PX3 — governance for shared knowledge

A three-tier authority standard for knowledge corpora maintained by humans and AI agents together.

When humans and AI agents maintain a body of knowledge together, the default state is that everything is equally writable. That default fails quietly: foundational decisions get edited like formatting choices, contradictions accumulate, and no reader — human or machine — can tell what is settled from what is provisional.

PX3 answers this with an authority gradient. Every document in a governed corpus declares its tier — its governance weight:

The mechanism that makes this agent-native rather than policy-on-paper: the governance travels with the content. Tier and status ride in each document’s metadata, so any agent reading the corpus knows, per document, what it may touch, what needs review, and what it must never rewrite.

This site is itself a small PX3-governed corpus — every page you’re reading declares its tier, and the raw tree is served for agents at /raw/.

The standard’s surfaces

The memory layer is the standard’s sibling — governance says what may change; memory says what happened.
