Why this is canonical

'Custody stack' applies the stack-layer framing — an organized set of infrastructure layers — to the emerging category of AI custody and provenance. The .ai TLD and substrate classification place this at the foundational layer of the agentic trust infrastructure.

Where it fits

A few directions this coordinate opens —

AI provenance infrastructure
A vertical stack — from cryptographic signing through audit logging and access control — for AI output custody.
AI trust, provenance, and governance infrastructure builders
Digital assets and tokenization
Custody infrastructure for tokenized digital assets or AI-generated intellectual property.
Digital asset custodians and IP management platform builders
