Fix governance-validation: exempt manifests from Check 3, drop duplicate checklists, run the in-tree action - #57
Conversation
…tree action `Anchor Drift / governance-validation` has been red since 2026-07-25. Baseline at 44f9c9f is 512 files scanned / 8 errors, which reproduces run 34815241312 exactly. The 8 errors are two distinct faults, both fixed here. 1. Check 3 (attestation) is unsatisfiable for markdown-form manifests. The section OPENER accepts `[attestation]`, `## Attestation` or `## ATTESTATION`, but the content test only matches a TOML assignment (`(proof|signature|verified|hash)\s*=`). A manifest that opens the block with a markdown heading therefore can never satisfy it. Manifests are already exempt from the identity and version checks; they were simply never exempted from this one. One clause closes it. Measured: 8 -> 4 errors. Conformance is unaffected: conformance/valid 8 scanned / 0 errors, conformance/invalid 10 scanned / 12 errors, byte-identical patched vs unpatched, and conformance/invalid/empty-attestation.a2ml still flags. 2. The remaining 4 errors are byte-identical duplicate files. `MAINTENANCE-CHECKLIST.a2ml` exists twice per member (md5 99d177ac for deno, haskell and rs; 863bcd28 for validate-action). The copy under `.machine_readable/policies/` passes; the copy under `docs/governance/` errors. Same bytes, opposite verdicts: `is_structural_identity` exempts the machine tree, where these files carry identity structurally (owning repo + path + filename) rather than via an in-file `name`/`agent-id` key. The file's own header declares it "machine-readable canonical" and its `companion-machine` points into `.machine_readable/policies/`, while its `source-human` points at `docs/maintenance/` rather than `docs/governance/` -- evidence the erroring copy was duplicated in. Removing it leaves the canonical copy where the validator already expects such files. Adding `name =` was rejected as the alternative: it would make the `docs/` copy diverge from a machine-tree twin that stays identity-less by design. Widening `is_structural_identity` to `docs/governance/` was also rejected: the two identity-less neighbours there, CRG-CRITERIA.a2ml and TSDM.a2ml, already pass by SHAPE via `is_contractile_shape`, so a path exemption is the wrong instrument and would silently exempt every future file dropped in that directory. 3. The validator jobs ran a published action that no longer matches this repo. All three pinned `hyperpolymath/a2ml-ecosystem/validate-action@aa4b836` -- the OLD repository name, resolving only through GitHub's rename redirect, at a SHA predating the monorepo consolidation. Any change to the in-tree validator was therefore inert: CI executed the published old copy, not this tree. `validate-action/action.yml` is `using: composite`, so `uses: ./validate-action` is a drop-in and every `with:` block transfers unchanged. This also retires the rename-redirect dependency and makes CI test what is actually in the tree. Measured on the assembled branch with the job's exact inputs (path ".", strict "true", the workflow's nine paths-ignore entries): 508 files scanned, 0 errors, rc=0.

Run required governance checks with trusted validator code.
If these jobs are required checks, do not let uses: ./validate-action determine their status after actions/checkout loads the pull-request ref. A contributor can change validate-action/action.yml or validate-a2ml.sh to bypass validation. Use a pinned trusted validator, or protect the validator files with required ownership review and a separate trusted workflow. Keep local-action conformance jobs non-required if they must test validator changes.

Scope the Check 3 exemption to recognised manifest paths.
is_manifest is classified from basename, but this condition suppresses the warning for every file named META.a2ml, AI.a2ml, or any *file.a2ml, regardless of its directory. If the rest of the file is valid, a non-manifest file can contain an empty [attestation] or ## ATTESTATION block and pass strict validation without the required attestation fields.
Require the documented manifest path and type before skipping Check 3. Avoid broad basename-only matches.

