# Product Experiment Evidence Closeout

## Inputs
Experiment hypothesis, preregistered metric, results export, run dates, deviations, ownership and proposed next decision.

## Workflow
1. Match result scope to the original hypothesis and metric. Keep post-hoc discoveries labelled exploratory.
2. Record interruptions, implementation differences and missing data. Do not hide an abandoned run as a clean negative.
3. Separate observed result, interpretation and next decision. Preserve uncertainty about generalization.
4. Return a closeout memo for team review without launching changes or contacting participants.

## Output contract
hypothesis | planned test | actual run | observed result | deviation | interpretation | uncertainty | next decision

## Fictional acceptance test
Fictional test reached 40 of 100 plannedusers before instrumentation failed. Record incomplete exposure and missingevents, not a proven product failure.

## Review gates
No unsupported causal claim or significance estimate. Re-test a metric changed after viewing results.
