feat(observer): M-Obs 4-7 — widgets, dashboard, docs, integration example
M-Obs 4: @shade/widgets React library
- ShadeProvider context with observer URL + token + theme
- useShadeState (polling) + useShadeEvents (SSE) hooks
- 7 widgets: IdentityCard, SessionList, PrekeyStock, RecentActivity,
  ServerStatus, FingerprintCompare, WidgetCatalog (meta-widget for
  user-selectable layout with localStorage persistence)
- Self-contained CSS via inline styles, no external CSS conflicts
- Light/dark/auto theme via tokens

M-Obs 5: @shade/dashboard standalone SPA
- Vite + React app composing all widgets into a full debugger layout
- Login screen with token persistence to localStorage
- Build script copies dist/ to @shade/observer/dist/ for embedded serving
- 211 KB JS bundle (66 KB gzipped)

M-Obs 6: Documentation + integration example
- READMEs for @shade/observer and @shade/widgets
- examples/06-observer-dashboard runnable demo: spins up prekey server +
  observer, runs Alice ↔ Bob conversation loop, dashboard at :3901
- Updated root README and docker-compose.yml with observer integration

M-Obs 7: End-to-end verification
- StateAggregator now drains buffered events on subscription, so
  identity.initialized fires before observer construction are still seen
- Verified live: snapshot endpoint returns full state, dashboard serves,
  401 without auth, sessions/messages/ratchet steps all tracked

220 tests passing, 0 failures.

# @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
```bash
bun add @shade/widgets react react-dom
```
## Quick start
```tsx
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`](../shade-observer/README.md) 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
```tsx
<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
```tsx
<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:
```tsx
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:
```tsx
<ShadeProvider observerUrl="..." token="..." pollIntervalMs={2000}>
```
The SSE event stream updates instantly regardless of poll interval.
