Custodian historical identity compatibility

Origin: the user's HFACT-WP-0001 critical-path continuation and delegated legacy ID side quest; historical reconciliation remains CUST-IN-0017 in the-custodian. Review found valid historical suffix IDs and parent-local TNN aliases rejected by the new global identity gate. Preserve the existing source labels and UUIDs.

Audit the exact source and Hub bindings

Read-only audit covers nine historical workplans and 54 existing task UUIDs. The 38 local aliases are qualified by their original parent in the projection. The actual State Hub derive/merge path retained all 54 task UUIDs, parents and statuses in memory against a current HTTP snapshot; no rows were created or cancelled. Three unrelated missing qualified ad-hoc source bindings already match the deterministic UUIDs held by the Hub and may be restored by the normal identifier tool. See docs/evidence/2026-09-09-custodian-legacy-identities.json.

Add bounded compatibility without weakening new identities

The kind registry enumerates the historical suffix IDs and each observed local alias range. Parent scoping applies only to those accepted local aliases with an existing managed UUID. Canonical qualified IDs remain globally checked. Unknown aliases, same-parent UUID collisions and missing local UUIDs refuse ordinary registration. The Custodian machine canon carries the same historical interpretation; no new identifier convention is introduced.

Verify safe registration and hand off broader reconciliation

Repo Manager suite: 169 passed. Portable tests cover global canonical collisions, parent-local collisions, unknown parent/alias, missing UUID, immutable source bindings and all 38 aliases. Full Custodian dry run now passes the identity gate. Ordinary sync must still prove its exact pushed commit and primary receipt. No retirement acknowledgement is granted by this compatibility change.

Residual handoff: CUST-IN-0017 remains open for historical duplicate projection rows (including CUST-WP-0010b source UUID def8455a-9de4-4891-a15a-5b09ca98ab1e versus stale duplicate 416ff571-18cf-5cb2-9c8b-836f68a301b3), retired/orphan history and the CUST/THE instruction-generation conflict. HFACT-WP-0001-T02 retains task-field projection completeness and semantic idempotency keys. This workplan closes only the bounded identifier-compatibility defect.
