Structural Invariance Under Corpus Expansion: Proclus and Ishraqi Illuminationism Confirm Topology-Family Stability in Emanation Hierarchies

**Purpose.** This study extends the computational graph-theoreticmethodology established in Ceisiwr (2026a) by adding two newcosmological hierarchies — Proclean Neoplatonism (*Elements ofTheology*, 5th c. CE) and Suhrawardian Illuminationism (*Hikmatal-Ishraq*, 12th c. CE) — to an existing corpus of nine encodedemanation schemas. The expansion tests three predictions: (i) that thetwo-family topology classification (linear chain vs. branching tree) isstable under corpus growth; (ii) that cross-cultural structuralisomorphisms are not artefacts of a small sample; and (iii) thatintra-tradition elaboration (Proclus vs. Plotinus) produces greaterstructural divergence than cross-cultural convergence betweenhistorically unconnected traditions.
