README is now pitch -> proof (real capture gif) -> quick start -> docs
pointers, with the network stack and gbhub/gbjoin/gbtype getting
explicit billing. The full technical breakdown (memory model, syscall
ABI, fork/exec/context switch, FS layout, toolchain war stories) moves
to docs/internals.md, plus previously-undocumented sections on the
network stack and the terminal/OSK.
docs: link-drop investigation resolved - drops are self-healing now2026-07-17T17:47:12Zuseruser@clank2026-07-17T17:47:12Zurn:sha1:7efcb26671563ea8f734e752e14a04455ecfd663
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.
