Fix Modal fine-tuning scripts for YOLO26n and MiniCPM-V before running
Takeaway: Next time I'd ask it to actually dry-run or at least trace the Modal image build and dataset serialization steps against Unsloth's current examples, not just review the code — the static review missed both the apt-get ordering bug and the PIL/Arrow serialization issue, which only showed up once I actually ran it on Modal.
Fix MiniCPM-V fine-tuning pipeline on Modal with Unsloth
Takeaway: Next time I'd tell the agent upfront to check the model card on Hugging Face for the exact transformers version needed, since half the debugging loop was chasing version mismatches (MiniCPM-V-4.6 model_type not registered, then peft/transformers pin conflicts) that a single doc check would have caught.
