Large-Scale Campus Access Architecture

Great Grand Master Keying (GGMK) coordinates multi-building campuses spanning thousands of doors across 4 access tiers:

[GGMK: Campus President] ──> All Buildings
   └── [GMK: Building Dean] ──> Entire Science Building
          └── [MK: Department Head] ──> Chemistry Wing Labs
                 └── [CK: Individual Professor] ──> Office #304

Multiplex Partitioning

To prevent excessive wafer stacking, GGMK systems partition buildings using multiplex paracentric keyway families.
