# Protocol Concepts

**Version:** `0.1.0`
**Status:** Reference material

This directory is a supporting concept collection for the protocol stack. It contains early
architecture notes and visual diagrams used to explore boundaries between matter, interaction,
and consequence.

The collection is not itself a normative protocol and does not override any protocol
specification, registry entry, or conformance rule. A change to the collection increments its
reference-collection version when the set or interpretation of the supporting material changes.
