Cancel Job

Stop a job that has not finished, and release its money hold.

A video can run for minutes against a reserved balance, and until now there was no stop button: a request sent by mistake had to be paid for and waited out (parity audit 2026-08-30).

Two guarantees:

• The transition is GUARDED on the row still being non-terminal, exactly like settlement's claim. Cancelling cannot resurrect or overwrite a job that already completed, so a clip that landed a moment earlier stays completed and stays billed for what was really delivered.
• The hold is released, never charged. Cancelling costs nothing.

Cancelling is best-effort against the SUPPLIER: the render may already be running on their side and we may still be invoiced for it. That is our cost to absorb, not the customer's, which is why this bills zero rather than pro-rating something unverifiable.
