Core value: Reliable, persistent visibility into which services need updating — data never disappears, and the dashboard is the one place you trust to show the full picture. Current focus: Phase 03 — postgresql-support

Decisions

Decisions are logged in PROJECT.md Key Decisions table. Recent decisions affecting current work:

• Fix SQLite bugs before any other work — data trust is the #1 priority; bug-fix tests become the regression suite for the refactor
• Backend refactor must be behavior-neutral — all existing tests must pass before PostgreSQL is introduced
• No ORM or query builder — raw SQL per store implementation; 8 operations across 3 tables is too small to justify a dependency
• DATABASE_URL present activates PostgreSQL; absent falls back to SQLite with DB_PATH — no separate DB_DRIVER variable
• [Phase 01]: Use named-column UPSERT (ON CONFLICT DO UPDATE) to preserve tag_assignments child rows on re-insert
• [Phase 01]: Enable PRAGMA foreign_keys = ON in InitDB() before DDL to activate ON DELETE CASCADE for tag deletion
• [Phase 01-data-integrity]: Use MaxBytesReader + errors.As(*http.MaxBytesError) per-handler (not middleware) for request body size limiting — consistent with no-middleware architecture
• [Phase 01-data-integrity]: Oversized body tests need valid JSON prefix so decoder reads past 1MB limit; all-x bytes fail at byte 1 before MaxBytesReader triggers
• [Phase 02-backend-refactor]: Store interface with 9 methods is the persistence abstraction; SQLiteStore holds *sql.DB and sync.Mutex as struct fields (not package globals)
• [Phase 02-backend-refactor]: golang-migrate v4.19.1 database/sqlite sub-package confirmed to use modernc.org/sqlite (no CGO); single 0001 baseline migration uses CREATE TABLE IF NOT EXISTS for backward compatibility
• [Phase 02-backend-refactor]: Option B for test store access: internal helpers in export_test.go (TestUpsertEvent, TestGetUpdatesMap) instead of exported Store() accessor - keeps store field unexported
• [Phase 02-backend-refactor]: NewTestServer pattern: each test gets its own in-memory SQLite DB (RunMigrations + NewSQLiteStore + NewServer) - eliminates shared global state between tests
• [Phase 03-postgresql-support]: PostgresStore uses *sql.DB via pgx/v5/stdlib adapter with no mutex; TEXT timestamps match SQLiteStore scan logic
• [Phase 03-postgresql-support]: CreateTag uses RETURNING id in PostgresStore (pgx does not support LastInsertId); AssignTag uses ON CONFLICT DO UPDATE
• [Phase 03-postgresql-support]: DATABASE_URL presence-check activates PostgreSQL; absent falls back to SQLite — simpler UX than a separate DB_DRIVER var
• [Phase 03-postgresql-support]: postgres Docker service uses profiles: [postgres] with required: false depends_on — default compose up unchanged, SQLite only
• [Phase 03-postgresql-support]: UNIQUE constraint detection uses strings.ToLower for case-insensitive matching across SQLite (uppercase UNIQUE) and PostgreSQL (lowercase unique)

Pending Todos

None yet.

Blockers/Concerns

• Phase 3: Verify pgx/v5/stdlib import path against pkg.go.dev before writing PostgreSQL query strings
• Phase 3: Re-confirm golang-migrate v4.19.1 database/sqlite sub-package uses modernc.org/sqlite (not mattn/go-sqlite3) at implementation time
