Metric Mismatch
Description
You have JSON server health metrics. Each record has cpu_pct (0–100), mem_pct (0–100), and a status field.
Status rules:
- "critical" if cpu_pct > 90 OR mem_pct > 90
- "warning" if cpu_pct > 70 OR mem_pct > 70 (and not critical)
- "healthy" otherwise
Your task: Find all server IDs where the stored status is incorrect.
Answer format: IDs sorted alphabetically, comma-separated.
Example: SRV-002,SRV-007
