dtourolleandClaude Opus 5 c4ddcbe0f7 Look the lens up and say plainly whether one was found
`dr-lens` has held a complete Lensfun lookup — distortion, TCA and vignetting
coefficients from a lens name, a focal length and an aperture — with no
dependents anywhere in the workspace. The three corrections it feeds now
exist in the graph, so this connects the two and finishes the chain.

The coefficient structs stay duplicated. `dr-pipeline` is organised around
having no dependencies so its codegen is testable without a device or a
database (ARCH §6.5a), and `dr-lens` carries an XML parser and 5.5 MB of
profile data. Neither crate can convert to the other, so the conversion goes
above both, in `develop.rs`, which is the only place that sees them together.

Both traits grow the same defaulted door. The optical corrections do not sit
on the same side of the fetch — distortion and CA rewrite coordinates and are
`Warp`s, vignetting applies a gain to the pixel already there and is an
ordinary node — and fanning a profile out by which trait each happens to
implement would make the caller reason about that distinction. Each correction
takes its own share of the whole profile instead, and `set_lens_profile` walks
both lists identically.

The lookup happens in `set_source_metadata` rather than in its caller, because
that is the one place a session is told which file it came from. Doing it
there makes it unforgettable, in the shape `FilmRebake` already uses for the
other derived thing — and, more to the point, makes *clearing* unforgettable:
a session that opened a second photograph while still holding the first one's
profile would correct it for the wrong optics, invisibly, in a way that looks
exactly like the lens.

It needs the whole shot and not just a name. Distortion is interpolated across
a zoom's focal range and vignetting depends strongly on aperture — a fast
prime can be two stops down in the corners wide open and clean by f/8 — so a
lookup missing either returns coefficients measured for a shot nobody took.
Missing any of the three refuses rather than guesses.

A profile is derived, not persisted: it comes from the file's EXIF and a
database, so it is not a parameter, not in the sidecar and not undoable. What
is an edit is the manual trim beside it, which each correction composes with
the measurement — so a photographer can lean on it, override it, or work
without one.

`InfoPanel` gains a lens line, and it distinguishes three cases rather than
two. `dr-lens` states the rule it exists for: an automatic correction that
silently did nothing is worse than one the user can see is unavailable. A
session with no header draws nothing, a header naming no lens reads "Lens not
recorded", and a lens the database has never heard of reads "· no profile".
Collapsing the last two would send somebody hunting for a profile that was
never missing — which, for third-party and adapted glass, is the ordinary case.

# The renderer is shared, but the backend is not: winit on desktop,
# android-activity on Android, and enabling both makes the backend selector
# pick at random. So the backend features live on the target-specific
# dependencies below rather than here.
#
# `renderer-femtovg-wgpu` rather than `renderer-femtovg`: the latter is
# FemtoVG over OpenGL, and a compositor drawing through GL cannot be handed a
# `wgpu::Texture`. Importing one requires Slint itself to be rendering with
# wgpu, and this is the FemtoVG backend that does (ARCH §6.1, spike S1).
#
# `unstable-wgpu-29` is the other half: the renderer feature makes Slint draw
# with wgpu, and this one exposes the API to say so — `BackendSelector::
# require_wgpu_29` and `Image::try_from(wgpu::Texture)`. Unstable is Slint's
# word for it; the surface is small and the alternative is the 7 ms round-trip.
#
# `renderer-femtovg` is *not* kept alongside as a fallback, though it would
# still compile. Slint's winit backend prefers the wgpu FemtoVG renderer
# whenever both are built, so the GL one would only ever be reached by someone
# setting `SLINT_BACKEND=winit-femtovg` — and on that path an imported texture
# is not drawn at all. FemtoVG-over-GL has no branch for a `wgpu::Texture`, so
# it falls through to "render this image to a buffer", gets nothing back, and
# draws nothing. A blank canvas with no error is a far worse failure than the
# one below, so the fallback is removed rather than left as a trap.
#
# Consequence worth stating plainly: the desktop app now needs a working wgpu
# adapter to open a window at all. Slint refuses a CPU adapter for this
# renderer unless `SLINT_WGPU_CPU` is set in the environment.
# TEST BUILD: the wgpu renderer features have moved to the desktop-only
# dependency below. On Android they made `AndroidWindowAdapter` choose
# `SkiaRenderer::default_wgpu_29`, and so put the app on wgpu's Vulkan
# swapchain — which hardcodes `preTransform = IDENTITY` (gfx-rs/wgpu#3345).
# Without them the Android backend uses `SkiaRenderer::default`, which on
# Android resolves to Skia over OpenGL, where the driver owns the display
# rotation and there is no transform to get wrong.
