voice_mode WSL playback probe, subagent_worktree._run_git, cua_backend
loginctl/xprop probes lost their explicit stdin= (and one line-wrapped past
the encoding= same-line rule); lazy_deps._run carries it via _SUBPROCESS_KW
so mark it for the guard. Fixes tests/tools/test_subprocess_stdin_guard.py
and tests/scripts/test_footgun_subprocess_encoding.py (green on base).
Real-profile browsing routes all in-page browser work through the Browser Use
CLI (browser_exec), which obsoletes the cua-driver typed-browser surface baked
into computer_use. Remove it so computer_use is a pure DESKTOP-control tool
(screenshots / mouse / keyboard / window management) and every call's schema
drops ~24 browser-only params + 9 actions.
- schema.py: 9 cua_browser_* actions and the typed-browser param block removed;
14 desktop actions + shared params kept; description drops the browser rung.
- tool.py: cua_browser entries out of _SAFE/_DESTRUCTIVE_ACTIONS; the whole
cua_browser dispatch block deleted; {"type","cua_browser_type"} → "type"
(desktop typing untouched); _config_preauthorized (browser-prepare-only, a
no-op for every desktop action) and the browser-page escalation hint removed.
- browser_route.py deleted (no importers outside the package); cua_backend.py
drops the import + typed_browser_* methods; backend.py drops the non-abstract
defaults.
- tests: browser-route/contract suites removed; browser assertions trimmed.
Desktop control unchanged. 233 computer_use tests pass; the 1 remaining failure
(test_gateway_session_key_yolo_maps_to_unrestricted_mode) is a pre-existing
cross-test state leak — fails identically on origin/main, passes in isolation.
Hardening on top of the TCC daemon-identity salvage:
- _validate_cua_driver_app_signature: codesign -dv gate requiring EXACT
Identifier=com.trycua.driver and the official team (4YEC26S9KF) before
/usr/bin/open hands the bundle to LaunchServices — the identity fix must
not double as a launcher for arbitrary/impostor bundles (suffixed
identifiers and wrong teams rejected; unsigned dev builds only via
computer_use.allow_unsigned_driver: true in config.yaml).
- _resolve_cua_driver_app_path: derive the bundle ONLY from the resolved
driver binary — the /Applications fallback could launch a DIFFERENT
install than the manifest resolved.
- open -n -g: don't activate/steal focus when launching the daemon.
- 7 new tests incl. sabotage-verified exact-match assertions.
Grafted from #76433's review direction (@Chadmc9889's original fail-closed
validation requirement).
