Versioned additive-optional migration (L10 scoping step-2 ruling): a checkpoint schema bump is a recorded lineage transition, not death-and-rebirth. - engine_state.load_manifest() now REFUSES (IncompatibleEngineStateError) a checkpoint whose schema_version > this build's _SCHEMA_VERSION, and tolerates <= current (older/equal read any missing newer fields via additive-optional defaults). Never silently mis-loads newer state. - chat.runtime._load_engine_state() loads the manifest FIRST so the version refusal gates before any recognizers/candidates are read. - DerivedRecognizer.from_json documents the additive-optional convention (new fields .get-defaulted + omitted-when-default), mirroring DiscoveryCandidate. Tests (TDD): refuses newer schema_version; tolerates older. Prerequisite for the L10 continuity spike's P2 byte-identity gate (it may now assume a fixed schema within a run, with version bumps handled explicitly). |
