Pull-mode httpClient + drainer + parallel RPCs against the same peer deteriorated after ~10s with `DecryptionError`. Two bugs combined: - `OutboundQueue.enqueue` woke `drain` waiters with a `since=0` snapshot, replaying already-processed events into `Shade.acceptTransferEnvelope` → `manager.decrypt` twice. The duplicate consumed an already-used skipped key and corrupted the Double Ratchet receive chain. - `ratchetDecrypt` then propagated the corruption: a same-DH message behind the chain with no cached skipped key fell through to `kdfChainKey` on the ahead state and rewound `chain.counter`, permanently desyncing the chain. Fix `OutboundQueue` to honor each waiter's `since`, and harden `ratchetDecrypt` so any future duplicate fails cleanly without mutating state. Adds regression coverage at all three layers.

@shade/transport-bridge
Transport-agnostic delivery for Shade: WS → SSE → long-poll, in priority
order, behind a single IncomingMessage interface.
import {
FallbackBridgeTransport,
WsBridge,
SseBridge,
LongPollBridge,
} from '@shade/transport-bridge';
const auth = { crypto, signingPrivateKey, address: 'bob' };
const bridge = new FallbackBridgeTransport([
new WsBridge({ baseUrl, auth }),
new SseBridge({ baseUrl, auth }),
new LongPollBridge({ baseUrl, auth }),
]);
await bridge.connect({
onMessage: (msg) => {
// msg: { from: string; bytes: Uint8Array; receivedAt: number; msgId?: string }
},
});
console.log(bridge.activeKind); // "ws" | "sse" | "long-poll"
Pair with createBridgeRoutes in @shade/inbox-server to expose the
matching /v1/bridge/{stream,poll,ws} endpoints. Full design + threat
model in docs/transport.md.
What it solves
Browser extensions, strict corporate proxies, and edge runtimes routinely block long-lived WebSockets. Apps that already use the Shade inbox shouldn't have to write three custom delivery paths to handle the realistic mix of hostile networks they ship into. This package is the canonical answer.
Status
V3.7. Stable wire format, additive change to @shade/inbox-server. See
CHANGELOG.
