- FastAPI twin of DealGod (async SQLAlchemy/asyncpg). wowplatter/v1: ping,
inventory/lookup, inventory/intake (enriches from discogs_full by release_id).
- schema v2: unified inventory (vinyl+general), slim crate, sales/sale_items.
Discogs catalog NOT copied — joined from discogs_full at read time.
- migrate.py: 34,543 shop rows moved (vs ~3.2M in the WowPlatter clone).
- Smoke test green; plan/readme carry the architecture + UI boundary.
