This register is one face of the Backstaff evidence system — the held instrument that holds the Astrolabe measurement engine, maps compliance controls, and engraves every evidence record into a register of record. The full reference library lives at /corpus; the alphabetical view at /corpus/glossary; the operator view at /corpus/switchboard.
