From f921562828ec3fd11b554630c7d826800f2571df Mon Sep 17 00:00:00 2001 From: John Morrissey <544926+tachyon-beep@users.noreply.github.com> Date: Mon, 8 Jun 2026 01:32:20 +1000 Subject: [PATCH 01/22] feat(governance): honest unconfigured-governance seams (N3/N4) + C3 doc; C-8 preserved MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Dogfood-#2 governance honesty (convention C-10), branch-local — merge/release gated on the filigree-first propagation. Capability confinement (proposed C-8) preserved throughout: operator signing keys stay out of agent reach, nothing is auto-provisioned/relocated, no MCP tool enables a cell or self-grants authority. N3 (weft-df8d2ef454, C-10(c)) — legis no longer ships dark and quiet: - mcp.py _recovery_for: INVALID_CELL_SPEC names LEGIS_WARDLINE_CELL / LEGIS_WARDLINE_CELL_BY_SEVERITY (covers all WardlineRoutingError kinds, incl. those str(exc) misses); CELL_NOT_ENABLED split into the keyless simple tier (policy/cells.toml / LEGIS_POLICY_CELLS / LEGIS_DEV_DEFAULT_CELLS) and the complex tier (LEGIS_HMAC_KEY, operator out-of-band + relaunch). Subsumes Le1. - doctor.py: two report-only checks (check_policy_cells, check_wardline_routing) naming the enablement path when unwired — presence-only, no repair param, write nothing, never render a key value. Fail-closed preserved (no auto-open). N4 (weft-a7a92a40dd, C-10(d)) — honest dirty-tree skip: - WardlineDirtyTreeError.to_payload() is the single source both transports (mcp.py scan_route + api/app.py) serialize: structured reason/posture/cause/ remediation, routed==[] (governs nothing). No scan_route call argument added; the LEGIS_WARDLINE_ALLOW_DIRTY dirty-snapshot opt-in stays an env-only operator switch. C3 (weft-f506e5f845) — charter now documents that legis's OWN audit records carry a self-asserted agent_id/operator_id (launch-bound + HMAC-tamper-evident, not authenticated); verified_author:null maps to those fields. Guards: test_c8_no_agent_reachable_enablement_or_signing_surface (no enable/sign tool; scan_route schema locked) + doctor checks write-nothing/render-no-key test. 762 passed; ruff + mypy clean; coverage 92.30%; per-package floors hold; policy-boundary-check PASS; SEI oracle PASS. Designed + adversarially red-teamed (C-8 verdict: safe) and implementation-reviewed via multi-agent workflows.

Values unchanged (active/waived/suppressed/baselined/judged); the `Suppressed` enum (value vocabulary) and SUPPRESSION_PROOF_KEYS are untouched. - clean break: a finding carrying only the legacy `suppressed` key reads as `active` and OVER-gates — fail-safe (never silently drops a real defect), pinned by test_legacy_suppressed_key_is_ignored_clean_break. - NO signing/canonical change: legis's signer already reproduces Wardline's rekeyed golden byte-for-byte. Added the legis-side cross-impl golden MIRROR legis was missing: sign(_GOLDEN_FIELDS, _GOLDEN_KEY) == hmac-sha256:v2:2b2cf09… over `suppression_state`, so the hop self-verifies on both ends. - intake fixtures: ~40 `suppressed` test fixtures across tests/wardline, tests/api, tests/mcp, tests/store renamed to `suppression_state` (a sweep flagged these to avoid vacuously-green suppression-path assertions). Acceptance: legis 767 tests green; golden byte-agreement pinned; the live signed hop verifies — wardline's `-m legis_e2e` test_legis_accepts_signed_artifact PASSES against the reinstalled legis (real build_legis_artifact -> signed suppression_state artifact -> legis verifies + routes). Branch-only; ship via the filigree-gated rc4->main merge.

The fingerprint is blind to decorators (Q-L5 parity), so the drift check is byte-identical and cannot see the disablement. Add a highest-priority disabled-evidence judgement in the shared evaluate_test_evidence so both the runtime gate and the static boundary scanner reject it identically (new POLICY_BOUNDARY_TEST_DISABLED). Marker match is terminal-name based, so it catches the import-alias form (`from pytest import mark; @mark.skip`) whose only tell lives outside the function source the fingerprint sees. N1 — add report-only check_filigree_binding_scope to doctor: an unscoped federation-write binding in .mcp.json (/api/weft/… etc.) is fail-closed with HTTP 400 by a filigree server-mode daemon, so scans silently non-emit.

