# GPU Batch01 V1.2 Frozen Validation Contract

All 97 observed Batch01 outputs are evaluated against `historical_band_channel`.

## Evidence Classes

- Donchian and PSAR outputs: exact.
- Bollinger and Keltner outputs: bounded by calibration-only limits.
- Supertrend final output, bands, direction, transitions, and branch predicates: exact; ATR uses supplied fixed bounds.

## Frozen Coverage

- `bollinger`: 36
- `donchian`: 10
- `keltner`: 36
- `psar`: 3
- `supertrend`: 12

## Role Status

Unrecovered strategy roles are `UNVERIFIABLE_FROM_RECOVERED_SOURCE`; they are recorded but are not parity blockers.
