Delegation Chain Governance: A Framework for Preserving Accountability Integrity Across Multi-Agent AI Architectures in Regulated Enterprises

Existing AI governance frameworks govern individual AI systems. An AI system is authorised, assessed, and registered as a discrete governance object. Its delegated authority is quantified at the system level. Its oversight obligations are assigned at the system level. Its incident management obligations are discharged at the system level. This system-level architecture is coherent for standalone systems. It is structurally insufficient for multi-agent architectures in which an orchestrating system directs one or more sub-agents, which may themselves direct further sub-agents, in a chain of delegated machine authority that no single governance register captures and no single governance control monitors. This paper identifies and formalises the delegation chain governance problem: the structural gap in enterprise AI governance that arises when a chain of delegated machine authority operates across multiple systems, each individually governed, but whose combined authority footprint, accountability lineage, and failure propagation properties are not governed as a chain. The paper makes three core arguments. First, the governance of delegated machine authority is not transitive; a system that is individually compliant with all governance obligations does not thereby make compliant the chain of authority it heads. Second, that each additional delegation layer introduces an authority gap: the downstream agent acts on instructions from the preceding layer, not directly from the original governance authorisation, and the governance basis for its actions cannot be reconstructed from the system-level register alone. Third, that chain-level governance failures are a categorically distinct failure type, not reducible to enforcement or specification failures in individual system controls. The paper introduces the Delegation Chain Governance Framework: three interlocking governance obligations that together close the chain-level gap. The Chain Authority Quantification obligation extends the system-level authority exposure model to the chain as a whole, requiring that the aggregate authority exercisable across the chain at any point in time be quantified and constrained. The Delegation Provenance obligation requires that every inter-agent instruction include a verifiable reference to the governance authorisation that confers its authority, enabling full reconstruction of the accountability lineage from the originating Board delegation to the individual sub-agent action. The Chain Integrity Assessment obligation requires periodic confirmation that all agents in the chain are individually governed and that the chain as a whole operates within its registered authority ceiling. The paper analyses five major governance frameworks and demonstrates that none imposes chain-level governance obligations.
