### Search before asking - [x] I searched in the issues and found nothing similar. ### Paimon-cpp version Apache Paimon C++ `main` at `4027601`. ### Minimal reproduce step 1. Create a primary-key table and compact data files `A` and `B` into a positive level. 2. Build a source-backed scalar index payload whose immutable source metadata is `[A, B]`. 3. Commit an update which retires `A`, keeps `B` active with a deletion vector, and adds an uncovered replacement file `C`. The original payload remains active. 4. Scan an indexed predicate. ### What does not meet expectations? The reader currently validates a payload only when its complete source list equals the current active source set of the whole level. It therefore rejects `[A, B]` against active `[B, C]` and turns both surviving indexed data and the new file into ordinary scans. The payload still has a valid immutable ordinal namespace for `B`. The reader should reuse it for the active intersection, preserve the deletion vector on `B`, and leave only uncovered `C` on the ordinary scan path. Multiple retained payload groups should be accepted only when their active source intersections are disjoint; ambiguous overlap must continue to fall back. ### Anything else? The fix can remain read-side only: no public API, storage format, or index protocol change is required. ### Are you willing to submit a PR? - [x] I am willing to submit a PR. -- This is an automated message from the Apache Git Service.
