{"domain": "hypnoled", "prompt": "Review the DALI PCB schematic for safety issues: the main DALI sub-circuit uses a 1SMA4746 Zener, MB10S bridge rectifier, STN1HNK60 600V MOSFET, and EL817 optocouplers. What are the critical risks?", "expected_keywords": ["Zener", "isolation", "creepage", "high-voltage", "DALI", "safety"]}

{"domain": "hypnoled", "prompt": "Analyze the MCP_power sub-schematic: it chains L7812 -> L7805 -> LD1117S33 regulators with MCP16331 buck converter. Identify thermal and efficiency concerns for a 16V DALI bus supply.", "expected_keywords": ["thermal", "efficiency", "linear", "dropout", "dissipation", "heat"]}

{"domain": "hypnoled", "prompt": "The ESP32 sub-schematic instantiates both ESP32-WROOM (U4) and ESP32-S3-WROOM-1 N16R8 (U20) on the same board. Why is this a design issue and what should be done?", "expected_keywords": ["redundant", "duplicate", "ESP32", "cost", "consolidate", "GPIO"]}

{"domain": "hypnoled", "prompt": "Explain the role of the 1SMA4746 Zener diode (D10) in the DALI bus interface circuit. What voltage does it clamp and why is the 15V rating potentially problematic for IEC 62386 compliance?", "expected_keywords": ["1SMA4746", "clamp", "15V", "IEC 62386", "22.5V", "Zener"]}

{"domain": "hypnoled", "prompt": "Describe the galvanic isolation path in the DALI interface: how does the EL817S1 optocoupler (U15, U17) isolate the ESP32 logic side from the DALI bus high-voltage side? What is the CTR concern?", "expected_keywords": ["optocoupler", "EL817", "galvanic", "isolation", "CTR", "current transfer ratio"]}

{"domain": "hypnoled", "prompt": "Explain the DALI Manchester encoding protocol: bit timing (1200 baud, Te=416.7us), forward frame structure (start bit, 8-bit address, 8-bit data), and how the ESP32 firmware should implement TX via the BSS123 MOSFET.", "expected_keywords": ["Manchester", "1200", "416", "forward frame", "BSS123", "half-bit"]}
