Some routes not shown (bundle capped for display); the analysis above counts them all.

Ṭuruq are grouped by the source-given cluster key (SAUD/Jawāmiʿ al-Kalim), not by matn similarity — deterministic, no inference. The common link is the earliest narrator through whom the bundle first branches to several pupils; the platform shows the structure, the ʿilla judgement is the scholar's. · cluster 1664
