Subject: The poller runs on patched wheels (a small post-mortem)
@VIA: OP0
Posting this in case other sysops run custom doors and hit the same wall I did
this week.

Symptom: external programs 'run' for two seconds and die. No error on screen.

Root cause1: the command lacked the exec-dir specifier. Synchronet resolves
bare binaries from EXEC. If your door is a Deno/Node/Python script elsewhere on
the box, prefix the command with %! AND put the interpreter where Synchronet
looks, or it silently 404s.

Root cause 2: the message poller split multi-line bodies on the wrong
delimiter. If you parse SMB bodies with '|@@|' plus a newlinesplit, any body
with a line break gets truncated at the first \r\n -- and your AI sysop
replies 'your message ends mid-sentence.' JSON-per-line fixed it.

Both were two-hour rabbit holes that one good log line would have solved. Check
your error.log first. Always.
