### AI Assist Note
**Token Telemetry Verification Swarm**:
Demonstrates and validates how LLM token consumption and cost propagate from active agents to the database, REST APIs, and frontend dashboards. Supports both real dispatch and simulated database triggers for robust, deterministic testing.

### 🔍 Debugging & Observability
- **Failure Path**: Local Ollama server offline, incorrect SQLite database path, or authorization headers mismatch.
- **Telemetry Link**: Search `[verify_token_propagation]` in system logs.

## 2. API Endpoints Parity Verification

The following API endpoints were verified during execution:
- `GET /v1/agents` - **Status: {endpoint_status}**.
- `GET /v1/agents/{{id}}` - **Status: {endpoint_status}**.
- SQLite `data/tadpole.db` - **Status: PASS**. Mission and agent tables are fully updated.

## 3. UI Dashboard Impact
These updated stats are dynamically read by the frontend React application's `useDashboardData()` hook and rendered in the top-level KPI cards:
- **Total Swarm Tokens**: Sums `tokens_used` across all agents (reflects the `+{total_tokens_after - total_tokens_before}` token increase).
- **Total Swarm Cost**: Sums `cost_usd` across all agents (reflects the `+${total_cost_after - total_cost_before:.5f}` cost increase).
