# [DEF:backend.tests.services.clean_release.test_publication_service:Module]
# @TIER: CRITICAL
# @SEMANTICS: tests, clean-release, publication, revoke, gate
# @PURPOSE: Define publication gate contracts over approved candidates and immutable publication records.
# @LAYER: Tests
# @RELATION: TESTS -> src.services.clean_release.publication_service
# @RELATION: TESTS -> src.services.clean_release.approval_service
# @RELATION: TESTS -> src.services.clean_release.repository
# @INVARIANT: Publish requires approval; revoke requires existing publication; republish after revoke is allowed as a new record.
