- Submitted Model 1 checkpoint SHA-256:
  `1cfd6f501fffd0092635221444a104d181cd5117a0c67c8c1ac484701bb7669a`.
- V42 checkpoint SHA-256:
  `e3cca8d8499b9eeee29912fbf94af734a4e903bd3b49174babcdd095c829a021`.
- Parameters: 412,204.
- Tensor transfer: exact for reducer, MAC, subtraction, factor, cancellation
  judge/revisor, prime-two router, operation policy, and phase policy.
- Scalar clock training: 1,200 Adam steps on all 513 initial-clock and all 513
  decrement-clock labels; every distilled decision exactly matches Model 1.
- Fresh/reload raw Tier 1--10: 300/300.
- Sealed hard corpus SHA-256:
  `2f4453cdfe3bc1a96d811f8c1e17c1d58cac6a893d3a501d92cff5b6f4a30fbc`.
- Sealed hard corpus: 960/960, including 911/911 nonzero answers.
- Official CPU sandbox: 1,000/1,000 scored Tier 1--10 in 66.4 seconds.
- Same-seed Model 1 controls: 69.0 seconds before and 93.3 seconds after.
- Official result JSON SHA-256 for V42 and both controls:
  `a4f4e3de7e2d20d308b89d5c1e16b3304376d45f3b5227e3ccdb8f7a7773a10c`.
- Exact-package randomized weights: 0/73 correct nonzero answers.
- Official static checker, preprocessing isolation, determinism, and strict
  checkpoint loading: pass.

The public evaluator image used for the comparison was
