Personalization, visual search, dynamic pricing

Personalization (packages/commerce/src/personalization/, D1 customers, customer_sessions, behavior_events, abandoned_carts): behavior telemetry (view, add_to_cart, checkout_start, purchase) is captured fire-and-forget from the catalog/cart tools. recommend_products runs Vectorize similarity seeded from a product id or the thread’s recent behavior; identify_customer upserts a customer by email, links the session, and back-attaches the thread’s behavior events for cross-session continuity.

Cart recovery — the abandoned-cart cron (packages/commerce/src/personalization/abandoned-cart-job.ts) scans behavior_events for threads with purchase intent but no purchase, idle over an hour; it records abandoned_carts rows (deduped), emits cart_abandoned audit events + an orchestrator_abandoned_carts_detected counter, and dispatches to COMMERCE_RECOVERY_WEBHOOK when configured (SSRF-guarded; audit-only when unset).

Visual search (packages/commerce/src/visual/) — caption-then-embed: product images are captioned by a Workers AI vision model, the caption embedded into the same 768-dim BGE index; an uploaded query image runs the identical caption → embed → cosine path. Exposed as the search_by_image tool and POST /shop/visual-search.

Dynamic pricing (packages/commerce/src/pricing/, D1 pricing_rules, competitor_prices): rules have scope (catalog|category|product), kind (time|velocity|competitor), a signed adjustment_bps (negative = discount), and floor/ceiling clamps. Matching adjustments sum and clamp. Applied at catalog display and B2B quote pricing; cart items snapshot their price at add time so a rule change never silently reprices a cart.
