plugin.install refuses grant from a request unless the session was started to allow it, so the test from main that installs with grant turns that on. The install dialog's comment names OK's Sense::click.

//! `plugin.clearCache` without an id empties the cache of every installed plug-in and leaves their
|
||
//! settings.
|
||
//!
|
||
//! A test binary of its own: installed plug-ins are process-wide, so clearing every plug-in's cache
|
||
//! in the engine's other tests would empty the caches those tests check.
|
||
// Integration tests: unwrapping and panicking on failure is fine here, unlike in shipped code (AGENTS.md › Robustness).
