The dictionary release was republished as dict-v1.0.0 so that dictionary tags stop using calendar versions. The release was renamed rather than rebuilt, so the assets are byte-identical and every SHA256 in product-lock.json is unchanged; only the tag string moves. Downloads under the old tag now return 404, so this pin has to follow.
The runbook example and the fixture standing in for a current release move to the semver form too. LEGACY_DICTIONARY_TAG and the retired-repository fixture keep their calendar names because they identify historical releases that stay immutable.
