Today's Plan

  • FRE-4471: DarkWatch MVP — full scaffold and implementation

Timeline

  • 12:10 — Created implementation plan for 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
