From 5e46c7dc77b402010aa6bbf7500c12216c83c335 Mon Sep 17 00:00:00 2001 From: Matt Miller Date: Mon, 27 Jul 2026 14:22:32 -0700 Subject: [PATCH 1/4] feat(groom): `path` input scopes an audit to one directory, without resetting the cadence clock (BE-4757) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds `path` (string, default '') to groom.yml so a run — typically a manual dispatch, but any caller may pin one — audits ONE directory instead of the whole repo. Empty reproduces today's behavior, so all existing callers are unaffected. Enforced, not merely instructed (scope_label/scope_desc were prompt prose only): syntactic validation in the cheap gate job, filesystem containment against the checkout in the finder job, a concrete in-scope file list handed to the finder, and a post-filter that drops findings whose evidence lies entirely outside the scope with the dropped count logged. The checkout stays FULL on purpose. Critically, a scoped run must not stamp "done" over the whole-repo audit it never performed: workflow_dispatch bypasses the interval gate, so a scoped run reaches the finder. The finder job is renamed `Audit — finder (scoped)` and interval.py excludes that marker when deriving the last real groom, so the next scheduled whole-repo tick stays DUE. The dedup signature is likewise decoupled from `path` (verifier.md's new `{{SIG_SCOPE}}` is wired to the caller's RAW scope_label), so a scoped run and a whole-repo run suppress each other's duplicates. --- .github/groom/interval.py | 30 +- .github/groom/scope.py | 397 +++++++++++++++++++++++ .github/groom/tests/test_interval.py | 54 +++ .github/groom/tests/test_scope.py | 387 ++++++++++++++++++++++ .github/groom/verifier.md | 2 +- .github/workflows/groom.yml | 202 +++++++++++- .github/workflows/test-groom-scripts.yml | 19 +- AGENTS.md | 5 +- README.md | 2 +- 9 files changed, 1080 insertions(+), 18 deletions(-) create mode 100644 .github/groom/scope.py create mode 100644 .github/groom/tests/test_scope.py diff --git a/.github/groom/interval.py b/.github/groom/interval.py index e162c54..003ea25 100644 --- a/.github/groom/interval.py +++ b/.github/groom/interval.py @@ -21,6 +21,9 @@ finder (its `Audit — finder` job ran, i.e. was not `skipped` by this very gate), so the interval-skip ticks in between never reset the clock.

It CONSTRAINS rather than instructs (unlike `scope_desc`, which is prompt prose): the path is validated (absolute / `..`-component / escaping paths rejected) and contained against the checkout before any agent runs, the finder is handed the concrete in-scope file list, and findings whose evidence lies entirely outside the directory are dropped with the count logged. The checkout stays **full** on purpose — a refactor in `services/api` legitimately references `common/`. A scoped run does **not** reset the cadence clock (its finder job is renamed `Audit — finder (scoped)`, which the interval gate excludes), so the next scheduled whole-repo tick stays due; and the dedup signature ignores `path`, so a scoped run and a whole-repo run suppress each other's duplicates.

The finder job marker carries the path (`(scoped: services/api)`), and a tick counts only a prior run of its own scope. A scope-blind `(scoped)` exclusion left a permanently path-scoped caller — a configuration the `path` input explicitly advertises — with no countable run in history, failing open on every tick and re-billing the audit daily regardless of GROOM_INTERVAL_DAYS. - interval.py: a job matched only by the bare `audit_find` id form carries no rendered display name, and therefore no scope marker, so it can no longer be attributed to a whole-repo run. Unknown scope now falls through to fail-open rather than letting a scoped run suppress the next full sweep. - scope.py: `normalize_site` collapses traversal and rejects a site that climbs out of the repo root, so `services/api/../../common/x` can no longer pass the lexical prefix test — the `..` hole `validate_path` already closes on the input side, closed on the side the agent controls. - scope.py: `scope_note` now states the ANY-in-scope rule the filter actually enforces. Demanding EVERY site be in scope told the agents to suppress the cross-boundary findings the full checkout exists to enable. - scope.py: the filter FAILS when the finder emitted no `findings` array. The workflow's only check is `jq '.findings | length'`, which scores a missing field as 0 — indistinguishable from a clean directory, so a structurally broken finder went green on nothing. - scope.py: `derive_scope` exposes `sig_scope`, the normalized (never path-derived) dedup-signature scope, wired to verifier.md's {{SIG_SCOPE}}. A blank `scope_label` previously reached the brief empty and yielded `repo::slug`. - scope.py: tracked filenames with control characters are dropped rather than inlined into the finder prompt, where a newline could forge file-list entries. - groom.yml: a scoped run with zero tracked files now fails loudly instead of buying a billed audit that can only report "clean" (an all-gitignored directory passes containment). - scope.py/groom.yml: drop the private consumer repo/directory tuple from this public repo, per AGENTS.md.

