dtourolle 0682d05f95 Let the tone curve continue past 1.0, and test that nothing clips
The tone curve clamped its input to [0, 1] and its output back to 1.0
around a 2.2 gamma, mid-chain — master and per-channel both. So any
edit with a curve made every scene value above 1.0 the same number
before the view transform ever saw it: D19's fourth finding. Beyond its
last point the curve now continues along its last span, whose secant
is the tangent the spline already gives that point, so the join is
smooth and an identity curve stays the identity to any height. The only
clamp left is the floor at zero, where there is no light to curve.

FR-DEV-2's acceptance test is how the rule stays true.
`scene_referred_until_the_view` wraps every point operation, at
non-neutral settings, between a gain of sixteen and one of a
sixty-fourth, with an identity in the view transform's place, and
renders a ramp from 0.4 to 15.2 times sensor saturation through it. The
output must still increase with the input and still separate the top of
the ramp. Run against the previous commit's tone curve it fails with
[21, 29, 33, 33, 33, 33, 33, 33]; every other operation already passed.
It renders on a device because dr-pipeline has none, and the spec's
pointer to it says so.

dtourolleandClaude Opus 5 0c3b8cb1c4 Hand out descriptors a declaration could produce
`Operation::descriptor()` returned `&'static OpDescriptor`, and that lifetime
is the whole reason a build-time node is free and a run-time node is
impossible: only a compile-time literal can satisfy it, so no amount of
reading `ops/*.yaml` at startup could ever produce a descriptor the rest of
the application would accept. FR-PLG-2 says a bundled operation and a
third-party plugin are the same kind of thing, differing only in where the
file was found — and a lifetime outsiders cannot meet is exactly the second,
weaker format that requirement forbids.

So a descriptor is now owned and handed out as `Arc<OpDescriptor>`, with `Vec`
where it held `&'static` slices. `Arc` rather than a `&self`-borrowed
reference because the callers want to *keep* it: the develop panel collects
descriptors and then mutates the graph, and a borrow would tie the
descriptor's lifetime to a borrow of the operation it came from, which is the
one thing `&'static` was doing right.

The identifier newtypes deliberately did not follow. `ParamId` is `Copy`, is
compared in `match` arms against generated constants, is a map key in the
sidecar and history, and reaches Slint model rows; an `Arc<str>` there would
cost a refcount on every one of those and would take `match id { EXPOSURE =>
.. }` away from the generated code. They gain an interner instead, which is
honest about its lifetime rather than pretending to one — the set of ids is
bounded by deduplication and is process-lifetime by construction, because the
sidecar on disk names its parameters and an id has to stay resolvable for as
long as any edit naming it can be opened.

No behaviour changes. Every descriptor that was a `static` is a `LazyLock`
initialiser now, `Operation::helpers` borrows from `self` instead of being
`'static` so a future run-time node can own its list, and `Warp` and `Framing`
follow `Operation` so there is one shape rather than two.

The one place a descriptor is read per frame is `compose_full`, which takes
`descriptor().id` to prefix each active operation's uniforms, and `dr-ui`
composes on every frame it draws. That is a dozen atomic increments beside a
composition that is already building several kilobytes of WGSL on the same
call; it is noted at the trait method rather than left for a profiler to find.

dtourolleandClaude Opus 5 c75849040c Format the tree the way the gate asks for it
`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.

dtourolleandClaude Opus 5 d64a61d677 Give the tone curve a curve for each colour channel
The declaration in ops/tone_curve.yaml has claimed per-channel curves since
it was written — it is the justification for the operation carrying both
`tone` and `colour`. Only the master curve existed. This is the other three.

The master runs first and the channels grade its result. Both orders are
real images and they differ visibly, so the choice is made and written down
rather than left to the loop: a point placed on the blue curve should act on
the tone the photographer can see, which is what the master has already
produced. The other order anchors the grade to tones the master is about to
move, so adjusting contrast slides a warm shadow up into the midtones.

