Layout

• checkpoints/checkpoint-*: PEFT/LoRA adapter checkpoint directories.
• manifest.json: sync metadata.
• run.env.redacted: training configuration with secret-like values redacted.

The paired rollout dataset is:

LLM-OS-Models/LFM2.5-8B-A1B-Terminal-ECHO-RLVR-Rollouts

That dataset stores the terminal actions, observations, verifier outcomes, and train-step metrics that produced these adapter checkpoints.
