`uv sync --frozen` resolved ruff 0.15.22 and the tree read clean. A loose
install resolves 0.16.6, under which the SAME untouched code reports 148
findings -- 4 more than round 9 counted, because this round added four files.
All of them are new rules rather than new defects: 0.16 widened the default
rule set to whole families (YTT, ASYNC, PL, ISC, C4, UP, B, SIM, FURB, ...).
(`[skip-docs]` is for CLAUDE.md, which a lint-configuration change does not
reach. README's developer section IS updated in this commit.)
THE DEFECT IS NOT THE 148, IT IS THAT NOBODY CHOSE THEM. `[tool.ruff]` set only
`line-length` and `target-version`, so the acceptance was ruff's default, and
the tree stayed green only as long as the lockfile froze an old ruff. `select`
is now written down: `E4`, `E7`, `E9`, `F` (the historical default), `I`
because this tree already keeps imports sorted, and `RUF100` so a `noqa` that
has stopped meaning anything is caught rather than left as decoration. Pin
`ruff>=0.9` -> `ruff>=0.16.6,<0.17`.
Per rule, before -> after: RUF100 50 -> 0, I001 20 -> 0, ISC004 19, PLW1510 8,
C408 8, EXE001 6, RUF007 5, PLE2515 4, UP031 3, B017 3, and fourteen more with
2 or fewer -- the families out of the declared set are 0 by selection, and 148
is the number to start from if they are adopted, which is a separate decision
and not one to take inside a version-pin commit. 57 were auto-fixed; one E402
was reintroduced by the import-sorting fix merging a block away from its
`noqa`, and got the directive back rather than a bare one.
`S` IS MEASURED OUT, NOT ASSUMED OUT: it reports 2657 `S101` on a suite whose
every assertion is an `assert`, and `S603` flags 19 subprocess calls of which
one was ever marked -- selecting it buys 18 suppressions and no defect. Two
`noqa` directives naming non-selected rules were dropped with that reason
recorded in the configuration instead.
THE TWO FILES 0.16 WOULD REFORMAT ARE MARKDOWN, NOT PYTHON: `README.md` and
`docs/2026-09-08-blindsone-below-k-k2.md`. 0.16 formats fenced Python inside
markdown, and both blocks are RECORDS -- the second is a quotation of
`COST_VOCABULARY` as it stood when that measurement was taken. Reformatting a
quotation makes it stop being one, so markdown is excluded from the formatter
and `ruff format --check .` stays in the acceptance over `.py`.
`tools/okf_consume_measure.py` is fenced by the order as run-not-edited, so its
three findings are exempted by path with the reason and the debt named, and its
bytes are untouched.
THE LOCKFILE TRAP IS CLOSED, NOT AVOIDED. `uv.lock` predated the `[ocr]` extra,
so any unlocked resolve wrote that extra's transitive tree back into it -- 681
insertions over 4 deletions, twice now, and round 9 recorded the cause as
`uv run` OUTSIDE the project when it is `uv run` without `--frozen` INSIDE it.
The relock is complete for every declared extra (703 insertions, 26 deletions),
and measured after it, an unfrozen `uv run` leaves the file alone.
`ruff check src tests tools`, `ruff format --check .` (0.16.6), `mypy src` over
21 files and 1535 tests, all green.

`docs/2026-09-04-k2-pptx-odt-rtf.md` measured the corpus denominator for
these three rows at zero, so K2 for them was unmeasured rather than
passing. This measures them on the synthetic set committed in `a7b050b`,
whose hand count landed BEFORE any of these numbers existed.
Coverage 59/59 and pairing 20/20 for all three, standalone and product
alike, where "product" is scored off the persisted concept in the bundle
rather than an intermediate. The instrument's own denominator, derived
from each file's XML or stream, agrees with the hand count on all three:
59 strings, 20 pairable. Door B over the fixture directory persists 3/3
with nothing quarantined, rejected, failed or skipped, so K1b holds at
3 = N. There is no sub-100 % cell to explain, and that is a result about
three documents we wrote, not about the formats.
THE NEGATIVE CONTROL IS WHAT MAKES THOSE FIGURES MEAN ANYTHING. Removing
one label and its value from each converted text moves every row to
57/59 and 19/20 -- exactly the two strings and the one pair taken away.
`tests/test_fidelity.py` carries that control per reader, so it cannot
rot into a claim.
The order names `okf_fidelity` as the instrument and the instrument
refused all three types (`no source-string reader for '.pptx'`), so step
2 could not run without readers for them. Added here, stated in the
report as sitting outside the order's enumerated fence: this is the
measuring instrument, not extraction code. `extract.py` is untouched and
every `_EVIDENCE` row still reads `unmeasured` -- three synthetic
documents in one house style are exercise, not coverage, and the suite
asserts the rows are not promoted.
Two converter findings, reported and not fixed, both exit code 0 with no
warning. RTF cell paragraphs without `\pard\intbl` are read as each row
nested inside the previous one, 2076 characters where 117 were expected.
And the `\uN?` unicode escape -- THE FORM WORD EMITS -- loses the
character after it: `A\u248?BC` reads back as `AoC`. Any Word-produced
RTF carrying Norwegian letters loses one character after each of them,
silently. That is now a named limit of the `rtf` row rather than an
unknown.
Pandoc 3.9 and the host's 3.10.2 produce byte-identical output for all
three fixtures, so the numbers are not sitting on a version-fragile edge.
`~/corpora/` was neither read nor written; N there is still 43.
Suite 1141 passed, `ruff` clean, `mypy --strict src/ tools/` clean over
25 files, all after `git add`. Regenerating the fixtures leaves
`git diff --quiet` clean.
