"""ORCH-089 — integration: end-to-end auto-pass across pipeline edges.

Covers (04-test-plan.yaml):
  TC-23  both labels + all tech-gates green -> analysis -> deploy with no manual
         clicks (AC-3).
  TC-24  autoDeploy + a RED edge sub-gate -> Phase A not reached, Phase B not
         initiated (AC-5).
  TC-25  regression: no labels -> both gates manual exactly as before ORCH-089
         (AC-4).
