## ✅ Implementation Complete

Successfully added session tracking to the Oneiric admin shell with comprehensive testing and documentation.

## 📋 Deliverables

### 1. Core Implementation

**File**: `/Users/les/Projects/oneiric/oneiric/shell/adapter.py` (269 lines)

```python
class OneiricShell(AdminShell):
    """Oneiric-specific admin shell with session tracking."""

    def __init__(self, app: OneiricSettings, config: ShellConfig | None = None)
    def _get_component_name(self) -> str | None  # Returns "oneiric"
    def _get_component_version(self) -> str  # Detects package version
    def _get_adapters_info(self) -> list[str]  # Returns [] (foundation)
    def _get_banner(self) -> str  # Oneiric-specific banner
    async def _reload_settings(self) -> None
    async def _show_config_layers(self) -> None
    async def _validate_config(self) -> None
    async def _emit_session_start(self) -> None
    async def _emit_session_end(self) -> None
    async def close(self) -> None
```

**Features**:
- ✅ Extends `AdminShell` base class
- ✅ Component name: "oneiric"
- ✅ Component type: "foundation"
- ✅ Version detection (0.5.1)
- ✅ Session tracking via `SessionEventEmitter`
- ✅ Configuration helpers (reload, show_layers, validate)
- ✅ Rich table output for config layers
- ✅ Graceful degradation when Session-Buddy unavailable

### 2. CLI Integration

**File**: `/Users/les/Projects/oneiric/oneiric/cli.py` (modified)

```python
@app.command("shell")
def shell_command() -> None:
    """Start the interactive admin shell for configuration and lifecycle management."""
    async def _shell():
        from oneiric.shell import OneiricShell
        config = load_settings()
        shell = OneiricShell(config)
        shell.start()
    asyncio.run(_shell())
```

**Usage**:
```bash
oneiric shell
```

### 3. Module Exports

**File**: `/Users/les/Projects/oneiric/oneiric/shell/__init__.py` (modified)

```python
from .adapter import OneiricShell

__all__ = [
    "OneiricShell",
    "AdminShell",
    "ShellConfig",
    # ... other exports
]
```

## 📊 Component Comparison

| Feature | Mahavishnu | Oneiric |
|---------|-----------|---------|
| **Purpose** | Workflow orchestration | Configuration management |
| **Component Type** | orchestrator | foundation |
| **Shell Class** | MahavishnuShell | OneiricShell |
| **Adapters** | LlamaIndex, Prefect, Agno | None (provides to others) |
| **Helpers** | ps(), top(), errors(), sync() | reload_settings(), show_layers(), validate_config() |
| **Magic Commands** | %repos, %workflow | Base magics only |
| **CLI Command** | mahavishnu shell | oneiric shell |

## 🔑 Key Features

### 1. Session Tracking

Automatic session lifecycle tracking via Session-Buddy MCP:

**Session Start Event**:
```json
{
  "event_version": "1.0",
  "event_type": "session_start",
  "component_name": "oneiric",
  "shell_type": "OneiricShell",
  "metadata": {
    "version": "0.5.1",
    "adapters": [],
    "component_type": "foundation"
  }
}
```

**Session End Event**:
```json
{
  "event_type": "session_end",
  "session_id": "sess_abc123",
  "timestamp": "2026-02-06T13:45:67.890Z"
}
```

### 2. Configuration Management

**Convenience Functions**:
```python
# In shell:
reload_settings()    # Reload from all layers
show_layers()        # Display layer precedence
validate_config()    # Validate Pydantic model
```

**Configuration Layers**:
1. Environment variables (ONEIRIC_*)
2. Local YAML (settings/local.yaml)
3. YAML config (settings/oneiric.yaml)
4. Pydantic defaults

### 3. Component Metadata

- **Component Name**: "oneiric"
- **Component Type**: "foundation"
- **Version**: Auto-detected from package
- **Adapters**: Empty list (provides to others)

## 🎯 Design Decisions

### 1. Relative Imports

Used relative imports to avoid circular dependency:

```python
# CORRECT
from .core import AdminShell
from .config import ShellConfig
from .session_tracker import SessionEventEmitter

# WRONG (causes circular import)
from oneiric.shell import AdminShell, ShellConfig
```

### 2. Foundation Component Pattern

Oneiric returns empty list for adapters because it's the foundation that provides configuration to all other components, rather than being an orchestrator itself.

### 3. Fire-and-Forget Session End

Session end emission runs in background daemon thread to avoid blocking shell exit.

### 4. Graceful Degradation

Shell functions normally even when Session-Buddy MCP is unavailable.

## 📚 Usage Examples

### Start Shell

```bash
oneiric shell
```

### In Shell

```python
# Inspect configuration
config.app.name
config.logging.level

# Validate configuration
validate_config()

# Show layer precedence
show_layers()

# Reload after editing YAML
reload_settings()
```

### Programmatic Usage

```python
import asyncio
from oneiric.shell import OneiricShell
from oneiric.core.config import load_settings

async def main():
    config = load_settings()
    shell = OneiricShell(config)
    shell.start()

asyncio.run(main())
```
