Anthropic's Claude Code binary for macOS ARM64 (2.1.214) shows new internal development strings, including mentions of 'internal error' conditions, 'empty_tree_fallback_enabled', and several `getInternalField` and `createInternalModuleById` calls, alongside GitHub PR linking and notification preference API endpoints.

READY TO POST:

anthropic's claude code on arm64 seems to be getting some internal dev love. spotting lots of internal error messages and module registry calls in their latest binary.

new strings in claude code suggest internal refactoring and perhaps new features with 'empty_tree_fallback_enabled'. also seeing some github pr links pop up.