Follow-up to #57, which removed four byte-identical `MAINTENANCE-CHECKLIST.a2ml` duplicates. A fifth survived, hidden from the gate only by `paths-ignore: members/` in `anchor-drift.yml`. `members/tooling/vscode-a2ml/docs/governance/MAINTENANCE-CHECKLIST.a2ml` is md5 `99d177ac69836abbba1297baa25f034d` — identical to the four already removed, and identical to the canonical copy sitting **in its own directory** at `.machine_readable/policies/MAINTENANCE-CHECKLIST.a2ml`. ### Verified safe to delete, not assumed | check | result | |---|---| | Submodule or vendored tree? | No `.gitmodules` exists at all; every path under the member dir is a regular blob (`100644`/`100755`), no gitlink, no `linguist-vendored` | | Upstream to re-sync from? | `hyperpolymath/vscode-a2ml` returns 404 — folded into this monorepo by #23 | | References to the deleted path form? | Zero. Every reference in the tree names `.machine_readable/policies/` | | Canonical twin present? | Yes, same directory, same md5 | Two files matched a loose "vendored/upstream" grep and were checked individually: `QUICKSTART-MAINTAINER.adoc:128` is a dead link to the 404 upstream (separate fix), and `.github/SECURITY.md:210` is ordinary prose about dependency coordination. Neither is a vendoring marker. Hygiene only — this path is outside the gate's scope, so no check result changes. 🤖 Generated with [Claude Code](https://claude.com/claude-code) https://claude.ai/code/session_01HfgwLCdKNd5iZVo6VTiSim Co-authored-by: Claude Opus 5 <noreply@anthropic.com>

Anchor Drift / governance-validationhas been red since 2026-07-25. This makes it green, measured rather than predicted.Baseline
Fresh shallow clone at
44f9c9fc, run with the job's exact inputs (path: ".",strict: "true", the ninepaths-ignoreentries copied from the workflow):512 files scanned / 8 errors — reproduces live run
34815241312exactly, so the instrument is sound.Those 8 errors are two unrelated faults, four each.
1. Check 3 (attestation) is unsatisfiable for markdown-form manifests
validate-a2ml.sh:320. The section opener accepts[attestation],## Attestationor## ATTESTATION; the content test accepts only a TOML assignment,(proof|signature|verified|hash)\s*=. A manifest that opens the block with a markdown heading can therefore never satisfy it — the guard asks a different question than its consumer.Manifests are already exempt from the identity check (
:279) and the version check (:284). They were simply never exempted from this one. One clause closes it.Measured: 8 → 4 errors. Conformance unaffected —
conformance/valid8 scanned / 0 errors,conformance/invalid10 scanned / 12 errors, byte-identical patched vs unpatched, andconformance/invalid/empty-attestation.a2mlstill flags.2. The other 4 errors are byte-identical duplicate files

is_structural_identity(:270), which exempts the machine tree because files there carry identity structurally — owning repo + path + filename — rather than via an in-filename/agent-id.The erroring copy declares itself a machine-tree file: its header reads
# Cross-repo maintenance baseline (machine-readable canonical)and itscompanion-machinepoints into.machine_readable/policies/. Itssource-humanpoints atdocs/maintenance/, notdocs/governance/— evidence it was duplicated in. Removing it leaves the canonical copy exactly where the validator already expects such files.Two alternatives were measured and rejected:
name =to the four copies (also reaches 0 errors) — but it makes thedocs/copy diverge from a machine-tree twin that stays identity-less by design, leaving two near-copies free to drift.is_structural_identitytodocs/governance/— the wrong instrument. The two identity-less neighbours in that directory,CRG-CRITERIA.a2mlandTSDM.a2ml, already pass by shape viais_contractile_shape(:242), not by path. A path exemption would also silently exempt every future file dropped there.MAINTENANCE-CHECKLIST.adocis untouched and stays.3. The validator jobs ran a published action that no longer matches this repo
All three pinned:
That is the old repository name, resolving only through GitHub's rename redirect, at a SHA predating the monorepo consolidation. Consequence: any change to the in-tree validator was inert — CI executed the published old copy, not this tree. Fix 1 alone would have changed nothing the gate runs.
validate-action/action.ymlisusing: composite, souses: ./validate-actionis a drop-in and everywith:block transfers unchanged. Lines 90, 115 and 132. This also retires the rename-redirect dependency and makes CI test what is actually in the tree.Result on the assembled branch
Conformance under the branch validator:
valid8/0,invalid10/12, negative fixture still flags.anchor-drift.ymlparses withjobsa non-empty map.Notes
Merging nothing — opened for review per standing policy.
Follow-up, deliberately not in this PR:
validate-a2ml.shand theINPUT_*names still carrya2ml. Renaming those belongs behind the dual-accept-validators step in the.a2ml→.deedplan, and the.deedgrammar sits in another lane.🤖 Generated with Claude Code
