Unclear The finding doesn't say what triggers this or what pct represents, so it's unclear which part of Claude Code gains its own log level.

What

A new internal call, s.extend({ level: pct }), creates a child logger with a specific logging level set explicitly, rather than inheriting a default one.

Why

This is an internal logging change and doesn't directly affect what you see while using Claude Code, but it lets a specific part of the code log at its own chosen verbosity level.
