> 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.
