ci / image (pull_request) Has been skipped
Give experiments IDs (P0, E0-E11): registry, per-experiment layout, spec moved to docs/experiments/P0-pilot.md
Raw pilot data stays ignored (copyrighted text); blind key and numeric results are tracked.
Runner notes move into docs/infrastructure.

"""Run the pilot detectors over the pilot items. Resumable; one JSON line per item.
python experiments/P0-pilot/run_pilot.py --items experiments/P0-pilot/data/items.jsonl \
--out experiments/P0-pilot/data/results.jsonl --dry-run # no API calls: shows the plan
python experiments/P0-pilot/run_pilot.py --items ... --out ... --max-calls 400
Detectors (all see the passage and/or the Lean code, never the human labels):
lint static patterns on the projected simplex (no LLM)
role source-side simplex (LLM sees only the passage) aligned to the Lean simplex
judge one LLM call that sees passage + Lean and says faithful / not
compile the stored Lean verdict (``verified``), read from the items file
Hard stops: --max-calls bounds API calls; a rerun skips items already in --out.
