheable.
+
+## Decision
+
+1. **Content-addressed key.** Per-file key = `sha256(runDigest + displayPath +
+   sha256(fileBytes))`, where `runDigest = sha256(gruff version + minimumPhpVersion
+   + sorted allowlists + the enabled-rule set with each rule's resolved settings)`.
+   Any change to what gruff checks, how, on which bytes, or at which path → a new
+   key → a guaranteed miss. The display path is in the key because it is part of
+   every finding's identity, so two identical files at different paths never share
+   an entry. The digest is a conservative superset: it only ever invalidates more.
+
+2. **Guarded to no-project-rule runs.** The cache engages only when
+   `!hasEnabledProjectRules` (and `!--no-cache`). With any project rule active the
+   cache is bypassed — correct, just uncached. Files with parse errors are never
+   cached (so their diagnostics are always reproduced).
+
+3. **Fail open, never stale.** A missing, unreadable, or corrupt entry, or any
+   encode failure, is treated as a miss. With `--no-cache` or a cold cache, output
+   is byte-identical to before — proven by a cold-vs-warm equivalence test over a
+   real, metadata-bearing finding.
+
+4. **Bounded and private.** Entries live under a gitignored, discovery-ignored
+   `.gruff-cache/` directory, capped with oldest-first eviction. The store holds
+   only the findings a run produced (sensitive-data findings are already redacted),
+   never raw source.
+
+5. **Snapshot cache deferred.** Caching the `--diff-vs` base-ref `GitArchiveSnapshot`
+   by commit SHA is valuable but has a path-limiting subtlety (snapshots are
+   archived per requested path set, not whole-tree), so it is left to a focused
+   follow-up rather than bundled here.
+
+## Consequences
+
+- Cache-eligible runs (no project rules) re-use unchanged files' findings across
+  runs; the headline win is repeated whole-set scans where most files are stable.
+- `analyse` and the cache can never disagree: the key folds in every input to a
+  per-unit rule, and the equivalence test is the standing proof.
+- Correctness is preserved unconditionally — the guard plus the fail-open contract
+  mean the cache can only ever make a correct run faster, never change its result.

 - **Three-state baseline reporting** - applying a baseline now classifies findings into `new` / `unchanged` / `resolved` buckets — exposed in JSON at `baseline.buckets` and as a one-line "Movement: N new, M unchanged, K resolved" summary in text, markdown, and HTML — turning the baseline from a write-only mute list into a debt-movement view. A new `--baseline-include-absent` flag lists the resolved (absent) entries in text/markdown/HTML output (off by default to keep PR comments short). The on-disk `gruff-baseline.json` and `gruff.baseline.v1` schema are unchanged.
 - **Per-severity count gates** - a new `failureConditions:` config block expresses the gate as counts — `total: <int>` and `severityThresholds: {advisory, warning, error}: <int>` — so a team can "allow up to 5 warnings, fail on any error" without committing a baseline ("allow N" passes at count ≤ N, fails above). A tripped gate prints a one-line `Failed: …` reason in text and markdown and a top-level `failureReason` (`{thresholdKind, count, cap, message}`) in JSON, so CI logs explain which threshold was exceeded. `--fail-on <severity>` is unchanged and still wins when passed explicitly; with no `failureConditions:` block the gate behaves exactly as before, and baselined findings remain excluded from the count.
 - **New-findings-only gate (`--fail-on-new`)** - the capstone of the coding-agent-hook workflow: fail CI only on findings the change *introduced*, freezing pre-existing debt as visible-but-non-blocking. `--fail-on-new` (shorthand for `failureConditions.newFindings.severityThresholds.error: 0`, which also accepts `severityThresholds`/`total`) gates the new set, defined as `baselineNew ∩ branchIntroduced` — the post-baseline findings when `--baseline` is set, the branch-introduced findings when `--diff-vs <ref>` is set, their intersection when both are; never "all findings". Enabling it with no reference point (no baseline and no `--diff-vs`) fails fast at setup instead of failing every finding. A new-findings trip renders distinctly (`Failed: 3 new error finding(s)…`, JSON `failureReason.scope: "new"` plus a `newFindingsCount`); the total gate and the new-findings gate fire independently, with the new-findings reason winning when both trip.
+- **Incremental result cache** - cache-eligible runs (those with no project rules — e.g. the `security` profile, or a config that excludes the design/dead-code rules) now reuse unchanged files' findings across runs via a content-addressed, gitignored `.gruff-cache/`, keyed on file bytes plus the resolved rule settings plus the gruff version. A cold cache and `--no-cache` produce byte-identical output; any content, config, or version change invalidates the affected entries; runs with project rules bypass the cache entirely (their cross-file rules need every unit). The base-ref snapshot cache for `--diff-vs` is a documented follow-up (ADR-020).
 - **BREAKING: Retired the `complexity.npath` rule** - NPath produced false positives on sequential-but-simple branching and is redundant with the cognitive, cyclomatic, and nesting metrics. Remove any `complexity.npath` block from your config (it now fails closed as an unknown rule id) and regenerate baselines to drop stale npath findings. The registry now exposes 118 rules.
 - **Complexity recalibration** - `complexity.halstead-volume` and `complexity.maintainability-index` are now `advisory` (informational, non-gating); `complexity.cognitive` tightened to a threshold of 20 and `complexity.nesting-depth` to 4; `complexity.cyclomatic` is now `warning`. The complexity pillar now gates on the metrics that track human comprehension rather than branch-counting proxies.
 - **Config accepts `advisory` severity** - the `rules.<id>.severity` config key now accepts `advisory` alongside `warning` and `error`, so rules that default to advisory can be pinned or overridden in `.gruff-php.yaml`.

The cache is automatic and correctness-safe: it keys on file bytes + the resolved rule settings + the gruff version, so any change is a fresh analysis, and a cold cache or `--no-cache` is byte-identical to a cached run. Runs that use project rules (the default rule set) bypass the cache. Pass `--no-cache` to force a fresh analysis of every file. Add `.gruff-cache/` to `.gitignore` (gruff already ignores it during discovery).

 - `--diff=<base>` is a changed-line/file filter, not a full base/current subtraction engine.

+# ADR-021 - Config presets and `extends:` inheritance
+
+- Status: Accepted
+- Date: 2026-05-30
+- Relates to: ADR-017 (mission: gruff must be easy to adopt as a coding-agent hook)
+
+## Context
+
+A repo that wants gruff must today hand-maintain a ~560-line `.gruff-php.yaml`
+enumerating every default-enabled rule. For a stable 1.0.0 whose point is "drop me
+in as a hook", that is the dominant adoption friction. We add bundled presets and an
+`extends:` key so a config is expressed as a small delta against a known base.
+
+This is **sugar over the existing config surface**: `extends:` is a parse-time merge
+of YAML arrays that runs before the merged config is applied to `AnalysisConfig`.
+Nothing in `RuleRegistry`, `RuleSelection`, `RuleSettings`, or the rule runner
+changes.
+
+## Decision
+
+1. **Three bundled presets** under `resources/profiles/`: `gruff.recommended`,
+   `gruff.starter`, `gruff.strict`. No more (kill criterion: avoid choice paralysis).
+
+2. **`gruff.recommended` = the registry defaults**, expressed as a minimal preset
+   (schema + intent header). It deliberately does *not* copy the repo's own
+   `.gruff-php.yaml`, because that file adds extra accepted-abbreviations and
+   repo-local `pathOverrides` *beyond* the defaults — which would break the anchor
+   guarantee that `extends: gruff.recommended` with no overrides behaves identically
+   to a no-config run. `starter` and `strict` `extends: gruff.recommended` and layer
+   explicit deltas (starter narrows selection to the highest-signal pillars; strict
+   enables default-disabled rules and tightens thresholds).
+
+3. **`extends:` accepts one string** — a bundled name (`gruff.*`, resolved from the
+   package `resources/profiles/`) or a path (relative to the loading file's
+   directory, or absolute). No URLs, no list, no `imports:`.
+
+4. **Merge by layering, not array-merge.** The chain resolves to an ordered list of
+   raw configs (ancestor first, current file last); each is applied through the
+   existing apply-chain in turn, so a child's settings layer over what it inherits.
+   This reuses the validated config machinery (no separate merge code, no loosely
+   typed merged array) and yields **child-replaces-per-section** semantics: a child
+   block for a section (`paths.ignore`, `selection`, `minimumSeverity`,
+   `failureConditions`, scalars) replaces the inherited block for that section;
+   `rules.<id>` is per-rule (a child rule block replaces the parent's for that id,
+   rules only in the parent are kept); registry-seeded allowlist defaults survive
+   for sub-keys nobody sets. Predictable layering over clever merge. (Cross-source
+   **union** for shared-base lists — e.g. appending a team base's `paths.ignore` — is
+   a deferred refinement; for the common "extend a bundled preset" case the presets
+   set none of the union-relevant sections, so layering is equivalent.)
+
+5. **Cycle detection + depth cap 5.** Chains resolve depth-first with a visited set
+   keyed by canonical path / preset name; a cycle or a 6th hop throws a
+   `ConfigException` naming the chain. Unknown preset names throw, listing the three
+   valid presets.
+
+6. **Provenance.** The merged `AnalysisConfig` carries `extendsChain: list<string>`
+   (most distant ancestor first, current file last) for an effective-config surface.
+
+## Consequences
+
+- A team maintains one shared base and each repo extends it with a few lines; a new
+  user picks a preset in one line.
+- A preset-integrity test proves every rule id referenced in every preset exists in
+  the registry (no drift); a preset-identity test proves `extends: gruff.recommended`
+  equals no-config behaviour (the no-behaviour-change anchor).
+- No default behaviour changes: an absent `extends:` key means "no inheritance", and
+  the repo's own `.gruff-php.yaml` is left untouched (its migration is a separate,
+  reviewable change).

+# ADR-022: Test-quality gate parity — promote fake-test rules to error
+
+**Status:** Implemented
+**Date:** 2026-05-30
+**Author(s):** gruff maintainers
+**Updated:** 2026-05-30 — amends ADR-010 (severity calibration); extends ADR-017 (mission corollary)
+
+## Context
+
+ADR-017 names three mission legs: legible, secure, and **tested for real**. The first
+two gate hard, but the third barely participated: of 33 `test-quality` rules only two
+defaulted to `error` (`empty-data-provider`, `extends-production-class`). The rules that
+prove a test is *fake* — it asserts nothing, never calls the system under test, or asserts
+a tautology — sat at `warning`/`advisory`. An agent gating at `--fail-on error` could
+therefore ship a green suite that exercises nothing, which is exactly the failure ADR-017
+exists to prevent (a green run that no longer means the behaviour is exercised).
+
+ADR-017's calibration corollary is the test for which rules may gate: **a rule earns a
+hard severity only when the cheapest way to satisfy it is a genuinely better artifact, not
+a cosmetic edit.** For test-quality that means: the cheapest fix must be a real assertion
+or a real call to the subject, not a rename or a reformat.
+
+Evidence (dogfood + fixture corpus, `analyse --no-config` over `tests/`):
+
+- The promotion candidates fire **only** on the deliberately-bad fixtures in
+  `tests/Fixtures/TestQuality/`; they fire **zero** times on gruff's own 149-unit real
+  test suite, which uses assertion helpers, data-provider matrices, `expectException`, and
+  Pest `expect()`. That real suite is the negative corpus: the rules do not false-positive
+  on legitimate test shapes.
+- `trivial-assertion` fires 80 times even on fixtures and is broad; the mock smells have a
+  cheapest-fix that can be cosmetic. These stay at `warning`.
+
+## Decision
+
+Promote three `test-quality` rules to `error` — changing both the rule's
+`defaultSeverity` and the severity stamped on its findings:
+
+- `test-quality.no-assertions` (`warning` → `error`) — a test with no observable assertion
+  proves nothing; cheapest fix is to add a real assertion.
+- `test-quality.sut-not-called` (`advisory` → `error`) — the named subject is never
+  invoked; cheapest fix is to actually call it.
+- `test-quality.tautological-type-assertion` (`warning` → `error`) — `assertInstanceOf(X,
+  new X)` restates a static guarantee; cheapest fix is to assert real behaviour. (High
+  confidence; fires only on locally-constructed instances.)
+
+Keep at `warning`/`advisory` the rules whose cheapest fix can be cosmetic or that still
+over-fire: `mock-only-test`, `mock-without-expectation`, `trivial-assertion`,
+`trivial-snapshot`, and the style/design smells (`eager-test`, `mystery-guest`,
+`excessive-mocking`, `setup-bloat`, `magic-number-assertion`, naming/readability). Forcing
+those would manufacture ceremony — the opposite of the mission.
+
+Severity is metadata, not schema: `gruff.analysis.v2` / `gruff.baseline.v1` are unchanged.
+The two stability snapshots (rule-definition digest, fixture-finding digest) are refreshed
+in the same change.
+
+## Failure Mode Comparison
+
+| Option | What fails | Why rejected or accepted |
+| --- | --- | --- |
+| Leave all fake-test rules at warning/advisory | "Tested for real" never gates; an agent ships a green suite that asserts nothing | Rejected — defeats a core mission leg |
+| Promote all seven Objective-2 candidates to error | `trivial-assertion` (80 fixture hits, broad) and the mock smells force cosmetic edits / risk FPs | Rejected — violates the cheapest-fix-is-genuine test and the kill criteria |
+| Promote only the three FP-clean "proves-nothing" rules | — | **Accepted** — each is dogfood-proven FP-clean (realTests=0) and its cheapest fix is a stronger test |
+
+## Reversibility
+
+Two-way door. Severity is a rule-definition default plus a finding stamp; reverting is
+flipping the enums back and regenerating the two snapshot digests
+(`RuleRegistryTest`, `RuleRegressionSnapshotTest`). Revisit if a promoted rule is found to
+false-positive on a legitimate test shape in the field — harden the shape or demote, per
+the kill criteria. A consumer who disagrees can lower any rule's severity in config; the
+bundled `gruff.starter` preset already narrows scope for first adoption.

 - **New-findings-only gate (`--fail-on-new`)** - the capstone of the coding-agent-hook workflow: fail CI only on findings the change *introduced*, freezing pre-existing debt as visible-but-non-blocking. `--fail-on-new` (shorthand for `failureConditions.newFindings.severityThresholds.error: 0`, which also accepts `severityThresholds`/`total`) gates the new set, defined as `baselineNew ∩ branchIntroduced` — the post-baseline findings when `--baseline` is set, the branch-introduced findings when `--diff-vs <ref>` is set, their intersection when both are; never "all findings". Enabling it with no reference point (no baseline and no `--diff-vs`) fails fast at setup instead of failing every finding. A new-findings trip renders distinctly (`Failed: 3 new error finding(s)…`, JSON `failureReason.scope: "new"` plus a `newFindingsCount`); the total gate and the new-findings gate fire independently, with the new-findings reason winning when both trip.
 - **Incremental result cache** - cache-eligible runs (those with no project rules — e.g. the `security` profile, or a config that excludes the design/dead-code rules) now reuse unchanged files' findings across runs via a content-addressed, gitignored `.gruff-cache/`, keyed on file bytes plus the resolved rule settings plus the gruff version. A cold cache and `--no-cache` produce byte-identical output; any content, config, or version change invalidates the affected entries; runs with project rules bypass the cache entirely (their cross-file rules need every unit). The base-ref snapshot cache for `--diff-vs` is a documented follow-up (ADR-020).
+- **Config presets and `extends:`** - bundled `gruff.recommended`, `gruff.starter`, and `gruff.strict` profiles plus an `extends:` key let a repo replace a ~560-line `.gruff-php.yaml` with a few lines — `extends: gruff.recommended`, then only your overrides. `extends:` accepts a bundled preset name (`gruff.*`) or a relative/absolute path; chains resolve ancestor-first (a child's section overrides the inherited one), cycles and chains deeper than five hops fail with a clear error naming the chain, and an unknown preset name lists the valid ones. `extends: gruff.recommended` with no overrides behaves identically to running with no config file at all, and a preset-integrity test keeps the bundled presets from drifting out of sync with the rule registry (ADR-021).
 - **BREAKING: Retired the `complexity.npath` rule** - NPath produced false positives on sequential-but-simple branching and is redundant with the cognitive, cyclomatic, and nesting metrics. Remove any `complexity.npath` block from your config (it now fails closed as an unknown rule id) and regenerate baselines to drop stale npath findings. The registry now exposes 118 rules.
 - **Complexity recalibration** - `complexity.halstead-volume` and `complexity.maintainability-index` are now `advisory` (informational, non-gating); `complexity.cognitive` tightened to a threshold of 20 and `complexity.nesting-depth` to 4; `complexity.cyclomatic` is now `warning`. The complexity pillar now gates on the metrics that track human comprehension rather than branch-counting proxies.
+- **Test-quality gate parity** - the "tested for real" mission leg now gates. `test-quality.no-assertions` (a test with no observable assertion), `test-quality.sut-not-called` (the named subject is never invoked), and `test-quality.tautological-type-assertion` (`assertInstanceOf(X, new X)`) are promoted to `error`, so `analyse --fail-on error` fails a suite whose tests prove nothing — and the cheapest way to satisfy each is a real assertion. The cosmetic-fix and style smells (`mock-without-expectation`, `trivial-assertion`, `eager-test`, naming/readability, …) stay at warning/advisory so the gate never forces ceremony. Each promotion fires only on genuinely fake tests, not on assertion helpers, data-provider matrices, `expectException`, or Pest `expect()` (ADR-022).
 - **Config accepts `advisory` severity** - the `rules.<id>.severity` config key now accepts `advisory` alongside `warning` and `error`, so rules that default to advisory can be pinned or overridden in `.gruff-php.yaml`.
 - **Mission documented** - a stated project mission (governing AI-generated code for human verifiability) now anchors `README.md`, `docs/mission.md`, and the agent instructions, recorded in ADR-017.

+## Config presets (`extends:`)
+
+Instead of hand-maintaining a long `.gruff-php.yaml`, extend a bundled preset and add only your deltas:
+
+```yaml
+schemaVersion: gruff-php.config.v0.1
+extends: gruff.recommended   # or gruff.starter (lean) / gruff.strict (tighter)
+rules:
+  complexity.cognitive:
+    threshold: 25            # your override on top of the preset
+```
+
+- `gruff.recommended` — gruff's default rule set; `extends: gruff.recommended` with no overrides behaves exactly like no config at all.
+- `gruff.starter` — the highest-signal pillars only (security, sensitive-data, size, complexity) for first adoption; far fewer findings.
+- `gruff.strict` — recommended plus tighter complexity/size thresholds.
+
+`extends:` also accepts a relative or absolute path (`extends: ./shared.gruff-php.yaml`) so a team can share one base. Chains resolve ancestor-first (a child's section overrides the inherited one); cycles, chains deeper than five hops, and unknown preset names fail fast with a clear error. Use `--config <path>` to point at a specific config file.
+
 ## Result cache
 
 Cache-eligible runs (no project rules active — e.g. `--profile security`, or a config that excludes the design/dead-code rules) reuse unchanged files' findings across runs from a content-addressed, gitignored `.gruff-cache/`. The cache is automatic and correctness-safe: it keys on file bytes + the resolved rule settings + the gruff version, so any change is a fresh analysis, and a cold cache or `--no-cache` is byte-identical to a cached run. Runs that use project rules (the default rule set) bypass the cache. Pass `--no-cache` to force a fresh analysis of every file. Add `.gruff-cache/` to `.gitignore` (gruff already ignores it during discovery).

 1. **Legible enough to verify.** Complexity and nesting are capped so a method fits in a reviewer's head, and every method — public or private — must carry an intent-bearing doc comment stating what it is for, what it returns at the edges, and what the caller must satisfy. The comment is a plain-English contract the reviewer checks the implementation against. A doc comment that contradicts the code is a signal the change needs a deeper look — not noise.
 2. **Secure where the eye fails.** The `security` and `sensitive-data` pillars catch the classes of mistake a human reviewer skims past: injection, unsafe deserialization, leaked secrets, weak crypto, and similar.

+# Discipline
+
+Lessons about honest progress tracking and not cutting corners.
+
+## Lesson: Tick task checkboxes the moment the item is done, never in a batch at the end
+
+**Created:** 2026-05-31
+
+**Trigger:** Working a `.goat-flow/tasks/` milestone (or any file with `- [ ]` items) across multiple steps.
+
+**Do:** The instant a checklist item is genuinely done and verified, flip its `- [ ]` to `- [x]` in the *same* edit that finishes the work. A ticked box must be a fact that was true when you ticked it.
+
+**Never:** Leave the boxes unticked and lean on a `Status: complete` + Close-out section instead, then retro-tick in bulk (`sed 's/- \[ \]/- [x]/g'`). A blanket tick cannot tell *done* from *deferred*, so it marks deferred work complete — a false-completion claim, the exact failure gruff-php exists to prevent.
+
+**When you defer or skip an item:** leave it `- [ ]` and say why on the line or in a Deferred note. Unchecked is honest; a wrong check is a lie. When unsure whether an item is truly done, leave it unchecked.
+
+**What this cost (2026-05-31):** Finished M06–M15 marking only Status + Close-out, every box left unticked. Asked to tick them, I blanket-`sed`-ticked — which falsely marked M09's deferred config-subcommand + `extendsChain` items and M13's deferred FP-guard fixtures as done, and I had to detect and hand-revert them. Ticking as I went would have made the bulk pass unnecessary and impossible to get wrong.

Subject: [PATCH 11/25] Decompose AnalyseCommand into AnalysisFindingSupport
 and BranchReviewBuilder collaborators, reduce FailThresholds and
 SourceDiscovery cognitive complexity, tighten identifier naming and   PHPDoc
 coverage, and exempt nullable bags in phpdoc-mixed-overuse.

 # CLI Command Footguns
@@ -15,6 +15,16 @@ last_reviewed: 2026-05-24
 
 **Prevention:** Any prompt that performs a filesystem side effect must run after all input validation completes — including validation done by a delegated subprocess. For commands that forward options to another command, either pre-validate the forwarded options locally before the prompt, or move the prompt past the subprocess invocation so the side effect only runs once the subprocess has accepted the inputs. The pattern file `.goat-flow/patterns/commands.md` records the canonical execute() order.
 
+## Footgun: Editing above a baseline-suppressed finding resurfaces it as a new finding
+
+**Status:** active | **Created:** 2026-05-31 | **Evidence:** OBSERVED
+
+The default-applied `gruff-baseline.json` matches accepted-debt findings to live findings purely by `fingerprint`: `src/Baseline/BaselineFilter.php` (search: `$entriesByFingerprint`) indexes entries by `BaselineEntry::fingerprint` and looks each finding up by `Finding::fingerprint()`. That fingerprint hashes the finding's `line`/`endLine`/`column` — `src/Finding/Finding.php` (search: `'line' => $this->line`) — and matching has no line-insensitive fallback (`Finding::stableIdentity()` is computed but never consulted during baseline matching). So inserting or deleting any line *above* a suppressed finding shifts its line, changes its fingerprint, un-matches the baseline entry, and the previously-accepted finding re-appears as `new` (failing `--fail-on advisory`). During the 0.3.0 self-scan cleanup, four accepted-debt findings (`PhpDocMixedOveruseRule::hasSignatureBroadTypeCoverage` cognitive, `isPreciseArrayShape` regex-comment, `topLevelColonIndex` missing-return, `AnalyseCommandOptions::diffMode` missing-return) each resurfaced this way after an unrelated edit earlier in the same file.
+
+**Evidence:** `src/Baseline/BaselineFilter.php` (search: `$entriesByFingerprint[$fingerprint]`) is fingerprint-only; `src/Finding/Finding.php` (search: `function fingerprint`) shows `line` is part of the hash. The analyse output's "Movement: N new" line and "Stale entries" tip surface the resurfaced findings.
+
+**Prevention:** When refactoring a file that carries baseline-suppressed findings, first run `grep <ClassName> gruff-baseline.json` to learn which findings it has accepted, then either (a) add the new code *below* every suppressed finding and keep any edit above them net-zero in line count — the trick used to keep `stripTopLevelNullUnion` from shifting `PhpDocMixedOveruseRule`'s baselined methods — or (b) fix the resurfaced finding for real, or (c) regenerate with `gruff-php analyse --generate-baseline gruff-baseline.json` after reviewing the movement diff.

 **Evidence:** `tests/Command/MissingConfigPromptTest.php` (search: `extends BufferedOutput implements ConsoleOutputInterface`) is the canonical post-fix example. The `tests/Fixtures/**` entry in `.gruff-php.yaml` (search: `tests/Fixtures/**`) ignores the fixture corpus that gruff scans as analysis input, but real PHPUnit test files under `tests/Command`, `tests/Console`, `tests/Rule`, etc. are in scope.
 
 **Prevention:** Write anonymous classes in tests the same way you'd write a production class — PHPDoc on every public method, parameter names that match the type convention (`$bufferedOutput`, not `$stdoutBuffer`), no empty method bodies, no throw-only one-liners. For unavoidable interface-required no-ops, use `unset($parameter)` (parses as `Stmt\Unset_`, which `waste.one-line-method` skips because the rule only checks `Return_` and `Expression` statements). For interface methods that must throw because of a non-nullable return type, split the body into two statements (assign the message to a local, then `throw new ...($message);`) and add a `@throws` tag. The worked-out shape lives in `.goat-flow/patterns/tests.md` "Intersection-typed test fake for stream routing".

+## Footgun: The obvious data-provider consolidation trips phpdoc-mixed-overuse and the public-method cap

+
+`test-quality.repeated-structure-missing-data-provider` (`src/Rule/TestQuality/RepeatedStructureMissingDataProviderRule.php`, search: `MIN_GROUP_SIZE`) pushes three-plus structurally-identical tests toward a `#[DataProvider]`, but the naive consolidation trips two other gates that score `tests/` like production code:
+
+- A provider yielding heterogeneous config inputs wants `@return iterable<string, array{array<array-key, mixed>, string}>`, and `modernisation.phpdoc-mixed-overuse` fires on the nested `mixed` because the unstructured-bag exemption in `src/Rule/Modernisation/PhpDocMixedOveruseRule.php` (search: `isUnstructuredArrayBagType`) only applies when `array<…, mixed>` is the *top-level* tag type, not nested inside `iterable<…>`. PHPStan runs at level 10 (`phpstan.neon.dist`, search: `level: 10`), so a bare `array` value type is rejected too. Fix: yield each malformed input as a JSON *string*, then `json_decode` it inside the test behind a top-level `/** @var array<array-key, mixed> $config <reason> */` (a top-level bag *is* exempt). Worked example: `tests/Reporting/FailThresholdsTest.php` (search: `invalidFailureConditionsProvider`).
+- The new public provider method plus the split test methods count toward `size.public-method-count` (cap 25 in `.gruff-php.yaml`, search: `size.public-method-count`). `tests/Config/ConfigLoaderTest.php` (search: `testExcludeFromScoreDefaultsToFalseAndHonoursOverrides`) was already at the cap, so a three-cycle test was kept as one method that batches all arrange/act then all asserts — a single act→assert transition satisfies `test-quality.multiple-aaa-cycles` (minCycles 3) without adding a method.
+
+**Evidence:** Both findings surfaced mid-cleanup after consolidating the four `FailThresholds::fromConfig` rejection tests and splitting the ConfigLoader excludeFromScore test; the self-scan went back to zero only after the JSON-string provider and the batched-AAA rewrite.
+
+**Prevention:** Before consolidating, check the test class's public-method count and whether the provider's `@return` will nest `mixed`. Prefer JSON-string provider rows for heterogeneous inputs; when the class is near the 25-method cap, satisfy `multiple-aaa-cycles` by batching arrange-act-then-assert in one method instead of splitting into new public methods.

-First stable release. gruff-php sharpens around a single mission — governing AI-generated code so a human who didn't write it can read, verify, and trust it — and commits to a stable rule and schema surface. The headline breaking change retires the noisy `complexity.npath` rule and recalibrates the complexity pillar toward the metrics that track human comprehension; changed-region analysis lands — and `paths.ignore` becomes authoritative across every scan mode — so coding-agent hooks see only the lines they touched and never the code the project deliberately excluded. A baseline-aware gate chain (three-state baseline reporting, per-severity count thresholds, and the `--fail-on-new` capstone) completes that workflow: CI can fail only on the debt a change introduces, freezing existing debt as visible-but-non-blocking.
+gruff-php sharpens around a single mission — governing AI-generated code so a human who didn't write it can read, verify, and trust it — and hardens its rule and schema surface while staying pre-1.0. The headline breaking change retires the noisy `complexity.npath` rule and recalibrates the complexity pillar toward the metrics that track human comprehension; changed-region analysis lands — and `paths.ignore` becomes authoritative across every scan mode — so coding-agent hooks see only the lines they touched and never the code the project deliberately excluded.

 - **Changed-region analysis** - `analyse` now accepts `--changed-ranges`, `--since`, bare `--diff`, `--diff -`, and `--changed-scope=symbol|hunk` so hook consumers can request only findings attributable to the edited region. JSON reports include `suppressedCount` when this mode filters out pre-existing findings.
 - **Ignore reasons and `check-ignore`** - the JSON report's new additive `ignoredPathDetails` field records why each path was excluded — its `source` (`config`, `default`, `generated`, or `gitignore`) and matching `pattern` — alongside the existing `ignoredPaths` list. A new `check-ignore [--format text|json] [--config <path>|--no-config] <path>...` command answers whether gruff would ignore a path, and why, without running an analysis (JSON `[{path, ignored, source, pattern}]`; exit codes mirror `git check-ignore`). `paths.ignore` stays authoritative in every mode — explicit file operands and all diff/changed-region scans, not just the directory walk — and `--include-ignored` never overrides it (ADR-019).

