+Origin: RMGR-IN-0003. Net Kingdom has already repaired the original T08a
+source label, but the general ordinary-registration refusal remains.

+Preserve existing UUIDs on parent-qualified TNN suffix tasks marked done/cancel
+in finished, archived, or legacy completed workplans. Report their invalid
+labels in the assignment receipt and retain strict conformance diagnostics.
+Do not allocate historical UUIDs, accept unknown local aliases, or bypass any
+identity collision. Active or unbound invalid records still fail before writes.
+
+## Prove preservation and rejection boundaries

+
+Cover unrelated canonical allocation, unchanged historical source bytes,
+idempotency, dry run, invalid/missing UUIDs, active records, local aliases,
+and collisions. Run the complete suite and a read-only Net Kingdom preflight.
+
+Validation: 181 tests passed; targeted Ruff checks passed. Net Kingdom
+read-only identifier preflight passed with no assignments or file changes.
+RMGR-IN-0003 resolved; no implementation residuals.
