Qwen3 Article-Usage Micro-Coach — v2

This is a dequantized MLX fusion of a QLoRA adapter trained from mlx-community/Qwen3-1.7B-4bit. It asks one conceptual coaching question about one English article error without revealing the correction. After the learner independently fixes the target, it responds exactly Target fixed.

Frozen 60-case adapter results

Model Spec adherence Robustness Mean usefulness
Untuned Qwen3 1/60 (1.7%) 1/30 (3.3%) 0.100
Dataset v2 adapter 43/60 (71.7%) 23/30 (76.7%) 1.433

Before upload, this dequantized fusion reproduced the adapter's pass pattern on a five-case semantic parity check: 4/5 passes and 1.600 usefulness. The remaining failure was the same known wrong-concept case as the adapter.

This model is not reliable enough for unsupervised teaching. Its largest remaining failure is asking a well-formed question about the wrong article rule.
