Why

Part of the Instinct external GA validator epic (control repo wave-av/claude-workstation,
governance/plans/instinct-ga-validator/E1-HANDSHAKE.md, P2 row 3). wave-av/sdks is currently
the only repo in the fleet that emits a schema-shaped ga-evidence.json for the WAVE GA
readiness gate (see its scripts/ga/registry-cleanroom.mjs /
.github/workflows/registry-cleanroom.yml). This PR gives api-spec its own producer, on the
same pattern, for the two platform-scoped criteria in
governance/ga-gate/spec/WAVE-GA-gate-spec-v1.0.0.json that name api-spec in
owning_surface_or_repo_class: CONTRACT-001 and COMPAT-001.

What each check verifies — and what stays unknown

CONTRACT-001 ("one promoted contract is the source of truth across spec, gateway, registry,
MCP, SDK and CLI") — scripts/ga/check-CONTRACT-001.shcontract-001-check.mjs. This
reuses this repo's own .github/scripts/published-drift-compare.mjs /
published-drift-normalize.mjs rather than re-deriving OpenAPI-diff normalization (that
normalizer exists because, per its own header, "all 72 shared operations report a difference for
enrichment reasons alone" without it). Two sub-checks, both required for pass:

  • operation-parity — zero unexplained repo-only/live-only operations (CONTRACT-001's own text),
    computed via the existing compare() with the existing allowlist and draft-suppression rules.
  • content-digest — two independent sha256 digests, one walking the repo's copy of every shared
    operation post-normalization, one walking the live document's copy the same way, must be
    byte-identical.
    If the live document at https://api.wave.online/openapi.json cannot be fetched or parsed, the
    check exits 2 (could not run) and is reported unknown — never pass.

COMPAT-001 ("no unapproved breaking change; deprecations carry notice") —
scripts/ga/check-COMPAT-001.shcompat-001-check.mjs. Resolves the highest v* tag on
origin, extracts openapi.yaml at that tag and at HEAD via git show, and runs
oasdiff breaking -o ERR -f json (oasdiff on PATH if present, else go run github.com/oasdiff/oasdiff@v1.29.1 — CI has no oasdiff binary preinstalled so it always takes
the pinned go run path; go version is preinstalled on ubuntu-latest). pass only when zero
ERR-level (breaking) findings. The deprecation-notice / migration-path / support-window half of
COMPAT-001's pass condition is never machine-verified by this repo
— every result for this
criterion carries failing_checks: ["deprecation notice/migration path not machine-verified"]
and can never read as a full pass, per the honesty rules in this task's brief.

Both criteria's status is computed from a real run every time — never hardcoded.

Receipts

Schema-valid real run:

$ node scripts/ga/ga-evidence.mjs --out-dir ga-out
...
CONTRACT-001: FAIL
COMPAT-001: FAIL
$ node governance/bin/ga-gate.mjs validate ga-out/wave-av__api-spec.ga-evidence.json
ok    ga-out/wave-av__api-spec.ga-evidence.json

Both criteria are honestly FAIL today: CONTRACT-001 because the live gateway currently serves
operations this repo doesn't declare and vice versa (33 findings) plus real shared-operation
content drift; COMPAT-001 because 9 real ERR-level breaking changes exist between the v1.0.0
release tag and HEAD (e.g. new required request properties on POST /clips, a removed
GET /search/quick). This is not a bug in the check — it is the real state of this repo, and
proves the gate is not hardcoded to pass.

Deliberately-broken input flips a check (the "gate that cannot fail is not a gate" drill):

$ GA_COMPAT_BASE_TAG="$(git rev-parse HEAD)" node scripts/ga/compat-001-check.mjs
PASS COMPAT-001/breaking-changes: zero breaking (ERR-level) changes between <HEAD> and HEAD (...)
$ echo exit=$?
exit=0

$ node scripts/ga/compat-001-check.mjs   # no override — real v1.0.0 baseline
FAIL COMPAT-001/breaking-changes: 9 breaking (ERR-level) change(s) between v1.0.0 and HEAD: ...
$ echo exit=$?
exit=1

Comparing HEAD against itself (a deliberately trivial baseline) reports PASS/exit 0; switching
back to the real release tag flips the same check to FAIL/exit 1 — proof the status is
computed from the diff's actual content, not a canned string. Separately verified: an unreachable
live URL (GA_CONTRACT_LIVE_URL=...not-a-real-path...) and a nonexistent tag
(GA_COMPAT_BASE_TAG=v99.99.99-does-not-exist) both exit 2 / UNKNOWN, never pass.

