Record bounded production neighborhood observation

[jithinmathws]

Summary

Record the bounded production observation after deploying the neighborhood query batching change.

For the same depth=2&limit=25 request, the pre-update response took 18.82 seconds. Two post-update responses took 4.67 and 4.09 seconds. All three returned HTTP 200 with the same 9,412-byte body and SHA-256.

Scope and limits

• Documentation only; no application, database, or deployment changes.
• The deployment advanced 56 commits, so the timing difference cannot be attributed solely to batching.
• Two post-update samples do not establish typical latency or concurrent capacity.
• An immediate health check returned a transient 502 after restart; the retry returned 200 and the service remained active.

Validation

git diff main...HEAD --check passed.
