Clean-Slate Re-Inventory

Replaces the original Square catalog import (~1,700 items, many stale). Medusa starts clean, populated via physical re-inventory of the store.

Workflow

Fork Agilo’s Medusa POS Starter (Expo + React Native, already has barcode scanning + Medusa API integration) and adapt into ISBN scanner app
Walk the store, scan each book’s ISBN
App queries Ingram Web Service (or Open Library) by ISBN for metadata (title, author, publisher, cover image, description, price, format)
Product created in Medusa as draft
Staff reviews and publishes
Non-ISBN items (dice, minis, totes, stickers) entered manually

Medusa catalog starts clean — only what’s physically on shelves
This IS the Ingram enrichment tool from the spec, just used for initial inventory instead of ongoing expansion — build it once, use it forever
Square catalog stays as-is for POS — no cleanup required upfront
The sync layer only maps ISBNs that exist in both systems, which after re-inventory is exactly the active physical inventory
Everything in Square without a Medusa counterpart is implicitly archivable

Brief 1.3 changes from “Square→Medusa migration script” to “ISBN scanner app + Ingram/OpenLibrary enrichment tool”
Phase 3 (Square POS sync) gets simpler — smaller, cleaner mapping set
Post-MVP Ingram integration is partially built from day one
