Layer 1 · gemma-2-2b / 1-res-matryoshka-dc · blocks.1.hook_resid_post · 48,571 tokens over 400 docs · edge: reverse coverage ≥ 0.5, both endpoints fire ≥ 20
Block pair 0->1 - 2929 candidate edges
Out-degree: 67 parents, 383 children, 383 multi-parented (PolyFrac 100.0%); top-1 parent holds 13.1% of edges, Gini 0.907, max out-degree 383.
Superparents (out-degree flag): 9 (9 also pass the old fire-rate AND-gate) — e.g. feature 53 linguistic expressions related to organizing, planning, and…: 383 children, fires on 99.6% of tokens
Independence null: mean edge PMI 0.28; 2206 edges (75.3%) at chance level (PMI < 0.5). 28 edges dropped by the joint-support guard (n_joint < 30).
Frequency control: mean survival 1.007 over 2901 testable edges; 21 (0.7%) 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 0.046 over 47 parents; 0 over the 0.5 global threshold.
Joint-child (exact union, parents with edges): R_supp mean 0.994, R_mass mean 0.995; 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): 0.437.

Block pair 1->2 - 1861 candidate edges
Out-degree: 100 parents, 690 children, 329 multi-parented (PolyFrac 47.7%); top-1 parent holds 14.6% of edges, Gini 0.920, max out-degree 271.
Superparents (out-degree flag): 0 (0 also pass the old fire-rate AND-gate)
Independence null: mean edge PMI 2.22; 187 edges (10.0%) at chance level (PMI < 0.5). 294 edges dropped by the joint-support guard (n_joint < 30).
Frequency control: mean survival 0.529 over 1833 testable edges; 894 (48.8%) 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 0.274 over 68 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): 0.561.
