- Redirect all status messages in caddy.sh to stderr (add_route, remove_route, reload_caddy) - Redirect status message in authorized_keys.sh to stderr (rebuild_authorized_keys) - Fix install.sh to source authorized_keys.sh library and call rebuild_authorized_keys directly

# lib/caddy.sh — Caddy admin API wrapper
|
|
#
|
|
# Interacts with Caddy admin API on 127.0.0.1:2019 to:
|
|
# - Add site blocks for <project>.disinto.ai → reverse_proxy 127.0.0.1:<port>
|
|
# - Remove site blocks when deregistering
|
|
#
|
|
# Functions:
|
|
# add_route <project> <port> → adds Caddy site block
|
|
# remove_route <project> → removes Caddy site block
|
|
# reload_caddy → sends POST /reload to apply changes
