**Notes for maintainers**
-
`fe/fe-core/src/main/java/org/apache/doris/mtmv/ivm/IvmJoinDeltaHandler.java:557`
— Specialization uses original-relation uniqueness over direct equality slots;
nonunique, expression, residual and FULL OUTER paths retain their existing
repair logic.
-
`fe/fe-core/src/main/java/org/apache/doris/mtmv/ivm/IvmJoinDeltaHandler.java:590`
— Internal SUM is created after MV normalization; business aggregate
classification, normalized signature, original detail events and repair
sequence contracts remain unchanged.
- Existing validation logs inspected: FE/ASAN BE builds, Checkstyle, 194
focused FE tests and 7 regression suites passed; real chained LEFT/RIGHT plans
use SUM without repair ANTI joins. Formal review itself was read-only.
