What

The task event queue caps at 1000 entries. When full it now throws away new streaming deltas outright rather than evicting an older event to make room, so task start, notification and status events survive a burst of streaming output. It also drops streaming deltas when the primary sink is off and nothing is listening.

Details
  • Eviction telemetry keys bookend_evicted and nonbookend_evicted are unchanged.
  • Unconditional in the queue; no flag.
Evidence

nonbookend_evicted

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