   Returns `{ data: [...] }` or `{ kitchens: [...] }`.
 - `GET /{database}/kitchen/items?search_name=...`
   Returns item definitions for autocomplete.
+  Item payloads now expose category links via `categories` (array of IDs).
 - `GET /{database}/kitchen/items`
   Returns the current stock review list. Endpoint is paginated (`limit`/`offset`, backend default `limit=100`); frontend helpers aggregate pages by default unless explicit pagination is passed.
-- `GET /{database}/kitchen/items/grouped?expanded=0|1`
-  Returns grouped stock data; grouped review uses summary-first loading (`expanded=0`) and hydrates item children in background (`expanded=1`).
-  With `expanded=0`, child `items` can be ID-only stubs (`{ id }`) instead of full item payloads.
+- `GET /{database}/kitchen/items/grouped?expanded=true|false`
+  Returns grouped stock data; grouped review uses summary-first loading (`expanded=false`) and hydrates item children in background (`expanded=true`).
+  With `expanded=false`, child `items` can be ID-only stubs (`{ id }`) instead of full item payloads.
 - `GET /{database}/kitchen/items/{uuid_b64}`
   Returns one item detail payload.
+  Supports `allow_inactive=true|false` query filtering when needed.
 - `GET /{database}/kitchen/changes`
   Returns `{ since, next_cursor, changes }` feed payload for item/stock updates.
 - `POST /{database}/kitchen/items/upsert?mode=preview|apply`
   Used by label submit flow for create-or-update behavior and conflict-safe matching.
 - `POST /{database}/kitchen/items/lookup`
   Identifier lookup response includes source/freshness metadata (`source`, `cache_hit`, `stale_cache`, `payload_fetched_at`, `retry_after_seconds`) used for richer user feedback.
-- `POST /{database}/kitchen/items/{uuid_b64}/lookup?update=0|1`
-  Item-scoped OpenFoodFacts lookup used by stock detail to preview (`update=0`) or apply missing fields (`update=1`).
-- `POST /{database}/kitchen/items?label=1`
-  Used for label image preview rendering.
-- `POST /{database}/kitchen/items?label=1&preview=1`
+- `POST /{database}/kitchen/items/{uuid_b64}/lookup?update=true|false`
+  Item-scoped OpenFoodFacts lookup used by stock detail to preview (`update=false`) or apply missing fields (`update=true`).
+- `POST /{database}/kitchen/items?label=true&preview=true`
   Returns an image blob, `{ imageUrl }`, or `{ imageSvg }` for in-browser preview.
+- `GET /{database}/kitchen/items/{uuid_b64}/label`
+  Returns rendered label PNG for an existing item.
 - `POST /{database}/kitchen/items/{uuid_b64}/stock`
-  Creates a stock event for measured or descriptive updates using `{ quantity }` or `{ level }`.
+  Creates a stock event for measured or descriptive updates using `{ quantity }` or `{ level }`,
+  and for non-consumed gone transitions (for example `{ level: "gone", gone_reason: "spoiled" }`).
   Response shape is `{ status, stock }`; frontend re-fetches the item detail after successful update.
 - `POST /{database}/kitchen/items/{uuid_b64}/use`
-  Marks an item used up (`gone`) via stock-event semantics.
+  Marks an item consumed/used up (`gone`) via stock-event semantics.
 - `POST /{database}/kitchen/items/{uuid_b64}/print-label`
   Prints label for an existing item; called from the save flow when `Print` is enabled.
 - `PATCH /{database}/kitchen/items/{uuid_b64}`
   Used for item-level edits from stock detail (for example identifier code updates).
 - `GET /{database}/kitchen/locations`
   Returns a nested location tree.
+- `GET /{database}/kitchen/categories`
+  Returns categories (paged). Frontend now resolves category labels from
+  `categories_detail` when present, and falls back to this endpoint by ID.
