Client offline mutation outbox: Ack removes by identity · case 05

Ack removes by identity.

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 ack-removes-by-identity 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
