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.

@shade/observer
Live observability backend for Shade — exposes a snapshot endpoint, an SSE event stream, and serves the bundled dashboard SPA.
Install
bun add @shade/observer @shade/server @shade/core
Usage
import { createObserver } from '@shade/observer';
import { ShadeEventEmitter, ShadeSessionManager } from '@shade/core';
import { PrekeyServerEvents, createPrekeyServer } from '@shade/server';
// 1. Create event emitters
const clientEvents = new ShadeEventEmitter();
const serverEvents = new PrekeyServerEvents();
// 2. Wire them into your session manager and prekey server
const manager = new ShadeSessionManager(crypto, storage, { events: clientEvents });
const prekeyServer = createPrekeyServer({ crypto, events: serverEvents });
// 3. Create the observer
const observer = createObserver({
token: process.env.SHADE_OBSERVER_TOKEN!,
clientEvents,
serverEvents,
});
// 4. Mount or serve standalone
import { Hono } from 'hono';
const app = new Hono();
app.route('/shade-observer', observer);
Bun.serve({ port: 3900, fetch: app.fetch });
After this, visit http://localhost:3900/shade-observer/dashboard/ and enter your bearer token to see the dashboard.
Endpoints
| Method | Path | Auth | Description |
|---|---|---|---|
| GET | /api/state |
Bearer | Current snapshot (identity, sessions, prekeys, server stats) |
| GET | /api/events |
Bearer (or ?token=) |
SSE stream of live events |
| GET | /dashboard/ |
None | Bundled web UI |
| GET | /health |
None | Liveness check |
Configuration
| Env var | Required | Description |
|---|---|---|
SHADE_OBSERVER_TOKEN |
Yes | Bearer token (min 16 chars). Refuses to start if shorter. |
The token is checked with constant-time comparison.
Security notes
- Event payloads contain NO key material, plaintext, or signatures — only structural facts (counters, addresses, short hashes for display).
- The observer is intended for internal/debugging use. Put it behind a reverse proxy and authenticate access.
- The dashboard stores the bearer token in
localStoragefor convenience. Don't load the dashboard on shared computers.
