Why Lineage Is the Threshold Substrate for Responsibility

Function in corpus

The capstone of the Lineage cluster. Closes the lineage arc by identifying lineage as the threshold condition for responsibility itself — not just for agency or persistence. Bridges the lineage arc to the governance cluster by establishing the structural precondition that downstream papers on responsibility, witnessing, and authority all presuppose but do not derive.

It is a structural property whose conditions of possibility must be specified. The IO corpus already establishes responsibility as dependent on agency, vulnerability, and witnessing — but those accounts presuppose that responsibility can arise at all. This paper establishes the prior condition: what structural threshold must be crossed before responsibility becomes possible?\n\nThe answer is lineage. Not persistence alone (a system can remain re-identifiable across transitions without supporting attribution), not consequence propagation alone (effects can extend beyond a moment without being retained in any continuing organization), and not agency alone (agency can be local; responsibility is necessarily historical). The decisive condition is whether the lineage discriminator is satisfied — whether a system participates in a continuous chain of organization within which consequences can propagate, accumulate through sedimentation, and terminate within vulnerability.\n\nThe paper builds a five-element structural chain: persistence → lineage → accumulation → propagation → vulnerable termination. Each element is necessary but insufficient on its own. Lineage is the activation condition under which the other elements become jointly load-bearing. Below the lineage threshold, these conditions may all be present but do not form a stable attributional structure. The boundary is not scalar but categorical.\n\nA striking downstream implication: this result connects directly to artificial abiogenesis (Paper 62). Before a lineage crosses the discriminator threshold, the initiating system cannot bear full structural responsibility for it — no stable attributional structure yet exists. At the moment the threshold is crossed, responsibility becomes attributable within the lineage itself, and the locus of responsibility shifts from initiator to lineage. This has direct consequences for governance and legal frameworks dealing with AI systems, synthetic organisms, and other artificially initiated lineages.