 - **Test-quality gate parity** - the "tested for real" mission leg now gates. `test-quality.no-assertions` (a test with no observable assertion), `test-quality.sut-not-called` (the named subject is never invoked), and `test-quality.tautological-type-assertion` (`assertInstanceOf(X, new X)`) are promoted to `error`, so `analyse --fail-on error` fails a suite whose tests prove nothing — and the cheapest way to satisfy each is a real assertion. The cosmetic-fix and style smells (`mock-without-expectation`, `trivial-assertion`, `eager-test`, naming/readability, …) stay at warning/advisory so the gate never forces ceremony. Each promotion fires only on genuinely fake tests, not on assertion helpers, data-provider matrices, `expectException`, or Pest `expect()` (ADR-022).
 - **Config accepts `advisory` severity** - the `rules.<id>.severity` config key now accepts `advisory` alongside `warning` and `error`, so rules that default to advisory can be pinned or overridden in `.gruff-php.yaml`.
 - **Mission documented** - a stated project mission (governing AI-generated code for human verifiability) now anchors `README.md`, `docs/mission.md`, and the agent instructions, recorded in ADR-017.
+- **Nullable JSON-boundary bags exempt from `phpdoc-mixed-overuse`** - `modernisation.phpdoc-mixed-overuse` no longer fires on a nullable unstructured bag such as `array<string, mixed>|null` — the honest type of a `json_decode` helper that returns the decoded object or `null` — matching the existing exemption for the non-null `array<string, mixed>` form. Standalone `mixed` and concrete-keyed shapes still fire.
+- **Clean self-scan** - gruff-php's own source now passes `gruff-php analyse` with zero unsuppressed findings: the `AnalyseCommand` god-object is decomposed into `AnalysisFindingSupport` and `BranchReviewBuilder` collaborators, the `--no-cache` flag moves onto `AnalyseCommandOptions`, and the `FailThresholds` / `SourceDiscovery` hotspots drop below the cognitive-complexity gate. No CLI behaviour or output schema changes.

 7. For each discovered file, `PhpFileParser::parse()` reads the source. PHP files are parsed by `nikic/php-parser` and decorated with a `ParentConnectingVisitor`; non-PHP text/config files short-circuit to an `AnalysisUnit` with raw source but no AST or tokens. Parse failures produce one `ParseDiagnostic` per error and are surfaced as `parse-error` `RunDiagnostic` entries.
 8. `RuleRegistry::analyse()` skips units with parse errors, then iterates rules allowed by `RuleSelection` and per-rule `enabled` settings. Two rule shapes are supported (see ADR-003): per-unit rules implementing `RuleInterface` see one `AnalysisUnit` at a time, and project rules implementing `ProjectRuleInterface` run once over the full list of parse-clean PHP units after the per-unit loop. PHP-only rules run only against `SourceFile::isPhp()` units; rules implementing `SourceTextRuleInterface` also run against text/config units, so secret/PII scanners cover JSON, YAML, env, Markdown, TOML, shell, and similar files. Overlapping naming findings on the same identifier are reduced by rule priority (`class-file-mismatch > confusing-name > negative-boolean > boolean-prefix > identifier-quality > hungarian-notation > suffix-hungarian > short-variable > abbreviation-allowlist`), then findings from all units are sorted by `(filePath, line, ruleId, message)` for deterministic output. Project rules currently power `design.single-implementor-interface`.
 9. If `--infection-report` is supplied, `InfectionReportParser` ingests the full Infection JSON report, calculates per-file mutation summaries, and `MutationFindingFactory` appends `mutation.survived-mutant`, `mutation.budget-exceeded`, and `mutation.msi-regression` findings where applicable. `--infection-run` is explicit opt-in and only shells out through `InfectionRunner`; it requires a report path because Infection controls full JSON log output through its config.
-10. `CompositeFindingFactory` appends `design.god-method` findings when size and complexity findings overlap on the same symbol.
-11. If `--diff-vs=<base>` is supplied, `GitDiffProvider` reads changed files from Git and `GitArchiveSnapshot` builds a temporary base-ref snapshot without mutating the worktree. `BranchReviewComparator` compares current and base findings by `file + ruleId + symbol`, falling back to `file + ruleId + message`, and exposes introduced/removed/unchanged sets plus score delta. `--changed-only` limits both comparison sets to changed files; when no explicit paths are supplied, `analyse` uses the Git changed-file list as the current-tree analysis path list instead of first discovering the whole project. Base snapshots are path-limited before extraction by resolving candidate paths against the base ref with `git ls-tree -r --name-only`, then archiving only the matching base files. If `--diff` is supplied instead, `GitDiffProvider` reads changed files and new-line ranges from Git (`working-tree`, `staged`, `unstaged`, or a base ref), and `DiffFindingFilter` keeps only findings touching changed lines or changed files.
-12. Configured secret preview allowlists remove matching `SensitiveData` findings by redacted preview, after rules run and before scoring.
-13. If `--generate-baseline` is supplied, `BaselineStore` writes the current scoped findings to a `gruff.baseline.v1` JSON file (defaulting to `gruff-baseline.json` at the project root, overwriting silently). If `--baseline` is supplied, `BaselineStore` reads that file and `BaselineFilter` suppresses matching findings by fingerprint, rule id, and file path. With no explicit baseline flag, `AnalyseCommand` auto-discovers `gruff-baseline.json` at the project root and applies it unless `--no-baseline` is set. The `BaselineReport` payload distinguishes `source: "explicit"` from `source: "default"` so reporters can communicate whether application was auto-discovered. Stale entries are evaluated only in full-project scope; diff scope reports that stale evaluation is skipped.
-14. `ScoreCalculator` computes per-pillar scores, top-offender file scores, complexity distribution buckets, optional mutation scoring, and the composite A-F grade. In the default profile, the composite averages all built-in static pillars; in `--profile=security`, it averages only `security` and `sensitive-data` so untouched quality pillars do not dilute security findings. If `--history-file` is supplied, `TrendRecorder` appends a bounded JSON history entry.
-15. Display filters (`--min-severity`, `--include-pillar`, `--exclude-pillar`, `--include-rule`, `--exclude-rule`) are applied after scoring, baseline handling, and branch-review comparison, then recorded in `run.filters` so downstream tools know the report is filtered.
-16. `AnalyseCommand` builds an `AnalysisReport` with tool/run metadata, summary counts, ignored/missing paths, diagnostics, findings, optional mutation data, score, diff metadata, optional branch-review metadata, optional trend data, optional baseline metadata, and display-filter metadata, then renders it via the selected reporter. HTML rendering also consumes render-only options for editor links (`none`, `vscode`, `phpstorm`) and opt-in interactive findings controls. Reporter output is written using `OutputInterface::OUTPUT_RAW` so Symfony Console does not scan rendered HTML/JSON/Markdown/SARIF payloads as console formatting tags.
-17. `resolveExitCode()` returns `Command::INVALID` (`2`) if any `RunDiagnostic` was recorded, `Command::FAILURE` (`1`) when at least one finding satisfies `--fail-on`, and `Command::SUCCESS` (`0`) otherwise.
-18. `ReportCommand` builds a safe Symfony Process argument vector for `bin/gruff-php analyse <paths> --format <html|json> --fail-on <threshold>`, preserving supported analysis options including `--baseline`, `--no-baseline`, `--diff-vs`, display filters, `--report-editor-link`, and `--report-interactive`, then writes the static report to stdout (also via `OUTPUT_RAW`) or to `--output`.
-19. `DashboardCommand` binds a local socket (default port 8765 on 127.0.0.1), renders a control page at `GET /` (including baseline, config, scan-scope, include-ignored, and interactive-findings controls), re-runs analysis at `GET /scan` using query-supplied project root, paths, baseline, config, scan scope, include-ignored, and report-interactive state, injects scan metadata into the HTML report, and exposes `GET /health` for smoke tests. The config control defaults to `.gruff-php.yaml` without pinning an absolute project root; the scan-scope control maps `whole branch` to a full selected-path scan and `diff only` to `analyse --diff`. The scan metadata command line is displayed in a wrapping copyable field. The dashboard does not expose a mutation trigger and the HTML report omits the mutation pillar/chart; full Infection runs are driven from `scripts/mutation-test-full.sh` or by passing `--infection-run --infection-report` to `analyse` directly. `scripts/start-dev.sh` starts the dashboard with environment-overridable host, port, project root, and scan timeout.

 Static finding baselines default to `gruff-baseline.json` at the project root: `--generate-baseline` writes it (overwriting silently), bare `--baseline` or no flag at all picks it up automatically, `--baseline=<path>` forces an explicit file, and `--no-baseline` opts a single run out. Mutation-specific baseline MSI comparison remains separate through `--mutation-baseline`.
 
 ## Rule Catalogue
 
-The default registry-backed static rule set covers 11 emitted pillars (`Size`, `Complexity`, `Maintainability`, `DeadCode`, `Naming`, `Documentation`, `Modernisation`, `Security`, `SensitiveData`, `TestQuality`, `Design`) and currently exposes 118 rule ids through `list-rules --format json`. `waste.*` rule ids are historical names that emit either `DeadCode` or `Maintainability` findings. Infection ingestion can also emit `Mutation` pillar findings, and `CompositeFindingFactory` can emit a `Design` pillar composite finding when size and complexity findings overlap on the same symbol. All emitted rules are tier `v0.1`; `Coupling` and `Architecture` remain reserved.

 # ADR-006: Control-Flow Comment Policy
 
-**Status:** Implemented

 **Date:** 2026-05-13
-**Ticket/Context:** M37 modernisation, naming, and control-flow comment policy
+
+## Update (2026-05-31): return-comment restored
+
+`docs.return-comment` is reinstated as the original blanket rule: a one-line comment directly above every `return`. The earlier deletion treated it as low-signal ceremony, but that mis-read the rule's purpose. gruff governs AI-generated code so a human who didn't write it can verify it; a comment stating *why* each exit returns is a verification surface a reviewer diffs against the code — the same principle that makes doc comments mandatory. The rule stays advisory, and like other debt-heavy rules its existing-code findings are meant to be frozen via the baseline so it gates new and changed returns rather than forcing a backfill of gruff's own tree. `docs.continue-comment` remains deleted; only the return variant is restored, so the rest of this ADR's reasoning still applies to the continue rule.

+# ADR-023: Retire `design.god-method`
+
+**Status:** Accepted
+**Date:** 2026-05-31
+**Author(s):** Matthew Hansen
+**Supersedes scope of:** ADR-018 only where it preserved the `design.god-method`
+trigger after removing `complexity.npath`.
+
+## Context
+
+`design.god-method` was a synthetic finding emitted outside `RuleRegistry` by
+`src/Scoring/CompositeFindingFactory.php` when size and complexity findings
+overlapped on the same method/function symbol. It carried `Pillar::Design` and
+`metadata.componentRules`, then `ScoreCalculator` had a registry-missing special
+case so `excludeFromScore` could be inherited from the component rules.
+
+ADR-018 narrowed the trigger to `{complexity.cognitive, complexity.cyclomatic,
+complexity.nesting-depth}` after retiring `complexity.npath`. That kept the
+synthetic rubric alive, but the surviving component findings already name the
+actionable problems: too much size, too much cognitive/cyclomatic complexity, or
+too much nesting. The synthetic design label adds a second finding and a scoring
+branch without adding a remediation path that is not already implied by the
+component findings.
+
+## Decision
+
+Retire `design.god-method` completely in 0.3.0.
+
+- Delete the synthetic emission path instead of keeping an opt-in or warning-only
+  version.
+- Keep the underlying size and complexity findings visible and scored through their
+  native pillars.
+- Keep `design.single-implementor-interface`; this decision only removes the
+  synthetic `design.god-*` rubric family.
+- Remove `metadata.componentRules` scoring inheritance once no live synthetic
+  component-rule finding remains.
+
+This is a breaking rule-id retirement even though the rule was not registry-backed.
+Users with stale `design.god-method` entries in `gruff-baseline.json` should remove
+those entries or regenerate the baseline after reviewing the diff.
+
+## Failure Mode Comparison
+
+| Option | What fails | Why rejected or accepted |
+| --- | --- | --- |
+| Keep `design.god-method` | One root cause can appear as size, complexity, and synthetic design findings; the synthetic finding needs custom scoring and docs despite no unique remediation. | Rejected. Duplicate abstraction is not worth the maintenance surface. |
+| Make it scoring-only | Hides the visible rule id but keeps a hidden coupling between unrelated pillars and still requires special scoring behavior. | Rejected. If the signal is duplicate, remove it rather than making it implicit. |
+| Demote or disable by default | Keeps a dormant non-registry rule id and the `componentRules` scoring branch for a finding most users will not need. | Rejected. Same maintenance problem with less visible value. |
+| Delete the synthetic rubric | Users lose the roll-up label, but still see every actionable size and complexity component finding. | Accepted. Smallest surface and clearest report. |
+
+## Consequences
+
+- `src/Scoring/CompositeFindingFactory.php` and its `analyse`, `summary`, and
+  branch-review call sites are removed.
+- Reports no longer emit `design.god-method`; baselines containing it become stale
+  debt records to remove.
+- `ScoreCalculator` no longer needs registry-missing `metadata.componentRules`
+  inheritance for `excludeFromScore`.
+- The design pillar remains via `design.single-implementor-interface`.
+- Registry counts do not change because `design.god-method` was never
+  registry-backed.
+
+## Reversibility
+
+Two-way door before 1.0, but reversing requires a new ADR because it reintroduces a
+non-registry finding path. A future design roll-up should be implemented as a normal
+registry-backed rule or as a documented report aggregation, not by reviving the old
+synthetic finding unchanged.

+# Code Comments
+
+Use this when writing or editing source code in any language, before deciding whether to add a comment, docstring, or annotation. It owns two things: which *inline* comments earn their place (a small number), and how to write the doc comments that are mandatory on every function/method and class/file - so the next human maintainer can follow the code and modify it safely.
+
+The playbook is portable across TypeScript, Python, Go, Rust, and shell. It defers to each language's docstring conventions for core SYNTAX (JSDoc, PEP 257, godoc, rustdoc), but owns the WHEN/WHY decision plus a small set of house layout conventions (tag separator, blank line before tags, line width) that override the language default where they differ.
+
+## Availability Check
+
+This is a discipline reference, not a runnable tool. Load it when:
+
+- About to write a comment, docstring, or annotation inside a source file.
+- Editing existing code that contains comments - to decide keep / rewrite / delete.
+- Authoring a TODO / FIXME / HACK marker.
+- Reviewing a diff that adds or changes comments.
+
+Enforcement is partial. Where the gruff analyzer is installed (see `gruff-code-quality.md`) it flags some of the `[static]` items - notably missing doc comments, as `docs.missing-*` findings - but it isn't on every project and doesn't cover the `[judge]` semantic checks. So verify at review time against the Verification Gate below: the gate is the spec, gruff enforces the mechanical slice it can, and a reviewer or review-judge owns the rest. Don't claim more enforcement than the project actually runs.
+
+## Intent
+
+You are a coding agent, and a human who didn't write this code has to read, review, and trust it. This playbook optimises for that - governing AI-generated code so a reviewer can verify it does what was asked - not for minimal human-authored documentation. Your job is to write comments that let that reviewer follow the code and check your intent against your implementation. When a rule here is stricter than a hand-written codebase would need (mandatory doc comments on every unit, the verification gate), that goal is why.
+
+The project default is: no INLINE comment unless the WHY is non-obvious. Most "explanatory" inline comments are restating what the code already says, or recording details that will rot the moment the surrounding code shifts. Doc comments on functions/methods and classes/files are the standing exception - those are always written; see "Docstring vs Inline".
+
+For inline comments, this playbook covers what to do when the WHY *is* non-obvious - how to write the small number that earn their place, and how to recognise the much larger number that don't.
+
+If uncertain whether an *inline* comment materially helps the next maintainer, omit it - slightly under-commented code is easier to work with than narrated code. This omit-by-default applies to inline comments only; doc comments are required regardless.
+
+If a comment no longer matches the code, delete or rewrite it immediately. An incorrect comment is worse than a missing one - the next reader will trust it and act on it.
+
+## Rules at a glance
+
+Apply these directly; the sections below give the examples and rationale.
+
+- **Doc comment REQUIRED** on every function/method and class/file: contract + orientation, 1-5 lines for a function, 3-10 for a class/file, blank ` *` line before the tags.
+- **Inline comment ONLY for** a hidden constraint, subtle invariant, workaround, or surprising behaviour - otherwise rewrite (rename / extract / simplify) or omit.
+- **Prefer a test or assertion** over a comment when it can carry the invariant (the Enforce rung).
+- **Tags:** `@param name - description` / `@returns value - description` - real descriptions, never restated types.
+- **Wrap ~110 chars** (hard max 120); **`YYYY-MM-DD`** date or a trigger on every TODO / FIXME / HACK.
+- **Never:** markdown/emoji, commented-out code, secrets/PII/hostnames, or position/line-number references.
+- **Why it's strict:** the comment is a verification surface - state intent so a reviewer can diff it against the code.
+
+## Rewrite First
+
+Before reaching for a comment, walk this ladder:
+
+1. **Rename.** Can a better identifier carry the meaning? `t` → `timeoutMs`. `processData` → `stripPiiFromInbound`. Most "explanatory" comments dissolve under a single rename.
+2. **Extract.** Can a named function carry the meaning? A ten-line block that wants a header comment usually wants to be its own function with that header text as the name.
+3. **Simplify.** Can the control flow be untangled? Early returns, guard clauses, and flattening usually beat a comment explaining the nesting.
+4. **Enforce.** Can a test or a debug assertion carry the invariant instead of prose describing it? A comment can't protect itself; an assertion can, and it fails loudly when violated.
+5. **Then comment.** If intent still isn't visible after the four above - write the comment.
+
+The clearest comment is often the rename that made it unnecessary.
+
+**The Half-Life Test.** A good comment survives variable renames, function extraction, code movement, and reformatting; a bad one dies the moment an implementation detail changes. Anchor every comment to a constraint that will still be true in two years - a vendor contract, a regulation, an invariant - not to a person, ticket, or sprint. If renaming a variable or reordering functions would invalidate it, the comment is describing implementation detail, not intent, and it should be code, not prose.
+
+### The ladder in action
+
+Bad:
+```ts
+// Skip admin users.
+for (const u of users) {
+  if (u.role === "admin") continue;
+  notify(u);
+}
+```
+
+Good (extract + rename, no comment needed):
+```ts
+const nonAdminUsers = users.filter(u => u.role !== "admin");
+for (const user of nonAdminUsers) notify(user);
+```
+
+The original comment was a naming failure. Step 1 of the ladder (rename + extract) does the same work without the prose, and the result can't drift.
+
+## Comment Decision
+
+One routing tree; the sections below detail each branch. Doc comments are not on the "earn it" path - every unit gets one - so the tree separates that from the rationed inline decision.
+
+```text
+Writing a function/method or class/file?
+  → A doc comment is REQUIRED. Write contract + orientation. See "Docstring vs Inline".
+
+Considering an INLINE comment inside the body?
+  ├─ Can a rename or extract make it unnecessary?   → do that (see "Rewrite First")
+  ├─ Can a test or assertion carry the invariant?   → enforce it, no comment
+  ├─ Hidden constraint / subtle invariant /
+  │  workaround / surprising behaviour?             → write the inline comment
+  └─ none of the above                              → no comment
+```
+
+## WHY, not WHAT
+
+The code already says what. Comments say why.
+
+Bad:
+```ts
+// loop through users and send each an email
+for (const user of users) sendEmail(user);
+```
+
+Good (same code, comment names what the reader can't see):
+```ts
+// Vendor API rate-limits at 100 req/s; batch size upstream guarantees we stay under.
+for (const user of users) sendEmail(user);
+```
+
+The second names a constraint visible nowhere in the code.
+
+A useful shape for the WHY: **Because [constraint], we do [choice]; prevents [failure], removable when [condition].** Not every comment needs all four clauses, but the strongest ones name the constraint and the failure they prevent.
+
+Rank the WHY by how hard it is to recover. **Business, domain, legal, compliance, vendor, and operational rationale beats implementation rationale** - the former is impossible to infer from the code, the latter a careful reader can often reconstruct. `// Regulation requires rounding before the tax calculation` earns its place more than `// loop is unrolled for speed`.
+
+## Docstring vs Inline
+
+The default-no-comment stance governs INLINE comments. Doc comments are the standing exception: every function/method and every class/file carries one. They are mandatory, not earn-their-place - the orientation they give is how a maintainer understands a unit without reading its whole body. Size the description block to what it documents: 1-5 lines for a function/method, 3-10 lines for a class/file (which carries more - its role in the system, when to use it, and the broader context). Trivial units (obvious getters, one-line pure helpers) still get a doc comment - keep it to a single tight line stating the contract; the mandate is to always orient, not to pad.
+
+Why mandatory, even on a private one-liner: a doc comment is not only documentation, it is a verification surface. Coding agents routinely produce code that superficially works while misunderstanding the requirement. Forcing the agent to state intent, usage, contract, and failure behaviour in prose gives a reviewer something to check the implementation against - a mismatch between the doc comment and the code is a signal the change needs a deeper look. That is why the rule is strict, and why "keep it tight" is the tension-breaker, not an exemption: a private helper gets a one-line contract (orientation), never a padded block.
+
+What this looks like when it fires:
+```ts
+/**
+ * Returns the user's active subscriptions, sorted by renewal date (soonest first).
+ *
+ * @param userId - account to look up
+ * @returns active subscriptions; empty array when the user has none
+ */
+function activeSubscriptions(userId: string): Subscription[] {
+  return subs.filter(s => s.userId === userId && s.status === "active");
+}
+```
+The doc comment promises a sort by renewal date; the code never sorts. That mismatch is the catch - either the requirement included ordering and the implementation is wrong, or the comment overstates the contract, and either way it is the signal to review before merging. A reviewer reading only the code might assume order wasn't required; the doc comment is what makes the gap visible. That is the verification surface doing its job, and it is why the comment has to state intent even when the code "looks done".
+
+A doc comment does two jobs - state the contract and orient the reader:
+
+- **Contract:** inputs, outputs, errors, invariants - what the caller can rely on.
+- **Orientation:** when to use it (and when not to), how it fits the bigger picture, what a null/empty return or unmet precondition means, and the footguns a caller will hit.
+
+Format it consistently:
+
+- **Real descriptions, not restated types.** Document every parameter and return with meaning; prefer the language's structured doc form (JSDoc, PEP 257, godoc, rustdoc) over a bare inline comment.
+- **Hyphen-separate each tag's subject from its description**, so the line reads as label then explanation: `@param value - parsed JSON ...`, `@returns true - when value is a non-null object`.
+- **Blank ` *` line between the description block and the tags**, so a multi-line description doesn't run straight into the tags as a wall of text.
+
+Inline comments are the part this playbook rations: write one only when the WHY is non-obvious (the four cases below), and only after the rewrite-first ladder. Inline comments document rationale invisible from the signature (why this branch, why this constant, why this workaround).
+
+Wrap every comment line - doc or inline - at about 110 characters. Padding to 50-70 makes a multi-line comment needlessly choppy; 120 is the hard ceiling, so don't run past it.
+
+Docstring:
+```python
+def parse_iso_date(value: str) -> date:
+    """Parse a date-only ISO 8601 string (`YYYY-MM-DD`) from trusted internal input.
+
+    Raises ValueError on anything it can't parse - callers treat that as a hard
+    input error, not a missing value. Not a general datetime parser.
+    """
+    return date.fromisoformat(value)
+```
+
+Inline:
+```python
+def schedule_retry(attempt: int) -> float:
+    # Upstream API throttles aggressively after the third retry; cap backoff at 30s.
+    base = 0.5 * (2 ** attempt)
+    return min(base, 30.0)
+```
+
+Full shape (JSDoc) - description block, blank ` *` line, then tags:
+```ts
+/**
+ * What the unit is for, when to use it, how it fits, and the footguns a caller hits -
+ * one description block, then the tags.
+ *
+ * @param value - parsed JSON of unknown shape (e.g. JSON.parse output) to test
+ * @returns true - when value is a non-null, non-array object, narrowed to JsonObject
+ */
+```
+
+Null/empty contract - say what the absent value *means*, since the signature can't:
+```ts
+/**
+ * Look up a user by email.
+ *
+ * @param email - address to match, case-insensitive
+ * @returns the user, or null - null means "no such user" (an expected miss, not an error);
+ *   malformed input throws instead
+ */
+```
+
+## When a Comment Helps the Next Reader
+
+Four cases. If a comment fits one of these, it's earning its place. Put it immediately above the line or block it explains - at the decision point, not floating at the top of the function where the reader can't connect it to the code.
+
+### Hidden constraint
+
+Something the code can't encode about its environment - rate limits, vendor API contracts, regulatory rules, hardware quirks.
+
+Bad:
+```python
+# parse the date
+parsed = datetime.strptime(value, "%Y-%m-%d")
+```
+
+Good:
+```python
+# Vendor exports omit the timezone; treat as source-local by contract.
+parsed = datetime.strptime(value, "%Y-%m-%d")
+```
+
+The good one names the upstream contract the code can't encode.
+
+### Subtle invariant
+
+A condition the code depends on but doesn't enforce.
+
+Bad:
+```python
+def median_response_time(samples: list[float]) -> float:
+    # find the middle element
+    return samples[len(samples) // 2]
+```
+
+Good:
+```python
+def median_response_time(samples: list[float]) -> float:
+    # Caller sorts; sorting here would dominate the hot path.
+    return samples[len(samples) // 2]
+```
+
+The good one names the load-bearing assumption the signature doesn't show. An assertion would be more durable than prose (the Enforce rung) - but here `assert samples == sorted(samples)` would re-sort and defeat the very hot-path point the comment makes, so the comment is the right tool. Reach for Enforce only when the check is affordable.
+
+### Workaround
+
+Strange code that exists because of a bug or constraint elsewhere. Include enough context that the workaround can be removed once the cause is gone.
+
+Bad:
+```ts
+// fix the thing
+await new Promise(r => requestAnimationFrame(() => requestAnimationFrame(r)));
+```
+
+Good:
+```ts
+// Double rAF forces a layout flush before measuring. Single rAF returns stale
+// values on Safari 17. Remove when Safari ≥ 18 is the baseline.
+await new Promise(r => requestAnimationFrame(() => requestAnimationFrame(r)));
+```
+
+The good one names the cause and the removal condition.
+
+### Surprising behaviour
+
+Code that does the right thing but doesn't look like it - code the next reader will be tempted to "fix" because it looks dangerous.
+
+Bad:
+```ts
+// in-place
+normalizeInPlace(buffer);
+```
+
+Good:
+```ts
+// Intentionally mutates the input buffer.
+// Copying doubles memory usage on 2GB+ exports.
+normalizeInPlace(buffer);
+```
+
+The good one tells the next reader "this looks wrong, but here's why it's intentional" - defending the code against a well-meaning later refactor.
+
+## TODO / FIXME / HACK Markers
+
+Every marker carries:
+
+- **Expiry** - a machine-parsable `YYYY-MM-DD` date (`TODO: 2026-09-01 remove after Symfony 7.2`) or a trigger (`TODO: remove after the auth migration ships`). Use the full date so a check can flag past-due markers; a trigger is fine when no date fits.
+- **Issue link** when one exists (`FIXME: #142 retry logic loses events under network partition`).
+- **Owner tag optional** - reserve `TODO(name):` for multi-contributor work. Solo, drop the tag.
+
+Bare markers create future bugs.
+
+Bad: `// TODO: clean this up later.`
+Good: `// TODO: 2026-08-01 remove this fallback once the new auth flow ships.`
+
+The bad one will be there in three years.
+
+## Antipatterns
+
+The next reader can't use these. Don't write them; if you see them while you're already editing the surrounding code, delete or fix.
+
+- **Restating the code.** `i++; // increment i.` The reader can see the increment.
+- **Commented-out code.** Git remembers. Delete.
+- **Tombstones.** `// removed the old caching layer.` The diff records the removal; the comment confuses the next reader.
+- **Archaeological comments.** `// legacy.` `// temporary.` `// migrated from X.` `// new implementation.` Six months on, nobody knows what "new" meant. Explain the current constraint, not the history.
+- **Position references.** `// see function below.` `// the loop above handles X.` Lines and order shift; the reference rots. Refer by symbol name.
+- **Line-number references.** Same rot mechanism - line numbers shift on every edit. Refer by symbol name.
+- **Suppression markers without rationale.** `// eslint-disable-next-line` alone is noise. The rule is the rationale, not the suppression.
+- **Ephemeral task / PR / issue references.** `// fixed in PR #234.` PR numbers age out of useful context. If the link matters, it belongs in the commit message.
+- **Markdown or emoji.** No bold, headers, bullet glyphs, or emoji in code comments - plain prose only. They render as noise in source.
+- **Session artifacts.** `// finally works`, `// as discussed`, `// per the prompt`, `// added during refactor`. Celebratory notes, personal voice, and process narration rot on contact. The comment must stand alone in the repo.
+
+## Special Contexts
+
+**Test code.** Same omit-by-default stance for *inline* comments - the test name carries the why. Carve-outs: regression references (`// reproduces FG-1`), structural markers only when the test body can't encode the setup. If every test has `// arrange / act / assert` labels, extract helpers instead. The doc-comment mandate still applies to test functions per the Verification Gate, but a descriptive test name plus a one-line doc is usually enough.
+
+**Generated code.** A header marking the file as generated is mandatory, not optional:
+
+```text
+// AUTO-GENERATED FROM <source> - DO NOT EDIT
+```
+
+The next maintainer needs to know not to fix bugs in the wrong file.
+
+**Suppression with rationale.** Legitimate pattern. Use the linter's native reason syntax so a checker can verify a reason is present - ESLint puts it after `--` on the directive itself:
+
+```ts
+// eslint-disable-next-line @typescript-eslint/no-explicit-any -- SDK response is dynamically typed at this boundary; narrowing happens in the next call.
+const raw: any = await client.invoke(params);
+```
+
+## Multi-Language Stance
+
+The WHEN and WHY rules above are portable across languages. Core SYNTAX is not - defer to each language's conventions for format, with the house layout conventions from the top of this playbook (tag separator, blank line, line width) layered on top:
+
+- **TypeScript / JavaScript.** JSDoc when documenting contracts; plain `//` inline.
+- **Python.** PEP 257 for docstrings; `#` inline.
+- **Go.** godoc syntax for all identifiers, exported AND private; `//` inline. Go's culture documents only exported names - but this playbook's doc-comment mandate ("Docstring vs Inline") requires one on every unit, so apply the broader rule, not Go's default.
+- **Rust.** rustdoc (`///` and `//!` are doc comments) for all items, public AND private; `//` inline.
+- **Shell.** `#` only. No standardised docstring; put contract details in a heredoc help block at the top of the script.
+
+## Security
+
+Comments ship with the code and get indexed.
+
+Never include in a comment:
+- Secrets, tokens, API keys, anything that authenticates.
+- Customer or patient identifiers, even synthetic-looking ones.
+- Internal-only URLs that reveal infrastructure topology.
+- Production hostnames or account IDs.
+
+If you find any of these in existing comments while editing, redact - don't leave them because they look old.
+
+## Troubleshooting
+
+**A linter rejects the `@param name - desc` / `@returns value - desc` house format** (e.g. eslint-plugin-jsdoc expects a `{type}` or a different shape). Keep the house format and suppress that specific rule with rationale on the line - the description carries the meaning, so don't restate types to satisfy it.
+
+**An existing comment violates the playbook. Rewrite or leave?** Leave, unless you're already editing the surrounding code. The playbook is forward-looking; it doesn't mandate a cleanup pass.
+
+**A comment just restates the code and you're already editing nearby.** Delete it without hesitation - if removing it loses no hidden knowledge (no constraint, invariant, workaround, or surprise), it was never earning its place. `counter++; // increment counter` goes. This applies while you're already in the file; it is not a mandate to sweep the repo.
+
+**A marker has no expiry or issue link.** Flag, don't autofix. The author may have context worth recovering.
+
+**A reviewer wants more *inline* comments than the playbook allows.** Show them the playbook. The omit-by-default stance for inline comments is the project rule, not personal preference. (Doc comments are separate - those are mandatory.)
+
+**An AI agent keeps adding block-by-block comments anyway.** Cite this playbook in the prompt context. The rules only work if the agent has read them.
+
+## Verification Gate
+
+Before claiming a code change is done, walk the new and changed comments against these checks. Each is tagged by the enforcement layer that owns it: **[static]** = mechanical, checkable by a linter; **[judge]** = semantic, for a review-judge or a human reviewer.
+
+1. **[judge] Each INLINE comment satisfies one of the four valid reasons** (hidden constraint, subtle invariant, workaround, surprising behaviour), and when it states a WHY it prefers business/domain/legal/vendor rationale over pure implementation rationale a reader could reconstruct. If you can't name a reason, delete the comment. Doc comments on functions/methods and classes/files are required regardless - this check is for inline comments only.
+2. **[judge] Each comment would survive renaming a variable or reordering functions** in the surrounding code (the Half-Life Test). If a refactor would invalidate it, the content belongs in code, not prose.
+3. **[static] Each TODO / FIXME / HACK marker carries an expiry** (a `YYYY-MM-DD` date or a trigger) and an issue link when one exists. Bare markers are future bugs.
+4. **[static] No comment contains secrets, internal URLs, or production hostnames** (pattern-matchable); customer/patient identifiers may need **[judge]**. Comments ship with the code.
+5. **[judge] Existing comments edited or left untouched are still accurate.** A stale comment from before your edit is now your responsibility if you noticed it.
+6. **[static] presence + [judge] quality: Every function/method and class/file carries a doc comment** - presence, the blank separator line, and the 1-5 (function) / 3-10 (class/file) line counts are mechanical; whether the orientation (when-to-use, big-picture fit, null/edge context, footguns) and the per-parameter/return descriptions are *real* and not restated types is semantic. Required regardless of the inline four-reasons check, which governs inline comments only.
+7. **[static] Each comment line wraps at about 110 characters** - not padded short to 50-70, and not run past 120.
+
+If a comment fails any of these, fix it before merging. This gate is the spec for the two enforcement layers: the **[static]** items map to a linter, the **[judge]** items to a review-judge - keep the tags accurate so the boundary stays clear if those checks are built.