A finding with no LOCATABLE site is KEPT there (the opposite of the finder-side rule): `sites` is advisory on that schema, so dropping on it would discard every survivor and read as an honest "nothing survived verification". - `canonicalize_signature` forces the dedup key's scope component back to the literal the brief handed out, so signature scope-independence no longer rests on an untrusted model obeying `{{SIG_SCOPE}}`. Left alone when `scope_label` itself contains a colon — component boundaries are ambiguous there, and corrupting a working dedup key is worse than the double-filing it guards. - `normalize_site` no longer relativizes an absolute path that is NOT under the clone; it returns "" (unlocatable). Stripping the leading slash silently reinterpreted `/services/api/x.go` as repo-relative, so an out-of-tree site could satisfy a matching scope. - `resolve_within` rejects a SYMLINKED scope even when it points inside the repo.

Five fixes, one deferral. * SUBMODULE SCOPE READ AS CLEAN. `git ls-files -- ` on a submodule returns the mode-160000 gitlink as a single entry, so `list_files` was non-empty, groom.yml's empty-list guard passed, and the finder audited a directory a default checkout never populates — reporting it clean. The listing is now taken with `-s` and gitlinks are skipped (and warned about), so a submodule-only scope falls through to the empty-list FAILURE instead. Verified the premise: groom.yml never passes `submodules:` to actions/checkout, so a submodule's files are genuinely unauditable here; the error names the working path (groom it from its own repository). * UNICODE LINE SEPARATORS FORGED PROMPT LINES. `printable_path` rejected ASCII controls but not U+0085/U+2028/U+2029, which Git permits in filenames and many consumers render as a line break — so a planted name could still forge `- {f}` bullets in the finder's authoritative file list. * FILE LIST CAPPED BY COUNT, NOT SIZE. 1500 deeply-nested near-PATH_MAX names cleared `_MAX_LISTED_FILES` and still serialized to megabytes, overflowing the finder's context. Now capped by bytes as well, always listing at least one name so a single pathological path cannot empty the block. * A VERDICT TYPO WAS SILENTLY DISCARDED. groom.yml's malformed-finding check required `verdict` to be a string but not one of CONFIRM/DOWNGRADE/REJECT, so `CONFIRMED` passed validation and was then dropped by the KEEP filter — a real confirmed finding lost with the run green, the exact silent discard that fail-loud step exists to prevent. * AN OVER-LONG PATH KILLED THE CADENCE CLOCK. The path is embedded in the finder job name as the `(scoped: )` marker `interval.py` matches; GitHub truncates a long job name, so no prior run is ever recognised and a permanently scoped caller re-bills its audit every tick. `validate_path` now caps the normalized path at 160 characters. Not fixed, deliberately: `site_in_scope` stays purely lexical (replied on the thread), and counting a PRE-AGENT finder failure as a spent audit is deferred to a follow-up — it lives in `_AUDITED_CONCLUSIONS`, predates path scoping, and changing it alters cadence for every groom run, whole-repo included. Tests: submodule gitlink, the three line separators, the byte cap and its always-list-one floor, and the path-length cap (including that it is measured after normalization). 165 -> 170 green. --- .github/groom/scope.py | 104 +++++++++++++++++++++++++++--- .github/groom/tests/test_scope.py | 69 ++++++++++++++++++++ .github/workflows/groom.yml | 26 ++++++-- 3 files changed, 183 insertions(+), 16 deletions(-) diff --git a/.github/groom/scope.py b/.github/groom/scope.py index a7b9a94..dd153d8 100644 --- a/.github/groom/scope.py +++ b/.github/groom/scope.py @@ -91,11 +91,33 @@ # for `file:line`, so the location suffix is stripped before the containment test. _SITE_LOCATION_RE = re.compile(r":\d+(?:[:-]\d+)?$") -# How many in-scope files to inline in the finder prompt.
