# Mission Scratchpad — MS19 Chat & Terminal System

> Append-only log. NEVER delete entries. NEVER overwrite sections.
> This is the orchestrator's working memory across sessions.

## Original Mission Prompt

```
Plan MS19+, update mission artifacts for Coolify → Portainer transition.
MS18 is complete. Coolify deprecated, Portainer migration in progress with another agent.
```

## Planning Decisions

### 2026-02-25 — Infrastructure Assessment

**Existing chat infrastructure (~95% complete):**

- ChatOverlay.tsx, ConversationSidebar.tsx, ChatInput.tsx, MessageList.tsx
- useChat hook with conversation management and LLM interaction
- Backend LLM controller with SSE streaming support
- Providers: Ollama, Claude, OpenAI
- Chat persistence via Ideas API

**Existing terminal infrastructure (UI-only):**

- TerminalPanel.tsx with tabs, rich output styling, animations
- No backend connection — purely mock UI

**Existing orchestrator infrastructure:**

- Orchestrator service (NestJS, port 3002) with agent spawn/kill/status
- SSE stream at /agents/events for real-time agent status
- Web proxy routes at /api/orchestrator/\*
- Coordinator integration in API for job tracking

**Key pattern reference:**

- Speech gateway (`apps/api/src/speech/speech.gateway.ts`) shows namespace WebSocket pattern with session management

### 2026-02-25 — Architecture Decisions

**Decision: node-pty for terminal backend**

- Standard PTY management for Node.js (used by VS Code)
- Spawns real shell processes (bash/zsh)
- Handles resize, input/output streams
- WebSocket namespace /terminal for communication

**Decision: Terminal sessions in PostgreSQL**

- Consistent with workspace isolation pattern
- Prisma model: TerminalSession (id, workspaceId, name, status, createdAt, closedAt)
- Sessions survive page reload, recover on reconnect

**Decision: SSE for chat streaming (not WebSocket)**

- Backend already has SSE setup in LLM controller
- Only frontend wiring missing (streamChatMessage() is TODO)
- SSE is simpler and sufficient for unidirectional token streaming

**Decision: Orchestrator commands as chat prefixes**

- /spawn, /status, /jobs, /kill parsed in frontend
- Route through existing /api/orchestrator/\* proxy
- Display structured responses inline in chat

### 2026-02-25 — Portainer Migration

**Context:** Coolify has been deprecated and shut down. Infrastructure migration to Portainer is being handled by another agent. All deployment references updated from Coolify to Portainer in PRD and mission manifest.

**Impact on MS19:**

- Deployment target is now Portainer (was Coolify)
- No code changes needed — only infrastructure config
- Smoke testing blocked until Portainer stack is running

## Session Log

### S1 — 2026-02-25
