P-NP

P-NP is the static patch pipeline that powers Play Origin (the browser-extension mod loader, formerly "Prodigy Origin"). It's maintained by ProdigyPXP. The repo name P-NP is kept as-is — the rebrand is to the extension/loader, not this patcher.

The repository no longer runs an HTTP server. Instead, a GitHub Action fetches current Prodigy assets, applies the patcher logic, and pushes the patched files to a dedicated patched branch so they can be served from raw.githubusercontent.com.

How It Works

1. .github/workflows/patch.yml runs every 2 hours (cron) and on manual dispatch.
2. The workflow builds this project with pnpm + esbuild.
3. src/patch.ts fetches:
   • loader HTML from https://math.prodigygame.com/load
   • game.min.js from https://code.prodigygame.com
   • the matching public-game.min.js
4. The patcher writes static output files:
   • game.min.js
   • public-game.min.js
   • metadata.json (includes patchDegraded flag if patches failed)
5. The workflow commits those files to the patched branch.
6. If the workflow fails, a GitHub issue is automatically created.

Features

• 30-second fetch timeout on all network requests
• JavaScript validation before patching to catch unexpected responses
• Degraded patch detection - if core regex patterns fail, patchDegraded: true is set in metadata.json
• Error handling throughout the build and patch pipeline

Local Usage

Requirements:

• Node.js 20+
• pnpm

Install and build:

pnpm install
pnpm build

Run patch locally:

pnpm run patch

Optional custom output directory:

node dist/patch.js ./patched-output

Static File URLs

After the Action publishes to the patched branch, files are available at:

• https://raw.githubusercontent.com/ProdigyPXP/P-NP/patched/game.min.js
• https://raw.githubusercontent.com/ProdigyPXP/P-NP/patched/public-game.min.js
• https://raw.githubusercontent.com/ProdigyPXP/P-NP/patched/metadata.json
