Replace product weight and repurchase intent fields with per-package remaining levels and inventory-first restock signals. Enrich shopping suggestions with usage-aware replenishment scoring so the frontend and LLM can prioritize real gaps and near-empty staples more reliably.
Keep /products/suggest lean by exposing product UUIDs and fetching INCI, safety rules, actives, and usage notes on demand through Gemini function tools. Add conservative fallback behavior for tool roundtrip limits and expand helper tests to cover tool wiring and payload handlers.
