+change. This is the part the existing design makes cheap.
+
+Slint turned out *not* to report window moves — there is no `on_moved` on any backend — so the
+window's position and scale factor are sampled twice a second and the platform re-surveyed only when
+they differ. See §5.4 for the display server where the position itself is unavailable.
 
 **5.3 Fractional scaling.** "Handled without resampling artefacts in the canvas" — the canvas is a
 wgpu texture handed to the compositor, so the requirement is that we render at the *physical* pixel
 size rather than the logical one and let the compositor present 1:1. Worth an explicit test, since
 the failure is subtle: a slightly soft canvas that looks like a bad demosaic.
 
+### 5.4 What landed, and the one thing that did not
+
+`dr_plat::display` surveys the session's displays; `dr_ui::display_ui` decides which one is showing
+the canvas and keeps `DevelopSession`'s output space pointed at it. Composition was already
+parameterised on the space, so the pixel path changed by one argument.
+
+Two things are worth recording because they are trades rather than omissions.
+
+**A profile is matched to the nearest of four spaces, not applied.** A measured panel is none of
+`Srgb`, `DisplayP3`, `AdobeRgb` or `ProPhoto`, and a general ICC engine is a much larger piece of
+work — a CMM, rendering intents, LUT-based profiles, and a per-frame cost to argue about. The
+profile is reduced to its D50-adapted colorants and matched against the four; a match that is merely
+nearest is marked as such, and About says "nearest to Display P3" rather than "Display P3". A
+LUT-based profile, which is what a hardware calibrator often writes, is declined by shape and falls
+back to sRGB with that stated. An approximation the photographer can see beats a silent one.
+
+**On Wayland the canvas follows the first output, not the window.** A Wayland client is never told
+where its window is — `xdg_toplevel` carries no position, deliberately — so the "which display"
+question cannot be answered by geometry there. The protocol's own answer is
+`wp_color_management_surface_feedback_v1`, which hands a client the preferred image description for
+*its surface* and re-sends it on a move; it needs the application's `wl_surface`, which Slint owns
+and does not expose. So the profiles are read correctly for every output and the *selection* among
+them is right on X11 and on any single-monitor Wayland session, which is most of them. Closing the
+gap is a Slint surface handle, not a change to any of this.

+//! TRACES: FR-DSP-8 | FR-PLAT-LIN-2 | NFR-PORT-1
+//! What colour the screen in front of the photographer actually is.
+//!
+//! The display path is colour-managed by encoding the render into the output
+//! device's space (FR-DSP-6); that space is a parameter of composition, so
+//! getting it right is a question of *asking the platform* rather than of
+//! doing anything to the pipeline. This module is the asking.
+//!
+//! # Why this is a correctness problem and not a polish one
+//!
+//! FR-DSP-8 says so itself: "on a multi-monitor desktop with differing
+//! profiles, showing wrong colours on the second display is a correctness
+//! defect, not a polish item". Every other display requirement fails by being
+//! slow. This one fails by being *quietly wrong* — a photographer grades a
+//! skin tone on a wide-gamut panel, the app encodes sRGB into it, and the
+//! result is oversaturated on screen and correct in the file, or the reverse.
+//! Nothing about the image looks broken. That is the whole danger.
+//!
+//! # Acquisition is stated per display server, because it differs entirely
+//!
+//! - **X11** publishes ICC profiles as root-window properties: `_ICC_PROFILE`
+//!   for the first output and `_ICC_PROFILE_<n>` for the rest, a convention
+//!   from the ICC Profiles in X specification that colord, xiccd and
+//!   `xcalib` all write to. The bytes are a whole ICC profile.
+//! - **Wayland** has no such back door — a client cannot read another
+//!   client's or the compositor's state — and the protocol that replaces it,
+//!   `wp_color_manager_v1`, is still *staging* upstream. Where the compositor
+//!   advertises it we ask it; where it does not, there is no mechanism at all
+//!   and we say so.
+//!
+//! FR-DSP-8 anticipates exactly that gap and demands "a defined fallback where
+//! Wayland provides no profile". The fallback is sRGB, and the requirement's
+//! wording — *defined*, not *silent* — is why [`ProfileSource`] carries the
+//! reason as data rather than logging it: the About page renders it, so a
+//! photographer being shown sRGB because the compositor would not say
+//! otherwise can find that out rather than wonder.
+//!
+//! # Four spaces, and no ICC engine
+//!
+//! The pipeline can encode into four spaces ([`ColourSpace`]). A real display
+//! profile is a measurement of one panel and is none of them. Rather than
+//! grow a general ICC transform engine — a much larger piece of work, with a
+//! CMM, rendering intents, LUT-based profiles and a per-frame cost to argue
+//! about — this reduces the profile to its primaries and picks the nearest of
+//! the four, and then *says that it did*. See [`nearest_space`].
+//!
+//! An approximation the photographer can see beats an exact answer they
+//! cannot, and beats a silent approximation by a much larger margin.

+//! TRACES: FR-DSP-8
+//! Reading just enough of an ICC profile to say which of four spaces it is.
+//!
+//! # Deliberately not a profile parser
+//!
+//! ICC.1 is a large specification, and a complete reader of it is the front
+//! half of a colour management module: LUT-based transforms, rendering
+//! intents, per-intent tag sets, v2 and v4 divergence. None of that helps
+//! here, because the pipeline does not *apply* a profile — it encodes into one
+//! of four spaces it already knows the numbers for (`dr_types::colour`). The
+//! only question a display profile has to answer is which of the four it is
+//! nearest to, and three tags answer it.
+//!
+//! So this reads the tag table, pulls the three colorants and the description,
+//! and refuses everything else with a reason the About page can show. A
+//! profile it refuses is not a failure of the photographer's setup and must
+//! not read like one; it means "this panel is described in a way we do not
+//! approximate", and sRGB is assumed as FR-DSP-8 defines.
+//!
+//! # What it does read
+//!
+//! `rXYZ`, `gXYZ`, `bXYZ` — the three colorant tags of a matrix/TRC profile,
+//! which are the space's primaries already adapted to the D50 connection
+//! space. That is the same reduction `ColourSpace::to_pcs_xyz` produces, which
+//! is what makes the comparison in [`super::nearest_by_colorants`] an
+//! apples-to-apples one, and what makes a profile this project *wrote*
+//! round-trip back to the space it was written from.
+//!
+//! `desc` (v2) or `mluc` (v4) for the profile's own name, which exists only to
+//! be shown: a photographer recognises the string their calibrator wrote and
+//! can tell at a glance whether we are reading the profile they think we are.

+//! TRACES: FR-DSP-8 | FR-PLAT-LIN-2
+//! Acquisition on Wayland: ask the compositor, or admit that we cannot.
+//!
+//! # Why there is no back door here
+//!
+//! X11's mechanism works because any client may read any root-window
+//! property. Wayland has no such shared state by design — a client sees its
+//! own surfaces and nothing else — so the profile has to be *given* to us, and
+//! the protocol that gives it, `wp_color_manager_v1`, is still staging
+//! upstream. That is the concrete form of FR-DSP-8's "a defined fallback where
+//! Wayland provides no profile": on a compositor that does not advertise the
+//! global there is no mechanism to fall back *from*, and pretending otherwise
+//! would mean reading the Xwayland root window and presenting a value the
+//! compositor never agreed to.
+//!
+//! So: bind the global if it is there, ask each `wl_output` for its image
+//! description, and where it is not there return
+//! [`FallbackReason::NoWaylandProtocol`], which the About page renders in
+//! words.
+//!
+//! # Two forms of the same answer
+//!
+//! The compositor may describe an output either by handing over an ICC profile
+//! on a file descriptor or by stating primaries as CIE xy chromaticities.
+//! Both are accepted, and both reduce to the same nearest-space decision — see
+//! `super::nearest_by_colorants` for why that reduction has to happen in one
+//! place. The ICC form is preferred where both arrive, because it carries the
+//! profile's own name, which is the string a photographer recognises.
+//!
+//! # Position is deliberately not asked for
+//!
+//! [`super::DisplaySurvey::containing`] explains the consequence at length:
+//! `bounds` is `None` on every Wayland output, not because `wl_output` refuses
+//! to state its position but because a client is never told where its *own*
+//! window is, so a rectangle to test against would have no point to test.

+//! Acquisition on X11: ICC profiles as root-window properties.
+//!
+//! The mechanism is the ICC Profiles in X specification, and it predates
+//! everything else in this module by two decades. A colour manager — colord
+//! under GNOME, `xiccd`, `xcalib`, or the desktop's own — loads the profile
+//! for each output and publishes its bytes on the *root window* as a property:
+//! `_ICC_PROFILE` for the first output, `_ICC_PROFILE_1`, `_ICC_PROFILE_2` and
+//! so on for the rest, numbered by the output's position in RandR's list.
+//!
+//! Any client can read them, which is exactly why this works and exactly why
+//! [`super::icc::read_profile`] validates so carefully: a root-window property
+//! is untyped shared state that anything on the display may write.
+//!
+//! # Geometry comes from RandR, and it is what makes a move detectable
+//!
+//! X11 will also say where each output sits in the desktop's coordinate space,
+//! and will tell a client where its own window is. Those two facts together
+//! are the whole of FR-DSP-8's "updates when the window moves between
+//! displays" on this display server — the window's centre falls in one
+//! rectangle or another, and the answer changes as it is dragged. Wayland
+//! gives neither, which is why `wayland.rs` says what it says.

+//! Following the canvas from one display to the next.

+//! `dr_plat::display` establishes what each display *is*. This decides which
+//! of them is showing the canvas right now, keeps the develop session's output
+//! space pointed at it, and renders at that display's physical pixel size
+//! rather than its logical one.
+//!
+//! # Why a poll and not a callback
+//!
+//! Slint reports a window's size and its scale factor and does not report that
+//! it has moved — there is no `on_moved`, on any backend. What there is, is
+//! `Window::position()`, so this samples it. A sample is three integers
+//! compared against three integers and happens twice a second; a monitor is
+//! changed at human speed, and nothing here runs on the frame path.
+//!
+//! The re-survey is what costs something — a Wayland roundtrip pair, or an X11
+//! property fetch — so it is deliberately *not* done every tick. It runs when
+//! the geometry actually changed, which is also the moment a monitor could
+//! have been plugged in or unplugged: both of those move or rescale the window
+//! on every desktop that does anything sensible.
