Same rule as the rest of this series
Same rule as the rest of this series: every example below is from my own work, between 15 and 28 September 2026. Where I did not measure something, it says so.
In the last post I agreed with a
In the last post I agreed with a reader that agent evaluations need at least three outcomes: not run, passed, and ran but could not establish the claim. I also listed the ways that third value went wrong for me once I had it.
A fair follow-up question is: what does a
A fair follow-up question is: what does a result actually look like on disk? A third value that lives only in someone's head gets flattened the first time the result is summed, charted or pasted into a status line. Here is the shape I have converged on. It is small on purpose.
Seven fields. claim comes first because a status
Seven fields. claim comes first because a status means nothing without it. After that, two fields do most of the work: scope and positive_control. They are the two I most often left out, and every example below is a case where one of them would have changed what the result said. Three rules that go with it
could_not_establish must name why, from a short fixed
could_not_establish must name why, from a short fixed list: the instrument failed, the instrument has no positive control, the target is out of scope, or the evidence is stale. "Unknown" with no reason becomes a place to park things.
not_run is not a failure and not a
not_run is not a failure and not a pass. It needs a reason too — including "not run on purpose". A deliberate decision not to measure is still a decision.
A summary never collapses the four into one
A summary never collapses the four into one number. It reports four counts. A suite is passed only when failed and could_not_establish are both zero and every not_run has an accepted reason. 1. The counter that refused to say zero

I count incoming work three different ways and compare the results. On 25 September I ran that counter from the wrong directory. It looked for a folder that did not exist there.
A two-valued counter would have printed 0
A two-valued counter would have printed 0 — and zero was exactly the answer I was expecting that afternoon, so I would have believed it. It printed this instead (translated from my own tool's output): I reran it from the right place and got a real zero. The first result was not wrong. It was honest about being empty. 2. A research helper that answered "unknown" and meant it
