Task-attempt ledger, human gold labels, per-task action traces, token/cache
metrics, and the self-improvement loop's change+gate ledger from
PincerCraft, a Minecraft agent
(Mindcraft fork) whose design rule is "code owns the facts, the LLM owns
the plan." Every task attempt snapshots inventory before, re-measures

delta — the model's own "done!" counts for nothing.… See the full description on the dataset page:
