CANVAS: WYSIWYG RENDERER

ContentEditable Standard 2.4

Air-Gapped Client Architecture Whitepaper

ToolAcre processes developer payloads purely in local machine volatile memory. No outbound payload packets leave the user browser session during formatting, compression, or transcoding operations.

Deterministic Sandbox Protocol

All AST modifications pass through recursive DOMPurify filters, stripping active payload injections while retaining semantic structure.

Runtime Engine Specifications

The in-browser engine benchmark verifies minimal memory footprint during intensive document parses:

Subsystem	Implementation	Max Overhead	Security Level
DOM Serializer	XMLSerializer API	< 4.2 MB	Memory Safe
XSS Sanitizer	AST Purify WebAssembly	< 1.8 MB	Air-Gap Locked
Markdown Transpiler	Zero-Dep Parser v3	< 850 KB	Isolated Thread

Quick Sample Block

// Client verification hash generator
const verifyLocalRuntime = async (buffer) => {
  const hash = await crypto.subtle.digest('SHA-256', buffer);
  return Array.from(new Uint8Array(hash)).map(b => b.toString(16).padStart(2, '0')).join('');
};

Feel free to modify this canvas directly or adjust the raw markup in the mirrored split pane.

Engine Specification

Technical Architecture & Client-Side Security Guarantees

Standard WYSIWYG editors inject telemetry, send AST passes to remote node clusters, and produce bloated vendor tags. ToolAcre enforces deterministic client execution.

DOMPurify AST Sanitization

Why client-side AST inspection strips onerror, <script>, and inline javascript: URIs before DOM injection. ToolAcre runs a strict schema white-list through an isolated virtual document fragment to guarantee zero cross-site scripting attack vectors.

Semantic HTML vs Presentational Bloat

Standard browser contenteditable generates unruly nested <span style="font-family..."> and obsolete <font> elements. ToolAcre recursively collapses typographic bloat into canonical HTML5 landmarks like <strong>, <em>, and clean semantic lists.

Air-Gapped Document Drafting

Drafting sensitive corporate engineering memos, system architecture diagrams, and internal PRDs requires strict zero-leak compliance. With ToolAcre, browser tabs can operate disconnected from WiFi networks, loading exclusively from the local Service Worker cache with zero outbound heartbeat pings.
