feat(edge): serve the dashboard pages from the Worker - #27
Merged

Conversation
The Caddy route, its guide and the proxy test named agent.harlanzw.com.
The Worker serves the prerendered Nuxt build as static assets after the Access check, and proxies only the API, health and WebSocket routes to the controller. CONTROLLER_URL now points at agent.wolfstar.rocks.

frame-ancestors 'none' and x-frame-options: DENY ignore frameAncestors
contentSecurityPolicy hardcodes frame-ancestors 'none' and securityHeaders sets x-frame-options: DENY, while the controller builds both from the frameAncestors option in framingHeaders. When a deployment allows framing (config frame_ancestors, e.g. a talk deck), the pages the Worker now serves can no longer be framed.
Fix: Drive the framing headers from the same setting the controller uses: add a Worker variable for the allowed framing origins and emit frame-ancestors 'self' <origins> there, omitting x-frame-options, as framingHeaders in src/app.ts does.

Problem: `frame-ancestors 'none'` and `x-frame-options: DENY` ignore `frameAncestors`. `contentSecurityPolicy` hardcodes `frame-ancestors 'none'` and `securityHeaders` sets `x-frame-options: DENY`, while the controller builds both from the `frameAncestors` option in `framingHeaders`.

serveShell serves dashboard pages with no controller password when Access is off
With ACCESS_TEAM_DOMAIN and ACCESS_AUD cleared, a documented way to turn the check off, serveShell answers any GET or HEAD from the prerendered build and proxyDashboard never runs, so the controller’s dashboard password stops guarding the pages.
Fix: Gate the shell on the controller’s password too, or refuse to serve it when dependencies.access is null, for example by only calling serveShell when Access is configured.

The dashboard hostname pointed straight at the tunnel, so it skipped the Worker and its Access check. The Worker now owns agent.wolfstar.rocks as a custom domain, and the controller moves to controller.wolfstar.rocks, which only the Worker calls.

📚 Description
The controller used to be the only place the dashboard came from, so the Worker showed nothing while the controller was down or restarting. The Worker now serves the prerendered dashboard pages itself and proxies only
/api,/health, writes and WebSockets to the controller.wolfstar-github-edgeshipsdashboard/.output/publicas Workers Static Assets withrun_worker_first, so the Access check still runs before any file is read./_nuxtand/_fontsare cached asprivate.scripts/deploy.shbuilds the dashboard beforewrangler deploy.agent.wolfstar.rocksas a custom domain, so Cloudflare Access covers the dashboard address. The controller moves tocontroller.wolfstar.rocks, which only the Worker calls.wrangler.jsonc,scripts/30-agent.caddy,scripts/public-dashboard.mdand the proxy test follow the new hostnames.agent.wolfstar.rocksto the Access application's destinations. The same audience then covers both hostnames.The interface now loads with the controller down, but its data calls fail until the controller is back. The README and
AGENTS.mddescribe the new split.
