feat(ci): add structural workflow-policy YAML authority (S4) - #505
Conversation
Adds a real yaml-parser-based structural validator for GitHub Actions workflow files, replacing the regex/string-split-only checks that existed previously (tests/utils/workflowPolicyParsers.ts). Checks top-level/job-level permission write scopes against an explicit allowlist, needs-graph resolution and cycles, SHA-pinned action references, the ci-success aggregator's needs list staying in sync with actual gating jobs, and a publishing boundary restricting contents:write to an explicit allowlist. Wired into the quality job in ci.yml and into local pre-push admission for workflow-file changes. Also fixes one pre-existing inconsistency the new gate caught: the signatures job's checkout step was missing its trailing SHA-pin comment that every other checkout call has.
Unit tests for every check in scripts/workflow-policy-check.mjs via direct function imports (DI style, no filesystem fixtures): top-level and job-level permission scopes, needs-graph resolution and cycle detection, action-pin format (including the dtolnay/rust-toolchain "# stable" non-SemVer exception), the ci-success aggregator's needs set, the publishing boundary, trigger recognition, YAML-level parse errors (duplicate keys), anchor/alias resolution, and multi-file aggregation.
Regenerated via scripts/sync-readme-metrics.mjs to include the new workflow-policy-check test file (579 test files, 7032+ tests).

This PR adds a robust YAML-parser-based workflow policy validator that enforces critical security controls for GitHub Actions workflows. The implementation is production-ready with comprehensive test coverage (27/27 tests passing) and proper CI integration.
Security controls validated:
- Top-level permissions restricted to
{contents: read}or scalarread-all - Job-level write permissions limited to explicit allowlist by workflow/job
- Publishing authority (
contents: write) restricted to designated release jobs only - Action references require SHA pins with trailing comments
- Needs graph validation prevents cycles and dangling references
- CI success aggregator synchronization with gating jobs
Quality highlights:
- Well-structured code with dependency injection for testability
- Comprehensive test suite covering normal paths, edge cases, and error conditions
- Proper integration into CI pipeline and local pre-push checks
- Successfully caught and fixed pre-existing inconsistency (missing SHA pin comment in signatures job)
The implementation correctly addresses the gap identified in the PR description and provides a real structural admission gate rather than regex-based validation.

Codecov Report✅ All modified and coverable lines are covered by tests. 📢 Thoughts on this report? Let us know! |
Root-cause fixes for the review wave on PR #505: filename extraction now uses basename() instead of a hardcoded "/" split (broke on Windows-style paths); action-pin enforcement walks the parsed step tree instead of a raw regex, so flow-mapping steps (- { uses: ... }) can no longer bypass SHA-pin checks; scalar permissions: write-all is now explicitly rejected by both the job write-scope allowlist and the publishing-boundary check instead of being silently skipped; ci-success.needs now normalizes a bare-string value before building its comparison Set, instead of decomposing it into characters; composite actions under .github/actions/**/action.yml are now discovered and pin-checked (local admission route extended to match), scoped to only the pin check since they have no jobs/permissions/needs. Also fixes a related latent bug the write-all fix exposed: permissionEntries did not resolve YAML anchors/aliases before classifying a permissions block, so an aliased *perms reference was misread as an unsupported scalar. QNBS-v3 comments added to test groups per CodeRabbit nitpick.
chatgpt-codex-connector (P1): checkAggregatorNeeds only verified that ci-success.needs lists every gating job by name, not that the aggregator's own if: always() run script actually evaluates needs.<job>.result for each of them. Since if: always() disables GitHub's automatic dependency-failure gating, a job added to needs: without a matching result check would run but never fail the aggregator. Scoped to only fire when if: always() is present — without it, GitHub's default gating already covers this, so no result-check is required.

Fixes 6 chatgpt-codex-connector findings against commit cff962a: alias resolution inside permission-map values (not just whole-block aliases), job-level reusable-workflow uses: references were never pin-checked, if:always() result-checks accepted a bare log statement instead of requiring actual failure control, composite-action discovery only probed one directory level, docker:// references got an unconditional pin exemption regardless of tag-vs-digest, and an aliased uses: reference bypassed the pin check entirely. Introduces a single resolveNode() helper reused at both alias call sites instead of patching each site independently. Also corrects workflow-policy-check.d.mts, which had fallen out of sync with the recursive Dirent-based readdirSync signature listActionFiles now requires, and re-syncs the README test-metrics badge for the 9 new regression tests (55 total, up from 46).

