How we link records
| Rule | What it checks | Links |
|---|---|---|
| R4 solid | A storm report inside a warning polygon while it was in effect | 106 |
| R3 solid | An SEC 8-K that names the storm | 29 |
| R2 dashed | An airport program inside a warning that had been in effect for over 60 min (context) | 4 |
Solid lines mark rules that passed an independent check; dashed lines are context. Links are rule-based facts: each shows two records that overlap in place and time. How we know
