From 4918236990d08c22d14a87d54edd9ff8b50aea45 Mon Sep 17 00:00:00 2001 From: Claude Date: Fri, 26 Dec 2025 23:37:14 +0000 Subject: [PATCH] feat: Migrate from TypeScript/npm to ReScript/Deno BREAKING CHANGE: Complete rewrite to follow Hyperpolymath Language Standard This commit migrates the entire codebase from TypeScript/Node.js/npm to ReScript/Deno following the Hyperpolymath Language Policy. Changes: - Convert all TypeScript source files to ReScript - Remove package.json and all npm-related files - Remove TypeScript config files (tsconfig.json, jest.config.js, etc.) - Update deno.json for ReScript-only workflow - Add Mustfile.epx for deployment state management - Add config.ncl for Nickel-based configuration - Update justfile with ReScript/Deno commands - Add language policy enforcement workflow - Update README.adoc and CLAUDE.md for new stack - Add .gitignore entries for banned files New Features: - CRDT support (G-Counter, PN-Counter, LWW-Register, LWW-Map, OR-Set) - Modern cryptography (SHA-256+, AES-256-GCM, ECDSA, ECDH) - Post-quantum crypto preparation (Kyber) Enforcement: - TypeScript files are now BANNED - npm/yarn/pnpm/bun are now BANNED - Makefile is now BANNED (use justfile) - CI workflow rejects non-compliant PRs --- .eslintrc.json | 31 -- .github/workflows/language-policy.yml | 143 +++++++ .gitignore | 12 + .prettierrc.json | 10 -
