Responsibility Infrastructure.
The operational layer that records the complete lifecycle of responsibility from identification through receipt.
Responsibility Infrastructure is the institutional category for provable operational responsibility. It exists because responsibility cannot be trusted if it cannot be reconstructed.
The category is constituted by four institutional surfaces: Standards (RI-STD), Registry (RI-REG), Rail (RI-RAIL), and Governance (RI-GOV). Each surface is independently specified.
A Responsibility Infrastructure record captures seven operational events: identification, assignment, acceptance, action, evidence, verification, and receipt. The record is the unit of reconstruction.
The category applies wherever responsibility crosses institutional, organisational, or system boundaries — including AI-assisted operations where conventional accountability mechanisms are insufficient.
