Lock the spec. Then assign the crew.

Supervised work OS. Masters lock the WorkSpec on this clipboard. Qualifications hang on the rack. Workers seal WorkProof. Workers cannot lock a spec. Assign only after lock plus a verified qual. Not a job board. Not commerce.

Qualification rack

No verified qual, no assign.

Each tag is a trade stamp against the locked WorkSpec. A pending card, an expired ticket, or a missing trade refuses the crew. Masters lock. Workers execute. Supervisors review the seal.

Not a job board. Spec, qual, assignment, proof.

Assign only after lock.

Workers cannot lock specs. A draft WorkSpec shows no crew. A verified qual on an unlocked spec still refuses. Sealed WorkProof is the close — this engine has no money cents.

Proof / lock

Hash the spec. Seal the WorkProof.

The locked WorkSpec content hash rides on the assignment and on the sealed proof. There is no till and no typed amount. A draft spec cannot be assigned, and an unsealed run is not complete.
