Production

Goods Received, raw-material inventory (Inventory In/Out, FIFO consumption), the material price database, and batches. Schema in src/db/schema/raw-materials.ts, FIFO logic in src/lib/fifo.ts, batch lifecycle logic in src/lib/production.ts. UI reference: reference/SummitOS Production.dc.html.

• Materials Catalogue
  Master list of raw materials — identity, category/type/size/color, and current price with its source.
• Inventory In
  Receive a catalogue material against a Goods Received record — GR-balance enforced server-side.
• Inventory Out
  Draw stock for a Batch, a Project, or Indirect Material / Overhead — cost priced by FIFO automatically.
• Batches (Cost Tracker)
  Start a batch against a Designs requisition — Planning → In Progress → Completed.
