Preserved page disposition.

Member previewVariant 4 · 3 implementations · 60 checks per implementation

Case contract

The stipulated page lifecycle distinguishes a cached pagehide from final disposal. Timers pause on hide/freeze, dirty snapshots flush on any pagehide, and resume/pageshow may revalidate and drain retained work. Operation preserved-page-disposition 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
