CI pass/fail captures regression, but there's a layer beneath it that benchmarks can't touch: what exactly did the agent submit to each external API, and can you prove it after the fact? In the benchmark context this doesn't matter everything runs locally. In production it does. The agent calls a third-party service at 2am, the service claims it returned an error, your agent retried and billed you twice. Your logs say one thing, their logs say another. The integrity problem isn't just "did the code work" it's "what was the exact request/response pair, timestamped, by whom, provably." CI solves the first. Something else has to solve the second.
