Why this is canonical

'Stack' evokes the full layered architecture, not a single component — the .ai TLD positions this as the canonical name for agentic and AI-native attestation infrastructure built as a cohesive system. It is the organizing name for builders who want to own the full attestation surface rather than a single layer.

Where it fits

A few directions this coordinate opens —

AI trust infrastructure
The complete attestation stack for AI systems — from hardware root-of-trust at the base to AI governance and audit at the surface.
AI platform builders, trust infrastructure, hardware security module teams
Enterprise identity / compliance stack
A unified attestation stack for enterprise environments — integrating identity, compliance, and audit into a cohesive attested system.
Enterprise IAM platforms, GRC vendors, compliance automation

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