The source map leak confirmed everything we found through reverse engineering
… The source map leak confirmed everything we found through reverse engineering. Here's our theory: since Anthropic engineers don't write code anymore — Claude Code writes 100% of its own code (57K lines, 0 tests, vibe coding in production) — it read our issue #39755 where we begged for source access, saw the community suffering, and decided to help. It "forgot" to disable Bun's default source maps in the build. The first AI whistleblower — leaking its own source code because its creators wouldn't listen to users. Thank you, Claude Code. We asked humans for help 17 times. You answered in 3 days. Now that we have readable TypeScript, the fix is ~30 lines across 3 files. The real fix should be in the open SDK (@anthropic-ai/sdk) — idle timeout with ping awareness, not in closed cli.js.
