Block pair 0->1 - 2273 candidate edges
Out-degree: 64 parents, 384 children, 384 multi-parented (PolyFrac 100.0%); top-1 parent holds 16.9% of edges, Gini 0.915, max out-degree 384.
Superparents (out-degree flag): 6 (6 also pass the old fire-rate AND-gate) — e.g. feature 32 numbers within a document: 384 children, fires on 99.5% of tokens
Independence null: mean edge PMI 0.30; 1810 edges (79.6%) at chance level (PMI < 0.5). 8 edges dropped by the joint-support guard (n_joint < 30).
Frequency control: mean survival 0.994 over 2273 testable edges; 49 (2.2%) 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 0.060 over 47 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): 0.544.
