Decomposer produced 9 stories under docs/work/2026-05-14-ci- security-and-supply-chain/, ordered to land the schema foundation first and the cross-referencing content (reviewer prompt, guide) last: 01 - trace schema extensions (socketRisk + lastRevalidated) 02 - Socket integration (skill + CI) 03 - Renovate adoption 04 - major-bump re-evaluation flow 05 - trace revalidation workflow 06 - CodeQL + audit signatures 07 - gitleaks pre-commit 08 - reviewer prompt update 09 - CI security guide + docs Also fixes a one-char status typo in the PRD frontmatter (\`appoved\` -> \`approved\`) that landed with the decompose run. Anchored by ADR-023 + the approved PRD at docs/work/prds/2026-05-14-ci-security-and-supply-chain.prd.md. Sequencing: depends on stories 01/02/04/06 of the in-flight library-evaluation epic landing first.

Goal
Add two baseline GitHub-native gates: (1) a pnpm audit signatures --audit-level=high step in ci.yml's validate job, and (2) a .github/workflows/codeql.yml workflow running javascript-typescript static analysis on push/PR/weekly schedule.
Why
pnpm audit signatures catches tampered package signatures before they reach production — a post-install script from a compromised maintainer account would fail this check. CodeQL's javascript-typescript analysis catches common vulnerability patterns (XSS, injection, prototype pollution) that are invisible to dependency-scanning tools. Both are zero-cost on public repos and the GitHub Free plan; CodeQL's template includes a clear no-op on plans that don't support it.
Done when
ci.yml'svalidatejob includes apnpm audit signatures --audit-level=highstep. The step fails the job onhighorcriticalseverity signature failures..github/workflows/codeql.ymlexists; triggers:push: branches: [main],pull_request, andschedule: - cron: "0 2 * * 3"(Wednesday 02:00 UTC, staggered from the trace-revalidation cron); language:javascript-typescript; uses default queries. Includes a comment noting that CodeQL on private repos requires GitHub Advanced Security (consumer-toggleable per PRD constraint).pnpm typecheck && pnpm lint && pnpm test && pnpm conformance && pnpm fallow:audit && pnpm coverage:diffall pass (no executable code change; CI config only).
In scope
.github/workflows/ci.yml— one newpnpm audit signaturesstep invalidatejob..github/workflows/codeql.yml— new workflow file.
Out of scope
- Configuring GitHub branch protection to require CodeQL as a status check — consumer-facing instruction deferred to Story 09's guide.
- OSSF Scorecard — explicitly out of PRD scope.
- StepSecurity Harden Runner — explicitly out of PRD scope.
Tasks
- Add
pnpm audit signatures --audit-level=highas a step inci.yml'svalidatejob; one commit, all gates pass. - Create
.github/workflows/codeql.yml(language:javascript-typescript; triggers: push to main, pull_request, weekly schedule Wednesday 02:00 UTC; default queries; consumer note about GitHub Advanced Security requirement for private repos); one commit, all gates pass.
