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.

4.1.0's HTTP RPC for browsers capped at inline payloads (≤ 256 KiB).
4.2.0 unlocks streams: server queues outbound chunks + control
envelopes per peer, browser long-polls the queue. Browser-to-server
writes ride the existing /v1/transfer/<id>/chunk POST routes
unchanged.
For Dispatch this unlocks mod-jar uploads (50 MB) and world-backup
downloads (100+ MB) — the actual reason browser-side @shade/files
matters.
### New API
@shade/sdk:
- shade.transferQueueRoute(opts?) — Hono app with /queue +
/v1/transfer/* routes. Auto-configures the queue transport.
- shade.configureTransfers extended: transport + envelopeTransport
override slots; resolveBaseUrl optional when both supplied.
@shade/transfer:
- OutboundQueue — per-peer monotonic event log with long-poll
semantics, idle-eviction GC, ring-buffered to maxEventsPerPeer.
- QueueTransferTransport — enqueues instead of POSTing.
@shade/files:
- httpClient({ outboundQueueUrl, transferBaseUrl }) — when set,
starts a long-poll drainer + builds a streams-bridge. fs.read /
fs.write of >256 KiB work end-to-end.
- startQueueDrainer(shade, opts) — exported helper for advanced
consumers driving their own drainer.
### Implementation notes
- ClientStreamsBridge's TransformStream had HWM=0 by default which
stalled the drainer's await chain at chunk 4 (writer.write pended
before the consumer's reader was attached). Bumped to HWM=64 so
the receive loop can buffer ahead of the consumer.
### Tests
3 new integration tests in tests/integration/http-rpc-streams.test.ts:
4 MiB streamed read round-trip, inline-only error path, idle-timeout
long-poll behaviour.
Wire-compatible. Source-compatible. Lockstep bump to 4.2.0.

Default shade.files.client(peer) requires both peers to be mutually
addressable over HTTP — the response round-trips through
Shade.deliverControlEnvelope (POST to peer's /v1/transfer/control).
Browser tabs can't host an HTTP server, so they couldn't consume
@shade/files at all. Dispatch's filutforsker (admin-panel browser UI)
is the canonical use-case.
This release adds a parallel request-response transport: one POST per
RPC, encrypted envelope in the body, encrypted response in the same
HTTP response. No inbound channel needed on the client.
### New API
- shade.files.rpcRoute(opts?) — Hono app exposing POST /rpc.
- shade.files.httpClient(peer, opts) — request-response FileClient.
- FilesNamespace.serve(handler, { inlineOnly: true }) — skip streams-
bridge (and its configureTransfers pre-condition); also skip
channel-based dispatch so requests aren't double-dispatched.
### Limitations (v1)
Inline only (≤ 256 KiB). Streamed reads/writes throw clear errors
directing to shade.files.client(peer) on a server-to-server deploy.
### Tests
7 integration tests in tests/integration/http-rpc.test.ts covering
round-trip + negative cases (sender header, empty/garbage body,
maxBodyBytes, rpcRoute-without-serve).
### Symmetry
Mirrors @shade/server's shade-auth-middleware: encrypted envelope in
request body, decrypted via existing ratchet, response in same HTTP
roundtrip. No WebSocket, no SSE, no outbound from server.
Wire-compatible. Source-compatible. Lockstep bump to 4.1.0.

4.0.1's typecheck gate compiled each package internally against
lib: ["ES2022"]. That doesn't catch types that only fail when
*consumer* code (lib: ["DOM"] + exactOptionalPropertyTypes) tries to
assign a native browser type into one of our locally-defined narrower
types. Dispatch hit one such case in @shade/files inline-threshold.ts.
This release adds a tests/consumer-strict/ smoke project to the
pre-publish gate. It compiles a tiny "as if I were a downstream app"
TS file against:
lib: ["ES2022", "DOM", "DOM.Iterable"]
types: ["bun-types"]
exactOptionalPropertyTypes: true
strict: true
paths → packages/*/src/index.ts
scripts/typecheck-all.ts now runs the smoke after per-package checks.
Both must pass before publish:dry / publish:all proceeds.
### Fixed
- @shade/files inline-threshold.ts: MinimalReader<T> rewritten as the
explicit disjoint union { done:false, value:T } | { done:true,
value?: T | undefined } that's assignable from every native reader
shape (bun, DOM, node:stream/web). Fixes the
"ReadableStreamReadResult is not assignable" Dispatch reported.
- @shade/files streams-bridge (client + server): stash setTimeout
return in a local before .unref?.() via { unref?: () => void } cast.
Fluent .unref?.() failed under lib: ["DOM"] (setTimeout returns
number there).
- @shade/sdk background.ts: same setInterval .unref?.() fix.
Wire-compatible. No API shape changed.

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.

