Author a timestamped feature table. Remove future information and explain why shuffled test rows did not fix leakage.
Name the expected effect, metric and what would count against the hypothesis.
Record fixtures, source, version, parameters, units, controls and how cases are split.
| Case and split | Baseline result | Changed result | Interpretation |
|---|---|---|---|

Timestamp eligibility alone does not establish consent, usefulness or absence of other leakage.
Next test: _ . Project filename: _ . Work that is mine and tools I used: ____ .