Both are confirmed fail-closed *honesty breaks* — a governance gate reports green on exactly the condition it exists to catch. Neither is a systemic flaw; the rest of the suite (9 lanes, 767 tests green, 92% coverage) is sound and fail-closed where it counts. No NO-GO. + +### The two decision-driving questions + +**Does 1.0 cross the cryptographic-guarantees threshold? NO.** The crypto lane enumerated every verifier of a legis-produced `canonical_json` HMAC — all are same-process Python (TrailVerifier, binding_ledger, the protected-cell verify). The only cross-process verify (`verify_wardline_artifact`) checks Wardline's *inbound* signature against a deliberate byte-for-byte Python replica, not a legis attestation, and not cross-language. The legis→Filigree `attach(signature=...)` is an app-level string Filigree merely records; the transport X-Weft HMAC only proves *who* is calling. So no non-Python consumer cryptographically verifies a legis attestation. The protected-cell HMAC is exactly what the docstring claims: intra-suite tamper-evidence against a DB-file-holder, not a third-party cryptographic guarantee. Therefore the settled deferrals (ensure_ascii, v1-canonical, unsigned-channel fallback, dirty-tree) stay post-1.0 and fail *visibly*. The tripwire is named and one-file-sized: the day a non-Python verifier of a legis attestation lands, the v1-canonical deferral becomes a blocker. + +**Judge-injection result: fail-closed.** The prime fail-open hypothesis — LLM error/timeout/unparseable response → ACCEPTED — is DISPROVEN: every transport/shape failure raises `LLMTransportError`, propagates with no record written, and surfaces as INTERNAL_ERROR, never ACCEPTED. Structural prompt injection (forging a sibling `{"verdict":"ACCEPTED"}` key) is closed because the agent rationale is JSON-escaped into a string value. The only residual is the coached cell, where a *semantic* injection that fools the judge model clears the gate with no defense-in-depth — that is a model-robustness property, not a code fail-open, and is post-1.0 (JUDGE-1). + +### The 2 blockers + +1. **POLICY-1 (policy-engine, high)** — `decorator.py:121` blanket-strips `decorator_list` before fingerprinting a `@policy_boundary`'s evidence test. Adding `@pytest.mark.skip`/`@xfail` after a human pins the test yields a byte-identical fingerprint, so the CI `policy-boundary-check` stays green while the proof test no longer runs. Reproduced end-to-end. The decorator strip is the load-bearing Q-L5 parity contract and must NOT be reverted; the fix is additive — emit a `POLICY_BOUNDARY_TEST_DISABLED` finding when the evidence test carries a skip/xfail marker. This is the canonical agent-first disable-after-pin path. + +2. **GOV-1 (governance-honesty, high)** — `app.py:742` computes the `/governance/lineage-integrity` headline as `"unverified" if integrity.unavailable else "verified"`, ignoring `integrity.divergences`. A confirmed external-Loomweave lineage tamper (empty `unavailable`, populated `divergences`) is reported `status="verified"`. Self-incriminating: the *lesser* can't-fetch failure already maps to "unverified", so reporting the *greater* confirmed-tamper as "verified" is internally incoherent. One-line fix: treat any divergence as not-"verified" (emit "diverged"). + +Both fixes are small (one additive rule; one boolean), localized, and each needs one test that pins the headline/finding on the tamper case (the existing tests assert the *data* is present but pointedly skip the *status*/marker assertion). + +### Top tracked follow-ups (non-blocking) +- **AUD-1 (high, post-1.0):** out-of-band DB-file delete-and-rechain is undetectable because `signing_fields` binds content but not position; real, but outside the stated forgery guarantee and needs the conceded file-write capability.

