Order 20260908T133512Z-139864689-from-.claude. First iteration of the
per-file-type directive (operator 2026-09-08 13:05Z), not the last. No
threshold is set: ratifying a bar is the operator's, and setting one inside the
work that produces the measurement would be fitting the bar to the number.
[skip-docs] covers README.md only, and it follows a precedent re-measured this
round rather than quoted: `grep -c` for outline-run, table-grid, Arm C, Arm D
and Arm E returns 0 in README.md and CHANGELOG.md, while --path-prefix, a real
interface change, has a CHANGELOG entry. The rule is "interface and behaviour
changes yes, arm flags no", and --unit-fold is an arm flag that defaults off.
CLAUDE.md IS updated, because its `okf build` bullet enumerates which arms are
off there and would otherwise become false.
FUNN 1, and step 1 asked for it: the reproduction broke. Arm E on HEAD is
byte-identical to the archive on 31 of 33 plans; the two that differ are 2 of 2
spreadsheets in the corpus. The cause is EXTRACTION, not segmentation --
56ae274 writes a workbook as pipe tables, and the sample's price sheet extracts
to 11 048 characters where the worksheet records 100 694, which is the figure
that commit's own message predicts. The consequence is a segmentation
regression against the reference: K3 position 3 went 3 concepts -> 1 under both
Arm D and Arm E, where the operator wants eleven. The mechanism is the orphan
check dropping the sheet heading once a table opens below it (propose.py:461),
already reported there as a ranking regression. Doors unchanged: 43 .err, 4
FAILED, extractable 39/43.
THE MATCH CRITERION WAS WRITTEN DOWN BEFORE ANY CELL WAS SCORED, and it stalls
at 7/12 on the literal calibration gate after three rounds, each revision
recorded. The five failures are not the criterion's: at every one it agrees
with the operator's own (a), (b) or free text and disagrees only with (c).
Column (c) is a RELATIVE judgement ("closest today"); the four K3 categories
are absolute. The only way to reach 12/12 is to define "correct" as "the
closest arm", which reads (c) back out of itself. The dominance gate, declared
in advance as the second reading, holds at 11/12.
ARM F is one rule with three clauses derived from the operator's three, not
twelve special cases, and it only MERGES or DISCARDS: a run of at least
CONTENTS_RUN same-level page-numbered headings is a contents list and goes; a
heading deeper than the unit level folds into its parent, extending the
parent's span; a table folds back into the shorter heading that introduces it,
keeping the HEADING's name. K3 first rater, n=12: 2 coarse / 5 fine / 0
duplicate / 5 correct -- best of four arms, ceiling was 4, two moved, nothing
regressed anywhere.
THE PAPER MEASUREMENT CAME FIRST AND FALSIFIED THE FIRST VERSION. Clause 2 was
letting rule:outline -- Arm D's RECOVERY of an integer numbering run -- vote on
the unit level, which took K3 positions 1, 7 and 9 to 3, 4 and 7 concepts
instead of 17, 34 and 11. A recovered numbering is a heuristic, not a level a
document declares, and the unit worksheet showed the operator ATX and dotted
headings only. Fixed with its own red test; 11 of 12 predictions correct after.
PER FILE TYPE, which is the directive: docx 3 of 3 (solved on this sample), pdf
2 of 8 (lags, unchanged by Arm F, and the remainder is decomposed per position
rather than left as one number), xlsx 0 of 1 (regressed, see FUNN 1). Outside
the corpus, n=1 each: pptx and odt byte-identical, rtf proposes nothing either
way, txt differs and exposes clause 2's fallback.
CONTENTS_RUN swept 1..5 and off. Distance prefers 1; three ships anyway,
because at 1 the body chapter "... i henhold til TEK 17" is deleted for ending
in a number, and no K3 cell differs between 1 and 4 -- the metric prefers a
value that provably deletes a chapter and cannot see the cost.
Whole corpus, all 43 through arm_run in ascending foreground chunks: 32 plans,
491 entries against Arm E's 679, 14 documents changed, 1 plan disappeared
entirely (three drawing-schedule numbers that clause 1 correctly reads as a
contents run) and that is reported rather than special-cased.
THE okf build MECHANISM IS REPRODUCED AND IT IS NOT DOOR B: cli.py calls the
proposer with no arm flag at all, so the shipped build path is Arm B. On a
tender PDF that means no boundary where Arm D finds nine and the reference says
nine. Largest per-file-type gap this round found; it is a default change and
therefore the operator's.
5 tests red first, 1373 -> 1379. ruff clean, mypy --strict clean on 17 files.
K2 consumer bundle unchanged: 1108 files, digest 9cd74519... with the flag off.
No bundle built, no version bump, no tag, no push.
