Listed in [Ontology · Lexicon](https://banes-lab.com/api/pages/ontology/lexicon.md), after [Core Modular Design](https://banes-lab.com/ontology/lexicon/lexicon-category-core-modular-design.md) and before [Correctness / Determinism / Verification](https://banes-lab.com/ontology/lexicon/lexicon-category-correctness-determinism-verification.md).

Every term in this category is listed as one record, with its kind, its definition and its aliases, the principles whose relations name it, the principle or contract that carries the same name where one exists, and the layer its category belongs to. A tag category also gives each term an example, which is the file the tag places or the rename from a refused word onto a covering tag.

The term's definition and every architecture edge that names the term

Freshness
A verdict stands until the definition, the term's kind or an edge that names it changes

Refusal
The resolution gate fails an edge that resolves to no term, and a definition that opens as another kind

Observation
The resolution validator's pass over every edge target and every definition opening
