Each bundle is served from the attested copy of DB Migration Patterns, so the file you download is the one covered by the governance receipt on this page rather than whatever currently sits at the upstream source.

Provenance

  • Catalog identifier: ecc-db-migration-patterns
  • Harvested from the upstream repository.
  • The manifest hash below is what the signing key committed to. A bundle whose digest does not match it is not the attested DB Migration Patterns.
  • Anything published here has been through the same gate, so a missing receipt is itself a signal rather than an omission.