AUD-2 refuted (seq reuse breaks the signed content_hash, not silent). 0 blockers. +- **policy-engine** — NO-GO until POLICY-1 fixed — @policy_boundary fingerprint is blind to @skip/@xfail, a confirmed agent-first false-green honesty break on the CI-enforced gate. 1 blocker. +- **mcp-surface** — GO — C-8 key-confinement holds; MCP-1 (protected-cell vs protected_policies config split) verifier-downgraded to a non-blocker operator-misconfig footgun (no agent reach, honest escalation in the human-gate cell). 0 blockers. +- **api-authz** — GO — unconfigured server fail-closed 401 on all writes; AUTH-1 unscoped-token flag is by-design/default-closed/not-agent-reachable. 0 blockers. +- **judge-injection** — GO — prime fail-open (error/timeout/unparseable -> ACCEPTED) DISPROVEN, fail-closed to BLOCKED; structural injection closed by JSON-escaping. Coached-cell semantic injection is a post-1.0 model-robustness note. 0 blockers. +- **governance-honesty** — NO-GO until GOV-1 fixed — /governance/lineage-integrity reports status=verified on a confirmed lineage divergence (keys only on unavailable). 1 blocker. +- **identity-sei** — GO — every SEI degrade path fail-closed to a locator key with identity_stable=False; uncovered lines benign. 0 blockers, 1 low unsigned-probe note. +- **install-doctor** — GO — secret invariant holds (no key/token ever written to a committed file), --repair non-destructive on governance; split-brain/backup-clobber/env-overwrite are post-1.0. 0 blockers. + +## Blockers (must close before 1.0) + +### POLICY-1 — high +- **Location:** src/legis/policy/decorator.py:120-121 (get_normalized_ast_str strips decorator_list); gate teeth in evaluate_test_evidence, reached via decorator.py:206 runtime + boundary_scan.py:159 static +- **Claim:** The @policy_boundary honesty gate blanket-strips ALL decorators before fingerprinting a boundary's evidence test, so adding @pytest.mark.skip / @pytest.mark.xfail to a previously-pinned test produces a byte-identical fingerprint and the CI drift check (legis policy-boundary-check) stays green while the behavioural-evidence test no longer runs. +- **Impact:** Agent-first disable-after-pin: (1) a human approves a real running test for a self-exempting @policy_boundary and the agent pins meta.test_fingerprint; (2) the boundary suppresses named policies ONLY on the strength of that live test; (3) the agent later edits the test to @pytest.mark.skip(...) — it never executes; (4) fingerprint_source is blind to decorator_list so the hash is unchanged, the runtime drift check (decorator.py:206) and static mismatch check (boundary_scan.py:159) both pass; (5) CI reports PASS. The boundary now carries a self-exemption from named policies with zero executing proof and no human re-review, because nothing flagged drift. pyproject has no xfail_strict/strict-markers, so the suite itself does not fail the skip — the policy-boundary-check green is the sole authoritative signal and it is false-green. Reproduced end-to-end: skip-identical and xfail-identical fingerprints both True; evaluate_test_evidence never inspects decorator_list; no skip/xfail rule exists in boundary_scan._EVIDENCE_RULE_IDS. +- **Fix:** Do NOT revert the decorator strip — it is the load-bearing Q-L5 fingerprint-parity contract (inspect.getsource includes decorators, ast.get_source_segment excludes them). Instead, in evaluate_test_evidence (or boundary_scan), scan the evidence test's decorator_list for pytest skip/xfail/skipif markers and emit a new POLICY_BOUNDARY_TEST_DISABLED finding so a disabled evidence test can never satisfy the gate. Add a tests/policy/ case asserting a @pytest.mark.skip-decorated evidence test fails the boundary check. +- **Verifier:** is_real=true, is_blocker=true, severity=high +- **Resolution (2026-06-08, CLOSED):** Fixed additively in the shared evaluator `evidence.evaluate_test_evidence` — the single point both gates route through, so the runtime gate and the static scanner pick up `POLICY_BOUNDARY_TEST_DISABLED` identically and parity holds by construction. Decorator strip untouched (Q-L5 intact). Detection (`_disabling_marker`) is deliberately broad/fail-closed: terminal-name match on `{skip, skipif, xfail}` for any attribute or bare name, with/without a call, so import-aliased forms (`from pytest import mark` → `@mark.skip`) — whose only tell lives outside the fingerprinted function source — are still caught. Tests: `tests/policy/test_evidence.py` (5 evaluator cases incl. skipif + alias + a no-false-positive parametrize guard), `tests/policy/test_boundary_scan.py` (2 end-to-end killer cases pinning the clean fingerprint then disabling on disk — the `len == 1` + `TEST_DISABLED` rule_id simultaneously proves the fingerprint still matched and the new rule fired), `tests/policy/test_honesty_gate.py` (runtime gate, with an explicit assertion that the disabled fingerprint == the clean one). Strict suite green (775 passed, 2 pre-existing conformance skips); `legis policy-boundary-check` PASS over the real tree (zero shipped decoration sites today, so no live boundary regressed). **Residuals (named, NOT fixed — same false-green class, but unfixable here without breaking Q-L5 parity since the runtime gate only sees `getsource` of the test function/method):** module-level `pytestmark = pytest.mark.skip` and a class-level `@pytest.mark.skip` on the test's enclosing class. Both are documented in the `_disabling_marker` docstring. A future hardening that wants them must add an out-of-band whole-file/class scan on the static side and accept the runtime/static asymmetry, or