## Today's Plan

- [x] FRE-4471: DarkWatch MVP — full scaffold and implementation

## Timeline

- **12:10** — Created implementation plan for [FRE-4471](/FRE/issues/FRE-4471) and uploaded to issue
- **13:00** — Scaffolded Turborepo monorepo: packages/api, packages/db, packages/types, packages/jobs, services/darkwatch
- **13:22** — Prisma schema with 5 models (User, WatchListItem, Exposure, Alert, ScanJob), migration applied
- **13:30** — Implemented WatchListService (CRUD, normalization, dedup, tier limits)
- **13:35** — Implemented HIBPService (API integration, severity scoring)
- **13:38** — Implemented MatchingEngine (exact-match, content hash dedup)
- **13:40** — Implemented AlertPipeline (24h dedup window, email notifications)
- **13:42** — Implemented ScanService (orchestrates full scan flow)
- **13:45** — Built Fastify API routes for watchlist, exposures, alerts, scan
- **13:48** — Set up BullMQ job workers for async processing
- **13:50** — Wrote 15 unit tests, all passing
- **14:00** — Committed, posted progress, marked FRE-4471 as `in_review`

## Key Decisions

- Used Turborepo monorepo with workspace packages
- String-based enums (const assertions) to match Prisma generated types
- SHA-256 content hash for exposure deduplication
- 24-hour dedup window for alerts via NodeCache + DB check
