monitors-evaluation-awareness

"""Build the Hugging Face dataset Netzerep/monitors-evaluation-awareness: one table, one row per monitor review.
Run with:  uv run --with pyarrow python -I scripts/build_dataset.py
Writes data/reviews-*.parquet, docs/ and build_report.json next to this folder. Sources are read only.
A row holds the case (benchmark, task, labels, the agent transcript the monitor saw and, for SHADE, the full agent run),
the monitor's transcript and decision, the V-EvA judge's labels and any hand labels. Rows are natural reviews
(setting "standard") and continuations of prefilled monitor reasoning ("prefill"), by the readout's four monitors.
Monitors and prompt variants the analysis did not use (the Claude Opus 4.8 reference, Qwen3.5-27B and its live-traffic
prompt) are left out (lead, 2026-11-08).
Sources (as of 2026-11-04):
  REPO  the monitor-incrimination-research checkout (its experiment folders)
  SP    the V-EvA readout's working copy (a Claude session scratchpad). It is the newest copy of the readout's BashArena
        and SHADE monitor outputs and judge labels; the repo's readout/ copy predates the second extension, SHADE and K = 4.
The project's experiment numbers and batch names appear only in the source paths below, not in the dataset.
As of 2026-11-08 SP no longer holds its raw data, so this script cannot be rerun as is: later versions are made by
patching the published shards (scripts/patch_v1_*.py), and this file keeps the same rules for reference.
