New discovery.rs browses _openclaw-gw._tcp with a lifetime mdns-sd
browser, keeps a fullname-keyed snapshot (resolved updates replace,
goodbye/TTL removes), and mirrors the native clients' TXT contract and
direct-selection gate (resolved SRV endpoint routing; tailnetDns is a
hint only). The bootstrap page lists discovered gateways and connecting
navigates the dashboard WebView to the resolved endpoint, validated
against the live snapshot; remote selection cancels the local watchdog
so an in-flight local bootstrap cannot steal the WebView back.
The desktop companion crate was Linux-only. All platform-specific code
lives in canvas.rs (WebKitGTK, cairo, unix sockets, SO_PEERCRED), so:
move webkit2gtk/cairo-rs/libc under linux target dependencies, gate the
canvas module, its protocol registration, invoke handler, and exit
shutdown to Linux, add a USERPROFILE home fallback and an explicit
no-op installer error for Windows, and add the multi-size icon.ico
Windows resource. Linux behavior is unchanged; macOS/Windows builds are
for testing (macOS cargo build+test green locally; Windows aarch64-msvc
built and launched in a Windows 11 ARM VM).
* feat(linux): canvas via CLI-node + Tauri app IPC bridge
* refactor: extract gateway helper modules
* build(linux-canvas): register plugin package in lockfile
* fix(linux-canvas): move canvas advertise test out of core, regen docs/protocol/deadcode
* fix(gateway): break node-catalog/registry import cycle via leaf normalize module; add canvas glossary term
* style: oxfmt invoke.ts and runtime.ts after buildNodeEventParams extraction
* fix(linux): load Canvas WebView via dedicated data_directory context
Wry's Linux/WebKitGTK incognito mode discards Tauri's registered
WebContext (wry webkitgtk/mod.rs), so the Canvas window got a fresh
ephemeral context without the openclaw-canvas:// scheme handler — the
bundled A2UI page never committed (stayed about:blank) and every A2UI
command timed out. Use an isolated cache-backed data_directory instead,
which keeps the protocol handler while still isolating Canvas storage
from the dashboard window.
* fix(linux): keep Canvas WebView ephemeral via incognito + data_directory
Autoreview flagged that a dedicated data_directory alone persists Canvas
browser state (cookies, localStorage, IndexedDB, service workers) across
restarts, so an agent that navigates Canvas to a site could leak an
authenticated session into a later session. iOS uses a non-persistent
store; Linux should match.
Add .incognito(true) alongside .data_directory(): the distinct directory
gives Tauri a fresh WebContext key so it still attaches the
openclaw-canvas:// protocol closure, and incognito makes Wry swap in a
fresh *ephemeral* context carrying those protocols. Live-verified on a
Wayland/WebKitGTK box: the bundled page still loads
(location.href=openclaw-canvas://localhost/index.html, openclawA2UI
present, A2UI renders) and the canvas-webview dir holds no persistent
cookie/storage files.