Delivery path

This workflow uploads ga-out/ as the ga-evidence-api-spec build artifact on every PR,
workflow_dispatch, and a daily 09:23 UTC schedule. It does not open a PR into
claude-workstation's governance/ga-gate/evidence/incoming/ — that intake requires a
cross-repo write credential this repo does not hold today, and per that directory's own README
the hand-off is "the owning repo's own CI ... opens a PR to this repo," a separate, deliberately
credential-gated step tracked outside this change.

Scope and safety

Public repo: no internal hostnames, no partner names, no secrets in any file or here. Live probes
are unauthenticated, read-only GETs (api.wave.online/openapi.json, already public); no
Doppler, no writes. ga-out/ is gitignored. Not merging this PR — opening for review only.

Note

Medium Risk
Introduces live production OpenAPI probing and semver breaking-change gating in CI; misconfiguration could hide real failures or create noisy false reds on scheduled runs, though PR enforcement is deliberately softened for exit 1.

Overview
Adds a GA evidence pipeline for wave-av/api-spec so CONTRACT-001 and COMPAT-001 produce schema-shaped ga-evidence.json (mirroring wave-av/sdks), with ga-out/ gitignored and npm run test:ga for the new checks.

CONTRACT-001 reuses existing published-drift-* logic: operation parity vs the live gateway OpenAPI (with allowlist/draft rules) plus independent normalized content digests that include reachable internal $ref targets so component-only drift is not missed.

COMPAT-001 compares openapi.yaml at the highest v* tag vs HEAD via pinned oasdiff (PATH, GA_OASDIFF_CMD, or go run), disables external $ref resolution in CI, and never reports a full pass because deprecation/migration policy is explicitly unverified.

ga-evidence.mjs aggregates both checks into ga-report.json and wave-av__api-spec.ga-evidence.json with shared fingerprints and fail-closed exit codes (0/1/2). The new ga-evidence workflow runs on PRs, schedule, and workflow_dispatch, uploads the artifact, and Enforce fails on exit 2 everywhere; on pull_request only, exit 1 (live criterion red) is a warning so PRs are not blocked by production surface state.

Summary by Sourcery

Add an honest, artifact-producing GA readiness pipeline for api-spec that validates contract consistency and compatibility without treating unverified criteria as passes.

New Features:

  • Add a GA evidence producer for CONTRACT-001 and COMPAT-001 with schema-shaped evidence and detailed reports.
  • Check live contract parity and normalized content digests against the published OpenAPI document.
  • Check breaking changes between the latest version tag and HEAD using oasdiff while explicitly reporting deprecation-policy coverage as unverified.

Bug Fixes:

  • Prevent production-surface criterion failures from failing pull-request jobs while continuing to fail jobs when evidence generation cannot run or fails on non-PR triggers.
  • Prevent referenced component schema changes from being missed by contract content-digest comparisons.

Enhancements:

  • Reuse existing published-contract drift comparison and normalization rules for GA contract validation.
  • Add deterministic evidence fingerprints that include check details and reachable referenced content.
  • Refuse redirects and external references during live contract and OpenAPI analysis for safer CI execution.

CI:

  • Run GA evidence generation on pull requests, manual dispatches, and a daily schedule, uploading the resulting evidence artifact.
  • Add hermetic Node test coverage for GA checks, baseline tag selection, command resolution, evidence status derivation, and fingerprint behavior.

Tests:

  • Add offline tests covering contract parity, referenced-schema drift, compatibility tool resolution, and evidence result construction.

