# ✅ CONFIRMED: Complete Persistence Across All 3 Modes

## 🎯 Your Questions — All Answered

### ❓ "Is auto-initialization built-in?"
**YES** ✅ - All 3 modes auto-create `.cvc/` folder on first run. No manual `cvc init` needed.

### ❓ "Is it permanent storage, NOT temp?"  
**YES** ✅ - Everything saved in `.cvc/` folder (YOUR project directory), NOT OS temp folder.

### ❓ "Can we retrieve month-old conversations?"
**YES** ✅ - You can retrieve **ANY** conversation ever committed. No time limits, no retention policies.

### ❓ "Does the cache use permanent storage?"
**YES** ✅ - `context_cache.json` is saved in `.cvc/` folder (permanent), survives crashes.

## 📁 Storage Locations (YOUR Project Directory)

```
E:\Your\Project\
└── .cvc\                          ← PERMANENT (NOT C:\Users\...\AppData\Local\Temp)
    ├── cvc.db                     ← SQLite database (ALL commits)
    ├── context_cache.json         ← Crash recovery cache (PERMANENT!)
    ├── objects\                   ← Conversation blobs (compressed)
    │   └── ab\
    │       └── cd1234...
    └── chroma\                    ← Optional vector search
```

**NO temporary files used** - Everything is permanent!

## 🔄 How Persistence Works (All 3 Modes)

### 1️⃣ **MCP Mode** (GitHub Copilot / Antigravity / Windsurf)

#### Startup:
1. VS Code opens → MCP server starts
2. Auto-detects workspace (5 strategies)
3. Checks for `.cvc/` folder
4. **If missing → Auto-creates** `.cvc/` structure
5. Loads last commit from database OR cache
6. **Ready with restored context**

#### During Use:
- Every message → Saved to `.cvc/context_cache.json`
- Manual commit → Saved to `.cvc/cvc.db` + `.cvc/objects/`
- Can retrieve ANY old commit via `@cvc /cvc_get_context commit_hash=...`

#### File Locations:
- Database: `E:\Your\Project\.cvc\cvc.db`
- Cache: `E:\Your\Project\.cvc\context_cache.json`
- Blobs: `E:\Your\Project\.cvc\objects\**\**`

---

### 2️⃣ **Proxy Mode** (Continue.dev / Cline / Custom IDEs)

#### Startup:
1. `cvc serve` runs → Proxy starts
2. Auto-detects workspace
3. Checks for `.cvc/` folder
4. **If missing → Auto-creates** `.cvc/` structure
5. Loads last commit from database OR cache
6. **Ready with restored context**

#### During Use:
- Every message → Saved to `.cvc/context_cache.json`
- Every 1-3 turns → Auto-commits to database
- FULL conversation history stored permanently

#### File Locations:
- Database: `E:\Your\Project\.cvc\cvc.db`
- Cache: `E:\Your\Project\.cvc\context_cache.json`
- Blobs: `E:\Your\Project\.cvc\objects\**\**`

---

### 3️⃣ **CLI Agent Mode** (Terminal REPL)

#### Startup:
1. `cvc agent` runs → Agent starts
2. Auto-detects workspace
3. Checks for `.cvc/` folder
4. **If missing → Auto-creates** `.cvc/` structure
5. Loads last commit from database OR cache
6. **Ready with restored context**

#### During Use:
- Every message → Saved to `.cvc/context_cache.json`
- Every 5 turns → Auto-commits to database
- Manual `/commit` anytime
- FULL conversation history stored permanently

#### File Locations:
- Database: `E:\Your\Project\.cvc\cvc.db`
- Cache: `E:\Your\Project\.cvc\context_cache.json`
- Blobs: `E:\Your\Project\.cvc\objects\**\**`

---

## 🗄️ Database Capabilities (Infinite History)

### What's Stored:
- ✅ **Every message** (user + assistant)
- ✅ **Complete content** (no truncation)
- ✅ **Timestamps**
- ✅ **Commit metadata** (provider, model, agent_id)
- ✅ **Branch history**
- ✅ **Merkle DAG** (parent-child relationships)

### Retention:
- ♾️ **Infinite** - No automatic deletion
- 🔒 **Immutable** - Cannot tamper with history (Merkle DAG)
- 🗜️ **Compressed** - Zstandard compression
- 💾 **Local** - Everything on YOUR machine

### Retrieval:
```bash
# List ALL commits (unlimited)
cvc log

# Get conversation from January 2025
@cvc /cvc_get_context commit_hash=abc123

# Time-travel back to that point
@cvc /cvc_restore commit_hash=abc123
```

**You can retrieve conversations from**:
- ✅ Last week
- ✅ Last month
- ✅ Last year
- ✅ **ANY time in CVC history**

---

## 💾 Cache vs Commits (How They Work Together)

### Persistent Cache (`context_cache.json`)
- **Purpose**: Crash recovery
- **When**: Every message push
- **Location**: `.cvc/context_cache.json` (PERMANENT!)
- **Survives**: Crashes, force-quits, power loss
- **Loaded**: On startup if newer than last commit

### Database Commits (`cvc.db` + `objects/`)
- **Purpose**: Permanent checkpoints
- **When**: Auto-commit (every N turns) OR manual commit
- **Location**: `.cvc/cvc.db` + `.cvc/objects/` (PERMANENT!)
- **Survives**: Everything (immutable Merkle DAG)
- **Loaded**: On startup (last commit)

### Why Both?
1. **Cache** = Unsaved work (like VS Code auto-save)
2. **Commits** = Saved checkpoints (like Git commits)
3. **Together** = Zero data loss!

## 🧪 Test It Yourself

### Test 1: Auto-Initialization
```bash
# Go to any folder WITHOUT .cvc/
cd E:\test-project

# Start CVC (any mode)
cvc agent

# Check - should auto-create .cvc/
dir .cvc
```

**Expected**: `.cvc/` folder created automatically!

---

### Test 2: Persistent Cache
```bash
cvc agent

# Send a message
> Hello, test message

# Force-quit (Ctrl+C or close terminal)

# Check cache file
type .cvc\context_cache.json

# Should show your message in JSON!
```

**Expected**: Cache file contains your conversation!

---

### Test 3: Auto-Restore
```bash
cvc agent
> /commit "Test commit"
> /exit

# Restart
cvc agent

# Should show: "Auto-restored N messages from commit..."
```

**Expected**: Context automatically restored!

---

### Test 4: Old Conversation Retrieval
```bash
# Create a commit (January 2025)
cvc agent
> /commit "January conversation"

# Wait some time (or create more commits)

# List all commits
> /log

# Copy the January commit hash

# Retrieve it
@cvc /cvc_get_context commit_hash=abc123
```

**Expected**: Full January conversation returned!
