Ilker ManapandClaude Opus 5.5 aa3efcebbe Add a standby control plane with server add, and draw the screens as windows
server add gives another machine this llmgw, a certificate, the
configuration and store address, lets it into the store through Patroni, and
starts it; --vip keeps a floating address on the leader with keepalived,
following a new /leader endpoint. Nodes learn every control plane from the
leader and notice a dead one by HTTP/2 ping instead of after the kernel's
fifteen minutes. The setup, console, node and init screens are drawn full
screen in one frame: title bar, sidebar, bordered panel, key bar, dialogs.

Ilker ManapandClaude Opus 5.5 bb90a927aa Print only what must outlive init's screen, and drop bubbles
Once server init's screen closed, the whole run was printed again under the
frame that had just shown it. Now the password and the next steps are, the
whole run goes to /var/lib/llmgw/init.log (0600: it holds the password), and
it is printed in full only when init fails. Seen in a draft of the install
video, where it scrolled the screen away.

The spinner and the text field are written here instead of taken from
bubbles, whose packages query the terminal's colours as they load. bubbletea
does the same deliberately, so the query stays; the dependency goes.

Ilker ManapandClaude Opus 5.5 a1b5daceb8 Let server init ask for what it needs, and node add take several nodes
In a terminal and without --admin, server init shows a short form: the
administrator's email, the other names nodes will use (with the addresses
it found), SQLite or PostgreSQL, and the mirror, node and starter model.
Its own lines then fill in as a list — read from the writer init already
uses, so nothing in init changed — with downloads updating in place and the
password in a box until the end. The whole run, password included, is
printed again when the screen closes, so it is in the terminal's history.
The last screen says how to add a node and to back up the authority's key.

node add takes several addresses and adds them in turn, with a summary.
Suggested fabrics carry what the adapters report them to be, so a name
given for one node is used for the next on the same fabric without asking.

Tried on empty VMs: init from the form through to the starter model
serving, and two nodes added to that cluster in one command. The first
attempt at the form lost its keystrokes to the terminal colour query in a
pseudo-terminal that never answers it; a real terminal does.

Ilker ManapandClaude Opus 5.5 2a16c26575 Add a node with one command: llmgw node add, with a terminal screen
Adding a node was deploy/bootstrap/onboard-node.sh, which is not installed
anywhere and wanted the node's name, the control plane's address and a
dozen flags. It is now in the binary, run on the control plane:

    sudo llmgw node add ubuntu@10.0.0.21

The node id is the machine's hostname, and the address its agent dials is
this machine's on the route to it, checked against the server certificate.
It installs llmgw there (the release for its architecture, fetched and
checked by the node; uname rather than dpkg, so RHEL works), runs doctor
there and stops on a problem before changing anything, issues and installs
the certificate, writes agent.yaml and the unit, starts the agent, and waits
for it to join and install llama.cpp. The authority is read first, so a
missing one is said before the node is touched.

The steps are events. In a terminal they draw a checklist (bubbletea) that
asks what a script cannot: which fabric each group of active adapters is on,
grouped by the subnet manager or RoCE network they report, and whether to go
on past a problem. Elsewhere, one line per step.

Found by running it on an empty VM: ssh's "Permanently added" warning on
stderr was read as the machine's hostname, so standard error is now kept
apart; and a node added again while cordoned never counted as joined, so
joining now means a heartbeat since the restart.

llmgw node remove forgets a lost node, which otherwise stays listed until
the control plane restarts. ctl nodes no longer lists vLLM as skipped on
every CPU node. The quick install, install and onboarding docs use it.
