Two unblocking changes for first-contact flows.
Sender attribution: relay captures shortHash(senderSigningKey) at
PUT time (after signature verification, no new trust surface) and
surfaces it on bridge push (IncomingMessage.from) + inbox-fetch
(FetchedBlob.from) + DecryptHandler raw arg. Apps receiving a prekey
envelope from a never-before-seen peer can now bootstrap X3DH via
shade.receive('fp:<hex>', env) — pre-4.8 the wire envelope didn't
authenticate the sender and there was no out-of-band hint to use.
Idempotent ALTER TABLE migrations for SQLite + Postgres add a
sender_fp TEXT column; legacy rows surface as from=undefined
(inter-version compat).
Inbox.start() race: pre-4.8 start() called register() fire-and-forget
AND schedulePoll(0) synchronously, so the first poll on a fresh
address often beat the register HTTP RTT and got SHADE_NOT_FOUND.
start() now defers; register() success kicks schedulePoll(0). Manual
tick() is unaffected (deliberate user action, no gating).
Both reported by Prism. Tests cover all five acceptance criteria
from the sender-attribution request (PUT capture, bridge surface,
fetch surface, inter-version compat, end-to-end pair smoke) plus
the three from the race-fix request.

@shade/transport-webrtc
V3.11 — direct peer-to-peer chunk transport for Shade transfers via
RTCDataChannel. Plugs into @shade/transfer's ITransferTransport
contract and wires automatically into @shade/sdk via
shade.configureWebRTC().
import { createShade } from '@shade/sdk';
import { nativeRtcFactory } from '@shade/transport-webrtc';
const shade = await createShade({ prekeyServer });
shade.configureWebRTC({ factory: nativeRtcFactory() });
shade.configureTransfers({ resolveBaseUrl });
await shade.upload({ to: 'bob', input: file }); // → P2P when NAT allows,
// HTTP otherwise.
See docs/webrtc.md for the full guide: NAT-traversal realities, TURN config, glare resolution, wire format, diagnostics, and end-to-end test recipes.
What's inside
WebRtcConnection— one peer connection between two Shade endpoints, driving offer/answer/ICE through Shade's own ratchet.WebRtcConnectionManager— per-peer pool with deterministic glare resolution.WebRtcSignalingChannel— JSON signaling messages multiplexed overShade.send/Shade.onMessage.WebRtcTransferTransport— implementsITransferTransportover the managed DataChannel; ack-correlated by 16-byte requestId tokens.MemoryRtcFactory— in-process WebRTC simulator for tests.nativeRtcFactory()— adapter overglobalThis.RTCPeerConnection(browsers / Deno / Cloudflare Workers).
Adapters
@shade/transport-webrtc ships only the standard-API adapter
(nativeRtcFactory). For Bun / Node, wrap your library of choice
behind the IRtcFactory interface — only createPeerConnection,
createDataChannel, and standard addEventListener are required.
