Fizzy Browser Session Persistence

[0guban0v]

In our local stack, users seem to get logged out of Fizzy more often than expected, while Campfire sessions stay stable. I checked the Fizzy source and found:

• magic-link lifetime is hardcoded to 15 min in app/models/magic_link.rb
• the pending-auth cookie also expires with the magic link in app/controllers/concerns/authentication/via_magic_link.rb
• the signed-in session cookie is set with cookies.signed.permanent[:session_token] in app/controllers/concerns/authentication.rb
• Session itself does not appear to have built-in expiry logic in app/models/session.rb

Questions:

1. Is there any supported config/env var for browser session lifetime or session invalidation behavior that we should be using?
2. If not, is the intended explanation that signed-in sessions should persist indefinitely unless SECRET_KEY_BASE changes, cookies are lost, or session rows are removed?
3. Is there a recommended dev-mode setup for more stable browser sessions when using the magic-link login flow locally?
