Unclear What exactly counts as an 'orphaned' session head is not specified in the evidence.
What
The telemetry call that fires when a session starts now first runs through a helper that determines whether the session's starting point (its 'head') is 'orphaned', and passes that status along with the event, instead of always firing unconditionally.
Why
This lets session-start tracking distinguish sessions that resume from a disconnected or missing starting point from normal ones, which is useful for diagnosing session continuity issues.