+# Gruff Code Quality
+
+Use this when the user asks to run or fix findings from the gruff static-analysis family: `gruff-go`, `gruff-rs`, `gruff-ts`, `gruff-php`, or `gruff-py`. Gruff is a composite-score code-quality analyzer: it grades quality pillars and emits per-rule findings without executing the code.
+
+**Why gruff exists.** The goal is to force the agent to produce code a human can actually sign off on: legible enough to verify, secure where the eye fails, and tested for real rather than padded with low-signal ceremony. The findings are the lever, not the goal - a doc comment a reviewer can diff against the body, a name that carries intent, a security finding that catches what a reading review misses, a test that asserts behavior instead of just exercising mocks. Each closes the gap between code that *looks* done and code that *is* done; see [`code-comments.md`](./code-comments.md) for the verification-surface principle underneath.
+
+Gruff is not a correctness checker. It does not replace typecheckers, linters, test suites, or maintainer judgment. It also does not know every project convention; a short variable, repeated test setup, or public parameter name may be intentional.
+
+Composite score is a weak cleanup KPI during active work. High-count accepted-debt rules can dominate penalty weight, so report per-rule deltas for APPLY / APPLY-WITH-CHECK clusters instead of treating score movement as proof of progress.
+
+For comment-specific findings, load [`code-comments.md`](./code-comments.md) as the quality bar before editing source comments.
+
+## Gruff at a glance
+
+- **Loop:** measure -> pick one cohesive cluster -> fix the root cause -> rerun gruff on the touched paths -> run the project's normal verify.
+- **The targeted gruff rerun is the reproduction** - never claim a finding fixed from inspection alone.
+- **Fix, don't silence.** Rename, extract, or document to satisfy a finding; never `enabled: false`, and never baseline mid-cleanup.
+- **Triage high-volume rules first** (APPLY / APPLY-WITH-CHECK / CONFIGURE / BASELINE / LARGER-REFACTOR / SKIP-CODEBASE) before editing individual findings.
+- **Doc findings:** load `code-comments.md` as the quality bar - doc comments are mandatory there, so `docs.missing-*` is mostly FIX, not noise.
+- **API safety:** don't rename public/exported names to satisfy a rule; prefer config or accepted debt.
+- Gruff is not a correctness checker - it never replaces typecheck, tests, or judgment.
+
+## Availability Check
+
+Run this before declaring the requested gruff tool unavailable. Set `target` from the requested language; finding any other gruff binary does not satisfy the check.
+
+```bash
+target=gruff-ts  # one of: gruff-go, gruff-rs, gruff-ts, gruff-php, gruff-py
+found=
+for candidate in "vendor/bin/$target" "node_modules/.bin/$target" "$HOME/.local/bin/$target" "$target"; do
+  if [ -x "$candidate" ]; then
+    found="$candidate"
+    break
+  fi
+  if command -v "$candidate" >/dev/null 2>&1; then
+    found="$(command -v "$candidate")"
+    break
+  fi
+done
+test -n "$found"
+"$found" --version
+```
+
+For Node-installed `gruff-ts`, `npx` is also valid:
+
+```bash
+npx gruff-ts --version
+```
+
+Then confirm the command surface for the specific tool before relying on flags. The examples below are illustrative; substitute the target binary and verify the installed tool before assuming another gruff family member or release supports the same subcommands or flags.
+
+```bash
+gruff-ts --help
+gruff-ts analyse --help
+gruff-ts summary --help
+gruff-ts dashboard --help
+gruff-ts report --help
+gruff-ts list-rules --help
+gruff-ts list-rules --format json
+```
+
+If the requested gruff binary fails because the package cannot be fetched or executed, do not invent findings. Fall back to the project's normal lint, typecheck, and test commands, and report that gruff itself could not run.
+
+## Tool vs Target
+
+When a request names a path or project, classify it before reading deeply:
+
+- **TOOL:** the named path is a gruff checkout, package, binary, or CLI reference to run against the current target.
+- **TARGET:** the named path is the codebase the user wants scanned or fixed.
+
+Parse "use X to find/check/analyse Y" as "invoke X against Y" when X is tool-shaped: it has a `bin` entry, executable wrapper, CLI README, or lives outside the current working tree. If both readings remain plausible after checking the README/package metadata, ask whether X is the tool or the target before drafting plans or editing files.
+
+## Intent
+
+Use gruff to guide a tight code-quality loop:
+
+1. Measure the current findings.
+2. Pick one cohesive cluster.
+3. Fix root causes, not symptoms.
+4. Rerun gruff on the touched paths.
+5. Run the project's normal verification for the changed behavior.
+
+Gruff output is input to engineering judgment. A finding may point at a real defect, a naming smell, an under-documented contract, or an analyzer limitation. Treat each finding as a question to answer in code, comments, or tests.
+
+The tools share the same broad purpose across languages, but do not assume every rule id, flag, severity, or false-positive escape hatch is identical. Confirm the installed tool's `--help` and `list-rules` output before writing language-specific claims.
+
+## Command Selection
+
+Use the smallest command that answers the current question. Examples use `gruff-ts`; substitute the target binary.
+
+```bash
+gruff-ts summary
+gruff-ts summary src/
+gruff-ts analyse src/payments/charge.ts
+gruff-ts analyse --diff working-tree
+gruff-ts analyse --format json src/payments/charge.ts
+gruff-ts list-rules
+```
+
+Use `summary` for orientation when the installed tool provides it. If it does not, use `analyse --format json` plus a local summarizer. Use `analyse <path>` while fixing a file or cohesive cluster. Use `dashboard` only when the tool exposes it and a browsable view helps the user inspect findings. Use `--diff working-tree` when the installed tool supports it and the user wants changed-code focus. Use JSON when you need complete output, grouping, scripting, or exact counts.
+
+Do not run broad gruff scans in a loop when a targeted path would answer the question. Broad scans are useful at the start and end; targeted scans are useful during fixes.
+
+## JSON-First Triage
+
+For large reports, use JSON before editing:
+
+```bash
+gruff-ts analyse --format json <paths> > /tmp/gruff-findings.json
+```
+
+Inspect the schema before scripting against it:
+
+```bash
+python3 - <<'PY'
+import json
+
+with open("/tmp/gruff-findings.json", encoding="utf-8") as handle:
+    report = json.load(handle)
+
+print("top-level keys:", sorted(report.keys()))
+findings = report.get("findings")
+if not isinstance(findings, list):
+    raise SystemExit("No list-valued findings field; inspect the JSON before scripting.")
+print("findings:", len(findings))
+print("first finding:", findings[0] if findings else None)
+PY
+```
+
+Then group by rule, file, and pillar. A tiny helper is enough after the schema check:
+
+```python
+import json
+from collections import Counter
+
+with open("/tmp/gruff-findings.json", encoding="utf-8") as handle:
+    report = json.load(handle)
+
+findings = report.get("findings")
+if not isinstance(findings, list):
+    raise SystemExit("No list-valued findings field; inspect this gruff version's JSON schema.")
+
+rule_ids = Counter(
+    finding.get("ruleId", "<missing-ruleId>")
+    for finding in findings
+    if isinstance(finding, dict)
+)
+
+for rule_id, count in rule_ids.most_common():
+    print(f"{count:5d}  {rule_id}")
+```
+
+Do not assume the JSON schema from memory. Verify fields such as `ruleId`, `severity`, `pillar`, `confidence`, `symbol`, or `metadata` on the installed version.
+
+## Triage
+
+Sort findings by likely maintenance value, not by easiest suppression:
+
+1. Correctness or security findings that can change runtime behavior.
+2. Modernisation findings that remove unsafe or obsolete current-language idioms.
+3. Naming findings where better names make comments unnecessary.
+4. Documentation findings on exported APIs, side effects, invariants, thresholds, and error behavior.
+5. Complexity findings when a small extraction reduces real branching risk.
+6. Test-quality findings when the test currently hides behavior, overfits implementation, or is hard to extend.
+
+Keep one cluster small enough to verify. A good cluster is "one file", "one rule family across adjacent files", or "one public contract plus its tests". Avoid mixing unrelated gruff categories just because they appear in the same global report.
+
+For high-volume rules, classify the rule before editing individual findings:
+
+| Category | Meaning | Action |
+|---|---|---|
+| APPLY | Findings are true positives for this codebase. | Fix the cluster in small batches. |
+| APPLY-WITH-CHECK | Rule is useful but has false positives. | Sample findings and verify each edit. |
+| CONFIGURE | Rule is right but the project uses accepted vocabulary or thresholds. | Tune config with comments explaining why. |
+| BASELINE | Remaining findings are accepted debt. | Baseline only after cleanup, with notes. |
+| LARGER-REFACTOR | Finding is real but needs a larger refactor. | Report it; do not smuggle a refactor into cleanup. |
+| SKIP-CODEBASE | Rule conflicts with a deliberate project convention. | Document the decision and avoid churn. |
+
+Decision tree:
+
+- Real defect or clear maintainability win -> APPLY.
+- Useful rule with false positives -> APPLY-WITH-CHECK.
+- Accepted project vocabulary, abbreviation, or threshold -> CONFIGURE with a rationale comment in config.
+- Accepted debt after cleanup -> BASELINE with notes, never mid-cleanup.
+- Deliberate convention and no config hook -> SKIP-CODEBASE.
+- Correct finding but multi-day fix -> LARGER-REFACTOR.
+
+Before CONFIGURE or BASELINE, write down the policy decision. Broad allowlists and baselines are not routine cleanup.
+
+```text
+Rule:
+Action: CONFIGURE | BASELINE
+Sampled findings:
+Why these findings are accepted:
+Config or baseline file:
+Notes file, when baselining:
+Approval status:
+Revisit trigger or expiry:
+```
+
+## Fix Loop
+
+For each cluster:
+
+1. Read the relevant source and nearby tests before editing.
+2. If a Rewrite-First fix (rename, extract, or simplify) can remove the need for a comment, do that first, per [`code-comments.md`](./code-comments.md).
+3. Patch the code.
+4. Run `<gruff-binary> analyse <touched paths>`.
+5. If findings remain, decide whether the remaining issue is real, out of scope, or better handled in a later cluster.
+6. Run the language's compile/typecheck step, lint, and focused tests appropriate to the changed paths.
+7. Record any repeated gruff lesson, footgun, or pattern with real evidence when verification catches a failure or the workflow changes.
+
+Stop a cluster when the targeted gruff rerun is clean, or when every remaining finding is explicitly categorized as CONFIGURE, BASELINE, LARGER-REFACTOR, or SKIP-CODEBASE. Never claim a gruff finding is fixed from inspection alone. The targeted gruff command is the reproduction for analyzer findings.
+
+## Reading Rule Source
+
+Before fixing a high-volume, surprising, or potentially breaking rule, read the rule implementation for the installed tool. Locate it from the package manager layout, not from memory. Common starting points:
+
+- PHP: `vendor/blundergoat/gruff-php/src/Rule/<Pillar>/<RuleName>Rule.php`, optional `RuleHelper.php`, and shared helpers such as `vendor/blundergoat/gruff-php/src/Rule/TestQuality/TestQualityNodeHelper.php`.
+- TypeScript: `node_modules/@blundergoat/gruff-ts/` or the package source for the installed version.
+- Go: `$(go env GOMODCACHE)/github.com/blundergoat/gruff-go@*/` when installed as a module/tool.
+- Rust: `~/.cargo/registry/src/*/gruff-rs-*/` or the tool checkout used to install it.
+- Python: the environment's `site-packages/gruff_py/`; use `python -m pip show gruff-py` or the project's package manager to locate it.
+
+Look for default options, built-in type/name lists, skip conditions, metadata variants, helper predicates, and the AST or test-scope walker. Those reveal supported config knobs and false-positive escape hatches. If the rule source is unavailable, sample more findings and be conservative with automated edits.
+
+## Known Rule Mechanics
+
+These are starting points from prior gruff cleanup work, not universal law. Verify against the installed rule source before applying them at scale.
+
+For analyzer-shape recipes such as callable rewrites or intentional silent-catch markers, require proof before editing: show the target value is the expected type, run focused behavior checks when runtime behavior can change, and leave a rationale that makes the code clearer or safer for a maintainer. Do not apply these patterns only because they silence a finding.
+
+| Tool | Rule or shape | Mechanic to remember |
+|---|---|---|
+| gruff-php | `naming.parameter-type-name` | `ignoredParameterNames` filters parameters, not local `$x = new Type()` assignments. Locals need rename, restructuring, or accepted debt. |
+| gruff-php | `naming.parameter-type-name` duplicate expected names | Descriptive variants can pass when they contain the expected token sequence and add extra distinguishing tokens. |
+| gruff-php | `test-quality.mystery-guest` / conditional logic | Rules may walk only PHPUnit test scopes. Extract I/O or branching into a meaningful private helper when that improves test signal. |
+| gruff-php | `test-quality.mock-without-expectation` | `createMock` -> `createStub` may lower severity but does not clear the finding. Add verification or accept. |
+| gruff-php | `test-quality.mock-only-test` | Mock expectation chains may not count as assertions. Use capture-spy plus real assertions, or assert an externally observable result. |
+| gruff-php | `security.dangerous-function-call` | `$callable()` -> `$callable->__invoke()` can clear closure/object invocations because the rule shape differs. Safe only when the value is invokable. |
+| gruff-php | `security.silent-catch` | Empty/comment-only catches are detected. Add a real no-op such as `unset($exception)` with a rationale comment if swallowing is intentional. |
+| gruff-php | `security.sensitive-data-logging` | Identifier regexes can flag OpenTelemetry `inputTokens`/`outputTokens`; treat as false positives when they are metrics, not auth tokens. |
+| gruff-php | `sensitive-data.high-entropy-string` | Long MIME types and rule path strings can fire with no useful rewrite. Prefer accept/baseline over string-splitting. |
+| gruff-php | PHPStan scaffolds | `waste.redundant-variable` can hit variables that anchor `/** @var */` narrowing. Check adjacent lines before inlining. |
+| gruff-php | `modernisation.readonly-property-candidate` | Append mutations such as `$this->items[] = ...` may be missed. Grep writes before adding `readonly`. |
+| gruff-php | `docs.missing-constant-phpdoc` | A `//` line above a constant may not count; use the docblock shape the rule expects. |
+| gruff-ts / gruff-go / gruff-rs / gruff-py | language-specific rule names | Fill this table only after checking that tool's `list-rules` and rule source. Do not copy PHP mechanics across languages. |
+
+## Public API Safety
+
+Gruff naming fixes can break callers even when tests pass. Classify the symbol before renaming:
+
+| Position | Usually safe to rename? | Notes |
+|---|---:|---|
+| Local variable | Yes | Still grep the old name after batch renames. |
+| Closure or callback parameter | Usually | Check framework conventions and inferred callback contracts. |
+| Private method parameter | Usually | Safe inside one class after typecheck/tests. |
+| Test helper parameter | Usually | Keep failure messages readable. |
+| Protected method parameter | Maybe | Subclasses and named-argument callers may depend on the name. |
+| Public method or constructor parameter | No by default | PHP named arguments, TS declaration consumers, and docs can depend on it. |
+| Interface or exported callback parameter | No by default | Implementers and callers may both be affected. |
+| Exported object property or serialized field | No by default | Wire formats and dashboard/test fixtures often depend on names. |
+
+If a public name is ugly but stable, prefer config, allowlist, or accepted-debt documentation over a breaking rename.
+
+Language footnotes:
+
+- PHP and Python public parameter names are caller-visible through named arguments.
+- TypeScript exported declarations, object fields, and serialized shapes are the common breaking surface.
+- Go parameter names are usually not API; exported identifier names and struct fields are.
+- Rust free-function parameter names are usually not API, but public struct fields, enum variants, trait contracts, and generated docs matter.
+
+## Documentation Findings
+
+Documentation findings should produce maintainable comments, not analyzer bait. Use [`code-comments.md`](./code-comments.md) and write comments that explain the hidden contract. A `docs.missing-*` fix is not about satisfying the analyzer - the doc comment is a verification surface: it states the intent a reviewer can diff against the body, and a promise the code doesn't keep is exactly the mismatch the bar exists to catch.
+
+`code-comments.md`'s omit-by-default stance is about *inline* comments - it never licensed skipping `docs.missing-*`. Doc comments are mandatory there, so a missing one is a real gap, and the bar is "do not restate syntax," not "write fewer comments." A useful doc comment describes caller obligation, edge values, side effects, errors, determinism, compatibility, or rationale. If a language's ecosystem consumes tags, keep accurate tags; and give every `@param`/`@returns` a real description - if a tag only restates the type signature, rewrite it with meaning (units, edge values, caller obligation) rather than dropping it, per [`code-comments.md`](./code-comments.md).
+
+Gruff documentation rules often need explicit vocabulary near the declaration:
+
+- Error behavior: say whether the function throws, returns a fallback, reports a finding, logs, exits, or swallows an error.
+- Side effects: name what changes, such as filesystem writes, process state, network calls, mutation of an argument, local scanner cursor, or local accumulator.
+- Thresholds: explain the limit, cap, budget, default, or compatibility reason near the number.
+- Complex code: say why the shape exists: compatibility, invariant, tradeoff, performance, determinism, or ordering constraint.
+- Public APIs: describe caller-visible contract, not the body line-by-line.
+- Parameters and returns: keep tags accurate; delete stale tags when signatures change.
+
+Language conventions matter:
+
+- TypeScript: prefer JSDoc/TSDoc; give every `@param`/`@returns` a real description (not a type-only restatement of the signature), per `code-comments.md`.
+- PHP: PHPDoc tags may be part of local static-analysis and IDE contracts; verify project convention before deleting tags.
+- Go: all identifiers, exported and internal, need godoc comments per `code-comments.md` - not just exported ones.
+- Rust: use rustdoc `///` or `//!` for items (public and internal) and keep parameter facts in the type signature when possible.
+- Python: use PEP 257 docstrings for caller-visible contracts and type hints for type facts.
+
+Bad:
+
+```ts
+/**
+ * Handles paths.
+ *
+ * @param paths - a string array of paths
+ * @returns a string array
+ */
+function collect(paths: string[]): string[] {
+  return paths.filter(Boolean);
+}
+```
+
+Good:
+
+```ts
+/**
+ * Return only user-supplied paths that can be checked by the audit.
+ *
+ * Empty strings are ignored here because setup prompts may emit optional
+ * fields as blank lines; callers still receive the original ordering.
+ *
+ * @param paths - raw path list from setup prompts; may contain blank entries
+ * @returns the non-empty paths - original input order preserved
+ */
+function collectAuditPaths(paths: string[]): string[] {
+  return paths.filter(Boolean);
+}
+```
+
+The Bad version pairs a vague summary with type-only tags (`a string array of paths` just restates `string[]`); the Good version's tags add what the signature can't show - provenance, blank-entry handling, and preserved order. A type-only tag fails the bar as surely as a missing one.
+
+Do not add `contract:` prefixes or other marker words as a substitute for meaning. If gruff still reports the comment, improve the comment around the real boundary the rule is asking for.
+
+### docs.missing-internal-function-doc under the mandatory-doc rule
+
+This rule fires on every internal helper that lacks a leading maintainer comment. Under [`code-comments.md`](./code-comments.md)'s mandatory-doc rule - every function/method carries a doc comment - these findings are mostly genuine, not noise: the helper is missing a contract it is required to have. Default response is FIX, not suppress.
+
+Triage `docs.missing-internal-function-doc`:
+
+1. **FIX (default)** - add the doc comment `code-comments.md` requires. A trivial, name-clear helper gets a single tight contract line; a helper hiding a non-obvious WHY (tradeoff, workaround, threshold rationale, side effect, caller obligation) gets that orientation too. Both satisfy the rule.
+2. **RENAME first where it helps** - a better name (`phaseFor` over `processItem`) makes the required doc comment shorter, per the "Rewrite First" ladder. Renaming does not remove the requirement: the mandate stands regardless of name clarity.
+3. **Never baseline `docs.missing-*` as accepted noise** - under the mandate there is no name-clear-helper tail to write off; those get a one-line doc comment too. Do not set `enabled: false`, and do not baseline these away to dodge the work - satisfy them.
+
+Test functions are the one carve-out: under the mandate they still need a doc comment, but a descriptive test name plus a single line is enough (per `code-comments.md`'s "Test code" note) - don't expand test helpers into full contract blocks just to clear the finding.
+
+## Naming Findings
+
+Fix naming findings by making the code carry meaning:
+
+- First decide whether the rule is identifying a readability issue, an accepted project abbreviation, or a breaking API change.
+- Rename booleans to `is`, `has`, `can`, `should`, `does`, `did`, `was`, `will`, `may`, `in`, `supports`, or `requires` shapes unless the project config says otherwise.
+- Replace short or placeholder names with domain names: `finding`, `agentFacts`, `renderedLine`, `instructionPath`.
+- Avoid generic functions such as `process`, `handle`, `run`, or `execute` when the body has a domain verb available.
+- Prefer one casing for acronyms in a file.
+
+Many naming rules expose options such as accepted abbreviations, ignored parameter names, or threshold lists. For project vocabulary, a documented config entry is often better than fighting the same finding one symbol at a time.
+
+After a rename, grep the old identifier and run the language's compile/typecheck step. Gruff naming cleanup can cross declarations, test fixtures, serialized payloads, and dashboard or generated contexts.
+
+Do not mass-rename public API parameters or exported object fields to satisfy a naming rule. First decide whether the rule is a real readability issue, an accepted project abbreviation, or a breaking API change.
+
+## Complexity Findings
+
+Complexity findings are not an automatic refactor order. First identify why the function is complex:
+
+- Many independent validation branches may be clearer as named checks.
+- Rendering functions may be complex because they preserve a public text format.
+- Parsers may need explicit branches for compatibility.
+- Large test setup may need fixture helpers only if the helpers make assertions clearer.
+
+Refactor only when the extraction reduces real maintenance risk. If public output shape, ordering, or compatibility forces explicit branches, document that reason and leave deeper refactoring for a scoped change.
+
+## Modernisation Findings
+
+Modernisation findings point at safer or clearer current-language idioms. Do not apply a TypeScript rewrite to PHP, Go, Rust, or Python code just because this playbook names it.
+
+Examples by language:
+
+- TypeScript: replace unsafe non-null assertions with guards, prefer `??` when valid falsy values must survive, and add rationale to `@ts-ignore` / `@ts-expect-error`.
+- PHP: verify constructor promotion, enum conversion, readonly properties, and callable rewrites against PHPStan and mutation sites.
+- Go: check whether the finding maps to current standard-library idioms, error handling, or deprecated package use.
+- Rust: check whether the finding maps to current control-flow or error-propagation idioms before changing public types.
+- Python: check whether the finding maps to current typing, f-string, context-manager, or pathlib idioms.
+
+Run the language's compile/typecheck step after these fixes. Modernisation changes can alter narrowing and public types even when runtime behavior looks unchanged.
+
+## Generic Type Narrowing
+
+Generic-soup types are a cross-language modernisation pattern. Narrow them when the boundary contract is known:
+
+| Language | Broad type | Better target |
+|---|---|---|
+| PHP | `mixed` | JSON unions such as `array<array-key, mixed>|bool|float|int|string|null`, or a domain DTO. |
+| TypeScript | `any` | `unknown` plus narrowing, discriminated unions, or concrete interfaces. |
+| Go | `interface{}` / `any` | Concrete types, type parameters, or explicit tagged structures. |
+| Rust | `Box<dyn Any>` / broad `serde_json::Value` | Concrete types, enums, or narrow deserialization structs. |
+| Python | `typing.Any` | Concrete annotations, `Optional[...]`, `Union[...]`, protocols, or typed dicts. |
+
+Always run the language type checker after narrowing; callers may pass a variant the first replacement missed.
+
+## Test-Quality Findings
+
+Treat test-quality findings as questions about signal:
+
+- Is the test asserting behavior or implementation detail?
+- Does setup hide the production path?
+- Is a magic assertion number a real domain constant that deserves a name?
+- Would a fixture helper clarify the test, or would it hide the key behavior?
+- Is a loop in a test masking which case failed?
+
+Do not blindly abstract test setup. A little explicit setup is often better than a helper that makes the failing contract invisible.
+
+Never add no-op helpers, fake SUT calls, or meaningless wrappers just to satisfy a test-quality heuristic. Extraction is valid only when it improves the test's signal: clearer setup, isolated I/O, reusable fixtures, or a more direct assertion.
+
+When a mock-expectation test is flagged as assertion-free, treat the warning as "no explicit assertion call found" - some gruff rules count only explicit assertion calls. To clear without weakening the test, capture collaborator arguments in a spy/callback and assert them outside the mock, or assert an externally observable return value/state.
+
+## Mechanical Patterns
+
+Use mechanical edits only after the rule and symbol class are safe.
+
+| Pattern | Recipe | Guardrail |
+|---|---|---|
+| Word-boundary rename | PHP: `r'\$' + re.escape(old) + r'\b'`; TS/Go/Rust/Python: `r'\b' + re.escape(old) + r'\b'`. | Never plain string-replace; `$auth` must not rewrite `$author`. |
+| Per-test data helper | Move inline arrays, literals, or setup objects into a named helper such as `dataForInvalidToken()` or `transportReturning(body, status)`. | Helper must make the test clearer, not merely reduce line count. |
+| Multi-new setup | Collapse repeated mock/transport/SUT construction into a factory helper with domain parameters. | Keep the SUT call and assertions visible in the test body. |
+| Real lightweight implementation | Prefer a small real PSR-17 or framework implementation over four mocks when the real object is stable and cheap. | Do not introduce integration behavior into a unit test by accident. |
+
+## Anti-Patterns to Refuse
+
+- Empty helpers such as `arrange()` that exist only to increase call counts.
+- Wrappers such as `array_merge([], $literal)` that exist only to look like a SUT call.
+- Public DTO/property/parameter renames that break callers just to satisfy naming rules.
+- Mid-cleanup baseline generation to make current findings disappear.
+- `createMock` -> `createStub` conversions presented as clearing `mock-without-expectation` when the finding remains.
+- Splitting standard MIME types, paths, or rule identifiers into concatenated strings to dodge entropy checks.
+
+## Baselines and Reports
+
+Use baselines only when the user asks for debt tracking or when a project already has a gruff baseline workflow:
+
+```bash
+<gruff-binary> analyse --generate-baseline .gruff-baseline.json
+<gruff-binary> analyse --baseline .gruff-baseline.json
+```
+
+Do not generate a baseline mid-cleanup. That captures true positives and noise together. Generate or update a baseline only after the remaining findings are deliberately accepted debt, and keep a sibling notes file explaining why the debt is accepted.
+
+Use reports when the user needs an artifact:
+
+```bash
+<gruff-binary> report --format html --output .goat-flow/logs/quality/gruff-report.html
+<gruff-binary> report --format json --output .goat-flow/logs/quality/gruff-report.json
+```
+
+Reports are evidence. They do not replace source edits, tests, or focused analyzer reruns.
+
+## Progress Reporting
+
+Report targeted deltas, not just the composite score. Composite scores can barely move when high-count accepted rules dominate the penalty.
+
+Use this shape:
+
+```text
+Rule cluster fixed:
+- tool: gruff-ts <version>
+- docs.missing-error-behavior-doc: 12 -> 0 on src/payments
+- naming.short-variable: 9 -> 1 on test helpers
+
+Remaining accepted/larger-refactor:
+- complexity.npath in renderTextOutput: real but needs separate renderer refactor
+- naming.* public API params: skipped to avoid BC break
+```
+
+For regression tracking, compare stable tuples such as `(ruleId, file, symbol)` instead of trusting line-number-only diffs; line shifts can make old findings look new.
+
+## Quick Reference
+
+| Finding shape | Default response |
+|---|---|
+| `naming.*` on local/private symbols | Word-boundary rename, then grep old name and typecheck. |
+| `naming.*` on public API params or exported fields | Prefer config/allowlist/accepted debt unless a breaking change is approved. |
+| `test-quality.*` reading I/O in the test body | Extract meaningful I/O fixture/helper; keep assertions visible. |
+| `test-quality.*` conditional logic in the test body | Extract setup policy only when the test reads clearer afterward. |
+| `test-quality.mock-without-expectation` | Add real verification or accept; `createStub` may not clear it. |
+| `test-quality.mock-only-test` | Capture-spy plus explicit assertion, or assert observable SUT output. |
+| `security.silent-catch` | Add a real statement plus rationale if swallowing is intentional. |
+| `security.dangerous-function-call` on PHP `$x()` | Use `$x->__invoke()` only when the value is known invokable. |
+| insecure random APIs | Use the language's secure random primitive unless the rule source documents a safe escape hatch. |
+| sensitive-data false positives on metrics names | Accept/configure with evidence; do not break public telemetry names. |
+| high-entropy MIME/path/rule strings | Accept or baseline with notes; do not reduce readability to game entropy. |
+| size/complexity/god-function findings | LARGER-REFACTOR unless a small extraction clearly reduces risk. |
+
+## Verification Gate
+
+Before claiming gruff work is done, show current-session evidence for the universal gates:
+
+- Targeted gruff rerun on every touched source cluster.
+- Compile/typecheck for the edited language: examples include PHPStan/Psalm, `tsc`, `go test`/`go vet`, `cargo check`/`cargo clippy`, mypy/pyright.
+- Focused tests for behavior or fixture changes.
+- Lint or formatter checks when code style changed.
+- Existing project linter configs checked before overriding gruff findings; when project lint explicitly allows a pattern, decide CONFIGURE/SKIP-CODEBASE rather than churn.
+
+Project-specific anti-pattern scans may also apply: run any comment-marker scans, learning-loop, or housekeeping checks your project defines after the fix, so analyzer-driven edits don't reintroduce a banned pattern.
+
+## Troubleshooting
+
+**Gruff says a comment is missing, but there is already a comment.** The comment may be attached to the wrong declaration, may restate the symbol, or may omit the rule's required boundary. Rewrite it around caller-visible contract, side effect, error behavior, invariant, or threshold rationale.
+
+**Gruff reports complexity but the function is public-output rendering.** Check whether extraction would make the output contract easier to break. If explicit branches preserve ordering or compatibility, document that contract and leave structural refactoring to a dedicated change.
+
+**Gruff reports naming after a rename.** Grep for the old name and check generated, ambient, fixture, and serialized surfaces. TypeScript may compile while a dashboard VM test or JSON fixture still expects the old shape.
+
+**The global summary still looks bad after the cluster is fixed.** Report both the global state and the targeted state. A cluster can be clean while unrelated debt remains.
+
+**`analyse` exits non-zero with no findings and an error mentioning `schemaVersion`.** Recent gruff releases require a `schemaVersion:` line at the top of the project config (`.gruff-<lang>.yaml`); without it `analyse` fails closed instead of scanning, so any wrapper that only reads `.findings` sees empty or non-JSON output. The error names the expected value (for example `gruff-ts.config.v0.1`). Fix by regenerating the config: `gruff-<lang> init --force` rewrites it with the required `schemaVersion` while preserving your existing `paths.ignore` and severity entries (plain `init` refuses to overwrite an existing file). Do not hand-invent the version string or strip the field - run `init` so the value matches the installed binary.

