aliasSession knew that two labels name the same peer, then threw that
knowledge away. The binding lived only in the caller's memory, so a
restart lost it — and the peer could not repair it from its side.
First contact forces the receiver to label a session by the only sender
hint a relay surfaces, an 8-byte signing-key fingerprint (`fp:<hex>`).
Once the peer announces its canonical address, aliasSession moves the
session there. But the peer keeps sending under `fp:<hex>`, because its
transport derives the same label from the same hint every time. After a
restart the session sat under the canonical address, inbound frames
resolved to `fp:<hex>`, and nothing matched. The peer held a valid
session so it never re-ran X3DH: the failure was permanent, and only a
manual re-link cleared it.
Observed in Prism as `No session for address: fp:579c3b335d66e2c0` on
every receive for three days, with a phone whose every RPC timed out.
StorageProvider gains saveSessionAlias / getSessionAlias /
removeSessionAliasesFor, optional so third-party implementations keep
compiling, and implemented across all seven backends. Lookups resolve
through resolveLabel(), which runs BEFORE the peer mutex — locking the
alias while mutating the canonical session would let an aliased and a
canonical caller ratchet the same state concurrently.
A live session under a label always wins over an alias, and prekey
envelopes never resolve: both keep a re-link establishing a fresh
session instead of being redirected into the stale one. Aliases are
dropped in resetSession and acceptIdentityChange, and memoized so the
hot path costs no extra read.
The sdk.test.ts case that asserted a dead fp-label encoded the old
behaviour; it now pins the new contract.
Verified: 1166 tests pass (from 1160). With alias persistence disabled
as a negative control, 5 of the 6 new tests fail, including both
restart cases.
Also drops `baseUrl` from the consumer-strict tsconfig — removed in
TS 6.0, and it was failing the typecheck that gates publishing.

publish-all.ts now does a tsc → dist/ build per package before pack, then
rewrites package.json's main/types/exports to point at the built artefacts
and ensures `files: ["dist"]` so the tarball ships only the built code.
The in-repo package.json is restored in the finally block so dev/typecheck
keep working without a build pass.
Why: strict-mode consumers (Cyndr) were forced to recompile Shade source
under their own tsconfig and tripped on internal `process.env.X` accesses
and implicit-any parameters. Shipping pre-built `.js` + `.d.ts` makes the
strictness contract live entirely inside Shade.
Builds on V4.9's encrypted profile blob: ships the canonical
profile-blob schema (hosts/clients/trustedApproverFingerprints) and
the build/sign/verify trio for proxy-approval frames. Headless servers
can now route a `linkRequest` to a trusted-approver phone, verify the
phone's Ed25519 signature against the fresh profile blob, and complete
pairing without a GUI host being available.
Length-prefixed binary signing payload so any platform (Kotlin, Swift,
Go) can produce byte-identical signing input from test vectors. No
relay or transport changes — entirely SDK-level.

Ships the Prism FR (encrypted-profile-storage-v4.9.md) as a generic
relay-side encrypted blob primitive: deterministically-located,
AEAD-sealed blobs keyed by a 32-byte slotId derived client-side via
HKDF from the user's master key. Unlocks credential-only bootstrap
of new devices into existing E2EE state — no QR, no physical access.
Server: BlobStore interface + Memory/Sqlite/Postgres impls,
createBlobRoutes for GET/PUT/DELETE /v1/blob/:slotId with TOFU pubkey
auth and If-Match CAS (409/412 semantics). Mounted on the same Hono
app as the inbox; SHADE_BLOB_PG_URL / SHADE_BLOB_DB_PATH /
SHADE_DISABLE_BLOB env-var plumbing in standalone.
SDK: createProfileNamespace high-level wrapper (HKDF derivation,
random-nonce AEAD seal, slotId-bound AAD) + low-level BlobClient.
Cross-platform test vectors in test-vectors/blob-storage.json.
New errors: ConflictError (409), PreconditionFailedError (412).

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.

V4.8.3 shipped client-side cross-channel dedup hook
(`Inbox.acceptBridgeFrame`), but recipients that didn't migrate to
the new wiring still observed the same envelope twice — once via
WS bridge push, again ~30 s later via inbox-poll. Prism re-verified
the FR after 4.8.3 and asked for a relay-side enforcement so app
code doesn't have to ack-via-DELETE on every bridge frame.
V4.8.4 adds an in-memory `BridgeDeliveryLog` (default 60 s grace,
8192-per-address cap) that records every successful WS / SSE /
long-poll push of `(address, msgId)`. The `/v1/inbox/:addr/fetch`
route filters out blobs in the log's grace window so a recipient
running both a bridge and the 30 s poll cadence sees exactly one
delivery. Cursor advances over the full fetched window so a poll
that straddles a suppressed blob doesn't stall.
The standalone server auto-wires the log between
`createBridgeRoutes` and `createInboxRoutes`. Custom mounts thread
the same instance through `bridgeDeliveryLog` on both factories.
Tests cover WS-then-poll, SSE-then-poll, and a negative control
(non-bridge-pushed blob still comes through inbox-fetch).

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.

