+# Story 266: Matrix bot structured conversation history
+
+## User Story
+
+As a user chatting with the Matrix bot, I want it to remember and own its prior responses naturally, so that conversations feel like talking to one continuous entity rather than a new instance each message.
+
+## Acceptance Criteria
+
+- [ ] Conversation history is passed as structured API messages (user/assistant turns) rather than a flattened text prefix
+- [ ] Claude recognises its prior responses as its own, maintaining consistent personality across a conversation
+- [ ] Per-room history survives server restarts (persisted to disk or database)
+- [ ] Rolling window trimming still applies to keep context bounded
+- [ ] Multi-user rooms still attribute messages to the correct sender
+
+## Out of Scope
+
+- TBD
