mrr-data is the physical data plane for Meta Relational Reasoning. MRR owns semantic identities, generations, queries, and result admission; this repository owns Arrow interchange, bounded physical execution, snapshots, and optional storage providers. Arrow is the only default feature.
- Architecture and ownership: Data-plane RFC
- Implemented APIs, feature contract, and development commands: Current implementation
- Content identity, local cache, snapshot, and S3: Content cache protocol
- Snapshot transport acceptance: S3 and Kache transport audit
- Property snapshot and worker: Property snapshot and Healthcare query audit
- Existing POO Flow static-edge consumer: Integration guide
Run just test-property-query for the original Healthcare GQL worker path, and just clippy-property-query for its strict lint gate. The current implementation lists broader workspace and optional-provider checks. CI validates Ubuntu and macOS independently.
The Lambda/Marlin typed native handoff is a separate acceptance gate; the property-row producer and worker tests alone do not prove an application invocation.
