Unusual cited paths, rarest first. Historical facts; shared leads do not establish rivalry.
1 published paths of 1 eligible.
Ascending motif frequency, intermediate distinct-neighbor degree, maximum actor path frequency, stable ID. Counts use all eligible deduplicated paths before the limit; no size or amount inputs.
Shared leads use the latest eligible round per actor/company (round URL breaks same-date ties); director paths use a bounded interval or the latest filing observation per person/company. Only citations for the selected fact/date are retained. Ambiguous intervals are omitted.
No normalized cited primary competition facts; shared industry or lead does not prove rivalry.
