Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to The change is mergeable with owner awareness, but the compatibility tests do not verify the assigned field numbers inside the new ANN statistics message; an accidental renumbering could make future protobuf data incompatible.

Pin the SPFreshANNStats field numbers.
This test pins only the outer SPFreshSearchStats fields. It does not pin fields 1 through 15 of SPFreshANNStats.
A round trip cannot detect an inner-field renumber because the regenerated encoder and decoder will agree. Add an equivalent descriptor test for every SPFreshANNStats field.

What problem does this PR solve?
SPFresh search responses currently expose only legacy aggregate statistics.
TiDB cannot render detailed ANN execution stages in EXPLAIN ANALYZE or
distinguish an absent report from an explicitly reported all-zero result.
What is changed and how it works?
SPFreshSearchStats.annas field 16.SPFreshANNStatsfor:SPFreshSearchStatsfield numbers unchanged.proto.lock.The nested message provides presence semantics:
ann: legacy producerann: producer explicitly reported all-zero statisticsAll duration fields use unsigned microseconds.
proto.lockalso catches up the existingExplainForConnectionschemathat was already present in the protobuf source but missing from the lock.