 - **Incremental result cache** - cache-eligible runs (those with no project rules — e.g. the `security` profile, or a config that excludes the design/dead-code rules) now reuse unchanged files' findings across runs via a content-addressed, gitignored `.gruff-cache/`, keyed on file bytes plus the resolved rule settings plus the gruff version. A cold cache and `--no-cache` produce byte-identical output; any content, config, or version change invalidates the affected entries; runs with project rules bypass the cache entirely (their cross-file rules need every unit). The base-ref snapshot cache for `--diff-vs` is a documented follow-up (ADR-020).
 - **Config presets and `extends:`** - bundled `gruff.recommended`, `gruff.starter`, and `gruff.strict` profiles plus an `extends:` key let a repo replace a ~560-line `.gruff-php.yaml` with a few lines — `extends: gruff.recommended`, then only your overrides. `extends:` accepts a bundled preset name (`gruff.*`) or a relative/absolute path; chains resolve ancestor-first (a child's section overrides the inherited one), cycles and chains deeper than five hops fail with a clear error naming the chain, and an unknown preset name lists the valid ones. `extends: gruff.recommended` with no overrides behaves identically to running with no config file at all, and a preset-integrity test keeps the bundled presets from drifting out of sync with the rule registry (ADR-021).
 - **BREAKING: Retired the `complexity.npath` rule** - NPath produced false positives on sequential-but-simple branching and is redundant with the cognitive, cyclomatic, and nesting metrics. Remove any `complexity.npath` block from your config (it now fails closed as an unknown rule id) and regenerate baselines to drop stale npath findings. The registry now exposes 118 rules.
+- **BREAKING: Retired the synthetic `design.god-method` rubric** - Size and complexity findings remain visible and scored through their native pillars, but gruff no longer appends a second design finding when they overlap on the same symbol. Remove stale `design.god-method` entries from baselines; there is no config block to migrate because the old finding was not registry-backed. The registry count is unchanged because the old finding was never registry-backed.
 - **Complexity recalibration** - `complexity.halstead-volume` and `complexity.maintainability-index` are now `advisory` (informational, non-gating); `complexity.cognitive` tightened to a threshold of 20 and `complexity.nesting-depth` to 4; `complexity.cyclomatic` is now `warning`. The complexity pillar now gates on the metrics that track human comprehension rather than branch-counting proxies.
 - **Test-quality gate parity** - the "tested for real" mission leg now gates. `test-quality.no-assertions` (a test with no observable assertion), `test-quality.sut-not-called` (the named subject is never invoked), and `test-quality.tautological-type-assertion` (`assertInstanceOf(X, new X)`) are promoted to `error`, so `analyse --fail-on error` fails a suite whose tests prove nothing — and the cheapest way to satisfy each is a real assertion. The cosmetic-fix and style smells (`mock-without-expectation`, `trivial-assertion`, `eager-test`, naming/readability, …) stay at warning/advisory so the gate never forces ceremony. Each promotion fires only on genuinely fake tests, not on assertion helpers, data-provider matrices, `expectException`, or Pest `expect()` (ADR-022).
 - **Config accepts `advisory` severity** - the `rules.<id>.severity` config key now accepts `advisory` alongside `warning` and `error`, so rules that default to advisory can be pinned or overridden in `.gruff-php.yaml`.
 - **Mission documented** - a stated project mission (governing AI-generated code for human verifiability) now anchors `README.md`, `docs/mission.md`, and the agent instructions, recorded in ADR-017.
 - **Nullable JSON-boundary bags exempt from `phpdoc-mixed-overuse`** - `modernisation.phpdoc-mixed-overuse` no longer fires on a nullable unstructured bag such as `array<string, mixed>|null` — the honest type of a `json_decode` helper that returns the decoded object or `null` — matching the existing exemption for the non-null `array<string, mixed>` form. Standalone `mixed` and concrete-keyed shapes still fire.
-- **Clean self-scan** - gruff-php's own source now passes `gruff-php analyse` with zero unsuppressed findings: the `AnalyseCommand` god-object is decomposed into `AnalysisFindingSupport` and `BranchReviewBuilder` collaborators, the `--no-cache` flag moves onto `AnalyseCommandOptions`, and the `FailThresholds` / `SourceDiscovery` hotspots drop below the cognitive-complexity gate. No CLI behaviour or output schema changes.
+- **Internal restructuring** - the `AnalyseCommand` god-object is decomposed into `AnalysisFindingSupport` and `BranchReviewBuilder` collaborators, the `--no-cache` flag moves onto `AnalyseCommandOptions`, and the `FailThresholds` / `SourceDiscovery` hotspots drop below the cognitive-complexity gate. No CLI behaviour or output schema changes.
+- **Restored `docs.return-comment`** - the documentation rule requiring a one-line comment directly above every `return` is back in the catalogue (advisory). A comment naming *why* an exit returns is a verification surface a reviewer diffs against the code; it was previously retired as ceremony, which mis-read its purpose for a coding-agent hook. `docs.continue-comment` stays retired. The registry now exposes 119 rules.
+- **`docs.missing-param-tag` now covers non-public methods** - the rule previously inspected only public methods; it now flags any documented method or function (private and protected included) whose docblock omits an `@param` for a parameter, matching the project's mandatory-doc-on-every-unit stance. Freeze existing private-method gaps via the baseline so the rule gates new code rather than forcing a backfill.

+# ADR-024: Cluster correlated size/complexity penalties
+
+**Status:** Accepted
+**Date:** 2026-05-31
+**Author(s):** Matthew Hansen
+**Builds on:** ADR-023 (retired the synthetic `design.god-method` composite).
+
+## Context
+
+The cross-port design principle P5 says: when several findings describe one root
+cause — a method that is long *and* deeply nested *and* cyclomatically complex —
+score it once, while still listing every finding in the report. Billing one
+root cause four times distorts the grade and tells the agent the file is four
+times worse than it is, pushing disproportionate rewrites for a single problem.
+
+`ScoreCalculator` did not cluster. `pillarScores()` and `fileScores()` each
+summed `penaltyFor()` over their findings independently, so a single over-large
+method subtracted a separate penalty for every size and complexity finding it
+produced — once in the Size pillar, again (twice or three times) in the
+Complexity pillar, and the full stack again in its file score. ADR-023 retired
+the `design.god-method` composite that used to *add* a third pillar's penalty on
+top of that, but retiring the composite alone left the underlying size and
+complexity findings still double- and triple-counting. Closing P5 requires
+clustering those real findings, not just removing the synthetic one.
+
+The sibling ports already converged on the same mechanism: gruff-ts (ADR-009)
+and gruff-py (ADR-016) group findings that share a `file + symbol + line` and let
+the group contribute a single penalty while keeping every finding visible.
+gruff-py's `_finding_penalties` (penalty = `max(member) / len(group)`) is the
+reference this port mirrors for cross-port parity.
+
+## Decision
+
+Cluster correlated complexity/size penalties in `ScoreCalculator`, keeping every
+finding in the report.
+
+- Group scored findings by `(file, symbol, line)` — the same key tuple the
+  fingerprint uses — but only when the finding's rule is in the correlated set
+  `{complexity.cognitive, complexity.cyclomatic, complexity.nesting-depth,
+  size.method-length, size.parameter-count}`. A finding with no symbol or no line
+  never clusters.
+- A cluster of two or more contributes one shared weight per member:
+  `max(member base penalty) / member count`. The largest symptom sets the bill;
+  the weaker overlapping symptoms divide into it rather than stacking on top.
+- Lone findings, and any rule outside the correlated set (naming, docs, security,
+  …), keep their full base penalty even when they land on the same symbol.
+- The shared weight follows each finding into both the pillar and the file
+  penalty buckets, so the two views agree.
+- Every finding stays in the detailed report and in its pillar's finding count;
+  only the scoring weight is divided. The report's score explanation now states
+  that correlated findings on one symbol share a single penalty.
+
+The correlated set deliberately omits `design.god-method`: it was retired in
+ADR-023 and emits nothing to cluster.
+
+## Failure Mode Comparison
+
+| Option | What fails | Why rejected or accepted |
+| --- | --- | --- |
+| Keep summing every finding independently | One god-method is billed up to four times; the grade says the file is far worse than it is and the agent over-rewrites one root cause. | Rejected. This is the confirmed P5 gap. |
+| Re-add a composite that carries a neutral score | Reintroduces the non-registry finding ADR-023 removed and its bespoke scoring branch, for no remediation value. | Rejected. The composite was the disguise; clustering is the mechanism. |
+| Drop all but one finding per cluster from the report | Loses the per-symptom detail (which of length / nesting / branching is worst) the agent needs to fix the right thing. | Rejected. P5 requires keeping every finding visible. |
+| Cluster by `file + symbol + line`, one max/count penalty, keep all findings | Two findings on different lines of one method do not cluster (acceptable: they are distinct sites). | Accepted. Mirrors gruff-py/gruff-ts; one root cause, one penalty, full detail. |
+
+## Consequences
+
+- Composite and pillar grades rise for files that previously double- or
+  triple-counted an over-large method; a file with no co-located cluster scores
+  exactly as before. Scores are still deterministic.
+- Findings, fingerprints, and the `gruff.analysis.v2` / `gruff.baseline.v1`
+  schemas are unchanged: clustering changes only penalty weighting, never the
+  finding set or its identities, so baselines keep matching by fingerprint.
+- The score `explanation` string changes to describe the clustering; reporters

 - **Config presets and `extends:`** - bundled `gruff.recommended`, `gruff.starter`, and `gruff.strict` profiles plus an `extends:` key let a repo replace a ~560-line `.gruff-php.yaml` with a few lines — `extends: gruff.recommended`, then only your overrides. `extends:` accepts a bundled preset name (`gruff.*`) or a relative/absolute path; chains resolve ancestor-first (a child's section overrides the inherited one), cycles and chains deeper than five hops fail with a clear error naming the chain, and an unknown preset name lists the valid ones. `extends: gruff.recommended` with no overrides behaves identically to running with no config file at all, and a preset-integrity test keeps the bundled presets from drifting out of sync with the rule registry (ADR-021).
 - **BREAKING: Retired the `complexity.npath` rule** - NPath produced false positives on sequential-but-simple branching and is redundant with the cognitive, cyclomatic, and nesting metrics. Remove any `complexity.npath` block from your config (it now fails closed as an unknown rule id) and regenerate baselines to drop stale npath findings. The registry now exposes 118 rules.
 - **BREAKING: Retired the synthetic `design.god-method` rubric** - Size and complexity findings remain visible and scored through their native pillars, but gruff no longer appends a second design finding when they overlap on the same symbol. Remove stale `design.god-method` entries from baselines; there is no config block to migrate because the old finding was not registry-backed. The registry count is unchanged because the old finding was never registry-backed.
+- **Correlated size/complexity findings share one penalty** - a method that is long *and* deeply nested *and* cyclomatically complex is one root cause, so scoring now bills it once instead of once per symptom. Findings sharing a `(file, symbol, line)` whose rule is in `{complexity.cognitive, complexity.cyclomatic, complexity.nesting-depth, size.method-length, size.parameter-count}` contribute a single shared weight (`max(member penalty) / member count`) to both their pillar and file scores; every finding still appears in the report and its pillar count. Composite and pillar grades rise for files that previously double- or triple-counted one over-large method; a file with no co-located cluster scores exactly as before. Findings, fingerprints, and the `gruff.analysis.v2` / `gruff.baseline.v1` schemas are unchanged, so baselines keep matching — only penalty weighting and the score `explanation` string change (ADR-024).
+- **`naming.boolean-prefix` gains an `acceptedBooleanNames` allowlist** - a boolean-returning method named `valid()` could previously only be cleared by the caller-breaking rename to `isValid()`; the new `rules.naming.boolean-prefix.options.acceptedBooleanNames` exact, case-insensitive allowlist accepts a caller-visible name as-is across methods, properties, and parameters, so a finding on a public name resolves with config rather than a breaking rename. Default empty; existing scans are unchanged.
 - **Complexity recalibration** - `complexity.halstead-volume` and `complexity.maintainability-index` are now `advisory` (informational, non-gating); `complexity.cognitive` tightened to a threshold of 20 and `complexity.nesting-depth` to 4; `complexity.cyclomatic` is now `warning`. The complexity pillar now gates on the metrics that track human comprehension rather than branch-counting proxies.
 - **Test-quality gate parity** - the "tested for real" mission leg now gates. `test-quality.no-assertions` (a test with no observable assertion), `test-quality.sut-not-called` (the named subject is never invoked), and `test-quality.tautological-type-assertion` (`assertInstanceOf(X, new X)`) are promoted to `error`, so `analyse --fail-on error` fails a suite whose tests prove nothing — and the cheapest way to satisfy each is a real assertion. The cosmetic-fix and style smells (`mock-without-expectation`, `trivial-assertion`, `eager-test`, naming/readability, …) stay at warning/advisory so the gate never forces ceremony. Each promotion fires only on genuinely fake tests, not on assertion helpers, data-provider matrices, `expectException`, or Pest `expect()` (ADR-022).
 - **Config accepts `advisory` severity** - the `rules.<id>.severity` config key now accepts `advisory` alongside `warning` and `error`, so rules that default to advisory can be pinned or overridden in `.gruff-php.yaml`.

Prefer JSON-string provider rows for heterogeneous inputs; when the class is near the 25-method cap, satisfy `multiple-aaa-cycles` by batching arrange-act-then-assert in one method instead of splitting into new public methods. At least two classes already sit *at* the cap: `tests/Config/ConfigLoaderTest.php` and `tests/Rule/Naming/NamingRulesTest.php` (search: `testGenericMethodNamesDetected`). A genuinely new public test method for a naming rule belongs in `tests/Rule/Naming/NamingRuleConfigurationTest.php` (the rule-option/config home — search: `testBooleanPrefixAllowedPrefixesCanBeConfigured`) or a split-out class like `IdentifierTokenizerTest`, not in `NamingRulesTest` — adding one there takes it to 26 and `analyse` fails the gate with `size.public-method-count` (observed 2026-05-31 when the `acceptedBooleanNames` test was first placed in `NamingRulesTest`).
+
+## Footgun: Two split-hex snapshot hashes lock the rule corpus and rule definitions; both break silently on fixture and defaultOptions changes
+
+**Status:** active | **Created:** 2026-05-31 | **Evidence:** OBSERVED
+
+Two regression tests pin a SHA-256 over a serialized snapshot, and each is sensitive to a change a different rule edit makes:
+
+- `tests/Rule/RuleRegressionSnapshotTest.php` (search: `testDefaultRuleRegistryFindingsStayStableAcrossFixtures`) hashes the canonical finding payload produced by scanning all of `tests/Fixtures`. Adding **any** file under `tests/Fixtures/**` — even a fixture authored for an unrelated rule's unit test — changes the `assertCount` of units, the `assertCount` of findings, *and* the hash, because the new file contributes its own incidental findings (`docs.missing-file-phpdoc`, `design.single-implementor-interface`, etc.).
+- `tests/Rule/RuleRegistryTest.php` (search: `testDefaultRuleDefinitionsStayStable`) hashes every rule's serialized definition, **including `defaultOptions`**. Adding an option key to any rule's `defaultOptions` changes this hash (the `assertCount(119, ...)` of definitions only moves when a rule is added or removed).
+
+Both expected hashes are written as a **two-part string concatenation** — e.g. `'18f7aaa06e6655716c0bd4' . 'b5c7048de8...'` — specifically so gruff's own `sensitive-data.high-entropy-string` self-scan does not flag the 64-hex literal during the dogfood `analyse`. If you replace a hash with a single 64-char literal, the dogfood scan flags it; preserve the split (the existing first segment is 22 chars in the regression test, 20 in the registry test).
+
+**Evidence:** 2026-05-31, the P6 fixture `tests/Fixtures/Complexity/bodyless.php` took the corpus from 150→151 units / 2504→2507 findings / new hash, and adding `acceptedBooleanNames` to `BooleanPrefixRule::definition()` `defaultOptions` (search: `acceptedBooleanNames`) changed the definition hash while the 119 count held.
+
+**Prevention:** There is no regenerate command for either literal. When you add a `tests/Fixtures/**` file or change any rule's `defaultOptions`/definition, expect both tests to fail and recompute deliberately: run the analysis the test runs (reuse the test's own `canonicalFindingPayload` / definition-serialization logic in a throwaway script, since the private helpers aren't callable) and read back the count + hash, then update the literal **preserving the two-segment split**. Confirm the new finding delta is exactly what you intended (e.g. only the new fixture's incidental findings) before trusting the new hash — a larger-than-expected delta means an existing finding's fingerprint moved.

 # Workflow Lessons
 
+## Lesson: Don't `git stash` to probe pre-existing state — it's not read-only and can entangle other stashes
+
+**Created:** 2026-05-31
+
+**What happened:** While verifying whether three `docs.stale-param-tag` warnings from the dogfood `analyse` were pre-existing or introduced this session, the agent ran `git stash push --keep-index --include-untracked -m "probe"` to "see the repo without my changes." That moved the session's uncommitted work into a new stash entry; the working tree reverted several edits (the relocated `acceptedBooleanNames` test, the `CHANGELOG.md` / decisions `README.md` additions, and the untracked `ADR-024` file). Recovery needed `git stash pop` plus re-applying one edit that did not survive the round-trip (a duplicate test then existed in two classes), while taking care not to disturb a pre-existing, unrelated `stash@{0}` ("WIP on dev: Add docblocks to test classes") that belonged to someone else. A risky, multi-step detour to recover information that was already available read-only.
+
+**Root cause:** Treating `git stash` as a "show me the tree without my changes" inspector. Stash mutates both the working tree and the index, so in a session with many uncommitted edits it is a destructive operation, and `--include-untracked` also sweeps up new files like a fresh ADR. It also collides with any pre-existing stash the user left. The actual question — "is this finding pre-existing or mine?" — is answerable without changing anything.
+
+**Prevention:** To decide whether a finding or file state is pre-existing versus introduced this session, stay read-only: (a) re-read the session-start `git status` snapshot already in the task context; (b) `git diff HEAD -- <file>` or `git log -1 -- <file>` to see whether the file was modified or committed before your edits; (c) check whether the finding's file is in your own changed-files list — here all three warnings were in `src/Rule/Docs/MissingParamTagRule.php` and `tests/Rule/Docs/DocsRulesTest.php`, neither of which the agent had touched, which settled it immediately. Never `git stash` to compare. If you genuinely must build against a clean tree, use a throwaway `git worktree add`, which leaves the working copy and any existing stashes untouched.
+
 ## Lesson: Universal defaults that ship via `init` must also flow through `AnalysisConfig` so existing projects benefit

+# gruff-code-quality.sh
+#
+# Purpose:
+#   Optional PostToolUse hook that runs the matching gruff analyzer after
+#   Edit / Write / MultiEdit and surfaces only findings tied to the lines
+#   just changed. This keeps the quality feedback on the agent's current
+#   work instead of forcing cleanup of unrelated debt elsewhere in the
+#   same file.
+#
+# Supported analyzers:
+#   - gruff-ts for .ts / .tsx / .js / .jsx
+#   - gruff-php for .php
+#   - gruff-go for .go
+#   - gruff-rs for .rs
+#   - gruff-py for .py
+#
+# Runtime contract:
+#   Payload is read from stdin as agent PostToolUse JSON. The hook prefers
+#   an edited file path from the payload, then falls back to git-changed
+#   supported files for runtimes that only expose the completed file tool
+#   event. It also needs a matching `.gruff-*.yaml` config at the repo root,
+#   a matching gruff binary, and `jq` for JSON filtering. Missing
+#   prerequisites fail soft: the edit is not blocked and whole-file gruff
+#   output is not printed as a fallback.
+#
+# Changed-line model:
+#   Prefer changed ranges from the PostToolUse payload when present.
+#   Otherwise parse `git diff --unified=0 -- <file>` for tracked files.
+#   New/untracked files are treated as fully changed. If no range can be
+#   derived, the hook exits quietly apart from a short stderr diagnostic.
+#
+# Output:
+#   Prints `[severity] path:line rule - message` for findings whose
+#   primary reported line intersects the changed ranges, then one compact
+#   suppressed-count line for same-file findings outside those ranges.
+#   The playbook footer is printed only when at least one changed-line
+#   finding is shown. If the analyzer reports the edited file as ignored by
+#   its `paths.ignore` config, the hook instead prints a single
+#   `skipped <path> - out of scope` line and surfaces no findings, so the
+#   agent does not try to fix a file the project deliberately excludes. Exit
+#   status stays 0 for analyzer findings and fail-soft diagnostics.

+# gruff-code-quality.sh
+#
+# Purpose:
+#   Optional PostToolUse hook that runs the matching gruff analyzer after
+#   Edit / Write / MultiEdit and surfaces only findings tied to the lines
+#   just changed. This keeps the quality feedback on the agent's current
+#   work instead of forcing cleanup of unrelated debt elsewhere in the
+#   same file.
+#
+# Supported analyzers:
+#   - gruff-ts for .ts / .tsx / .js / .jsx
+#   - gruff-php for .php
+#   - gruff-go for .go
+#   - gruff-rs for .rs
+#   - gruff-py for .py
+#
+# Runtime contract:
+#   Payload is read from stdin as agent PostToolUse JSON. The hook prefers
+#   an edited file path from the payload, then falls back to git-changed
+#   supported files for runtimes that only expose the completed file tool
+#   event. It also needs a matching `.gruff-*.yaml` config at the repo root,
+#   a matching gruff binary, and `jq` for JSON filtering. Missing
+#   prerequisites fail soft: the edit is not blocked and whole-file gruff
+#   output is not printed as a fallback.
+#
+# Changed-line model:
+#   Prefer changed ranges from the PostToolUse payload when present.
+#   Otherwise parse `git diff --unified=0 -- <file>` for tracked files.
+#   New/untracked files are treated as fully changed. If no range can be
+#   derived, the hook exits quietly apart from a short stderr diagnostic.
+#
+# Output:
+#   Prints `[severity] path:line rule - message` for findings whose
+#   primary reported line intersects the changed ranges, then one compact
+#   suppressed-count line for same-file findings outside those ranges.
+#   The playbook footer is printed only when at least one changed-line
+#   finding is shown. If the analyzer reports the edited file as ignored by
+#   its `paths.ignore` config, the hook instead prints a single
+#   `skipped <path> - out of scope` line and surfaces no findings, so the
+#   agent does not try to fix a file the project deliberately excludes. Exit
+#   status stays 0 for analyzer findings and fail-soft diagnostics.

 ## Update (2026-05-31): return-comment restored
 
+**Superseded for return-comment by ADR-025 (2026-06-01):** the paragraph below is
+retained as historical context only. `docs.return-comment` now means "value-returning
+functions need a described `@return` tag," not "comment above every `return`."
+
 `docs.return-comment` is reinstated as the original blanket rule: a one-line comment directly above every `return`. The earlier deletion treated it as low-signal ceremony, but that mis-read the rule's purpose. gruff governs AI-generated code so a human who didn't write it can verify it; a comment stating *why* each exit returns is a verification surface a reviewer diffs against the code — the same principle that makes doc comments mandatory. The rule stays advisory, and like other debt-heavy rules its existing-code findings are meant to be frozen via the baseline so it gates new and changed returns rather than forcing a backfill of gruff's own tree. `docs.continue-comment` remains deleted; only the return variant is restored, so the rest of this ADR's reasoning still applies to the continue rule.

