"""What round 7 moved to the default, and the opt-out that reproduces the old bytes.

Three moves, each with its own acceptance measurement in
`docs/2026-09-10-k3-runde7-forste-spenn-og-rangeringen.md`:

* `--first-span-from-zero`, because 32 of the 32 corpus documents with a plan
  left their opening text in NO segment -- 9.18 % of the corpus.
* `--sheet-section-rows --keep-table-heading`, which were held back in round 6
  by a retrieval regression the third move removes.
* `tie_shared_rank` on the reading side, which is what removed it.

Every move keeps an explicit opt-out: a default a caller cannot turn off is
not a default, and a consumer needing the previous bytes needs a way to say so.
