A real shell on the chat's own connection, opened and closed like the inspector and never beside it. The modes govern the model; what a person types is theirs, since they hold the credential and could open the same shell with an ssh client. The model cannot see the panel -- a button copies the output you choose into the composer. The session outlives the socket: closing the panel leaves a build running, and coming back reattaches with the scrollback. Two tabs share one shell and the smaller window decides the size. It ends on an idle timeout, on deleting the chat, on disabling, moving or deleting the connection, and on a restart -- which says why rather than quietly opening a fresh shell that has lost the working directory. The nginx template's `Connection ""` is right for SSE and fails every WebSocket handshake, so `location /` now uses a `map $http_upgrade`; update.sh grows a drift check for it, because the only symptom on a stale vhost is a panel that cannot connect.

# nginx vhost template for LLeMbas.

# install.sh substitutes __SITE_HOST__ and __APP_PORT__ and writes the result to
|
|
# /etc/nginx/conf.d/<host>.conf. Edit this file, not the installed copy.
|
|
#
|
|
# Assumes a self-signed certificate at /etc/nginx/ssl/<host>.{crt,key}, which
|
|
# install.sh generates. To use a real certificate, point ssl_certificate at it;
|
|
# nothing else here needs to change.

# The terminal panel is a WebSocket, and a proxy that does not pass an upgrade
|
|
# through breaks it with no error either side can report -- the browser sees a
|
|
# failed handshake, which carries no status and no reason. This map yields
|
|
# "upgrade" only when the client asked for one and the empty string otherwise,
|
|
# which is exactly what the streamed-reply case below needs, so one `location`
|

# serves both. `conf.d/*.conf` is included inside `http {}`, where `map` is
|
|
# legal; the name is prefixed because two vhosts from this template would
