/// A GitHub delivery forwarded to this session, reduced to the event name.
///
/// Quinjet treats a delivery purely as a signal that something changed and then
/// re-reads the pull request through `gh`. Nothing from the request body is
/// trusted or displayed, which is what makes an unauthenticated loopback
/// listener safe: the worst a forged request can do is trigger a refresh that
/// would have happened on the next poll anyway.
