Why: Compiled workflow critics could resend a prior prompt output after document duty or publication changed across separate model guards.
Evidence: RED cross-guard revocation and retry tests; go test ./... -count=1 and targeted go test -race passed locally before commit.
Impact: Bind materialized prompt bytes to the engine step attempt and responded model receipt; recheck current project sources and epochs before judging, failing closed for unproven or ambiguous output.
