- itemImport: check response.ok in fetchAppDetails so a genuine 404 (from the appload return-type fix) is reported as 'Failed to find app id' instead of being parsed as a successful import; applied to the source and the committed compiled bundle. - phpunit.xml: point the schema URL at 12.5 to match the installed PHPUnit 12.5.x. - ColorHelpersTest: exercise the get_brightness() non-hex stripping the test name promised (interior separators), which the prior assertion never covered.
