+  - no dump is authorized.
+- The prompt's section 6C now requires all of the following:
+  - inspection responsiveness;
+  - a cancelled reclaim that leaves the fixture unchanged;
+  - reclaim of one landed row and one locked row (unlock-before-remove), with
+    exact `removed-branches.log` tip entries;
+  - dirty-row protection;
+  - branch recovery from the logged tip;
+  - byte-identical controls and sentinels.
+- #560 and the Worktrees parity rows stay `Partial` until that gate passes.
