# ViewActionNotFound

## Overview

Error view displayed when a requested model action route does not exist.
Composes `SystemMessageCard(tone="info")` with a "404" crest showing the
unrecognized `app/model/action` key, a `TriedUrlCallout` highlighting the
action segment as the error, a `SuggestionList(shape="action")` listing the
closest model's actions by route name, sorted by string similarity to the
tried action (detail actions only when the tried route has a pk, which their
links reuse),
a `DiagnosticStrip` debug footer, and a `Back` + `Browse all actions`
actions row. HTTP verb chips in the action shape remain empty until the
server exposes per-action verb metadata.
