 **ID:** harness-20260321
 **Statement:** Transform Mosaic Stack from a functional demo into a real multi-provider, task-routing AI harness. Persist all conversations, integrate frontier LLM providers (Anthropic, OpenAI, OpenRouter, Z.ai, Ollama), build granular task-aware agent routing, harden agent sessions, replace cron with BullMQ, and design the channel protocol for future Matrix/remote integration.

 ## Success Criteria
 
-- [ ] AC-1: Send messages in TUI → restart TUI → resume conversation → agent has full history and context
-- [ ] AC-2: Route a coding task to Claude Opus 4.6, a simple question to Haiku, a summarization to GLM-5 — all via granular routing rules
-- [ ] AC-3: Two users exist, User A's memory searches never return User B's data
-- [ ] AC-4: `/model claude-sonnet-4-6` in TUI switches the active model for subsequent messages
-- [ ] AC-5: `/agent coding-agent` in TUI switches to a different agent with different system prompt and tools
-- [ ] AC-6: BullMQ jobs execute on schedule, failures retry with backoff, admin can inspect via `/api/admin/jobs`
-- [ ] AC-7: Channel protocol document exists with Matrix integration points defined, reviewed, and approved
-- [ ] AC-8: Embeddings run on Ollama local models (no external API dependency for vector operations)
-- [ ] AC-9: All five providers (Anthropic, OpenAI, OpenRouter, Z.ai, Ollama) connect, list models, and complete chat requests
-- [ ] AC-10: Routing transparency — TUI displays which model was selected and the routing reason for each response
