A spot set now composes detail passes of its own, one per round, and they
go ahead of every operation's kernel. That placement is the decision worth
recording: a sharpening pass reads a neighbourhood, so sharpening a dust
mark before removing it smears its edge into pixels the repair's disc does
not cover, and what survives is a faint over-sharpened ring around an
otherwise perfect patch. It also disagrees with ARCH §5.2, which draws
spot removal after clarity — docs/spot-removal.md §5.1 is where that is
argued out.
Every length reaching the shader is in render pixels, converted here where
the framing is in scope. Both the centre and the source go through
`Framing::output_at` — the same map the fused pass applies to every pixel
— so a rotated photograph rotates the offset with no trigonometry, and the
radius is found by mapping a point one radius above the centre and
measuring, rather than by multiplying by a ratio this function has no
business knowing about. The tests turn and crop the frame and expect the
mark to stay gone, which is the property that arrangement buys.
compose_full now takes the spot set, because a photograph with a repair
and no sharpening still has a detail stage: a fused pass that encoded its
own output there would quantise twice and bind to a texture of the wrong
format. compose_detail_for takes the source size for the same kind of
reason — a RenderScale describes the region on screen, and a spot is
stored against the photograph.

CI runs cargo fmt --check and clippy -D warnings, and this branch had
never been through either. Both would have failed it.
The bulk was the generated colour tables: eight significant figures where
an f32 carries about 7.2, so the eighth is noise that rounds away at
compile time and clippy's excessive_precision says so 109 times over.
Fixed in the generator rather than only in the file, so it stays fixed --
and the file is trimmed in place rather than re-derived, because
regenerating it needs a colour-science stack that has nothing to do with
the defect.
The format! in the composer is mine too, from extracting the rendering
tail: the braces in it were escaped because the text used to live inside a
larger template, and once extracted the escapes are noise and the call
formats nothing.
Also here, and clearly not mine: an unused import and a shadowed binding
in dr-gpu, and an unused import in a test. They are pre-existing --
clippy has been failing on master before this branch existed, on lints
like is_multiple_of that arrived with a toolchain rather than with
anyone's code. Fixed because CI cannot go green around them, and called
out because a merge commit is a bad place to quietly edit someone else's
crate.

`cargo fmt --check` is a required step and had drifted across 45 files. Most of
it arrived this week: several operations were written in parallel worktrees and
merged by hand, and a hand-merge resolves conflicts without ever running the
formatter over the result.
No behaviour changes — this is `cargo fmt --all` and nothing else, kept as its
own commit so the next reader can skip it wholesale rather than search it for
one that matters.

`texture_contributes_nothing_where_its_scale_does_not_exist` asserted that the
detail chain composed *nothing* when texture's kernel rounded away, and its
comment recorded that empty chain as a gap: the fused pass had already decided
to hand on linear working values, so an empty chain left the output transform
undone and the render was rejected. It said fixing it meant composing both
halves together, at the composition boundary rather than in that file.
Noise reduction closed it there in the same round, by emitting a bodyless
`detail/resolve` pass for exactly this case. So the assertion was describing a
defect that no longer exists, and failing because the defect was fixed.
Now asserts the property it was always about — texture contributes no kernel,
`radius() == 0` — while the chain carries the one pass that finishes the
render. Two agents working in parallel each saw one half of this; it is only
visible with both merged.
A test that cannot be run cannot be checked by running it, and a number
copied out of a test run agrees with whatever the code did on the day.
Each asserted kernel width, tolerance and overshoot bound now carries the
arithmetic that produces it -- the shorter edge, the sigma, the
truncation at two sigmas, and where the rounding falls -- so a reader can
verify the expectation against the recipe without a GPU or a compiler.
Also records the two places where a bound is a bound and not a
measurement: the tolerance in the frame-fraction test is exactly what
rounding a kernel to a whole pixel costs on the smallest frame it uses,
and the halo test's floor and ceiling bracket a peak derived from the
step, the soft limit and the midtone taper rather than from a run.

`the_whole_chain_at_once_compiles` counted one `---- ` block per
operation in the chain. That was true while every operation was a point
operation, and stopped being true the moment a neighbourhood one existed:
clarity and texture are active in that test, and still emit no fused
block, because `compose_full` filters them out and the detail stage
dispatches them separately.
Counted now by asking each operation whether it has a detail stage --
the same question the composer's own filter asks -- rather than by
subtracting a number someone has to remember to update. Capture
sharpening and noise reduction are covered by this without another edit.
The render at the end is now `render_detailed`, which is not a
concession but the stronger test: with a neighbourhood operation active
the fused pass hands on linear working values and the last detail pass
performs the output transform, so rendering the fused half alone is the
mismatch `render_detailed` exists to reject -- and the detail passes are
generated WGSL with uniform blocks of their own, which is exactly what
"everything at once" is here to collide. It renders at 512 rather than
32 because a compositional radius is a fraction of the frame, and on a
32-pixel target every detail kernel rounds away to nothing.
Also records, in `texture_contributes_nothing_where_its_scale_does_not_exist`,
the seam this uncovered: an active detail operation whose kernel rounds
away composes an empty chain while the fused pass has already been
composed to hand on linear values, and nothing can then encode the
result. That test now asserts the property on the composed chain instead
of driving the unrenderable configuration.

Checkpoint committed by the coordinator, not by the authoring agent: the
session hit its API limit mid-task and left this work uncommitted. Committed
so it survives, NOT because it is finished - expect failing tests and
half-applied changes. The agent resumes from here.
