CRITICAL FINDING: ListOffsets (apiKey=2) requests DISAPPEAR!
Evidence:
1. Request loop logs show apiKey=2 is detected
2. Requests reach gateway (visible in socket level)
3. BUT processRequestSync NEVER receives apiKey=2 requests
4. AND "Handling ListOffsets" case log NEVER appears
This proves requests are being FILTERED/DROPPED before
reaching processRequestSync, likely in:
- Request queuing logic
- Control/data plane routing
- Or some request validation
The requests exist at TCP level but vanish before hitting the
switch statement in processRequestSync.
Next investigation: Check request queuing between request reading
and processRequestSync invocation. The data/control plane routing
may be dropping ListOffsets requests.
