# Architecture Review Package

This sample combines the elements Telescopo preserves in a PDF export: headings, tables, syntax-highlighted code, Mermaid diagrams, KaTeX mathematics, images, and document styling.

## Executive Summary

The system receives a request, validates it, processes work asynchronously, and records the result. Landscape orientation is useful when the sequence diagram or table needs additional horizontal space.

## Architecture

```mermaid
sequenceDiagram
    participant Client
    participant API
    participant Queue
    participant Worker
    participant Store
    Client->>API: POST /jobs
    API->>Queue: Enqueue validated job
    Queue-->>Worker: Deliver work item
    Worker->>Store: Persist result
    Store-->>Client: Result available
```

## Capacity Model

\[
\text{throughput} = \frac{\text{completed jobs}}{\text{elapsed seconds}}
\]

## Delivery Table

| Stage | Owner | Output | Verification |
| --- | --- | --- | --- |
| Validate | API | Accepted request | Schema passes |
| Process | Worker | Computed result | Tests pass |
| Persist | Store | Durable record | Read-back succeeds |

## Example Code

```typescript
export async function submitJob(payload: JobRequest): Promise<JobResult> {
  const validated = schema.parse(payload);
  return queue.submit(validated);
}
```
