Three STS fixtures still carried the section titles and labels of one real
reference document, and three identifiers were copies of its codes with a
letter or a word swapped. They now describe an invented kitchen counter and
cookbook series: the titles, labels and descriptions of sts-identity.xml,
sts-inherit.xml and sts-empty-label.xml, the P350/P351 document codes, the
99-0001 delivery prefix and chapter 7 of the image and accounting corpora.
Generated fixtures are regenerated and the witness inventory's per-document
totals are identical before and after; only names and text move.

RED. Measured on R761 after the reader landed: non-whitespace preservation was
1 283 393 characters against the source's 1 283 395. Two characters, and a
percentage would have let them pass -- a ratio of 0.999998 reads like rounding.
Located by a prefix/suffix scan rather than a diff: the whole loss is one `x)`
marking a `<sec>` that carries a label and nothing else.
The mechanism is this reader's own. A label-only section holds its label as a
PREFIX for the body line beneath it, the way `li` is handled in the HTML
reader; when no body line follows -- the next thing emitted is the following
section's heading -- the pending prefix is overwritten by the next one and the
label never reaches the text.
`sts-empty-label.xml` is the case, hand-written and small: a lettered point
with a body, then one with none, then the next titled section.
pytest -q: 1 failed, 1566 passed, 1 skipped.
