rauchg.com: rebuilding an RSC blog from captured Flight output

Requirements & limits

• Prerequisites: The documented rauchg.com snapshot used Next 16.1.1, Turbopack and React 19 canary. The tooling requires Node.js 22+ and a local Chrome/Chromium for comparison; some stages invoke version-pinned external tools. Repeating the method needs an authorized target snapshot and a separately built reconstruction, not just the skill repository.
• Scope: Flight decoding exposes delivered element trees, route state and client-module references. The reconstructed server-component source is explicitly an inference from that output; flight-to-mdx also needs site-specific shape/link adaptations.
• Testing evidence: The author reports 18/18 routes passing a Flight semantic gate and a runtime sweep for this case. The gate compares normalized trees and enforces a global module-ID bijection. It normalizes build-hash namespaces and selected encoding differences; configured prop/class exclusions can omit registered fields or subtrees.
• Testing evidence: The gate does not check CSS, so layout, fonts and rendered pixels need separate comparisons. Public synthetic self-tests include changed-text rejection and rejection of a one-to-many module mapping.
• Limits: The method explicitly leaves unobserved error responses, database/write paths, server caches, dynamic-image generator source and unlinked routes unresolved. The author also notes possible model-training familiarity with a nominally blind target.
• License: MIT applies to the skill and tooling, not to reconstructed websites, their scripts, fonts or other assets. The source documents separate authorization/publication decisions and private, noindex output defaults.
