// @vitest-environment jsdom
// Code Mode fixture snapshot over the BUILT client graph (the workspace-flow
// idiom: real bundles via AppWebEntry, keyless FixtureApiClient transport).
// Opens the fixture history session and pins the run_code turn's rendering:
// the code-variant parent row titled by the model-authored description, its
// three always-visible nested sub-rows (bash through the sample registration,
// read through GenericToolCard, the failing read wearing the error state),
// the expanded program body, and details-panel resolution of a sub-callId.
