Limitations

• Draft only until live verification and actual cost reconciliation pass. The single cache-write component uses the highest published TTL rate; TTL-specific pricing is not advertised. Tools, vision, explicit reasoning, structured output and compaction are disabled pending dedicated live evidence.
