feat(propose,consume,tools): the type that declares nothing, and the prefix that is not a word

Browse source 
Three of round 9's four measured holes, each closed with a rule chosen on a
measurement rather than named as a limit.

`rtf` GIVES 0 SEGMENTS -> 6 of 6 AUTHORED TITLES over N = 4. The container has
no heading style, so the author's title is bold text. The grammar is markdown,
not `rtf`: the converter already writes that title as `**...**` in the same
output every office row produces, so no `rtf`-only heading form exists. Three
parameters were swept over 47 readable documents and ONE carried -- refusing a
line that ends in terminal punctuation takes false-positive lines from 9-12 to
1-2. A maximum title length (unlimited/40/60/80/120) and a
must-stand-between-blank-lines clause are both FLAT, so neither is in the rule.
The last false positive is closed by G1, the principle `_gate_outline` already
carries: recovery yields to declaration. False positives are then 0 of the 31
declaring documents by construction, and 0 of 27 on the corpus. Reach: 2 of 39
corpus documents, both `docx`, 0 of 33 `pdf` and 0 of 2 `xlsx`. Behind
`--bold-title`, default OFF pending the hit@8 measurement; the default bundle
is byte-identical without it.

BOTH ALTERNATIVES THE ORDER NAMED WERE MEASURED AND FELLED. A fourth hand-laid
fixture DECLARES heading styles in a stylesheet and the converter discards
them, emitting the same bold line -- so "read the declared headings out of the
markdown" has nothing to read. `rtf` -> `docx` -> markdown yields 0 ATX
headings on that same document, because the loss is in the `rtf` READER before
any writer sees the style. Fixtures are hand-laid in `make_k2_office.py` with
the fasit written first; they live in their own directory because Door B walks
a drop directory recursively and `k2-office/` reads its N off the listing.

THE PREFIX OVER-MATCH: THREE CANDIDATES MEASURED, ALL THREE FAILED ON ONE ROW.
Re-measured on the pinned 453-concept bundle with the control run first:
`under` occurs 79 times by equality and matches 172 by prefix, `undersjoisk` 0
and 172, `bilateral` 0 and 400 of 453, `standhaftig` 0 and 219. The two extra
known-negatives were FOUND, not chosen -- every 4-character prefix ranked by
document frequency, then a real word taken from the widest. A longer floor
(5-8), a coverage share (0.5-0.8) and a long-words-only floor (>= 8) each cost
row 1 its rank on the default bundle and the whole row on Arm B. Decomposed:
row 1's token `prisene` reaches its gold document through
`pris|sammenstilling` on four characters -- 0.57 of one word and 0.22 of the
other -- so the over-match and the wanted match are one mechanism.

THE FOURTH CANDIDATE IS THE ANSWER: the shared prefix must be a WORD the bundle
uses. `pris` is; `bila` and `stan` are not. `bilateral` 400 -> 0 and 512 -> 0,
`standhaftig` 219 -> 56 and 235 -> 33, every hit@8 row keeping rank 1 on BOTH
bundles. `undersjoisk` stops at 162 because `under` IS a word here -- a genuine
Norwegian morpheme, so that residual is a different answer, not a ceiling. ON
by default (`--no-stem-prefix`), pinned with its own known-negative on the
shipped bytes.

THE SHIM: a path importer holds the object `module_from_spec` made, and
`sys.modules[__name__] = _impl` never reaches it. Measured under both counting
methods -- 3 of 76 public names by `vars()`. One line copies the public names
into this file's globals; the dunder filter is load-bearing, because an
unfiltered copy overwrites `__name__` before the next line uses it as the alias
key. It restores attribute ACCESS and not patch-through, which is why the alias
stays. A CHANGELOG note under 0.7.0 and a shim docstring line say so, since
what the consumer asked for was the note.

Suite 1515 -> 1535.

