Fault Tolerant UX
summary
Argues that fault tolerant UX requires client-side transactional guarantees and shows a concrete implementation: Orbit.js coordinates memory, localStorage, indexedDB, REST and socket sources via promise-aware evented connectors, using JSON Patch operations that return inverses for multi-level undo and deterministic sync. Describes an Ember integration (Ember Orbit) with a canonical store, edit-forking for isolated transactions, async blocking and nonblocking connector patterns, offline queuing and replay, and an in-progress library that already demonstrates these primitives working end to end.
