What

Posting an event to a cloud session now returns a named outcome instead of a value or null, so an event sent to a session that is no longer running is distinguished from a network failure.

Details
  • Outcomes: accepted (with a sequence number), session inactive, or failed with a cause separating HTTP, timeout and network errors.
  • An inactive session logs "(session not active)" and increments a remote_send_event_session_inactive counter.
  • Control responses can now supply their own message identifier and are counted as sends.
Evidence

remote_send_event_session_inactive

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
