Marco Allegretti 18f92cc341 feat(compositor): implement weft-shell-protocol server side 
Add the WEFT compositor-shell Wayland protocol and wire it into the
compositor state.

Protocol definition:
- protocol/weft-shell-unstable-v1.xml: defines zweft_shell_manager_v1
  (global, bound once by servo-shell) and zweft_shell_window_v1
  (per-window slot). Requests: destroy, create_window,
  update_metadata, set_geometry. Events: configure, focus_changed,
  window_closed, presentation_feedback.

Generated code + bindings:
- crates/weft-compositor/src/protocols/mod.rs: uses wayland-scanner
  generate_interfaces! inside a __interfaces sub-module and
  generate_server_code! at the server module level, following the
  wayland-protocols-wlr crate structure. Exports WeftShellState
  (holds the GlobalId) and WeftShellWindowData (per-window user data).

Server-side dispatch (state.rs):
- GlobalDispatch<ZweftShellManagerV1, ()>: binds the global, inits
  each bound resource with unit user data.
- Dispatch<ZweftShellManagerV1, ()>: handles create_window by
  initialising a ZweftShellWindowV1 and sending an initial configure.
- Dispatch<ZweftShellWindowV1, WeftShellWindowData>: handles
  update_metadata (stores advisory data) and set_geometry (echoes
  compositor-adjusted configure back to client).

WeftCompositorState.weft_shell_state initialised in new() alongside
all other protocol globals.

New direct deps in weft-compositor: wayland-scanner, wayland-server,
wayland-backend, bitflags (all version-matched to Smithay 0.7).

README.md

WEFT OS

WEFT OS is a Linux-based operating system effort built around a Smithay compositor, a Servo-rendered system shell, and a Wasmtime-based application runtime.

Current repository scope

This repository currently contains:

  • the baseline Rust workspace
  • public engineering documentation derived from the authoritative blueprint
  • initial design documents for the shell protocol boundary and the Wasm–Servo channel
  • local and CI validation paths for repository bootstrap work

It does not yet contain a compositor, shell, or application runtime implementation.

Source of truth

The authoritative technical reference for this repository is docu_dev/WEFT-OS-COMPREHENSIVE-BLUEPRINT.md.

Historical blueprint documents exist in docu_dev/, but they are not implementation authority where they conflict with the comprehensive blueprint.

Privacy boundary

docu_dev/ is a private coordination area used during development. It is intentionally ignored by git and is not part of the tracked public repository surface.

Development model

  • Primary development host: Windows workstation
  • Primary runtime target: Linux VM or QEMU guest
  • Core system language: Rust

Validation

On Windows PowerShell:

./infra/scripts/check.ps1

On Linux:

./infra/scripts/check.sh
