Export SFT

Turn verified text attempts into conversational SFT JSONL. The environment runs each task repeatedly, the scorer marks correct attempts, and the exporter writes the passing conversations from the learning zone.

Files

• basic.py — run, select the learning zone, and export passing text attempts.
• passed_only.py — verify that failed attempts inside a learning-zone task are excluded from the training file.
• empty_zone_guard.py — remove stale output and guard the export when a selection has no useful rows.

When to use

Use this after _06_learning_zone/ has shown which tasks have a true middle-band pass rate. Exporting writes a dataset; it does not train a model. The next folder, _11_export_provenance/, inspects the sidecar that keeps scores and fingerprints beside the portable JSONL.

Tool-bearing runs are not representable in this text-only format and are skipped. See _17_tool_reliability/ for tool verification.

Run

python cookbook/environments/_10_export_sft/basic.py
python cookbook/environments/_10_export_sft/passed_only.py
