+ * on a machine is NOT under Codeman's control — a discovery walk with no ceiling
+ * is an unbounded loop over data someone else produces, so sockets and panes are
+ * both hard-capped. Second, an ssh handshake is an order of magnitude slower than
+ * a local `exec`; reusing the shared 5s `EXEC_TIMEOUT_MS` would classify every
+ * remote host as unreachable, so the probe gets its own timeout.
