Three new wires from page to shell and back, proving the bridge end to
end. The dashboard placeholder now follows the system color-scheme via
the full chain: page-side dashShell.call('getTheme') → WebKit script
message handler → DBus method on the shell-owned service → gsettings
read → return value back up. ThemeChanged proves the reverse direction:
the shell watches color-scheme and emits a DBus signal that the
container forwards to the page as a CustomEvent.
extension/src/dbus-service.ts
Owns top.hangmanlab.Dashward.Shell on the session bus; exports
GetTheme (reads org.gnome.desktop.interface::color-scheme, maps
prefer-dark→dark / else→light); emits ThemeChanged on the gsettings
changed signal. Bus acquisition is async, so the constructor takes an
onReady callback that fires from the bus_acquired handler.
extension/src/extension.ts
Sequencing: warden → guard → dbus, and only after dbus_acquired
callback fires do we spawn ContainerSupervisor. Disable order is
reversed (container first so its DBus proxy stops calling the service
before we unown the bus name).
container/src/dbus-client.ts
Thin GJS proxy wrapper around the Shell interface; exposes a typed
getTheme() / onThemeChange(cb) API.
container/src/bridge.ts
Registers a `shellCall` UCM script-message handler; parses
{id, method, args} JSON from the page, dispatches to invoke(), and
feeds the result back via evaluate_javascript. Shell signals are
forwarded to the page via window.__dashShell__._onSignal.
container/runtime/runtime.ts
Installs window.__dashShell__ at script start, calls getTheme() on
load and applies the result to <html data-theme>, listens for the
ThemeChanged CustomEvent.
container/runtime/dashboard.html + esbuild.config.js
Switched the runtime bundle from `format: 'esm'` to IIFE so it loads
as a classic <script> -- WebKitGTK silently refuses `<script
type="module">` over file:// for ES module resolution. Added an
inline error catcher that surfaces JS errors in the visible boot
diagnostic div instead of failing silently.
container/src/main.ts
Construct ShellClient + Bridge before load_uri so the very first
page-side dashShell.call() has a handler waiting. Added load-changed
/ load-failed signal logging for future diagnosis.
Verified on ubuntu2504-test VM: enable produces clean log chain through
"container window arrived", page renders with "P4 — shell bridge
online" placeholder and the correct system theme on first paint, manual
`gsettings set ... color-scheme prefer-dark` flips the placeholder
background live.

Dashward now actually renders content on the dashboard workspace. The
container is a separate gjs subprocess (so a WebKit crash can't take
down gnome-shell), and the extension pins its window to the dashboard
slot via the WindowGuard whitelist.
container/src/main.ts: tiny GJS bootstrap that creates a borderless
fullscreen Gtk.Window with a WebKit2 WebView and loads dashboard.html
from a runtime directory passed in via argv. `GLib.set_prgname` happens
before any GTK init so Wayland's xdg-shell app_id matches
`top.hangmanlab.dashward.container` -- that's the wm_class fingerprint
the extension matches against.
extension/src/container-supervisor.ts: spawn the container via
Gio.Subprocess; pump its stdout/stderr into journal under `[container
stdout|stderr]` tags so we can diagnose WebKit crashes without
attaching; watch display::window-created for the app_id match; on
arrival, whitelist with WindowGuard before moving to dashboard (so the
move's window-added doesn't bounce); make_fullscreen; clear the cached
ref on the window's `unmanaged` signal. Dispose SIGTERMs the
subprocess. P3 explicitly skips auto-restart / exponential backoff and
DBus signaling -- those land in P4.
container/runtime/runtime.ts + styles.css: a "Dashward" placeholder
card on the 12-column grid so the dashboard workspace is visually
distinct from a regular workspace; widget mounting / edit mode is P5+.
Verified on the ubuntu2504-test VM: extension enables cleanly, dashboard
shows the placeholder, switching to/from dashboard works, ding's window
is still ignored. MESA/EGL stderr lines are VM-only software-rendering
fallback noise (no virgl).

Bootstrap the Dashward repo per arch/UBUNTU-DASHBOARD-SPACE.md:
- pnpm-workspaces monorepo (sdk, extension, container, widgets-builtin/*)
- GNOME extension stub (metadata.json, src/*.ts placeholders for warden,
guard, supervisor, entry UX, DBus service)
- WebKit container stub (GJS main + page-side runtime + dashboard.html)
- TypeScript widget SDK (defineWidget + types)
- Builtin clock widget as the first SDK consumer example
- DBus interface XML (proto/shell.iface.xml) and shared types
- esbuild configs for extension and container; tsc for SDK
- Design doc copied in at repo root for discoverability
No functional logic yet -- all components are placeholders that compose
in extension.ts so the build chain can be exercised. P1 (workspace
warden) starts next.
