Reaching it meant an SSH tunnel, because the page lived on the admin listener
and that listener is bound to loopback. Opening the port was never the way to
fix that: it also serves pprof, and pprof can dump the process heap, where
every API key sits in plaintext. Exposing the port would have been exposing
the key store.
So the page moves rather than the port. The same dashboard is now mounted at
/admin on the client-facing port, behind the session and CSRF machinery that
already guards /profile, gated on a flag on the account. The admin listener
keeps pprof and metrics and stays on loopback.
One bit, not a role system: it grants looking. Everything that changes the
cluster or issues a credential stays on the CLI, where it needs a shell rather
than a session — which keeps the worst case of a stolen admin cookie to "saw
the cluster" rather than "drained your fleet".
Someone without the flag gets 404, not 403. A 403 confirms the page is there
and that admin accounts exist here, which is free reconnaissance; 404 is what
every other unknown path returns. The profile page does not show a link to a
door the visitor cannot open.