+# ADR-025: Rework `docs.return-comment` to a described-`@return` rule
+
+**Status:** Accepted
+**Date:** 2026-06-01
+**Author(s):** Matthew Hansen
+**Supersedes scope of:** the 2026-05-31 "return-comment restored" update to ADR-006,
+which reinstated the blanket "one-line comment directly above every `return`" shape.
+ADR-006's deletion of `docs.continue-comment` still stands.
+
+## Context
+
+The 2026-05-31 update to ADR-006 restored `docs.return-comment` as the original blanket
+rule: a standalone `//` comment directly above every `return` statement
+(`DirectLineComment::hasCommentAbove`). The intent was sound — a return's contract is a
+verification surface a reviewer diffs against the code — but the shape contradicts the
+project's own comment bar. `code-comments.md` rations inline comments to a non-obvious
+WHY and names "restating the code" as an antipattern; a mandatory `//` above every return
+is exactly the narration it omits by default. The rule therefore taught adopters to write
+the comments the comment bar tells them to delete, and its findings landed inside function
+bodies rather than on the contract surface PHPDoc consumers and IDEs already read.
+
+Three documentation rules touch return tags, and the gap between them is the real target:
+
+- `docs.missing-return-tag` (`MissingReturnTagRule`) owns **presence** — a documented
+  function-like with no `@return` at all (exempts `__construct` / `__destruct`).
+- `docs.bare-phpdoc-tags` (`BarePhpdocTagsRule`) owns **the tags-only docblock** — fires
+  only when the whole docblock is tags with no prose summary.
+- A value-returning function with a summary line **plus** a bare `@return Type` trips
+  neither: presence is satisfied and the docblock is not tags-only. That gap is where the
+  contract silently goes undescribed.
+
+## Decision
+
+Rework `docs.return-comment` (keeping the id) so it fires when a **value-returning**
+function-like declaration has an `@return` tag that is **present but undescribed**.
+
+Locked semantics:
+
+- **Value-returning** = the declared return type is present and is not `void` or `never`;
+  when the declared type is absent, fall back to "has at least one `return <expr>;`".
+- **Exempt** `__construct` / `__destruct` exactly as `MissingReturnTagRule` does, plus any
+  `void`/`never` return — there is no result to describe.
+- **Fire only** when a docblock exists, carries an `@return`, and that `@return` has no
+  description. Missing docblock and missing `@return` stay owned by
+  `docs.missing-public-phpdoc` / `docs.missing-return-tag`; a wholly-bare docblock stays
+  owned by `docs.bare-phpdoc-tags`. No double-reporting.
+- **The rule checks for a description, not punctuation.** It reuses
+  `BarePhpdocTagsRule`'s depth-aware `hasReturnTagDescription()` (tolerant of spaces inside
+  `array<string, int>` generics), extracted into a shared `PhpdocTagText` helper both rules
+  call. "Has any prose after the type" is the bar; the `-` separator is a house convention
+  applied during conversion, not a rule-enforced character.
+- The id stays `docs.return-comment`; severity stays `advisory`; confidence stays `high`;
+  the registry slot and rule **count** are unchanged (this is a rework, not an add/remove).
+  Only `name`, `description`, and behaviour change.
+
+`DirectLineComment` (used only by this rule) is removed. No rule writes or requires a `//`
+above a return after this change.
+
+## Division of labour (must stay disjoint)
+
+| Rule | Owns | Fires when |
+| --- | --- | --- |
+| `docs.missing-return-tag` | presence of `@return` | documented function-like, no `@return` at all (ctor/dtor exempt) |
+| `docs.bare-phpdoc-tags` | the tags-only docblock | whole docblock is tags, no prose summary |
+| `docs.return-comment` (reworked) | description of an existing `@return` | value-returning, `@return` present, no description |
+
+## Failure Mode Comparison
+
+| Option | What fails | Why rejected or accepted |
+| --- | --- | --- |
+| Keep the blanket "`//` above every return" rule | Teaches the inline narration `code-comments.md` rations against; findings sit in bodies, not on the contract; gruff cannot satisfy it without ceremony. | Rejected. Wrong surface, contradicts the comment bar. |
+| Rename the id to `docs.return-description` | Cleaner name, but breaks every config key, baseline entry, `docs/rules.md` row, and registry slot for adopters. | Rejected for now; deferred as a separate breaking decision. |
+| Enforce the literal `-` separator in the rule | Brittle; punctuation is a house convention, and a description with a different separator is still a description. | Rejected. Rule checks for a description; the hyphen is convention-only. |
+| Rework to "described `@return` for value-returning functions" | Adopters' bare-`@return` findings shift, and the conversion backfills descriptions instead of freezing them in a baseline. | Accepted. Puts the contract on the surface reviewers diff, fills the real gap between the sibling rules, and reuses tested detection. |
+
+## Consequences
+
+- `ReturnCommentRule` iterates `ClassMethod`/`Function_` nodes (like the sibling docs
+  rules) instead of `Return_` nodes; `DirectLineComment` and its references are deleted.
+- `RuleRegistryTest::testDefaultRuleDefinitionsStayStable` and
+  `RuleRegressionSnapshotTest` digests/counts shift with the new `name`/`description` and
+  the new finding set; recompute, do not hand-edit. The rule **count** stays 128.
+- The codebase is converted repo-wide to the house format
+  (`@param <Type> $name - <desc>`, `@return <Type> - <desc>`, blank ` *` line before
+  `@return`); any `//`-above-return comments are removed. Comments/docblocks only — no
+  executable code changes.
+- Adopter baselines may shift as the `docs.return-comment` finding set changes; the id is
+  unchanged so existing config keys keep working.
+
+## Reversibility
+
+Two-way door before 1.0. Reverting to the blanket shape requires a new ADR with fresh
+evidence, because it reintroduces the inline-narration pressure this decision removes.
+Renaming the id remains available as a separate, deliberately-decided breaking change.

+## Footgun: PHPStan/Psalm array-shape exemptions need a "concrete sibling" gate, not "any nested mixed"
+
+**Status:** active | **Created:** 2026-05-27 | **Evidence:** OBSERVED
+
+`src/Rule/Modernisation/PhpDocMixedOveruseRule.php` (search: `isPreciseArrayShape`) exempts `array{...}` shapes that name at least one sibling field with a non-mixed type, on the basis that the nested `mixed` describes a heterogeneous leaf inside a typed envelope. The naive form of this rule — "any nested mixed inside any parametric type is fine" — silently exempts `array<string|int, mixed>` (mixed-keyed bag), `Collection<mixed>` (single-leaf generic), and `array{value: mixed}` (single-mixed-field shape), all of which are genuine type sloppiness the rule should keep flagging. The discriminator is "is there at least one CONCRETE sibling field?"; without it the exemption swallows real signal.
+
+**Evidence:** Healthkit reviewer report section 7 (`.goat-flow/scratchpad/gruff-php-improvement-feedback.md`). The reviewer's original phrasing was "nested mixed inside any parametric type should be fine"; applied literally that exempts `Collection<mixed>` which is clearly not a precise envelope. The implemented rule reads the array-shape body, splits on top-level commas (depth-aware via `splitTopLevelComma`), finds the first top-level colon per pair (depth-aware via `topLevelColonIndex`), and returns true only when at least one pair's value type is NOT exactly `mixed` (case-insensitive). Fixtures at `tests/Fixtures/Modernisation/phpdoc-mixed-overuse.php` `preciseArrayShape*` cover both directions.
+
+**Prevention:** When extending a type-shape exemption beyond a single canonical form, write the counter-fixture first. Every "loose" shape (mixed-keyed bag, single-mixed-field shape, mixed-only generic) gets a `*StillFires` fixture method that asserts the exemption did NOT swallow it. Only after the counter-fixtures are in place add the positive `*IsAllowed` cases. The shape-detector must use a depth-aware splitter (commas inside `<>{}()[]` belong to the inner shape, not the outer one); a naive `explode(',', ...)` would split `array{entries: list<array<string, mixed>>, total: int}` mid-list and corrupt the parse.
+
+## Footgun: PHPStan rejects prose attached to multiline array-shape tags
+
+**Status:** active | **Created:** 2026-06-01 | **Evidence:** OBSERVED
+
+`docs.return-comment` only needs to know whether an `@return` tag has prose after the type, and
+`src/Rule/Docs/PhpdocTagText.php` (search: `returnTagBody`) now reads multiline array-shape tags
+through their closing line. That made comments such as `@return array{ ... } - description` clear
+the gruff rule, but PHPStan treats the whole structural tag body as type syntax; prose after the
+closing `}` produced `phpDoc.parseError` in `src/Command/ListRulesCommand.php` (search:
+`ruleDetailPayload`) and `src/Source/SourceDiscovery.php` (search: `buildGitDiscoveryRequest`),
+which then cascaded into `missingType.iterableValue` and `argument.type` errors.
+
+**Prevention:** For multiline precise array shapes, keep the human-facing `@return` tag broad and
+described (`@return array - ...` or `@return array|null - ...`), then put the precise shape in a
+separate `@phpstan-return array{...}` tag with one complete `key: type` pair per line. Do not put a
+description after the closing `}` of an `@return` or `@phpstan-return` array shape; PHPStan reads it
+as malformed type syntax, not prose. When composing long PHPStan type aliases, avoid splitting the
+alias name from its type body across physical lines; `tests/Mutation/InfectionReportParserTest.php`
+(search: `InvalidReportNestedA`) uses smaller intermediate aliases instead.

 **Resolution:** `lateAssignments` now walks `Expr\ArrayDimFetch` chains down to the underlying expression via `recordPropertyMutation()` before consulting the helper, AND iterates `Stmt\Unset_` nodes separately so `unset($this->prop['k'])` is treated as the same kind of post-constructor mutation. The shared helper (`ModernisationNodeHelper::propertyFetchName`/`isThisPropertyFetch`) stays untouched because only one rule needs the walk today; expanding the helper to do it would change the behaviour of every consumer for no current benefit.
 
 **Prevention:** When a modernisation rule reasons about "this property mutates after the constructor", it must check every AST shape that PHP allows to mutate the container without textually mentioning the property: plain `Expr\Assign` whose LHS is a `PropertyFetch`, `Expr\Assign` whose LHS is one-or-more `ArrayDimFetch` wrapping a `PropertyFetch`, and `Stmt\Unset_` whose arg list contains the same shape. `Expr\AssignOp::*` (compound assigns like `$this->count += 1`) is `Expr\AssignOp::class`, not `Expr\Assign::class`, and the same nodeFinder query would miss it — when a future rule needs compound-assign awareness, extend `recordPropertyMutation()` to be called from the `AssignOp` walker as well.

+- **`docs.return-comment` now describes `@return` tags** - the rule id is unchanged, but its contract is redefined from "one-line comment directly above every `return`" to "value-returning functions with an existing `@return` tag need prose after the type." Missing tags stay owned by `docs.missing-return-tag`, wholly tag-only docblocks stay owned by `docs.bare-phpdoc-tags`, and void/never returns plus constructors/destructors are exempt. Existing baselines may shift because the finding surface moved from return statements to the PHPDoc contract.
 - **`docs.missing-param-tag` now covers non-public methods** - the rule previously inspected only public methods; it now flags any documented method or function (private and protected included) whose docblock omits an `@param` for a parameter, matching the project's mandatory-doc-on-every-unit stance. Freeze existing private-method gaps via the baseline so the rule gates new code rather than forcing a backfill.

+claude[bot], or any other repo bot) before Pass 1, and how to report
+the human-vs-automated finding split in Review Integrity.

+Borrowed from awslabs/cli-agent-orchestrator PR #245 review pattern, where
+the human reviewer posted a Copilot/Manual finding tally that made the
+review accountable ("Copilot 11, Manual 3, accuracy 100%").
+
+## Ingestion
+
+The Step 0 `gh pr view` already includes `reviews,comments` in its `--json`
+field list. Parse the returned payload:

+- `reviews[]` - structured review submissions; check `author.login` for
+  the bot inventory below.
+- `comments[]` - issue-comment-style entries on the PR; same author check.

+Treat findings authored by any of these as the **automated-review index**:

+- `copilot-pull-request-reviewer`
+- `github-advanced-security`
+- `claude[bot]` (Anthropic GitHub App)
+- any other repo-specific bot the user names
+
+For each automated finding, record `{ reviewer, file, line?, brief }`
+where `brief` is the first 80 chars of the finding body. The index is the
+authoritative known-findings set for the rest of the review.

+If no automated reviewers commented, record `no-automated-review-present`
+in Review Integrity and skip overlap tagging.

+- `[overlap:<reviewer>]` - this human finding matches a known finding in
+  the automated-review index (same file, semantically similar brief).
+  Example: `[overlap:copilot-pull-request-reviewer]`.
+- `[new]` - this human finding does not appear in the index. Net-new
+  signal from this review.
+
+Semantic match heuristics: same `file` + Jaccard token overlap > 0.4 on
+the brief, OR same `file + line` exact. False matches favor `[new]` -
+better to over-attribute as net-new than to silently absorb an
+automated-only finding.
+
+## Review Integrity Surface Extension
+
+Extend the Review Integrity surface defined in SKILL.md with this line
+when in PR mode:
+
+```
+- Automated-reviewer overlap: <K> overlap with <reviewer-list>, <M> net-new
+```
+
+When no automated review: `Automated-reviewer overlap: no-automated-review-present`.
+When fetch failed: include `automated-review-uningested` in Degradation flags.
+Outside PR mode: omit the line entirely or write `n/a`.
+
+## Degradation Flag
+
+`automated-review-uningested` joins the existing flags list. Trigger when
+`gh pr view` returned `reviews,comments` but parsing did not produce a
+usable bot finding index. Distinct from `no-automated-review-present`
+which is the legitimate "no bot has commented yet" state.
+
+## Why This Surface Exists
+
+When automated review and human/skill review run in sequence, the human
+reviewer's value is the *delta*: findings the automated tools missed. A
+review that silently re-flags the same Copilot findings duplicates work
+and inflates the apparent review yield without adding signal.
+
+The overlap surface makes the delta explicit. It also rewards the
+automated reviewer for accurate findings (`[overlap]` is a positive
+signal, not a demotion) and surfaces gaps in automated coverage that the
+human review filled (`[new]` count is the per-PR review value).
+
+## Anti-Patterns
+
+- **Silently omit overlap reporting when automated review exists.**
+  Defeats the surface; presents human review as if it were standalone.
+- **Mark every finding `[new]` to inflate yield.** The semantic-match
+  heuristic should err toward `[new]`, but obvious overlap (same
+  file+line, same word-for-word brief) is `[overlap]`.
+- **Refuse to run a finding because Copilot already flagged it.**
+  `[overlap]` is a tagging signal, not a suppression signal. Surface
+  the finding with the tag; the reviewer's confirmation independently
+  validates the automated finding.
+- **Treat `automated-review-uningested` as `no-automated-review-present`.**
+  They are different states with different implications.

-# deny-dangerous.sh - PreToolUse hook: blocks dangerous commands before execution
-# goat-flow-hook-version: 1.5.3
-# =============================================================================
-# Event:  PreToolUse / equivalent pre-command hook for the current runtime
-# Match:  Bash tool calls
-# Exit 0: allow the command
-# Exit 2: block the command (stderr message shown to the agent as the reason)
-#
-# Install: place in the runtime's hooks directory and register it with the
-# runtime's pre-tool / pre-command hook config.
+# shellcheck disable=SC2034,SC2317,SC2319
+
+# deny-dangerous.sh
 #
-# Limitations:
-# - Best-effort pattern matching on literal shell commands
-# - Does NOT catch: variable indirection ($cmd), shell aliases, or encoded
-#   commands (base64-decoded payloads, $'...' C-style escapes, etc.)
-# - Deeply nested command substitution beyond 3 levels is blocked as a
-#   precaution rather than parsed
-# - Defense in depth: combine with runtime deny patterns + instruction-file rules
-# NOTE: direct literal `source .env` and similar shell-level secret reads ARE blocked. Plain
-#   `.env.example` reads are allowed; writes still block. See self-test cases.
-# =============================================================================
+# Single goat-flow PreToolUse guardrail dispatcher. It contains the shared
+# payload parser/normalizer and sources policy modules from the committed
+# .goat-flow/hook-lib/ store, then runs destructive-shell, secret-path, and
+# repository-write checks in one process.

+# Automated-Review Overlap Protocol
+
+Loaded by `/goat-review` in PR mode. Defines how to ingest existing
+automated-reviewer findings (Copilot, CodeQL/github-advanced-security,
+claude[bot], or any other repo bot) before Pass 1, and how to report
+the human-vs-automated finding split in Review Integrity.
+
+Borrowed from awslabs/cli-agent-orchestrator PR #245 review pattern, where
+the human reviewer posted a Copilot/Manual finding tally that made the
+review accountable ("Copilot 11, Manual 3, accuracy 100%").
+
+## Ingestion
+
+The Step 0 `gh pr view` already includes `reviews,comments` in its `--json`
+field list. Parse the returned payload:
+
+- `reviews[]` - structured review submissions; check `author.login` for
+  the bot inventory below.
+- `comments[]` - issue-comment-style entries on the PR; same author check.
+
+Treat findings authored by any of these as the **automated-review index**:
+
+- `copilot-pull-request-reviewer`
+- `github-advanced-security`
+- `claude[bot]` (Anthropic GitHub App)
+- any other repo-specific bot the user names
+
+For each automated finding, record `{ reviewer, file, line?, brief }`
+where `brief` is the first 80 chars of the finding body. The index is the
+authoritative known-findings set for the rest of the review.
+
+If no automated reviewers commented, record `no-automated-review-present`
+in Review Integrity and skip overlap tagging.
+
+If `gh pr view` fetched the payload but parsing failed (rate-limited,
+schema change, or no parsable bot entries), flag
+`automated-review-uningested` in Review Integrity.
+
+## Pass 2 Overlap Tagging
+
+After Pass 2 produces its findings list, tag each finding:
+
+- `[overlap:<reviewer>]` - this human finding matches a known finding in
+  the automated-review index (same file, semantically similar brief).
+  Example: `[overlap:copilot-pull-request-reviewer]`.
+- `[new]` - this human finding does not appear in the index. Net-new
+  signal from this review.
+
+Semantic match heuristics: same `file` + Jaccard token overlap > 0.4 on
+the brief, OR same `file + line` exact. False matches favor `[new]` -
+better to over-attribute as net-new than to silently absorb an
+automated-only finding.
+
+## Review Integrity Surface Extension
+
+Extend the Review Integrity surface defined in SKILL.md with this line
+when in PR mode:
+
+```
+- Automated-reviewer overlap: <K> overlap with <reviewer-list>, <M> net-new
+```
+
+When no automated review: `Automated-reviewer overlap: no-automated-review-present`.
+When fetch failed: include `automated-review-uningested` in Degradation flags.
+Outside PR mode: omit the line entirely or write `n/a`.
+
+## Degradation Flag
+
+`automated-review-uningested` joins the existing flags list. Trigger when
+`gh pr view` returned `reviews,comments` but parsing did not produce a
+usable bot finding index. Distinct from `no-automated-review-present`
+which is the legitimate "no bot has commented yet" state.
+
+## Why This Surface Exists
+
+When automated review and human/skill review run in sequence, the human
+reviewer's value is the *delta*: findings the automated tools missed. A
+review that silently re-flags the same Copilot findings duplicates work
+and inflates the apparent review yield without adding signal.
+
+The overlap surface makes the delta explicit. It also rewards the
+automated reviewer for accurate findings (`[overlap]` is a positive
+signal, not a demotion) and surfaces gaps in automated coverage that the
+human review filled (`[new]` count is the per-PR review value).
+
+## Anti-Patterns
+
+- **Silently omit overlap reporting when automated review exists.**
+  Defeats the surface; presents human review as if it were standalone.
+- **Mark every finding `[new]` to inflate yield.** The semantic-match
+  heuristic should err toward `[new]`, but obvious overlap (same
+  file+line, same word-for-word brief) is `[overlap]`.
+- **Refuse to run a finding because Copilot already flagged it.**
+  `[overlap]` is a tagging signal, not a suppression signal. Surface
+  the finding with the tag; the reviewer's confirmation independently
+  validates the automated finding.
+- **Treat `automated-review-uningested` as `no-automated-review-present`.**
+  They are different states with different implications.

-# goat-flow-hook-version: 1.5.3
-# =============================================================================
-# Event:  PreToolUse / equivalent pre-command hook for the current runtime
-# Match:  Bash tool calls
-# Exit 0: allow the command
-# Exit 2: block the command (stderr message shown to the agent as the reason)

+# deny-dangerous.sh
 #
-# Limitations:
-# - Best-effort pattern matching on literal shell commands
-# - Does NOT catch: variable indirection ($cmd), shell aliases, or encoded
-#   commands (base64-decoded payloads, $'...' C-style escapes, etc.)
-# - Deeply nested command substitution beyond 3 levels is blocked as a
-#   precaution rather than parsed
-# - Defense in depth: combine with runtime deny patterns + instruction-file rules
-# NOTE: direct literal `source .env` and similar shell-level secret reads ARE blocked. Plain
-#   `.env.example` reads are allowed; writes still block. See self-test cases.
-# =============================================================================

-#     would silently fail to populate and the for-loop iterates zero times,
-#     meaning a chained `&& git push` would no longer be split out.
-#   - Avoids the process-substitution subshell that `mapfile < <(...)` would
-#     spawn (slow on Windows gitbash where each subshell is ~30ms).

+# deny-dangerous-self-test.sh
+#
+# Purpose:
+#   Central self-test runner for the goat-flow deny-dangerous hook
+#   (shell, writes,
+#   paths). Drives each hook with curated commands that
+#   MUST block and MUST allow, exercises the Copilot and Antigravity
+#   JSON payload shapes end-to-end, and verifies the fail-closed
+#   behaviour when .goat-flow/hook-lib is missing from a hook's directory.
+#
+#   Each deny hook re-execs into this script when invoked with
+#   `--self-test[=mode]`, so `deny-dangerous.sh --self-test` is equivalent to
+#   `deny-dangerous-self-test.sh --self-test --hook shell`.
+#
+# Usage:
+#   bash deny-dangerous-self-test.sh [--self-test[=smoke|full]] [--hook <name>]
+#
+#   Examples:
+#     bash deny-dangerous-self-test.sh                          # smoke
+#     bash deny-dangerous-self-test.sh --self-test=full         # full
+#     GOAT_DENY_DANGEROUS_HOOK=.claude/hooks/deny-dangerous.sh bash deny-dangerous-self-test.sh
+#
+# Modes:
+#   smoke   Fast coverage of the canonical block/allow cases per hook,
+#           plus the missing-hook-lib fail-closed checks. Default.
+#   full    Smoke plus comprehensive per-hook block/allow coverage and
+#           Copilot/Antigravity JSON payload checks.
+#
+# Exit:
+#   0 when every executed assertion passes; prints a PASS summary line.
+#   1 when any assertion fails or an unsupported mode is requested.
+#   Each failure is printed as `FAIL: <label>` to stderr, followed by a
+#   FAIL summary line.

+If `connect` cannot find a running Chrome with remote debugging, do not silently fall back. Surface the choice to the user with both options and let them pick - installed-Chrome and managed-Chromium are not equivalent because each touches different state:
 
 1. **Use the user's real Chrome.** They must enable remote debugging first: open `chrome://inspect/#remote-debugging` or relaunch Chrome with `--remote-debugging-port=9222`. Then retry `browser-use connect`.
 2. **Use managed Chromium with a Chrome profile.** Run `browser-use profile list` to show available profiles, ask which one, then run `browser-use --profile "ProfileName" open <url>`. This launches a separate Chromium instance with the chosen profile (cookies, logins, extensions); no Chrome relaunch needed.
 
-Both paths require explicit user approval — they read login state. Never pick one autonomously.

