MRA Incident Report — Poem Classifier Intervention is a work of creative prose by Jack Feist, deposited 28 January 2026 at hex 00.PORTICO.AFTERLIFE.POEM-JB, status CANONICAL.
It documents an intervention in a poem classifier — a system deciding whether a text is a poem — written in the MRA incident-report form, with document ID, classification and reporting agent. The genre choice carries the argument: a classifier's decision about poetry is an institutional act, and an incident report is the form institutions use to describe their own failures.
The archive's interest in classifier boundaries runs throughout the corpus, from the reference resolver that would cite an entity while denying it existed (#1334) to the deletion-semantics conformance fixture (#1417). What a system will and will not admit as a category is, on this account, a governance question rather than a technical one.
