Adds the bridge-connection-lifecycle signal that closes Prism's
~45s revoke window down to one server→client round-trip (~50ms).
Server (`@shade/inbox-server`):
- `inbox.peer_connected` / `inbox.peer_disconnected` events on the
0↔1 boundary across WS + SSE bridges. Long-poll deliberately not
tracked (every poll boundary would flap; push transports are also
the only ones where instant revoke matters).
- `PresenceTracker` collapses two parallel bridges (e.g. WS + SSE
during fallback handover) into one connect/disconnect pair.
- `GET /v1/bridge/presence` SSE endpoint: signed query with
`kind: 'presence'`, `watched: string[]`; on open streams a
per-address snapshot, then change frames filtered server-side.
MAX_WATCHED_ADDRESSES = 64. Subscribing does not itself count as
a peer-bridge connection.
- `createBridgeRoutes` now returns `{ app, websocket, presence }`.
Client (`@shade/transport-bridge`):
- `PresenceBridge.subscribe({ watch, onPresenceChange })` →
`{ addPeer, removePeer, watching, unsubscribe }`. addPeer/removePeer
mutate via reconnect with a fresh signed query.
- `signPresenceQuery` helper for non-PresenceBridge consumers.
Tests cover all four acceptance criteria from the Prism request:
server-event smoke, online→offline subscription, address scoping
(carol invisible to a [alice]-only sub), reconnect, plus an
addPeer/removePeer regression.

@shade/widgets
Embeddable React widgets for live Shade observability. Drop them into any React dashboard (Nova, Orchestrator, your own apps) to show what's happening in your Shade deployment.
Install
bun add @shade/widgets react react-dom
Quick start
import { ShadeProvider, IdentityCard, SessionList, RecentActivity } from '@shade/widgets';
function MyDashboard() {
return (
<ShadeProvider
observerUrl="https://shade.example.com/shade-observer"
token={process.env.SHADE_TOKEN!}
>
<IdentityCard />
<SessionList />
<RecentActivity />
</ShadeProvider>
);
}
You need a running @shade/observer endpoint for the widgets to talk to.
Components
| Component | Description |
|---|---|
<IdentityCard /> |
Your fingerprint, registration ID, init/rotation timestamps |
<SessionList /> |
Active Shade sessions with per-session message counts and DH ratchet steps |
<PrekeyStock lowThreshold={5} /> |
Gauge of remaining one-time prekeys with low-stock warning |
<RecentActivity limit={50} /> |
Live SSE feed of events flowing through the system |
<ServerStatus /> |
Prekey server stats (registered identities, fetches, replenishes, rate limits) |
<FingerprintCompare /> |
Paste a safety number to verify it matches your identity |
<WidgetCatalog /> |
Meta-widget letting users pick which widgets to display |
Letting users pick widgets
<ShadeProvider observerUrl="..." token="...">
<WidgetCatalog
available={['identity', 'sessions', 'prekeys', 'activity', 'server']}
defaultLayout={['identity', 'sessions', 'activity']}
/>
</ShadeProvider>
User selections persist to localStorage. Pass onLayoutChange to override with your own persistence.
Theming
<ShadeProvider observerUrl="..." token="..." themeMode="auto">
Modes: dark (default), light, auto (matches prefers-color-scheme).
Each widget renders self-contained CSS via inline styles — no Tailwind, no external CSS file, no conflicts with your host app.
Hooks
For custom layouts, use the underlying hooks directly:
import { useShadeState, useShadeEvents } from '@shade/widgets';
function CustomWidget() {
const { state, loading } = useShadeState();
const { events, connected } = useShadeEvents();
// ... render whatever you want
}
Polling interval
Default poll for /api/state is 5 seconds. Override:
<ShadeProvider observerUrl="..." token="..." pollIntervalMs={2000}>
The SSE event stream updates instantly regardless of poll interval.
