Ametller Origen v0.4.0

Backtested smart baskets: replaces cadence ranking with the validated 10/30/120-day repeat-purchase model, cleans and merges online/offline history, excludes the current cart before and after catalog resolution, and keeps novel-product discovery separate. Protein rotation is available only as an explicit experimental mode. The MCP App still requires visible approval before cart additions and exposes no checkout or payment tool. Adds the one-command checkout-free gate: npm run verify.
