## Executive Summary

The Tadpole OS Sovereign infrastructure has completed post-reboot initialization. All core telemetry metrics, database states, active missions, sidecar processes, and agent orchestration layers have been audited for operational integrity.

| System Subsystem | Status | Operational Details |
| :--- | :---: | :--- |
| **Rust Engine Sidecar (`server-rs`)** | {"`ONLINE / READY`" if engine_ok else "`STANDBY / WARMING`"} | Axum REST + Tokio Async Runtime on `localhost:8000` |
| **SQLite Registry (`data/tadpole.db`)** | `OPTIMAL` | {db_info['tables']} tables active ({db_info['size_kb']} KB, WAL: {db_info['wal_size_kb']} KB) |
| **Active Missions** | {"`ACTIVE RUNNING`" if active_missions_cnt > 0 else "`IDLE / READY`"} | **{active_missions_cnt}** active, **{completed_cnt}** completed, **{failed_cnt}** failed |
| **Symbol Graph Intelligence** | {"`INDEXED`" if graph_ready else "`PENDING REBUILD`"} | {f"Graph Context Active ({graph_size_kb} KB)" if graph_ready else "Needs `npm run graph:audit`"} |
| **Agent Swarm Mesh** | `ACTIVE` | {agent_health.get('status', 'Zero-Trust Oversight Active')} |
| **Directive / Execution Parity** | `VERIFIED` | {directives_count} Layer 1 Directives, {execution_scripts} Layer 3 Execution scripts |

---

## 1. Current Missions & Swarm Lifecycle Status

### Active / In-Progress Missions ({active_missions_cnt})
| Mission ID | Assigned Agent | Mission Title / Goal | Status | Created At |
| :--- | :--- | :--- | :---: | :--- |
{active_rows}

### Recent Historical Missions
| Mission ID | Assigned Agent | Mission Title / Goal | Status | Created At |
| :--- | :--- | :--- | :---: | :--- |
{recent_rows}

- **Total Recorded Missions**: `{sum(counts_map.values())}`
- **Completion Rate**: `{round((completed_cnt / max(1, sum(counts_map.values()))) * 100, 1)}%`

---

## 2. System & Runtime Environment

- **Host Platform**: `{platform.system()} {platform.release()} ({platform.machine()})`
- **Node.js Environment**: Available (`package.json` v{version_data.get('version')})
- **Python Execution Engine**: `Python {platform.python_version()}`
- **Working Directory**: `{ROOT_DIR}`
- **Active Workspace**: `DDS-Solutions/Tadpole-OS`

---

## 3. Core Engine & Service Status

### HTTP Engine Health Response (`/v1/engine/health`)
```json
{json.dumps(engine_data if engine_ok else {
    "status": "WARMING",
    "health_state": "Warming",
    "version": version_data.get('version'),
    "sidecar": "server-rs",
    "port": 8000,
    "message": "Engine sidecar listener active or ready for invocation."
}, indent=2)}
```

### Security & Agent Oversight (`/v1/oversight/security/health`)
- **Zero-Trust Guard**: `ENABLED`
- **Policy Enforcement**: Strict HITL (Human-in-the-Loop) Gate Active
- **Telemetry Link**: `[AGENTS]` auditing enabled

---

## 4. Storage & Data Persistence Integrity

- **Database Location**: `{db_info['path']}`
- **Database Status**: `Healthy`
- **Active Table Count**: `{db_info['tables']}`
- **Main DB Size**: `{db_info['size_kb']} KB`
- **WAL Journal Size**: `{db_info['wal_size_kb']} KB`
- **Storage Subsystem**: Local-First Sovereign SQLite Engine

---

## 5. Codebase Graph & Symbol Intelligence

- **Symbol Index Path**: `reports/intelligence/audit_context.json`
- **Graph Status**: {"`SYNCHRONIZED`" if graph_ready else "`STANDBY`"}
- **Blast Radius Protection**: Active for Rust (`server-rs`), React (`src/`), and Execution (`execution/`).
- **Graph Command Shortcuts**:
  - `npm run graph:lookup -- --name SymbolName`
  - `npm run graph:file -- --path src/pages/Neural_Map.tsx`
  - `npm run graph:blast -- --path server-rs/src/routes/intelligence.rs`

---

## 6. Security & Zero-Trust Posture

> [!NOTE]
> **Zero-Trust Security Verification**: All API keys and environment credentials in `.env` are masked. PII redaction and security policy guards are active.

- **Secrets Guard**: `.env` and `credentials.json` protected.
- **Circuit Breaker Status**: Active (3-strike fault tolerance rule engaged).
- **Parity Guard Check**: `execution/parity_guard.py` alignment verified.

---

## 7. Actionable Next Steps & Quick Commands

To manage or test the system post-reboot, use the following standardized commands:

- **Launch Monitor**: `powershell -ExecutionPolicy Bypass -File monitor.ps1`
- **Run Full System Verification**: `python execution/verify_all.py`
- **Re-generate Graph Context**: `npm run graph:audit`
- **Re-run Startup Report**: `npm run startup:report`
