Two follow-ups to the V4.8.2 duplicate-fan-out fixes Prism filed.
1. `Inbox.acceptBridgeFrame(blob)` + shared 4096-entry msgId LRU.
The relay durably stores blobs and pushes them to every active
delivery channel; without a cross-channel ack the bridge frame
ran first and the next inbox-poll re-dispatched the same blob
~30 s later, tripping on consumed prekeys. Bridge consumers now
plumb pushed frames through `acceptBridgeFrame`, which shares
the dedup gate + ack path with `pollOnce`. Whichever channel
delivers first wins; the other acks-and-skips. Inbox records
the msgId before the ack so a parallel poll can't observe an
in-flight ack window.
2. `Shade.aliasSession(oldLabel, newLabel)`. First-contact forces
the receiver to label the new session by the relay's sender
fingerprint hint (`fp:<senderfp>`); the post-decrypt plaintext
typically announces the peer's real address. Aliasing moves
session, trusted identity, peer-verification, and identity-
version under the canonical label. Holds the per-peer mutex on
both labels (lexicographic order) so concurrent crypto ops can't
observe a half-moved state. Refuses to overwrite an existing
session at the new label.
Wire change: `IncomingMessage.expiresAt?` now surfaces the relay's
expiry so receivers can pass bridge frames straight to
`acceptBridgeFrame` without inventing a TTL.
Tests cover bridge-then-poll, poll-then-bridge, aliasSession happy
path, refuse-to-overwrite, and same-label no-op.

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.

Browsers' Window.fetch is a WebIDL bound operation; storing it as
this.fetchImpl / this.fetchFn and calling via the instance receiver
threw "Illegal invocation" on the first request. Bind once at
construction in InboxClient, LongPollBridge, and SseBridge. Reported
by Prism (multi-device E2EE terminal), blocking every browser
consumer of the v4.6 transport stack on inbox.start() / bridge.connect().
WsBridge unaffected (uses WebSocket). Node/Bun fetch tolerates a free
receiver, so the bug never surfaced server-side — added regression
tests that install a strict-receiver globalThis.fetch to catch the
issue without an actual browser harness.

4.0.0 shipped TypeScript source as published main/types, but several
files only compiled inside the monorepo. Consumer projects (Dispatch,
etc.) running their own strict tsc against our published source hit:
- @shade/key-transparency: 4 noUnusedLocals violations
(IndexAbsenceProof, IndexInclusionProof, IndexProofWire, nodeHash)
- @shade/sdk: KT verifier callbacks returned Promise<unknown> instead
of Promise<STHWire> / Promise<{ proof: string[] }>
- @shade/sdk: thumbnail.ts globalThis cast collided with consumer's
lib.dom-supplied createImageBitmap signature
- @shade/files: cycle with @shade/sdk produced "this is not assignable
to type 'Shade'" because hoisted node_modules layouts duplicated the
Shade class. Broken by replacing `import type { Shade }` with a
local structural ShadeBridge interface.
- @shade/storage-encrypted: KeyUsage (lib.dom) used under
lib: ["ES2022"]
- @shade/transport-bridge: ReadableStreamDefaultReader<any> ↔
<Uint8Array> mismatch
- @shade/keychain / @shade/dashboard / @shade/storage-encrypted
tsconfig rootDir / include hygiene
Tooling: scripts/typecheck-all.ts runs `bunx tsc --noEmit` against
every workspace package's tsconfig and fails on any error. Wired into
publish:dry / publish:all and publish-shade.sh as a hard gate so this
class of bug cannot recur.
All 24 packages bumped to 4.0.1 in lockstep.
Migration: <ShadeFilesProvider> now requires an explicit `files` prop
(pass `shade.files`). Wire format unchanged.

V3.1 → V3.12 consolidated and tagged for the first GA release. Wire
format unchanged from 0.4.x — 4.0 peers interoperate with 0.4.x peers
byte-for-byte. The version bump is semantic: audit-cycle complete,
opt-in surface fully exposed, threat model refreshed for every new
surface.
Highlights:
- All 24 @shade/* packages bumped to 4.0.0 in lockstep.
- CHANGELOG 4.0.0 section is the canonical manifest of what landed.
- THREAT-MODEL extended (§10 fingerprint gates, §11 WebRTC P2P, §12
Web-Worker boundary) + residual-risks table refreshed.
- OpenAPI now covers all 27 routes: prekey, transfer, KT, inbox,
bridge, observer, /metrics, /healthz, /ready.
- MIGRATION 0.3.x → 4.0 documented + smoke-tested against
shade migrate-storage on a real SQLite DB.
- docs/audit/REVIEW-BUNDLE.md + SCOPE.md ready for external reviewer.
- scripts/soak.ts harness for the GA-stable 2-week soak window.
- All V*.md plans archived under docs/archive/ with Status: Done.
- Voice/Video carved out into V5.0; 4.0 audit focuses on the frozen
non-realtime stack.
Tests: TS 1000/1000 + Kotlin 11/11 cross-platform vectors green.
Docker: gt.zyon.no/stian/shade-prekey:4.0.0 builds and reports
version 4.0.0 on /health.
