serendepify-gsl-asr-ak-waxal-gnlp-whisper-small-balanced-fullft-v0.2

This is the second Ghanaian Speech Lab ASR artifact: a balanced Waxal+GhanaNLP full fine-tuning pass intended to improve WER beyond the Round 2 checkpoint.

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: 4000
• —Dev rows: 256
• —Max steps: 1200
• —Method: full fine-tuning from teckedd/whisper-small-waxal-round2-specaug-v1
• —Dataset mix: balanced Waxal + GhanaNLP from the v0.1 sanitized manifest
