The products table conflated catalog ("kind of thing you scan") with
instance ("this jar I bought") — splitting it lets us record every
purchase as its own asset and autofill brand/shop/price/THC from the
last instance when scanning a known SKU.
- products: sku + strain + name + type + kind (catalog only)
- inventory_items: physical jars with short-UUID asset ids, per-batch
brand/shop/bin/price/cannabinoids/weight, audits, lifecycle
- audits now key on inventory_id; strains lose brand_id and type
- migration: rename existing products/audits/strains to *_legacy on
first boot so users keep historical reference, fresh start otherwise
- two-step add flow: scan SKU → select/create product → instance
details (autofilled from last instance) → generated asset id shown
- ScanField matches asset id first, falls back to SKU
- inventory list defaults flat, "By product" toggle groups instances
