Why

Chat messages are lost on every page reload. Operators and users need conversation continuity across sessions.

Acceptance criteria

  • loadChatHistory(agentId) and saveChatHistory(agentId, messages) helpers in ui.js; localStorage key matrix:chat:<agentId>
  • Cap at 100 messages per agent — oldest dropped first on overflow
  • Each message includes a timestamp field; displayed with existing time formatter
  • saveChatHistory called whenever a message is added (user send + assistant response)
  • On agent panel open, history is loaded and rendered before any new messages
  • "Clear History" button in Chat tab header wipes that agent's stored history and re-renders empty
  • No WebSocket or mock data layer changes; no backend changes

Out of scope

  • Multi-device sync
  • Memory or task data persistence (chat messages only)

Relevant files

  • the-matrix/js/ui.js
  • the-matrix/js/agents.js (message rendering)
  • the-matrix/index.html (Clear button)