move evidence-liveness to an execution-time signal. + +### GOV-1 — high +- **Location:** src/legis/api/app.py:742 +- **Claim:** The /governance/lineage-integrity endpoint computes top-level status as `"unverified" if integrity.unavailable else "verified"`, so a confirmed lineage-prefix divergence (external Loomweave tamper) with an empty `unavailable` list is reported as status="verified". +- **Impact:** An external Loomweave prior event for a protected/SEI-keyed governance record is removed or mutated -> the recorded prefix no longer hashes -> find_lineage_integrity yields divergences=[...], unavailable=[] -> the endpoint returns status="verified". A human-on-the-loop or dashboard alerting on the summary status field sees green while a confirmed lineage tamper sits unread in the divergences array. Internally inconsistent and self-incriminating: the LESSER failure (can't-fetch -> unavailable) maps to "unverified" (test_sei_api.py:170), while the GREATER failure (confirmed tamper) maps to "verified" — no coherent definition of verified makes can't-check not-green but tamper-confirmed green. This is independent of the HTTP-500 audit-store tamper guard (app.py:722), which only covers legis's own HMAC store, not the external entity lineage. Reproduced three ways including direct in-process repro of a length-2 snapshot read back truncated to length-1. +- **Fix:** Make status fail-closed on divergence: status = "verified" only when not integrity.unavailable AND not integrity.divergences; emit "diverged" when integrity.divergences (else "unverified"). Add a status assertion to test_complex_api.py:296, which currently asserts the populated divergences but pointedly omits any status check. +- **Verifier:** is_real=true, is_blocker=true, severity=high + +## Tracked follow-ups (post-1.0, non-blocking) + +### AUD-1 — high (post-1.0) +- **Location:** src/legis/enforcement/protected.py:50-65 (signing_fields) + src/legis/store/audit_store.py:95-96 (_chain) +- **Claim:** The keyed HMAC and the keyless hash chain both bind a record's content but NEVER its chain position or predecessor, so a holder of write access to .weft/legis/gov.db can drop the SQL triggers, DELETE a damning governance record, and re-chain the survivors with verify_integrity()==True and TrailVerifier.verify() passing. +- **Impact:** A file-write actor can silently prune OVERRIDDEN_BY_OPERATOR / BLOCKED records; the override-rate gate (service/governance.py:119) then reads a truncated trail and computes a lower rate. Reproduced empirically. Verifier downgraded to NON-blocker: deletion forges nothing (it removes a validly-signed true record), so it is outside the signing.py docstring's stated forgery guarantee (lines 4-6) and the audit_store hash-chain scope (edit/reorder, not truncation) — a documented gap-in-coverage, not a lie; and it requires the out-of-band raw-SQLite capability already conceded by the C3 file-write threat tier, with no agent-reachable DELETE surface. +- **Follow-up:** Post-1.0: bind seq (and ideally prev chain_hash) into signing_fields and bump the signature tag to v3; persist the head (seq, chain_hash) as an out-of-band anchor and assert monotonic non-rewind on open; add a deletion/truncation test to tests/enforcement/test_trail_verify.py. + +### CRYPTO-THRESHOLD-001 — low (post-1.0) +- **Location:** README.md:7-9,54 vs src/legis/provenance.py:26-27 + CHANGELOG C3 +- **Claim:** README advertises SEI-keyed/governance attestations as Live at an altitude a consumer can read as authenticated cross-party cryptographic proof, while the actor is self-asserted (Provenance.UNAUTHENTICATED) and the signing is intra-suite Python-only HMAC tamper-evidence over v1 canonical JSON. +- **Impact:** No exploit (gates fail closed, unsigned path downgrades visibly); the advertised altitude merely exceeds the enforced guarantee.

Two complementary, isolated mechanisms now close it: * seq-binding (v3) + contiguity — interior delete and reorder. verify_integrity gains an expected-seq counter (a re-chained gap is now a tamper), and protected + sign-off verdicts sign at v3, folding the chain seq into the HMAC. A renumber-to-hide-a-deletion then fails to verify at the new position. seq is taken from the column at verify time, never a payload field. Resolved the sign-before-seq ordering with a store-mediated append_signed: the store reserves seq + prev_hash under its BEGIN IMMEDIATE lock and hands them to a signer callback, so the bound seq is provably the row's seq with no race. The store stays key-agnostic (the callback closes over the gate's key). * HeadAnchor (opt-in) — tail-truncation, the one thing seq-binding structurally cannot catch (a truncated head is legitimately last). A small HMAC-signed sidecar remembers the last (seq, chain_hash); a missing anchor on an anchored store fails closed. Wired as optional gate/verifier params, off by default — conceded-capability hardening that does not touch the 1.0 core. The shared sign()/verify() primitive keeps its v2 default, so the cross-tool Wardline artifact contract and the binding ledger are byte-for-byte untouched. Binding ledger stays v2 (separate, homogeneous store) but is covered by the new contiguity check; renumber-within that store is a documented residual, as is the inherent renumber-vulnerability of an all-unsigned (chill/coached) run. Tests: three attack PoCs, each isolating one mechanism (interior-delete-gap → contiguity; delete-and-renumber → v3 seq-HMAC; tail-truncate → anchor), plus HeadAnchor unit coverage (forged/missing/reappend/no-op) and a v3 signing pin.

