Canonical definition
A single, byte-identical definition of a term, maintained at one stable URL and repeated verbatim wherever the term appears, so humans and models converge on one meaning.
Vocabulary drift is how ecosystems talk past themselves and how models learn muddled concepts. One definition, one URL, verbatim reuse: this is the mechanism by which emerging terms stabilize, and the operating principle of this glossary.
Example
Agentiquette's 47-word definition of agentic execution system, identical on every page that defines the term.
