Summary

• Resolve Snowflake WHERE references against input columns before SELECT aliases, including quoted names and correlated subqueries.
• Preserve lambda scoping with capture-avoiding parameter renaming and bound recursive alias expansion by reference and AST-node budgets.
• Keep the behavior gated to the Snowflake SQL dialect; other dialects retain their current planner path.

Validation

• Snowflake live probes confirmed input-column precedence, inner-alias precedence over outer columns, and lambda capture behavior.
• datafusion-sql integration: 655 passed.
• cargo fmt --all --check passed.
• cargo clippy -p datafusion-sql --tests passed with the pre-existing datafusion-expr nonminimal_bool lint allowed.
• Independent read-only review approved the final diff.

Rustice will remove its schema-blind WHERE AST rewrite and pin this revision.
