dtourolleandClaude Opus 5 baa8957e80 Let a photographer choose the film, and remember which one
The stock model rendered correctly and nothing could ask for it. This is
the picker, and the sidecar key that makes the choice outlive the session.

How the choice persists was the open question, and the answer was already
written down twice in sidecar.rs: `rating` is a top-level key "because a
rating is not an edit", and `masks` are one "because a layer is not a
scalar". A stock is that kind of thing -- a choice of material, not a
number a slider moves -- so it is a top-level key too.

It stores the **id**, not an index. Stocks are files that users add, so an
index would mean installing a profile silently changed which film every
existing photograph had been developed on. A name this build has no
profile for still round-trips untouched, because the alternative is that
syncing to an older phone quietly un-develops the picture.

Only the names travel. Turning one back into tables needs the profile
database, which dr-pipeline deliberately does not link, so `Version::apply`
clears the film and the session re-bakes -- after the parameters, because
the bake reads the film's own exposure sliders and the print balance is
solved against them. That is also why moving those sliders rebuilds the
lookup where no other control in the panel does: an enlarger's filtration
depends on how the negative was exposed.

The panel keeps its rule. It still names no operation and still generates
every control from a declared parameter kind; the stock gets a bespoke
control beside those, exactly as the mask stack does, and for the same
reason. The film's exposure and print exposure arrive as ordinary
generated sliders.

Two defaults worth stating. Picking a colour negative prints it, because
an unprinted one is an orange strip and offering that as the first thing
somebody sees after choosing Portra reads as a bug rather than as a
choice -- the toggle is there for anyone who wants the scan. And a paste
carries no film: a preset is a parameter map, and a stock is not a
parameter, so pasting one would paste a choice the clipboard never took.

dtourolleandClaude Opus 5 7c8e433911 Load the window around the whole view, not around its first cell
The bottom row of the grid was often blank, at a scroll position the user
could sit at indefinitely. Two numbers decided when the loaded window follows
the view, they lived in different languages, and they disagreed.

The grid loaded three screenfuls and Rust held the window still until the
first visible cell was three quarters of the way through them. Three quarters
of three screenfuls is 2.25, and the view itself is one screenful tall — so
the bottom of the screen had already travelled a quarter of a screenful past
the last loaded cell before anything moved. Those rows are not in the model,
so nothing is drawn for them.

The same margin was wrong upward, and exactly so. The window is placed a
quarter of itself behind the view, and the margin then declared the view too
close to the top at precisely that distance: every single row scrolled upward
re-read the catalog, rebuilt all 360 cells and re-queried their badges and
ratings, and so did the row after it.

So the grid now reports what it shows — a screenful, counting the row the
scroll position has cut in half, which `visible-rows` alone undercounts and
which is exactly the row reported missing — and Rust owns the rest: four
screenfuls loaded, placed a quarter back, and moved once the view comes within
half a screenful of an edge of them. One decision in one place, and the test
now walks the view the length of the library and asserts the window covers it
at every step.

dtourolleandClaude Opus 5 fa4ad6e2d6 Drag the date range on the axis it is chosen from
The range could be turned on with a finger and not aimed with one. Its two
ends were typed as `YYYY-MM-DD` into 108px fields behind a soft keyboard, to
name days already drawn on the axis a thumb away; and the chip that seeds them
takes its span from the timeline's zoom and pan, which are a wheel and a middle
button. A touch screen has neither, so on Android the filter was a switch with
no aim.

The band is now on the timeline. Two ends with grips, dragged along the bars,
released to filter — the histogram was already how a period is found, and this
makes it how a period is stated. Both ends snap to whole days, which is what
the typed fields mean, what `show_range` reads back out, and a floor under a
range dragged shut. The fields stay for what dragging cannot do: name an exact
day, and say in words what the range is.

For that to work the axis had to stop following the range. Redrawn to the band,
it moved the ground under the very handles doing the narrowing, and there was
nothing outside the range left to widen back into.

While there: a fixed number of equal bins instead of calendar buckets. Between
one calendar unit and the next the bar count is free to wander by a factor of
twelve, so zooming in halved it two steps out of three — the same picture drawn
wider until it jumped back to fine. Equal bins also include the empty ones, so
a bar's position on the track and the date under it are finally the same
quantity; before, a library with gaps drew a February six months wide and the
marker, the band and a click all pointed somewhere else. The count is a
setting, 32 or 64, because the right answer is a question about the screen.

Three things a selection needed and did not have.

