Idempotent — running it twice on the same order is a no-op for items already in production. Composite SKUs get one assembly task plus one print job per kit part. Per-item failures (BOM shortages, missing print files) are returned in `shortages` / `unmatched_items` and never abort the rest of the order. ## OpenAPI ````yaml /api-reference/openapi.json post /orders/{id}/produce openapi: 3.1.0 info: title: AutoPrintFarm Public API version: 1.0.0 description: >- Public API for AutoPrintFarm — read + write surface for printers, jobs, inventory, orders, SKUs, files, worklist, and assembly. Authorization uses three scopes: `read` (any list/get), `write` (data mutations — create, update, delete, uploads, fulfillment), and `control` (physical printer actions: start, pause, resume, stop, heaters, light, filament).
