"""ORCH-036 TC-01/02/03: deterministic exit-code -> deploy_status mapping.

The finalizer (Phase C) maps the host-hook exit-code to the machine verdict via a
PURE function (no LLM, no I/O), so it is unit-testable in isolation. Contract
(hook exit-code 0/1/2, AC-1/AC-3): 0 -> SUCCESS; 1 (rolled back), 2 (rollback also
failed), and anything else -> FAILED (fail-closed).
