`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.

run() parses the plan before building anything and parses its own
verdict after. Only the first failure is the operator's file.
The second is reachable: an empty --adjudicator produces a verdict the
grammar refuses ("adjudication field 'adjudicated_by' must be a
non-empty string"). The plan parsed fine; the fault is in what this
command stamped onto it.
Catching SegmentationError at the top of main() -- the previous commit
-- caught both raise sites and printed "malformed plan" for each. On
this path that is a clean, confident, WRONG diagnosis: it sends the
operator to fix the one artifact that was fine. Worse than the traceback
it replaced, because a traceback at least does not claim to know.
The verdict parse now raises AdjudicationError, which is what "this
command failed" already means in this file and already returns 2. Exit
code unchanged either way, nothing written either way; only the message
changes.
Suite 1073 -> 1074 passed (pytest exit 0, measured without a pipe);
ruff and mypy --strict clean.

A SegmentationError raised by the plan grammar escaped main() as a
traceback and exit 1, while every other malformed-plan case in the same
file already returned 2. Exit codes are the interface a caller scripts
against, and exit 1 with a traceback is the code an unhandled bug
produces -- it says "this command broke" where the truth is "this file
is not a plan".
The refusal itself is unchanged: nothing was written before and nothing
is written now, and the grammar in src/ is untouched. What changes is
one line on stderr naming the error code, and the exit code.
Both branches that can raise are covered: the pre-write parse of a
non-empty plan, and the required-field check reached through the empty
branch.
The old behaviour was pinned by
test_an_entries_value_that_is_not_a_list_is_still_refused, which
asserted that a wrongly-typed `entries` reaches the caller as a raised
SegmentationError and recorded that as a finding rather than fixing it.
That test is rewritten here, in the same commit as the code, to assert
exit 2 plus the code on stderr. A second test pins the one-line stderr
shape on the non-empty branch.
Suite 1072 -> 1073 passed; ruff and mypy --strict clean.

Measured on the K3 corpus: 4 of 12 judgements produced no artifact, because
the verdict was "none of these segments should be persisted" and the plan
grammar refuses zero entries. That refusal is correct for the run path -- an
empty plan replayed would silently persist nothing for a document that was
dropped -- so the grammar is untouched and the recording tool is taught to
record a rejection instead.
Refusing to materialize and refusing to record are different acts. The
rejection artifact is deliberately NOT replayable: parse_segmentation_plan
still refuses it, and the suite asserts that rather than assuming it. The dwell
time rides at the top level because there is no entry to carry it, and a
ratified rejection with no time on it is as unfalsifiable as a ratified
acceptance with none.
Only the empty LIST takes the branch. A missing entries key, or one that is not
a list, stays the grammar's to refuse: "the adjudicator kept nothing" and
"this file is not a plan" must not collapse.
K4a re-run after the change: propose, adjudicate, run the path twice into two
bundles under SEGMENTED_OKF_V0_2, diff -r exit 0 with no output. 1034 -> 1041
tests.
