Servo Audit Backlog

This backlog maps WEFT requirements to the upstream audit and contribution work needed before WEFT can rely on Servo for system-shell and app-UI duties.

Rules

• No item is marked resolved without upstream evidence.
• A local workaround does not close an upstream dependency gap.
• Every audit item must end in one of: verified, upstream issue, local design adjustment, or blocked.

Backlog

Area	WEFT requirement	Current status	Next action	Exit condition
Wayland input	Shell-grade keyboard, pointer, touch, and IME behavior	Not verified in this repository	Audit Servo and winit behavior on Linux Wayland	Verified behavior or upstream issues filed for confirmed gaps
Wayland surface pipeline	Correct damage tracking, presentation timing, and buffer path behavior	Not verified in this repository	Audit Servo -> WebRender -> wgpu -> Wayland path	Explicit verification or upstream issue set
WebGPU completeness	Stable GPU app rendering path on Linux Mesa	Not verified in this repository	Compare Servo WebGPU coverage to WEFT needs	Verified required subset or upstream issue set
Multiprocess isolation	App UI crash isolation from shell UI	Known to be incomplete as a WEFT assumption	Audit Servo multiprocess and content-process behavior	Written gap assessment with next action
JavaScript runtime stability	Sufficient stability for system-shell and app UI JavaScript	Not verified in this repository	Audit current Servo main behavior and issue tracker	Verified risk record or upstream issue set
Accessibility	Linux AT-SPI readiness for shell and app UI	Not verified in this repository	Audit current AccessKit and Servo Linux path	Verified support state or upstream issue set

Local follow-up outputs expected from each audit

Each audit should produce:

• a reproducible environment description
• exact upstream revision or release under test
• observed result
• links to upstream issues if gaps are confirmed
• the WEFT planning consequence
