ryux-edge-cases: Edge cases

Group UX · Delivery Gate area EDGE CASES · RX-2.0. Levels are defined in ryux-core.

The happy path is not enough. Walk this list for the screen you built:

Area	Cases
Data	empty, one item, many items, long content, missing fields, duplicates
Forms	invalid, partial, failed, loading, unsaved, expired
Network	slow, timeout, offline, server failure, retry
Permissions	read-only, restricted, different roles (only roles that exist)
System	session expired, unauthorized, unexpected error

For first use and zero data, explain what will appear and give one action to start. For each case that can happen, decide what the user sees and what they can do next. Cases that cannot happen in this product do not need a design; say so in the Delivery Gate.

Does not cover: how errors are worded (see ryux-content).