M-Files-1..6 land the full files-RPC layer + everything 0.3.0 needs to
ship. Apps keep their own UI; this layer ships the typed RPC, the
streams bridge for content I/O, and production hooks (rate limit,
retention, fingerprint gate, metrics).
@shade/files (NEW)
- Standard ops: list/stat/mkdir/delete/move/read/write/getThumbnail with
Zod-validated wire schemas + clean user-handler types.
- Custom ops: typed via TypeScript declaration merging on CustomOpsMap
+ per-op Zod schemas; client.custom('app.foo', {...}) is fully typed.
- Content I/O: inline (≤ 256 KiB plaintext) base64-in-RPC; streams
(> 256 KiB) ride @shade/transfer via userMetadata.shadeFilesWriteId
/ shadeFilesReadStreamId correlation. Server-side TransformStream
bridges accept inbound transfers immediately (engine rejects chunks
that arrive before accept) and park the readable for the matching
RPC.
- Directory ops: walk(path, opts) async-iterable depth-first walker;
uploadDirectory()/downloadDirectory() with bounded concurrency pool
(default 4, cap 16), aggregated progress, abort.
- Production hooks (callback-based, vendor-neutral): rate-limit (op +
byte), idempotency cache (LRU + TTL + in-flight de-dupe), path
policy (traversal + percent-decode hardening), fingerprint gate
(required/optional/reject), pluggable Ed25519 sig verification with
±5 min replay window, onMetric sink (standard names).
- React hooks (subpath @shade/files/react): ShadeFilesProvider,
useShadeFiles, useFileList, useFileTransfer/Upload/Download.
- Shade.files.serve(handler) + Shade.files.client(peer) high-level
entrypoint in @shade/sdk; lazy + memoized; one handler per Shade.
Wire format bump
- @shade/proto wire VERSION 0x01 → 0x02. Length prefixes changed from
u16 to u32. The previous u16 silently truncated payloads above
64 KiB — a hard correctness ceiling that blocked inline file ops
up to 256 KiB. Wire-incompatible with 0.2.x peers; new sessions
only. Cross-platform Kotlin port (android/shade-android) updated to
match; test-vectors/wire-format.json regenerated.
Concurrency safety
- ShadeSessionManager.encrypt/.decrypt now run under per-peer mutex.
Concurrent decryptions of the same peer raced ratchet state
(manifested as sporadic "Failed to decrypt — wrong key or tampered
data" under load — surfaced once concurrent uploadDirectory pumped
many writes in flight). Encrypt was already serialized via
Shade.send's encryptChains; decrypt is now serialized at the
manager layer too.
@shade/streams extension
- StreamMetadata.userMetadata?: Record<string, string> for
application-level key/value pairs that round-trip verbatim through
stream-init plaintext. Used by @shade/files for write/read
correlation; available to any consumer.
@shade/sdk extension
- Shade.files getter (lazy + memoized).
- BackgroundHooks.onPruneFiles + periodic timer (default 5 min) +
BackgroundTasks.setHook(name, fn) for runtime hook registration.
Bundles in-flight 0.2.0 work
- packages/shade-streams/, packages/shade-transfer/, related
shade-sdk streams-bridge + shade-widgets transfer hooks were
uncommitted prior to this session. Including them keeps the
workspace consistent at 0.3.0 since @shade/files depends on them.
Tests
- 74 new tests in @shade/files (572 → 646 workspace pass; 0 fail;
3× stable). Coverage spans unit (inline-threshold + concurrency),
integration (read-write inline + streams up to 1 MiB, walk +
upload/download directory, custom-op, metrics, SDK namespace
end-to-end), and security (tampered-envelope sig verification,
replay window, fingerprint gate, rate-limit + quota).
Release artifacts
- All packages bumped to 0.3.0 via scripts/bump-version.ts.
- scripts/publish-all.ts PACKAGES updated with shade-files in
topological order (after shade-transfer, before shade-sdk).
- bun run publish:dry clean (14 packed, 0 failed).
- examples/08-files-browser/ — three-process CLI demo (prekey + Bob
server + Alice CLI) covering list/stat/mkdir/delete/upload/download.
- docs/files.md — full API + design doc.
- CHANGELOG.md 0.3.0 entry.

