# Keep Automated Runs Out of the Foreground Tests and agent-driven app launches share the developer's machine. They may use it; they must never take the foreground — no window raised over the editor, no focus stolen, no Dock tile churn. `src/main/window/foreground-activation-policy.ts` enforces this in the main process. It is on whenever `ORCA_E2E_HEADLESS=1`, `ORCA_E2E_HEADFUL=1`, or `ORCA_BACKGROUND_LAUNCH=1`: - headless / explicit background → the window never reaches the screen (Playwright drives it via CDP) - headful without explicit background → `showInactive()`, no `app.focus({ steal: true })`, no `moveTop()`/always-on-top reinforcement - macOS headless / explicit background → `accessory` activation policy, so no Dock tile and no menu-bar takeover Rules when adding tests or scripts: - Launch through `tests/e2e/helpers/orca-app.ts` (or `orca-restart.ts`) — they already set the env. - A raw `electron.launch()` outside those helpers must pass `ORCA_BACKGROUND_LAUNCH: '1'`. - Do not reveal windows in explicit background or headless runs. Only an explicitly headful run may call `showInactive()`; never call `show()` or `bringToFront()` in automated background checks. - Tag a spec `@headful` only when it needs real pixels; it still runs in the background. - Native-focus tests belong on an isolated display or CI. Do not set `ORCA_E2E_FOREGROUND=1` on the user’s desktop; it cannot override explicit background mode. ## Isolated terminal performance presentation The Terminal Perf workflow has one explicit exception to the no-reveal rule: after windowless startup, `terminal-perf-presentation.ts` presents the benchmark window without focus on its isolated Xvfb display. Chromium otherwise throttles undrawn frames to one per second and makes typing measurements invalid. This exception requires all of: - `ORCA_E2E_TERMINAL_PERF_XVFB=1`, set inside `xvfb-run` by that workflow; - Linux, `GITHUB_ACTIONS=true`, `RUNNER_ENVIRONMENT=github-hosted`, and a nonempty `DISPLAY`; - the page fixture to finish loading before presentation, and confirmed native window visibility. Keep `ORCA_BACKGROUND_LAUNCH=1`: the application must still suppress automatic reveals and focus. `isWindowlessLaunch` describes that automatic launch policy, not the window's current visibility. This exception belongs only to this benchmark fixture; do not generalize it to local or self-hosted runs, paired-client helpers, native-focus tests, or production window policy. Background terminal panes remain hidden. Evidence: `docs/reference/terminal-perf-latency-investigation.md`.
