feat: Shade E2EE library — M1-M3 complete
Signal Protocol implementation with full X3DH + Double Ratchet:
- M1: Core types, CryptoProvider interface, KDF chain functions,
SubtleCrypto+noble/curves provider, MemoryStorage
- M2: X3DH key agreement (identity keys, signed prekeys, one-time
prekeys, bundle processing for both initiator and responder)

release(v4.0.0): Shade GA — V3.x consolidation + audit prep
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.

feat(container): M-Box 1-8 — stack-agnostic standalone Docker container
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

- Routes call touchIdentity on register, bundle fetch, replenish
- 4 new tests for the cleanup API
M-Box 2: Stale cleanup background task

- 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.

feat(files): @shade/files 0.3.0 — E2EE filesystem RPC primitive
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.