Every id that existed before today is spelled exactly as it was. The master
curve keeps `p2_y` and the new curves take `r_`, `g_` and `b_` prefixes, so
a sidecar written when there was one curve loads, means what it meant, and
renders the same shader — asserted on the generated source, not on the
parameter values. Nothing needed a version check because nothing was
renamed.

Each curve reaches the shader only when it has been moved off the diagonal,
so an S-curve and no colour work generates what it generated when this
operation held ten parameters instead of forty, down to the uniform names.
The monotonicity guarantee is enforced per curve: a coincident pair on blue
divides by zero exactly as thoroughly as one on the master.

dtourolle 7421837c8a Let an operation say what it is about, so the panel can group without naming
Tool tabs need a taxonomy, and the taxonomy was the problem: a table in
`ui/` mapping operation to tab breaks FR-DEV-3a, and a `group:` field risks
what `ui-refinement.md` condemned `starts-group` for — the core deciding
where the panel draws things.

`Attribute` threads the needle. It says what an operation *is* — tone,
colour, detail, optics, geometry, effect — which is the same category as
`ParamKind` and squarely on the core's side of ARCH §4.3a's line. What is
drawn, where it sits and whether it is visible stay the frontend's. There is
no attribute for "the third tab", the enum's order is declaration order
rather than screen order, and a frontend may render these as tabs, as
headings, or ignore them.

The payoff is that a tab strip can be *derived*: the groups are the
attributes present in the capability list, so the interface names no
operation and needs no table to keep in step. An operation joins the right
group by declaring what it is, which is the one thing its author is well
placed to say.

Plural, because the tone curve is genuinely both — an RGB curve is tonal and
the per-channel curves are chromatic, and filing it under one would hide it
from half the people looking for it.

Required and non-empty, enforced in `build.rs`, and the failure was checked
by removing the line rather than assumed. An operation with no attribute is
invisible to a panel that groups by them; a build that stops costs ten
seconds, a control nobody can find costs more. The vocabulary is closed for
the same reason: a typo would otherwise invent a category holding exactly one
operation, which looks like a deliberate one until somebody counts.

Six tests over the real chain, including the hand-written operations that
`build.rs` never sees and so cannot check.

dtourolleandClaude Opus 5 0a331c717e Give the controls a vocabulary, and let a node ask for one
widgets.slint set the rule — screens consume components, and a bare `Theme.*`
at a call site means a component is missing — and it set it for chrome only.
The controls never got the same treatment, so they were written wherever they
were first needed and copied from there.

**The slider was private to the develop panel.** `SliderTrack`, with the
fifty-line preamble explaining how it wrests a drag away from a Flickable,
lived inside adjust.slint and no other screen could reach it. It shows: export
quality is a 1-to-100 value, and the settings page offered a free-text box for
it, with the range written in a hint and enforced nowhere. `to-float()` answers
0 for anything it cannot parse, so a typo saved a quality of 0 and the page
displayed the 0 back as though it had been asked for.

The tick-box was written twice, in launch.slint and settings.slint, from the
same 18px box and the same handler; the second carried a comment deferring the
lift until a third caller appeared. The label-and-hint header was written three
times inside settings.slint alone.

controls.slint is the input layer beside widgets.slint's chrome layer, and the
constraint that makes it reusable is that **nothing in it knows about
`ParamRow`** — that struct is the develop panel's flattening of the capability
model, and a control that imported it could only ever be used by the develop
panel. The primitives take plain numbers; the ParamRow-shaped wrappers stay in
the panel that owns the model. 658 lines came out of the three screens.

`SliderRow` is the slider-plus-number-box ARCH §4.3 names as the pointer
presentation of a bounded scalar, and quality is its first adopter. It commits
on gesture end rather than on every movement, because the settings page saves
to disk on change and a two-second drag is a couple of hundred writes where a
text field committed once. The develop panel keeps the live stream — that is
what its pipeline is for — so `SliderTrack` now reports both.

