COMMENT-AWARE TRAINABILITY AUDIT
================================================================================================================
Raw regex matches, including comments: ['base_weight', 'x']
Executable ggml_set_param calls: ['x']
Expected executable calls: ['x']
[PASS] X is the only gradient probe.

Step 3 is complete.

The next stage is a native one-layer Q1 + LoRA optimizer-step test where only LoRA A/B receive gradients and AdamW state.
