A launch is an event. An outcome is an observed condition.
The receipt begins with the baseline, named owner, acceptance criteria, human boundaries, and observation window. It then records what ran, what failed, where people intervened, which controls held, and what business measure changed.
Keep evidence states separate.
Projected value is an estimate. Observed performance is measured behavior. Customer validation is an approval state. Independent assurance is a distinct examination. Blending them makes the number easier to market and harder to trust.
The receipt exists to support the next decision.
Scale, revise, retrain, simplify further, change a platform component, or retire. Outcome evidence is valuable because it changes what the institution should do next—not because it makes the project look finished.
