Scope

Fixes the MLWM alpha1 desktop/runtime neural path.

Root Cause

The alpha1 model was trained and promoted without a classical frequency-domain sync template, but the runtime embed path still injected that template before decode. That changed the image distribution enough for forced neural extraction to fail on a clean self-check.

Changes

  • Disable untrained sync-template injection for alpha1 neural profiles.
  • Skip geometric template rectification when sync is disabled.
  • Add a runtime unit test that locks alpha1 neural profiles to no sync template.

Validation

  • python -m unittest discover -s blind_watermark\\tests
  • npm run typecheck
  • .venv-ml neural ONNX smoke test: embed/extract ALPHA1-42, confidence ~0.998, engineUsed=neural

Rollback

Revert this commit to restore the previous sync-template runtime behavior, though that is expected to break alpha1 forced-neural extraction until a future model is trained with sync augmentation.
