- Daylight Blue: Cloudflare Tunnel welcome button is now purple (was orange),
keeping Claude blue / Tunnel purple / OpenCode green distinct.
- Allow enabling the Cloudflare tunnel with no CODEMAN_PASSWORD via the UI: the
toggle now pops a security confirm dialog and, on confirm, sends an explicit
per-request acknowledgeUnauthTunnel:true (new action field, never persisted).
Server logs a loud warning whenever a passwordless public tunnel starts.
curl/API/CLI stay refused unless password/env/flag — no accidental exposure.
Tests: extend test/routes/system-routes-tunnel-guard.test.ts (ack allows + not
persisted; ack:false still refuses). Verified e2e on an isolated instance
(purple button, confirm dialog, retry carries the flag, no real tunnel opened).
