run_conformance/assert_conformant verify declared profile == observed behaviour (profile validates, READ round-trips to the right shard, unclaimed verbs raise NotSupported); ConformanceReport gives a precise capability diff. FolderAdapter passes; lying-read and dishonest-write stubs fail. 3 tests green. (TSD §A.2) Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
