Summary

• skip mDNS advertisement for loopback-only server binds, avoiding unnecessary LAN broadcast work and Windows firewall prompts during local CLI runs
• make the Windows UIA worker back off while the shared screen-lock flag is set, and clear deferred UIA work while the desktop is inaccessible
• mark failed/invalid UIA capture attempts as attempted and avoid immediate wakeups when tree capture is disabled

Profiling

Pulled latest main, built target\release\screenpipe.exe, then profiled screenpipe record with audio/telemetry/keyboard/clipboard capture disabled while driving idle, app switching, typing, and scrolling phases.

Average CPU as % of one core:

The optimized run reproduced the OpenInputDesktop unavailable screen-lock state that previously caused high idle CPU, and stayed low. It also logged localhost server startup without the previous mdns: advertising line.
