docs: remove what this repository published about a consumer's corpus

Operator decision 2026-09-21: nothing from that consumer's collection goes out
on the public remote. The NAME stays where it is already published -- it is a
consumer of this library, named as such, and removing it would mean rewriting
published history, which this repository does not do. What goes is everything
that describes their CONTENT.

Removed across README, CLAUDE.md, CHANGELOG, four dated reports, the
consumption contract, three source modules and three test modules: their
corpus's document and page counts, the concept count of a bundle built from
it, the byte figures of a payload built from it, the question and fasit counts
and recorded score of their evaluation set, a bundle id with two content refs,
an order id naming them, and a path into their repository.

Kept, because the argument survives without the corpus: RATIOS and
percentages. A ratio is the finding -- a withheld list that is 65.5 % of a
payload is a defect at any corpus size -- and it discloses nothing about how
large anyone's collection is. Where a claim lost its denominator it now SAYS
so rather than quietly reading as unmeasured: the gate-refusal limitation in
the README states that the corpus and its counts are deliberately withheld and
points the reader at their own build, which is the number that binds them
anyway.

One integrity pin is kept and named here rather than left to be found: the
retrieval gate still pins that set by sha256, because the pin is what refuses
a self-written file in the right shape, and a checksum discloses nothing about
what it checksums. Its recorded SCORE is gone -- that was their figure about
their own corpus, and the row now says so instead of restating it.

The known-positive constants move with the contract document, as they must.
Suite green, 2372 passed.
