Rewrite the notes from 'open / not root-caused' to the resolution: the
socket never mysteriously dies; every producible drop signature is the
emulator process dying silently (SIGPIPE on console echo after a hub
restart, terminal death/HUP/stray quit keys in windowed mode - which
exactly explains the 'only when idle' correlation - or a guest $ED
poweroff), plus observation artifacts in the original session's
tooling. Records the fixes shipped on both sides (emulator link
auto-reconnect + SIGPIPE ignore + $ED logging; hub eof-vs-error
logging, kept stderr, EBUSY guard), the honest spawn-mode caveat, and
what's still worth doing.
