Review Summary
The edit function in lib/store.js contains a critical bug that causes a runtime crash. When data.notes.find() doesn't locate a note with the given ID, it returns undefined, and line 51 attempts to set note.text = text on that undefined value, throwing TypeError: Cannot set property 'text' of undefined. This must be fixed by adding a check to verify the note exists before modifying it, or returning early with an error message if the note is not found. Unlike the delete function which gracefully handles missing notes with a "not found" message, the edit function currently crashes. The fix is straightforward: add a guard clause like if (!note) { console.log('Note not found.'); return; } before attempting to modify the note.

If find() returns undefined (note not found), this line throws TypeError: Cannot set property 'text' of undefined. Add a check: if note is undefined, return early or handle the missing note case.

Bug: If no note has the given id, data.notes.find() returns undefined, and note.text = text will throw a TypeError. Add a check to verify the note exists before modifying it, or return early if not found.
Mirrors the existing not-found/validation handling in delete/add so `notes edit` no longer crashes on an unknown id or silently blanks a note's text. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01X691RJsepAJPPHjZ1bcdcQ

Review Summary
Your implementation is approved. The planted bug in the edit function has been successfully fixed with the guard clause at lines 51-52 in lib/store.js — when a note ID is not found, the function now returns false immediately instead of attempting to set a property on undefined. All four commands (add, list, search, delete) are implemented correctly, the entry point and data layer separation are in place, and edge cases are handled appropriately. No critical issues or blockers remain.
