 - Root `main` was clean at `0a86ec825a5803bf7e037d3b23c39be23238c43d`;
   that commit is an ancestor of coordinator closure `ae81949a49d7df3be4859e6c111235a991a504e4`.
 - The merge branch reached the exact coordinator closure by `git merge --ff-only`.
+- All non-`.project-docs` paths are exact-equal to released coordinator closure
+  `ae81949a49d7df3be4859e6c111235a991a504e4`; only canonical/task ledger paths differ.
+- `check_project_docs`, task-aware `check_doc_drift`, fixed-range `git diff --check`,
+  and clean worktree checks passed. Exact product-tree equality adopts the reviewed
+  `1,759 passed / 2 skipped`, pressure `1/1`, typecheck, lint, Windows package and
+  artifact verification evidence without rebuilding an unchanged product tree.
+- No live PostgreSQL or OpenAI command was run.
 
 ## Follow-ups
 
-- None recorded.
+- Complete the final root `main` fast-forward only if it is still clean at the exact
+  recorded base, then complete and release this main-merge task. Keep XWS/PostgreSQL,
+  paid OpenAI and production activation on HOLD.
