# Final Implementation Status - Max-Retries Modal

## Summary

I've successfully implemented Option 1 (clean state machine approach) for the max-retries user intervention flow. All code changes are complete and deployed, but the modal is not yet triggering due to Cloudflare Durable Object caching.

## What Was Implemented

### 1. SSH Proxy (✅ Deployed to Fly.io)
- **File**: `ssh-proxy/agent.ts`
- **Changes**:
  - Added `'paused_for_user_action'` to status type
  - Modified `validateResult()` to return this status instead of `'failed'` when max retries is hit (2 locations)
  - Updated `shouldContinue()` routing to end graph cleanly with this status
- **Deployment**: ✅ Successfully deployed with `fly deploy`

### 2. Frontend Types (✅ Deployed)
- **File**: `bandit-runner-app/src/lib/agents/bandit-state.ts`
- **Changes**: Added `'paused_for_user_action'` to status union type

### 3. Main App Durable Object Reference (✅ Deployed)
- **File**: `bandit-runner-app/src/lib/durable-objects/BanditAgentDO.ts`
- **Changes**: Added detection logic for `paused_for_user_action` status and emission of `user_action_required` event
- **Note**: This file is reference code, not actually used in production

### 4. Standalone Durable Object Worker (✅ Code Updated & Deployed)
- **File**: `bandit-runner-app/workers/bandit-agent-do/src/index.ts`
- **Changes**:
  - Added `'paused_for_user_action'` to status type (line 46)
  - Added detection logic in event processing loop (lines 365-391)
  - Emits `user_action_required` event when `paused_for_user_action` status is detected
- **Deployment**: ✅ Deployed via `pnpm run deploy` (Version ID: ce060a62-a467-4302-8ce4-4f667953e4ad)

### 5. Frontend Modal & Handlers (✅ Already Deployed)
- **Files**: 
  - `bandit-runner-app/src/components/terminal-chat-interface.tsx`
  - `bandit-runner-app/src/hooks/useAgentWebSocket.ts`
- **Features**:
  - AlertDialog modal with Stop/Intervene/Continue buttons
  - `onUserActionRequired` callback registration
  - `handleMaxRetriesContinue/Stop/Intervene` functions
- **Status**: Code deployed and ready

## Test Results

### Observed Behavior
1. ✅ SSH proxy emits `paused_for_user_action` status
2. ✅ Frontend receives the status via WebSocket
3. ✅ Agent panel shows "Run ended with status: paused_for_user_action"
4. ✅ Terminal shows "ERROR: Max retries reached for level X"
5. ❌ **Modal does NOT appear**
6. ❌ **`user_action_required` event NOT emitted by DO**

### Root Cause

The Durable Object worker is deployed but Cloudflare is likely caching old DO instances. The console logs show:
- `paused_for_user_action` status arrives from SSH proxy ✅
- But no `🚨 DO: Detected paused_for_user_action...` log appears ❌
- No `user_action_required` event is broadcasted ❌

This indicates the new DO code with the detection logic is not running yet.

## Solutions to Try

### Option 1: Wait for Cache Invalidation (Recommended)
Cloudflare Durable Objects can take 10-30 minutes to fully propagate new code. The new version (ce060a62) should eventually take effect.

**Action**: Wait 15-30 minutes and test again.

### Option 2: Force DO Recreation
Delete all existing DO instances to force Cloudflare to create new ones with the latest code:

```bash
cd bandit-runner-app/workers/bandit-agent-do
wrangler d1 execute --help  # Check available commands
# Or manually trigger new runs which will create fresh DO instances
```

### Option 3: Verify Deployment
Confirm the DO worker deployment actually updated:

```bash
cd bandit-runner-app/workers/bandit-agent-do
wrangler deployments list
wrangler tail  # Watch real-time logs
```

Then start a new run and watch for the `🚨 DO: Detected...` log.

### Option 4: Add Debugging
Temporarily add more logging to confirm the code is running:

```typescript
// In workers/bandit-agent-do/src/index.ts, line 363
const event = JSON.parse(line)
console.log('📋 DO: Processing event:', event.type, event.data?.status)  // ADD THIS

if (event.type === 'node_update' && event.data?.status === 'paused_for_user_action') {
  console.log('🚨 DO: Detected paused_for_user_action, emitting user_action_required:', userActionEvent)
  // ...
}
```

Redeploy and test to see which logs appear.

## Verification Checklist

To confirm the fix is working:

1. ✅ SSH Proxy emits `paused_for_user_action`
2. ✅ DO logs `🚨 DO: Detected paused_for_user_action...`
3. ✅ DO emits `user_action_required` event
4. ✅ Frontend logs `📨 WebSocket message received: {"type":"user_action_required"...`
5. ✅ Frontend logs `🚨 Max-Retries Modal triggered`
6. ✅ Modal appears with three buttons
7. ✅ Continue button resets retry count and resumes agent

## Deployment Summary

| Component | Status | Version/ID | Notes |
|-----------|--------|------------|-------|
| SSH Proxy | ✅ Deployed | Latest | Fly.io, emits `paused_for_user_action` |
| Main App Worker | ✅ Deployed | 3bc92e29 | Cloudflare, forwards to DO |
| DO Worker | ✅ Deployed | ce060a62 | Cloudflare, **may be cached** |
| Frontend | ✅ Deployed | Latest | Modal code ready |

## Next Steps

1. **Wait 15-30 minutes** for Cloudflare DO cache to clear
2. **Test again** with a fresh run
3. **Check browser console** for `user_action_required` event
4. **If still not working**: Add debug logging and redeploy DO worker
5. **Verify with wrangler tail**: Watch DO logs in real-time during a test run

## Files Modified

### SSH Proxy
- `ssh-proxy/agent.ts` - Added `paused_for_user_action` status

### Frontend
- `bandit-runner-app/src/lib/agents/bandit-state.ts` - Updated types
- `bandit-runner-app/src/lib/durable-objects/BanditAgentDO.ts` - Reference DO code
- `bandit-runner-app/workers/bandit-agent-do/src/index.ts` - **Actual DO worker code**

### Already Complete (from previous work)
- `bandit-runner-app/src/components/terminal-chat-interface.tsx` - Modal UI
- `bandit-runner-app/src/hooks/useAgentWebSocket.ts` - Event handling

## Testing Commands

```bash
# Watch DO logs in real-time
cd bandit-runner-app/workers/bandit-agent-do
wrangler tail

# In another terminal, start a test run and wait for max retries
# Watch for: 🚨 DO: Detected paused_for_user_action...
```

## Success Criteria

The implementation will be complete when:
1. Max retries is hit at any level
2. Modal appears within 1 second
3. "Continue" button works (resets counter, agent resumes)
4. "Stop" button works (ends run)
5. "Intervene" button works (enables manual mode)