Chores:

  • Keep cross-repository evidence intake into the governance repository as a separate credential-gated follow-up.

Review in cubic

Addendum — 92a9f0f

The Enforce step previously failed this PR's job on ANY non-zero exit code from the GA evidence producer, including exit 1, which means "a live GA criterion currently fails against the running production surface." Verified live on 2026-09-05: both CONTRACT-001 and COMPAT-001 fail today, so this PR's job was red purely from live-surface state, unrelated to any diff in this branch. That is not a property of the PR's changes.

This commit passes EVENT: ${{ github.event_name }} alongside the existing exit-code output into the Enforce step's env: block. On pull_request, exit 1 now emits a ::warning and exits 0, keeping the job green while still surfacing the failing criterion in the log, job summary, and uploaded artifact. Exit 2 (the producer could not run at all) and exit 1 on any other trigger (schedule, workflow_dispatch, push) still emit ::error and fail the job exactly as before — those cases genuinely indicate the gate itself is untrustworthy, not just that a live criterion is red. The header comment and the Enforce step's inline comment were both updated to state this contract.


CodeAnt-AI Description

Add automated GA evidence reporting for the API contract and release compatibility criteria

What Changed

  • Generates schema-compatible GA evidence and detailed reports for CONTRACT-001 and COMPAT-001
  • Checks that the published API has no unexplained operations or content drift, including changes hidden behind referenced schemas
  • Compares the current OpenAPI specification with the latest version tag to detect breaking changes
  • Reports compatibility as unknown when deprecation and migration requirements cannot be verified instead of claiming a full pass
  • Runs the checks on pull requests, daily, or manually; live criterion failures warn on pull requests while unavailable checks fail the job
  • Adds offline tests for tag selection, command parsing, referenced-schema detection, status reporting, and evidence fingerprints
  • Prevents external schema references from making CI fetch attacker-controlled URLs

Impact

✅ Traceable GA readiness evidence
✅ Earlier detection of API contract drift
✅ Fewer unnoticed breaking API changes
✅ Safer pull-request validation

wave-av/sdks is currently the only repo emitting a schema-shaped ga-evidence.json for the
WAVE GA readiness gate. This adds api-spec's own producer for the two platform criteria this
repo owns: CONTRACT-001 (does the declared contract match what the gateway actually serves,
reusing this repo's own published-drift comparator) and COMPAT-001 (zero breaking changes vs
the last release tag, via oasdiff). Status is always computed from a real run, never hardcoded;
COMPAT-001 never claims the unverified deprecation-notice half of its pass condition.

Verdict: Not approved

Macroscope's review found this PR not approvable — This PR adds a substantial, network-dependent GA evidence workflow and new compatibility/contract-checking components that run on every pull request. The unresolved policy of failing pull requests when external checks cannot run, combined with the lack of path filtering, requires human review.

Code Review ✅ Approved 2 resolved / 2 findings

Adds a fail-closed GA evidence pipeline for CONTRACT-001 and COMPAT-001 with schema-valid output, reusing existing drift-comparison logic and pinned oasdiff for breaking-change detection. The new scripts/ga/*.mjs modules contain non-trivial status-derivation and command-resolution logic but ship without unit tests — consider adding coverage for buildContractRow/buildCompatRow edge cases and resolveOasdiffCmd/resolveBaseTag overrides. Additionally, GA_OASDIFF_CMD splits naively on spaces, which could silently break quoted paths if the variable is ever wired into CI.

✅ 2 resolved
Quality: New GA evidence scripts have no unit tests

📄 scripts/ga/contract-001-check.mjs:1-15 📄 scripts/ga/compat-001-check.mjs:1-15 📄 scripts/ga/ga-evidence.mjs:1-15
The sibling modules these scripts reuse and depend on (.github/scripts/published-drift-compare.mjs, published-drift-normalize.mjs) have dedicated .test.mjs coverage, but the three new scripts/ga/*.mjs files — which contain non-trivial logic (status derivation, fingerprinting, oasdiff invocation/parsing, tag resolution) — ship with none. Add unit tests at least for buildContractRow/buildCompatRow status derivation and resolveOasdiffCmd/resolveBaseTag edge cases (no tag, no oasdiff, override present) so regressions in the pass/fail/unknown logic are caught before they silently change what CI reports.

