Why: Revoked project material could remain in later model turns, and plugin Audit could impersonate a model-input manifest.
Evidence: SELF red tests reproduced both paths; updated project revocation, trusted receipt, migration, and entrypoint tests pass locally with go test ./... -count=1 and targeted race checks.
Impact: Rebuild direct model requests after scope changes, sanitize or block unproven generic history, omit legacy project injections, and persist manifests in a dedicated state-checked table.
