Abstract. The P-INDEP contribution (June 2026) stated the principle of independence of trust roots by foundation and left three open questions: completeness of the coupling-factor set, independence auditing without privacy loss, and the cost of physically distinct carriers. This document closes all three questions with solutions grounded in verified engineering practice and standards: (1) a transition from a closed checklist to a generative rule over the dependency graph, with precedent-driven evolution of the taxonomy through the ACP registry (PV-3); (2) a two-phase audit – a structural independence audit at the device-class level during certification, plus anonymous attestation of the instance (DAA / property-based attestation) in operation; (3) an inventory of already-existing carriers (eSE/eSIM, a network-side root based on physical-layer authentication) and a minimum-quorum scale k bound to the ACP agent classes. In addition, the document introduces the P-DELEG principle – delegation of authority to an autonomous agent launched from the device wallet without handing the agent any trust roots: authority is conveyed by a one-time evaporating mandate signed by a live quorum of roots. P-DELEG is shown to be a direct consequence of the resolution of question 2: auditing without disclosure and delegation without disclosure are realised by one and the same cryptographic mechanism. Version 0.91 extends the solutions following a diversion analysis and an inversion pass: an experimental audit phase (independence verified by compromise injection), reference quorum profiles (anonymity through uniformity), a witness root on neighbouring mesh devices, an intent model of mandate execution, and protective qualifications for the network-side root against adversarial attacks on classifiers.
