Verified 2026-05-16, story 15-1. +**CI coverage gating — `jest --coverage` wired into CI with 40% threshold floor on `src/lib/` + `src/hooks/`:** post-Epic-15.6, the SIXTH and final Epic 15 (Test Coverage & QA Infrastructure) story closes the Epic 15.6 deliverable at [`shippable-roadmap.md` line 299](_bmad-output/planning-artifacts/shippable-roadmap.md) ("CI gating — Jest threshold ≥ 40% on `src/lib/` and `src/hooks/`; fail PR on regression."). Pre-15-6 the repo had **2167+ Jest tests across libs / hooks / components / prompts / schemas** (the Story 12-10 audit-refresh footnote corrected the pre-15-X audit's stale "3-5% coverage" framing) but **no CI coverage gate** — a PR that removed tests or added substantial untested code merged silently. Story 15-6 lands the gate. **(1) [`jest.config.js`](jest.config.js)** extended with three additive blocks: `collectCoverageFrom: ["src/lib/**/*.{ts,tsx}", "src/hooks/**/*.{ts,tsx}", "!**/__tests__/**", "!**/*.d.ts"]` (scope matches spec deliverable), `coverageThreshold: { global: { statements: 40, branches: 40, functions: 40, lines: 40 } }` (40% floor per spec literal — the audit's `≥ 40%` mandate is the starting bar, not the aspirational ceiling), and `coverageReporters: ["text-summary", "lcov"]` (text-summary for CI log readability; lcov for future Codecov / Coveralls integration without re-running). **(2) [`package.json`](package.json)** gains a new `test:coverage` script wired to `jest --coverage` (placed adjacent to `test:watch` for adjacency). **(3) [`.github/workflows/ci.yml`](.github/workflows/ci.yml)** gains a new step `Tests with coverage threshold` running `npm run test:coverage` IMMEDIATELY AFTER the existing `Tests` step (Q1 RECOMMENDED — keep both for separation of concerns: fast green-light feedback before the slower instrumented run). The new step does NOT carry `continue-on-error: true` (Story 12-10 R1-H2 silent-disable defense) and does NOT carry an `if:` key (defense-in-depth against accidental gate-skipping). **(4) Measured coverage baseline at gate introduction (2026-05-17)**: Statements **53.42%** (2325/4352) / Branches **55.80%** (1417/2539) / Functions **51.49%** (362/703) / Lines **54.12%** (2126/3928). The 40% spec floor leaves **≈11 points of headroom against the lowest metric (Functions)** — sufficient for a future PR to add untested code without breaking CI immediately, while a sustained regression (e.g., a deleted test file dropping Functions below 40%) trips the gate. Q2 RECOMMENDED was "measured floor minus 3%" but the 40% spec literal already leaves comfortable headroom, so the spec floor was used as-is. A future PR can ratchet to 50% once Functions coverage grows (filed as `15-6-followup-coverage-ratchet-cadence`). **(5) NEW drift detector** at [`src/lib/__tests__/ci-coverage-gate-source-drift.test.ts`](src/lib/__tests__/ci-coverage-gate-source-drift.test.ts) (6 cases via Story 12-2 P12 source-string drift pattern + Story 13-2 P11 paired POSITIVE+NEGATIVE pin discipline + Story 12-10 R1-M1 indexOf-ordering anchor + Story 12-10 R1-H2 step-block-scoped negative guard): (a) `coverageThreshold` whole-block regex with 40 floor on all 4 metrics (single-regex pin catches partial-drop e.g., dropping `branches`), (b) `collectCoverageFrom` 4-entry per-key pins (`src/lib/**/*.{ts,tsx}` + `src/hooks/**/*.{ts,tsx}` + `!**/__tests__/**` + `!**/*.d.ts`), (c) `package.json` `test:coverage` script value === `"jest --coverage"` exactly, (d) `ci.yml` step name + `npm run test:coverage` run command, (e) `coverageStepIdx > testsStepIdx` ordering (Story 12-10 R1-M1 anchor-on-exact-step-name pattern), (f) NEGATIVE within the coverage step's block: no `continue-on-error: true` and no `if:` (Story 12-10 R1-H2 lesson — scope the silent-disable check to the step block, not the file). **(6) `coverage/` directory** added to both `.gitignore` and `.prettierignore` so the generated lcov + HTML report don't get tracked or reformatted. **3 operator decisions resolved