# Regression test for J4-20 (BLK-006 class): toggle-external.sh:34 resolved
# REPO with a LOGICAL `cd` (no -P). Direct invocation via a symlinked path —
# exactly the real ~/.claude/lib -> <repo>/lib layout — resolves REPO to the
# SYMLINK's logical parent instead of the physical repo root, so every path
# derived from it (SKILLS_DIR, DISABLED_DIR) points at the wrong tree.