**Seeing it.** The count existed — "12 selected" — in the header row, which
scrolls sideways. On a tablet it sat past the right-hand edge along with every
button beside it, so a selection was something you could make and then not
see. A selection you cannot see is one you act on by accident.

**Putting it down.** The only way to clear one was "Done", which also leaves
select mode — so after filing forty photographs the next forty began by
re-entering a mode the user had not meant to leave. Clearing is now its own
action and keeps the mode.

**Filing it somewhere new.** Making a collection of a selection took four
steps: create one, find it in the tree, select the photographs again because
creating it changed the scope, then add them. It is one press, which is how a
selection is usually meant — it is gathered *because* it is going somewhere.

The new collection is created at the top level rather than inside the current
scope, unlike the tree's "+". A selection can be gathered from anywhere,
including across collections, so filing it under whichever one happens to be
open would put it somewhere its contents did not come from. It opens straight
into its name field, for the reason `collection_new` already does: the
placeholder name is nobody's choice, and making the user find the rename
afterwards is asking them to finish a job we started.

All of it on its own strip beside the date range's, appearing only while there
is a selection — the third control this session that was invisible for being
put in a row that scrolls.

dtourolleandClaude Sonnet 5 b3641b5307 Let a subject's mask be refined, and let several masks be edited at once
Two related gaps in the mask panel, from the same conversation: a subject's
outline is only ever as sharp as the whole-frame pass that found it, and a
change meant for several layers had to be dragged once per layer.

## Refine mask

A "Refine mask" button on a subject layer re-runs detection on a padded crop
around that instance's own box instead of the whole frame — the subject
reaches the model at its own size rather than squeezed into the model's fixed
640x640 window alongside everything else in the photograph. `RefineJob`
mirrors `SegmentationJob`'s split (built on the session, run off it, adopted
back), and the crop itself is rendered through `Framing::set_view` — the same
ephemeral viewport the interactive zoom already uses to render a region above
proxy resolution, so no new render path and no change to the model's own
input size was needed. `dr-segment` is untouched: `Tiling::Whole` already
treats whatever buffer it is handed as the one window.

The result is still downsampled onto the shared proxy grid every instance's
mask lives on, but from a sharper source than the whole-frame pass ever saw
for that subject, which is what the edge actually reads out of.

## Multi-select

`active_mask: Option<String>` is now `active_masks: Vec<String>`. A plain
click still replaces the selection; a control- or command-click toggles one
layer in or out of it. `set_param` and `reset_op` fan out to every selected
layer, each set to the exact value the slider now shows rather than offset by
however far it already was — one slider, one reading, applied everywhere
selected. Dragging a gradient's on-canvas handle is deliberately not
extended to multi-select: several gradients have no single geometry a shared
handle could move, so `gradient_handles` stays empty unless exactly one
layer is selected.

dtourolleandClaude Opus 5 4b7648082e Let a date range be stated, and draw the axis at the scale it deserves
"Limit to range" did nothing, and the reason was not visible from the button.
It took its span from the timeline's zoom, which is zero until someone zooms —
so `zoomed_span` returned the whole library and the filter narrowed to
everything. The chip lit up and the grid did not change.

The range has ends now, shown and typed as `YYYY-MM-DD`. Seeding them from the
timeline is kept, because zooming to a fortnight and pressing the chip is the
fast path; the fields say which fortnight it landed on and let it be corrected.
Ends given backwards are swapped rather than refused — there is exactly one
range between two days — and the closing day is included, since "to the 5th"
means the whole of the 5th and a range ending at its midnight contains none of
it. `parse_date` refuses anything that is not a date rather than guessing at an
order, because the alternative is a library silently filtered to a span nobody
asked for.

The axis then follows the range. It used to keep drawing the full extent while
a range was on, because it was the only way back out; the typed ends are the
way back out now, so it is free to show what was asked about.

And bucket size is chosen by how many bars it makes rather than by fixed
cut-offs. Each zoom step halves the span, so under thresholds the bar count
halved with it until a boundary was crossed: fifteen years went 15 bars, 8,
then 46, 23, 11, and finally 6. Zooming in made the picture coarser, which is
the opposite of what zooming is for. Aiming at forty bars keeps the count in
the same neighbourhood at every level, and the test asserts the property
directly — halving a span never coarsens the bucket.

dtourolleandClaude Opus 5 a8969c149e Move the instrumentation off the header and into About
The render backend, the layout class and the frame rate sat permanently in a
44px strip that also carries the only way out of develop, the undo pair, the
panel toggle and the export button. They cost about 200 logical pixels, and a
`HorizontalLayout` given less width than its children's minimums does not
shrink them — it runs off the end.