It found one genuine residual: the anchor's HMAC stops forgery but not REPLAY. The anchor is a single mutable sidecar, so a snapshotting attacker can save a genuinely-signed early anchor (head=1), let the trail grow, truncate the DB back to seq=1, and restore the saved anchor — it verifies (real signature, consistent seq + chain_hash) and the rollback goes undetected. This is inherent to local same-filesystem storage: nothing on disk is beyond a file-write attacker's rollback, so no purely-local check (counter, timestamp, extra copy) closes it — that would be honesty theatre. The fix is a deployment property: store the anchor on append-only/WORM or remote storage, or run an external monitor on the anchored head's monotonicity. The prior docstring over-claimed it detects "a rollback to an earlier consistent prefix" — false under replay. Corrected to state precisely what it catches (forgery; truncation by a late/non-snapshotting attacker) and the replay limitation + its real mitigation. Pinned the boundary with an executable known-limitation test so the over-claim cannot silently drift back.

The doctor's freshness probe, though, read the token off the FIRST marker only (_MARKER_TOKEN_RE.search → first match) — so a fresh first block masked a stale second block and the doctor reported "healthy" on exactly the conflicting- guidance state it exists to catch. Freshness now requires EXACTLY ONE legis block at the current token, via a new foreign-aware walk (_own_open_marker_tokens) that reuses the injector's own fence-tracking — a legis marker quoted inside a sibling block is not counted, so the probe never miscounts a documented example as a real block. check_instruction _block surfaces a split brain (>1 block) with an actionable hand-resolution message and, since the injector cannot collapse it, does not falsely claim repair fixed it. This is the same honesty discipline as GOV-1/POLICY-1: a gate must not report green on the condition it exists to detect. RED test pinned the false-"ok" first; both CLAUDE.md and AGENTS.md get the fix via the shared check. Full suite 797 passed.

POLICY-2 (this session) — remove the exemption-rescue mechanism outright. PolicyGrammar had a VIOLATION->CLEAR exemption-rescue branch wired to an agent-writable YAML loader (ExemptionAllowlist.from_file) with zero src consumers — the latent bypass trap the finding names. Full removal: delete policy/exemptions.py + tests/policy/test_exemptions.py, drop the exemptions ctor param / _exemptions / rescue branch from grammar.py, and remove the 3 rescue-branch tests. New regression guard test_grammar_has_no_exemption_rescue _mechanism pins that no exemption seam can be re-introduced by accident. This supersedes the earlier conservative document-only closure of legis-e512e97bfc (see ticket history): documenting around the loader left the trap in the tree. AUTH-1 (doc) — app.py comment telegraphs that LEGIS_ALLOW_UNSCOPED_API_TOKENS=1 grants unscoped tokens operator authority (not renamed: the var already fits the LEGIS_ALLOW_ family; audit remedy was "rename OR document"). CRYPTO-THRESHOLD-001 (doc) — README scopes the "cryptographic layer" to intra-suite HMAC tamper-evidence with a self-asserted actor, not third-party cryptographic proof; names RFC-8785 as the upgrade path. Full suite green (792 passed, 2 skipped), ruff clean on changed files.

