Missing-Bar Evidence Lab
Choose a scenario, step through candidate slots, and watch the evidence ladder stop at the strongest decisive layer. The goal is to explain a diagnosis without converting missing evidence into certainty.
Evidence ladder
Current evidence for the first candidate slot.
What to notice: A materialized bar terminates immediately; no gap cause is needed.
Scenario audit trail
Rows through the current stage are evaluated; later rows remain queued. The table scrolls locally on narrow screens.
| Case | Bar | Session | Halt | Transport | Activity | Result |

Keyboard: Left Arrow = Back, Right Arrow = Step, Space = Play/Pause, R = Reset. With reduced motion, Play advances exactly one step.
