Conestoga Game Dev Skill

Quick Context

Code: src/conestoga/game/ (runner.py, gemini_gateway.py, events.py, state.py, ui.py, validators.py, fallback_monitor.py).
Entry: conestoga script or uv run python -m conestoga.main.
Tests: uv run pytest (CI defaults headless), headless toggle via UI_HEADLESS=1 or CI=1; set UI_HEADLESS=0 for visible window.
Make targets: make install-dev, make lint, make format, make test, make run.

Gemini & Fallback Rules

Only Gemini 3 models via GeminiGateway; offline/quota sets resource_exhausted.
Validator enforces 2–3 choices, unique IDs/text, and effect targets (allowed resources, catalog items).
FallbackMonitor tracks fallback source/reason; UI logs fallback/timeout; gemini_online flag controls offline badge.
Modify resources only via GameState.modify_resource (raises on unknown fields).

Testing

Run uv run pytest; optional SHACL test skips if pyshacl missing.
Scripts: scripts/test-pre.sh / scripts/test-post.sh (Docker opt-in via RUN_DOCKER=1, compose file docker-compose.test.yml, temp dir TEST_RUN_DIR).
Headless UI tests set UI_HEADLESS=1; use UI_HEADLESS=0 locally to view windows.

Key Files

Validation/fallback: src/conestoga/game/validators.py, fallback_monitor.py, gemini_gateway.py, runner.py.
UI: src/conestoga/game/ui.py (headless toggle, logging).
Tests: tests/test_game.py, tests/test_ui_headless.py, tests/test_audit.py, tests/test_ontology.py.
Docs: README.md headless note; ontology ontology/conestoga.ttl.

Patterns to Preserve

Prefetch-first events, on-demand resolutions.
Validate before mutation; fallback on validation/timeout/quota.
UI logs choices, outcomes, fallback usage.
