Summary

  • Pin SA3 to the current head of Stability-AI/stable-audio-3#90, commit 9d0f559a58815ce44aa4ae5a1047f79f41090257.
  • Keep the canonical Stability-AI repository URL.
  • Mark the pin as temporary until the upstream PR merges.

Why

The MLX export path currently hard-clips decoded audio. PR #90 replaces that with shared no-boost peak protection. This pin lets us manually test whether the change removes the clipping heard with LoRA generations.

Impact

The model manager will report an SA3 update and reinstall the immutable PR-head revision. The existing generation interface is unchanged.

Validation

  • Confirmed the canonical archive resolves at the pinned SHA.
  • cargo test -p lsdj-app models::tests::sa3_pin_parses
  • JSON and diff checks pass.
  • Audio behavior is intentionally left for manual listening before this draft is marked ready.
