Prism filed a per-recipient-flush-concurrency FR pointing at
serial-per-flush. Investigation surfaced the actual culprit:
`scheduleFlush` was using a 15 s backoff on **both** the success and
failure paths, so envelopes enqueued *during* an in-flight flush
sat ~15 s behind the next drain — visible as "10 s of silence then
25-frame burst" on the receiving side under sustained sender output.
Two fixes:
1. `scheduleFlush` now uses 0 ms delay when `flushOnce` delivered
≥1 envelope and more is queued (network healthy → drain
remainder immediately). 15 s reserved for the actual failure
case where every attempt this round failed. `flushOnce` returns
`{ delivered, remaining } | null` so concurrent-flush early
returns don't double-schedule.
2. `flushOnce` groups the outgoing queue by `recipientAddress` and
drains buckets via `Promise.all`. Per-peer order preserved
(sequential within a bucket); a slow POST to recipient A no
longer head-of-line-blocks frames bound for B.
`Inbox.tick` public shape unchanged. `OutgoingQueueStore`
implementations see the same per-entry list/remove/bumpAttempts/
size contract; only cross-recipient interleaving changes.
Tests cover (1) 25-envelope burst behind a 100 ms slow PUT drains
within 1 s, and (2) carol's PUT lands within 150 ms even when bob's
PUT stalls 200 ms.

@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.
