True when the capture holds stateless events and no durableObject event at all.
Measured in drupflare/worker on 2026-08: wrangler tail --format json returned 12 stateless
events at 0-1 ms and zero durableObject events for the same invocations the Workers
Observability API reported as 15 durableObject events with a 6,509 ms max. The expensive half of
the trace was simply absent, and nothing marked it dropped. A capture in that shape is an
instrument failure, and reporting a CPU figure from it is the failure mode RULE 0 exists for.