Two interlocking robustness fixes for the duplicate-fan-out / first-contact
class of failures Prism reported.
1. `Shade.receive(from, env)` now queues its `manager.decrypt` step
per `from` so concurrent dispatches can't race the SessionManager
ratchet or the StorageProvider (sqlite "database is locked", IDB
transaction conflicts). User message handlers run *outside* the
queue so streams + file-RPC's nested `shade.receive` calls don't
self-deadlock.
2. Bridge WS + SSE handlers now run a per-connection bounded msgId
LRU as defense-in-depth against any flushTo re-entry (event-storm,
future refactor). Pending-flush chains are wrapped in `.catch(() =>
{})` so a transient `ws.send` rejection no longer poisons the
connection's flush loop.
Tests: storming `inbox.blob_stored` 10× per PUT yields exactly one WS/
SSE frame; 8 concurrent `bob.receive('alice', envelope)` calls keep
the ratchet intact and never surface "database is locked".

Plumbing fix only — both createPrekeyRoutes and createInboxRoutes
already accepted disableRateLimit; standalone.ts just didn't read
the env. Now SHADE_DISABLE_RATE_LIMIT=1 turns off IP rate-limits on
every prekey + inbox route, with a WARN log on startup so operators
see it.
Single-tenant deployments only — multi-tenant relays must leave it
unset. Documented in docs/DEPLOYMENT.md.
Reported by Prism: ~6 pair attempts/hour from a single dev IP +
the sidecar's register call tripped the 5/hour REGISTER_LIMIT every
dev iteration.

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.

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.

Lands the broadcast-channel primitive Prism asked for in
Docs/shade-feature-request-sender-keys.md. The crypto in
@shade/core/sender-keys.ts was already in place; this release wires
it up as a first-class app-facing API, adds the persistence schema
across all six storage backends (memory, sqlite, indexeddb +
encrypted variants), introduces wire type 0x21 in @shade/proto,
and ships Prism's three acceptance tests verbatim.

Adds the foundations Prism's web client (and any future browser-based
Shade app) needs: at-rest-encrypted IndexedDB storage that mirrors the
SQLite backend byte-for-byte at the AAD/nonce level, browser-safe
subpath imports so Vite/webpack/esbuild stop hitting bun:sqlite, and
KeyManager support for argon2id and N-factor composite unlock.
@shade/storage-encrypted
- EncryptedIndexedDBStorage (subpath: /idb) — full StorageProvider
using one object store per _enc table; reuses aeadSeal/aeadOpen +
row-codec sealers so a row sealed under the SQLite or Postgres
backend decrypts under IDB given the same KeyManager.
bumpPeerIdentityVersion is atomic under one IDB transaction.
- KeyManager argon2id source — memory-hard KDF for low-entropy
secrets (PINs). Backed by @noble/hashes/argon2 (already a transitive
dep). DEFAULT_ARGON2ID exported (m=64 MiB, t=3, p=1).
- KeyManager composite source — HKDF-combine N sub-sources into one
master. Every source mandatory; order significant by design;
composite-of-composite rejected; optional info string for app-level
domain separation.
- Subpath exports (/crypto, /sqlite, /postgres, /idb) plus a `browser`
condition on the default import that resolves to a barrel
excluding the Bun- and Postgres-specific entries. Browser bundles
no longer pull bun:sqlite transitively.
Tests
- 73 tests in shade-storage-encrypted (was 31). New coverage:
argon2id determinism + reject paths, composite same-factors → same
master, wrong-PIN/passphrase/order-swap → different master, info
domain separation, all 28 StorageProvider methods on
EncryptedIndexedDBStorage, fingerprint-mismatch rejection, and
cross-impl roundtrip with EncryptedSQLiteStorage proving the AAD/
nonce derivation is implementation-agnostic.

Expose the local device's 32-byte Ed25519 identity public key on Shade
so apps can hand it to their own backend at enrollment time for
signature verification, key pinning or per-device safety-number
computation. Closes the gap that forced consumers to ship placeholder
random bytes their backend could store but never verify against.
- @shade/sdk Shade.identityPublicKey: Promise<Uint8Array> — getter
mirrors the existing fingerprint accessor. Throws pre-init,
reflects the current key after rotate(), retired key preserved in
retired-identities storage per existing grace-period contract.
Private key remains unreachable.
- Test in shade-sdk/tests/sdk.test.ts: round-trip match against the
underlying storage's signingPublicKey, plus value updates after
rotate().
- Lockstep version bump 4.3.0 → 4.4.0 across all 25 packages.

Ship an official IndexedDB-backed StorageProvider so browser-based Shade
consumers persist identity, prekeys, sessions, retired identities,
peer-verification state and stream-resume rows across tab refresh and
browser restart. Closes the gap that forced browser apps onto
storage:"memory" (regenerated identity each load, orphaned device
records server-side).
- New package @shade/storage-indexeddb (4.3.0): full StorageProvider
conformance, schema v1, idb-backed; bumpPeerIdentityVersion is wrapped
in a single readwrite IDB transaction (atomic, vs SQLite's
read-then-upsert race).
- @shade/sdk resolveStorage() accepts { type: 'indexeddb', dbName? } via
dynamic import (lazy, optional dep — same pattern as
@shade/storage-postgres). Named StorageSpec type now reused by
ResolvedConfig.
- Tests: 16 new tests in shade-storage-indexeddb (StorageProvider
surface + peer-verifications + full E2EE conversation surviving a
simulated tab reload). Run on fake-indexeddb.
- Lockstep version bump 4.2.1 → 4.3.0 across all 25 packages.
- Publish scripts updated to include the new package.
