 - `CADDY_DOMAIN_SUFFIX` controls generated host as `<slug>.<suffix>` (if empty: `<user>-<slug>.local`).
 - `WEBHOOK_BASE_URL` sets absolute webhook URLs returned by API/UI (recommended behind reverse proxy).
 
-## Caddy API Behavior
+## Caddyfile Fragment Behavior
 
-On project creation, when Caddy routing is enabled, the app appends a route to:
+On provisioning/reprovision, when `CADDY_ROUTE_ENABLED=true`, the app regenerates a managed fragment containing all project routes and then runs `CADDY_RELOAD_COMMAND`.
-- `POST /config/apps/http/servers/<CADDY_SERVER_ID>/routes`
 
-Route shape:
+Each route block is:
-- `match.host = [<project host>]`
+- `<slug>.<domain> {`
-- `handle[0].handler = reverse_proxy`
+- `import auth` (name controlled by `CADDY_AUTH_IMPORT_NAME`, optional when auth enabled)
-- `handle[0].upstreams[0].dial = unix/<unix-user-home>/projects/<app>/app.sock`
+- `log`
+- `reverse_proxy unix//<unix-user-home>/projects/<app>/app.sock`
