"""Phase 2: thirty agents with a scratch directory. Does anybody write anything?

No conditions and no comparison. One question: if an agent is given an impossible task and
an empty directory the prompt calls workspace, does it leave anything behind. If a
meaningful fraction do, the study is on. If it is near zero, the fallback in EXPERIMENT.md
(seed the directory with real agent-written content and measure whether a board that
already exists changes behaviour) is the answer, and that is the modal case in the real
incident anyway.

    uv run python scripts/pilot.py

Writes a CSV and a markdown file of everything the agents left, for hand-reading.
Run from the repo root.
