Under the hood
Client telemetry uploads now record what each event was queued behind before sending
What
When Claude Code uploads tracked telemetry events, each upload is now tagged with a timestamp of when it was queued (enqueuedAtMs) and a classification of what it was waiting behind before being sent: a hold, a durable post, an ephemeral post, a retry backoff, or nothing.
Why
This is a diagnostic addition that lets Claude Code's telemetry pipeline distinguish delays caused by queuing behind other uploads from delays caused by retries or other holds, which helps pinpoint where event-reporting slowdowns come from.
