feat(propose,consume,profiles,importer): recovery yields to declaration, and 9 % of the corpus that was in no segment

One rule explains every remaining `pdf` miss on the twelve-position reference:
where a document DECLARES headings, Arm D's RECOVERED headings are the whole of
the excess, and every declared one is a unit the reference wants. `--outline-gate`
admits recovery only where the document declares none of its own, plus any one
recovered heading covering OUTLINE_SHARE (0.20) of the text. It is `fold_units`
clause 2's own principle moved from voting to admission, and it filters at
ADMISSION so the text a removed mark opened is carried by the mark above it --
the post-filter form scores identically on all twelve positions and loses that
text, which is why only one of them shipped.

`--outline-gate` and `--drop-wrapped-outline` become the package default, one
decision because neither carries the reference alone: `pdf` 2 of 8 -> 5 of 8
alone, 7 of 8 together; the sheet 5 of 12 -> 10 of 12; `docx` unchanged at 3 of
3. Each keeps an explicit opt-out. The bar the move had to clear was not the
reference: hit@8 on a K2 bundle built with it holds 5 of 6 at ranks 1,1,1,1,1,-,
no row losing rank 1. `--sheet-section-rows --keep-table-heading` reaches 11 of
12 and does NOT ship, because on a bundle built with it row 1 falls rank 1 -> 2.
Cost to a consumer is a re-run: 492 concepts / 944 files -> 425 / 810.

DOCUMENT_PRIOR_EXPONENT makes the document prior sublinear (total/n**0.5). A sum
measures size and a density is diluted by every unit carrying none of the
question, so a document split 1 -> 12 lost its prior by 12. Swept over five
values on 18 rows it is at least as good as the delivered density everywhere and
strictly better on three. Stated plainly: end to end it moved NOT ONE hit@8 row
on any of four bundles, so it did not solve the knot it was adopted for -- what
did is that the `pdf` gain never needed `--sheet-section-rows`.

`--first-span-from-zero` is off and repairs a measured loss found while chasing
one position's 940 characters: 32 of the 32 documents that get a plan leave the
text above their first concept in no segment -- 159 704 characters, 9.18 % of
the corpus, 45 841 from one document. It changes nothing on the reference. Off
because it moves the first span of essentially every bundle with no hit@8 number
behind it yet.

vegnormal-okf FUNN 2: SPEC section 8's own star row parsed as prose, so every
concept behind one was unreachable to the section 9.2 walk. `IndexPolicy.also_reads`
carries it for the SEGMENTED profiles, read-only, after the emitted pattern
misses -- the asymmetry `sources` already has. DEFAULT and STRICT_V1 untouched (O2).

vegnormal-okf FUNN 1: Door C's own outcome was refused at exit 1,
`bundle_id_missing`. `import_bundle` now takes `root_frontmatter_values`,
keyword-only, rendered before any disk mutation, written only when the index is
created -- Door B's mechanism and ordering.

Report: docs/2026-09-09-k3-runde6-outline-gaten-og-prioren.md.
Suite 1478 passed (1449 before), ruff and mypy clean.

+"""The bundle the DEFAULT build produces, pinned where a regression goes red.
+
+`tests/test_okf_consume.py` pinned hit@8 against the Arm B bundle alone -- the
+configuration `okf build` stopped emitting on 2026-09-08. A published number
+measured on a bundle nobody produces is a number that cannot regress, so the
+guarantee it looks like was never held by anything.
+
+This file pins the CURRENT default: `--outline-run 3 --table-grid --unit-fold
+--drop-wrapped-outline --outline-gate`, the configuration round 6 moved the
+default to on 2026-09-09 after measuring hit@8 on exactly this bundle.
+
+The gold set is LOCAL-ONLY and stays that way: no question and no
+`gold_document` is reproduced here, and a row is named by its INDEX, the way
+`docs/2026-09-07-okf-konsumskill-maaling.md` already names them.
+
+The bundle itself is a build artefact, not a fixture: it is 810 files of a
+consumer's corpus and this repository is public. Absent, these tests SKIP with
+the command that rebuilds it -- "not measured", never zero.
