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 WasmServo 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