+# Changelog
+
+Use this when writing or editing `CHANGELOG.md` - the durable, in-repo, append-only record of what shipped in each version. This playbook covers WHAT to write, HOW to source it from the diff, how to align with SemVer, and the cadence options for keeping the file current.
+
+For the per-release narrative aimed at end users (GitHub release body, blog post, email, in-app "what's new"), see the sibling [`release-notes.md`](./release-notes.md). The changelog is the source of truth; release notes are a derived view.
+
+## Availability Check
+
+This is a discipline reference, not a runnable tool. Load it when:
+
+- Drafting a new version section in `CHANGELOG.md`.
+- Reviewing a `CHANGELOG.md` diff before merge.
+- Auditing an existing changelog to spot drift, missing entries, or misclassified version bumps.
+- Bumping the version in `package.json` (or equivalent) and updating the changelog to match.
+
+No availability command applies (the discipline ships with the playbook, not a tool). Some projects have a validation harness that catches a subset of changelog defects automatically - snapshot-claim linters, version-surface parity scripts, link checkers, or a release preflight. When those exist, name them here and run them; they catch mechanical errors but not the substantive ones this playbook protects against, so they augment the **Verification Gate** below, they do not replace it.
+
+## Intent
+
+A contributor or downstream maintainer opens `CHANGELOG.md` to answer one of three questions:
+
+1. **What changed between version A and version B?** They are diffing two known versions and want a complete list.
+2. **What is the contract now?** They are integrating against the current version and need to know what stabilised, what moved, and what is gone.
+3. **Did this thing I noticed actually ship?** They saw new behaviour or a bug fix and want confirmation plus a version anchor.
+
+If your changelog entry does not answer all three for someone who has never read your commit history, it is not yet a changelog entry - it is a working memo.
+
+The customer is a future reader who has none of your context. They cannot read your Slack, your closed issues, your PR descriptions, or your commit log in full. They have the changelog, the code, and possibly the diff. Write so they need only the first.
+
+## Convention
+
+Pick one convention per project and stick to it. Two are common; **the project's existing `CHANGELOG.md` always wins** - if it follows neither, mirror what it has.
+
+### Default for new projects: Keep a Changelog
+
+[Keep a Changelog](https://keepachangelog.com): one `CHANGELOG.md` at the repo root, top-newest, an optional `## [Unreleased]` section above the latest tag, and every change sorted into a small fixed set of categories (Added / Changed / Deprecated / Removed / Fixed / Security). Skeleton:
+
+```markdown
+# Changelog
+
+## [Unreleased]
+
+### Added
+- New `--timeout` flag for setting request timeouts in seconds.
+
+## [1.4.0] - 2026-03-12
+
+### Added
+- ...
+### Changed
+- ...
+### Deprecated
+- ...
+### Removed
+- ...
+### Fixed
+- ...
+### Security
+- ...
+```
+
+### Alternative: themed-narrative
+
+Many established projects (this repo's own `CHANGELOG.md` included) use a freeform shape: a `## vX.Y.Z - YYYY-MM-DD` header, a one-paragraph intro that names the release theme, and themed bullets without per-category sub-headings. Skeleton:
+
+```markdown
+# Changelog
+
+## v1.4.0 - 2026-03-12
+
+Cold-start performance pass plus a new authenticated upload endpoint. No breaking changes; existing callers are unaffected.
+
+- **Faster cold start** - first request now serves in 0.6s vs 4.3s previously (`bench/cold-start.bench.ts`).
+- **Authenticated uploads** - new `POST /v1/uploads` endpoint accepts multipart payloads up to 25MB with bearer-token auth.
+- **Fixed: cache invalidation on schema migration** - prior versions could serve stale rows for up to 60s after a migration; cache now flushes synchronously.
+```
+
+The themed-narrative shape sacrifices machine-parseability (no tools that auto-summarise Keep-a-Changelog categories) for human-readability (one scan reveals what the release is *about*, not just what it lists). Pick this style when the audience reads changelogs end-to-end rather than diffing them.
+
+**The rules below apply to both conventions** - SemVer alignment, source-from-the-diff, BREAKING-change discipline, voice, antipatterns, and the verification gate are independent of category mechanics. Only the **Categories** section and the **Stale Unreleased** antipattern below are Keep-a-Changelog-specific; they are no-ops for themed-narrative projects.
+
+## Categories (Keep a Changelog only)
+
+If the project follows Keep a Changelog, every entry sorts into one of these. (Themed-narrative projects skip this section.)
+
+| Category | Use for |
+|---|---|
+| **Added** | New features, endpoints, flags, options, files - behaviour that did not exist |
+| **Changed** | Behaviour that was already present and now works differently (non-breaking) |
+| **Deprecated** | Behaviour that still works but will be removed; pair with a target removal version |
+| **Removed** | Behaviour that existed in the prior release and no longer ships |
+| **Fixed** | Bugs - behaviour that was wrong by design or contract |
+| **Security** | Vulnerabilities; always include severity and whether disclosure preceded the release |
+
+A single change rarely fits two categories. Pick the one that matches the user's mental model:
+
+- A new flag that fixes a bug → **Added** (the flag is what the user touches).
+- A bug fix that required removing a flag → **Removed** for the flag, **Fixed** for the bug, with cross-references.
+- A breaking rename → **Changed** with a `BREAKING:` marker; do not split into Added + Removed.
+
+## SemVer Alignment
+
+If the project uses [SemVer](https://semver.org):
+
+- **MAJOR** - any breaking change to a documented contract. Removing a flag, changing the meaning of an existing flag, dropping a supported runtime, changing default behaviour in a way that breaks reasonable callers.
+- **MINOR** - new behaviour that does not break existing callers. New endpoints, new flags with safe defaults, optional fields, new error codes paired with broader handling.
+- **PATCH** - bug fixes, doc-only changes, internal refactors, perf wins that do not change observable behaviour.
+
+A MAJOR bump that contains only fixes (no breaks) is a misclassification - users will skip it expecting churn. A PATCH that contains a breaking change is a worse misclassification - users will apply it expecting safety.
+
+Mismatch between the bump and the changelog content is a signal of one of two errors: either the bump is wrong, or the changelog is hiding the real change. Resolve before publishing.
+
+For projects using **calendar versioning** (`2026.05.0`), SemVer guarantees do not apply by convention - say so in the README and flag breaking changes by prose, not by version-number signal.
+
+For projects on **0.x.y** (pre-1.0): SemVer's stability guarantees do not apply by convention either - a minor bump (`0.4 → 0.5`) is permitted to break. State this in the README so users do not assume the post-1.0 SemVer contract. The `BREAKING:` marker is still required, and a migration path is still required - the only thing 0.x relaxes is the version-number signal.
+
+## Source: the Diff, Not the Commits
+
+The most common failure mode is summarising commit subjects instead of reading what actually changed. Commit subjects are written when the work is incomplete and reflect the author's intent at the time, not the merged behaviour.
+
+Read in this order:
+
+1. **`git diff <prev-tag>..<current-tag> --stat`** to see scope.
+2. **`git diff <prev-tag>..<current-tag> --name-status`** to spot adds / deletes / renames.
+3. **The actual file content of the most-changed areas.** Read the new code; do not infer from commit messages.
+4. **`git log --oneline <prev-tag>..<current-tag>`** last, as one signal among several - never as the spine of the entry.
+
+A merged feature often spans several commits, none of whose subjects describe the final shipped behaviour. A reverted change leaves commits in the log that did not ship. A rename can produce 1000 lines of "diff" with zero behaviour change. Only the diff tells you what shipped.
+
+If the project uses squash merges, the commit subject is closer to user-impact-shaped but still incomplete - the PR body often carries the real description, and even that was written before the squashed work was merged.
+
+## Breaking Changes
+
+Breaking changes get a `BREAKING:` prefix on the entry (or a top-of-entry callout block) and a migration path. Without a migration path, the entry is documenting an incident, not a release.
+
+Required elements:
+
+1. **`BREAKING:` marker** at the start of the bullet or a callout block above it.
+2. **What broke** - the contract that changed, named precisely (function signature, env var, flag, response shape, default value).
+3. **Why it broke** - one sentence. Compliance, security, removing dead complexity, fixing a misdesign. Readers tolerate breakage better when they know the reason.
+4. **Migration path** - exact steps. Before / after code snippets when possible. A script or codemod when available.
+5. **Deprecation precursor** - if the breaking change had a prior deprecation entry, link to it. Breaking changes that ship without prior deprecation should explain why (the deprecation cycle was not viable; the bug was security-critical; this is a 0.x release where minor bumps can break).
+
+Example (outer fence is four backticks so the inner ` ```bash ` block renders correctly inside the rendered changelog entry):
+
+````markdown
+- **BREAKING: `--legacy-format` flag removed.** Replace with `--format=v1` for the same behaviour. Deprecated in 1.4.0 (see entry below); removal was scheduled for 1.6.0.
+
+  Migration:
+  ```bash
+  # before
+  mytool export --legacy-format
+  # after
+  mytool export --format=v1
+  ```
+````
+
+Anti-example:
+
+```markdown
+- BREAKING: removed `--legacy-format`. Update your scripts.
+```
+
+The bad one tells a user something is broken but not what to do. The good one names the replacement, references the deprecation, and shows the exact substitution.
+
+For deprecation entries (one or more releases before removal), name the target removal version:
+
+```markdown
+### Deprecated
+- `--legacy-format` flag is deprecated; will be removed in 1.6.0. Use `--format=v1` for the same behaviour.
+```
+
+A deprecation entry without a target version becomes a future surprise.
+
+## Cadence
+
+Three viable cadences. Pick one per project and stick to it.
+
+**Write-at-commit (Keep a Changelog default).** Every PR that ships user-visible behaviour appends to an `## [Unreleased]` section at the top. On release day, rename `Unreleased` to the version + date and start a new empty `Unreleased` above it.
+
+- Pro: change descriptions written by the person closest to the change, while context is fresh.
+- Pro: release day is mechanical and low-risk.
+- Con: merge conflicts on the changelog file.
+
+**Write-at-release.** Diff the prior tag against `main`, theme the changes, write the entry in one sitting before tagging.
+
+- Pro: themes are clearer when you can see the whole release.
+- Pro: no merge conflicts mid-cycle.
+- Con: requires the writer to reconstruct context from diffs, with the risk of missing intent that lived only in the PR.
+- Con: release day takes longer.
+
+**Tool-assisted (changesets, towncrier, news-fragments, release-please, etc.).** Contributors drop a small per-PR fragment (`.changeset/*.md`, `newsfragments/*.bugfix`, conventional-commit subjects); a tool concatenates and themes them at release time, then writes the `CHANGELOG.md` entry and (often) bumps the version.
+
+- Pro: no merge conflicts; each PR writes its own file.
+- Pro: changelog generation is reproducible and reviewable as a diff.
+- Con: tool output is only as good as its inputs - a vague `fix(api): tweak` produces a vague entry. The "source from the diff" rule still applies: before merging the auto-generated entry, walk the actual diff and rewrite any entries that misrepresent what shipped.
+- Con: tool conventions become a new contract contributors must learn; misuse silently produces wrong-category or wrong-severity entries.
+
+A hybrid works: contributors add a bullet to `Unreleased` at PR time (or drop a tool fragment), the release manager re-themes and rewrites at release time using both the staged content AND the diff as input. The staged content becomes one input among several, not the final entry.
+
+Whichever cadence: **never write entries from memory alone, and never accept tool output without reading the diff**. The diff is the source of truth.
+
+## Voice and Specificity
+
+Use **active voice**, **past tense or imperative**, **specific names**, and **no marketing language**.
+
+Active voice:
+- Bad: "An option has been added that allows configuration of timeouts."
+- Good: "Added `--timeout` for setting request timeouts in seconds."
+
+Specific names:
+- Bad: "Improved the dashboard."
+- Good: "Plans view (`src/dashboard/views/plans.html`) now reads `.goat-flow/tasks/` and previews milestones."
+
+No marketing:
+- Bad: "Blazing-fast new query engine, ground-up rewrite for the AI era."
+- Good: "Query engine rewritten; benchmark suite runs in 0.6s vs 4.3s previously (`bench/queries.bench.ts`)."
+
+Cut **adverbs and superlatives** unless you can prove them: "much faster", "significantly improved", "greatly enhanced" - delete or replace with a measured number.
+
+Keep entries **short by default and long where they earn it**. A bug fix that affects one endpoint is one line. A breaking change with a migration script is a block. Mismatch is the signal something is wrong - a three-paragraph bug fix usually contains a hidden breaking change; a one-line breaking change usually has a missing migration path.
+
+## Version Surfaces
+
+Every release that bumps the version must update every surface that names it:
+
+- `package.json` / `pyproject.toml` / `Cargo.toml` / the equivalent
+- `CHANGELOG.md` entry header
+- README install snippet (if it pins a version)
+- Manifest or config files that embed the version
+- Frozen snapshots (if the project uses them per ADR or convention)
+
+Mismatch between any two surfaces is a debt every user pays. Preflight or a versions-check script should enforce; manual edits are too easy to miss.
+
+## Antipatterns
+
+Each of these has cost a downstream user a real upgrade-day surprise. Don't write them; if you see them in an existing entry while you're already editing, fix.
+
+- **Commit-by-commit dumps.** "fix: corrected typo / chore: bump dep / refactor: split file" - this is `git log`, not a changelog. Theme and summarise.
+- **"Various fixes and improvements."** Either name them or omit. This phrase guarantees an upgrade-day regression nobody can map back to a documented change.
+- **"See git log for details."** The reader either has the git log (and didn't need your entry) or doesn't (and you've shipped nothing). Pick a third option: write the entry.
+- **Marketing without numbers.** "Blazing fast" / "revolutionary" / "production-ready" - the reader cannot verify any of those. Show the benchmark, the prior limitation, the new guarantee.
+- **Missing breaking changes.** A break that ships without a `BREAKING:` marker is the single most expensive changelog defect. Reviewers MUST scan for default-value changes, removed flags, signature changes, dropped runtimes, dropped browsers, changed response shapes.
+- **Stale `Unreleased` section.** If using Keep a Changelog, the `Unreleased` section MUST be empty after a release tag. A non-empty `Unreleased` after release is a process bug.
+- **Misclassified semver.** PATCH with a breaking change. MAJOR with no breaks. Spec mismatch between the bump and the content is debt every user pays.
+- **Same change in two places.** A bug fix listed under **Fixed** and again under **Changed** reads as two separate releases of work. Cross-reference instead.
+- **Stripped-out reasons.** "Removed the old caching layer" without "because it leaked memory on workers >2GB" tells the user nothing about whether they will be affected.
+- **Tombstone entries.** "Cleanup: removed deprecated code." The reader cannot tell whether anything they use was deprecated. Name what was removed.
+- **Version-mismatched surfaces.** `package.json` says 1.7.1, `CHANGELOG.md` tops out at 1.6.4, README says 1.9.0. Every release should bump every version surface; preflight should enforce.
+- **Entries for the wrong audience.** Internal-only refactor entries in a user-facing release surface. Either omit, or move to an internal "engineering notes" file with a different audience contract.
+- **Deprecation without a removal version.** "Will be removed in a future release" is a future surprise. Name the target version.
+
+## Verification Gate
+
+Before tagging a release or merging the changelog diff, walk these checks:
+
+1. **Every user-visible change in the diff is represented in the entry.** Run `git diff <prev-tag>..HEAD --name-status` and check off each surface that changed. Files that changed without a corresponding entry are either internal-only (note it) or missing from the changelog (fix it).
+2. **Every claim in the entry is verifiable from the code.** Each entry should either name a file/anchor or be obviously checkable. Bare claims age into folklore.
+3. **The semver bump matches the entry content.** Breaking change present → MAJOR. New feature only → MINOR. Fix-only → PATCH. Mismatch means either the bump or the entry is wrong.
+4. **Every breaking change has a `BREAKING:` marker and a migration path.** Before/after, or a codemod link, or a script. "Update your scripts" alone is not a migration path.
+5. **Every deprecation has a target removal version.** "Will be removed" alone is a future-bug.
+6. **No marketing without numbers.** "Faster", "improved", "better" - cut or replace with the measurement.
+7. **No stale `Unreleased` section.** If using Keep a Changelog, the `Unreleased` section is empty after the release tag.
+8. **Every version surface names the same version.** `package.json`, `CHANGELOG.md` header, README install snippet, manifest files, frozen snapshots if applicable.
+9. **Each category contains only entries that match its mental model.** Bug under **Fixed**, new feature under **Added**, etc. - reclassify before merging.
+
+If any check fails, fix before publishing. Each one has been the root cause of a downstream upgrade incident on some project.
+
+## Troubleshooting
+
+**The diff is huge and I don't know where to start.** Read `--stat` first to find the heaviest-changed areas; those usually anchor the marquee themes. New files added often signal a new feature; large deletes often signal a removal or rewrite. Use commit messages last, as one signal among several.
+
+**I can't tell if a change is breaking.** It probably is. Default-value changes, removed flags, signature changes, response-shape changes, dropped runtimes, dropped browsers, changed error codes - all break callers. If you have to argue it isn't breaking, treat it as breaking until a contract test proves otherwise.
+
+**A change shipped but the PR that introduced it had a misleading title.** The diff is the source of truth, not the title. Write the entry from what shipped.
+
+**A change was reverted before release.** Don't list it. The revert is "no change shipped" for users, even if the log shows both the add and the revert.
+
+**Two contributors added the same change under different categories.** Pick the category that matches the user's mental model (see Categories), keep one entry, delete the other, leave a cross-reference if helpful.
+
+**The entry feels too long.** It probably has commit-shaped bullets that should collapse into themes. Re-cluster by user impact; each cluster becomes one bullet.
+
+**The entry feels too short.** Either the release truly was small (fine - say so), or the writer relied on commit subjects and missed the actual scope. Walk the diff again.

+# Observability
+
+Use this when instrumenting application code with logs, metrics, span events, or trace context - i.e. adding signals that humans and dashboards will consume to answer *what happened, where, and why does it matter?*. Covers severity discipline, structured fields, naming, cardinality budget, sensitive-data rules, and the log-vs-metric-vs-span-event decision.
+
+This playbook is OpenTelemetry-shaped - instrument kinds, severity numbers, semantic attribute names, and trace correlation rules all follow the OTel data model - but the discipline applies to any backend that ingests structured logs and metrics.
+
+## Availability Check
+
+This is a discipline reference, not a runnable tool. Load it when:
+
+- Adding the first log or metric to a new service, worker, job, or endpoint.
+- Reviewing a diff that adds or changes instrumentation.
+- A postmortem reveals an instrumentation gap (logs missing context, metric explosion, severity confusion, broken trace correlation).
+- A dashboard query, alert rule, or trace lookup keeps returning unusable signal.
+
+No CLI check applies; correctness is verified at review time using the **Verification Gate** below, not by running a command.
+
+## Boundary
+
+| Concern | In this playbook | Lives elsewhere |
+|---|---|---|
+| What to emit, at what severity, with what fields | yes | - |
+| Metric and attribute naming, units, cardinality | yes | - |
+| Log vs metric vs span event vs trace decision | yes | - |
+| Distributed trace context propagation (W3C traceparent, baggage) | brief - see "Trace correlation" | OTel SDK + transport docs |
+| Sampling policy (head, tail, ratio) | no | OTel sampler docs + service-level decision |
+| Backend storage, retention, alert routing | no | operations runbook |
+| Profiling (CPU, memory, allocations) | no | profiler tooling for the runtime |
+
+If the task is sampling or propagation, this playbook only frames the requirement; the implementation lives in the SDK docs.
+
+## What a Good Log Looks Like
+
+A good log answers *what happened, where, and why it matters* without forcing the reader to cross-reference another system. Three properties:
+
+1. **Structured.** Variable data lives in attributes, not interpolated into the message. The message is a stable, searchable label; attributes carry the specifics.
+2. **Contextual.** Carries enough identifying fields (entity IDs, operation, outcome) to be actionable on its own.
+3. **Severity-honest.** Severity reflects who needs to act and how soon, not the author's emotional reaction.
+
+### Structured fields, not interpolated strings
+
+Bad (pseudocode):
+
+```
+logger.error("Failed to process payment for order " + orderId
+             + " by user " + userId + ": " + exception.message)
+```
+
+Good (pseudocode):
+
+```
+logger.error("Payment processing failed", {
+    order_id:        orderId,
+    user_id:         userId,
+    payment_gateway: gateway,
+    amount_cents:    amountCents,
+    currency:        currency,
+    error:           exception.message,
+    error_class:     typeName(exception),
+})
+```
+
+The message stays constant across thousands of failures; the attributes vary. A single log query can now group every payment failure and break it down by gateway, currency, or error class.
+
+### Trace correlation
+
+When a log is emitted inside an active span through an OTel-aware logger, the SDK attaches `trace_id`, `span_id`, and `trace_flags` to the log record. This is what makes a log reachable from a trace and a trace reachable from a log. Consequences:
+
+- **Background jobs, queue consumers, and scheduled tasks must start their own root span** before emitting logs. Otherwise their logs have no trace context.
+- **Long-running operations should emit logs inside the same span** rather than opening a fresh span per log. Many short, unrelated spans destroy the trace.
+- **Plain stdout loggers that bypass the OTel logs pipeline** will not get correlation for free; they need explicit context injection at the call site.
+
+### Enough context to act on the log alone
+
+The reader is often an on-call engineer at 3am with no project context. Include identifiers for every relevant entity, the operation attempted, and the outcome. If reading the log requires opening another system to be useful, it is missing fields.
+
+## Severity Contract
+
+Severity is a filtering contract - downstream alert rules, dashboard panels, and on-call paging depend on it. Pick deliberately, not by feel.
+
+| Level | OTel severity | Use for | Do not use for |
+|---|---|---|---|
+| `TRACE` | 1–4 | Step-by-step execution detail during local debugging | Anywhere outside an explicit debugging session |
+| `DEBUG` | 5–8 | Internal state to aid diagnosis when a flag is on | Anything kept on by default in production |
+| `INFO` | 9–12 | Normal operational events (startup, work-unit complete, config loaded) | Per-iteration loop output, hot-path traces |
+| `WARN` | 13–16 | Unexpected-but-recovered; deprecated path used; fallback triggered; degraded mode entered | Routine success; user-caused validation failures |
+| `ERROR` | 17–20 | A specific operation failed and warrants follow-up | Validation errors (downgrade to WARN); retries that succeeded |
+| `FATAL` | 21–24 | Component failure affecting many operations; process exit imminent | A single failed request or job |
+
+Two failure modes to watch for:
+
+- **Over-logging at INFO and ERROR.** If a log always fires and always reads the same, it carries no information - remove it or move it to DEBUG behind a flag.
+- **Under-logging at WARN.** Warnings are the early signal: degraded behaviour that hasn't yet failed. A service that emits only INFO and ERROR is blind to drift.
+
+## Log vs Metric vs Span Event
+
+> **Measure over time → metric. Diagnose a specific event → log. Annotate the trace timeline → span event.**
+
+| Need | Signal | Why |
+|---|---|---|
+| Alert on a rate, drive autoscaling, build a dashboard panel | Metric | Aggregable across instances without scanning raw data |
+| Investigate one specific failed request, job, or transaction | Log | Carries high-cardinality identifiers and a full attribute set |
+| Mark a point of interest inside an active trace (`retry`, `cache_miss`, `fallback_used`) | Span event | Stays attached to the parent span; doesn't pollute the log stream |
+| Capture a high-cardinality dimension (request ID, user ID, query hash) | Log or span attribute | Metric labels would explode the time-series count |
+| Report a count, duration, size, or in-flight gauge | Metric | Backends store these in O(1) per unique label combination |
+
+### The canonical pattern: emit both
+
+Failures usually want **both** a log (the detail) and a metric (the rate):
+
+```
+logger.error("Payment processing failed", {
+    order_id:        orderId,
+    payment_gateway: gateway,
+    error:           exception.message,
+    error_class:     typeName(exception),
+})
+
+meter.counter("svc.payment.failures").add(1, {
+    gateway: gateway,         // low cardinality: a handful of gateways
+    reason:  classify(exception), // low cardinality: enumerated reasons
+})
+```
+
+The log answers "why did *this* payment fail"; the counter answers "what is the failure rate by gateway right now". Neither replaces the other.
+
+## Naming Conventions

+### Metric names
+
+Structure: `<namespace>.<domain>.<subject>.<measurement>`
+
+Examples using the generic `svc.` namespace: `svc.payment.failures`, `svc.credit.usage.count`, `svc.api.requests.duration`, `svc.messenger.queue.depth`.
+
+Rules:
+
+- Lowercase, dot-separated. No hyphens, no internal underscores in path segments.
+- The leading namespace marks metrics as application-owned. Use `svc.` as a generic default, or replace it with your service or org prefix (for example, `billing.` or `acme.`) so app-owned metrics do not collide with infrastructure or third-party signals.
+- When working in a target project, check `.goat-flow/patterns/observability.md` if it exists; it may define project-specific namespaces, metric prefixes, or label conventions that override the generic examples here.
+- **Encode variable dimensions as labels, not in the name.** `svc.payment.failures` with `gateway=stripe` - never `svc.payment.stripe.failures`.
+
+### Instrument type and suffix
+
+| Instrument | Suffix convention | Example |
+|---|---|---|
+| Counter (monotonic) | `.count` or an implied noun | `svc.payment.failures`, `svc.sms.sent.count` |
+| Gauge (sampled value, callback-driven) | `.current` or descriptive noun | `svc.worker.threads.current`, `svc.queue.depth` |
+| Histogram (distribution) | `.duration`, `.size`, `.latency` | `svc.api.request.duration`, `svc.upload.size` |
+| UpDownCounter (signed delta) | descriptive noun | `svc.credit.balance`, `svc.active.sessions` |
+
+### Units
+
+Always declare the unit on the instrument (`ms`, `s`, `By`, `{requests}`, `{threads}`). Use UCUM where possible - it is what the OTel spec assumes. Unit mismatches between dashboards and instruments are the most common silent-misread bug; declare once, never assume.
+
+### Attribute and label names
+
+| Context | Convention | Example |
+|---|---|---|
+| Metric labels | `lowercase_snake_case`; finite, known cardinality | `gateway`, `outcome`, `reason`, `http_method` |
+| Log attributes | `lowercase_snake_case`; prefer OTel semantic names | `exception.type`, `exception.message`, `http.response.status_code` |
+| Custom resource or span attributes | `<namespace>.<name>` | `svc.region`, `svc.tenant_id`, `svc.cluster_id` |
+
+Prefer OTel semantic conventions (`http.*`, `db.*`, `messaging.*`, `exception.*`, `service.*`) over ad-hoc names - backends, integrations, and other readers already know what they mean.
+
+## Cardinality Budget
+
+Every unique combination of metric label values creates a new time series. Cost (memory, ingest, query latency) scales with the cross product, not the sum.
+
+Rules of thumb, in order:
+
+1. **Hand-enumeration test.** If you cannot list the possible values for a label on a napkin, it is too high-cardinality for a metric label. Move it to a log or span attribute.
+2. **Bounded enumerations only.** Acceptable labels look like `gateway` (3–10 values), `outcome` (`ok` / `failed` / `degraded`), `reason` (a known list), `http_method`, status class. Yes.
+3. **Identifiers, free text, timestamps.** Request ID, user ID, full error message, query string, IP address - **never** as a metric label. These belong on the log record.
+4. **When you need both granularities,** keep the metric label bounded (`error_type=gateway_timeout`) and put the specific identifier on the log (`error.message`, `request.id`). Connect them via `trace_id`.
+
+Anti-pattern:
+
+```
+meter.counter("svc.payment.failures").add(1, {
+    error: exception.message,    // Every distinct message creates a new time series
+})
+```
+
+Fix:
+
+```
+meter.counter("svc.payment.failures").add(1, {
+    error_type: classify(exception), // Bounded set: timeout, network, declined, ...
+})
+logger.error("Payment processing failed", {
+    error:       exception.message,   // Full text lives here
+    error_class: typeName(exception),
+})
+```
+
+## Sensitive Data
+
+Logs, traces, and metrics routinely become evidence in incidents, audits, and security reviews. Treat them as if they will be read by people outside the engineering team.
+
+| Category | In logs / traces / metric labels? | Acceptable proxy |
+|---|---|---|
+| Secrets (passwords, tokens, API keys, signed cookies) | Never | `has_token: true`, `auth_method: "bearer"` |
+| Government IDs (national ID, tax, health identifiers) | Never | Internal opaque ID |
+| Payment instruments (PAN, CVV, full card) | Never | Last 4 digits, tokenised reference |
+| PII fields without an approved storage path | No | Internal opaque ID |
+| Free-text user input | No (likely to embed PII) | Length, hash, or a classified type field |
+| Internal IDs (account, tenant, user, request) | Yes, within policy | - |
+| Operation names, route shapes, status codes, durations | Yes | - |
+
+Redact at the boundary where the value is first introduced. Trusting every downstream caller to redact is how leaks happen. Where you can, shape the field so only a sanitised value fits - `auth_method` accepting an enum, not a credential - so the type system enforces what discipline cannot.
+
+## Anti-Patterns
+
+- **Interpolated message strings.** Defeats grouping and indexing. Use structured attributes.
+- **Severity by feeling.** A validation failure is not `ERROR`. A 4ms query is not `WARN`. Pick by who needs to act and how soon.
+- **Metric label explosion.** See cardinality rules. The only safe label values are ones you can list from memory.
+- **Logs without a span.** Background jobs and consumers that emit logs without first starting a root span produce untraceable records. Start a span at the work-unit boundary.
+- **Logs as metrics.** Parsing logs at query time to derive a rate is fragile and expensive. Emit the counter from the application instead.
+- **Hot-loop logging.** A log inside a 10k-iteration inner loop is a self-inflicted incident. Aggregate, then emit one summary at the end.
+- **Double-logging the same error.** A wrapper logs the exception, the caller catches and re-logs it. The reader thinks two things happened. Catch and rethrow; log once at the boundary that has the context.
+- **Conditional severity** (`logger.log(level=isInternalCaller ? WARN : ERROR, ...)`). Suggests severity is not load-bearing for either path. Pick one or split the events.
+- **Renaming live metrics in place.** Dashboards, alerts, and saved queries reference the old name silently. Treat metric names as a public API: deprecate, dual-emit, then remove.
+- **Adding a metric without naming the dashboard or alert it serves.** If you cannot name the consumer, you probably do not need the metric.
+
+## Verification Gate
+
+Before claiming new instrumentation is done, demonstrate it does what the reader expects.
+
+1. **Logs:** find the new log in the backend by message and one expected attribute. Confirm `trace_id` is present, or note explicitly that the call site has no active span and why.
+2. **Metrics:** confirm the metric appears with the expected label set and unit. Increment it in a test run and watch the value move. For histograms, verify bucket boundaries cover the expected range.
+3. **Cardinality:** for each new label, list the possible values. If the list is open-ended, the design is wrong - fix before merging.
+4. **Consumer named:** state the dashboard panel, alert rule, or runbook step this signal exists to serve. If you cannot name one, reconsider whether it should exist.
+5. **Sensitive-data grep:** before merging, grep the diff for any field name in the sensitive-data table. Catching this in review beats catching it in a compliance audit.
+
+Verification is the difference between "I added a log" and "I added a useful log". The first is trivial; only the second pays off.