…heck Fixes review-wave-4 findings (chatgpt-codex-connector + CodeRabbit) against commit a792127: an aliased whole job (job: *base) was an Alias node without .get(), so write-scope, needs-graph, publishing- boundary, and job-level uses: checks silently skipped it; an aliased steps: list or individual step had the same gap in the pin check. Fixed at the root — jobMap() now resolves every job value, and a new resolveSteps() helper resolves both a steps: list and each item in it, so every downstream consumer (collectWorkflowSteps, collectActionSteps, collectNeedsResultReferences) is correct for free without per-site patching. Also: the if:always() result-check no longer treats a "# exit 1" inside a shell comment as real failure control (strips whole-line comments before matching; causal linkage to an unrelated branch remains a documented, deliberate heuristic limit — not a shell parser). And ci-success.needs now excludes the full transitive downstream closure (BFS from ci-success), not just direct dependents, fixing a false "missing gating job" report for a job like smoke that needs deploy that needs ci-success. Also fixes two hardcoded "/" path-separator assumptions in the listActionFiles tests (Windows-unsafe) by matching via node:path's join() instead, and re-syncs the README test-metrics badge (59 tests, up from 55).

Fixes 2 review-wave-5 findings (chatgpt-codex-connector) against commit 8c5ad4f: 1. The workflow-policy:check step lived inside the "quality" job, AFTER that job's own `uses: ./.github/actions/setup` step already ran the composite action. A PR that tampers with that composite (or any other workflow/action file) would have its tampered code execute before the gate could reject it — the same TOCTOU class the "security" job's own earlier `uses: ./.github/actions/setup` at line 47 was exposed to, since "security" has no needs: at all and runs first. Fixed by adding a new "workflow-policy" job with no dependencies that never touches the governed composite (uses only external, SHA-pinned actions directly to set up pnpm/Node), and making "security" (and therefore everything downstream that already depends on quality/security) wait for it. Removed the now- redundant duplicate check inside "quality". Wired workflow-policy into ci-success's needs and its if:always() result-check script — required by the checker's own aggregator-sync rule, a useful dogfooding forcing function that caught this immediately. 2. The if:always() result-check only recognized always() as a condition overriding GitHub's default success-gating. failure() and cancelled() (including negated !cancelled()) have the same effect and were invisible to the check, so an aggregator gated by e.g. if: failure() could pass this policy gate while still letting a failed prerequisite's result go unchecked. Generalized to jobHasNonDefaultGatingCondition() matching any of the three. Re-syncs the README test-metrics badge (61 tests, up from 59).

…olicy job tests/unit/workflowPolicy.test.ts's "keeps required and advisory job authority explicit" test hardcodes the exact ci-success.needs array read from the real ci.yml. 3e0c110 added the workflow-policy prerequisite job to that array (correctly — required by S4's own aggregator-sync rule) but didn't update this pre-existing, untouched regex-based test, so CI's Quality Gate failed on the exact same file the earlier fix was meant to protect.

Fixes 6 bounded findings (chatgpt-codex-connector + CodeRabbit) against commit e9f4bf2: 1. The new workflow-policy job's own `pnpm install --frozen-lockfile` could execute repository-controlled lifecycle scripts (postinstall, .pnpmfile.cjs hooks) before the gate evaluates anything — a PR adding a malicious lifecycle hook could act before the check runs. Added --ignore-scripts --ignore-pnpmfile. 2. ci-success.if aliased from another job's condition (if: *cond) was an unresolved Alias node, invisible to the always/failure/cancelled detection. 3. docs/CI.md's job table, gate-authority list, and ASCII graph still showed security as the graph root; updated to show workflow-policy as the new prerequisite, plus a note on why it bypasses the governed composite. 4. listActionFiles' recursive walk didn't check isSymbolicLink() — a tracked directory replaced by a symlink pointing outside .github/actions would be silently skipped rather than rejected. Now throws, and checkAllWorkflows fail-closes that into a real policy failure instead of crashing. 5. needs: lists shared via an anchor/alias (b.needs: &deps [a]; c.needs: *deps) hit the same unresolved-Alias gap as the earlier permissions/uses fixes — closed with one new resolveNeedsList() helper reused at all 3 needs-reading call sites (checkNeedsGraph, computeAggregatorDescendants, checkAggregatorNeeds). 6. Docker-based composite actions (runs.using: docker, runs.image: docker://...) have no steps: at all, so their own image reference was invisible to any pin check. Added a dedicated check reusing checkUsesRef, with a Dockerfile-build exemption (no registry ref to pin) alongside the existing local-action exemption. Deferred (tracked in a new issue, not fixed here — see the linked comment replies): (a) `success() || <other-condition>`-style compound if: expressions can still bypass default gating in ways a function-name-substring heuristic can't catch without a real GitHub Actions expression-language parser; (b) mutation.yml, storybook-debug.yml, voice-nightly.yml, and tauri-build.yml also invoke the governed composite without an equivalent policy gate — real, but a materially larger change (a gate per workflow, or a shared reusable-workflow gate) than this successor PR's own scope. Re-syncs the README test-metrics badge (69 tests, up from 61).
Real CI failure on 05d7e84: the workflow-policy job's `pnpm install --frozen-lockfile --ignore-scripts --ignore-pnpmfile` succeeds, but the next step's `pnpm run workflow-policy:check` failed with ERR_PNPM_VERIFY_DEPS_BEFORE_RUN ("The list of pnpmfiles changed"). This repo has no .pnpmfile.cjs at all — merely passing --ignore-pnpmfile changes pnpm's recorded install fingerprint, which then mismatches what `pnpm run`'s own pre-run consistency check expects. Sidestepped by invoking `node scripts/workflow-policy-check.mjs` directly, which never goes through pnpm's run machinery at all.