per Recommended**: Q1 keep both `Tests` + `Tests with coverage threshold` steps (fast feedback + slow gate); Q2 use spec-literal 40% (vs measured-floor-minus-3% — spec floor already leaves ≈11 points of headroom); Q3 defer Codecov / Coveralls integration to operator-action follow-up `15-6-followup-codecov-integration` (needs Codecov account setup). **Closes Epic 15.6 deliverable architecturally** + closes the audit-mandated "CI must be a real gate, not green-light theater" framing (Story 12-10's `--audit-level=high` audit gate + Story 15-6's `--coverage` threshold gate together form the two-layer CI quality bar — vulns + tests). **Cross-story invariants preserved by construction:** Story 9-3 Sentry allowlist zero-diff (no telemetry surface — coverage is a build-time metric) / Story 9-4 stored-prompt-injection N/A / Story 11-X / 12-X / 13-X / 14-X / 15-1 through 15-5 all orthogonal (the coverage gate runs the existing suite + measures it; doesn't modify any source surface). **0 source-module modifications** beyond the 5 spec-allowed surfaces (`jest.config.js`, `package.json`, `.github/workflows/ci.yml`, `.gitignore`, `.prettierignore`) + 1 new drift test + 1 spec/sprint-status/CLAUDE.md trio. **Regression-tested with +6 net Jest cases** (2159 → 2165; matches spec target +5–7 squarely in range).

The load-bearing one (BH-2/EH-4 per-directory thresholds) REVEALED a real coverage gap that the global average had been masking. HIGH: - BH-2 / EH-4 (load-bearing): added per-directory coverageThreshold scopes ('./src/lib/' + './src/hooks/') so the spec deliverable's CONJUNCTION ("≥ 40% on src/lib AND src/hooks") is enforced, not the average. Per-directory floors immediately revealed src/hooks/ is at 23.02% statements / 27.12% branches / 25.92% functions / 23.36% lines — well below 40%. The global metric (53.42%) was averaging this against src/lib/ which is much higher. Per spec AC-E ("if below 40% on ANY metric, lower threshold to floor-minus-3% of actual"), calibrated src/hooks/ floors to 20/24/22/20. Global stays at 40 (belt-and-suspenders); src/lib/ stays at 40 (above measured). Filed 15-6-followup-lift-hooks-coverage-to-40 to raise the per-dir floor as future stories add hook tests. - BH-1 ordering regex anchor: pre-R1 'indexOf("- name: Tests\\n")' was fragile to trailing-whitespace/CRLF drift. Anchored via '/^\\s{6}- name:\\s*Tests\\s*$/m' (PR #115 EH-4 lesson reused). - BH-3 tail-slice safer fallback: pre-R1 if coverage step ever moved to be the last step, the silent-disable negative guard would sweep entire file + false-positive on Expo Doctor's legitimate 'continue-on-error: true'. Bounded slice to 1500 chars. - EH-1 block-comment-wrap bypass defense: drift detector deliberately doesn't comment-strip jest.config.js (glob '/**' sequences eat the block-comment regex). New Case 0 verifies the 200 chars preceding 'coverageThreshold:' don't contain an unmatched opening block-comment marker. MED: - BH-5 gitignore anchor: 'coverage/' (no leading /) matches at any depth. Changed to '/coverage/' so a future sub-dir like 'docs/insurance-coverage/' isn't silently dropped. - BH-8 / EH-2 upload-artifact: AC #5 marked upload as 'recommended' but wasn't implemented. Added 'actions/upload-artifact@v4' with 'if: always()' so gate- failure PRs still upload coverage for triage. 14-day retention. - EH-10 sibling-test exclude: extended collectCoverageFrom with '!**/*.test.{ts,tsx}' + '!**/*.spec.{ts,tsx}' so a future contributor adopting sibling-test convention can't artificially inflate coverage by running test files end-to-end. LOW: - EH-9 fractional tolerance: drift detector regex now tolerates '40' OR '40.0' (Prettier reformat resilience). Per-directory scopes use general '\\d+(?:\\.\\d+)?' since calibrated floors differ from 40. Documented (no code change): BH-4/EH-7 CI cost trade-off (added CI step comment), BH-6 scope gap + follow-up filed, BH-7/EH-5 forceExit + coverage interaction, EH-8 float-vs-rounded gotcha.
