Extension handler detail
What the Screen Is For
Inspect a handler, edit or change its standing, and exercise it with example input.
What It Shows and Lets People Do
Overview shows handler kind, implementation, capture setting and sample health. Non-built-in handlers expose an editor; enablement and disablement use the sample adapter. The test tab validates JSON and uses declared examples. A safeguard-resume control also calls the sample adapter and has no corresponding reset route in the examined service. There is no delete control in the detail component.
States and Errors
Outside mock mode the enclosing layout displays an unavailable message. Loading and errors pass through the preview query-state component. Successful local behavior is not evidence of a connected service or of production permission enforcement.
Patterns It Must Respect
Configuration layout permits these pages only in mock mode. QueryState uses LoadingLine, Alert and retry controls for preview reads. Tabs, DefinitionList, handler editor Sheet and a JSON test form. Preview controls contain no extension permission guard; production APIs authorize independently.
