# Verification Report

**Change**: mysql-review-persistence  
**Version**: N/A  
**Mode**: Strict TDD  
**Artifact Store**: both (Engram + OpenSpec)

### Completeness
| Metric | Value |
|--------|-------|
| Tasks total | 16 |
| Tasks complete | 16 |
| Tasks incomplete | 0 |
| Required OpenSpec artifacts read | proposal, spec, design, tasks |
| Required Engram SDD artifacts read | proposal, spec, design, tasks, apply-progress |

Exit: 0
tsc -p tsconfig.json
```

**Typecheck**: ✅ Passed
```text
Command: npm run typecheck
Exit: 0
tsc -p tsconfig.json --noEmit
```

**Tests**: ✅ 44 passed / ❌ 0 failed / ⚠️ 0 skipped
```text
Command: npm test
Exit: 0
Test Files  11 passed (11)

### TDD Compliance
| Check | Result | Details |
|-------|--------|---------|
| TDD Evidence reported | ✅ | Found in Engram apply-progress artifact. |
| All tasks have tests | ✅ | 16/16 tasks have direct test or verification evidence; verification-only task 4.3 has full-suite evidence. |
| RED confirmed (tests exist) | ✅ | Listed test files exist and were inspected. |
| GREEN confirmed (tests pass) | ✅ | All listed test files passed under `npm test`. |
| Triangulation adequate | ✅ | Config, pool, mapper, repository, route, app wiring, and env example have multiple behavioral cases where applicable. |
| Safety Net for modified files | ✅ | Apply-progress reports safety-net runs for modified files; current full suite passes. |

**TDD Compliance**: 6/6 checks passed

### Test Layer Distribution
| Layer | Tests | Files | Tools |
|-------|-------|-------|-------|
| Unit | 11 | 5 | Vitest |
| Integration | 12 | 2 | Vitest + Express/fetch |
| E2E | 0 | 0 | Not configured |
| **Total related** | **23** | **7** | |

### Changed File Coverage
Coverage analysis skipped — no coverage tool detected.

### Assertion Quality
**Assertion quality**: ✅ All related assertions verify real behavior. One `toBeDefined()` assertion exists in `src/server/app.test.ts`, but it is combined with wiring/value assertions in the same test and is not standalone type-only coverage.

### Quality Metrics
**Linter**: ➖ Not available  
**Type Checker**: ✅ No errors

### Spec Compliance Matrix
| Requirement | Scenario | Test | Result |
|-------------|----------|------|--------|
| Validate MySQL config | Missing DB config | `src/config.test.ts > fails fast when a required DB environment variable is missing` | ✅ COMPLIANT |
| Validate MySQL config | Invalid DB port | `src/config.test.ts > fails fast when DB_PORT is not a valid port number` | ✅ COMPLIANT |
| Store reviews with idempotent upsert | First delivery inserts a row | `src/repositories/mysqlReviewRepository.test.ts > executes a parameterized reviews upsert with ordered review values` | ✅ COMPLIANT |
| Store reviews with idempotent upsert | Duplicate delivery updates the same row | `src/repositories/mysqlReviewRepository.test.ts > executes a parameterized reviews upsert with ordered review values` | ✅ COMPLIANT |
| Map ActivePiece fields to review columns | Rating is converted from enum label | `src/services/reviewPersistenceService.test.ts > maps ActivePiece review fields and converts puntuacion=FIVE to rating 5` and route enum tests | ✅ COMPLIANT |
| Map ActivePiece fields to review columns | Missing fields remain null/default | `src/services/reviewPersistenceService.test.ts > keeps missing nombre as nullable authorName and never invents authorUrl from name`; repository SQL omits optional/default columns | ✅ COMPLIANT |
| Handle author URL storage safely | No safe mapping exists | `src/services/reviewPersistenceService.test.ts > keeps missing nombre as nullable authorName and never invents authorUrl from name` | ✅ COMPLIANT |
| Preserve response generation and report failures | Persistence succeeds | `src/routes/reviewRoute.test.ts > persists the review before generating the unchanged Gemini response payload` | ✅ COMPLIANT |
| Preserve response generation and report failures | Persistence fails | `src/routes/reviewRoute.test.ts > fails safely when persistence fails without calling Gemini or logging secret values` | ✅ COMPLIANT |

**Compliance summary**: 9/9 scenarios compliant

### Correctness (Static Evidence)
| Requirement | Status | Notes |
|------------|--------|-------|
| Env-only MySQL config | ✅ Implemented | `src/config.ts` requires `DB_HOST`, `DB_USER`, `DB_PASSWORD`, `DB_NAME`, `DB_PORT`; `.env.example` uses placeholders only. |
| MySQL pool | ✅ Implemented | `src/database/mysqlPool.ts` creates a `mysql2/promise` pool from validated config. |
| Repository upsert | ✅ Implemented | `src/repositories/mysqlReviewRepository.ts` uses placeholders and `ON DUPLICATE KEY UPDATE`. |
| Mapper/service | ✅ Implemented | `src/services/reviewPersistenceService.ts` maps `id`, `nombre`, `comentario`, `puntuacion`, `source`, and null `authorUrl`. |
| Route behavior | ✅ Implemented | `src/routes/reviewRoute.ts` persists before Gemini, preserves success payload, and returns safe 502 on persistence failure. |
| App wiring | ✅ Implemented | `src/server/app.ts` wires pool → repository → persistence service → review router. |

### Coherence (Design)
| Decision | Followed? | Notes |
|----------|-----------|-------|
| Use `mysql2/promise` pool | ✅ Yes | Dependency and pool factory are present. |
| Repository + persistence service | ✅ Yes | SQL is isolated in repository; mapping/orchestration is in service. |
| Persist before Gemini | ✅ Yes | Route awaits persistence before calling `generateResponse`; call order is tested. |
| Leave `author_url` null | ✅ Yes | Mapper always sets `authorUrl: null`; tested. |

### Issues Found
**CRITICAL**: None  
**WARNING**: None  
**SUGGESTION**: Consider adding a future MySQL-backed integration/E2E test with a disposable database if schema drift becomes a recurring risk; current OpenSpec explicitly did not require this.

### Verdict
PASS

Strict TDD verification passed: all tasks are complete, all required commands passed, all spec scenarios have passing covering tests, design decisions are followed, and DB credentials are env-only/placeholders.
