Suppose a pilot comes back positive: the treated group beats the control group on the headline measure, the delta lands on a single slide, and the room starts talking about rollout.

Operations has a number in front of it, and the number has not moved. A flat line can mean the thing measured is genuinely flat, or that the instrument stopped reading. Only one of those is a fact about contractors. The other is a fact about a reader that received a value it had not been taught, declined to parse it, and turned its entire lane into "missing" while the chart kept its axes. In LangGraph terms that reader is a node in a StateGraph, which is where the fix belongs.

The read-out was flat. The room split into the two explanations always available after a null: the model wasn't good enough, or the test was too small. Both assume the experiment was about the model. Both usually miss the point. The forecast, written down before the run, said every candidate was predicted to move the metric by less than the design could resolve.

Three weeks after the read-out, the meeting happens. Not the launch review — the other one. Someone from procurement, or legal, or the VP who inherited the budget, asks how the cohort was chosen. The room looks for a document that predates the number and finds a deck that postdates it. The evaluation criteria live on a single slide, written in the week the traces started looking good. The success threshold appears in the same sentence that reports clearing it.
