_PY_SKIP includes apps/, so a change to apps/shared/src/gateway-events.json
(or apps/desktop/src/lib/desktop-slash-registry.json) alone classified as
python:false and tests/tui_gateway/test_gateway_event_contract.py — the
only side that checks emitters against the JSON — never ran. "Either side
drifting turns both red" was true locally and false in CI for that
direction. A table of cross-language contract files now forces python:true
alongside frontend; two classifier rows pin it (they fail without the
allowlist).
