nodece opened a new pull request, #25525:
URL: https://github.com/apache/pulsar/pull/25525

   ### Motivation
   
   When `ackReceiptEnabled=false`, grouped consumer acks are sent in the 
background and local write failures were able to drop pending ack state. That 
makes best-effort ack delivery weaker than expected and increases the risk of 
ack holes that can block progress in cases like `Key_Shared` consumption.
   
   ### Modifications
   
   - retain pending grouped acks for best-effort retry when send fails and 
`ackReceiptEnabled=false`
   - keep `ackReceiptEnabled=true` on explicit future/ack-receipt failure 
semantics instead of internal pending restore
   - add coverage for both no-receipt retry behavior and ack-receipt failure 
behavior
   - expose a small `@VisibleForTesting` accessor to avoid reflection in the 
tracker test
   - update client test fixtures to mock `ctx.write(...)` consistently
