Research direction
Start by locating FlinkSourceEnumerator and compare its source-split assignment with the referenced Paimon ContinuousFileSplitEnumerator implementation. Clarify how optional channel selection should work and which existing source-enumerator tests cover split assignment. Done means the enumerator supports the requested optional channel-selection behavior with matching test coverage.
