Quit a game you launched from a host's library and the stream ended with
"Session ended by <host>." on the host-selection screen — an error
report for something you had just done on purpose, and several taps away
from starting the next title.
The host has always said what happened: it closes the connection with
APP_EXITED when the game it launched for a session exits, and that
code's own documentation describes this feature. Nothing ever read it —
a search across every client found zero consumers. (It also could not
reach anyone until the previous commit, since the close only happens
once the lease declares the game gone.)
The core now records the reason as it observes the close, latched before
the shutdown flag because different threads watch the two, and exposes
it as punktfunk_connection_game_exited. Purely additive: a client that
never asks behaves exactly as before, the host sends identical bytes,
and the wire version is untouched — ABI 17.
The Apple client asks while the connection is still up, then treats a
game exit as the normal finish it is: no error banner, and if the
session began as a library launch it reopens that library so the next
title is one tap away. Any other ending — a stop, the host going away,
network loss — is unchanged. The other clients keep their existing
end-of-session behaviour; the call is there when they want it.