There was already a breakpoint hiding them below 820px, which is why a tablet
in portrait (768) looked fine and landscape (1200) did not: above the
breakpoint the readouts came back and pushed the header off the right-hand
edge. A breakpoint that hides a problem at one size and not another is a
workaround, and this removes the reason for it rather than moving it.

They are diagnostics — read once when something looks wrong, and then not
again — so they are in Settings under ABOUT, beside the version, which is
where someone goes when they have a bug to report rather than a photograph to
edit. The version is there for the same reason and comes from
`CARGO_PKG_VERSION`, so the line cannot disagree with the binary showing it.

The frame rate keeps its warning hue. It is the number that says whether the
zero-copy display path is holding up, which is the assumption the whole
display design rests on, and that is worth colour wherever it is shown.

dtourolleandClaude Opus 5 7fcb8dc107 Give the develop column room, and the mask a way out of the way
Three faults reported together, and they share a shape: each is something the
panel decided on the photographer's behalf.

**The column was 280px on every screen.** That width was chosen for a tablet,
where the column is a large fraction of the display and every pixel of it is
taken from the photograph. On a desktop window the mode strip alone — two
modes, a separator, "All", and a chip per attribute the operation set declares
— does not fit, so it scrolled sideways. A control you have to pan to reach is
one you do not know is there. 380px when the window is classed expanded, 280px
when it is not; driven off `layout-class` because reading the window width
inside the layout that sets it is a binding loop.

**The overlay could not be hidden.** An earlier "Overlay" button was removed
for a good reason — it *armed* the overlay, so local mode could be entered and
still show nothing. Hiding is the opposite need and was never served: a mask is
judged against the photograph beneath it, and that photograph is exactly what
the overlay covers. `overlay-hidden` is kept separate from `overlay-on` so a
recompute cannot switch the overlay back on under someone who just turned it
off.

**The masks were coarse because the model saw the subject small.** The graph's
input is a fixed 640x640 and every frame is letterboxed into it, so a bird
200px across in a 1600px proxy reaches the model at 80px. `Tiling::Grid` has
been implemented and tested since the segmentation spike and defaulted off,
because it costs one inference per tile — 2.8s for a 3x2 grid against 470ms.
Now offered as "Look closer (slower)", which says what it costs, rather than
spending it on every image or on none.

The tiling choice enters the segmentation signature. A mask stores the
signature its region ids index into, and a tiled run finds different instances
in a different order; sharing a signature would silently reinterpret a layer
built against the coarse pass — a wrong mask rather than a stale one, and
nothing announces it.

dtourolleandClaude Opus 5 d04087af83 Import into the library, which is on the server
There was a local destination, defaulting to ~/Pictures, and an "upload" switch
that could be turned off. That was wrong twice over. DarkRoom's library *is* a
folder on a Nextcloud server (FR-NC-6) — there is no local library — so a
user-chosen local destination built a second pile of photographs that no view
in the application ever lists, and made "where did my import go" a question
with two answers.

An import now has exactly one destination and the page asks nothing about it.
With no account there is nowhere to go at all, so Import is refused rather than
quietly filling a folder.

What lands on the device is a staging copy in a directory the app owns, the
same shape `export` uses for its outbox and for the reason its module docs
give: staging first is the only path, not a fallback for being offline. The
bytes have to reach disk before the network — streaming a card straight to the
server would let a move-import erase a card against an in-flight upload, and
would make importing impossible with no connection (FR-NC-10). A staged file is
removed once the server confirms it; one that is not confirmed stays queued, and
the next import drains it.

And the rule that was stated but never enforced: `retirable` was reported and
`dr_ingest::retire` was never called by anything, so a move-import silently
behaved as a copy. The card is now emptied by the worker, of exactly those
photographs the *server* has confirmed — not those merely written here, because
the staging copy is removed moments later and anything unconfirmed would then
exist nowhere at all.

FR-NC-7b said "copied locally first ... then queued for upload", which is a
staging area; it has been rewritten to say so in terms that do not also permit
what was built.

dtourolleandClaude Opus 5 28325af448 Make the thumbnails while the originals are still in hand
An import read every byte of every original, uploaded them, and then left the
grid to fetch a preview range back out of each one over the network — for
files that had been on this machine minutes earlier.

