+# 🌾 Verdi AI OS: Whisper Small Shona ASR (Stage 1c Mastered Core)
+
+This repository hosts a completely standalone, fully compiled model optimized natively for the Shona language (`sn-ZW`).
+
+## 📊 Training Progression Metrics
+- **Stage 1a (FLEURS Baseline):** Baseline WER dropped to **37.15%**
+- **Stage 1b (Bible Chunk 1):** Dropped WER to **29.39%**
+- **Stage 1c (Bible Chunk 2 & 3 Increments):** Achieved new floor of **25.52%** WER.
