# Autonomous V2 System - Fixes Applied

**Date**: November 23, 2025  
**Status**: All fixes completed including critical spam prevention ✅

---

## 🚨 CRITICAL Production Fixes (Added After Testing)

### 0a. **Channel Filtering - SPAM PREVENTION** ✅
**File**: `bot/utils/autonomous.py`

**Issue**: Bot was processing messages from ALL channels, not just the autonomous channel. This caused:
- Reactions to messages in wrong channels
- Privacy concerns (tracking all messages)
- Wasted processing

**Fix**: Added server config check to only process messages from the configured autonomous channel:
```python
# Get server config to check if this is the autonomous channel
server_config = server_manager.get_server_config(guild_id)
if not server_config:
    return  # No config for this server

# CRITICAL: Only process messages from the autonomous channel
if message.channel.id != server_config.autonomous_channel_id:
    return  # Ignore messages from other channels
```

**Impact**: 
- ✅ Only tracks messages from autonomous channel
- ✅ Won't react to messages in other channels
- ✅ Privacy protection

---

### 0b. **Startup Cooldown - SPAM PREVENTION** ✅
**File**: `bot/utils/autonomous_engine.py`

**Issue**: On bot startup, Miku immediately sent 3 messages back-to-back within 6 seconds. This happened because the engine saw message history and immediately triggered actions.

**Fix**: Added 2-minute startup cooldown:
```python
# STARTUP COOLDOWN: Don't act for first 2 minutes after bot startup
time_since_startup = time.time() - self.bot_startup_time
if time_since_startup < 120:  # 2 minutes
    return None
```

**Impact**: 
- ✅ Prevents spam on bot restart
- ✅ Gives context time to build naturally
- ✅ Much better user experience

---

### 0c. **Rate Limiting - SPAM PREVENTION** ✅
**File**: `bot/utils/autonomous.py`

**Issue**: Even with decision logic, multiple rapid messages could trigger multiple actions in quick succession.

**Fix**: Added hard rate limit of 30 seconds minimum between ANY autonomous actions:
```python
_MIN_ACTION_INTERVAL = 30  # Minimum 30 seconds between actions

# Check if we're within rate limit
if time_since_last < _MIN_ACTION_INTERVAL:
    return  # Too soon, skip
```

**Impact**: 
- ✅ Prevents rapid-fire messages
- ✅ Extra safety net beyond engine cooldowns
- ✅ Natural conversation pacing

---

## 🐛 Critical Fixes (Original)

### 1. **Presence Update Event Handler** ✅
**File**: `bot/bot.py`

**Issue**: Comment was misleading about what parameters are being passed.

**Fix**: Updated comment to accurately describe that Discord.py passes before/after Member objects with different states.

**Impact**: No functional change, but clarifies the implementation for future maintainers.

---

### 2. **Activity Tracking with Debug Logging** ✅
**File**: `bot/utils/autonomous.py`

**Issue**: No debug output to verify presence tracking was working.

**Fix**: Added detailed logging for status changes and activity starts:
```python
print(f"👤 [V2] {member.display_name} status changed: {before.status} → {after.status}")
print(f"🎮 [V2] {member.display_name} started activity: {activity_name}")
```

**Impact**: Easier to verify that presence tracking is functioning correctly.

---

### 3. **Decay Factor Calculation** ✅
**File**: `bot/utils/autonomous_engine.py`

**Issue**: Decay factor was 0.95 instead of the correct value for 1-hour half-life with 15-minute intervals.

**Before**: `decay_factor = 0.95` (gives ~81.5% after 1 hour, not 50%)

**After**: `decay_factor = 0.5 ** (1/4)` ≈ 0.841 (gives exactly 50% after 1 hour)

**Impact**: Events now decay at the correct rate as documented.

---

## ⚠️ Important Fixes

### 4. **Activity Timestamps and Expiration** ✅
**File**: `bot/utils/autonomous_engine.py`

**Issue**: Activities were stored without timestamps and never expired.

**Before**: `users_started_activity: List[str]`

**After**: `users_started_activity: List[tuple]` with `(activity_name, timestamp)` tuples

**New Method**: `_clean_old_activities()` removes activities older than 1 hour

**Impact**: 
- Activities automatically expire after 1 hour
- More accurate tracking of current user activities
- Prevents engaging users about activities they stopped hours ago

