Mechanisms¶
- Pilot Expansion Ladder
- This is the efficacy-versus-effectiveness distinction made operational — something can work under ideal, closely-supported trial conditions (efficacy) yet fail in everyday practice at scale (effectiveness), and the ladder is built to find that gap while it is still cheap.
This sourceDistinguishes efficacy under ideal controlled conditions from effectiveness in everyday practice, where effects can attenuate.

Verification¶
Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.
Does it back the claim? Not recorded. The single citation of this work carries no recorded support check.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