The pixels are now made from the bytes already in memory, on the fast path
FR-CAT-3 names: locate the camera's own embedded JPEG, decode a few hundred
KB, downscale, orient. Never a demosaic. A file with no usable preview yields
none, which is not an error and simply leaves the grid to fetch one later.

The filing waits for the upload, and only the filing. The shard store is keyed
by `oc:fileid` (FR-NC-5) and that does not exist until the server has the
file — so the thumbnail is made from the local copy and held until an id can
be attached to it. One listing per folder supplies every id at once, rather
than a PROPFIND per photograph over a link that may be mobile data.

Best-effort throughout: a thumbnail that cannot be filed costs the grid one
preview fetch later, and failing an import over it would be the wrong trade.

dtourolleandClaude Opus 5 13d003b89d Let the curve widget plot whichever curve is asked for
An operation with four curves and a panel that draws one plot needs a way to
say which. The panel finds out the way it finds out everything else: the
points are faceted with the subject they act on, consecutive parameters
sharing a subject are one curve, and a widget spanning several of them gets
a selector over their names. Nothing in ui/ contains the word "red", and an
operation that grows a fifth curve arrives with a fifth chip.

The names ride on the panel rather than on the curve's row, because a Slint
model is compared by identity: a fresh list built on every parameter event
would make the row look changed every time, and rewriting a row rebuilds the
element holding the drag in progress. That is the hazard the in-place point
update already exists to avoid.

Which curve is on show is interface state, not an edit. It changes no pixel,
so it takes no history step, reaches no sidecar, and redraws nothing — the
photograph on screen is already right.

dtourolleandClaude Opus 5 49be1fe354 Give the library somewhere to type a keyword
A sheet over the grid, opened from the header beside "Add to collection" —
deliberately the same card, scrim and dismissal as the filing sheet, because
they are the same gesture applied to two kinds of label: pick the photographs,
then say what they are. A user who has filed a selection already knows how this
works.

A word the whole selection carries, a word only some of it carries, and a word
none of it carries are three visibly different marks. Half-applied shown as
applied would be a lie about photographs the user cannot see from here, so a
partial keyword draws a dash and says "3 of 12" beside it. Tapping a dash
completes the keyword rather than removing it, which is what it means nine times
in ten, and the tenth is one more tap away.

The vocabulary is answered against the selection in Rust and pulled when the
sheet opens rather than pushed on every selection change — the selection moves
on each arrow key and the sheet is shut for almost all of them.

Assign and unassign travel by name, so a word typed into the field and a word
tapped in the list are one path rather than two, and the sheet never has to
invent an identity for a keyword that does not exist yet.

One gap, commented at the call site: unlike a star or a flag, a keyword is not
queued to the image's sidecar, because the sidecar format has no field for one.
So it reaches the user's other devices through the catalog merge, and a deleted
catalog loses keywords where it would keep ratings.

dtourolleandClaude Opus 5 939f33a3a3 Say on the import page where the photographs end up
Three lint findings and the gap the third one was pointing at.

`Context::library_label` was dead: the page named the folder on this machine
and said nothing at all about the server, which is half of what the Import
button commits to and the half that takes minutes rather than seconds. It now
names both, and states the order — copied and verified here first, then
uploaded (FR-NC-7b) — beside the destinations rather than beside the button,
because someone watching a slow upload needs to already know the photographs
are safe on disk.

The label is cached when the page opens rather than read in `render`: reaching
it goes through the context closure to the account, and `render` runs on every
keystroke.

dtourolleandClaude Opus 5 96a7b405c2 Say which photograph the sliders are pointed at
Selecting a mask layer silently re-points about thirty controls at that layer's
chain. Same panel, same order, same sliders, different meaning — and the only
thing that said so was a sentence in the panel above, which a photographer
reaching for the exposure slider has no reason to read. An exposure change
lands on the whole frame when it was meant for a face, or the reverse; both are
silent, and both are discovered later. `ui-navigation.md` §1.1 calls it the
dangerous one and it is: the others in that document cost time, this one costs
work.

The remedy is the classic one for a modal fault — make the mode visible — and
the application already had the pattern. Crop arms a canvas interaction, draws
an overlay, gives the column one job and is left by the control that entered
it. Local masking is the same animal built as a peer panel, and that is what
created the ambiguity. So `crop-mode` stops being a bare boolean and becomes
one value of a three-state mode, which is the point: two modes could both be on
before, and now that is not a state the interface can be in rather than one it
is tested against.

