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 02 — backend-refactor

Accumulated Context

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

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
