WEFT OS is a Wayland compositor and application runtime where every app is a WebAssembly component rendered in an isolated Servo WebView.

ipc.rs:
- Add SessionInfo { session_id: u64, app_id: String } struct.
- Change RunningApps { session_ids: Vec<u64> } to
RunningApps { sessions: Vec<SessionInfo> } so callers can display
meaningful app names without a follow-up QueryAppState round-trip.
- Add session_info_roundtrip test.
main.rs:
- Add SessionEntry { app_id: String, state: AppStateKind } to store
app_id alongside state in SessionRegistry.
- launch() stores app_id in the entry.
- running_sessions() replaces running_ids(); returns Vec<SessionInfo>.
- state() reads from SessionEntry.state.
- set_state() writes to SessionEntry.state.
- QueryRunning dispatch uses running_sessions().
- Test registry_running_ids_reflects_live_sessions renamed to
registry_running_sessions_reflects_live_sessions and updated to
assert both session_id and app_id fields.
- dispatch_query_running test asserts app_id values are present.
system-ui.html:
- RUNNING_APPS handler uses msg.sessions[].{session_id,app_id}.
- ensureTaskbarEntry(sessionId, appId): shows the last component of the
reverse-domain app ID as the taskbar label; sets data-app-id attribute;
tooltip shows full app ID and session number.
- LAUNCH_ACK handler passes null for appId (session ID only available
at launch time; app_id arrives in RUNNING_APPS on reconnect).

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
