### Major changes
- **Client-side identity** — New session key store (`sessionKey.ts`) backed by
`sessionStorage` with a module-level caching, a `crypto.subtle` cache, a `useIdentityLock`
hook for decrypt-once signing, `followSignature.ts` for signed follows, and
two new UI modals (`IdentityBackup.tsx`, `UnlockIdentityModal.tsx`).
`CreateIdentity.tsx` is rewritten to generate BIP-39 mnemonics and encrypt the
Ed25519 keypair with AES-256-GCM via PBKDF2 (600k iterations) before storing
in IndexedDB.
- **Rate limiting** — New `rate-limit-config.ts` and `rate-limit.ts` provide a
per-IP sliding-window rate limiter backed by Redis. All external-facing routes
(`/discover`, `/discover/rotate/*`, `/proxy`, social API endpoints) now have
conservative defaults wired into the custom HTTP server before requests reach
Next.js handlers.
- **Proxy route hardening** — The `/proxy` route now enforces a 256 KB payload
limit (HTTP 413), validates JSON before parsing, applies a per-origin rate
limit (100 req/min), and imports the `blocks` table to reject requests from
blocked servers.
- **Docker integration-test cluster** — New `Dockerfile`, `.dockerignore`, and
`tests/docker-compose.yml` orchestrate three SiPher instances (A, B, C) plus
shared PostgreSQL and Redis. Key generation (`generate-keys.ts`) and discovery
setup (`setup-discovery.ts`) scripts automate cluster bootstrap. Three example
env files document required per-instance configuration.
- **Full test suite overhaul** — Replaces the old attack/auth/discover/key/proxy
tests with a structured suite:
* `tests/federation/` — Keytools unit tests + key-rotation e2e test
* `tests/proxy/` — Proxy relay e2e tests (single-server validation)
* `tests/integration/` — Multi-instance integration tests for discover,
proxy-chain relay, and federated post delivery via BullMQ
* `tests/helpers/` — Reusable DB, identity, and auth-user utilities
* Playwright config updated to match new file conventions
* Unused helpers (`tests/helpers/queue.ts`) removed
- **Social plugin endpoints** — Rewritten `follows.ts`, `blocks.ts`, `mutes.ts`,
and `posts.ts` with proper federation integration. `social.ts` gains helpers
for looking up posts by federation URL.
### Minor changes
- **README** — Expanded from a 42-line stub to a full architecture guide with
tables for every layer (auth, DB, queues, storage, real-time), API route
documentation, setup instructions, environment variables, test coverage, and
the updated roadmap.
- **Federation helpers** — `keytools.ts` refactors imports and cleans up the public surface.
`fetch.ts`, `registry.ts`, and `proxy-helpers/federated-post.ts` pick up small
improvements. `PostFederationSchema` simplifies its encryption type assertion.
- **Plugin infrastructure** — Oven plugin schema and server index gain minor
refactors. Social client adds a `muteUser` method.
- **UI components** — `switch.tsx` and `tooltip.tsx` rewritten for Radix v2 /
Tailwind 4; `accordion.tsx`, `dropdown-menu.tsx`, `form`, `button`, `card` get
minor consistency fixes. `dialog.tsx` removes unused `DialogHeader`.
- **Server bootstrap** — `server.ts` imports DB schema before `instrumentation`
for correct Drizzle initialization, rate-limiting routes are wired, and CORS
allows federation origins. `auth.ts` regenerates Oven and social plugin schemas.
- **Dependencies** — Added `@noble/ciphers` and `@noble/hashes` (crypto
primitives). Removed `@signalapp/libsignal-client`, `base58-js`, `nanostores`,
`tweetnacl-util`, `dexie-react-hooks`, `socket.io-client`. Updated all Better
Auth packages to 1.6.11, BullMQ to 5.76.10, and various dev deps across the
board.
- **.gitignore** — Added `/audits` and `tests/docker/*.env` to prevent secret
leakage.
- **DB schema** — `blocks` table imported in `src/lib/db/schema/index.ts`.

Major changes:
- Restructure plugin architecture: moved federation logic into a dedicated `federation` plugin with Better Auth integration, defining schemas for server registry, key rotation, and blacklist management
- Extract encryption layer: new `oven` plugin handles end-to-end encryption (E2EE) with OLM client/server implementations
- Reorganize social features: consolidated social endpoints (posts, follows, blocks, mutes) and removed legacy plugin patterns in favor of unified plugin structure
- Decentralized key management: refactored `keytools` and `keygen` to support federation key rotation with challenge tokens and health checks
Infrastructure updates:
- Upgrade dependencies: bump Better Auth to 1.6.9, React to 19.2.5, Next.js to 16.2.3, Tailwind to 4.2.4
- Add cryptographic libraries: @scure/bip39, @signalapp/libsignal-client, @matrix-org/matrix-sdk-crypto-wasm for enhanced federation security
- Add utilities: base58-js, uuid for federation identifier handling
- Update database schema with new federation tables (serverRegistry, rotateChallengeTokens, blacklistedServers)
Minor updates: test suite alignment, storage client cleanup, PostFederationSchema refinements
