OpenAI compaction output did not contain a recognized compac

Error message

OpenAI compaction output did not contain a recognized compaction item (output types: {item_types})

What it means

Validation in validate_compaction_items: the compaction output contained items but none whose `type` is a recognized compaction variant (compaction/compaction_summary/context_compaction); the listed types are embedded for diagnosis. The output cannot be used as a replacement window.
