P18's round 2 ended with two VALIDATED proposals whose affected_item codes
were ordinary words from a road standard's prose -- impulsventilator (4 of
270 N500 documents) and bituminoest baerelag (4 of 1133 N200). Both are
grounded in P7's sense and neither is inert in P18/B1's sense; they are simply
not identifiers of a cost line, and the gate had no stage that could say so.
Known positive MEASURED, not asserted: replayed offline against the bases
those runs were given, both come back Rejection naming the denominator.
IDENTIFIER_FORMS moved from generate.py to validator.py: they now drive both
P8's report and this gate, and two copies of "what an identifier looks like"
would let the two disagree about one run's own input.
B1 -- two new forms, transcribed from measurement. R761's requirement numbers
are bare dotted numbers and all six refs in kontrakt-sorasen's fasit are of
that shape, which neither pre-P19 form matched: r761's whole offer was 3
identifiers over 6.5 MB, and is now 2332. The FIRST form was widened in the
same pass because B2 made these forms decide prose vs identifier, and this
repo's own ENERGI-TOTAL-EL matched none of them -- a gate may only be wrong in
the direction that admits too much.
Three things keep the gate from being a rule about shapes: the generality
guard (it fires only where the input offers forms), the baseline exemption
(stage 0 has already ruled that code real), and full-matching.
Honesty limit, measured and given its OWN arm: a decimal and an R761 process
number are typographically identical, so the form counts both. P8's existing
"bare numbers" arm is narrowed to bare INTEGERS accordingly.
Measured over all nine round-1+2 outboxes: 26 of 36 codes are prose.
Load-bearing measured (22 arms), four mutations all red against the whole
suite (16 / 10 / 1 / 2), green control 1734/5 and the golden byte-unchanged.

P18 parts B and C (order 20260914T105139Z).
B1 -- stage 0b. P7 made it `item.code in grounding`: plain containment over
ONE concatenated string. P16 ran it against a delivered corpus and measured
what containment cannot tell apart: the falsification arm a4-indeksregulering
put 250 000 NOK on a single cost line coded R761 -- the knowledge base's OWN
NAME, carried by all 2 756 of its concept documents -- and the whole gate
said validated (stage 0 skipped, un-anchored run; checker approve).
The grounding is now carried as the DOCUMENTS it is made of (validator.
Grounding), not as a blob. A structure and not a second argument beside the
text: the boundaries and the text are one fact, and .text is derived, so the
gate and P8's report measure the same characters. run.py composes one
document per concept file where the base is already walked; generate.
_grounding_text folds each cost line in as a one-line document.
N and A are MEASURED, not chosen (14.09, four mounted vegnormal bases):
- every must_cite ref and mandate affected_code in the four context sets --
shortest real identifier is FOUR characters (12.1, 52.1), so N = 3 sits one
below the measurement and cannot refuse anything measured;
- document frequency of every code-shaped token per base -- 1 692 distinct
and NOT ONE reaches 5 %. Highest anywhere 6/446 (1.35 %), highest a fasit
names 3/446 (0.67 %), R761 2 756/2 756 (100 %). A = 0.05 therefore sits
3.7x above the highest real token and 20x below the defect.
Length is NOT what makes the defect inert (R761 is four characters); the
share is. And a share is not a measurement without a denominator big enough
to take one (ansikt 4): one of three is 33 %, so an ABSOLUTE floor of 10
documents gates it. Highest absolute count any real identifier reaches is 6,
and every fixture in the repo is far below 10 -- which is why every pre-P18
gate is UNTOUCHED by this rule rather than exempted from it. Grounding.of
(one document) can never reach the floor by construction.
The refusal NAMES the denominator ("appears in 2756 of the 2756 documents
this run was given"), because Step 5 feeds that reason verbatim into the next
attempt's prompt: a proposer told only "ungrounded" answers with another
token of the same kind.
