K6 — log a bake (Packaging)

Packers bake. The floor works early mornings on a standing plan, but the night team routinely puts things in the oven — a shortfall they can cover, a last-minute addition — and this records it instead of sending them to another department's app.

It is a packaging-owned log, not a production record: a production requires a recipe and the platform has none, so this works on day one and can be reconciled into production later (D-21).

Append-only. No edit and no delete in v1 — a bake log records something that physically happened, so a fat-fingered quantity is corrected with another entry, never a silent rewrite of history.

locationId is optional: shelves may not be labelled yet, and an inventory gap must degrade rather than block (PK-4). The response carries the item's refreshed inventory row, so the on-hand chip updates without a second call.

⚠️ Send bakedAt. The night shift crosses midnight, and the server clock cannot tell which night a packer thinks they are on — the screen can. Which day production belongs to at all is a still-open question; see §4.1 of the Phase 5 plan.
