"""ORCH-066: the meaningful Plane status model (layer B) — unit coverage.

These tests pin the layer-B behaviour WITHOUT touching layer A (the stage
machine). httpx is mocked; no network.

  * TC-03 (AC-3)  — the analyst start/resume indicates `Analysis`, not In Progress.
  * TC-05 (AC-5)  — entering the `review` stage indicates `Code-Review`.
  * TC-14 (AC-14) — set_issue_needs_input is unchanged (still PATCHes Needs Input).
  * TC-22 (AC-21) — STAGE_TRANSITIONS (layer A) is byte-identical (explicit pin).
  * TC-23 (AC-22) — QG_CHECKS registry + check_deploy_status contract unchanged.
