+description: PRD for supervisor/deploy_stage.py ConcurrentDeploymentError (G1/G2) reviewed 2026-08-07 -- consistent, no contradictions found
+metadata:
+  type: project
+---
+
+Reviewed the PRD "supervisor/deploy_stage.py 并发部署冲突的诊断化处理" (adds a named
+`ConcurrentDeploymentError` with `git_commit_hash`/`blocking_deployment_id`/`blocking_status`
+attributes, replacing the raw `sqlite3.IntegrityError` that currently escapes when
+`ux_deployment_active` rejects a concurrent `INSERT`; also backfills regression tests for the
+`rolled_back`/`blocked_pending_human` terminal-state release paths that
+`test_only_one_non_terminal_deployment_allowed` doesn't cover).
+
+**Why:** verified against the real code (`supervisor/deploy_stage.py:143-201`,
+`src/schema.py:305-306,332-333`, `supervisor/test_deploy_stage.py:171-180`) -- every factual claim
+in the PRD's background/已知事实 section matches current code exactly, including the
+staged→candidate_starting status transition sequencing and the exact set of terminal states
+excluded by `ux_deployment_active` (`finalized`/`rolled_back`/`blocked_pending_human`, with
+`health_check_failed`/`rollback_failed` explicitly and correctly called out as still non-terminal).
+No self-contradiction found between Non-Goals (no return-value/CheckoutFailedError changes, no
+app-level locking) and the FRs/ACs.
+
+**How to apply:** if this PRD or a follow-up SDD/task references G1/G2/G3 again, treat the facts as
+re-verified as of 2026-08-07; re-check `stage_deployment()`'s try/except structure before trusting
+this if it has been edited since. See also [[project_deploy_health_check_startup_timeout_comment_missing]]
+and [[project_deploy_health_check_http_timeout_comment_missing]] for other Deploy Supervisor PRD
+review history in this same area of the codebase.
