"""Condition B (English edition): the workspace agent (Antigravity CLI).

One trial = a fresh scratch folder (outside the repo, so the agent cannot read common.py or other trials) with
memos/ and API.md, then one headless `agy --print` turn. Afterwards the folder is copied back to trials/B<n>/ws,
checked with check.py, and scanned for the key.

Usage (from the textbook repo root):
  op run --env-file experiments/aib.env -- experiments/2_1_workspace/.venv/bin/python experiments_en/2_1_workspace/run_agent.py <trial_no>
op run puts AI_BUILDER_TOKEN only into this process and the agy process it starts; nothing is written to disk.
