-Routine Railiance Apps sync stopped on seven completed, UUID-bound historical
-RAILIANCE-WP-0004-I01..I07 tasks while publishing the invited Vergabe pilot
-contract. Extend the existing historical-binding preservation path for exactly
-this closed parent and these labels. Conformance reporting remains strict;
-active/unfinished tasks, unbound or invalid UUIDs, other parents and I labels
-outside the observed set still refuse. Preserve existing source IDs, UUIDs,
-statuses and historical references. New records continue to require canonical
-IDs. No Hub identity mutation or sealed UUID migration is involved.
-
-The attempted label-only normalization was withdrawn before commit/projection:
-ordinary sync does not rename nonblank task record IDs, and changing the UUIDs
-would enlarge the task without improving the pilot. This explicit historical
-preservation resolves the routine sync blocker. Canonical migration remains the
-existing RMGR-WP-0005 programme, not a new pilot prerequisite.
-
-Validation: targeted historical/identity regression suite and Ruff, plus an
-actual Railiance Apps dry run preserving all seven bindings without assigning
-new UUIDs to them. Parent return is RAPPS-WP-0014 and HFACT-WP-0001.
