"""ORCH-059 TC-01/02/03: resolver registration of the dedicated "Confirm Deploy"
status and its fail-closed absence in fallback environments.

Contract (AC-1, AC-7):
  * TC-01 — _PLANE_NAME_TO_KEY maps the board name "Confirm Deploy" to the logical
    key "confirm_deploy".
  * TC-02 — get_project_states for an ORCH-like project (Plane API mocked to
    include a "Confirm Deploy" state) returns a NON-empty uuid under
    "confirm_deploy", distinct from "approved".
  * TC-03 — fail-closed: when the status is absent (API fallback to
    _DEFAULT_STATES / unreachable Plane), the key is simply missing and a .get
    access yields None WITHOUT raising — the confirm-deploy branch never activates.
