etcd sends ONE broadcast WatchResponse with watch_id=-1, deferred until every watcher on the stream is synced (watchable_store.go:510-539). We send one empty response PER WATCHER carrying its real watch id, emitted immediately from the recv-loop fiber while event fibers are still delivering asynchronously (app/etcd/grpc.lua:522-533 vs grpc.lua:336-427). Impact: clients keying on watch_id=-1 to recognise a progress broadcast do not see it; the 'all watchers caught up' guarantee is not provided. Race-shaped: argued from code structure, not from an observed failure — needs a reproducer first.
RequestProgress emits a single watch_id=-1 response gated on all stream watchers being caught up; reproducer test exists.
No outgoing dependencies.
Nothing depends on this issue.
