K3 round 3, order 20260908T170037Z-3622420612-from-.claude, plus the PM
injection of 17:55Z carrying the operator's D3 answer.
TWO NEW RULES, both OFF by default.
`--sheet-section-rows` cuts an open table block at the rows that label its
sections: a RUN of at least three rows whose first cell is a bare numeric
label. It is the first rule here that opens a span INSIDE a table, and the
opposite direction from Arm E -- that arm decides how far a block extends,
this decides where it is cut inside. The spreadsheet is the one file type no
arm had ever moved: 1 concept -> 12 on the priced sheet, of which 11 are the
reference's 11 cost groups. The run guard buys exactly three candidates on the
corpus (the rows stating a computation basis), and each section carries its
own `source_sheet` + `source_rows`, verified on the artifact.
`--drop-wrapped-outline` declines an outline candidate whose line continues
onto the next one. Round 2 falsified the LENGTH axis on this case; this one is
not about size. Over the 12-document sample it separates 8 of 34 candidates --
the quoted regulation paragraphs and the risk-table rows -- and none of the 26
the operator kept. Position 4: 4 concepts -> 1, the reference. The cell is
`treffer` by count and lossy by bytes, and the report says so.
Whole corpus, one cached extraction: 1 of 39 documents changes under the first
rule (0 of 32 pdf, 0 of 5 docx), 5 of 39 under the second (all pdf). Arm B and
F2 are byte-identical against a frozen c3b645b, both halves by `diff -r`.
THE `okf build` DEFAULT MOVED, and this is the operator's decision executed,
not a side effect: no flag now means `--outline-run 3 --unit-fold`. Each arm
keeps an explicit opt-out (`--outline-run 0`, `--no-unit-fold`) and the pair
reproduces the pre-move bytes exactly. The proposer's own defaults do NOT
move: they are what the goldens and every published reproduction block are
pinned to, so the two layers now disagree on purpose and `cli.py` says where.
Two shipped expectations moved with it and both are stated in place. MEASURED
AND REPORTED BACK: the configuration made default scores 2 of 12 on the unit
worksheet, `docx` 0 of 3 -- Arm F's published 5 of 12 was measured with
`--table-grid` ON, and without it the fold has no joined table to fold.
Position 1 is declined for the second round on the axis the order named: 3 of
3 recovered chapters have body under them, so "heading-on-heading" separates 0
of 3.
The K2 ranking control round 2 could not measure: two bundles from frozen
c3b645b differing only in `--keep-table-heading`, 2 of 1108 files apart. The
priced concept ranks 96 of 629 in BOTH and is delivered at rank 10 in both, so
the flag buys 35 payload bytes and zero rank positions. Round 2's prediction
is falsified: the concept's NAME was already restored by the orphan-name
inheritance; the flag adds the heading LINE.
The stale S7 literal is restated where it stood (`c759a657...`, 171 614 B,
re-measured on this HEAD), so the next order cannot inherit the superseded one.
1397 -> 1414 tests. Report: docs/2026-09-08-k3-runde3-per-filtype.md.

A concept named its source file by basename and, when segmented, carried a
`source_offset` into the text THIS LIBRARY extracted. Following that pointer
needed the corpus directory, the extractor and its exact transitive version --
none of which the bundle carries. Hand-walked on a real K2 concept: six steps,
four of them requiring knowledge from outside the bundle, to learn that a
requirement sits on pages 12-13 of a 20-page document.
The address is spec's: `sources: [{ resource, title }]`, where `resource` is
the dropped file's inbox-relative path (SPEC v0.2 5.1:303-306 -- "an absolute
URL, a bundle-relative path, or a path into a `references/` subdirectory").
The locator is ours, and it has to be: 5.1 has no field for a place within a
resource, and the pinned guard (1.3.0) rejects every route to putting one
inside a `sources` entry -- a non-allowlisted key by name, a nested flow list
as "scalar leaves only", and quoting as an unsupported form. So the locator is
top-level keys shaped like `source_offset`, and a path carrying a flow
terminator is refused fail-fast rather than mangled.
The unit table is built AT EXTRACTION, where the extracted text and the
original's structure are known to agree: pdf -> `source_pages` from
pdfplumber's own page numbers (a page that yielded no text does not renumber
the ones after it), xlsx -> `source_sheet` + `source_rows`, everything else ->
`source_lines`. `source_offset` stays.
Two measurements changed the design before it shipped. A `paragraphs` key for
docx would name a number the document does not have: `<w:p>` counts of
108/27/65/176/57 against converted-markdown lines of 75/33/67/144/63, not one
pair agreeing -- so the key is `source_lines` and says what it indexes. And an
empty spreadsheet row renders exactly like a table separator: the content-based
rule ate 8 empty rows on the K2 price sheet and reported its last row as 92
against a workbook that says 100. The separator is now found by position, and
`tomrad.xlsx` keeps that red.
One profile moves. `provenance` is a policy object, `None` everywhere but
`SEGMENTED_OKF_V0_2`; the other five shipped profiles are byte-identical.
K2 rebuilt from a frozen src copy: 629 concepts, 1108 files, name set identical,
0 ids moved, 479 files byte-identical, 629 changed and 0 lines removed anywhere.
629/629 now carry an address and a locator. New ref
`sha256-tree:665563a2f74423fcbcc8e4f0b0954ee73b73985ac0418de4f6987bd162a1f7c8`;
`2f82fcfe...` is stale. The pre-pass payload does not grow by one byte
(209 092 B before and after, 18 changed lines: the ref and eight per-concept
digests) -- because an excerpt carries the body, not the frontmatter, which is
also why the consumer still cannot cite "file X page 12" from a payload alone.
