…and normalize after CTE inline Two fixes for LogicalOlapTableStreamScan handling in Nereids planner: 1. Override withVirtualColumns to return LogicalOlapTableStreamScan instead of LogicalOlapScan, preventing type downgrade during LogicalPlanDeepCopier.deepCopy used by CTEInline. 2. Move NormalizeOlapTableStreamScan execution to after CTE inline so StreamScans exposed by CTE expansion get normalized. Previously it ran inside notTraverseChildrenOf(CTEAnchor) which blocked traversal into CTE producers. This fixes CTE+stream hidden column queries and IVM incremental refresh failures caused by un-normalized stream scans.
Issue Number: close apache#65339 Related PR: Problem Summary: Normalize stream scan rules were executed in a late CTE-related rewrite topic, which could be skipped in trees with CTE-related traversal constraints, causing delta/rewrite paths to miss synthetic change_type/version project aliases and fail when buildDmlFactorExpr accessed hidden stream columns. This moves into the early table/physical optimization topic after partition pruning and removes the separate late topic from , and updates regression baseline for to the fixed incremental result behavior. None - Test: Regression test / Unit Test / Manual test / No need to test (with reason) - test_ivm_basic_mtmv (baseline .out updated) - Behavior changed: Yes (CTE stream-scan normalization now runs in the proper rewrite phase) - Does this need documentation: No

### What problem does this PR solve? Issue Number: close apache#65469 Related PR: apache#65468 Problem Summary: Several IVM aggregate regression cases used `REFRESH ... COMPLETE` before validating later incremental behavior. COMPLETE refresh does not advance the stream consumption offset, so the following `REFRESH ... INCREMENTAL` could re-consume historical changes and produce results that no longer matched the intended test point. This change updates the affected aggregate suites to establish the baseline with an initial incremental refresh, keeps the later COMPLETE refreshes that compare against snapshot ground truth, and regenerates the `.out` files so the expected results match the corrected stream-offset behavior. ### Release note None ### Check List (For Author) - Test: Regression test - `./run-regression-test.sh --run -d mtmv_p0 -s test_ivm_agg_2,test_ivm_agg_3,test_ivm_agg_4,test_ivm_agg_6 -forceGenOut --no-parallel` - Behavior changed: Yes (the affected regression cases now validate incremental results after establishing stream offsets with incremental refresh) - Does this need documentation: No

Problem Summary: Add a regression case for min_delta stream queries that project the stream change type column through a CTE and reuse that CTE twice in a self-join. The case verifies the output through an auto-generated .out file and keeps the existing stream regression coverage intact.

Issue Number: None
Related PR: None
Problem Summary: Stream scan planning had split state for snapshot and reset, while partition pruning still depended on table-specific non-empty checks that did not receive stream read semantics. This made the stream planning path harder to reason about and caused snapshot/reset handling to diverge from incremental reads. This change replaces the dual boolean state on logical stream scan with a single StreamReadMode enum, threads the optional read mode through LogicalCatalogRelation into selectNonEmptyPartitionIds, and lets the stream wrapper choose incremental pruning from stream.hasData while delegating snapshot/reset pruning to the base table path. The result keeps the read-mode semantics continuous from binding through rewrite and pruning, while preserving the convenience isSnapshot/isReset/isIncremental helpers on the scan node.
### Release note
None

- Test: Unit Test

- Does this need documentation: No

Problem Summary: This PR fixes two FE issues in the stream scan path.
First, when a stream scan appears inside a CTE,
NormalizeOlapTableStreamScanmay not be applied on the reused CTE branch, so the stream virtual columns are not lowered consistently and later rewrite steps see the wrong scan shape.Second,
PruneEmptyPartitionusesselectNonEmptyPartitionIdsbefore stream scan normalization. Forstream@snapshotandstream@reset, the old stream-wrapper pruning logic still used incremental stream visibility semantics, so a stream with no new delta could be pruned as empty even though snapshot/reset should still read snapshot data.This change keeps stream read mode as explicit logical scan state, threads that mode through
LogicalCatalogRelationinto partition pruning, preserves stream scan helper predicates on the logical node, and lets snapshot/reset pruning follow the base table path while incremental reads still use stream delta visibility. It also keeps stream scan normalization behavior consistent when the scan is referenced through a CTE.Release note
