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.

@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.
