# Independent reproduction protocol — CHDB-20260831

Scope: local static file review. No network, database, SQL execution, subprocess, parser-conformance, performance, or deployment evidence.

1. Obtain the ten files from the canonical page and record version 2026-08-31.
2. Confirm all SQL files say DO NOT EXECUTE.
3. Compare accepted and rejected grants byte-for-byte with the rules.
4. Compare all seven matrix rows with expected-lint JSON.
5. Run `python3 verify-CHDB-20260831.py` using a trusted Python 3 interpreter.
6. Retain verifier output and file hashes.
7. Report only internal consistency. Do not describe the replay as a third-party audit or as effective-access proof.

Independence requires a reviewer who did not author the package. Internal reviewers do not qualify. Real access verification requires separately authorized target-system evidence.
