test(R-110): remove the Scenario A marker — proof complete

Scenario A: pushed to main without moving the tag; the served bytes stayed
byte-identical (sha 2f859555…) and the marker never appeared, while the website
tree advanced to the new commit — both halves of the split in one observation.

Scenario B: moving the tag published it (~40s, sha ea2b4aa9…, marker present);
moving it back rolled it back to exactly the pre-publish sha with the marker
gone. The website returned 200 throughout.