Shade now ships as a self-contained Docker image. Deploy one container
per project, any stack (Bun, Python, Go, Rust, Kotlin) can talk to it via
plain HTTP. Zero coupling to consumer codebases.
M-Box 1: Stale identity cleanup API
- touchIdentity + purgeStaleIdentities on PrekeyStore interface
- Implemented for Memory, SQLite, and Postgres backends
- SQLite adds last_activity_at column with migration ALTER for existing DBs
- Postgres adds the same via raw SQL with IF NOT EXISTS guards
- Routes call touchIdentity on register, bundle fetch, replenish
- 4 new tests for the cleanup API
M-Box 2: Stale cleanup background task
- StaleCleanupTask runs purge on startup + every 24h (configurable)
- Reads SHADE_STALE_DAYS (default 30) and SHADE_CLEANUP_INTERVAL_HOURS
- Wired into standalone.ts, stopped on graceful shutdown
- 5 new tests for the task
M-Box 3: Observer baked into the container
- standalone.ts conditionally mounts @shade/observer at /shade-observer
when SHADE_OBSERVER_TOKEN is set (and >= 16 chars)
- Shared PrekeyServerEvents emitter feeds both routes and observer
- @shade/observer added as optional dependency of @shade/server
M-Box 4: Dockerfile with dashboard build
- Multi-stage build: oven/bun:1 builder → oven/bun:1-alpine runtime
- COPY packages/ wholesale so workspace lockfile resolves cleanly
- RUN bun run build inside shade-dashboard → dist/ → observer/dist/
- Non-root shade user, /data volume, healthcheck, env defaults
- Final image: 260 MB
M-Box 5: OpenAPI spec for stack-agnostic clients
- packages/shade-server/openapi.yaml documents all 9 endpoints with
request/response schemas, security (Ed25519 signatures + bearer token)
- createOpenApiRoutes serves /openapi.yaml and /docs (Redoc viewer)
- Any language can generate a client with openapi-generator
M-Box 6: Docker CI pipeline
- .gitea/workflows/docker.yml builds + pushes on git tag v*
- scripts/build-docker.ts for local builds, supports --push with GITEA_TOKEN
- Root package.json: build:docker, publish:docker scripts
M-Box 7: Deployment documentation
- packages/shade-server/README rewritten: 5-line quickstart with the image
- docs/DEPLOYMENT.md: full reference, env vars, backup, Dokploy, PG setup
- examples/05-dokploy-deployment/docker-compose.yml updated to pull
published image (gt.zyon.no/stian/shade-prekey:latest)
- Root README deployment section rewritten
M-Box 8: End-to-end verification
- Image builds locally (bun run build:docker)
- /health, /openapi.yaml, /docs, /metrics, /shade-observer all respond
- 401 without observer token, 200 with
- Real SDK client round-trip: Alice → container → Bob → reply → Alice
- Persistence: identity + prekeys survive container restart (count 20→18
as expected from two bundle fetches)
285 tests passing, 0 failures.

Phase D complete. Shade is now at parity with Signal libsignal's core
feature set.
M-Adv 1: Multi-device support (simplified Sesame)
- DeviceListManager tracks per-user device lists ("user:deviceId" addresses)
- fanOutEncrypt() sends one message to all known devices via independent
1:1 Double Ratchet sessions
- observeIncoming() auto-registers new devices from received messages
- JSON serialization for persistence
- userOfDevice/deviceIdOf address parsers
M-Adv 2: Backup and restore
- @shade/sdk exports BackupBlob format: version + salt + nonce + ciphertext
- Passphrase-derived key via HKDF (note: upgrade path to Argon2id documented)
- exportBackup()/importBackup() handle identity, prekeys, sessions, trust
- backupToString/backupFromString for single-string transport (copy/paste, QR)
- shade.exportBackup()/importBackup() convenience methods on SDK
- CLI: shade backup export <file> / shade backup restore <file>
- Rebuilds manager + transport after restore so ratchet state is consistent
M-Adv 3: Group messaging (Sender Keys)
- Per-sender chain key + Ed25519 signing key per group
- createSenderKey / buildDistribution / installDistribution for key distribution
- senderKeyEncrypt advances chain and signs ciphertext+header
- senderKeyDecrypt verifies signature then advances the sender's chain
- Out-of-order handling with bounded skip
- O(1) per message (once distributions are installed)
- Defensive ByteArray copies in distribution to prevent zeroize-across-refs
276 tests passing, 0 failures. All 13 SDK/tooling/platform/advanced
milestones complete. Shade is feature-complete for v2.0.

- shade doctor (diagnose config, storage, prekey server reachability)
- Config from .shaderc.json or SHADE_* env vars
Templates (in packages/shade-cli/templates/)
- bun-server — Bun + Hono backend with /send + /receive endpoints
- chat-demo — Two-process Alice/Bob chat over HTTP
Publishing pipeline (Gitea npm registry)
- .gitea/workflows/test.yml — CI on push/PR with PostgreSQL service
- .gitea/workflows/publish.yml — publish on git tag v*
- scripts/publish-all.ts — local publish helper with DRY_RUN support
- scripts/bump-version.ts — lockstep version bump across all packages
- Root package.json scripts: version, publish:dry, publish:all
Also: /health endpoint now lives in createPrekeyRoutes so doctor can
probe it without needing the full standalone setup.
Dry-run verified: all 11 packages pack cleanly.
246 tests passing, 0 failures.
