+# Repository-qualified ad-hoc work-record identifiers
+
+Two repositories created the canon-prescribed `ADHOC-2026-08-23` workplan and
+task identifiers on the same day. Deterministic UUID derivation correctly
+refused the second registration because ADR-007 requires identifiers to be
+unique within the fleet namespace. Repair the naming convention rather than
+weakening collision protection or treating repositories as namespaces.
+
+## Correct the canonical identifier scheme
+
+```task
+id: CUST-WP-0066-T01
+status: done
+priority: high
+```
+
+Make `{PREFIX}-WP-ADHOC-YYYY-MM-DD` and its task suffixes canonical. Retain the
+unqualified historic form as grandfathered compatibility only.
+
+Completed in the machine-readable registry, prose standard, project-repository
+standard, repository instructions, and regression tests. This preserves
+ADR-007/ADR-011 namespace semantics and does not reinterpret repositories as
+namespaces.
+
+## Synchronize enforcement and authoring guidance
+
+```task
+id: CUST-WP-0066-T02
+status: done
+priority: high
+```
+
+Update Repo Manager's canon copy and State Hub's repository instruction
+templates and validators so newly authored records use the collision-free form.
+
+Repo Manager now classifies qualified daily ids as canonical and unqualified
+ones as grandfathered. State Hub's two instruction templates and legacy ADR
+validator use the same scheme; the validator explicitly permits the unchanged
+`ADHOC-YYYY-MM-DD.md` filename.
+
+## Repair and register the colliding Activity Core record
+
+```task
+id: CUST-WP-0066-T03
+status: done
+priority: high
+```
+
+Rename the not-yet-registered Activity Core record, reconcile it through the
+governed registrar, and preserve the successful ACTIVITY-WP-0035 and
+ACTIVITY-WP-0036 identifier writebacks from the partial attempt.
+
+The partial writeback was verified against the central projection and pushed as
+Activity Core revision `4d7623a`. The renamed daily record then registered as
+workplan `32d157b1-94b2-5d29-9b41-d3d9130cbb32` and task
+`330907a0-2899-5cbf-a056-4835c2f6faf8`; the registrar returned `applied` with
+correlation `f272ab73-35fb-44e7-aabd-23b124e3c135` and pushed revision
+`13aea81`. No actionable residual remains.
