+# Phase 16: CI Dependency Audit, Security Checks & Image Hygiene — Verification Report
+
+**Phase Goal:** Extend Gitea CI with outdated-dependency reporting + vulnerability audit + a baseline of additional security checks, and enforce the dev/prod image boundary so no dev-bypass, secret, or family data ships in published images.
+**Verified:** 2026-06-13T12:56:26Z
+**Status:** passed
+**Re-verification:** No — initial verification
+
+## Goal Achievement
+
+### Observable Truths
+
+| # | Truth | Status | Evidence |
+|---|-------|--------|----------|
+| 1 | A production image with DEV_AUTH_BYPASS=true refuses to boot (process exits non-zero) | VERIFIED | `assertNotDevBypassInProduction()` in `bootGuards.ts` calls `process.exit(1)` when `NODE_ENV==='production' && DEV_AUTH_BYPASS==='true'`; 3/3 unit tests pass |
+| 2 | The production Docker stage bakes NODE_ENV=production so the devBypass hard guard is engaged | VERIFIED | `ENV NODE_ENV=production` at line 45 of `apps/api/Dockerfile`, inside `FROM base AS production` stage only |
+| 3 | The boot guard is a unit-tested exported function, called first in isMainModule() | VERIFIED | `bootGuards.ts` exports `assertNotDevBypassInProduction`; called at `index.ts:116` as the first statement inside `if (isMainModule()) {`, before VAPID config (line 121), workers (line 141), and serve (line 149) |
+| 4 | The audit wrapper blocks unwaived High+Critical advisories; esbuild GHSA waived with expiry | VERIFIED | `check-audit.mjs` exports `selectBlocking`/`partitionAdvisories`/`isWaived`; no `--audit-level` flag; esbuild `GHSA-gv7w-rqvm-qjhr` waived in `audit-allowlist.json` with reviewer, reason, and future expiry `2026-09-01`; 9/9 unit tests pass (including expiry + fail-closed on malformed date) |
+| 5 | The outdated wrapper is advisory-only (always exits 0), tiered, and pin-aware | VERIFIED | `check-outdated.mjs` unconditionally calls `process.exit(0)` at line 189; no reachable `process.exit(1)`; four tiers (OUTDATED-WITH-ADVISORY / MAJOR-BEHIND-INTENTIONAL / MAJOR-BEHIND-UNPINNED / ROUTINE-DRIFT); reads `outdated-pins.json` with four pin reasons (eslint, @eslint/js, zod, @types/node) |
+| 6 | eslint-plugin-security runs as blocking errors in pnpm lint, baseline is green | VERIFIED | `eslint-plugin-security@3.0.1` in root devDependencies; folded into `eslint.config.js` section 5 before `prettierConfig`; `detect-object-injection` disabled globally with inline justification comment; `pnpm lint` exits 0 with `--max-warnings 0`; `pnpm typecheck` passes |
+| 7 | A gitleaks config with useDefault + fixture allowlists exists; clean baseline committed | VERIFIED | `.gitleaks.toml` has `[extend] useDefault = true` and 4 `[[allowlists]]` blocks (VAPID fixture, .env.example, .env.spike, crypto test); `scripts/gitleaks-baseline.json` is valid JSON `[]` (empty — no pre-existing findings); `.dockerignore` covers all 7 forbidden patterns and does NOT exclude `apps/api/src` |
+| 8 | security job (gitleaks always; audit/outdated code-gated) wired into gate as strict success | VERIFIED | `ci.yml` has `security:` job with `needs: [changes]`, `if: pull_request`; checkout has `fetch-depth: 0`; gitleaks steps have no `if:`; audit/outdated steps have `if: needs.changes.outputs.code == 'true'`; gate `needs:` includes `security`; gate script checks `needs.security.result != 'success'` as an individual non-skippable check (not in the success-or-skipped loop) |
+
+**Score:** 8/8 truths verified
+
+### Required Artifacts
+

+| `.gitea/workflows/publish.yml` | Static assertion + boot-smoke between build and push | VERIFIED | Step order: Build → static assertions → boot-smoke → Push |

+
+### Probe Execution
+
+Step 7c skipped — no probe scripts declared or expected for this phase (CI workflow verification; no `probe-*.sh` files present).