**One strip, not two.** The mode control was going to sit beside the group
strip that filters the adjustments, which is two controls above one column
answering the same question — what am I working on. They are one control now,
`Crop · Local │ All · Light · Colour`, which is the shape Lightroom Mobile's
bottom strip has for the same reason. The two halves are different kinds of
state and are drawn differently: a mode is a chip that fills with the accent
when it is on, a group is a word with a rule under it. That difference is what
lets both be read at once, which they routinely are — picking Light while a
mask is selected filters *that layer's* chain and does not leave the mode.
Dropping the scope on a group press would be the same fault coming back from
the other end, and would make Light mean two things depending on where it was
pressed.

The strip stays pinned above the develop column rather than moving to the top
of the canvas as the document proposed. The half that filters the column
belongs to the column, and the photograph is the subject. The canvas keeps one
button, which now names the mode it leaves rather than saying "Done" — that was
unambiguous with one mode and would not be with two — because the column can be
closed on a narrow window and no mode may be inescapable.

Entering a mode is a side effect, so Rust owns it rather than the strip writing
the property: crop drops the zoom, local turns the overlay on, and leaving
clears the selection. That last one is the fix. The "Overlay" and "Select"
toggles are gone because they armed things that are simply what the mode *is* —
a mode that has to be switched on separately is one you can enter and have do
nothing. Escape and the Android back gesture join `back_step` as one
`LeaveMode` rather than a second exit concept, and the mode is left before the
zoom is: it was entered later, and it is the bigger step back.

The heading is where the scope goes. Not a caption beside the panel, the
heading *of* the panel that changed — `ADJUST` becomes the layer's name, the
same string the selected row in the stack shows. That is the difference between
describing a hazard and removing it.

**Handles on the photograph.** A linear or radial mask could be created and
then not moved, so a radial sat at the centre of the frame at its default size
for ever. Three faults stood in the way of drawing one.

The first is that a gradient did not render at all until the model had run. The
rasteriser was built on the way out of `segment` and the array's size was read
*off* the segmentation, so a gradient added to an unsegmented photograph
produced nothing — silently, in the same way exports and thumbnails once did:
the shader still emits the layer's block and the empty placeholder multiplies it
by zero. The proxy size is a property of the photograph. Both are derived from
it now, and deliberately at the same size rather than by coincidence, because a
subject's distance field is sampled against that array.

The second is hit-testing. A handle is drawn in output coordinates and stored
in source ones, and between them lie the crop, the zoom, the pan, the
straightening and the turns. `Framing::source_at` is `wgsl_prologue` evaluated
on the CPU, kept in that file beside it so that keeping the two in step is one
file's problem — a handle mapped through anything less drifts off the mask the
moment the view moves, which is exactly what masks are rasterised in source
space to avoid.

The third is that a drag is a displacement, not a destination. Each handle
answers to the movement of the pointer since the press, applied to where the
mask was when the press landed. Snapping the handle to the pointer instead
jerks it by up to half a touch target on the first press, and the target is
finger-sized because a tablet has no hover to reveal a control and no modifier
to qualify it.

A ramp gets three handles — centre, width, angle. An ellipse gets three too:
centre and one per semi-axis, the major one carrying the direction as well as
the length, because where an axis is put says both. It had a fourth, and it is
gone: standing off the shape by a fixed distance, the rotation arm began
outside the photograph at the size a new radial is created at, so the first
thing anyone saw was a control they could not reach without first shrinking the
mask.

Two faults here were found by looking at the screen rather than at the source,
both of the kind that cannot be found any other way. A `1px` rule with a size
and no position is *centred* by Slint, so the seam between the photograph and
the column was a hairline down the middle of the panel, through the histogram
and every slider under it — twice, once in `app.slint` and once in
`AdjustPanel`. And handing Slint a fresh model for the handles on every pointer
event made the repeater rebuild its items, taking the `TouchArea` holding the
gesture with them: the handle jumped once and then went dead under a finger
that was still down. `develop.rs` carries the same warning about the parameter
rows, where it broke slider drags; the model is rewritten in place now.

The tests worth having are the ones about ambiguity and about the map. That the
same row reads the frame's value, then the layer's, then the frame's again is
§1.1 in one assertion. That dragging a handle onto another gradient's matching
handle *produces* that gradient closes the loop between the two directions of
the framing map, through a view that is cropped, zoomed, panned, straightened
and quarter-turned at once — a one-legged map is invisible when the framing is
neutral, because then both legs are the identity.

