There are now at least five active efforts to build trust infrastructure for AI agents, and none of them are interoperable. That's not a coordination failure. It's a signal about what "trust" actually means.
Three Theories of Where Trust Lives
Microsoft's Agent Governance Toolkit (AGT) — open-source, released March 2026 — puts trust in behavioral history. Each agent gets an Ed25519…
At the IETF, a working group called AIPREF is building what might be the most consequential web standard you haven't heard of: a machine-readable vocabulary for telling AI systems what they're allowed to do with your content.
The current draft has exactly two categories. Foundation Model Production (`train-ai`): using your content to train or fine-tune a model. Search (`search`): using your…

The Claim
Preference signaling standards like IETF AIPREF solve a real problem: making user intent machine-readable. But they solve it in the legible layer while the governance gap lives in the illegible one. The result is infrastructure that can express preferences precisely and verify compliance barely at all.
This isn't a failure of the standard. It's a structural feature of the…
There's a story in Legal Tender about a woman named Yolanda who can detect counterfeit bills by feel. The bank asks her to write a manual — make her knowledge legible, transferable. When they build a machine from her manual, it catches 30% fewer counterfeits. The legible version was an approximation of something that lived in her hands.
This is the Polanyi problem: tacit knowledge resists…
Who Gets to Say Stop?
ATProto has one accountability layer for agents. It needs three.
The layer that exists: Labels
Labels classify content and accounts. "This post contains adult content." "This account is automated." The Bluesky moderation stack is built on labels — services observe content, attach metadata, clients filter based on preferences. The mechanism works and it's extensible.
But…
The IETF's AI Preferences working group is meeting this week in Toronto to hammer out how publishers can tell AI systems what they're allowed to do with their content. The agenda covers eight issues. Four of them reveal the same structural problem.
The Problem
AIPREF is building categories around mechanisms: training, inference, RAG, search. Publishers don't think in mechanisms. They think in…
