 ## Confirmation and Next Gate
 
 - Independent QC reran the exact PR #42 head and returned **PASS-WITH-NOTES** (acceptance blockers: 0). The note records that the fake-driver repository parity test is accepted AC evidence, while real PostgreSQL engine integration remains an explicitly documented environmental coverage gap.
-- `confirm-batch-verification` is complete: the batch is verification-confirmed, but **REQ-119~122 remain not Implemented** until the approved PR is merged to `main` and that post-merge gate is recorded.
-- The next action is PR approval and merge decision. `sync --live`, live broker/database access, deployment, and production remediation remain outside this batch verification and require their separate release approval gate.

 ## Recent Change Log Summary
 
+- 2026-07-15 :: REQ-119~122 **`Approved` → `Implemented`** (`confirm-req-implemented`, dcy-037/BAT-057): PR #42 merged to `main` (94e1489). Independent QC PASS-WITH-NOTES (acceptance blocker 0); 806 passed/47 skipped/1 deselected. `sync --live`, deployment, and production remediation remain separate release-approval work.
 - 2026-07-14 :: REQ-119~122 **승인(Approved, confirm-req, dcy-037)**: lead 검토로 각 REQ의 owner·priority·scope·검증 가능 AC와 Notes의 non-blocking 설계 제약을 확인했다. #39/#40/#41은 다음 `suggest-batch-reqs`에서 단일 emergency batch 후보이며, `sync --live`는 여전히 별도 release approval gate다.
 - 2026-07-14 :: REQ-119~122 **신규 생성(Proposed, draft-req, dcy-037)**: #39 fetched credential daemon/operator broker truth parity, #40 token/auth fail-loud empty-balance 분리, #41 managed non-holding divergence classification, runtime/interface/operations baseline 정합. #39/#40/#41 단일 emergency batch 및 `sync --live` 별도 release approval gate를 유지한다.
