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's parseDocument (YAML 1.2 core schema) against every .github/workflows/*.yml and .github/actions/**/action.yml file, with aliases (&anchor/*alias) resolved at every container and scalar boundary (job values, permissions, needs, if, steps, uses):

  1. Top-level permissions must be exactly {contents: read} or the scalar read-all.
  2. Job-level write-scope permissions are restricted to an explicit per-workflow, per-job allowlist; scalar write-all is rejected the same as an unallowlisted mapping form.
  3. 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.
  4. Every remote uses: reference (step-level, job-level reusable-workflow, and Docker runs.image) must pin a 40-hex-char SHA or an immutable @sha256 digest, 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 path listActionFiles scans) and recurse to any depth, rejecting any symlink found along the way.
  5. The ✅ CI Success aggregator's needs: list is checked against actual gating jobs; if its if: condition overrides GitHub's default success-gating (always()/failure()/cancelled(), aliased or not), its run script must explicitly check every gating job's .result.
  6. A publishing boundary: only an explicit allowlist may declare contents: write, and an allowlisted job's if: condition must still verifiably restrict it to a tag push — loosening that condition no longer silently passes by job name alone.
  7. The gate itself runs from a new workflow-policy CI job with no dependencies, before any other job invokes the governed ./.github/actions/setup composite, 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 compound if: 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

  • pnpm run workflow-policy:check (new script, invoked via node directly — not pnpm run — from CI to avoid an unrelated pnpm install-fingerprint conflict)
  • New workflow-policy CI job (ci.yml), required via security's needs: and the ci-success aggregator
  • Local pre-push admission (ci:prepush) runs it when .github/workflows/**/.github/actions/** change

Fixed along the way

The gate caught one genuine pre-existing inconsistency: the signatures job's checkout step was missing the trailing SHA-pin comment every other checkout call has.

Test plan

  • pnpm run lint — clean
  • pnpm exec tsgo --project tsconfig.tsgo.json --noEmit --checkers 4 — clean (exact CI command)
  • pnpm exec vitest run tests/unit/tooling/workflowPolicyCheck.test.ts tests/unit/workflowPolicy.test.ts tests/unit/tooling/strykerWorkflowPolicy.test.ts — 84/84 pass
  • pnpm run workflow-policy:check — passes against the repo's real current workflow/action files, including the new workflow-policy job's own tag-gate/aggregator-sync requirements
  • pnpm run ci:prepush — full local admission green
  • git diff --check — clean
  • All commits SSH-signed (git log --show-signature)
  • Real GitHub CI: ✅ CI Success and every required + advisory job green on the final head, including the new 📜 Workflow Policy Gate job

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).

Reviewer's Guide

This PR introduces a YAML-parser-based GitHub Actions workflow authority that enforces permissions, write-scope and publishing boundaries, dependency-graph integrity, aggregator correctness, and immutable remote action pins. It is wired into CI and conditional pre-push admission, backed by focused unit tests, and includes the workflow annotation fix required for the current repository to pass.

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 scalar read-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.

📝 Walkthrough

Walkthrough

Adds a workflow-policy validator for GitHub Actions workflows and composite actions. It checks YAML permissions, dependencies, action pins, aggregator jobs, and publishing boundaries. CI and prepush admission invoke the validator, with expanded tests, documentation, and README metrics.

Changes

Workflow policy validation

Layer / File(s)Summary
Policy engine and validation
scripts/workflow-policy-check.mjs, scripts/workflow-policy-check.d.mts
Adds recursive composite-action discovery, YAML alias and line tracking, permission and dependency checks, action-pin validation, aggregator result enforcement, publishing checks, declarations, and failure reporting.
Policy validation tests
tests/unit/tooling/workflowPolicyCheck.test.ts, tests/unit/workflowPolicy.test.ts
Adds tests for workflow and composite-action policies, YAML aliases and errors, dependency graphs, action and Docker pins, aggregators, publishing boundaries, discovery, symlinks, failure aggregation, and the ci-success dependency.
CI and prepush integration
scripts/ci-prepush-check-registry.mjs, scripts/ci-prepush-lowend.mjs, package.json, .github/workflows/ci.yml
Registers workflow and composite-action files for admission checks, adds the workflow-policy:check script and yaml dependency, and runs the policy gate before governed CI jobs. The ci-success job requires and reports the gate result.
CI policy documentation
AGENTS.md, docs/CI.md
Documents the workflow-policy gate, isolated setup, CI job graph, required dependencies, and validation scope.
Repository test metrics
README.md
Updates reported test totals to 7,076+ tests across 579 files.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk:🔵 Low · up to a05e1

The new workflow validation can incorrectly reject valid workflows that use YAML aliases for advisory jobs or result checks, causing avoidable CI or local pre-push failures. The PR is mergeable with explicit owner awareness and follow-up to resolve these aliases.

qnbs added 2 commits August 26, 2026 04:56
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).

109-114: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value

Split the two readdirSync shapes in CheckAllWorkflowsDependencies.

ListWorkflowFilesDependencies.readdirSync is (dir: string) => string[]. ListActionFilesDependencies.readdirSync is (dir: string, options: { withFileTypes: true }) => DirEntryLike[]. The intersection turns readdirSync into an overloaded member, so a consumer cannot supply one function that satisfies both signatures. Callers must then inject listWorkflowFiles and listActionFiles instead, which the test file already does.

Consider giving the action-file discovery dependency a distinct key, or widen the shared signature to one overload set that both discovery functions accept.

…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).

read from the real ci.yml. 3e0c110 added the workflow-policy
prerequisite job to that array (correctly — required by S4's own

Comment threadscripts/workflow-policy-check.mjs
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).
