Evaluation runs get narrowed permissions

In confined evaluation runs, allow rules from settings files are ignored; only CLI ones count.

What

With CLAUDE_CODE_EVAL_CONFINED set, file-read permission checks reject anything outside the set of paths the run was allowed to read, and always-allow rules are honoured only when they came from a command-line argument, so allow rules written in settings files are ignored.

Details
  • The denial text is source outside the readable set in an evaluation run.
  • Both paths are off entirely when the variable is unset.
