Function evaluate_path_subject_safe 

pub fn evaluate_path_subject_safe(
    rules: &RuleSet,
    tool: &str,
    root: &Path,
    raw_path: &str,
    default: Decision,
) -> Decision

Like evaluate_path_safe, but for an arbitrary tool name subject instead of the read/write pseudo-tool — e.g. a rule authored against the REAL tool name with a path subject (design §4.4’s "read_file(*.env)" syntax, or an apply_patch-targeted rule). evaluate_path_safe is a thin wrapper over this for the pseudo-tool case; callers that need BOTH (the permissions gate always does — see crate::agent’s permissions_gate_denial_impl) call this function a second time with tool set to the real tool name and fold the two results together.
