+**Mixed-convergence pilot completed (2026-08-31).** The fresh State Hub plan
+contained nine replacements and 21 unchanged records. Projection preflight
+classified all nine as `legacy_source`, with zero already-derived or ambiguous
+units. The primary transaction migrated all nine rows, the atomic file phase
+rewrote the nine authoritative UUID fields in
+`CUST-WP-0038-state-hub-threephoenix-ha.md`, and verification returned old/new
+lookups 404/200 for every mapping. The repository was pushed in commit
+`14e865a` and exact-synced to the central projection. Approval evidence and the
+sealed plan/batch are in
+`docs/evidence/RMGR-WP-0005-state-hub-pilot-{plan,batch}-2026-08-31.json` and
+`RMGR-DEC-2026-004`. This closes the operational gate for the mixed-state path;
+T04 remains open only for the remaining fleet batches.

+**Adaptive-pricing rechecked (2026-08-31).** A fresh plan at synchronized commit
+`5ff416f` contains five unchanged records and no migration action: its
+authoritative files already carry the derived UUIDs. Batch planning therefore
+refuses with “repository has no migration action,” which is the correct no-op
+classification. No repair or mutation is warranted. The next batch must come
+from a regenerated fleet plan and select the smallest clean repository that
+still has at least one `replace` action; stale 2026-08-22 batch evidence must not
