Deterministic queue/worker affinity for per-flow consistency #7
Description
Problem
If a flow is handled by different workers/queues, it can break assumptions about per-flow state and distort counters.
Proposal
Ensure stable flow-to-worker mapping (hash/affinity) and document behaviour across backends. Add a debug mode to verify consistency.
Alternatives considered
Best-effort scheduling.
Additional context
Important for correctness and reproducibility.
