Behind the wall

The evaluation that answers does this help? already exists and runs daily. It sits on the other side of a property line, and nothing it learns comes back.
08 · The chasm

Evaluation is split by a public/private wall

Public — published & citable · verdicts · frozen · publication cadence Private — proprietary telemetry · process · adaptive · live denominators
Left of the wall Benchmarks, studies, surveys. Optimized for generality and citation. Can only use data that can be published — so the patient is a curated vignette and the verdict is "useful or not," delivered on publication cadence.
Right of the wall Decision streams, funnels, workload-adjusted utilization, outcome reconciliation. Sits on the real data, updates daily, and improves the product — but optimizes for one deployment's next sprint and never publishes.
