+**Permissioned intent infrastructure for apps.**

+Understand what users are trying to do.
+```
+
+Memact is infrastructure that helps apps predict user intent from approved digital activity, without giving them raw access to a user's private data.
+
+This repo is not part of the core Memact intent infrastructure. It is a separate Discord moderation and community-operations project under the same GitHub organization.
+
+## Core Memact system

+```text
+Access -> Capture -> Inference -> Schema -> Memory -> Intent
+```
+
+AutoMod should not be described as a Memact memory, capture, inference, schema, access, or intent layer.
