serendepify-gsl-asr-ak-waxal-whisper-small-only-lowlr-freezeenc-fullft-v0.4

This is a Ghanaian Speech Lab ASR artifact: a Waxal-only low-learning-rate full fine-tuning pass from the Round 2 checkpoint with the Whisper encoder frozen.

It is a real training run, not a smoke-test checkpoint, but it is still a review candidate until the held-out evaluation and failure taxonomy are complete.

License is set conservatively because this pass includes Waxal-derived data.

—Training rows: 9138
—Dev rows: 1024
—Max steps: 600
—Method: full fine-tuning from teckedd/whisper-small-waxal-round2-specaug-v1
—Dataset mix: Waxal only from the v0.1 sanitized manifest
—Frozen encoder: True
—Stop on first regression: True
