All clean. Here's a summary of what was wrong and fixed in `node.go`:

1. **Duplicate `QueryNodesWithMeta`** (lines 468-541): The old unfixed version was left in alongside the fixed version at line 391. Removed the duplicate.
2. **`CountStates`**: Had both old code (manual `stateMap` counting without SQL `COUNT(*)`) and new code (SQL `COUNT(*) ... GROUP BY`) concatenated together. The second `rows.Next()` loop was dead code since the first loop already consumed all rows. Replaced with the correct version using `SELECT column, COUNT(*) ... GROUP BY column`.
3. **`QueryNodes` line 376**: Leftover `rows.Close()` inside the scan error path (redundant with `defer`). Removed.
