What
Claude Code sometimes repairs structured data whose special characters were escaped twice. That repair now removes keys that could be used to tamper with the program's own internal objects, and records how many it removed. Separately, one internal source of model requests, repl_sampling, is no longer in a list of request sources.
Why
This hardens how Claude Code repairs malformed data.
