Block pair 0->1 - 1473 candidate edges
Out-degree: 63 parents, 382 children, 381 multi-parented (PolyFrac 99.7%); top-1 parent holds 25.9% of edges, Gini 0.906, max out-degree 382.
Superparents (out-degree flag): 2 (2 also pass the old fire-rate AND-gate) — e.g. feature 44 technical terminology related to programming and coding con…: 382 children, fires on 98.8% of tokens
Independence null: mean edge PMI 0.37; 1118 edges (75.9%) at chance level (PMI < 0.5). 2 edges dropped by the joint-support guard (n_joint < 30).
Frequency control: mean survival 0.998 over 1473 testable edges; 26 (1.8%) 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 0.033 over 49 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): 0.506.

Block pair 1->2 - 621 candidate edges
Out-degree: 97 parents, 402 children, 88 multi-parented (PolyFrac 21.9%); top-1 parent holds 44.0% of edges, Gini 0.932, max out-degree 273.
Superparents (out-degree flag): 0 (0 also pass the old fire-rate AND-gate)
Independence null: mean edge PMI 1.43; 260 edges (41.9%) at chance level (PMI < 0.5). 93 edges dropped by the joint-support guard (n_joint < 30).
Frequency control: mean survival 0.751 over 620 testable edges; 150 (24.2%) 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 0.178 over 52 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; 1 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): 0.223.
