The file carried an identifier minted by the retired local hub while central
held a different record for the same file — ADR-010's same-filename,
different-UUID duplicate-registration class.
Central is authoritative (ADR-010 decision 1) and decision 6 says to mitigate
by changing the repository file rather than editing central, so the file adopts
central's id. The cache-side id dies with the cache.
