Member previewVariant 3 · 3 implementations · 70 checks per implementation

Case contract

The generated-file client tracks received chunk indexes, byte counts, blob readers and user gestures. Assembly uses chunk order, ready empty files remain valid, and save actions require a current gesture. Operation remaining-download-bytes 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.