# segment. A repair proposed on N = 1 is a repair fitted to one file, so round

#
# WHAT EACH ONE VARIES, and it is one axis each:
#
# -fet-alene the title is bold at BODY size, with no point-size change
# at all. Variant A (`krav-rikt-tekstformat.rtf`) sets its
# title bold AND at 16pt, so without this document a rule
# reading "bold" could be passing on the size instead.
# -fet-i-avsnitt a bold PHRASE inside a running sentence, which must NOT
# become a boundary. The document's own known-negative.
# -stil the container DECLARES heading styles (`\\s1`, `\\s2`) in a
# stylesheet. This is the control for the whole repair, and
# it is a control that FAILED in an informative direction:
# measured, the vendored converter discards the style and
# emits the same bold line, so "read the declared style"
# is not a route that exists for `rtf`. The fixture is kept
# precisely because it pins that.
#
# The bodies are deliberately short. These documents answer where a boundary
# is, not how much text survives -- variant A already carries the coverage and

"""A bold standalone line is a title where the document declares nothing else.
THE HOLE THIS CLOSES. Round 9 met `rtf` end to end for the first time and the
row came back at 0 of 0 declared headings, 0 concepts, 1368 of 1368 characters
in no segment, N = 1: the container has no heading style, so the author's title
is bold text, the proposer proposes nothing, and the document reaches Door B's
inbox as one flat concept. Content preserved, structure zero.
WHAT THE GRAMMAR READS, AND WHERE IT LIVES. Not `rtf` markup. The converter
already emits that bold title as `**Kravspesifikasjon for tunnelbelysning**` in
the SAME markdown the other office rows produce, so this rule is a markdown
rule and no `rtf`-only grammar exists -- the same shape of decision as the PDF
font reader emitting ATX rather than a PDF-only heading form. Bold INSIDE a
paragraph is `text **bold** text` and is not a whole line, which is the
discriminator the rule rests on.
THREE PARAMETERS WERE SWEPT AND ONE CARRIES. Over 47 readable documents (3
hand-built office fixtures, 5 in the operator's folder, 39 of the 43 corpus
files), with the false-positive denominator measured FIRST:
* a maximum title length (unlimited / 40 / 60 / 80 / 120 characters) is
FLAT -- identical counts at every value;
* requiring the line to stand alone between blank lines is FLAT -- the
converter already writes one paragraph per line;
* refusing a line that ends in terminal punctuation carries: false-positive
lines fall 9-12 to 1-2, and the four candidates it drops are
`er inngatt mellom:`, `Sted og dato:` and their kind -- sentence fragments
a contract's cover page sets in bold, never section names.
A parameter measured flat buys nothing, so neither of the two is in the rule.
THE GATE IS G1, ALREADY SHIPPED. One false positive survived the punctuation
clause: a corpus `docx` that DECLARES two headings of its own and sets one
later line (`EGENERKLAERING`) in bold. The repair is not a fourth parameter --
it is the principle `_gate_outline` and `fold_units` clause 2 already carry,
that recovery yields to declaration. A bold-title candidate is admitted only
where the document declares no heading of its own, which takes the
false-positive count to 0 of 31 declaring documents BY CONSTRUCTION.
WHAT WAS MEASURED AND NOT ADDED. `heading_reserve_applies` yields to an
admitted Arm D run as well as to a declaration, and that axis was measured
here before being left out: over all 4 documents that reach this rule, the
outline gate admits 0 runs and the reserve applies on every one. n = 4, which
is small; the axis is flat over it, so coupling this rule to `outline_run`
would add a knob no measurement asks for.
HONESTY LIMIT: the `rtf` row rests on hand-built documents, not corpus files.
The corpus contains ZERO `rtf`. Its evidence class stays `constructed`.

it, and the test below pins what it costs when it is off.