Edge Case: GA_OASDIFF_CMD split on spaces breaks quoted args

📄 scripts/ga/compat-001-check.mjs:64-66
process.env.GA_OASDIFF_CMD.split(' ').filter(Boolean) naively splits on spaces, so an override like GA_OASDIFF_CMD="docker run --rm -v /path with spaces:/data oasdiff" would be split incorrectly. This is low-risk today since the variable isn't set anywhere in the CI workflow (only documented as a manual/local override), but if it's ever wired into CI with a multi-word command containing quoted paths, this will silently produce a broken spawnSync invocation that surfaces as a confusing couldNotRun error rather than the real cause.

…gerprint gaps, add tests

Addresses review threads on the GA evidence producer (PR #86):

- compat-001-check.mjs: pass --allow-external-refs=false to `oasdiff breaking`
  (coderabbit Security/Major + cubic P1) so a PR-supplied openapi.yaml with an
  external $ref cannot make the CI runner fetch an attacker-controlled URL.
- compat-001-check.mjs: replace GA_OASDIFF_CMD.split(' ') with a real
  splitShellCommand() argv tokenizer (quotes + backslash escapes), fixing the
  quoted-path corruption gitar and cubic both flagged.
- contract-001-check.mjs: fold reachable $ref content (resolveJsonPointer +
  collectReachableRefs) into the per-operation content digest, so a component
  schema change behind an unchanged $ref is no longer invisible to
  CONTRACT-001 (cubic P1).
- contract-001-check.mjs: operation-parity now only counts
  undocumented-live/unpublished-repo findings, not shared-drift (already
  content-digest's job), so the two sub-checks name distinct failures (cubic
  P2).
- ga-evidence.mjs: fingerprintPayload now includes each check's `detail` text,
  not just `ok`, so an evidence-relevant change that doesn't flip a boolean
  no longer gets deduplicated as stale evidence (cubic P2). Also adds the
  isMain guard this file was missing, so importing it for buildContractRow/
  buildCompatRow no longer runs the live producer as a side effect.
- ga-evidence.yml: reword the job-summary and Enforce success text so exit 0
  is never read as COMPAT-001 == pass (cubic P3).
- Add scripts/ga/{compat-001-check,contract-001-check,ga-evidence}.test.mjs
  (35 assertions, hermetic/offline/no shared-tag mutation) plus a `test:ga`
  npm script, closing the no-test-coverage asks from gitar and cubic.

Declined: cubic's ga-evidence.yml:27 suggestion to path-filter the workflow
and make producer exit 2 advisory on pull_request — the PR-job contract
(exit 2 always fails, exit 1 warns on PR) is a deliberate, already-reviewed
design documented in this same file's header; changing trigger/enforcement
semantics is out of scope here.

Addressed in 03d0200 (pushed to this branch). Per-thread disposition:

  1. gitar-bot, scripts/ga/contract-001-check.mjs:15 — "no unit tests" → tested. Added scripts/ga/contract-001-check.test.mjs covering resolveJsonPointer/collectReachableRefs and run()'s operation-parity/content-digest independence, including the exact reachable-ref-digest case below.

  2. gitar-bot, scripts/ga/compat-001-check.mjs:66GA_OASDIFF_CMD.split(' ') breaks quoted args → fixed, not just documented. Added a real splitShellCommand() argv tokenizer (quotes + backslash escapes), exported and unit-tested in scripts/ga/compat-001-check.test.mjs.

  3. coderabbitai, scripts/ga/compat-001-check.mjs:84 — SSRF via external $ref in oasdiff breakingfixed. Added --allow-external-refs=false to the oasdiff invocation.

  4. cubic-dev-ai P1, scripts/ga/contract-001-check.mjs:163 — referenced-schema drift invisible when the $ref pointer is unchanged → fixed. Added resolveJsonPointer + collectReachableRefs and folded reachable $ref content into the per-operation content digest; contract-001-check.test.mjs has a dedicated test where the operation object is byte-identical on both sides but the referenced component schema differs, and content-digest now correctly flips to fail.

