Narrow a change that went too broad

That's too much. Keep only the changes to {{scope: e.g. the validation logic in src/forms/}} and undo the rest.

Specifically:
1. List every file you edited in the last turn
2. For each, say "keep" or "revert"
3. Revert the ones marked "revert" to their pre-change state
4. Confirm the kept changes still work in isolation (run any relevant tests)
5. Show me the final diff so I can verify the scope matches what I asked for

If a "keep" change actually depends on a "revert" change, surface that conflict instead of silently keeping both.
