 # K1412 Agent
 
-K1412 Agent is a multi-user web Agent built around two deliberately different
-experiences:
-
-- **Chat** is fast, conversational, and uses Open WebUI's native tool loop.
-- **Work** is a long-running coding Agent whose loop, scheduler, context,
-  memory, tools, and sub-agents are owned by this repository.
-
-A conversation may be upgraded from Chat to Work. The upgrade is intentionally
-one-way so that two independent Agent loops never compete for the same
-conversation state.
+K1412 Agent is a multi-user web coding Agent. Every user request enters the
+same independently evolvable Agent loop; its scheduler, context policy, memory,
+tools, evidence rules, and child Agents are owned by this repository.
 
 The production instance is available at <https://agent.k1412.top>.