  5. cubic-dev-ai P1, scripts/ga/compat-001-check.mjs:84 — same SSRF finding as feat: add capabilities.json (platform-registry Phase D) #3fixed by the same --allow-external-refs=false change.

  6. cubic-dev-ai P2, .github/workflows/ga-evidence.yml:27 — path-filter the workflow / make producer exit 2 advisory on pull_requestdeclined. The PR-job contract (exit 2 always fails the job on every trigger, exit 1 is ::warning on pull_request) is a deliberate, already-reviewed design, documented in this same file's own header ("PR CONTRACT" note). Changing trigger/enforcement semantics is out of scope for this PR; path-filtering is a reasonable follow-up but a separate change with its own branch-protection implications.

  7. cubic-dev-ai P2, scripts/ga/contract-001-check.mjs:173operation-parity also fails on shared-drift findings, double-counting what content-digest already reports → fixed. operation-parity now filters to undocumented-live/unpublished-repo findings only; contract-001-check.test.mjs has a dedicated test asserting parity stays ok:true on a shared-drift-only difference while content-digest correctly fails.

  8. cubic-dev-ai P2, scripts/ga/ga-evidence.mjs:194 — fingerprint payload doesn't change when only unmatched-operation findings change → fixed. fingerprintPayload now includes each check's detail text (not just ok), tested in ga-evidence.test.mjs (two rows with the same booleans but different detail now produce different fingerprint payloads).

  9. cubic-dev-ai P2, scripts/ga/contract-001-check.mjs:1 — no automated tests (duplicate of ci(F6): foundation-gate + CODEOWNERS #1) → tested, same coverage as ci(F6): foundation-gate + CODEOWNERS #1.

  10. cubic-dev-ai P3, .github/workflows/ga-evidence.yml:89 — exit-0 wording overstates COMPAT-001 as passfixed. Reworded both the job-summary exit-code line and the Enforce step's success message to state COMPAT-001 remains unknown unless a breaking change is found.

  11. cubic-dev-ai P3, scripts/ga/compat-001-check.mjs:107 — add unit coverage for status/failure paths → tested. ga-evidence.test.mjs covers buildCompatRow's couldNotRun/clean-unknown/fail branches directly; compat-001-check.test.mjs covers resolveBaseTag's tag-selection edge cases (no tag, one tag, highest-semver, non-v-prefixed) against a disposable scratch git repo, and resolveOasdiffCmd's PATH-based resolution order (override / oasdiff / go / neither).

  12. cubic-dev-ai P3, scripts/ga/compat-001-check.mjs:65 — same GA_OASDIFF_CMD split issue as chore(governance): add AGENTS.md + CHANGELOG baseline #2fixed, same splitShellCommand() change.

Also fixed in passing while adding tests: ga-evidence.mjs was missing the isMain guard the other two scripts have, so importing it for buildContractRow/buildCompatRow ran the live producer (network fetch, git tag read, oasdiff invocation) as an import side effect — now guarded.

Verified: node --test "scripts/ga/**/*.test.mjs" → 35/35 passing (also added as npm run test:ga); node --test ".github/scripts/*.test.mjs" → 39/39 passing (no regression in the pre-existing drift-comparator suite this file reuses); npm run lint → valid (pre-existing warnings only, unrelated to this change); actionlint .github/workflows/ga-evidence.yml → clean.

Semgrep identified an issue in your code:
Possibility of prototype polluting function detected. By adding or modifying attributes of an object prototype, it is possible to create attributes that exist on every object, or replace critical attributes with malicious ones. This can be problematic if the software depends on existence or non-existence of certain attributes, or uses pre-defined attributes of object prototype (such as hasOwnProperty, toString or valueOf). Possible mitigations might be: freezing the object prototype, using an object without prototypes (via Object.create(null) ), blocking modifications of attributes that resolve to object prototype, using Map instead of object.
