// We need to test parseFactsResponse which is not exported.
// Instead we test via extractFacts indirectly, or we test the type + parse logic.
// Since parseFactsResponse is internal, we test the exported extractFacts behavior
// by mocking chatCompletion.

// Actually, the simplest approach: test the ExtractedFact type and ensure
// the parsing handles all action types correctly. Since parseFactsResponse
// is not exported, we replicate its logic for testing.