Not done here: the histogram still reports the whole frame while the sliders
edit a layer. That disagreement is real and is N3's, which this unblocks. The
strip has room for a Brush entry beside Crop and Local when the painted masks
land in the core, and it needs nothing here but the canvas interaction.

The develop column's panel is a Rectangle, not a layout — a note four lines
above explains why it is not an `if`. Two children of one therefore both sit
at its origin, so pinning the strip beside the Flickable overlapped them and
collapsed the whole develop view to a sliver.

Wrapped in a VerticalLayout. The strip is pinned by being outside the
Flickable rather than by any coordinate, which is what keeps it working at
any column height.

Caught by screenshotting the device rather than by the build, which was
clean throughout — a Slint layout fault is invisible in the source and
obvious the moment anyone looks.

dtourolle 9a7b045df4 Pin the group strip where it can be found
It was inside AdjustPanel, which on a tablet put it below five other panels
and off the bottom of the screen: present, working, and unreachable without
scrolling past everything it exists to save you scrolling past. A control
that answers "where is everything else" cannot itself be somewhere else.

Now a GroupStrip above the scrolling column, so it never scrolls away. It
still names no group — the strings arrive resolved from whatever the
operations declared themselves to be about.
2026-08-22 10:46:35 +02:00
dtourolle 924a837389 Group the panel by what operations say they are about
A strip of groups over the adjust panel — Light, Colour, Detail — derived
from the attributes the operations declare. `adjust.slint` names none of
them: the strings arrive resolved and the panel only draws them, so a new
operation joins the right group by saying what it is and this file does not
change (FR-DEV-3a).

A group nothing carries is not offered, so a tab never opens onto nothing.
Geometry is left out because its one operation prefers an on-canvas widget
and is skipped by the row builder — a Geometry tab would be empty while
`GeometryPanel` holds the real controls. The strip appears only when there
is more than one group to choose between; a single tab is a control with one
option.

The selected group is underlined rather than filled. The accent means
*modified* everywhere else in this interface, and spending it on "which tab"
would blunt the one signal the panel has.

**The trap, and it nearly bit again.** `op_index` on a row counts over every
capability, not over the ones a filter kept — it is how a row routes back to
the core. Renumbering it while filtering would make a slider drive a
different operation, which looks like a rendering fault rather than a
routing one. `rows_filtered` keeps `enumerate` over the full list and only
`group_head` is a position within the emitted rows; a test moves a value
through a filtered row and checks it lands where it was asked to.

Six tests, including that a nonsense index falls back to showing everything
rather than to showing nothing.

dtourolle a881fa3693 Use transform-rotation, which is what Slint calls it now
rotation-angle is deprecated in 1.17 and was the only warning the build
still emitted.
2026-08-22 09:03:59 +02:00
dtourolle e7dbdeb21f Keep the overlay on the photograph when the view moves
The overlay is a source-space picture; the canvas beside it shows whatever
the crop, the zoom and the pan selected out of that same space. Drawn whole
it stayed frame-sized while the photograph moved underneath, so zooming in
left a map of the whole picture stretched over a detail of it.

It now reports the visible rectangle as a clip, which the compositor
applies for nothing. Resampling on the CPU instead would mean rebuilding a
megapixel image on every frame of a drag, and putting it on the GPU would
add a second texture to keep in step with the view.

Pushed from the render path rather than the panel's sync: a pan changes no
mask and no row, so nothing else needs to run, and rebuilding the row
models on every frame of a drag would be waste.

Straightening is handled by rotating the image. A quarter turn or a flip
permutes the axes and a clip rectangle cannot say that — noted where it
happens rather than left to be discovered. The proper fix is to run the
overlay through the same shader prologue the photograph goes through, which
is the right answer and a larger one than this.

Four tests, and the one that matters asserts the clip *narrows* when zoomed
— which is precisely what it failed to do.
2026-08-22 08:53:02 +02:00
dtourolle 37f63edbf9 Take the watershed out of the product path
It does not work on a photograph, so nothing should offer it. `Segmentation`
is now one model pass and what it recognised: no region field, no merge
tree, no label upload, no granularity slider, and no readback of the whole
proxy to build a graph that collapses.

A click means "the object under the cursor". The region-selection path went
with the hierarchy it indexed — including the shift-click add/subtract,
which has no meaning for a whole object and would have been a modifier that
silently did nothing.