It is **not** a GOV-1-style documented lie — the gate's own docstring (`protected.py:210-217`) is honest that "Empty set / no validator preserves prior behaviour," and `policy_explain` carries no structured Q-H3 claim. The overclaim is confined to an **internal** construction comment (`mcp.py:186-188`: "a judge ACCEPTED is downgraded" stated unconditionally). What makes it must-fix is the silent absence of protection + no detection + glob-impossibility, not a user-facing false statement. +- **Where:** `enforcement/protected.py:306-310` (downgrade condition) · `:199-200` (defaults `protected_policies=frozenset()`, `validator=None`) · `mcp.py:189-192` & `api/app.py` gate construction (**no `validator=` passed at any site**) · `policy/cells.py:33-40` (glob-capable routing) vs `config.py:168-181` (`protected_policies()`, exact-match only). +- **What's wrong:** Two independent, differently-syntaxed config sources decide (a) *whether a policy reaches the protected gate* — the **cell registry** (`cells.toml`/`LEGIS_POLICY_CELLS`, supports `fnmatch` globs) — and (b) *whether a model ACCEPTED is downgraded inside the gate (Q-H3)* — `protected_policies()` (`LEGIS_PROTECTED_POLICIES`, exact-string, no globs). The downgrade fires only when `policy in self._protected_policies`. A policy routed to `cell="protected"` but **absent** from `protected_policies()` → the judge's ACCEPTED is **not** downgraded, is recorded `accepted=True`, and is **HMAC-signed v3 as authoritative evidence**. Because no call site wires a `validator`, the "non-LLM deterministic validator confirms the ACCEPTED" backstop the audit cites **does not exist at runtime** — Q-H3 reduces entirely to exact set membership. +- **Reachability (verified, normal agent path):** `override_submit` → `cell_for(policy) == "protected"` → `submit_protected_override(...)` (mcp.py:863-888), independent of `protected_policies()`. Two shapes nothing prevents: + 1. **Empty-set default:** `LEGIS_PROTECTED_POLICIES` unset (default `frozenset()`) + any `cell="protected"` route → **every** protected-cell override is fail-open. + 2. **Glob routing:** `pattern="secrets-*", cell="protected"` is expressible in the registry but **cannot** be mirrored in exact-match `protected_policies()`, so Q-H3 can *never* fire for the matched policies — an operator using glob protected-routing has no way to make the protection apply. +- **No detection:** `doctor.py` cross-checks `protected_policies()` against the HMAC key, but never checks protected-cell *routes* against `protected_policies()`. +- **Why it's a fail-open, not model-robustness:** advisory-downgrade-of-the-model's-word is the protected cell's entire reason to exist. Reproduced: a fooled judge returning ACCEPTED yields `accepted=True, verdict=ACCEPTED, signed=True`. +- **Fix direction:** make the protected gate **fail-closed**: if a policy reaches `ProtectedGate.submit()` and there is no effective downgrade path (`validator is None AND policy not in _protected_policies`), do **not** honor a model ACCEPTED — downgrade to BLOCKED/escalate. That makes "routed to protected" *sufficient* for the protection and eliminates the two-config divergence. Minimum: a doctor/startup consistency check that every `cell="protected"` route is covered by `protected_policies()`. + +### GOV-2 — `/governance/identity-gaps` reports the all-clear on the one condition it cannot check **[HIGH/MEDIUM — same class as the GOV-1 blocker]** +- **Where:** `api/app.py:734-739`. +- **What's wrong:** returns bare `[]` when `identity is None or identity.client is None`. An empty list is byte-for-byte indistinguishable from "checked the whole trail, found zero orphan gaps." The endpoint exists to surface orphaned attestations (SEI now `alive:false`); on the exact condition where it cannot do its job (Loomweave unwired) it returns the all-clear. The author already knows the distinction matters — the **sibling endpoint directly below** (`lineage_integrity`, app.py:741-748) returns `status:"unavailable"` for the identical condition (the GOV-1 fix). identity-gaps was simply not given the same treatment. +- **Reachable:** Loomweave unwired (`LOOMWEAVE_API_URL` absent) against a governance DB that already holds SEI-stable attestations from when it *was* wired — normal operation, no special capability. +- **Fix:** return a typed envelope distinguishing "unavailable" from "checked, empty," mirroring lineage-integrity; pin it with a test asserting `status` is not a green reading on the unwired condition. + +### F1 — `protected.py` docstring guarantees a protection the code does not provide (modify-to-unsigned) **[docstring = must-fix honesty; code = post-1.0, conceded tier]** +- **Where:** false claim at `enforcement/protected.py:96-99`; mechanism at `_requires_verification` `:118-127`; same in-record keying in `service/governance.py:152-158`. +- **What's wrong:** the docstring states *"stripping a signature and flipping an in-record flag cannot downgrade a protected record to 'unsigned, skip'."