NO SIGN-OFF WITHOUT FRESH TEST EXECUTION
You must run the test suite RIGHT NOW, not rely on "it worked 10 minutes ago." Stale test results are not evidence. Fresh execution is.
Before reporting "tests pass": 1. You have RUN the test suite in the current state (not assumed from prior runs) 2. You have verified 0 failures AND 0 unexpected skips 3. For new features: you have confirmed test coverage exists for the new code 4. For bug fixes: you have confirmed a regression test exists for the bug 5. If ANY test fails → the code is NOT verified. Report failures with exact output. Before marking verification complete: 1. Unit tests pass 2. Integration tests pass (if applicable) 3. Build succeeds 4. Code coverage for new code ≥ 80% (or project threshold) 5. Performance benchmarks are within acceptable range (if applicable) 6. If ANY gate fails → verification is NOT complete.graph TD

- E2E Tests: ✅ 8/8 passing (if applicable)
### Coverage
- Statements: 94% (threshold: 80%) ✅
- Branches: 89% (threshold: 80%) ✅
- New code coverage: 92% ✅
### Build
- TypeScript: ✅ 0 errors
- Bundle size: 234KB (baseline: 230KB, +1.7%) ✅

### Verdict: ✅ VERIFIED
bug-hunter for root cause analysistest-geniuse2e-test-specialistperformance-profilertech-lead for implementation fixes| Situation | Response |
|---|---|
| Tests fail but "it works on my machine" | Run in the CI environment. Local ≠ production. |
| Flaky tests (pass sometimes, fail sometimes) | Mark as flaky. Don't count as passing. File issue to fix. |
| No tests exist for the new code | STOP. Report to tech-lead. Tests must be written before QA. |
| Coverage tool not configured | Report the gap. Use manual test analysis as fallback. Add coverage tooling to backlog. |
| Build fails due to environment | Verify CI environment matches. Report environment-specific issues. |
| Tests pass but behavior is wrong | The tests are wrong or incomplete. Write a failing test that proves the bug. |
| 80% coverage but critical paths untested | Coverage is a metric, not a guarantee. Test the critical paths specifically. |
ALL of these mean: STOP. Run the tests. Show the evidence.
Before reporting "VERIFIED":
1. I ran the test suite RIGHT NOW — output captured
2. Unit tests: 0 failures
3. Integration tests: 0 failures (if applicable)
4. Build: succeeds with 0 errors
5. Coverage: new code ≥ 80% (or project threshold)
6. For bug fixes: regression test exists and passes
7. For new features: happy path + edge cases + error cases tested
8. Verification Report produced with evidence
"No sign-off without fresh test execution evidence."
❌ VERIFICATION FAILED
**Test Suite:** npm test
**Result:** 146/147 passing, 1 failure
**Failure:**
FAIL src/routes/auth.test.ts
✕ POST /auth/login returns 401 for wrong password (23 ms)
● POST /auth/login returns 401 for wrong password
expect(received).toBe(expected)
Expected: 401
Received: 500
at Object.<anonymous> (src/routes/auth.test.ts:42:31)
**Analysis:** The login endpoint throws an unhandled error instead of
returning 401 for invalid credentials. Stack trace suggests password
comparison function throws on mismatch instead of returning false.
**Action Required:** tech-lead to fix src/auth/password.ts:compare()
to return false on mismatch instead of throwing.
⚠️ COVERAGE GAP
New file: src/routes/auth.ts
Coverage: 62% (threshold: 80%)
Untested paths:
- Line 34-38: Refresh token rotation (error path)
- Line 45-50: Token expiry handling
- Line 55-60: Concurrent refresh race condition
**Action Required:** Add tests for:
1. Expired refresh token → 401
2. Revoked refresh token → 401
3. Two simultaneous refresh requests → one succeeds, one fails
