### Describe the subtask Complete and document the five-family compatibility contract for Paimon 1.2. **Compatibility outcomes** - **Nanosecond timestamps:** Round-trip exactly through Paimon precision-9 timestamp types; reject precision 10 through 12. - **Variant:** Round-trip through Paimon's native Variant type. - **Unknown/Null:** Reject. - **Geometry:** Reject. - **Geography:** Reject. **Acceptance** - Reproduce all five families through the connector's public create/conversion path and its alter/load paths where supported. - A supported mapping must round-trip without losing type identity or parameters. - An unsupported mapping must return `IllegalArgumentException` before external metadata mutation; no fallback to a narrower or opaque type is allowed. - Cover nested types where the connector supports complex columns. - Add focused converter/operation tests and an integration or no-side-effect test appropriate to the connector. - Update the connector documentation with a five-family compatibility matrix and rejection rationale. - Keep implementation commits atomic by connector and type family. **Connector-specific verification** Reproduce supported cases with a real filesystem catalog create/load round trip. Verify rejected create and mixed alter operations leave columns and properties unchanged, then run the focused and full module suites. **Documentation** `docs/lakehouse-paimon-catalog.md` ### Parent issue #12056 -- This is an automated message from the Apache Git Service.
