18 TDD-ordered tasks covering the four migrations (149-152), two store interfaces with in-memory fakes, seven collection handlers + ten playlist handlers, pgx-backed concrete stores, service wiring, route registration, and the full-verification gauntlet. Total ~3000 lines; each task is bite-sized (2-5 minute steps) and produces a green commit. Each spec §8 test maps to a task. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