"""A path importer holds the module object, and `sys.modules` is not it.
WHAT WAS REPORTED, AND BY WHOM. `vegnormal-okf` reported after v0.7.0 that the
shim broke a caller importing it with `importlib.util.spec_from_file_location`.
Reproduced here, and it is not a spelling mistake: `sys.modules[__name__] =
_impl` replaces the REGISTRY entry, and a path importer already holds a
different module object -- the one `module_from_spec` made and `exec_module`
ran. That object keeps whatever the file's own globals ended up with, which is
four public names, while the registry entry has ninety.
TWO COUNTING METHODS, BOTH IN THE TEST. `vars()` gives 4 against 90 and `dir()`
gives 3 against 75; the numbers differ because `dir()` on a module is sorted
and de-duplicated over a different set. Asserting only that ONE name appears
would be green over a nearly empty set -- which is how the defect survived a
release -- so the test asserts the COUNT under both methods.
WHAT THE FIX IS AND WHAT IT IS NOT. One line, copying the implementation's
public names into this module's globals BEFORE the alias. It restores attribute
ACCESS. It does NOT restore patch-through: a caller who monkeypatches the copy
patches a binding the implementation never reads, and that is exactly why the
alias exists and why it stays. The dunder filter is load-bearing -- an
unfiltered `vars(_impl)` overwrites `__name__` with
`llm_ingestion_okf.consume` before the next line reads it, and the module is
then aliased under the wrong key.

"""The shared prefix has to be a WORD, or `bilateral` reaches 400 of 453.
THE FINDING, RE-MEASURED. `MIN_SHARED_PREFIX = 4` exists for Norwegian
compounding -- `vare|ne` and `vare|mottak` share a stem -- and it has a
known-positive in the suite. It also matches on four characters that are not a
stem at all. Measured on the pinned 453-concept bundle, with the control run
FIRST every time:
word equality prefix share
under (control) 79 172 38.0 %
undersjoisk 0 172 38.0 %
bilateral 0 400 88.3 %
standhaftig 0 219 48.3 %
The two extra known-negative words were FOUND rather than chosen: every
4-character prefix in the bundle was ranked by document frequency, and a real
Norwegian word was taken from the widest ones -- `bila` (400 of 453, through
`bilag`) and `stan` (219, through `standard`).
THREE CANDIDATES WERE MEASURED AND ALL THREE FAILED, each on the SAME row.
a. a longer floor (5, 6, 7, 8) row 1 falls 1 -> 2 on the default
bundle and 1 -> None on Arm B
b. coverage >= 0.5 / 0.6 / 0.7 / 0.8 every negative to 0, control still
88 > 79, and row 1 still falls
c. prefix only for words >= 6/8/10/12 only >= 6 holds the ranks, and it
fixes `bilateral` alone: 137 and
219 remain
WHY THEY ALL FAIL ON ONE ROW, decomposed rather than guessed. Row 1's question
token `prisene` reaches its gold document through `pris|sammenstilling` and
`pris|skjema` on the four characters `pris`. That is 0.57 coverage of the
question word and 0.22 of the document word -- so a coverage rule at 0.60 cuts
exactly the match that finds the price sheet. The over-match and the wanted
match are the same mechanism seen from two sides, which is why length and
coverage cannot separate them.
WHAT DOES SEPARATE THEM. `pris` is a word; `bila` and `stan` are not. The
fourth candidate requires the shared prefix to occur as a token in the bundle's
own concepts, and it is the only one that clears both criteria at once:
bundle bilateral standhaftig undersjoisk control ranks
default-20260912 400 -> 0 219 -> 56 172 -> 162 172 (1,1,1,1,1,None)
armB-20260903 512 -> 0 235 -> 33 174 -> 160 174 (1,1,1,1,1,None)
WHAT REMAINS, AND WHY IT IS NOT A CEILING BUT A DIFFERENT ANSWER. `undersjoisk`
still reaches 162 concepts, because it shares `under` with them and `under` IS
a word in this corpus -- a productive Norwegian prefix. `standhaftig` still
reaches 56 through `stand`. Those are genuine shared morphemes, and a rule that
cut them would be cutting the behaviour `MIN_SHARED_PREFIX` was built for. The
residual is a statement about Norwegian, not about the implementation.
HONESTY LIMITS: n = 6 questions, one rater, one gold set, and row 6 misses on
every bundle and every configuration measured so far. The three known-negative
words were chosen by this session from the bundle's own vocabulary, not by an
independent source. The vocabulary is the BUNDLE's, so this rule makes a
payload depend on the corpus the way `rarity_weights` already does.
