-## Harness Notes
-- This batch is `standard` because REQ-020 changes persistence, interface surface, runtime flow, Streamlit UI, MCP tools, and baseline docs.
-- After this batch scaffold is committed, lead should issue a kanban-backed `lead -> delivery-runner` kickoff on the shared development execution board.
+## Delivery Notes
+- User explicitly prohibited Kanban for this recovery path; delivery was completed directly on feature branch `feat/bat-016-review-decision-workbench`.
+- Local verification evidence is recorded in `verification.md`; final merge remains subject to PR/CI review.
