# Engine Capability Graph Snapshot

This generated snapshot is the only place spec docs should cite volatile AI capability counts. `buildEngineCapabilityGraph` is the canonical source. `semanticContract.buildEngineCapabilitySnapshot` remains a derived view and should not be hand-maintained.

Graph version: `engine-capability-graph.91d7d5cfdd28c8e8`.