B2 SPIKE (measured, NOT built) FELLED the order's own alternative: option (b)
"ground in what the run OPENED" was run over P16's 16 code rows -- R761
stands in every OPENED document too, so (b) would NOT have caught the defect,
while B1 makes it inert and still grounds the real process line 65
ASFALTDEKKER (29/2756 = 1.05 %). (b) is not a substitute for B1.
C1 -- --docs-dir is optional once --bundle-dir is given (P16 FUNN 2). On the
bundle path docs_dir is never read: retrieval, the chunk tool and the "no
citable content" check all live in the road branch. Bound ONCE from
--bundle-dir, which is byte-identically what the README already tells an
operator to type by hand. NOT the "--docs-dir omvei": no such path is opened
and the road branch still refuses without a real --docs-dir (own arm).
C2 -- the judge's snippet arm counts only under citation_scope == "narrowed",
as (a) already does (PM decision, P16 s 6.2). P16's reason for (b') being
clean -- snippets are bodies while ref/title live in frontmatter, 0 of 446
n100 bodies -- holds for "Krav 4.1.2-1" but NOT for R761, where a process
number like 12.1 stands in the bodies. Under a whole-base citation list that
mark was "cited" before any model call.
tests: test_inert_identifier_loadbearing.py (7 arms; known positive is P16's
OWN artefact replayed against the base that run was given, known negative is
26 of 26 fasit references still grounding), test_docs_dir_optional_
loadbearing.py (5 arms). test_stress_judge_loadbearing.py's snippet arm split
into narrowed/whole-base -- the pair is the discriminator, same snippet, same
mark, only the scope differs. The grounding tests migrate from str to
Grounding.of (the honest reading of a caller that declared no boundaries).

P7 is right and landed, but re-measuring it exposed a consequence no row stated: with the gate
live, 29 of 29 cost codes in 13 of 13 delivered proposals fall across the three free recordings
(PM's denominator; 14 of 14 in 8 proposals on the PARSEABLE one -- the five blobs that separate
the numbers are refused by pydantic's `claimed <= total` and never reach stage 0b). All 29 were
invented, so the gate is right; but a gate that always refuses is as useless as one that never
does.
The cause is that the PROMPT asks for something the input cannot supply. `_build_messages`
requires each affected_item to "restate a cost line as the project's price schedule already
carries it", while K2's delivered input carries 9 occurrences / 2 distinct code-shaped tokens --
`SHA-01`/`SHA-10`, both document numbers off a page footer -- and `derive_cost_baseline` refuses
the base outright. There is no cost line in it to restate.
`GroundingOffer(chars, identifiers, cost_lines)` reports it. The PAIR is the diagnosis: "50
identifiers, 0 cost lines" says what neither number says alone. A REPORT, never a gate -- it
blocks nothing, because a blocking requirement IS `--require-cost-baseline` (F4/D-3, opt-in,
untouched), and `_ground_against_input` is untouched.
The callsite is MEASURED, not chosen: `generate.py` composes the grounding per attempt, after
`await _fetch_parsed`, so a report there could only speak once an attempt had been paid for;
`run.py` binds both halves above the `--live-dry-run` cut and before the first `debate.run`, so
the FREE trip says it. `delivered` is bound ONCE and the same variable feeds the report and
`_evaluate`; the report composes THROUGH `_grounding_text`, the gate's own composer.
A pattern is admissible here and not in the gate, and that is the difference between a report and
a falsifier: an unknown form is a token left uncounted -- an under-count, never a false rejection.
The forms are transcribed from the measurement; bare numbers are excluded with the number
(46 394 / 2 117 in K2). `grounding_offer_notice` is the ONE renderer and is silent when the run
CAN anchor -- omission, never an empty row.
Load-bearing MEASURED (tests/test_grounding_offer_loadbearing.py, 12 arms), nine mutations all
red against the WHOLE suite + green control 1570/5 (from 1558/5, strict superset, 0 removed) and
