Read-only in prod is the right constraint. The failure mode I'd most want to hear how you handle isn't a missing signal — it's a confident wrong diagnosis.
Running an autonomous pipeline for eight months, the three incidents that cost me the most days all had the surface error naming the wrong subsystem:
- "x264: malloc of size N failed / incorrect parameters" — I read it as a codec or bad-args bug and went looking there. It was RAM exhaustion. The encoder was the victim, not the cause.
- A 22x slowdown in an LLM step that was indistinguishable from a hang. It was swap: the model no longer fit in RAM, and the page file did the rest.
- A 27-minute "freeze" in a background job. The process was healthy; the pipe was buffering, so nothing appeared until exit.
In all three the logs were complete and the metrics were green. The mistake was in the inference drawn from them — and an agent will produce that wrong inference far faster than I did, with better prose attached to it.
So: does HyperProbe ever return "I don't know — here are two competing hypotheses and the cheapest check that separates them"? The discriminating check is the part I'd pay for. A single confident answer that's wrong is worse than no answer, because it sends a human down a road with the agent's credibility behind it.
