# `screens.*` diagnostics

Owner: the pages spec (`defs/pages.ts`). The status is the code's own; the exit comes from its category (`CATEGORIES`). A warning or info code never sets the status or the exit.

|---|---|---|---|---|---|---|---|
| <a id="screens.persona_unknown"></a>`screens.persona_unknown` | reference | error | 400 | 2 | no | — | `persona`, `known` |
