LogViewer reports follow state; JSON expansion can be controlled; pure transformation helpers emit nothing.
Callback props run after the documented input is accepted. Callbacks are not cancellable unless their return type or description states otherwise.
Interaction and capabilities
Viewers scroll and filter; JSON nodes expand or collapse; diff output remains deterministic in static mode.
The published manifest records keyboard, focus, pointer, theme, terminal, semantic, event, and dependency requirements.
