The incumbent probe printed `HOLDERS_SOURCE=lsof` before running `lsof`, then discarded its exit status and stderr. Any `lsof` that ended with empty stdout for a reason other than "nobody holds it" therefore parsed as verdict `exited`, evidence `no-holder`, `holdersEnumerable: true` — a positive claim of absence the host never made. `classifySupersededRelay` turns that claim into `rm -f` on the socket inode, so it can unlink a path a live relay is still holding. Measured on Debian 12 against a real NFS mount whose server is blackholed: condition wall exit stdout stderr holder found no network mounts 141ms 0 pid - yes NFS healthy 143ms 0 pid - yes NFS wedged (hard) >120s KILL - - no (blocked) NFS wedged, -w >120s KILL - - no (blocked) NFS wedged, -S 2 >120s KILL - - no (blocked) any host, -b 2ms 1 - status error no (WRONG) nothing holds it fast 1 - - n/a (correct) Two things follow. `-w` and `-S` do not address the blocking, and `-b` reports no holder for a socket a live process is holding even on a host with no network mounts, so neither is a fix. And because `-t` exits 1 both for "nobody holds it" and for "could not answer", only the diagnostics separate the two. Today the block is what protects us: the probe dies before `PROBE_END`, the sentinel check fails, and the verdict is `unverifiable`. That safety is accidental, and it is spent the moment anyone bounds the probe — a `timeout` around the wedged case yields empty stdout and empty stderr, which the old script read as `exited`. So the script now decides `HOLDERS_SOURCE` after `lsof` has run: it merges stderr into stdout, treats any non-numeric word or any exit outside lsof's own 0/1 as a failure to answer, and emits `HOLDERS_SOURCE=error` — which the parser already reads as not enumerable, hence `unverifiable`. Pids lsof did report are still honoured, and an absent path stays exempt, so healthy hosts are unchanged and the reap never becomes more permissive. Per docs/reference/ssh-execution-boundary.md, a probe that could not answer is `unverifiable`, never `exited`. This does not make husks reapable on a host with a wedged mount — lsof still blocks there and the verdict stays `unverifiable`. Leaking husks is the correct failure mode; unlinking a held socket is not. A `/proc/net/unix` + `/proc/*/fd` enumeration answered that host correctly in 45ms and is the Linux-only follow-up.
