Deferred render transition state: Suspension preserves prior screen · case 02

Suspension preserves prior screen.

Member previewVariant 2 · 3 implementations · 60 checks per implementation

Case contract

Urgent input echoes immediately while deferred content may lag. Only the active transition can commit or clear pending work. A suspended update retains any prior screen, including empty text; first render uses fallback. Operation suspension-preserves-prior-screen has the six explicit input/output oracles below.

Why this case matters

An offline client lifecycle model that isolates a state-management defect without DOM rendering or network services.

One recorded failure
