- A:
- L03 (changelog): hits=[] need>=2
- Q: Is 'last night backup OK' a good thing to bake into LoRA weights?
- A: No. LoRA weights should encode stable procedures, not transient state. Backup success/failure changes daily; baking it in immediately ages the model, wastes VRAM/disk, and creates false confidence if the next run fails.
## Recommendation
SOP injection improves scores. Use distilled SOP at cold start. Fine-tune only if mid-session drift remains a problem. Refusals not 100% (9/10) — do not promote any LoRA until refusals are perfect.
