Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🟡 Moderate · up to This PR keeps a native Everything connection alive and changes failure handling, but invalid reconnects may leak resources, native failures may appear as empty results, cancellation may leave callers blocked, and valid non-fast-sorted results may be rejected. These can cause missed results, UI stalls, or resource leaks, so merge should wait for fixes or explicit owner acceptance.

In `@Plugins/Flow.Launcher.Plugin.Explorer/Search/Everything/EverythingApiV3.cs`:
- Line 366: Update the availability check around Everything3_GetMajorVersion so
a nonzero replacement client handle is destroyed via Everything3_DestroyClient
when the version check fails, before returning false; preserve successful
clients in _client and avoid destroying a null handle.
- Line 136: Update the call to
Everything3ApiDllImport.Everything3_IncRunCountFromFilenameW to capture and
validate its native result before handling IPC errors; when it returns 0, invoke
CheckAndThrowExceptionOnErrorFromEverything3() so disconnected clients are
handled and failures are not silently ignored.

- The third and fourth arguments are reversed. This overload expects
(engineName, resolution, message, errorIconPath), so users currently see the icon path as the error title and the localized SDK error text is treated as an image path. Pass the SDK message before the image path, as the other branches above do.

Everything3_Searchis a synchronous native call, and the token is not observed while it runs. The SDK providesEverything3_ShutdownClientto cancel active requests from another thread.

- This is a synchronous wait from WPF-bound property getters (
FastSortWarningVisibilityandSortOptionWarningMessage), while searches hold the semaphore for their full enumeration. Opening or refreshing settings during a search can therefore freeze the UI for up to one second per binding. Use a non-blocking acquisition here (or move the check to an asynchronous cached path).

Error-code capture can be corrupted, and semaphore timeouts can produce incorrect fast-sort warnings.

Plugins/Flow.Launcher.Plugin.Explorer/Search/Everything/EverythingApiV3.cs:53
- Read the SDK error before logging.
Everything3_GetLastErroris a wrapper around the calling thread's Win32GetLastError, soLogDebug(or anything it invokes) can overwrite the failure code first. That can turn a disconnected/invalid call into the wrong exception or no exception at all. Capture the code immediately after the failed native call, then log and map that captured value.
Plugins/Flow.Launcher.Plugin.Explorer/Search/Everything/EverythingApiV3.cs:158 - A semaphore timeout does not mean the sort option is slow, but returning
falsereports exactly that to both settings properties. If a search owns the semaphore for over a second, even a fast-sort property shows the non-fast-sort warning, potentially until another property notification occurs. Preserve the last known result or perform this metadata check through a non-contending client instead of usingfalseas the timeout state.
