Anthropic accidentally shipped a 59.8 MB source map in its npm package, exposing 512,000 lines of Claude Code's TypeScript source. The community responded with clean-room rewrites, architectural deep dives, and the fastest repo to 50K stars in GitHub history.
My guess they are not even gonna challenge the “clean room” rewrite legally: the damage is done and it’s not really gonna be mitigated if they manage to take down the rewrite.
