"""ORCH-036 TC-15: the deploy-verdict parse contract is unchanged (AC-10).

``_parse_deploy_status`` reads ONLY the machine-readable ``deploy_status:`` YAML
frontmatter (never prose). ORCH-036 produces the verdict differently (a
deterministic finalizer instead of an LLM), but the parse contract that the gate
relies on must remain bit-identical:
    SUCCESS -> (True, ...), FAILED -> (False, ...), no/!frontmatter -> (False, ...).
