> Note: `skill:least-to-most → skill:planning-decomposition` edge creates a soft cycle because `planning-decomposition → skill:least-to-most` does NOT exist. The edge direction is intentional: `least-to-most` recommends learning `planning-decomposition` next. No hard cycle exists.

## Graph Rules Compliance

- ✅ No nodes removed
- ✅ No edges removed
- ✅ No nodes renamed
- ✅ No graph regenerated — existing content preserved verbatim, 9 nodes appended
- ✅ Schema version held at 1.3 (no structural schema change)