+# Release Notes
+
+Use this when writing a per-release narrative aimed at end users: a GitHub release body, a blog post, a marketing email, an in-app "what's new" banner, or any surface where the audience needs to know *why this release matters to them*. This playbook covers HOW to source themes from the changelog, the user-impact lens for prioritising what to highlight, and how to tailor depth across multiple surfaces without contradicting the source.
+
+For the durable in-repo `CHANGELOG.md` discipline (categories, SemVer alignment, write-at-commit cadence, breaking-change markers), see the sibling [`changelog.md`](./changelog.md). The changelog is the source of truth; release notes are a derived view.
+
+## Availability Check
+
+This is a discipline reference, not a runnable tool. Load it when:
+
+- Drafting a GitHub release description, blog post, email, or in-app "what's new" surface.
+- Composing a release announcement for Slack / Discord / social / internal stakeholders.
+- Reviewing release notes a teammate drafted before publish.
+- A user asks "what's new in vX.Y.Z?" and the existing announcement is too thin to answer.
+
+No availability command applies (the discipline ships with the playbook, not a tool). Some projects have a validation harness that catches a subset of release-notes defects automatically - draft-file shape checkers, version-mention parity scripts, broken-link detectors. When those exist, run them; they catch mechanical errors but not the substantive ones this playbook protects against, so they augment the **Verification Gate** below, they do not replace it.
+
+## Intent
+
+An end user opens release notes to answer one of three questions:
+
+1. **Should I upgrade?** What do I get if I do, what will break if I do.
+2. **Why should I care about this release?** I am evaluating the project and want to know if this release moves it toward or away from my use case.
+3. **What is the headline change?** I am a downstream consumer who can only spend 30 seconds on this; tell me what matters.
+
+If your release notes do not answer one of those for someone who has never read your commit history, they are not yet release notes - they are an extract of the changelog with the framing removed.
+
+The customer is a future reader who has none of your context. They cannot read your `CHANGELOG.md` in full, your PR descriptions, or your internal Slack. They have your release notes - and that may be all they read before deciding to upgrade or skip.
+
+## Changelog vs Release Notes
+
+Two artefacts, related but distinct. Get them confused and you'll write either a wall of marketing or an unreadable ledger.
+
+| | `changelog.md` (the file) | Release notes (this playbook) |
+|---|---|---|
+| Surface | `CHANGELOG.md` in repo | GitHub release body, blog post, email, in-app banner, social |
+| Audience | Contributors, downstream maintainers, dependabot, humans diffing versions | End users, evaluators, decision-makers, downstream consumers |
+| Lifetime | Permanent, append-only | Per-release; sometimes the same content as the changelog plus framing |
+| Voice | Factual, structured, terse | Narrative-allowed, prioritised, can include a "highlights" reel |
+| Required | Yes - every release | Sometimes - small patches may not warrant a separate write-up |
+| Source of truth | Yes | No - sources from the changelog |
+| Categories | Strict (Added / Changed / Fixed / etc.) | Loose (Highlights / Breaking changes / Other) |
+| Length | Full, complete | Tailored per surface (3 bullets to 1500 words) |
+
+If you only have time for one, write the changelog entry per [`changelog.md`](./changelog.md). Release notes can be derived from a good changelog; the inverse is much harder.
+
+**Release notes that contradict the changelog are a bug.** Tailoring depth is allowed; tailoring facts is not. If the email says "no breaking changes" and the changelog lists one, you have shipped a documentation incident.
+
+## Audience First
+
+Different release-notes surfaces serve different audiences. The same release ships through multiple surfaces, tailored:
+
+| Surface | Reader | Optimised for | Length |
+|---|---|---|---|
+| GitHub release body | Devs upgrading the dependency | Same content as changelog plus install snippet; markdown-rendered | Mirror changelog plus install |
+| Blog post | Evaluators, late adopters, integrators | One or two themes deep with code examples; story of why this matters | 500-1500 words |
+| Marketing email | Existing users on the announce list | Highlights + link to full notes | 3-5 bullets max |
+| In-app "what's new" | Existing users inside the product | One headline change + a link | 1-2 sentences |
+| Social (Twitter / Mastodon / Bluesky) | Wider community, casual interest | One headline + link | 1 sentence |
+
+The rule: **tailor depth, not facts**. A short surface omits items; it does not contradict the long surface.
+
+For multi-surface publishing, write the changelog entry first as the source. Then derive each release-notes surface by selecting and reframing - never by re-summarising from memory.
+
+## Source: the Changelog, Not Memory
+
+Release notes sit at the bottom of a four-link chain. Each link feeds the next; skipping a link is how facts get lost or invented.
+
+```
+diff  →  changelog (per changelog.md)  →  long-form release notes (full GitHub release / blog post)  →  shorter surfaces (email / in-app / social)
+```
+
+- **Diff repairs the changelog.** Walk the actual code changes; do not trust commit subjects (see [`changelog.md`](./changelog.md)).
+- **Changelog feeds the long-form release notes.** Theme, prioritise, add user-impact framing - but every release-notes claim must trace back to a changelog entry.
+- **Long-form release notes feed the shorter surfaces.** The email, in-app banner, and social post select from the long form by reducing depth; they never re-summarise from memory.
+
+If a release-notes claim cannot be traced back to a changelog entry, one of three things is true:
+
+1. The changelog is missing the entry - fix the changelog first (which means going back to the diff), then write the release-notes line.
+2. The release-notes claim is wrong - cut it.
+3. The release-notes claim is internal-only (refactor, perf without user-visible effect) and does not belong in user-facing notes - cut it.
+
+If the project does not have a changelog yet, fix that first (see [`changelog.md`](./changelog.md)). Writing release notes without a changelog forces every reader to take your summary on faith, with no audit trail.
+
+## Theme Identification
+
+Group changes into user-facing themes, not by file or by commit. A theme is a cluster of changes that serve the same user need, even if they touched unrelated parts of the code.
+
+How to find themes:
+
+1. **Cluster by user-visible effect.** Three changelog entries that all unblock the same use case → one theme.
+2. **Cluster by surface.** Five entries touching the same external API → one theme even if they fix different things.
+3. **Cluster by reason.** "We had to do this because compliance" - one theme, regardless of file count.
+4. **Split when audiences differ.** A perf fix and an API addition can both be "performance" - but only if a user reads them as one improvement. Otherwise split.
+
+Bad themes (signal that you're still entry-listing):
+- "Refactoring." Nobody installs a release to get refactoring.
+- "Various fixes." Either name them or leave them out.
+- "Code quality." Same.
+
+Good themes (signal that you understood the user impact):
+- "Windows compatibility" - regardless of how many files contributed.
+- "Faster cold start" - even if the work spanned three subsystems.
+- "Stricter input validation on the upload endpoint" - even if the diff is small.
+
+A useful test: can a user reading only the theme name decide whether to read further? If not, it is not yet a theme; it is a category.
+
+For a release with many themes, lead with the **highlight reel** - the 3-5 marquee items that pass the "would a stranger care?" test. Everything else is supporting detail.
+
+## The User Impact Lens
+
+Every release-notes line should pass the "so what" test. Read it as a stranger and ask "why should I care?" If the answer requires reading the changelog, rewrite for this surface.
+
+Bad:
+```
+- Refactored auth middleware.
+```
+The reader has no idea whether this is risk, opportunity, or noise.
+
+Good:
+```
+- **Single sign-on now works across subdomains.** The auth middleware was setting the cookie to the exact host rather than the parent domain. Users who left one subdomain and arrived at another were treated as logged out.
+```
+The reader knows what changed (effect), the symptom that proves it (so they can recognise prior pain), and roughly where (mechanism) - without needing to read the source.
+
+Order each line as **effect first, then mechanism**. The effect is what the reader is searching for; the mechanism is the evidence that the effect is real. In long-form surfaces (blog post, full release body), the mechanism can include a file/anchor pointer so curious readers can navigate. In short surfaces (email, social), drop the mechanism and link to the full notes.
+
+## Inverted Pyramid
+
+Release notes use an inverted pyramid: most important first, supporting detail later, internal-only or marginal items omitted.
+
+A typical release-notes structure:
+
+1. **Headline** (one sentence): the most important user-facing change.
+2. **Highlights** (3-5 bullets): marquee items that pass the "would a stranger care?" test.
+3. **Breaking changes** (if any): top billing immediately after highlights; full migration path.
+4. **Other notable changes**: secondary improvements, bug fixes worth calling out, deprecations.
+5. **Upgrade instructions**: how to install, what to check after upgrade, where to file issues.
+6. **Acknowledgements** (optional): contributors, reporters, downstream maintainers who helped.
+
+Resist the urge to list everything from the changelog. The changelog is for completeness; release notes are for prioritisation. A 30-bullet release-notes post is a sign that the writer copy-pasted the changelog instead of selecting.
+
+## Breaking Changes
+
+Breaking changes get top billing in release notes - higher than they appear in the changelog. The changelog sorts by category; release notes sort by user impact, and "this will break your code" is the highest impact.
+
+For every breaking change called out in release notes:
+
+1. **Lead with the impact** ("`--legacy-format` no longer works") not the cause ("we removed a flag").
+2. **Show before / after** code, config, or command - not prose-only descriptions.
+3. **Estimate effort** if non-trivial ("most users replace one CLI flag; CI pipelines using the long form are unaffected").
+4. **Link to migration tooling** if any (codemod, script, doc).
+5. **Reference the deprecation entry** that preceded it, so users who saw the deprecation can connect the two.
+
+If the changelog has a `BREAKING:` marker that release notes don't surface, you have buried a landmine. Every breaking change in the changelog should appear in user-facing release notes for at least the GitHub release body and the announcement email.
+
+## Voice and Specificity
+
+Release notes can be more narrative than the changelog, but the underlying rules still apply:
+
+- **Active voice.** "We added X" / "X was added" → "Added X".
+- **Specific names.** "Improved the dashboard" → "Plans view now reads `.goat-flow/tasks/`".
+- **No marketing without numbers.** "Blazing fast" → "0.6s vs 4.3s previously" (or cut the claim).
+- **No internal jargon.** "Refactored the orchestrator's reconciliation loop" → "Fewer duplicate webhook deliveries during partial outages".
+- **No hedging.** "Should be faster" / "Might fix" / "Generally works" - either it shipped or it didn't. If you have to hedge, the change is not ready for release notes.
+
+Release notes can be **longer than the changelog entry for the same change** when the audience needs context the changelog reader already has. A blog post can spend two paragraphs on a single feature; the changelog gives it one bullet. Both are correct for their surface.
+
+Release notes can also be **shorter than the changelog** for a surface like a tweet or in-app banner. Tailoring depth is allowed; omitting breaking changes is not.
+
+## Antipatterns
+
+Each of these has cost a real release a real upgrade-day surprise. Don't write them; if you see them in a draft you're reviewing, fix.
+
+- **Changelog dumps.** Copy-pasting the changelog into the GitHub release body without selection or framing is "release notes" only in the sense that it ships during a release. The reader gets no signal about what matters.
+- **Marketing-only release notes.** "We're thrilled to announce" with no specifics. The reader cannot upgrade off enthusiasm.
+- **Missing breaking changes.** A break that appears in the changelog but not the announcement email is a planted landmine. Reviewers MUST scan for `BREAKING:` markers and confirm each one appears in every user-facing surface.
+- **Contradicting the changelog.** "No breaking changes in this release" while the changelog lists a `BREAKING:` entry. Single source of truth violation.
+- **Vague upgrade instructions.** "Update and enjoy" - what about migrations, deprecations, side effects? Either name them or link to the changelog.
+- **Wrong-audience jargon.** Naming internal subsystems (`HookRouter`, `ResolverV2`) in an end-user email. Internal names are signals, not communication.
+- **Highlights that aren't highlighted.** Burying the marquee change in bullet 12 because the writer worked through the changelog in order instead of prioritising.
+- **Future-vague.** "Coming soon", "in a future release", "we're working on" - these belong on a roadmap, not in release notes for what just shipped.
+- **Acknowledgement padding.** Listing every contributor's name when the audience is end users; reserve acknowledgement sections for surfaces where it earns its place (GitHub release body, dev-targeted blog post).
+- **Stale numbers.** "100x faster than version 1.0" - over multiple releases this becomes meaningless. State the baseline and the measurement that proves the claim.
+- **Missing publication metadata.** Release notes without a version, date, or link to the install instructions force the reader to do extra work to act on what they just read.
+
+## Multi-Surface Consistency
+
+When publishing across multiple surfaces, treat the long form (full release body or full blog post) as the source. Derive shorter surfaces from it by selecting, never by re-summarising from memory.
+
+A practical workflow:
+
+1. **Write the changelog entry.** This is the structural source of truth - see [`changelog.md`](./changelog.md).
+2. **Write the full release body** (GitHub release / blog) using the changelog as input. Theme, prioritise, add user-impact framing.
+3. **Derive the email** by selecting the highlights + link to the full release body.
+4. **Derive the in-app banner** by selecting the single headline + link to the full release body.
+5. **Derive the social post** by selecting the single headline as a one-liner.
+
+Each derivation reduces depth; none should contradict the source. If the email omits a breaking change because of length, that omission is the bug - either include it (length be damned) or pull the email back to "Read the release notes for migration details".
+
+## Cadence
+
+Release notes are written at release time, not at commit time. Even projects that use the `Unreleased` changelog cadence (see [`changelog.md`](./changelog.md)) write release notes after deciding to cut a version.
+
+A practical timeline (compress to one sitting for fast-iteration or solo projects; the steps are the same, only the wall-clock changes):
+
+1. **Pre-tag:** review the `Unreleased` section or diff against the prior tag. Identify themes. Draft the release-notes outline.
+2. **Tag:** if the project uses write-at-commit cadence per [`changelog.md`](./changelog.md), fold the `Unreleased` section into the new version header at this step - the changelog text is already written, this step renames the heading and dates it. If the project uses write-at-release cadence, write the changelog entry now. Either way, write the GitHub release body next, mirroring the changelog plus install instructions.
+3. **Post-tag:** publish derived surfaces (blog, email, social, in-app) using the release body as source.
+
+Resist publishing release notes before the tag. A tag that doesn't match the published narrative is hard to fix without confusing readers who already acted on the early notes.
+
+## Verification Gate
+
+Before publishing release notes on any surface, walk these checks:
+
+1. **Every claim traces to a changelog entry.** If a release-notes line cannot be mapped back to the changelog, either fix the changelog or cut the line.
+2. **Every breaking change in the changelog appears in user-facing notes.** Highest user impact gets top billing - never bury or omit.
+3. **The headline change passes the "would a stranger care?" test.** Read it as someone who has never seen the project. If the answer is "I don't know what this is", rewrite.
+4. **No marketing without numbers.** "Faster", "better", "improved" - cut or replace with the measurement.
+5. **No wrong-audience jargon.** Internal subsystem names, refactor descriptions, code-shape claims - cut for end-user surfaces, keep for dev-audience surfaces.
+6. **Multi-surface variants do not contradict each other.** The email's "no breaking changes" must not contradict the release body's `BREAKING:` entry.
+7. **Upgrade instructions are concrete.** Install command, migration path, where to file issues.
+8. **Version, date, and install location are present.** A reader landing on the page should not have to search for which version this is for.
+9. **A reader who has never seen this project can decide "should I upgrade?"** from the release notes alone. If they can't, the notes are still a working memo.
+
+If any check fails, fix before publishing. Each one has been the root cause of an upgrade-day incident on some project.
+
+## Troubleshooting
+
+**The changelog is thin and I can't draft release notes from it.** Fix the changelog first per [`changelog.md`](./changelog.md). Release notes derived from a thin changelog will be either wrong or fluffy.
+
+**A reviewer wants more themes than the diff supports.** Don't invent themes to fill space. A small release gets short release notes; that is the correct outcome. Padding is a tell.
+
+**A reviewer wants fewer themes than the diff requires.** Don't drop breaking changes or material user-facing changes for narrative tidiness. If the release truly is broad, the notes are broad; pick the highlight reel and keep the rest as "Other notable changes".
+
+**Marketing wants a different headline than the engineering changelog suggests.** Pick the user-impact framing, not the technical framing. "Faster cold start" is correct even if engineering thinks of it as "rewrote the asset bundler". Both can be true; release-notes voice picks the user-visible one.
+
+**Two breaking changes have different migration paths.** Keep both in the breaking-changes section, each with its own before/after. Do not merge into a single "various migration changes" bullet.
+
+**The release-notes draft contradicts the changelog.** The changelog wins. Fix the release notes; don't fix the changelog to match a draft.
+
+**A change shipped without a changelog entry.** Add the changelog entry first (retroactively, in the correct version). Then write the release-notes line.
+
+**An old release notes surface is now wrong because of follow-up work.** Add a "Updated:" footer linking the follow-up release, but do not silently edit the original. Readers who acted on the original should be able to see what they saw.

+The `description:` frontmatter field decides when an agent loads the skill. It must describe **triggering conditions** ("Use when X happens"), never the skill's internal workflow ("Use when X - dispatches subagent then runs review between tasks").
 
 **Empirical observation:** workflow-summary descriptions cause the loading agent to follow the description instead of reading the body. "Code review between tasks" can cause one review when the body shows two stages. Trimming to triggering conditions restores correct skill-body following.
 
 This is a measurable failure mode, not a style preference. The deterministic scorer's `descriptionSummarizesWorkflow` check (see `src/cli/quality/skill-quality.ts`) is the in-repo signal, alongside the BAD/GOOD examples below.
 
 ```yaml
-# BAD — workflow summary in description; agent will follow this instead of the body
+# BAD - workflow summary in description; agent will follow this instead of the body
 description: "Use when executing plans - dispatches subagent per task with code review between tasks"
 
-# BAD — too much process detail
+# BAD - too much process detail
 description: "Use for TDD - write test first, watch it fail, write minimal code, refactor"
 
-# GOOD — triggering conditions only, no workflow narration
+# GOOD - triggering conditions only, no workflow narration
 description: "Use when executing implementation plans with independent tasks in the current session"
 
-# GOOD — goat-flow style
+# GOOD - goat-flow style
 description: "Use when starting a non-trivial implementation that needs structured task breakdown with progress tracking."
 ```
 
-The deterministic scorer surfaces a yellow advisory tip when the description (after stripping `Use when …`) contains procedural verbs (`dispatches`, `implements`, `executes`, `generates`, `runs`, `produces`, `creates`, `builds`, `writes`, `refactors`) or process connectives (`then`, `between`). The tip is advisory only — it doesn't deduct, so the author can judge whether the verb is genuine trigger context or workflow narration. Scorer source: `src/cli/quality/skill-quality.ts` (search: `descriptionSummarizesWorkflow`).

 5. `ConfigLoader::load()` produces an `AnalysisConfig` from the registry defaults, then overlays `.gruff-php.yaml`, legacy `.gruff.yaml`, or the explicit `--config` path; unknown root keys, invalid `minimumPhpVersion`, path ignore patterns, allowlist values, selection values, rule ids, rule keys, threshold/severity settings, threshold names, and non-numeric thresholds throw `ConfigException`, which becomes a `config-error` `RunDiagnostic`. After config loading, `--profile=security` replaces the execution `RuleSelection` with the `security` and `sensitive-data` pillars while keeping per-rule settings, path ignores, and allowlists from the loaded config.
 6. `SourceDiscovery::discover()` expands the input paths (defaulting to `.`), records missing inputs, and yields `SourceFile` values typed `php` or `text`. In Git worktrees, default discovery uses `git ls-files --cached --others --exclude-standard` as the scan boundary, then applies configured `paths.ignore` and built-in generated lockfile skips. `--include-ignored` opts back into filesystem traversal, and non-Git roots fall back to the filesystem walker with the default ignored-directory list.
 7. For each discovered file, `PhpFileParser::parse()` reads the source. PHP files are parsed by `nikic/php-parser` and decorated with a `ParentConnectingVisitor`; non-PHP text/config files short-circuit to an `AnalysisUnit` with raw source but no AST or tokens. Parse failures produce one `ParseDiagnostic` per error and are surfaced as `parse-error` `RunDiagnostic` entries.
-8. `RuleRegistry::analyse()` skips units with parse errors, then iterates rules allowed by `RuleSelection` and per-rule `enabled` settings. Two rule shapes are supported (see ADR-003): per-unit rules implementing `RuleInterface` see one `AnalysisUnit` at a time, and project rules implementing `ProjectRuleInterface` run once over the full list of parse-clean PHP units after the per-unit loop. PHP-only rules run only against `SourceFile::isPhp()` units; rules implementing `SourceTextRuleInterface` also run against text/config units, so secret/PII scanners cover JSON, YAML, env, Markdown, TOML, shell, and similar files. Overlapping naming findings on the same identifier are reduced by rule priority (`class-file-mismatch > confusing-name > negative-boolean > boolean-prefix > identifier-quality > hungarian-notation > suffix-hungarian > short-variable > abbreviation-allowlist`), then findings from all units are sorted by `(filePath, line, ruleId, message)` for deterministic output. Project rules currently power `design.single-implementor-interface`.

Project rules currently power `design.single-implementor-interface` and project-wide internal dead-code checks for classes, functions, and constants.
 9. If `--infection-report` is supplied, `InfectionReportParser` ingests the full Infection JSON report, calculates per-file mutation summaries, and `MutationFindingFactory` appends `mutation.survived-mutant`, `mutation.budget-exceeded`, and `mutation.msi-regression` findings where applicable. `--infection-run` is explicit opt-in and only shells out through `InfectionRunner`; it requires a report path because Infection controls full JSON log output through its config.
 10. If `--diff-vs=<base>` is supplied, `GitDiffProvider` reads changed files from Git and `GitArchiveSnapshot` builds a temporary base-ref snapshot without mutating the worktree. `BranchReviewComparator` compares current and base findings by `file + ruleId + symbol`, falling back to `file + ruleId + message`, and exposes introduced/removed/unchanged sets plus score delta. `--changed-only` limits both comparison sets to changed files; when no explicit paths are supplied, `analyse` uses the Git changed-file list as the current-tree analysis path list instead of first discovering the whole project. Base snapshots are path-limited before extraction by resolving candidate paths against the base ref with `git ls-tree -r --name-only`, then archiving only the matching base files. If `--diff` is supplied instead, `GitDiffProvider` reads changed files and new-line ranges from Git (`working-tree`, `staged`, `unstaged`, or a base ref), and `DiffFindingFilter` keeps only findings touching changed lines or changed files.
 11. Configured secret preview allowlists remove matching `SensitiveData` findings by redacted preview, after rules run and before scoring.

 ## Rule Catalogue
 
-The default registry-backed static rule set covers 11 emitted pillars (`Size`, `Complexity`, `Maintainability`, `DeadCode`, `Naming`, `Documentation`, `Modernisation`, `Security`, `SensitiveData`, `TestQuality`, `Design`) and currently exposes 128 rule ids through `list-rules --format json`. `waste.*` rule ids are historical names that emit either `DeadCode` or `Maintainability` findings. Infection ingestion can also emit `Mutation` pillar findings. All emitted rules are tier `v0.1`; `Coupling` and `Architecture` remain reserved.

 | Complexity | `complexity.cognitive`, `complexity.cyclomatic`, `complexity.halstead-volume`, `complexity.maintainability-index`, `complexity.nesting-depth` | `cognitive` (error @ 20) and `nesting-depth` (error @ 4) are the legibility hard-gates; `cyclomatic` is `warning`; `halstead-volume` + `maintainability-index` are `advisory`; `maintainability-index` reports on the `Maintainability` pillar |
-| DeadCode | `dead-code.unused-private-method`, `dead-code.unused-private-property` | Class-local; conservative to avoid framework/inheritance false positives |
+| DeadCode | `dead-code.unused-private-constant`, `dead-code.unused-private-method`, `dead-code.unused-private-property`, `dead-code.unused-internal-class`, `dead-code.unused-internal-function`, `dead-code.unused-internal-constant` | Private members are class-local; project-wide internal symbol checks use Composer/configured namespace ownership plus entrypoint/path/framework/test-reference escape hatches, skip test declarations as runner entrypoints, and stay advisory/medium |
 | Waste | `waste.commented-out-code`, `waste.empty-class`, `waste.empty-method`, `waste.one-line-method`, `waste.redundant-variable`, `waste.unreachable-code`, `waste.unused-import`, `waste.unused-parameter` | AST-driven; `waste.one-line-method` reports on the Maintainability pillar because it targets avoidable indirection; other waste rules report dead-code-style clutter |
 | Naming | `naming.abbreviation-allowlist`, `naming.boolean-prefix`, `naming.class-file-mismatch`, `naming.confusing-name`, `naming.generic-method`, `naming.hungarian-notation`, `naming.identifier-quality`, `naming.negative-boolean`, `naming.short-variable`, `naming.suffix-hungarian`, `naming.test-naming-consistency` | Mix of identifier conventions, placeholder/generic identifier checks, direct object-local names, abbreviation allowlisting, boolean flag shape checks, suffix/prefix Hungarian checks, and class/file alignment. Closure/arrow-capable naming rules share `FunctionLikeScopeWalker` for isolated parameter/local scopes. `naming.parameter-type-name` was retired in [ADR-014](decisions/ADR-014-retire-naming-parameter-type-name.md) |

Structural PHPDoc rules cover files, class-like declarations, properties, and constants. `docs.missing-return-tag` applies to every documented method/function except constructors/destructors. `docs.return-comment` keeps its legacy id but now flags value-returning function-like declarations whose existing `@return` tag has no description. `docs.regex-comment` requires immediate one-line context for configured regex matcher calls, defaulting to `preg_match`. `docs.missing-readme` looks at `<projectRoot>/README.md` and is independent of the unit being analysed |

Project-config rules (one finding per analyse run, read from `phpunit.xml`/`phpunit.xml.dist`/`phpunit.dist.xml`): `test-quality.phpunit-strict-flags-missing`, `test-quality.phpunit-deprecations-not-fatal`, `test-quality.phpunit-coverage-source-missing`. PHPUnit/Pest AST heuristics scoped to detected test methods or closures; confidence labels identify noisier smells; the `error` hard-gates are the "this test proves nothing" signals — `test-quality.no-assertions`, `test-quality.sut-not-called`, `test-quality.tautological-type-assertion`, `test-quality.empty-data-provider`, and `test-quality.extends-production-class` (ADR-022) — while the style/ceremony smells stay warning/advisory; `TestQualityNodeHelper` is shared infrastructure |
 | Design | `design.single-implementor-interface` | Project rule that flags internal interfaces with one implementor and no external type-hint usage |
 | Mutation | `mutation.survived-mutant`, `mutation.budget-exceeded`, `mutation.msi-regression` | Not registry-backed static rules; emitted only from optional Infection JSON ingestion |

 - **New-findings-only gate (`--fail-on-new`)** - the capstone of the coding-agent-hook workflow: fail CI only on findings the change *introduced*, freezing pre-existing debt as visible-but-non-blocking. `--fail-on-new` (shorthand for `failureConditions.newFindings.severityThresholds.error: 0`, which also accepts `severityThresholds`/`total`) gates the new set, defined as `baselineNew ∩ branchIntroduced` — the post-baseline findings when `--baseline` is set, the branch-introduced findings when `--diff-vs <ref>` is set, their intersection when both are; never "all findings". Enabling it with no reference point (no baseline and no `--diff-vs`) fails fast at setup instead of failing every finding. A new-findings trip renders distinctly (`Failed: 3 new error finding(s)…`, JSON `failureReason.scope: "new"` plus a `newFindingsCount`); the total gate and the new-findings gate fire independently, with the new-findings reason winning when both trip.
 - **Incremental result cache** - cache-eligible runs (those with no project rules — e.g. the `security` profile, or a config that excludes the design/dead-code rules) now reuse unchanged files' findings across runs via a content-addressed, gitignored `.gruff-cache/`, keyed on file bytes plus the resolved rule settings plus the gruff version. A cold cache and `--no-cache` produce byte-identical output; any content, config, or version change invalidates the affected entries; runs with project rules bypass the cache entirely (their cross-file rules need every unit). The base-ref snapshot cache for `--diff-vs` is a documented follow-up (ADR-020).
 - **Config presets and `extends:`** - bundled `gruff.recommended`, `gruff.starter`, and `gruff.strict` profiles plus an `extends:` key let a repo replace a ~560-line `.gruff-php.yaml` with a few lines — `extends: gruff.recommended`, then only your overrides. `extends:` accepts a bundled preset name (`gruff.*`) or a relative/absolute path; chains resolve ancestor-first (a child's section overrides the inherited one), cycles and chains deeper than five hops fail with a clear error naming the chain, and an unknown preset name lists the valid ones. `extends: gruff.recommended` with no overrides behaves identically to running with no config file at all, and a preset-integrity test keeps the bundled presets from drifting out of sync with the rule registry (ADR-021).
-- **BREAKING: Retired the `complexity.npath` rule** - NPath produced false positives on sequential-but-simple branching and is redundant with the cognitive, cyclomatic, and nesting metrics. Remove any `complexity.npath` block from your config (it now fails closed as an unknown rule id) and regenerate baselines to drop stale npath findings. The registry now exposes 118 rules.
+- **BREAKING: Retired the `complexity.npath` rule** - NPath produced false positives on sequential-but-simple branching and is redundant with the cognitive, cyclomatic, and nesting metrics. Remove any `complexity.npath` block from your config (it now fails closed as an unknown rule id) and regenerate baselines to drop stale npath findings. Later 0.3.0 additions bring the final registry catalogue to 132 rules.
 - **BREAKING: Retired the synthetic `design.god-method` rubric** - Size and complexity findings remain visible and scored through their native pillars, but gruff no longer appends a second design finding when they overlap on the same symbol. Remove stale `design.god-method` entries from baselines; there is no config block to migrate because the old finding was not registry-backed. The registry count is unchanged because the old finding was never registry-backed.
 - **Correlated size/complexity findings share one penalty** - a method that is long *and* deeply nested *and* cyclomatically complex is one root cause, so scoring now bills it once instead of once per symptom. Findings sharing a `(file, symbol, line)` whose rule is in `{complexity.cognitive, complexity.cyclomatic, complexity.nesting-depth, size.method-length, size.parameter-count}` contribute a single shared weight (`max(member penalty) / member count`) to both their pillar and file scores; every finding still appears in the report and its pillar count. Composite and pillar grades rise for files that previously double- or triple-counted one over-large method; a file with no co-located cluster scores exactly as before. Findings, fingerprints, and the `gruff.analysis.v2` / `gruff.baseline.v1` schemas are unchanged, so baselines keep matching — only penalty weighting and the score `explanation` string change (ADR-024).
 - **`naming.boolean-prefix` gains an `acceptedBooleanNames` allowlist** - a boolean-returning method named `valid()` could previously only be cleared by the caller-breaking rename to `isValid()`; the new `rules.naming.boolean-prefix.options.acceptedBooleanNames` exact, case-insensitive allowlist accepts a caller-visible name as-is across methods, properties, and parameters, so a finding on a public name resolves with config rather than a breaking rename. Default empty; existing scans are unchanged.
 - **Complexity recalibration** - `complexity.halstead-volume` and `complexity.maintainability-index` are now `advisory` (informational, non-gating); `complexity.cognitive` tightened to a threshold of 20 and `complexity.nesting-depth` to 4; `complexity.cyclomatic` is now `warning`. The complexity pillar now gates on the metrics that track human comprehension rather than branch-counting proxies.
 - **Test-quality gate parity** - the "tested for real" mission leg now gates. `test-quality.no-assertions` (a test with no observable assertion), `test-quality.sut-not-called` (the named subject is never invoked), and `test-quality.tautological-type-assertion` (`assertInstanceOf(X, new X)`) are promoted to `error`, so `analyse --fail-on error` fails a suite whose tests prove nothing — and the cheapest way to satisfy each is a real assertion. The cosmetic-fix and style smells (`mock-without-expectation`, `trivial-assertion`, `eager-test`, naming/readability, …) stay at warning/advisory so the gate never forces ceremony. Each promotion fires only on genuinely fake tests, not on assertion helpers, data-provider matrices, `expectException`, or Pest `expect()` (ADR-022).
 - **Config accepts `advisory` severity** - the `rules.<id>.severity` config key now accepts `advisory` alongside `warning` and `error`, so rules that default to advisory can be pinned or overridden in `.gruff-php.yaml`.
+- **Project-wide dead-code expansion** - `dead-code.unused-private-constant` catches local private constants, and new advisory project-wide rules (`dead-code.unused-internal-class`, `dead-code.unused-internal-function`, `dead-code.unused-internal-constant`) flag project-owned internal symbols that have no supported references. Composer PSR-4 prefixes or `internalNamespacePrefixes` establish ownership, and `entrypointSymbols`, path exclusions, framework attributes, and test-reference handling keep framework/API boundaries configurable. Existing baselines may gain new dead-code findings.
+- **Sensitive-data expansion** - `sensitive-data.gcp-service-account-key` detects committed service-account JSON with redacted previews, and `sensitive-data.url-credentials` covers HTTP(S) URLs with embedded credentials outside database-URL shapes. Reporter leak tests cover text, JSON, SARIF, GitHub annotations, Markdown, HTML, report, and dashboard surfaces so raw secrets stay out of output.
 - **Mission documented** - a stated project mission (governing AI-generated code for human verifiability) now anchors `README.md`, `docs/mission.md`, and the agent instructions, recorded in ADR-017.
 - **Nullable JSON-boundary bags exempt from `phpdoc-mixed-overuse`** - `modernisation.phpdoc-mixed-overuse` no longer fires on a nullable unstructured bag such as `array<string, mixed>|null` — the honest type of a `json_decode` helper that returns the decoded object or `null` — matching the existing exemption for the non-null `array<string, mixed>` form. Standalone `mixed` and concrete-keyed shapes still fire.
 - **Internal restructuring** - the `AnalyseCommand` god-object is decomposed into `AnalysisFindingSupport` and `BranchReviewBuilder` collaborators, the `--no-cache` flag moves onto `AnalyseCommandOptions`, and the `FailThresholds` / `SourceDiscovery` hotspots drop below the cognitive-complexity gate. No CLI behaviour or output schema changes.

