+        92 — which is why it went unread. Each addition below was checked
+        against what the solver actually does with `and_or`:
+
+        - `assembly` (61,652 edges): AND is correct — a Complex IS the AND of
+          its subunits. It is also inert under the default config, because
+          `DS_ASSEMBLY_LIMITING` routes assembly inputs to a limiting-reactant
+          (min) rule before the AND/OR branch is reached
+          (reaction_model.jl, `activator_is_assembly`).
+        - `depletion` (5,064 edges): inert. `create_reaction_from_edges` pushes
+          depletion edges to their own vector and never records `is_and`.
+        - `dissociation` (82,394 edges): live, and inconsistent with every
+          other producer edge — all 116k `output` edges are `or`, these are
+          `and`. They feed terminal readout sinks with exactly one producer
+          each, so the question is only whether a lone parent gets the
+          `hill_log` tanh (AND) or passes through (OR). Measured: hill_log is
+          identity to four decimals at both classification cutoffs (0.85 and
+          1.15) and within 0.1% out to fold 2, only compressing large folds
+          (100 -> 74). Flipping them to `or` and re-benchmarking moved nothing
+          real — all 11 changed predictions were in one pathway and none had
+          both arms converged. Inconsistent but immaterial; left as-is rather
+          than changed without evidence.
