## Thresholds (set in the brief before the data was touched)

| Check | Result | Threshold | |
|---|---|---|---|
| Named gap clusters | 62 | ≥ 8 | met |
| Occurrences in largest cluster | 1065 | ≥ 15 | met |
| Share of candidates in a named cluster | 63.9% | ≥ 40% | met |

Not in a named gap: 1,858 (36%) — long tail and micro-clusters that the same-gap rule could not unify.