+This project is still pre-1.0, so minor releases may break behaviour. Breaking
+changes are marked and include the action to take.
 
 ## 0.3.0 - 2026-05-31
 
-gruff-php sharpens around a single mission — governing AI-generated code so a human who didn't write it can read, verify, and trust it — and hardens its rule and schema surface while staying pre-1.0. The headline breaking change retires the noisy `complexity.npath` rule and recalibrates the complexity pillar toward the metrics that track human comprehension; changed-region analysis lands — and `paths.ignore` becomes authoritative across every scan mode — so coding-agent hooks see only the lines they touched and never the code the project deliberately excluded. A baseline-aware gate chain (three-state baseline reporting, per-severity count thresholds, and the `--fail-on-new` capstone) completes that workflow: CI can fail only on the debt a change introduces, freezing existing debt as visible-but-non-blocking.
-
-- **Changed-region analysis** - `analyse` now accepts `--changed-ranges`, `--since`, bare `--diff`, `--diff -`, and `--changed-scope=symbol|hunk` so hook consumers can request only findings attributable to the edited region. JSON reports include `suppressedCount` when this mode filters out pre-existing findings.
-- **Ignore reasons and `check-ignore`** - the JSON report's new additive `ignoredPathDetails` field records why each path was excluded — its `source` (`config`, `default`, `generated`, or `gitignore`) and matching `pattern` — alongside the existing `ignoredPaths` list. A new `check-ignore [--format text|json] [--config <path>|--no-config] <path>...` command answers whether gruff would ignore a path, and why, without running an analysis (JSON `[{path, ignored, source, pattern}]`; exit codes mirror `git check-ignore`). `paths.ignore` stays authoritative in every mode — explicit file operands and all diff/changed-region scans, not just the directory walk — and `--include-ignored` never overrides it (ADR-019).
-- **Three-state baseline reporting** - applying a baseline now classifies findings into `new` / `unchanged` / `resolved` buckets — exposed in JSON at `baseline.buckets` and as a one-line "Movement: N new, M unchanged, K resolved" summary in text, markdown, and HTML — turning the baseline from a write-only mute list into a debt-movement view. A new `--baseline-include-absent` flag lists the resolved (absent) entries in text/markdown/HTML output (off by default to keep PR comments short). The on-disk `gruff-baseline.json` and `gruff.baseline.v1` schema are unchanged.
-- **Per-severity count gates** - a new `failureConditions:` config block expresses the gate as counts — `total: <int>` and `severityThresholds: {advisory, warning, error}: <int>` — so a team can "allow up to 5 warnings, fail on any error" without committing a baseline ("allow N" passes at count ≤ N, fails above). A tripped gate prints a one-line `Failed: …` reason in text and markdown and a top-level `failureReason` (`{thresholdKind, count, cap, message}`) in JSON, so CI logs explain which threshold was exceeded. `--fail-on <severity>` is unchanged and still wins when passed explicitly; with no `failureConditions:` block the gate behaves exactly as before, and baselined findings remain excluded from the count.
-- **New-findings-only gate (`--fail-on-new`)** - the capstone of the coding-agent-hook workflow: fail CI only on findings the change *introduced*, freezing pre-existing debt as visible-but-non-blocking. `--fail-on-new` (shorthand for `failureConditions.newFindings.severityThresholds.error: 0`, which also accepts `severityThresholds`/`total`) gates the new set, defined as `baselineNew ∩ branchIntroduced` — the post-baseline findings when `--baseline` is set, the branch-introduced findings when `--diff-vs <ref>` is set, their intersection when both are; never "all findings". Enabling it with no reference point (no baseline and no `--diff-vs`) fails fast at setup instead of failing every finding. A new-findings trip renders distinctly (`Failed: 3 new error finding(s)…`, JSON `failureReason.scope: "new"` plus a `newFindingsCount`); the total gate and the new-findings gate fire independently, with the new-findings reason winning when both trip.
-- **Incremental result cache** - cache-eligible runs (those with no project rules — e.g. the `security` profile, or a config that excludes the design/dead-code rules) now reuse unchanged files' findings across runs via a content-addressed, gitignored `.gruff-cache/`, keyed on file bytes plus the resolved rule settings plus the gruff version. A cold cache and `--no-cache` produce byte-identical output; any content, config, or version change invalidates the affected entries; runs with project rules bypass the cache entirely (their cross-file rules need every unit). The base-ref snapshot cache for `--diff-vs` is a documented follow-up (ADR-020).
-- **Config presets and `extends:`** - bundled `gruff.recommended`, `gruff.starter`, and `gruff.strict` profiles plus an `extends:` key let a repo replace a ~560-line `.gruff-php.yaml` with a few lines — `extends: gruff.recommended`, then only your overrides. `extends:` accepts a bundled preset name (`gruff.*`) or a relative/absolute path; chains resolve ancestor-first (a child's section overrides the inherited one), cycles and chains deeper than five hops fail with a clear error naming the chain, and an unknown preset name lists the valid ones. `extends: gruff.recommended` with no overrides behaves identically to running with no config file at all, and a preset-integrity test keeps the bundled presets from drifting out of sync with the rule registry (ADR-021).
-- **BREAKING: Retired the `complexity.npath` rule** - NPath produced false positives on sequential-but-simple branching and is redundant with the cognitive, cyclomatic, and nesting metrics. Remove any `complexity.npath` block from your config (it now fails closed as an unknown rule id) and regenerate baselines to drop stale npath findings. Later 0.3.0 additions bring the final registry catalogue to 132 rules.
-- **BREAKING: Retired the synthetic `design.god-method` rubric** - Size and complexity findings remain visible and scored through their native pillars, but gruff no longer appends a second design finding when they overlap on the same symbol. Remove stale `design.god-method` entries from baselines; there is no config block to migrate because the old finding was not registry-backed. The registry count is unchanged because the old finding was never registry-backed.
-- **Correlated size/complexity findings share one penalty** - a method that is long *and* deeply nested *and* cyclomatically complex is one root cause, so scoring now bills it once instead of once per symptom. Findings sharing a `(file, symbol, line)` whose rule is in `{complexity.cognitive, complexity.cyclomatic, complexity.nesting-depth, size.method-length, size.parameter-count}` contribute a single shared weight (`max(member penalty) / member count`) to both their pillar and file scores; every finding still appears in the report and its pillar count. Composite and pillar grades rise for files that previously double- or triple-counted one over-large method; a file with no co-located cluster scores exactly as before. Findings, fingerprints, and the `gruff.analysis.v2` / `gruff.baseline.v1` schemas are unchanged, so baselines keep matching — only penalty weighting and the score `explanation` string change (ADR-024).
-- **`naming.boolean-prefix` gains an `acceptedBooleanNames` allowlist** - a boolean-returning method named `valid()` could previously only be cleared by the caller-breaking rename to `isValid()`; the new `rules.naming.boolean-prefix.options.acceptedBooleanNames` exact, case-insensitive allowlist accepts a caller-visible name as-is across methods, properties, and parameters, so a finding on a public name resolves with config rather than a breaking rename. Default empty; existing scans are unchanged.
-- **Complexity recalibration** - `complexity.halstead-volume` and `complexity.maintainability-index` are now `advisory` (informational, non-gating); `complexity.cognitive` tightened to a threshold of 20 and `complexity.nesting-depth` to 4; `complexity.cyclomatic` is now `warning`. The complexity pillar now gates on the metrics that track human comprehension rather than branch-counting proxies.
-- **Test-quality gate parity** - the "tested for real" mission leg now gates. `test-quality.no-assertions` (a test with no observable assertion), `test-quality.sut-not-called` (the named subject is never invoked), and `test-quality.tautological-type-assertion` (`assertInstanceOf(X, new X)`) are promoted to `error`, so `analyse --fail-on error` fails a suite whose tests prove nothing — and the cheapest way to satisfy each is a real assertion. The cosmetic-fix and style smells (`mock-without-expectation`, `trivial-assertion`, `eager-test`, naming/readability, …) stay at warning/advisory so the gate never forces ceremony. Each promotion fires only on genuinely fake tests, not on assertion helpers, data-provider matrices, `expectException`, or Pest `expect()` (ADR-022).
-- **Config accepts `advisory` severity** - the `rules.<id>.severity` config key now accepts `advisory` alongside `warning` and `error`, so rules that default to advisory can be pinned or overridden in `.gruff-php.yaml`.
-- **Project-wide dead-code expansion** - `dead-code.unused-private-constant` catches local private constants, and new advisory project-wide rules (`dead-code.unused-internal-class`, `dead-code.unused-internal-function`, `dead-code.unused-internal-constant`) flag project-owned internal symbols that have no supported references. Composer PSR-4 prefixes or `internalNamespacePrefixes` establish ownership, and `entrypointSymbols`, path exclusions, framework attributes, and test-reference handling keep framework/API boundaries configurable. Existing baselines may gain new dead-code findings.
-- **Sensitive-data expansion** - `sensitive-data.gcp-service-account-key` detects committed service-account JSON with redacted previews, and `sensitive-data.url-credentials` covers HTTP(S) URLs with embedded credentials outside database-URL shapes. Reporter leak tests cover text, JSON, SARIF, GitHub annotations, Markdown, HTML, report, and dashboard surfaces so raw secrets stay out of output.
-- **Mission documented** - a stated project mission (governing AI-generated code for human verifiability) now anchors `README.md`, `docs/mission.md`, and the agent instructions, recorded in ADR-017.
-- **Nullable JSON-boundary bags exempt from `phpdoc-mixed-overuse`** - `modernisation.phpdoc-mixed-overuse` no longer fires on a nullable unstructured bag such as `array<string, mixed>|null` — the honest type of a `json_decode` helper that returns the decoded object or `null` — matching the existing exemption for the non-null `array<string, mixed>` form. Standalone `mixed` and concrete-keyed shapes still fire.
-- **Internal restructuring** - the `AnalyseCommand` god-object is decomposed into `AnalysisFindingSupport` and `BranchReviewBuilder` collaborators, the `--no-cache` flag moves onto `AnalyseCommandOptions`, and the `FailThresholds` / `SourceDiscovery` hotspots drop below the cognitive-complexity gate. No CLI behaviour or output schema changes.
-- **`docs.return-comment` now describes `@return` tags** - the rule id is unchanged, but its contract is redefined from "one-line comment directly above every `return`" to "value-returning functions with an existing `@return` tag need prose after the type." Missing tags stay owned by `docs.missing-return-tag`, wholly tag-only docblocks stay owned by `docs.bare-phpdoc-tags`, and void/never returns plus constructors/destructors are exempt. Existing baselines may shift because the finding surface moved from return statements to the PHPDoc contract.
-- **`docs.missing-param-tag` now covers non-public methods** - the rule previously inspected only public methods; it now flags any documented method or function (private and protected included) whose docblock omits an `@param` for a parameter, matching the project's mandatory-doc-on-every-unit stance. Freeze existing private-method gaps via the baseline so the rule gates new code rather than forcing a backfill.
+0.3.0 focuses on agent-friendly CI: scan only changed code, respect ignored paths everywhere, and fail on newly introduced debt instead of old baseline debt. It also removes noisy complexity/design checks and tightens the rules that support human review of AI-written code.
+
+- **Changed-code scanning** - `analyse` can now report only findings tied to edited ranges or symbols. JSON reports say how many older findings were suppressed.
+- **Ignore handling is stricter** - `paths.ignore` now applies to explicit files, diff scans, and changed-region scans. `check-ignore` explains why a path is ignored.
+- **Better baseline reporting** - Baseline output now separates findings into `new`, `unchanged`, and `resolved`, so teams can see debt movement instead of only muting old issues.
+- **Count-based gates** - `failureConditions:` can fail a run by total finding count or by advisory/warning/error counts. Existing `--fail-on` behaviour still works.
+- **New-findings gate** - `--fail-on-new` fails only on findings introduced by the current change. It requires a baseline, `--diff-vs`, or both.
+- **Incremental cache** - Eligible runs reuse findings for unchanged files through `.gruff-cache/`. Runs that need whole-project analysis still bypass the cache.
+- **Config presets** - `extends: gruff.recommended`, `gruff.starter`, or `gruff.strict` can replace most local config boilerplate.
+- **BREAKING: Removed `complexity.npath`** - Delete any `rules.complexity.npath` config and regenerate baselines. The rule was noisy and overlapped with clearer complexity metrics.
+- **BREAKING: Removed synthetic `design.god-method` findings** - Size and complexity findings still report normally, but gruff no longer adds a duplicate design finding. Remove stale baseline entries.
+- **Fairer scoring** - Related size and complexity findings on the same method now count as one scoring penalty, while still appearing as separate findings.
+- **Boolean-name allowlist** - `naming.boolean-prefix` can now accept intentional names like `valid()` without forcing a public API rename.
+- **Complexity rules recalibrated** - Halstead volume and maintainability index are advisory; cognitive and nesting thresholds are tighter; cyclomatic complexity is warning-level.
+- **Fake-test rules are stricter** - Tests with no real assertion, no subject call, or tautological type assertions now fail at error level.
+- **Config supports `advisory`** - Rule severity overrides now accept `advisory`.
+- **More dead-code checks** - gruff can now flag unused private constants and unused project-owned internal classes, functions, and constants.
+- **More secret checks** - gruff now detects GCP service-account keys and credentials embedded in HTTP(S) URLs, with reporter tests to keep raw secrets redacted.
+- **Mission documented** - README, docs, agent instructions, and ADR-017 now state the project goal: help humans verify AI-written code.
+- **PHPDoc mixed rule relaxed** - Nullable JSON bags such as `array<string, mixed>|null` no longer trigger `phpdoc-mixed-overuse`.
+- **Internal cleanup** - Large command and analysis classes were split up. CLI behaviour and output schemas are unchanged.
+- **`docs.return-comment` changed meaning** - Same rule id, new behaviour: value-returning `@return` tags need a real description. Baselines may shift.
+- **`docs.missing-param-tag` covers more methods** - Documented private/protected methods and functions now need `@param` tags. Baseline old gaps if needed.
 
 ## 0.2.0 - 2026-05-28
 
-gruff-php 0.2.0 tightens the CI gating philosophy, requires explicit config-schema versioning, and adds a per-rule triage surface so large scans stop being overwhelming. Five breaking changes (`schemaVersion:` required, `analyse` default lowered, JSON schemas v2, one rule retired, `waste.one-line-method` defaults tightened) motivate the minor bump from 0.1.x; each ships with a migration path below.
-
-- **BREAKING: `schemaVersion:` required in `.gruff-php.yaml`** - Every config must declare `schemaVersion: gruff-php.config.v0.1` at the top, or `gruff-php analyse` and friends refuse to load with `Config key "schemaVersion" is required. Add 'schemaVersion: gruff-php.config.v0.1' to the top of .gruff-php.yaml, or regenerate with 'gruff-php init --force'.` Migration: add the line by hand, or run `gruff-php init --force` (preserves your existing `paths.ignore`, rule tunings, and `allowlists`). Rationale and pre-public-adoption window in [ADR-015](.goat-flow/decisions/ADR-015-per-command-minimum-severity.md).
-- **BREAKING: `analyse --fail-on` default lowered from `error` to `advisory`** - CI jobs that previously exited 0 on advisory- or warning-tier findings now exit 1 by default. Matches the cross-port "show everything, fail on anything for gating commands" philosophy. Migration: pass `--fail-on error` on every CI invocation, or pin `minimumSeverity.analyse: error` in `.gruff-php.yaml` to restore the prior gate. To opt into the new default explicitly, pin `minimumSeverity.analyse: advisory`.
-- **BREAKING: `summary` and `analyse` JSON schemas bumped to v2** - `summary` is now `gruff.summary.v2`, `analyse` is now `gruff.analysis.v2`. Per-severity counts in `findings`, `pillars`, and `topOffenders` payloads switch from plural (`advisories` / `warnings` / `errors`) to singular (`advisory` / `warning` / `error`). Migration: update consumer parsers for both the schemaVersion literal and the key renames. No backward-compatible aliases ship; v1 consumers must update.
-- **BREAKING: `naming.parameter-type-name` retired** - Rule class, fixture, `RuleRegistry::NAMING_RULE_PRIORITY` slot, `docs/rules.md` row, and dogfood tuning block deleted. Adopters with a `rules.naming.parameter-type-name` block in their config hit `Unknown rule id "naming.parameter-type-name".` at load time. Migration: delete the block from `.gruff-php.yaml`; findings disappear from baselines and reports automatically. The gruff-py port retires the sibling in lockstep (their ADR-018). PHP naming rules drop 12 to 11. Rationale in [ADR-014](.goat-flow/decisions/ADR-014-retire-naming-parameter-type-name.md).
-- **BREAKING: `waste.one-line-method` defaults tightened** - `minInFileCallers: 0 → 2`, `namedAlternativeFactoryExempt: false → true` (matches gruff-php's own self-tuning). Most projects see *fewer* findings: named factory pairs like `Money::fromCents()` / `Money::fromDollars()` and same-file wrappers stop reporting. Migration: no action required for adopters relying on defaults. To preserve the prior loose defaults explicitly, pin `options.minInFileCallers: 0` and `options.namedAlternativeFactoryExempt: false` under `rules.waste.one-line-method`.
-- **Per-command exit-code thresholds** - New `minimumSeverity:` block in `.gruff-php.yaml` pins CI policy per command (`analyse | report | dashboard`) once instead of remembering `--fail-on` on every invocation. Accepted values: `advisory | warning | error | none`. Non-gating keys (`summary`, `init`, `list-rules`) and non-canonical values (including gruff-go's `never`) are rejected with explicit errors. Precedence: explicit CLI `--fail-on` > YAML > binary default. `AnalysisConfig::failThresholdFor()`, `ConfigLoader::SCHEMA_VERSION`, and `ConfigLoader::GATING_COMMANDS` are the new accessor / constants.
-- **Visibility-only rule tier (`excludeFromScore`)** - `rules.<id>.excludeFromScore: true` keeps a rule running and surfaces its findings in every report, but those findings stop penalising the composite/pillar score. Distinct from `enabled: false` (which silences the rule entirely). Composite findings honour the flag transitively via `metadata.componentRules`. Useful when a team has decided a rule is informational but still wants to see what it catches. Design and failure-mode comparison in [ADR-016](.goat-flow/decisions/ADR-016-visibility-only-rule-scoring-tier.md).
-- **Per-rule triage surface for large scans** - `list-rules <ruleId>` renders default options, escape-hatch config paths (`rules.<id>.options.*`, `enabled`, `excludeFromScore`), and catalogued false-positive shapes for the named rule; typos suggest near matches via Levenshtein and exit 2. `analyse --format=text` adds a footer hint pointing at `gruff-php summary` when findings ≥ 50. Branch-review reporters (`TextReporter` + `MarkdownReporter`) render "Top 5 improved / Top 5 regressed" rules before the composite score; `BranchReviewResult::perRuleDelta()` is the JSON-exposed source. `AnalysisReport::findingCountsByRule()` is the new accessor for triage views.
-- **Line-shift-resilient finding identity** - `Finding::stableIdentity` is a 16-character SHA-256 sibling to `fingerprint`, keyed by `[ruleId, file, symbol]` (or `[ruleId, file, message]` when symbol is null). Line-insensitive so external diff tooling can track "the same finding" across unrelated edits. Baselines and SARIF stay keyed on `fingerprint`; the new field is additive metadata in JSON output.
-- **Precise `array{...}` envelope exemption** - `modernisation.phpdoc-mixed-overuse` no longer fires on shapes like `array{entries: list<array<string, mixed>>, total: int|null, complete: bool}` when at least one named sibling field has a non-mixed type. Loose shapes still fire: `array<string|int, mixed>`, `Collection<mixed>`, `array{value: mixed}`.
-- **Cleaner first-run experience** - `init` now scaffolds default accepted abbreviations for `naming.abbreviation-allowlist` (`id`, `url`, `db`, etc.) so fresh `.gruff-php.yaml` files no longer flood with universal tokens. HTML and Markdown reporters render per-pillar summaries as a table with per-severity columns instead of single-count rows. 11 rule remediations now name their escape-hatch config path ("If this is intentional, add it to `rules.<id>.options.<key>` in `.gruff-php.yaml`") so users can act on a finding without grepping for the right knob.
-- **Config and CLI wiring fixes** - `ReportCommand::resolveFailOn()` now correctly detects whether `--fail-on` was passed explicitly (via `hasParameterOption`) instead of treating the option's `'none'` default as explicit; `minimumSeverity.report` actually takes effect now. `DashboardStateFactory::loadConfigFailThreshold()` reads `.gruff-php.yaml` from the resolved `--project-root` instead of `getcwd()`. `AnalysisConfig` no longer clobbers universal `acceptedAbbreviations` defaults when a user's `allowlists:` block declares only `secretPreviews`. `MissingParamTagRule` no longer treats `@param-out` or `@param-immutable` as `@param` matches (word-boundary check prevents PHPStan/Psalm out-only tags from suppressing missing-input-param findings).
-- **Regression coverage for the new contracts** - `tests/Reporting/FailThresholdTest.php` locks the `FailThreshold::fromInput` parser contract; `tests/Console/AnalyseMinimumSeverityPrecedenceTest.php` covers the precedence chain end-to-end; `tests/Analysis/AnalysisReportTest.php`, `tests/Reporting/TextReporterTest.php`, and `tests/Review/BranchReviewResultTest.php` cover the new accessors and volume-hint behaviour.
+0.2.0 makes CI policy more explicit, adds rule triage help, and introduces several breaking config/schema changes.
+
+- **BREAKING: `schemaVersion:` is required** - Add `schemaVersion: gruff-php.config.v0.1` to `.gruff-php.yaml`, or run `gruff-php init --force`.
+- **BREAKING: `analyse --fail-on` default changed** - `analyse` now fails on advisory findings by default. Pass `--fail-on error` or set `minimumSeverity.analyse: error` to keep the old gate.
+- **BREAKING: JSON schemas moved to v2** - `summary` and `analyse` now emit v2 schemas and singular severity count keys. Update JSON consumers.
+- **BREAKING: Removed `naming.parameter-type-name`** - Delete any config for this rule. Findings disappear automatically.
+- **BREAKING: `waste.one-line-method` defaults tightened** - Most projects see fewer findings. Pin the old options only if you need the old behaviour.
+- **Per-command severity config** - `minimumSeverity:` lets config set fail thresholds for `analyse`, `report`, and `dashboard`.
+- **Visibility-only rules** - `excludeFromScore: true` keeps a rule visible in reports without affecting scores.
+- **Rule triage help** - `list-rules <ruleId>` now shows options, escape hatches, and false-positive notes. Large text reports point users toward `summary`.
+- **Stable finding identity** - JSON adds a line-shift-resistant `stableIdentity` field for external diff tooling.
+- **Fewer mixed-type false positives** - Precise `array{...}` PHPDoc shapes with useful sibling fields no longer trip `phpdoc-mixed-overuse`.
+- **Cleaner first run** - `init` now seeds common abbreviations, reports are easier to scan, and rule messages point at config escape hatches.
+- **Bug fixes** - Fixed report/dashboard fail-threshold loading, abbreviation defaults, and `@param-out` / `@param-immutable` handling.
+- **Regression tests** - Added coverage for fail-threshold parsing, precedence, report hints, and new accessors.
 
 ## 0.1.3 - 2026-05-24
 
-Patch release for the installed Composer binary bootstrap.
+Patch release for Composer installs.
 
-- **`vendor/bin/gruff-php` works in consuming projects** - The installed binary now prefers Composer's generated `_composer_autoload_path` before source-checkout fallbacks. Unblocks `composer require --dev blundergoat/gruff-php` followed by `vendor/bin/gruff-php init`, which previously failed at the autoload lookup.
-- **Regression test for the packaged dependency layout** - New test installs `gruff-php` into a throwaway consumer project and runs `vendor/bin/gruff-php init`, so the packaged path is covered separately from `php bin/gruff-php` source-checkout runs.
+- **Installed binary fixed** - `vendor/bin/gruff-php` now finds Composer's generated autoload path in consuming projects.
+- **Packaging regression test** - Tests now cover installing and running `vendor/bin/gruff-php init` from a throwaway project.
 
 ## 0.1.2 - 2026-05-24
 
 Harness and documentation maintenance for goat-flow 1.7.0.
 
-- **Updated instruction files for the goat-flow 1.7.0 audit CLI** - Codex and Claude instructions now use the packaged `@blundergoat/goat-flow` audit CLI and list the real app/quality surface (`.gruff-php.yaml`, `phpstan.neon.dist`, scripts, `package-lock.json`, GitHub workflows).
-- **Consolidated goat-security reference stubs** - Legacy Claude `goat-security` reference files now redirect to `identity-and-data.md` and `supply-chain-and-cicd.md`, preventing stale guidance from loading accidentally.
-- **Refreshed architecture and code-map docs** - Coverage for the current CLI surface (the `init` command, dedicated Console test files, `skill-playbooks` routing, and resolved CLI footguns around config creation).
-- **Hook self-tests use real fixtures** - `dangerous-command` hook self-tests now use the real `healthkit/healthkit` repository identifier instead of `example-org/example-repo` placeholders.
-- **Broadened symfony/yaml constraint** - Runtime constraint now matches the other Symfony components: `^6.4 || ^7.0 || ^8.0`.
+- **Agent instructions updated** - Codex and Claude docs now use the packaged goat-flow audit CLI and list the real project quality surface.
+- **Security references cleaned up** - Old goat-security stubs now redirect to the current identity/data and supply-chain/CICD references.
+- **Architecture docs refreshed** - Code map and architecture docs now cover the current CLI and local workflow.
+- **Hook fixtures fixed** - Dangerous-command hook tests now use the real fixture repository name.
+- **Symfony YAML range widened** - Runtime support now matches the other Symfony components: `^6.4 || ^7.0 || ^8.0`.
 
 ## 0.1.1 - 2026-05-24
 
 Onboarding-focused follow-up to 0.1.0.
 
-- **`init` scaffolds `.gruff-php.yaml` from registry defaults** - New `gruff-php init` command writes a config with registry defaults plus a curated `paths.ignore` list (agent harness dirs, generated reports, fixtures, vendored copies). `--force` regeneration preserves any existing `paths.ignore`; `init` refuses to silently shadow a legacy `.gruff.yaml` without `--force`. `--project-root <dir>` writes into a directory other than the current shell.
-- **Interactive missing-config prompt** - When `analyse`, `summary`, `report`, or `dashboard` runs in a TTY against a project without `.gruff-php.yaml` or `.gruff.yaml`, the command offers to run `init`. The prompt fires only after option validation so malformed invocations no longer leave a stray config file behind, and prompt chatter routes to STDERR so JSON, SARIF, and HTML payloads on STDOUT stay parseable.
-- **Test-quality rules enabled by default** - `test-quality.multiple-aaa-cycles` (minCycles 3), `test-quality.mocking-domain-object`, and `test-quality.testdox-readability` (minWords 2) now run unless explicitly disabled. Existing projects see new advisory findings on these rules after upgrade; configure or disable per project as needed.
-- **Baseline guidance in `summary` output** - Text output now points users at `analyse --generate-baseline` to record current findings as known debt, and `--no-baseline` to audit without one.
-- **Composer dependency audit in `composer check` and CI** - `composer audit:dependencies` runs inside `composer check` and the CI verify job, failing the build on known security advisories in the lockfile. `scripts/dependency-install.sh` and `dependency-update.sh` wrap the Composer commands used during installs and refreshes; the release preflight script is stricter.
-- **README and `docs/` rewrite** - New documentation covers rule catalogue (`docs/rules.md`), CI integration (`docs/ci-integration.md`), configuration reference (`docs/configuration.md`), output formats (`docs/output-formats.md`), dashboard usage (`docs/dashboard.md`), naming conventions (`docs/naming-conventions.md`), and the release process (`docs/releasing.md`).
+- **`init` command added** - `gruff-php init` creates `.gruff-php.yaml`, preserves ignore patterns with `--force`, and supports `--project-root`.
+- **Missing-config prompt** - TTY runs can offer to create config before scanning.
+- **More test-quality rules enabled** - New default advisory rules catch common weak-test patterns.
+- **Baseline guidance added** - `summary` now points users to baseline generation and no-baseline audit modes.
+- **Dependency audit added** - Composer audit now runs in `composer check` and CI.
+- **Docs expanded** - README and docs now cover rules, CI, config, output formats, dashboard, naming, and release process.
 
 ## 0.1.0 - 2026-05-23
 
 First public release.
 
-- **120 rules across 11 pillars** - Coverage spans size, complexity, maintainability, dead-code, naming, documentation, modernisation, security, sensitive-data, test-quality, and design. Run `php bin/gruff-php list-rules` to inspect the catalogue.
-- **Five commands** - `analyse`, `summary`, `report`, `dashboard`, `list-rules`. Each carries `--help` for option discovery.
-- **Seven output formats with stable schemas** - `text`, `json`, `html`, `markdown`, `github`, `hotspot`, `sarif`. Initial machine-readable schemas: `gruff.analysis.v1`, `gruff.summary.v1`, `gruff.baseline.v1`.
-- **YAML config with strict unknown-key rejection** - `.gruff-php.yaml` supports baselines, branch-review (`--diff`, `--diff-vs`, `--changed-only`), opt-in Infection mutation analysis, and a local dashboard. Unknown top-level keys fail to load.
-- **PHP `^8.3`, MIT licensed** - Minimum runtime is PHP 8.3.0; the project is MIT-licensed.
