Manufacturing — production orders and station scans

A production order kicks off a build — pulls the bill of materials forward, reserves inventory, and tracks the build through every station to a finished good with a serial.

Creating a production order:
1. Manufacturing → Orders → New
2. Pick the product (the BOM auto-populates as a kit reservation)
3. Enter quantity to build
4. Pick due date and target line/cell
5. Optional: assign an operator or leave open for the line lead to claim

The kit reservation:
The moment you save the order, the BOM components are reserved against current inventory. If a part is short, you see it before the operator does. Available actions:
• Pull from another order (returns reserved inventory to free pool, then reclaims it)
• Substitute a compatible part (logged as a BOM deviation; requires sign-off in regulated mode)
• Wait for the next receiving (production order goes to "Awaiting parts" status)

Station scans:
At each station, the operator scans:
• Their badge (operator ID)
• The order tag (production order ID)
• Each component going into the unit (lot or serial)

Each scan adds a row to the genealogy ledger. In regulated mode, the row includes a digital signature and chains to the previous row's hash.

Hardware:
• Phone camera — works out of the box; uses the device's barcode scanner via the browser
• USB scanner — appears as a keyboard input; drop it into any scan field
• Bluetooth ring scanner — same as USB, just wireless

Finished goods:
When the last station scan completes, the order auto-finalizes:
• Each unit gets a serial number (or a lot ID for batch products)
• Inventory increments for finished goods
• Genealogy ledger snapshot is sealed
• If linked to a customer order, the units are auto-allocated to ship
