Drizzle schema for projects, defects, push_subscriptions (C8); generated migration; a defects repository (createDefect / listRecentDefects); a programmatic migrator; and a db:verify script. section_id is a plain string referencing in-code board ids, no FK (ADR 0001). Verified against real Postgres: migration applies, a defect round-trips, /api/health reports db up.
