The Driftproof receipt for hyperframes-cli on Claude Haiku 5.5, dated 2026-11-08, and what it can say.
hyperframes-cli on claude-haiku-5-5
Passing
A case separated upward under the band rule. That is a separation detected under the rule, not proof that the skill moved the score.
Skill token cost: +6551 input and +181 output tokens per call against no skill (measured, grading excluded).
The two arms
| arm | mean | spread across cases | cases |
|---|---|---|---|
| with the skill | 0.954 | ± 0.019 | 3 |
| without the skill | 0.494 | ± 0.086 | 3 |
Lift +0.460, ± 0.088. A spread is the sample standard deviation of the per-case means: a descriptive spread with no coverage probability. The verdict above reads each case's two bands, not these aggregates.