The passes, the hierarchy and the semantic prior stay in `dr-gpu` and
`dr-segment`, tested and documented. It is the *merge criterion* that
fails — the saddle is the minimum gradient along a boundary, so one weak
pixel merges two regions and real gradient noise puts a weak pixel on every
boundary. That is one function to replace, and the evidence for replacing it
is worth keeping. What is gone is the wiring, the option, and the control
that offered a user a choice with no outcome.

`MaskSource::Regions` remains in the pipeline: it is tested, it round-trips
through the sidecar, and a stored layer that names regions must still load
and be reported stale rather than failing to parse.
2026-08-22 08:39:17 +02:00
dtourolle 6163b63895 Put the edge controls where the mask is
Feather, falloff, grow/shrink/close/open and their amount, on the selected
layer. All four read the one distance field, so all four are live — nothing
recomputes except a compound morphology, and the session keys on that
separately so a feather drag rebuilds nothing.

Shown only for sources that go through the distance field. A gradient
carries its own falloff in its geometry, and offering a second one would be
two controls fighting over the same edge.

Picking an operation seeds a small amount if none is set. Selecting "Grow"
and seeing nothing happen would read as a broken control rather than as a
radius of zero.
2026-08-22 08:39:17 +02:00
dtourolle ee10097435 Mask the subject the model found, not the regions underneath it
The watershed hierarchy does not survive a photograph, so local masking
stops depending on it. A layer can now be one recognised object, and the
object's own coverage is the mask.

`Options::watershed` defaults off. It costs ~80 ms plus a full-resolution
readback to produce a ladder that collapses, and paying that on every
photograph buys a control that misleads. Kept switchable rather than
deleted: the passes and the hierarchy are correct in themselves and it is
the merge criterion that fails, which is a change to one function.

Masks now rasterise in **source** space at proxy resolution and are sampled
by the composed shader after the framing map. That fixes a real bug: they
were rasterised in output space, so zooming slid the photograph underneath
a mask that stayed pinned to the viewport, and cropping moved every
adjustment to a different part of the picture. Doing it this way also
leaves the framing map in exactly one place — a second copy in the mask
shader would have been a second thing to keep in step, failing only when
straightened.

A subject is stored as identity, not pixels: the mask is megabytes and is
reproducible by running the same model over the same image, so the sidecar
carries the index, the class and the score, and the session carries the
pixels. The class is there to be checked — if instance 3 comes back a "car"
where it was a "dog", something changed and the layer is stale rather than
silently masking the wrong thing.

The overlay now draws instances and is transparent everywhere else. The
region version covered every pixel and so hid the photograph it was drawn
over; the question it exists to answer is whether an outline follows the
subject, which you can only answer by seeing both.

`examples/local.rs` is the worked example: subject in colour with the rest
monochrome, and the subject lifted out of its background. Run on a 5472x3648
CR2 it finds two people and two cars, and the colour-pop keeps her hat and
hair while the wall and grass behind go grey.
2026-08-22 08:39:17 +02:00
dtourolle 9b4f0815e5 Show the regions, click one, and adjust it
The local panel sits above the adjust panel because it decides what those
sliders act on; below it, a photographer would set an exposure and only
then discover which scope it landed in. Selecting a layer re-scopes the
existing controls to that layer's chain — there is no second set of
sliders, and there must not be, or every operation added to `ops/` would
need a local twin.

The overlay is drawn over the canvas rather than blended into the render,
because it is a diagnostic and not an edit: it must not reach the
histogram, an export, or the texture handed to the compositor. Nearest-
neighbour always — the map's values are *names*, so smoothing between
region 4 and region 9 invents a colour belonging to neither and softens
exactly the edge the overlay exists to show.

Picking gets its own touch area above the pan handler. Panning wants
press-drag-release and picking wants a click; interleaving them in one
handler is how a drag ends up selecting a region the user was scrolling
past. Shift is tracked as window state because a TouchArea's click carries
no modifiers.

Three states a layer can be in are worth distinguishing, and each has a
different remedy: stale needs re-segmenting, "no adjustment yet" needs a
slider moved, and the ordinary case needs nothing said. A bare selection
renders nothing and looks identical to a broken mask, which is the first
thing a new user will hit.

