Is my markdown content uploaded to any remote server?

No. All parsing, HTML transformation, vector layout math, and binary PDF generation occur 100% client-side in your web browser memory. Zero data is sent to external servers.

How does the two-column mode work for academic papers?

Selecting '2 Columns' applies CSS multi-column rules to the document body while automatically spanning primary section headers (H1 and H2) across both columns, adhering to standard academic publishing conventions.

What is the difference between 'Download PDF' and 'Vector Print'?

'Download PDF' uses client-side pdf-lib to instantly construct and download a .pdf binary without opening any browser dialogs. 'Vector Print' invokes the native browser print engine with calibrated @page CSS rules for pixel-perfect browser rasterization.

Can I save my work or copy it directly into Word / Google Docs?

Yes. Your draft automatically saves to your browser's local storage. Additionally, clicking 'Copy Rich Text' copies formatted HTML directly to your clipboard for instant pasting into Microsoft Word or Google Docs.

title: RFC-104: Zero-Trust Telemetry Pipeline
subtitle: Distributed Stream Ingestion & Observability Architecture
author: Toolbox Engineering Team
date: 2026-09-03
version: 1.4.0
abstract: This document specifies the architectural blueprint for our distributed telemetry pipeline, handling 50k events/sec with sub-5ms serialization latency.
keywords: [telemetry, distributed-systems, kafka, zero-trust]
---

# 1. Executive Summary

Modern high-throughput cloud environments necessitate an observable, decoupled event pipeline[^1]. This RFC presents a fault-tolerant stream architecture designed to operate across three multi-region availability zones.

## 1.1 Core Requirements

- **Zero Data Loss**: At-least-once delivery with idempotent deduplication.
- **Strict Privacy**: In-memory field redaction before disk commits.
- **Client-Side Verification**: Distributed trace verification hashes.

| Component | Target SLA | Latency (p99) | Replication Factor |
| :--- | :---: | ---: | :---: |
| Edge Ingress Gateway | 99.99% | < 2.5ms | 3 Nodes |
| In-Memory Ring Buffer | 99.999% | < 0.8ms | Memory Mapped |
| Persistent Commit Log | 99.95% | < 12.0ms | 5 Regions |

# 2. Pipeline Implementation

The serialization layer leverages zero-copy binary buffers to bypass garbage collection overheads:

```typescript
interface TelemetryEnvelope {
  traceId: string;
  timestampNano: bigint;
  payloadBytes: Uint8Array;
  checksumSha256: string;
}

export function dispatchEvent(event: TelemetryEnvelope): boolean {
  if (event.payloadBytes.length === 0) {
    throw new Error("Payload buffer cannot be empty");
  }
  return true;
}
```

# 3. Security & Governance

- [x] TLS 1.3 mutual authentication across all ingress brokers
- [x] Periodic automated key rotation via HSM
- [ ] Implement zero-knowledge audit trails for compliance

[^1]: Telemetry architectures must isolate high-velocity writes from analytical queries to maintain p99 SLA guarantees.
