Satis

This is not a separate goddess

Satis is the Greek form of Satet (sṯt). The census carries both; its own snippet for this slug begins "Satet, Satit or Satjet, Satjit in Ancient Egyptian… Greek: Satis" — the same article, reached under a redirect.

The researched entry is satet, third member of the Triad of Elephantine, which already lists "Satis (Greek)" among her names.

Why this one hid from two detectors

Worth recording, because it is the third distinct way a duplicate has slipped through.

The consonant skeleton could not see it: satis reduces to sts, satet to stt. Greek nominative -s against Egyptian feminine -t is a real transliteration difference that the skeleton treats as a different name.

The census snippet could not see it either, because satet is not in the census at all — she entered the corpus through the Triad group expansion, so there was no snippet to compare against.

What caught it was the third detector added this batch: satet.md names Satis in its own "Also known as" line. The answer was written on the page the whole time. See finding C207.
