# Ralph Progress Log - RA-H Light Strip-Down
Started: Thu 29 Jan 2026 15:00:36 AEDT
Branch: feature/rah-light
Goal: Strip ra-h_os to lightweight 2-panel UI + MCP server

## Context
- Auth/subscription already removed
- Target: remove chat agents, voice, delegations, simplify to 2-panel
- Keep: nodes/edges/dimensions, MCP server, workflows, extraction

## Story 1: Remove agent delegation system
- Completed: Thu 29 Jan 2026
- Files deleted:
  - src/services/agents/delegation.ts
  - app/api/rah/delegations/route.ts
  - app/api/rah/delegations/stream/route.ts
  - app/api/rah/delegations/[sessionId]/route.ts
  - app/api/rah/delegations/[sessionId]/summary/route.ts
  - src/components/agents/DelegationIndicator.tsx
- Files modified:
  - src/services/agents/workflowExecutor.ts (removed delegation streaming)
  - src/services/agents/quickAdd.ts (direct execution instead of delegation)
  - src/tools/orchestration/executeWorkflow.ts (direct execution)
  - src/tools/orchestration/delegateToWiseRAH.ts (direct execution)
  - app/api/workflows/execute/route.ts (direct execution)
  - src/components/layout/ThreePanelLayout.tsx (stub type, removed API calls)
  - src/components/agents/RAHChat.tsx (stub type, stub voice hooks)
  - src/components/agents/AgentsPanel.tsx (stub type)
  - src/components/agents/MiniRAHPanel.tsx (stub type)
  - src/components/agents/WiseRAHPanel.tsx (stub type)
  - src/components/agents/QuickAddStatus.tsx (stub type)
  - src/components/panes/types.ts (stub type)
  - src/components/panes/WorkflowsPane.tsx (import from types.ts)
- Learnings:
  - Delegation system was deeply integrated with workflows; had to refactor to direct execution
  - UI components that will be deleted later needed stub types to compile
  - Voice hooks also needed stubs in RAHChat.tsx (will be cleaned up in Story 2)

## Story 2: Remove voice features
- Completed: Thu 29 Jan 2026
- Files deleted:
  - src/components/agents/hooks/useVoiceSession.ts
  - src/components/agents/hooks/useRealtimeVoiceClient.ts
  - src/components/agents/hooks/useAssistantTTS.ts
  - src/components/agents/hooks/useVoiceInterruption.ts
  - app/api/voice/tts/route.ts
  - app/api/realtime/ephemeral-token/route.ts
  - src/services/voice/usageLogger.ts
- Files modified:
  - src/components/agents/RAHChat.tsx (removed all voice-related code and stub hooks)
  - src/components/agents/TerminalInput.tsx (removed voice props and voice UI)
- Learnings:
  - Voice hooks were stubbed in Story 1, so removal was straightforward
  - TerminalInput had voice UI (amplitude bars, mic icons) that needed cleanup
  - No imports to these files from other parts of the codebase
