Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to Rebasing a parent with multiple child layers can drop sibling relationships and produce an incomplete layer graph. This is a bounded but concrete correctness risk that should be fixed or explicitly accepted before merging. Suggested reviewers: 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

96-107: 🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy liftPreserve all parent-to-child relationships during rebasing.
When multiple layers share
old_parent_path, the first iteration moves the complete child vector. The next iteration extracts an empty node and then mutateskey(). The current test covers only one rebased child.Update the parent map once per parent, or move only the affected relationship. Add a regression test with two sibling layers under a rebased parent.
