docs(881): a quotation that resolves nowhere, and a paragraph contradicting the one above it

Two more in the same class, both in prose this branch wrote.

The calibration paragraph quoted `post-review-verdict.sh` as asserting "the
absent-entry check catches every case on its own". That string occurs in no file:
the comment wraps it across a line break at `catches`/`every`, so `git grep` for
it finds exactly one hit - the record asserting it. That is ersatztv#812's second
defect reproduced inside the record written to end it. Paraphrased without quote
marks and pinned to lines 316-317 at `efadbec29`, which is what this record's own
proposal-2 clause prescribes for a quotation that cannot be checked.

The closing paragraph called the scan's hits "the remaining population" and "a
backlog", three paragraphs after establishing that both figures are CANDIDATE
counts and that reading them as a backlog of real claims overstates them. The
closing text now says what is actually known: a place to look, with nobody having
established how many are claims.