* That is **exactly** what a file-write attacker can do: `_requires_verification` decides whether a record must be signature-checked by reading **attacker-controlled in-record fields** (`payload["policy"]`, `ext["protected_cell"]`, the four `*_signature`/`file_fingerprint`/`ast_path` triggers). Rewrite `payload["policy"]` to a non-protected value, strip the ext triggers, recompute `content_hash`, re-chain → every predicate clause is False → the signature is **never examined**. Both `verify_integrity()` and `TrailVerifier.verify()` pass. The damning record is neutered to a benign unsigned row. **No HMAC key required.** Verified by PoC (`/tmp/attack_predicate.py`): `TrailVerifier.verify: PASSED` after neutering a protected `OVERRIDDEN_BY_OPERATOR` to `policy='benign-note'`. The head anchor does **not** save it: composed with the already-conceded snapshot/replay residual, anchor-ON also falls (`/tmp/attack_anchor_compose.py`). +- **Severity calculus:** the *exploit* requires raw file-write to `gov.db` — the same conceded C3 out-of-band capability that made **AUD-1 a post-1.0 non-blocker**. By the project's own yardstick the *code hardening* is legitimately post-1.0. But the *false docstring* is an honesty break (the same over-claim class POLICY-1/GOV-1 were): a shipping artifact (the docstring ships in the installed package) asserts a guarantee that does not hold. *Scope check (verified):* the **CHANGELOG makes no AUD-1 closure claim at all**, so it does not need correcting; the only other place the modify-to-unsigned variant is omitted is the `acdbff0` commit message (git history, not a shipped artifact). The fix is therefore confined to one docstring. **Fix the docstring now** to scope the guarantee honestly (in-place edit / reorder / renumber are caught by v3 seq-binding; modify-to-unsigned and tail-truncation are residuals of the conceded file-write tier, mitigated only by the opt-in head anchor and even then with the documented replay caveat). **Track the code hardening post-1.0:** derive the verification requirement from config/entity identity rather than the record being verified, or sign **all** appends so "unsigned" is itself tamper for the whole trail. + +--- + +## SHOULD-FIX before 1.0 (cheap honesty hygiene) + +- **README coached-cell — name the model-robustness limit explicitly.** `README.md:83`; code at `enforcement/engine.py:92`. *Downgraded from must-fix after reading the source directly:* the README is largely honest — it states the agent clears the gate by "explain[ing] itself convincingly" and that the wall is against *lazy* overrides ("raises the cost of lazy overrides without raising the cost of honest ones"), which discloses semantic persuasion. The gap is narrower than the subagent framed: it does not name the **prompt-injection / model-robustness** limit (a *malicious* injection, not honest persuasion, can fool the judge). That residual is honest in the `judge.py` docstring but absent from user-facing docs. Add one sentence to the known-limitations note (below). Not a blocker. +- **POLICY-1 — harden against aliased disabling markers.** `policy/evidence.py:29-59` (`_disabling_marker`). The gate matches only the **terminal name** against `{skip, skipif, xfail}`; a marker bound to a local/module alias — `skipper = pytest.mark.skip; @skipper` → `ast.Name("skipper")` — is not flagged, so a genuinely-skipped evidence test (`1 skipped`) keeps the boundary GREEN. This is an **under-match**, the precise failure the docstring claims to fail-closed against, and unlike the two *documented* residuals (module-level `pytestmark`, class-level `@skip` — genuinely parity-unfixable, they live outside the function source) this alias **is** in the function's `decorator_list` and is catchable on both gate paths. *Why should-fix not must-fix:* there are **zero shipped `@policy_boundary` decoration sites** in the tree today, so the 1.0 product has no live false-green from this — but it should be hardened before anyone adds a boundary. **Fix:** fail-closed on an evidence-test decorator whose terminal name is not a recognized non-disabling marker (the docstring already asserts the only legitimate decorators on evidence tests are pytest markers, so fail-closed-on-unknown is consistent with the stated design). Pin with a test. + +- **User-facing "Known security limitations" home.** AUD-1 HeadAnchor replay, ID-3 (unsigned probe when keyless), and the AUD-3 durability tier (synchronous=FULL / power-cut tail-loss) are honestly described **only** in source docstrings and the internal `release-1.0-risk-audit.md` — not in any artifact the user reads (README/CHANGELOG). A residual the user cannot see is itself an honesty gap. Add a short README/CHANGELOG section. (This also matters because of the disclosure decision below: if the internal audit doc is pulled, these residuals lose their *sole* home.) +- **ID-SEI-1 — undocumented `LEGIS_ALLOW_INSECURE_REMOTE_HTTP`** (`identity/loomweave_client.py:137-139`). TLS is the *only* response-integrity control on the SEI path (the request HMAC signs requests, nothing verifies responses — the ratified, documented model). This flag lets a **keyed, non-loopback** deployment talk to Loomweave over plaintext, so an on-path attacker can forge a `resolve` response into a **wrong-but-stable identity binding (identity_stable=True)** with no TLS break. Off-by-default and INSECURE-named, so **not a blocker**, but its binding-integrity blast radius is documented nowhere. Add a one-line warning log when it bypasses HTTPS on a keyed/non-loopback host + a sentence in the federation trust-model doc. +- **POLICY-1 fixture-auto-skip residual.