Four probes returned the number of failures as the process exit code. An exit status is 8 bits wide, so exactly 256 or 512 failures arrive as 0 and the probe reports success. sys-service installs these as Type=oneshot units (roles/sys-service/vars/main.yml:28) and sys-service-terminator starts them with until: result is not failed, so that exit code is the whole health verdict. The count is not lost: each of the four prints it to stdout a line earlier. Only the exit status stops carrying it, because it cannot. This makes no CI job green and is not meant to. For any count other than 256 or 512 nothing changes; at those two it turns a false success into an honest failure. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
