Client offline mutation outbox: Cancel preserves other commands · case 05

Cancel preserves other commands.

Member previewVariant 5 · 3 implementations · 60 checks per implementation

Case contract

The client outbox is an ordered UI mutation log; commands use identity, not payload truthiness. Cancellation/acknowledgment remove only matching commands, offline mode retains unsent work, and a zero send budget sends nothing. Operation cancel-preserves-other-commands 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
