+Inventory rows store `(user_id, class_name, quantity, notes, visibility,
+quality)`. Adding an item that is already present increments its quantity;
+quantity, notes, visibility and quality can then be edited or the row removed.
+Every added item starts `private`; the Visibility toggle switches it to
+`available` and back. Responses are enriched live from the catalog.
+
+`quality` is an optional mining/refining value from **1 to 1000**. It is only
+accepted for commodities that are actually mineable — ores, minerals and gems
+(and their refined/raw/pure variants). Gases, organics, processed goods, crafted
+alloys and salvage are excluded. The catalog exposes this as
+`quality_applicable`; the UI shows a Quality input only for those commodities.
+`null` means the owner has not recorded a quality. On `PATCH`, sending
+`"quality": null` clears it, while omitting the field leaves it unchanged. Each
+inventory row holds one quality (the schema keeps one row per commodity, so
+different quality lots are not separated). If a catalog item disappears after a
+dataset refresh, the row is reported with `available: false` instead of being
+silently deleted (`available` is about the catalog, `visibility` is the owner's
+classification).
+
+The **Available** tab (backed by `GET /api/v1/available`) is public, like the
+catalog: it lists every row marked `available` across all accounts with the
+item's catalog details, quantity, quality (when applicable), owner username and
+last update. Private rows
+never appear there and inventory notes are never exposed.
+
+Clicking an item name in either **My Inventory** or **Available** opens the same
+catalog detail view used by the catalog grid.