---

### 5. **Activity Deduplication** ✅
**File**: `bot/utils/autonomous_engine.py`

**Issue**: Same activity could be tracked multiple times if user stopped and restarted.

**Fix**: Before adding an activity, remove any existing entries with the same name:
```python
ctx.users_started_activity = [
    (name, ts) for name, ts in ctx.users_started_activity 
    if name != activity_name
]
```

**Impact**: Each unique activity appears only once in the tracking list.

---

### 6. **Cap messages_since_last_appearance** ✅
**File**: `bot/utils/autonomous_engine.py`

**Issue**: Counter could grow indefinitely during long sleep periods, causing inappropriate FOMO triggers.

**Fix**: Cap the counter at 100 messages:
```python
if ctx.messages_since_last_appearance > 100:
    ctx.messages_since_last_appearance = 100
```

**Impact**: Prevents Miku from immediately feeling massive FOMO after waking up from sleep mode.

---

## ✨ Nice-to-Have Improvements

### 7. **Defensive Dictionary Iteration** ✅
**File**: `bot/utils/autonomous.py`

**Issue**: Iterating over `server_manager.servers` directly could fail if dict changes during iteration.

**Fix**: Create a copy of keys before iterating:
```python
guild_ids = list(server_manager.servers.keys())
for guild_id in guild_ids:
    # Safe iteration
```

**Impact**: Prevents potential runtime errors if servers are added/removed during decay task.

---

### 8. **Periodic Decay Task Monitoring** ✅
**File**: `bot/utils/autonomous.py`

**Issue**: No way to verify the decay task was running or how many times it executed.

**Fix**: Added comprehensive logging:
```python
iteration_count += 1
uptime_hours = (time.time() - task_start_time) / 3600
print(f"🧹 [V2] Decay task completed (iteration #{iteration_count}, uptime: {uptime_hours:.1f}h)")
print(f"   └─ Processed {len(guild_ids)} servers")
```

**Impact**: Easy to verify the task is running and monitor its health.

---

### 9. **Comprehensive Debug Logging** ✅
**Files**: 
- `bot/utils/autonomous_engine.py`
- `bot/utils/autonomous.py`
- `bot/globals.py`

**Issue**: No way to understand why the engine made specific decisions.

**Fix**: Added optional debug mode with detailed logging:

**New Environment Variable**: `AUTONOMOUS_DEBUG=true` (default: false)

**Debug Output Example**:
```
🔍 [V2 Debug] Decision Check for Guild 123456
   Mood: bubbly (energy=0.90, sociability=0.95, impulsiveness=0.80)
   Momentum: 0.75
   Messages (5min/1hr): 15/42
   Messages since appearance: 8
   Time since last action: 450s
   Active activities: 2
   
   [Join Conv] momentum=0.75 > 0.63? True
   [Join Conv] messages=8 >= 5? True
   [Join Conv] cooldown=450s > 300s? True
   [Join Conv] impulsive roll? True | Result: True
   
✅ [V2 Debug] DECISION: join_conversation
```

**Impact**: 
- Easy to debug decision logic
- Understand why actions are/aren't taken
- Tune thresholds based on real behavior
- No performance impact when disabled (default)

---

## 📊 Error Handling Improvements

### Added Try-Catch Blocks
**File**: `bot/utils/autonomous.py`

**In `periodic_decay_task()`**:
- Wraps `decay_events()` call for each guild
- Wraps `save_context()` call
- Prevents one server's error from breaking the entire task

**Impact**: Decay task is more resilient to individual server errors.
