Verification methodology

YouTube HTTP 200 trap

youtube.com/watch?v=<fake> returns HTTP 200. Link checker cannot detect fabricated IDs. Only oEmbed 404 is valid:

curl -s -o /dev/null -w '%{http_code}' -L "https://www.youtube.com/watch?v=aB3xK9zQ1mE"   # → 200 fake
curl -s "https://www.youtube.com/oembed?url=https%3A//www.youtube.com/watch%3Fv%3DaB3xK9zQ1mE&format=json"   # → 404

A/B test titles

ID 9PxJMN7KauQ returns "What Are PDAs in Solana?" via oEmbed but renders as "There's No Database. There's No Server." in playlist. Store ID as key, fetch title at build.

Build-time version fetch

Versions from crates.io (pinocchio, litesvm, carbon-core, yellowstone-grpc-client etc), npm (@solana/kit, gill, codama), GitHub Agave stable, and solana-install.solana.workers.dev. Build fails if fetch fails — no silent fallback.

Anchor trap

Crate anchor-lang 1.1.2 and npm @coral-xyz/anchor 0.32.1 are separately versioned halves of the same project.