…dary Fixes 3 findings (chatgpt-codex-connector) against commit c8bd941: 1. checkUsesRef's `./` exemption trusted ANY local reference unconditionally, but listActionFiles only scans `.github/actions/**` — a workflow could add `uses: ./ci/setup` (or any other local path) and its own unpinned/mutable references would never be checked. Restricted the exemption to `./.github/actions/` specifically; anything else now fails with an explicit "outside the governed directory" message. 2. checkPublishingBoundary authorized tauri-build.yml's release job by (filename, job-id) alone, without verifying its if: condition still restricts it to a tag push. Loosening or removing that condition would pass the gate while exposing contents:write on a manual/branch run. Now also verifies the allowlisted job's if: condition (alias-resolved) matches a tag-only pattern. 3. AGENTS.md's Pipeline Graph and Jobs table still showed security as the root and omitted workflow-policy (docs/CI.md was already fixed in 05d7e84, this file wasn't). Deferred (issue #506, Finding C): the workflow-policy job's own definition and script are sourced from the same PR ref it polices — a sufficiently adversarial PR could tamper with the gate itself, not just the composite it protects. Same class of problem as #503/#504: closing it requires a different trust architecture (pull_request_target, required-workflow rulesets), not more checker code. The gate remains fully sound for its primary threat model (unpinned/floating references, accidental or upstream supply-chain); the residual gap is a sophisticated malicious-insider scenario already mitigated in practice by required human review of workflow-file changes. Re-syncs the README test-metrics badge (71 tests, up from 69).

Summary
Adds a real YAML-parser-based structural validator for GitHub Actions workflow files and composite actions (
scripts/workflow-policy-check.mjs), closing a gap identified during the post-#477 reconstruction reconciliation program: the only prior workflow-policy check (tests/utils/workflowPolicyParsers.ts) works via regex/string-splitting, not a real parser, and is test-only rather than a CI/local-admission gate.What it checks
Using
yaml'sparseDocument(YAML 1.2 core schema) against every.github/workflows/*.ymland.github/actions/**/action.ymlfile, with aliases (&anchor/*alias) resolved at every container and scalar boundary (job values,permissions,needs,if,steps,uses):permissionsmust be exactly{contents: read}or the scalarread-all.write-allis rejected the same as an unallowlisted mapping form.needs:references resolve to real jobs (including through aliased needs lists); cycles are detected; the required aggregator's downstream closure (direct and transitive) is correctly excluded from what it must depend on.uses:reference (step-level, job-level reusable-workflow, and Dockerruns.image) must pin a 40-hex-char SHA or an immutable@sha256digest, walking the parsed tree so block/flow-mapping/aliased forms can't bypass it. Local references are restricted to the governed./.github/actions/directory (the only pathlistActionFilesscans) and recurse to any depth, rejecting any symlink found along the way.✅ CI Successaggregator'sneeds:list is checked against actual gating jobs; if itsif:condition overrides GitHub's default success-gating (always()/failure()/cancelled(), aliased or not), its run script must explicitly check every gating job's.result.contents: write, and an allowlisted job'sif:condition must still verifiably restrict it to a tag push — loosening that condition no longer silently passes by job name alone.workflow-policyCI job with no dependencies, before any other job invokes the governed./.github/actions/setupcomposite, using only external SHA-pinned actions (never that composite) for its own setup with lifecycle scripts disabled.Known, deliberately deferred limitations
This gate is sound for its primary threat model — an unpinned/floating action reference, introduced accidentally or via a later-compromised upstream dependency, that a human reviewer approves without noticing. It does not provide a hard boundary against a PR from someone who already has enough access to edit
.github/workflows/**/.github/actions/**and is specifically trying to evade the gate (e.g. by tampering with the gate's own job/script, since both are read from the same PR ref GitHub Actions checks out). That narrower threat is mitigated in practice by required human review of workflow-file changes, not by this tool. Six concrete residual findings — including that trust-boundary question, a path-traversal edge case in the local-reference exemption, a renamed-aggregator bypass, a false-positive on local reusable workflows, and compoundif:boolean expressions a regex can't fully evaluate — are recorded with architecture options in #506, deliberately not fixed in this PR to keep it bounded.Wiring
