+#
+# When HERMES_DASHBOARD is unset (or falsy), ./run exits 0 immediately.
+# Without this finish script, s6-supervise would just restart the run
+# script in a tight loop. By exiting 125 here, we tell s6-supervise
+# "this service has permanently failed; do not restart" — equivalent
+# to `s6-svc -O`. The supervise slot reports as down, matching reality
+# (no dashboard process is running).
+#
+# When HERMES_DASHBOARD IS enabled and the run script later exits or
+# is killed, we want s6-supervise to restart it (the whole point of
+# supervised lifecycle). So we exit non-125 in that case.
+
+# Arguments passed to a finish script: $1=run-exit-code, $2=signal-num,
+# $3=service-dir-name, $4=run-pgid. See servicedir(7).
