Metaharness vs Semiotic
These two are level on the tashan score (within 0 points), so the score does not decide it. The evidence rows below are where they differ. Both are measured the same way, on the same day, from public evidence only — so this is a comparison of two measurements rather than two marketing pages. How we measure ›

The full audit for each — the advisory ids, the version that fixes them and anything that runs at install time — is free on its own page: Metaharness · Semiotic.
