| UI or UX | UI + UX - Resolved no-data content surface | UI + UX - Search recovery state | UI + UX - Recoverable failure surface |
| UI guidance | Render a resolved no-data region with a specific heading, cause text, one primary action when available, optional secondary path, and restrained illustration or icon support. | Render zero-result copy, active criteria, remove-filter actions, and alternative suggestions. | Render a persistent error region near the affected content with a specific failure heading, plain-language cause, preserved context, and recovery actions. |
| UX guidance | Help users distinguish legitimate absence from loading, no-results, error, permission, and setup conditions before offering a next step. | Help users recover when their own search or filters excluded all results. | Help users recover when expected loading, saving, validation, sync, permission, or computation fails without losing their work. |
| Good UI | No projects yet heading, short explanation, Create project primary button, Import CSV secondary button, and visible workspace context. | Zero-result state shows query/filters, result count, and clear or broaden actions. | Reports could not load appears in the report section with the saved filter, Retry, Use cached data, and Contact support actions. |
| Bad UI | A blank white table body with no text, object name, or action. | No results text alone with no criteria shown. | Tiny transient toast for a blocking failure. |
| Good UX | Users can create the first project, import existing work, or request access depending on the actual cause. | Users can remove one filter, clear all, edit query, or try suggested alternatives. | User input and filter context are preserved after failure, and retry returns to recovered content or a clear still-failed state. |
| Bad UX | The same empty message appears for loading, search no-results, permission denial, and service failure. | Telling users nothing exists when filters caused the state. | Clearing work after save failure. |
| Best fit | The product area can legitimately contain no user data. | Search, browse, or filter controls can produce an empty result set. | A system or task failure blocks expected content or action. |
| Avoid when | The absence was caused by filters or search. | There is genuinely no possible next action and the system should instead explain availability. | Nothing exists yet and the state is expected. |
| Required state | First-use empty state before any objects exist. | Zero-result state that preserves the user's criteria. | Normal expected state before failure. |
| Accessibility burden | Keep the message in normal reading order near the empty region it explains. | Announce result-count changes where search results update dynamically. | Use appropriate alert or status semantics for newly appearing critical errors. |
| Common misuse | Showing a blank page with no explanation. | Showing a blank list with no explanation. | Using a transient toast for critical errors. |
