arXiv 2607.22448 targets on-prem and air-gapped pipelines running quantized 4-8B models behind tool servers, where the dominant failure is omission: an agent reads 20 of 400 records and reports "no anomalies." A 75,476-trial sweep across five models and two engines found a pooled omission rate of 0.62, and 68% originates in deterministic middleware (ingestion, chunking, retrieval plumbing), not model behavior. If you're debugging omissions by swapping models, you're working the wrong 32%. (arXiv 2607.22448)
