Block pair 0->1 - 2428 candidate edges
Out-degree: 58 parents, 382 children, 382 multi-parented (PolyFrac 100.0%); top-1 parent holds 15.7% of edges, Gini 0.919, max out-degree 382.
Superparents (out-degree flag): 5 (5 also pass the old fire-rate AND-gate) — e.g. feature 15 technical documentation-like language, including code snipp…: 382 children, fires on 98.9% of tokens
Independence null: mean edge PMI 0.22; 2087 edges (86.0%) at chance level (PMI < 0.5). 14 edges dropped by the joint-support guard (n_joint < 30).
Frequency control: mean survival 1.031 over 2428 testable edges; 25 (1.0%) are frequency-driven (survival < 0.5).
Sibling redundancy (global Jaccard — confounded proxy, not the splitting verdict; the parent-conditioned version is in the stage-03 second pass): mean 0.054 over 42 parents; 0 over the 0.5 global threshold.
Joint-child (exact union, parents with edges): R_supp mean 1.000, R_mass mean 1.000; 0 parents with one child holding >=90% of their energy (rename candidates).
Joint-child coverage (min(1, ΣF) upper bound — saturates when children co-fire, kept only for contrast with the exact union): 0.559.

Block pair 1->2 - 280 candidate edges
Out-degree: 98 parents, 193 children, 36 multi-parented (PolyFrac 18.7%); top-1 parent holds 27.9% of edges, Gini 0.895, max out-degree 78.
Superparents (out-degree flag): 0 (0 also pass the old fire-rate AND-gate)
Independence null: mean edge PMI 1.89; 75 edges (26.8%) at chance level (PMI < 0.5). 48 edges dropped by the joint-support guard (n_joint < 30).
Frequency control: mean survival 0.764 over 277 testable edges; 77 (27.8%) are frequency-driven (survival < 0.5).
Sibling redundancy (global Jaccard — confounded proxy, not the splitting verdict; the parent-conditioned version is in the stage-03 second pass): mean 0.032 over 28 parents; 0 over the 0.5 global threshold.
