Unclear What values CLAUDE_CODE_PERSONAL_CONFIG_FIX accepts and what it changes are not known.

What

Claude Code reads a new environment variable, CLAUDE_CODE_PERSONAL_CONFIG_FIX. An environment variable is a named value you set in your shell before starting a program. Claude Code passes it on to the tmux sessions it starts (tmux is a tool for running terminal sessions in the background) and to other programs it launches. It is handled in the same lists as CLAUDE_CODE_RESTRICT_PERSONAL_CONFIG, which control which variables are passed on or removed.

Why

It looks like a new switch related to how personal configuration is restricted or repaired, and it now reaches every process Claude Code starts.
