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.

Nothing here is film simulation. These are lints that fail master today,
under the -D warnings CI runs with, mostly from a toolchain that learned
new ones rather than from anybody's code -- `is_multiple_of` and the
derivable `Default` did not exist as lints when this was written.
They are fixed rather than allowed, and by hand rather than by trusting
`cargo clippy --fix` wholesale: its automatic pass split a derive in two
and left a stray blank line, which is the sort of thing that is correct
and still wrong to commit.
The four that needed a decision rather than a rewrite:
- The distance transform's inner loop writes through its iterator now.
`q` stays, because it is the position the parabola is evaluated at as
well as the index it is written to -- the lint is about the write.
- `to_source` and `to_proto` take `self` by value. Their receiver is
`Copy`, so this is the same machine code and the honest signature.
- The export path's return type is five levels deep and now has a name,
plus a line saying why the `Option` wraps the `Result`: `None` is
cancellation, which is not a failure and has no error to report.
- A test fills a range instead of looping over one.

`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.

Capture sharpening as a two-pass unsharp mask in the detail stage: blur
along x, then along y, each pass applying a one-dimensional high-pass to
luminance so the composite preserves a flat field exactly and matches the
textbook kernel on any locally one-dimensional edge.
The radius is stated in source pixels and converted once per render, so a
radius tuned on a fit view is the radius the exported file gets. Below one
render pixel the operation declines to draw rather than showing sharpening
the file will not contain, and emits a single pass-through that still
carries the output transform.
The develop session now renders through render_detailed, which is what
lets an active neighbourhood operation reach the screen at all.

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.