**The other half is the descriptor.** FR-DEV-3a and ARCH §4.3a already specify
more than was built: an ordered preference list of widgets rather than one, the
demands a widget makes, and kinds beyond scalar and bool.

- `Presentation.widgets` is now a list, walked by `choose`, falling back to
  plain sliders. Falling off the end is not an error, and there is a test
  asserting an operation asking only for an unimplemented widget still yields
  one control per parameter.
- `WidgetDemand` carries what a widget inherently needs — two-dimensional
  dragging, precise pointing — and no pixels, breakpoints or platform names.
- `WidgetKind` grows to the specified set. There is deliberately no `Colour`
  *kind*: a colour is three numbers, and a value type that is not an `f32`
  would reach through the graph, the uniform block and the sidecar format to
  buy what `ColourWheel` over three scalars already describes. Every widget
  here is a hint over ordinary scalars, which is what keeps the fallback
  honest.
- `ParamKind::Enum` is the one new shape, and it fits because a variant index
  is exact in binary32. `kind: enum` with a `variants:` list works in
  `ops/*.yaml`, so a node declaring one gets a segmented control with no UI
  file edited — which is the promise ops/mod.rs already makes.

The panel's dispatch was duplicated: a lone parameter and a grouped one each
wrote out their own list of kinds, so `enum` would have had to be added twice
and a kind added to one would appear or vanish depending on how many parameters
its operation happened to declare. `ParamControl` is now the only such chain.

`rows_from` is free-standing rather than a method, which is what lets the
FR-DEV-3c acceptance test requirements.md asks for actually be written: an
operation the frontend has never heard of, appearing in a generated panel, with
no GPU in sight.

dtourolle 2ca1716a29 Make "Choose folder" an actual folder picker
It previously fetched the folder list and threw it away into a status
line — a button that looked like it worked and did not. Now it opens a
browsable picker: click a folder to descend, ".." to go back, "Use this
folder" to select, "Cancel" to leave the root unchanged.

Descends one level per click because that is what the backend supports:
Depth: infinity is frequently disabled server-side and prohibitively
expensive where it is not (ARCH §8.4).

The chosen root persists immediately on confirm, so it survives a crash
before the library is opened. Confirming at the account root is allowed —
a user may legitimately keep everything at the top level — and cancelling
leaves any previous selection untouched, which a test asserts.

Verified against nextcloud.tourolle.paris at both depths: 30 folders at
the root, 21 year-folders inside PhotosRaw.

19 launch tests, 38 in dr-ui.

dtourolle f630a3ff81 Wire the launch screen into the app
The app now opens on the login screen when there is nothing else to show
— no local paths and no configured library — and goes straight to the
images otherwise. Making someone click past a login they already
completed is pure friction.

  launch.slint       imported by app.slint, replacing the window rather
                     than overlaying it: there is no library to look at
                     until an account is configured
  launch_ui.rs       the Slint wiring, kept out of lib.rs so the launch
                     flow can change without touching the develop window

Login runs on a worker thread and posts results back through a channel,
since Slint's event loop is single-threaded and a 20-minute browser wait
cannot block it. The system browser is opened via xdg-open, never an
embedded webview (FR-NC-1).

Sign-out deletes the local credential even if server-side revocation
fails: a network error must not leave a usable secret on the machine.
Format tick-boxes persist on each toggle, so a selection survives a
crash before the library is opened.

Two things deliberately incomplete rather than faked:

  - "Choose folder" lists the account's folders and reports them, but
    there is no picker widget yet, so selection still happens via the
    connect example.
  - "Open library" logs the request. Opening a remote library needs the
    scan-and-cache path, which belongs with the catalog work in flight.

Earlier I broke the other in-flight dr-ui work by calling
slint_build::compile twice, which replaces the generated module. The
correct wiring is an import inside app.slint, which is what this does.

30 dr-ui tests passing; both launch paths verified by running the app.
