Digital preservation infrastructures often prioritize the stability of content and metadata. In taxonomy, species names are formed according to the Articles listed in the International Code of Zoological Nomenclature. The reasons for these changes are rarely recorded in detail or made machine-readable. This paper examines this preservation gap. Here, we cover issues in the Code by looking at approaches to recording nomenclatural changes related to the Kākāpō Strigops habroptilus. As a potential solution, we present Codex Mutabilis, a digital journal with a publication model that documents ICZN-mandated name changes with full textual justification, persistent identifiers, and archival infrastructure. We argue that this model offers a blueprint for preserving interpretive metadata in the sciences.
