Questions¶
| Question | Topic | Status | Edited by |

Ideas to revisit¶
- Uniform area sampling gives probabilities proportional to areas.
- Update latent-coin probabilities before predicting future flips.
- Track burn time rather than physical rope length.
- Use relative ordering and clearly defined failure events in inclusion–exclusion.
