K2 on pptx/odt/rtf: the denominator, measured, 2026-09-04

Order 20260904T190727Z-589245685-from-.claude. Closes a declared gap — docs/2026-09-02-korpuskjoring-k1-k2.md already recorded pptx, odt and rtf as "denominator 0 — unmeasured by construction" in K2/trinn1. This report re-measures that denominator with ls/find against ground truth, per Verifiseringsloven ansikt 4 (a measured absence needs its query proven able to find, not just an empty result), rather than trusting the earlier doc's number as still current.

Ordered as two steps: measure the denominator first, then only run K2 if the denominator is non-zero. It stayed zero, so step 2 (K2 fidelity) was never started — no code, no test, no fixture, nothing to gate under the Iron Law.

Step 1 — the denominator

"K3-korpuset" is not a second directory. Both docs/2026-09-02-korpuskjoring-k1-k2.md (K1/K2, 02.09) and docs/2026-09-04-k3-arm-c.md (K3, 09.04) run their okf_corpus_run.py invocation against the same path: ~/corpora/okf-telling-20260829/K2/trinn1. There is no separate K3 corpus directory — the order's parenthetical ("samme kataloger K1/K2-målingene 02.09 brukte") confirms this rather than naming a second one. One directory, counted once.

CORPUS=~/corpora/okf-telling-20260829/K2/trinn1
find "$CORPUS" -maxdepth 1 -type f | wc -l          # -> 43
find "$CORPUS" -maxdepth 1 -iname '*.pptx' | wc -l  # -> 0
find "$CORPUS" -maxdepth 1 -iname '*.odt'  | wc -l  # -> 0
find "$CORPUS" -maxdepth 1 -iname '*.rtf'  | wc -l  # -> 0

format	files in K2/trinn1 (= K3's corpus)
pptx	0
odt	0
rtf	0

N = 43 matches the file count both prior docs report for this directory — verified here again with find, not carried over from STATE or a prior doc.

Known-positive control (the query can find, so the 0 above is a measured absence, not a broken query): the same directory, same command shape, a format known present:

find ~/corpora/okf-telling-20260829/K2/trinn1 -maxdepth 1 -iname '*.docx' | wc -l  # -> 5

5/5 found, exit 0. The pptx/odt/rtf queries above ran with the identical shape and returned nothing — an absence, not a silent failure.

There is also a K2/trinn2 directory (43 further files, byte-identical to trinn1 per docs/2026-08-29-telling-offentlig-prosjektkorpus.md § 6, sha256 equal 43/43) and a K1 directory (0 files on disk — K1 Skram was never downloadable, same doc § 5). Neither was part of the 02.09 K1/K2 measurement or the 09.04 K3 measurement, and the order scopes this re-measurement to "the same directories K1/K2 used" — so neither is counted here. Naming them is the whole of what this report says about them.

Sum across both named corpora (K2/trinn1 and "K3-korpuset", which are the same directory): 0. Per the order, that ends the work at step 1 — K2 for pptx/odt/rtf is not measurable on this corpus, and step 2 does not run.

Which public corpus has these formats

The order asks this report to name a public corpus that already has pptx/odt/rtf files, without fetching anything new. ~/corpora/ holds exactly one corpus directory (okf-telling-20260829), and no file anywhere under it matches *.pptx, *.odt or *.rtf:

find ~/corpora -iname '*.pptx' -o -iname '*.odt' -o -iname '*.rtf'   # -> no output, exit 0

No public corpus with these formats is on hand. Naming one would require new research (a new download, a new search) — out of scope for this order, which asked only to check what already exists locally. This is reported as "not verified", not as "no such corpus exists" (Verifiseringsloven ansikt 4): absence of a locally-known example is not evidence none exists publicly.

Bundle integrity

No bundle was touched — step 2 never ran, so there is nothing to materialize. The only operations against the corpus were read-only find commands. As a sanity check anyway (the aggregate-hash trap from docs/2026-09-04-cid-andel-k2.md — sort needs LC_ALL=C or the hash is an artifact of locale, not content):

LC_ALL=C find ~/corpora/okf-telling-20260829/K2/trinn1 -type f -print0 \
  | LC_ALL=C sort -z | xargs -0 shasum -a 256 | LC_ALL=C sort | shasum -a 256

Before and after the counting commands above: both runs gave 4f093df27adb081c99c3e08ad12aab1e56f4429bcf900bdf80bc01cf21e104ce. Identical — byte-unchanged, as expected of read-only find/ls.

Result

pptx, odt, rtf in K2/trinn1 (the same directory the K1/K2 and K3 measurements used): 0 files in both named corpora — K2 for these formats is not measurable here. No K2 step 2 work was started. No public corpus with these formats is currently known locally; identifying one is new research and out of scope for this order.
