Aug 1, 2025August 2025 monthly summary for starkware-libs/sequencer. Delivered a reliability-focused fix that decouples the JSON-RPC server initialization from the revert workflow, enabling the RPC server to run and be queryable at any time. This change ensures the RPC server future is created before the should_revert check, reducing latency and downtime during revert operations and improving debugging/monitoring capabilities. The fix aligns with the apollo_state_sync path and is documented in the commit: d94368170efbde55b393a8a4db4ef4cc7c96196c ("apollo_state_sync: RPC Server runs regardless of should_revert (#8411)").
