> `CorrelateRestoreTest.testRestore[8]` (`CORRELATE_WITH_LITERAL_AGG`) is
> intermittently failing because the test asserts exact changelog record
> ordering, but the multi-source streaming plan produces non-deterministic
> record interleaving after restore.
> The plan has three independent sources feeding into two streaming joins
> (InnerJoin, LeftOuterJoin, SemiJoin). Post-restore, when `source_t2`'s record
> reaches the SemiJoin before the retract cascade from the
> GroupAggregate+InnerJoin pipeline completes, the `-D[3]` and `+I[3]`
> changelog records are never emitted in the expected window.
> The test was introduced in FLINK-37882.
> {code}
> Expecting actual:
> ["+I[2]", "-D[2]", "+I[2]", "+I[3]"]
> to contain exactly in any order:
> ["+I[2]", "+I[3]", "-D[2]", "-D[3]", "+I[2]", "+I[3]"]
> but could not find the following elements:
> ["-D[3]", "+I[3]"]
> {code}
> *Fix:* Switch from changelog assertion to materialized data assertion using
> the existing `testMaterializedData()` + `consumedValues()` pattern (already
> used by `MultiJoinTestPrograms` and `DeltaJoinTestPrograms` for the same
> class of non-determinism). The expected materialized state is `[+I[2],
> +I[3]]`.
