Cross-Reference Engine

Cross-Domain Concept Cross-Reference Engine

The Cross-Domain Concept Cross-Reference Engine is a software module stored on radiation-hardened NOR flash that links related concepts across the Lunar Ark archive to enable discovery and navigation. Operating at 1 watt, the engine manages over 10,000,000 weighted links using multi-language label resolution and periodic recomputation. Surviving the unshielded radiation exposure of the lunar surface across a 100-year operational lifetime requires extreme reliability, reflected in a 500,000-hour mean time between failures. The system accommodates long-mission link evolution through machine-learning-augmented discovery and authenticated update protocols as archive records expand.
