Row 7 left three mutants standing after v1.1 (11 of 14, bar 13): the passage
signal reading no body, the field signal weighing no title and no path, and a
flattened fusion (bm25.RRF_K = 10 000). Each switches off a mechanism the
default ranking runs, and each moved 0 ranks, because every synthetic concept
was short and opened with its own title -- none of the three ever decided a
delivery here.
Three bundles, one per mechanism, and one pinned set (set-mechanisms.json):
- PASSAGE: a long concept answered in one window of its body, against ten
short concepts whose titles carry the question's words. Rank 1; with no
body windows it falls out of k (class b).
- PATH: a concept named by its path alone, against ten decoys denser in the
body. Rank 4 at k = 6; with no title/path weight it falls out of k.
- FUSION: gold 1st in the passage signal and 21st in the field signal, one
decoy 10th and 11th (rank sum 19 < 20). At RRF_K = 60 the gold leads, and
it keeps the lead through K = 180 (measured in steps of 10); flattened, the
decoy wins k = 1.
Chose separate fixtures over one combined one because each fixture's comment
can then name the single mechanism it pins. Verified per question against all
14 mutants: no previously felled mutant is lost. src/ is untouched, MUTANT_BAR
and the roster are unchanged, the corpus pin moved with the corpus.
Gate: rows 1 and 6 go 10/10 -> 13/13, row 7 11/14 -> 14/14 GREEN, rows 2/3/4
unchanged, GATE RED: rows 5, 8. Suite: 2444 passed, 1 skipped (+3), measured
with FORCE_COLOR unset -- with FORCE_COLOR=3 in the environment Python 3.14
colours argparse help and test_each_arm_flag_carries_its_attribution fails,
independently of this change.

PM's J10 and J8. Two mechanisms, one per attack, and neither is a pin a
capability session can edit in the same breath as the code.
J10 -- THE DENOMINATOR IS THE SET'S. `Unit` now carries the class its question
DECLARES. Row 2's denominator is the misses plus every forced fixture that
came back a hit, and row 3's is every unit whose set declares a withheld class
(b, c, e -- (a) is not in the bundle and (d) was delivered, so neither can
carry a printed reason) plus whatever the run withheld besides. A fixture that
stops producing its declared class is a BROKEN PREMISE, printed as one, and it
counts against its row: at `k = 32` row 2 stays RED with its denominator held
and row 3 keeps 5 units where it had shrunk to 2 and called that green.
J8 -- THE ROW CARRIES A KNOWN-POSITIVE. With `--source-quota` off, every
printed reason is true; that reading is not a lie, it is an empty measurement,
and row 3 must say so rather than print `6 of 6 GREEN` beside row 1 falling to
8 of 9. A set may now declare `source_quota_in_force`, and the row is NOT RUN
for such a set when the default cut and the quota-off cut deliver the same
concepts everywhere.
THE CONTROL'S OWN PREMISE WAS MEASURED FIRST, and it was false where it was
first put: over the five existing sets the two cuts deliver the SAME concepts
(the quota is topped back up), so 52 labels move `source_quota_exceeded` ->
`below_k` without one delivery changing. `set-quota.json` is the set where the
quota genuinely decides -- measured, `oversikt-08` is delivered without the
quota and withheld with it, and the fasit `svar/broennproeve` is delivered
only with it -- so the requirement is declared there and nowhere else. It
survives the honest fix, which changes labels and not the cut.
Rows 1 and 6 go 9 of 9 to 10 of 10: one added fixture, one added hit, both
green before and after. Rows 2 (7 of 7), 3 (2 of 5), 4, 5, 7, 8, 9 and the
verdict `GATE RED: rows 3, 4, 5, 7, 8, 9` are unchanged. 52 passed.

One command, one exit code, and no capability: nothing here changes the
ranking, the fusion, the tokenisation or the cut. For a frozen question set
against a bundle it asks how many of N measurement units the payload carries
the fasit for, gives every miss exactly ONE class, and asks the thing the
payload does not do at all -- say so when it does not know.
Today, on the synthetic corpus this repository generates and the five sets it
ships pinned by sha256: rows 1 (9 of 9), 2 (7 of 7) and 6 (9 of 9) green;
3 (2 of 5), 4 (3 of 6), 5 (0 of 1), 7 (11 of 13), 8 (not run) and 9 (0 of 6)
red. GATE RED, exit 1.
- Row 3 is the finding to read first. In a bundle built from ONE source
document, every concept past the first two carries that document's
`source_file`, so a concept the RANK had already lost is withheld as
`source_quota_exceeded`. The truth is decided by the SAME cut run without
the quota -- PM measured the same lie on 13 of 25 real misses 2026-09-17.
- Row 4 is the second. No payload key says "this bundle does not answer
that", so the only honest reading today is `delivered == 0`; three of six
controls come out right and the three that do not get eight excerpts and no
statement. A control the bundle DOES answer must come back unmarked, or the
marking says nothing, so both directions sit in the same row.
- A miss has exactly one class -- (a) not in the bundle, (b) below k, (c) cut
by quota or budget, (d) delivered without the citation, (e) other -- and
each is FORCED by its own fixture. An unplaced miss takes the row to 0 of N.
- The judge opens the bundle. Every concept is read off disk before a payload
is built, a delivered excerpt whose text is not the concept file's bytes is
not a hit, and the two title forms come from `quality` rather than being
written a second time.
- FELLED means a row got WORSE, never merely that something changed: removing
the quota makes row 3 green, and counting that as a kill would credit this
gate with a check it does not have. The two survivors are reported with what
they measured -- the document prior dead and RRF_K flattened each moved 0
ranks and 0 deliveries on these fixtures -- and with a mechanism for each.
- Rows 8 and 9 are never green by leaving something out. The three real sets
are read from path + sha256 and never committed: a gold set names a
consumer's documents and this repository is public. K2 is 0 of 6 because the
gold set exists nowhere while its bundles do.
Denominators re-measured against the sources 2026-09-19, and all four hold:
wiki 20 questions / 29 fasit entries (sha 972d0f57...), R761 8 (S1-S6 + KP +
KN), vegnormal 32 questions / 43 must_cite, K2 6. PM's 45 of 70 is itself a
mixed sum -- wiki at question level, vegnormal at citation level -- so this
gate carries it labelled as recorded and never sums the two granularities.
46 tests, each failing row driven both ways through inputs rather than by
editing the row. No network (the socket guard is fired before its silence
counts), no private corpus, no clock.
