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: +8822 input and +63 output tokens per call against no skill (measured, grading excluded).
The two arms
| arm | mean | spread across cases | cases |
|---|---|---|---|
| with the skill | 0.975 | ± 0.025 | 3 |
| without the skill | 0.463 | ± 0.087 | 3 |
Lift +0.512, ± 0.091. 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.
