Renames the app's display name everywhere (page titles, PWA manifest, TopBar, email subject lines, HMAC signature header) and its internal technical slug from chatapp to ds-chat/ds_chat: the Python package name and console script, the systemd unit and its user/group/paths, the deploy scripts, the Docker container names, and the Postgres database name. The live dev Postgres role stays "chatapp" -- renaming a role requires disconnecting the session using it, which needed a temporary superuser role Claude's auto-mode classifier correctly declined to create unsupervised. Functionally invisible (it's just a login credential), but worth knowing about if this ever needs fully cleaning up by hand. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>

# Day-2 deploy/upgrade script for the DS Chat app server. Run by hand
|
|
# over SSH as the `ds-chat` user (or via sudo -u ds-chat):
|
|
#
|
|
# sudo -u ds-chat /srv/ds-chat/deploy/upgrade.sh
|
|
#
|
|
# Fails loudly and stops before touching the running service if any step
|
|
# fails -- the previous deploy keeps running rather than being torn down
|
|
# mid-upgrade. See ../DEPLOYMENT.md for what each step assumes is already
|
|
# in place (venv, /etc/ds-chat/env, the systemd unit, Node.js).
