The Apache (cac) image healthcheck was curl -f http://localhost/, which also fails on 4xx. A new standalone site with an empty docroot gets 403, so it shows unhealthy forever, and WHP's monitor restarts it as "PHP wedged" 3 times an hour (seen on the fresh-install test VM).

Now: unhealthy only on no answer (000) or a 5xx.

Tested the new command inside a running cac:php85 container on the test VM: empty docroot (403) returns 0; no listener (000) returns 1.

WHP PR #111 also stops the monitor restarting on a 4xx healthcheck, so the fleet is covered before these images roll out. Takes effect per site on its next recreate.

The Apache (cac) image healthcheck was `curl -f http://localhost/`, which also fails on 4xx. A new standalone site with an empty docroot gets 403, so it shows **unhealthy** forever, and WHP's monitor restarts it as "PHP wedged" 3 times an hour (seen on the fresh-install test VM). Now: unhealthy only on no answer (000) or a 5xx. Tested the new command inside a running cac:php85 container on the test VM: empty docroot (403) returns 0; no listener (000) returns 1.