+
+### Requirements Coverage
+
+Phase 16 requirement IDs are defined in PLAN frontmatter and ROADMAP.md; they do not appear in `REQUIREMENTS.md` (which tracks only v1.1 functional requirements up to CI-01/CI-02). This is expected — REQUIREMENTS.md ends its traceability table at CI-02 and notes that CI, TEST, ADMIN, SETUP categories are tracked there. The Phase 16 operational/security requirement IDs (SEC-*, DEP-*, IMG-*, CI-03) are roadmap-internal tracking identifiers, not v1.1 product requirements.
+
+| REQ-ID | Plan | What was verified | Status |
+|--------|------|-------------------|--------|
+| IMG-01 | 16-01 | `bootGuards.ts` exported guard; `index.ts` wiring as first call in isMainModule; Dockerfile `ENV NODE_ENV=production` in production stage only | SATISFIED |
+| DEP-01 | 16-02 | `check-audit.mjs` blocks unwaived High+Critical; `audit-allowlist.json` with esbuild GHSA waiver pre-seeded; time-boxed expiry enforced | SATISFIED |
+| DEP-02 | 16-02 | `check-outdated.mjs` always exits 0; four tiers including intentional-pin; `outdated-pins.json` with 4 reasons | SATISFIED |
+| SEC-02 | 16-03 | `eslint-plugin-security@3.0.1` in root devDeps; folded into flat config before prettierConfig; `pnpm lint` exits 0 | SATISFIED |
+| SEC-01 | 16-04 | `.gitleaks.toml` with `useDefault=true` + fixture/env allowlists; `gitleaks-baseline.json` = `[]`; human checkpoint completed (baseline clean) | SATISFIED |
+| IMG-02 | 16-04 | `.dockerignore` covers all 7 required forbidden patterns; does NOT exclude `apps/api/src` | SATISFIED |
+| CI-03 | 16-05 | `security` job in ci.yml; gitleaks always-runs; audit/outdated code-gated; gate wires security via individual strict success check | SATISFIED |
+| IMG-03 | 16-06 | publish.yml: Build → static assertions (grep .dockerignore + `--target production`) → boot-smoke (assert non-zero exit + guard message) → Push | SATISFIED |
+
+### Anti-Patterns Found
+
+None. Scan of all 15 phase-16-modified files found no TBD/FIXME/XXX markers, no placeholder returns, no blanket `/* eslint-disable */` headers, no hardcoded empty data structures in rendering paths.
+
+Notable good patterns observed:
+- `detect-object-injection` disabled globally has inline justification comment (not silent `off`)
+- Audit wrapper expiry check fails **closed** on unparseable date strings (malformed → not waived)
+- Boot-smoke matches guard output text as belt-and-suspenders (non-zero exit alone is insufficient)
+
+### Human Verification Required
+
+Two items are structurally verified (YAML + logic) but require a live CI run to observe the end-to-end behavior. Per phase 16 RESEARCH.md and the verifier instruction notes, this is an expected/accepted constraint — the Gitea runner is not reachable locally, and a code-review + auto-fix loop was already completed.
+
+1. **Gitleaks PR diff scan blocks a real secret**
+   - **Test:** Open a PR that introduces a dummy secret string matching a gitleaks default rule (e.g. a fake `GITHUB_TOKEN=ghp_...` pattern in a test file not covered by allowlists)
+   - **Expected:** The `security` job fails; the `gate` job fails; the PR is blocked from merging
+   - **Why human:** Cannot drive the Gitea CI runner locally
+
+2. **Boot-smoke PASS on a freshly-built production image**
+   - **Test:** Merge a commit to `main`; observe the `publish` workflow run; verify the "Image hygiene — boot-smoke" step logs `PASS: Production image refused to start with DEV_AUTH_BYPASS=true`
+   - **Expected:** Step passes; `Push image` runs; image is published
+   - **Why human:** Cannot build and run the Docker image in this environment (no Docker daemon); boot-smoke requires the actual built image artifact
+
+---
+
+## Gaps Summary
+
+No gaps. All 8 observable truths are verified against the codebase, all 16 required artifacts exist and are substantive, all key links are wired. Behavioral spot-checks pass (9/9 unit tests, lint, typecheck, structural YAML parsing). Two human verification items remain for live CI observation, which is the expected end-state per the phase boundary (no Docker daemon, no Gitea runner locally).
