"""POST /prompt enforces canonical-UUID job ids at creation time.

Lives in assets_test because it uses this suite's booted-server fixture and
because the invariant exists for the assets pipeline: the GET /api/assets
``job_ids`` filter matches stored job ids exactly, so a job minted with a
non-canonical id would produce assets the filter can never find.

The prompt bodies here are intentionally invalid workflows — prompt_id
validation happens before workflow validation, so a rejected id returns
``invalid_prompt_id`` while an accepted id falls through to the ordinary
workflow-validation error (proving it cleared the id check).
