Document the ACPI thermal zone pattern used across multiple mainboards that implement five-level fan control via power resource state machines. This pattern is used by 9 mainboards including Google Chromebooks (beltino, jecht variants), Samsung stumpy, and Intel reference boards (wtm2, baskingridge, emeraldlake2). The documentation covers: - Power resource state machine implementation - Temperature management via PECI/SuperIO - Active and passive cooling policies - Critical FNP4._OFF no-op requirement for Windows compatibility - Implementation variations and checklist for new boards Initial framework generated by Cursor AI, heavily edited thereafter.
