+## MASON-IN-0001 — Grandfather the legacy MASON-0001 identifier scheme

+title: Grandfather the legacy MASON-0001 identifier scheme
+status: open
+origin: residual
+origin_ref: MASON-WP-0002
+priority: low
+owner: ops-mason
+description: The finished bootstrap workplan uses legacy MASON-0001 and noncanonical
+  MASON-0001-Txx identifiers, including a duplicate T01. Fleet canon says existing
+  identifiers are never renamed and legacy schemes must be grandfathered. Coordinate
+  with the Custodian canon steward and Repo Manager to add the exact legacy scheme
+  mapping, then verify statehub consistency without rewriting registered UUIDs or
+  historical source identity.
