Tier 2 Expansion: Vedic, Apocalyptic, and Islamic Traditions in the Emanation Topology Corpus (22 Traditions)

**Purpose.** This study extends the emanation topology corpus from 17 to 22 traditions by encoding five cosmological hierarchies from Vedic, Christian apocalyptic, Islamic, and Jewish apocalyptic sources. It tests six predictions: (i) that the two-family attractor remains stable at 22 traditions; (ii) that a single tradition (the Rig Veda) can contain both topology families; (iii) that the Islamic Mi'raj produces the deepest linear chain in the corpus; (iv) that edge-weighted GED results are robust across four alternative cost matrices; (v) that direction is structurally informative for branching trees but not for linear chains; and (vi) that the compact/deep sub-clustering within linear chains remains stable under expansion.

**Design/methodology/approach.** Five traditions were encoded as labelled directed acyclic graphs (DAGs): Rig Veda Nasadiya Sukta (RV 10.129), Rig Veda Purusha Sukta (RV 10.90), Book of Revelation, Islamic Mi'raj (Sahih al-Bukhari sequence), and 1 Enoch Book of the Watchers. The full six-step computational pipeline was re-executed. Three new methodological tests were introduced: edge-weighted GED sensitivity analysis across four cost matrices (Primary, Uniform, Steep, Compressed); direction testing for all seven branching trees via edge reversal; and sub-cluster stability tracking.

**Findings.** (i) Two-family attractor confirmed at 22 traditions: 15 linear chains, 7 branching trees; the linear-chain family is tightly coherent (intra-chain GED = 3.50, separation ratio = 2.19x) while the branching-tree family is structurally diverse (intra-branch GED = 8.00), reflecting an asymmetry between the two cosmological modes (Established). (ii) Intra-tradition bifurcation demonstrated: Nasadiya Sukta classified as a linear chain (5 nodes, depth 4) while Purusha Sukta classified as a branching tree (7 nodes, branching factor 4) -- the first case of a single textual corpus spanning both families (Established). (iii) The Islamic Mi'raj is the deepest linear chain in the corpus (depth 9, z = 3.08, p = 0.005; Established). (iv) Edge-weighted GED resolved all structural isomorphisms under all four cost matrices, including a new Revelation-Bundahishn isomorphism (Established). (v) Direction matters for all 7/7 branching trees (GED > 0 under edge reversal); linear chains are structurally invariant under reversal and cross-tradition GED comparisons are unaffected -- a new symmetry asymmetry between the two families (Established). (vi) Sub-cluster silhouette = 0.60 (strong), with compact cluster expanding to 8 members and deep cluster to 7 (Established).

**Originality/value.** The intra-tradition bifurcation result is the strongest evidence yet that topology family assignment is determined by cosmological *structure*, not by tradition, culture, or geography. The direction asymmetry between linear chains and branching trees reveals a previously unrecognised structural property of the two families. The cost-matrix sensitivity analysis establishes the robustness of the edge-weighted GED methodology introduced in Ceisiwr and Aureon (2026d).
