`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.

Four decisions: Door C projects and never derives (D-C1), the projection is
key-agnostic so it is not about numbering (D-C2), an unrenderable value drops
the facet and never the concept (D-C3), and a faceted entry is refreshed
because it is the first entry that can go stale (D-C4).
Also records a measurement about the measuring. The mutation harness first
reported 11 of 11 killed; the number was entirely false, because it invoked
pytest with an unrecognised `--timeout` flag and every run exited non-zero. The
negative control caught it by being reported killed when it provably could not
be. Honest result is 9 of 11, with both survivors analysed as equivalent
mutants and the one real gap they exposed (profile threading pinned only by
coincidence) closed with a direct test.
Closes open item 6 of the Door B record, which asked exactly the question this
answers: whose claim does the frontmatter make.
vegnormal-okf measured the gap on 2026-08-27: the arm reading DEFAULT's
index.md scored 0 hits of 8, the arm reading a faceted index of the same
frontmatter scored 25 of 29. Same bundle, same concepts, same model. The
DEFAULT arm did not answer wrongly, it abstained -- the metadata is in the
bundle and the index throws it away (30 974 characters over 269
requirements, 0 occurrences of any of the eight facts).
FacetPolicy and STRUCTURED_V1 already did this. They did not reach Door C.
`import_bundle` now takes a keyword-only `profile` defaulting to DEFAULT, so
every existing call site emits the bytes it always did, and `link_in_index`
takes the facets to render.
Door C PROJECTS and never DERIVES, which is the answer to the objection this
work opened with: deriving structure for a document a third party wrote would
put our inference into an index entry ABOUT their bytes, where it reads as
their claim. The concept file was already verbatim; the entry describing it
now is too. Where the sender carries `derived`, THEIR list travels unchanged,
so a reader can still see which of the sender's facts the sender inferred.
The projection asks the policy which keys to carry and never what a key
means. That is what makes it work for a meeting note as well as a numbered
norm -- nothing in it can key off a numbering scheme -- and it is why a
consumer whose concepts are named by UUID can get `title` into the index by
naming the key, with no change here.
Two things measured during the work rather than assumed:
- A value carrying the policy's own joiner cannot be rendered. Door C's
tolerance is structural and it refuses no sender on form, so the FACET is
dropped and the concept still merges -- reported per concept and key in
`ImportResult.unrendered_facets`, never dropped silently.
- A faceted entry can go stale where a flat one never could: the collision
gate refuses an updated concept, so the operator's only route is to remove
the merged file and re-import, after which the file said `gjeldende` while
the index still said `utkast`. A faceted entry for a present target is now
refreshed in place instead of skipped. Unfaceted callers keep the early
return byte for byte.
Suite 695 -> 707; ruff and mypy --strict clean.
Order 20260826T224500Z-873805419-from-vegnormal-okf.
