Every case

Instability

3 cases produced both outcomes

The same prompt, the same model, different results. A single run of any of these would have been a coin flip reported as a fact.
  • trigger.positive.sidebar_collapse9 passed, 1 failed
  • trigger.positive.hover_card_lift9 passed, 1 failed
  • complete.writes_toast_motion8 passed, 2 failed

Conditions

Two runs are comparable only when all of these are identical. A score that moved because the model changed is not a regression in the skill.
