"""ORCH-016 / TC-16 + AC-6: analyst status-only regression.

Status-only verdict model (PR #12 / #13):
  - analyst finishes its run -> Plane state becomes In Review,
  - ONE status comment is posted asking the stakeholder to flip the status to
    Approved (or write a reason and switch to Rejected),
  - NO auto-advance happens — the next stage waits for human approval.

The ORCH-016 PR refactors the comment text into the unified status-comment
helper. This regression test guards against:
  (a) the analyst path silently auto-advancing,
  (b) the analyst comment losing the «Approved» / «Rejected» instruction text,
  (c) the comment switching authorship away from the analyst bot.

We exercise `_handle_analysis_approved_flow` directly (the launcher path).
