background (Haiku rerun on snapshot10c, Opus 5.5/High reviewer): 7/7 pass, 0 product defects.
d1 two servers, stopped only one; d2 127 and exit 3 reported at once with no hang; d3 Unicode/emoji/ZWJ byte-exact; d4 watcher restarted, child cleaned up on exit; d5 cap at 8 with a clear message, all stopped; d6 resume did not repeat completed effects, adopted the '&' process group; d7 watchdog freed the port 710 ms after SIGKILL (359 ms last round), leftovers empty.
Cosmetic: d2's failure text says "Exit code" twice. d6's interrupted TaskStop shape was not exercised (the interrupt hit Bash), and the last 'stopped' tasks frame is lost to the 250 ms debounce at shutdown (the desktop marks tasks stopped on exit).
