⚠️ CRITICAL: Anti-Hallucination Rules

1. Verify every claim with runtime evidence — run tests, read files, check actual output
2. Never fabricate bugs, imports, or file contents
3. If you cannot confirm something, say "I cannot verify this" instead of guessing
4. Before reporting a bug: read the full file, confirm it actually exists
5. Build succeeds = code is valid — do not claim broken imports when build passes
