- `metadata.json` - `{"skip": true}` or `{"skip": false}`
- `query.sql` - T-SQL to parse
- `ast.json` - Expected AST output

## Important: Never Modify ast.json

**NEVER regenerate or modify `ast.json` files.** These files contain the expected/correct AST output that the parser should produce.

If a test fails because the parser output doesn't match `ast.json`:
- Fix the **parser** to produce the correct output
- Do NOT update `ast.json` to match what the parser currently produces

The `ast.json` files are the source of truth for correct behavior.
