Policy Provision and Governance Inheritance from an Organisational Identity Substrate

This memo specifies how an artificial-intelligence agent runtime, bound at instantiation to a principal identity handle, resolves at session initialisation a target organisational identity substrate from a manifest source bound to the runtime's working context and retrieves from that substrate a typed policy stack comprising a handbook artefact, a standard-operating-procedure registry pointer, an enforcement-gate specification, and an audit-signal ingestion endpoint. The policy stack is then applied as runtime constraints on subsequent tool invocations, with audit signals emitted back to the same substrate. Policy provision occurs in the same act of session initialisation as principal identification, rather than as a separate ceremony against a side-channel governance plane. A principal concurrently bound to multiple organisational substrates operates the runtime under a deterministic composition of the several policy stacks, with cross-organisational residual conflicts routed to the peer-protocol Identity Accord ceremony [IDACCORD] rather than to a meta-federation authority. The memo is Informational. The wire surface relies on the DNS-based discovery of [MCPDNS] and the handle namespace of [IDPRONOUNS]; no new transport is introduced.
