- Sorted Gather does not track sort keys through aliases, retaining redundant exchanges and delaying filters
- `KeyCondition` ignores `cast_string_to_date_time_mode`: ISO `Z` literal rejected
- CBO underestimates join and partial aggregation costs when runtime filtering skews reader output
- Match `modulo` predicates against `moduloLegacy` keys only where the two agree
- trino dialect: fix array_except, flatten and reverse to match Trino semantics
- changes() predicate is bit identity, not IEEE equality plus a NaN guard
- mapAdd/mapSubtract throw BAD_GET on Decimal32/Decimal64 values
- Backward code-point count budgets a forward walk: rightUTF8 drops trailing bytes
