PR timeline for identical cold summary + unrelated scoped invalidation:
 25.4 unrelated invalidation sent
 45.5 unrelated invalidation completed
661.5 source summary completed
=> unrelated invalidation took 20.1 ms and completed while source read remained pending.
These are individual real-server observations, not benchmark medians.

Nearby behavior: cold pullRequests.stack(source), followed by same-scope invalidation:
 25.7 same-scope invalidation sent
328.8 stack read completed
329.4 same-scope invalidation completed
=> same-scope invalidation still waited for the read.
Subsequent pullRequests.summary(source, allowStale:false) succeeded with fresh observedAt.
