Checked against the real class through tectonic, on the minimal document and on a corpus paper: page one goes straight from the affiliations to the abstract's own text.

occurrences of "Abstract" on page 1
reference (real revtex) 0
gotex 1

The generic \abstract (latex.go) centres one, which is right for article and wrong here; #354's capture carried it over along with the rest.

Measured

Σ|err| 326 → 326 (+0), glyphs −104 — thirteen revtex papers times the eight letters of "Abstract", exactly. No paper loses content.

What first looked wrong, and was not

On the rendered page the abstract looked left-aligned where it should be a centred block. It is not: ours sets it at x = 111.85pt against the reference's 117.76pt, six points apart — a short line in a narrow measure simply sits at its left edge in both. pdftotext -bbox is what turned "that looks off" into "the edge is right and the heading should not exist".

An image says where to look; only a measurement says what is wrong.