** A test whose conftest fixture is edited to `pytest.skip()` never runs but its fingerprint is unchanged (fixture body lives elsewhere). Genuinely in the parity-unfixable class (out-of-band signal), so non-blocking — but currently **undocumented**; add it to the disclosed-residual list to keep the honesty claim complete. + +--- + +## POST-1.0 / tracked (non-blocking) + +- **F1 code hardening** — config/identity-derived verification requirement, or sign-all-appends (see F1 above). +- **JUDGE-4** — a coached transport error (`LLMTransportError`) propagates and writes **no** record (`engine.py:80`). Fail-closed at outcome (no accept), but contradicts the module's "exactly one append-only record, no silent path" guarantee — a failed override attempt leaves no trace. LOW. +- **hooks.py:59** — the SessionStart/MCP-boot freshness probe (`refresh_instructions`) is still **first-marker-only** (`_extract_marker_token`), the pattern INSTALL-1's commit fixed in `doctor`. On a split brain it silently no-ops (no warning); only operator-invoked `legis doctor` surfaces it. Functional impact low (re-injection can't collapse a split brain anyway), but INSTALL-1 patched the *gate* not the *trigger*. LOW. +- **ID-SEI-2** — `resolver.py:192` `alive` truthiness not type-checked (a hostile/buggy Loomweave returning `"false"` reads as alive). Gated by TLS trust; LOW. + +--- + +## DECISION FOR THE HUMAN (not the reviewer's to make) + +`docs/release-1.0-risk-audit.md` is **git-tracked and ships publicly**, and contains **end-to-end-reproduced attack recipes** — the POLICY-1 disable-after-pin sequence, the GOV-1 lineage-tamper-reads-green path, the AUD-1 delete-and-rechain method, and now (if this doc ships too) the JUDGE-3 / F1 mechanisms.

1.0 tidy doctor: - `--fix` is now the canonical repair flag; `--repair` stays a working alias (argparse dest `fix`), so no script breaks. - DoctorCheck gains a `repairable` bit; text view tags each problem `[fixed]` / `[auto-fixable]` / `[operator]` with footers that point auto-fixable items at `legis doctor --fix` and tell the operator that `[operator]` items need out-of-band config + a relaunch. JSON checks carry `repairable` additively. - `install.filigree_scope` is gated on filigree actually being installed (file-existence probe, no filigree import): the unscoped-binding warning only fail-closes against a server-mode filigree daemon, so it is noise when filigree is absent. When it fires, the message names it operator- owned (the `--filigree-url` is operator-pinned in wardline's `.mcp.json`) and stays repairable=False. tidy for 1.0 (version held at rc4 per the live-e2e gate): - README + doctor docstring use the canonical `--fix` spelling. - CHANGELOG [Unreleased] records the above. - .gitignore ignores `.claude/*.lock` (transient scheduled-tasks lock). - removed stray build artifacts (.coverage, coverage.json).

Adds docs/guide/: - configuration.md — the operator's governance-control reference: reconciles "zero human config" (the agent's experience) with the operator's two acts (choose the cell, hold the key); per-cell cost/buys table; the fail-closed routing default + resolution order; full LEGIS_* / OPENROUTER_* env-var reference grouped by purpose; and a separate, warning-carrying "dev-only / escape hatches" section for the LEGIS_UNSAFE_* / LEGIS_ALLOW_* flags. - reading-legis-output.md — organized by "where it surfaces / what it means / do I act": keeps the recorded Verdict (ACCEPTED/BLOCKED/OVERRIDDEN_BY_OPERATOR) distinct from the override_submit outcome envelope (ACCEPTED_SELF / ACCEPTED_BY_JUDGE / BLOCKED / ESCALATED_PENDING / NEED_INPUTS); covers scan outcomes, artifact/identity/lineage statuses, the override-rate gate, CI exit codes, doctor tags, and flags the only signals that need a human in real time. - README.md (index) + links from the top-level README. Every flag/enum/command cited was verified against source (e.g. dropped a spurious OPENROUTER_BASE_URL row that was a grep artifact of the DEFAULT_OPENROUTER_BASE_URL constant, not a real env var).

(Corrects the tag shipped in 84a8047.) - **`_filigree_installed` now mirrors filigree's real install predicate.** It was an AND requiring `.filigree.conf` AND a `config.json`; filigree's `find_filigree_anchor` (core.py:1046-1064) treats a project as installed if ANY of three markers is present: `.filigree.conf` (file), `.weft/filigree/` (dir), or `.filigree/` (dir) — never AND, and the store/legacy checks are `.is_dir()`, not a `config.json` `.is_file()`. The old AND would return "not installed" for confless / legacy / conf-only installs and SILENTLY DROP a real unscoped-binding warning where filigree genuinely is installed — the false-green the governance honesty discipline forbids. Tests updated to cover conf-only, confless-weft, and confless-legacy installs (the last is the live federation-legacy-path case). Full suite green (815 passed, 2 skipped), ruff + mypy clean.
