UnverifiedIn online policy distillation, old response distributions shift after each policy update, and continued use introduces off-policy bias.64% similarUnverifiedPessimistic locking (SELECT ... FOR UPDATE) eliminates lost updates and race conditions by serializing access to contended rows, but it reduces throughput, increases latency, may exhaust the connection pool and introduces deadlock risk.63% similarUnverifiedIn the "wrong policy" case, the root cause is that an outdated index or missing metadata filtering caused the retrieval layer to return high-confidence chunks of an old refund FAQ, rather than LLM hallucination.61% similarUnverifiedWhen PRs that swallow exceptions are merged in bulk, system observability gradually degrades: the drop in the monitoring dashboard's error rate is not because the problems are fixed, but because errors are no longer reported, and downstream may receive illegal nil values and trigger failures that are hard to trace.61% similar
