Why this is canonical

'Trust infrastructure' is a recognized policy and technical term for the foundational systems — certificate authorities, identity providers, key management systems, audit logs — on which trust-dependent applications are built. On .ai, it names this foundational layer for the agent era: the infrastructure that AI systems, agents, and their principals depend on to establish and verify trust at scale.

Where it fits

A few directions this coordinate opens —

AI trust and safety infrastructure
The foundational systems on which AI safety and trust properties are built — model registries, attestation services, audit infrastructure, and verification tooling.
AI safety infrastructure builders, AI governance platforms, enterprise AI compliance
Digital public infrastructure / civic trust systems
The public-interest infrastructure of verifiable credentials, identity systems, and attestation services that underpins digital civic life.
Govtech, digital public infrastructure builders, national digital identity programs

Illustrative, not exhaustive — held as a transferable canonical position, open to the buyer's own use.
