Maintenance Record Logger

Comprehensive Maintenance Record Logger

The Comprehensive Maintenance Record Logger is a software logging system that captures every settlement maintenance action with complete traceability of actions, personnel, timestamps, rationale, and resulting states. Stored directly within an immutable L1-DVT archive, the logger draws 1 watt of power and processes up to 10,000 structured records per year. Supporting continuous settlement operations over extended timeframes requires long-term data integrity without physical intervention, addressed by the logger's 100-year design lifetime, 500,000-hour mean time between failures, and tamper-evident hash-chained entries supporting multi-language descriptions across generational lunar missions.
