> Calcite masks view validation errors with ClassCastException in ViewAliasCorrector. For t(b BOOLEAN, ts TIMESTAMP): CREATE VIEW v_sum AS SELECT q.n FROM (SELECT SUM(b) n FROM t) q; SELECT n FROM v_sum; Using TRUNC(ts, 'DD') instead of SUM(b) gives the same crash. Direct expressions produce normal AnalysisException. Alias correction assumes every SELECT item is a qualified column with AS. The fix checks this shape and preserves unaffected items during correction. Reproduced at 2f022a5ca0fc99670bcf197a1f89016cdf78d114 without planner fallback. Five baseline regressions fail with ClassCastException. With the fix, Java build and 18 related Maven tests pass. Full upstream precommit and E2E are pending.
