A corpus of 1.2 million words, 870 nodes, and twenty canonical operators no longer requires defense. It requires navigation. Didactics at this scale is not simplification; it is stratigraphic mapping. It provides entry points for readers who encounter the tail at 870 and need to understand what they are traversing. The glossary that follows is therefore not a concession to popularization. It is an infrastructural layer—a surface on which new readers can stand before drilling into the depths. The organizing dialectic is density and lightness. Density is the compaction ratio of the corpus: how much meaning is stored per node, per token, per operator. Lightness is the navigational affordance: how easily a reader or crawler can move through the field without being crushed by its mass. A healthy system requires both. Too much density without lightness produces opacity—a field that can be admired but not entered. Too much lightness without density produces evanescence—a field that can be traversed but leaves no trace. The glossary balances them.
