# GPU Batch01 Independent Review V1.2

Decision: `REJECT`

## Exact Blockers

1. All 97 features do not pass validation: calibration 94/97, holdout 46/97, and adversarial 67/97.
2. Supertrend ATR limits were frozen as zero by the runner, not at the approved bounded values. The period-10 ATR calibration drift is `7.105427357601002e-15`; the holdout drift is `1.4210854715202004e-14`.
3. Calibration-derived continuous limits do not generalize: holdout fails 48 Bollinger/Keltner requests plus three Supertrend ATR requests; adversarial fails all 30 Keltner requests.
4. V1.2 contains no performance artifact or complete runtime provenance.
5. ATR validation does not require ATR shape and NaN-mask equality before measuring finite errors.

## Satisfied Checks

- The contract contains 97 unique requests and was frozen before holdout/adversarial validation.
- Reported finite numeric limits are mechanically enforced.
- Donchian and PSAR outputs pass exact checks on supplied evidence.
- Supertrend bands, predicates, direction, transitions, and final outputs pass exact checks.
- Historical role semantics are honestly marked `UNVERIFIABLE_FROM_RECOVERED_SOURCE` and non-blocking.

`GPU_FEATURE_PARITY_CONTRACT_V1_2_VALIDATED` must not be issued.
