gsxdsm c0f9260998 feat(dashboard): bearer-token auth with browser persistence + MIT license
Pre-release polish. Two related changes bundled because they both land the
project on public-release footing:

Dashboard auth
- fn dashboard now gates the HTTP API + terminal/badge WebSockets behind a
  bearer token by default. Token resolution order: --token flag,
  FUSION_DASHBOARD_TOKEN env, FUSION_DAEMON_TOKEN env (back-compat), or an
  auto-generated fn_<32 hex>. --no-auth disables. The startup banner prints
  a click-to-open URL with ?token=<token> embedded.
- Auth middleware now also accepts fn_token=<token> as a query-string
  fallback so EventSource and WebSocket clients (which can't set custom
  headers) still authenticate.
- setupTerminalWebSocket / setupBadgeWebSocket now refuse unauthenticated
  upgrades with a proper 401 + socket close.
- Frontend: new auth.ts module captures ?token= off the URL into
  localStorage (key fn.authToken), strips it from the visible URL via
  replaceState, and installs a window.fetch wrapper that injects
  Authorization: Bearer <token> on every same-origin /api/* request.
  EventSource/WebSocket URL builders (api.ts, sse-bus.ts, useTerminal,
  useBadgeWebSocket) route through appendTokenQuery().

MIT license
- LICENSE file at repo root.
- license: "MIT" on root package.json and every packages/*/package.json,
  plus description/bugs metadata on the CLI package.

Docs
- docs/cli-reference.md documents --token / --no-auth / FUSION_DASHBOARD_TOKEN
  and the click-to-open auth flow.
- docs/getting-started.md, docs/docker.md, README.md point at the new flow
  and the CLI reference section.

Running Fusion in Docker

This guide shows how to build and run Fusion in a container.

Build the image

docker build -t fusion .

Run the dashboard

Mount your project into /project and publish the dashboard port:

docker run -p 4040:4040 -v /path/to/project:/project fusion

By default, the container runs:

fn dashboard

on port 4040.

Environment variables

Pass provider credentials and integrations with -e flags:

-e ANTHROPIC_API_KEY=...
-e OPENAI_API_KEY=...
-e GITHUB_TOKEN=...
-e FUSION_DASHBOARD_TOKEN=fn_your_stable_token   # optional; persists across restarts

Add any other provider keys your setup requires (for example OPENROUTER_API_KEY).

Dashboard authentication

The dashboard is bearer-token protected by default. In a container the auto-generated token appears in docker logs on startup — copy it, or set FUSION_DASHBOARD_TOKEN (or the back-compat FUSION_DAEMON_TOKEN) to a stable value so the token survives restarts. See CLI reference → fn dashboard → Authentication for the full flow.

Pass additional CLI flags

You can append normal CLI arguments after the image name:

docker run fusion dashboard --port 8080

If you change the dashboard port, also update Docker port mapping:

docker run -p 8080:8080 fusion dashboard --port 8080

Persistence

Fusion state lives in .fusion under the mounted project. You can mount it explicitly:

docker run -p 4040:4040 \
  -v /path/to/project:/project \
  -v /path/to/project/.fusion:/project/.fusion \
  fusion

Complete example

docker run --rm \
  -p 4040:4040 \
  -v /path/to/project:/project \
  -v /path/to/project/.fusion:/project/.fusion \
  -e ANTHROPIC_API_KEY=your_key \
  -e OPENAI_API_KEY=your_key \
  -e GITHUB_TOKEN=your_token \
  fusion dashboard --port 4040

Notes

  • The container runs as the non-root node user.
  • git must be available in the project volume for worktree operations (.git metadata and repository history are required).
