Frostyverse H-109 build validation
==================================

Validation profile completed successfully before packaging.

Key validation results:
- Reduced-domain wedge generation recheck: PASS
- Wedge-only vs full field relative difference: 1.233e-10
- Wedge-only validation photon miss: 2.665e-15 FrostCells
- Unbuffered exact direct-read provider field rel difference: 2.278e-16
- Direct-read validation photon position/vector miss: 0.000e+00 / 0.000e+00
- Route / wall hits identical: True / True
- Fixed exact field cache: 64.000 KiB
- Validation high lane: exact path miss 0.000e+00, route/hits True/True
- No memory-mapped wedge in compact photon lane
- No learned surrogate, GR scoring, gravity retuning, or node-law change

The full R80 holdout was NOT run during build validation.
