# Independent reproduction protocol

This protocol reproduces static fixture controls only. It is not an engine test or third-party audit.

1. Download all ten files into an isolated directory and record checksums.
2. Confirm `verify-200GB-20260831.py` imports only Python standard-library modules.
3. Read the assumption register and held-observation register before running anything.
4. Do not submit, execute, dry-run, explain, or profile `query-plan-fixture-200GB-20260831.sql`.
5. Run `python3 verify-200GB-20260831.py` from the download directory.
6. Independently recompute 400 × 4 × 125,000,000; the 30/400 window bound; column-allocation conservation; and top-five contribution values.
7. Inspect the SQL text for explicit columns, half-open date bounds, `is_internal = FALSE`, aggregation, deterministic rank, and top-five selection.
8. Report interpreter version, checksums, PASS/FAIL output, deviations, and organizational relationship.

Passing supports only deterministic consistency of the static package. Engine plans, pruning, runtime, processed/scanned/billed bytes, cost, output, capacity, and SLA remain unobserved. InfiniSynapse internal reviewers are not independent external validators.
