When an agent's output changes a schedule, a specification, or a supplier commitment, the consequence is material and frequently irreversible. Steel gets cut. A line gets sequenced. A tolerance gets released to a supplier in another hemisphere. Verification before commit is the only control that survives contact with the plant floor, because after commit there is nothing to roll back to.
Manufacturers also operate the most fragmented systems landscape of any industry: ERP, MES, PLM, QMS, WMS, and a supervisory layer that predates all of them. Agents are attractive precisely because they can reason across that fragmentation. They are dangerous for the same reason — a system that can read everything can write into the one place where a wrong value becomes a recall.
Orcher makes the boundary explicit. Engineering, quality, planning, and procurement authority are issued as distinct scopes derived from real organizational roles. Every write is reconciled against the governing system of record before it lands, and every commit is hashed with the approving human attached, which is exactly the traceability that product-safety regimes already demand.
