It runs test with SI on and compares result with expected.txt file; and it allows test to opt out with header (when the test is testing a non-SI-specific behavior). It knows to find SI-specific expected.txt files under mac-site-isolation / ios-site-isolation. It has a fallback comparison path for imported wpt test to eliminate false positive — SI can affect the ordering of test results, and wpt test does not care about ordering. 2218136 1 jenner 2026-06-05 14:02:29 -0700 <rdar://problem/178740802> 2218157 2 jenner 2026-06-05 14:31:57 -0700 *** This bug has been marked as a duplicate of bug 316358 ***
