LMOS VOID Beta 0.34.7: Windowed App Hardening, Safer Multi-Desktop State, and Render Certification
LMOS tightens the shared desktop contract: Device Lab no longer nests a second OS shell, multiple LMOS windows coordinate restore-state writes, windowed apps inherit an edge-to-edge surface contract, and Product Certification now includes a rendered desktop runner for every active app.
Pain point → fix → benefit
Device Lab could render LMOS inside LMOS → previews now force windowed mode → responsive checks exercise the app surface rather than a duplicate shell.
Two open LMOS desktops could overwrite one shared restore record → focused-instance writer coordination plus per-window session storage → background desktops stop fighting over continuity.
Apps could technically follow the window runtime while still looking like centered web pages → the desktop contract now includes shared edge-to-edge window chrome → app-specific work fills the window without another website frame.
A declared desktop contract could be mistaken for proof → Product Certification now has an explicit rendered app runner → every active app must earn evidence across the same ten window behaviors.
What remains manual
Rendered desktop certification is intentionally not auto-passed. It still requires real-browser evidence for each active app, especially resize breakpoints, fullscreen behavior, focus, app-specific controls and session continuity.
Use the beta on real work.
