config/ci/ contains only overrides needed inside Docker test runs (fixture paths, fake database id, scratch tags_dir). It does not duplicate drives.yaml — load_config falls back to the parent file when config/ci/drives.yaml is absent.

CLI_CONFIG_DIR=config/ci is set automatically in Docker test scripts and in tests/conftest.py (autouse) so integration never writes to iCloud or home config paths.

• contest/templates/ — copy-paste scaffolds for real problems (lib.py, generator.py, brute.py)
• tests/fixtures/contest/toy/ — working toy problem for harness tests; imports lib from config/contest/templates/

• notion/tasks.pairs.json — production manifest (paths relative to private notion.task_root)
• tests/fixtures/notion/**/tasks.pairs.json — isolated test workspaces (not duplicates of config)