Known rough edge, commented where it happens: segmentation blocks the UI
thread for about half a second. Moving it to a worker needs the develop
session — GPU resources behind a RefCell shared with every callback — to
be reachable from another thread, which is a restructuring rather than a
change to the call. The button says "Finding regions…" first so the stall
is announced rather than looking like a hang.
2026-08-22 08:39:17 +02:00
dtourolle 3085ec4d2e Leave the stars on screen on a touch device
**Hover is not something a finger does, but Slint reports it anyway.**
`has-hover` goes true for any pointer event carrying a position, a touch
press included, and false again on the `Exit` that follows the release.

So the rating strip did appear on a tablet — for exactly the length of a
tap. It flashed on under the finger, vanished as it lifted, and the tap
carried on through to the cell and opened the photograph. An unjudged
frame could not be rated from the grid at all. The previous fix stopped
the strip disappearing when a *pointer* moved onto it; this is the same
symptom with a different cause, and hover was the wrong signal in the
first place.

The strip now stands open where the session is a touch one. That is
seeded from the platform rather than inferred, because inference needs a
press to reach a cell and a quick flick never delivers one — the Flickable
claims the gesture before the delay it would forward after — and a
control that only appears once the finger is down has appeared too late
to aim at. The grid still latches on the first non-zero touch id it sees,
which is what covers a touchscreen on the desktop.

One-way on purpose: a tablet with a mouse plugged in keeps the strips
once touched, which is the harmless direction to be wrong in. The
alternative is chrome that comes and goes as the user changes hands.
2026-08-21 22:35:14 +02:00
dtourolle 2fba685e16 Make a pinch zoom the grid and nothing else
Two faults left over from making the gesture reach the grid at all.

**It still opened photographs.** Checking the finger id stops the
synthetic release Slint emits when the *second* finger lands, but not the
other end of the gesture: lifting one finger of two leaves the other one
down, and Slint replays that survivor as a fresh `Pressed` on whatever is
under it — which is how it hands the pointer back to ordinary handling.
Under it is a cell. So the cell was selected, and lifting that last finger
was a complete, well-formed click on the same finger that pressed. No
part of the event stream distinguishes it from a real tap, so the grid now
remembers that a pinch just happened: a latch raised when the gesture
starts and lowered a beat after it ends, during which cells take neither
presses nor clicks.

The press that *opens* a pinch is undone rather than suppressed — it has
already happened by the time a second finger makes it a pinch. Undoing it
has to be exact, or a cancel that restored the selection but left the
anchor moved would make the next shift-click select a run from a cell
nobody pointed at, so capture and restore are a tested pair.

**And it was not smooth.** Two reasons. The pinch was thresholded into ±1
steps of 25%, so the grid lurched and then sat still; it now takes the
ratio since the last update and tracks the fingers, with the drawn cell
still landing on whole column counts because the columns divide the
width. And `zoom-cells` was the one geometry change still reloading
inline — a full catalog re-read, 360-row model rebuild and thumbnail
batch per step, on the thread drawing the frame. It goes through the same
settle timer as the rest now.
2026-08-21 22:03:46 +02:00
dtourolle 6ae0af3f72 Swipe up in develop for the photo roll
Develop opens one photograph. The grid handed over a path and nothing
else, so `index` and `total` were pinned to "1 of 1" on the way in and the
only route to the next frame was back to the library, find your place,
tap again. Fine once; intolerable through a set of forty, which is the
situation the develop view exists for.

The roll is the grid's already-loaded window along the foot of the
canvas. Swipe up to bring it out, swipe down to put it away — the sheet
gesture, already in the hands of anyone who has used a phone — and a
handle is drawn at the edge so the gesture is discoverable rather than
folklore, and so a pointer, which has no swipe to make, has a way in.

`SwipeGestureHandler` wraps the strip rather than sitting over or under
it, which is what it is built for: it delays a press the way a Flickable
does, forwards it to the children if no swipe develops and claims it once
one does, so a tap reaches the thumbnail and a drag does not. It covers
only the band along the bottom — above that, a drag still belongs to the
photograph, for panning and for the crop.

Picking goes through the same path a cell click does, so the outgoing
edit is persisted before the next image loads. The strip marks what is
open and scrolls to keep the mark in view.

The position readout now says where in the *library* the open photograph
sits rather than "1 of 1". Set after the open rather than before, since
the generic open path resets it — and given as the library ordinal, not
the row in the loaded window, which is an artefact of how much has been
paged in and would jump about as the window moves.
2026-08-21 21:10:44 +02:00
dtourolle c72f197880 Stop a row of buttons deciding how wide the grid is
**A Slint layout cannot be narrower than its children's minimums.** Given
less room than they need it lays them out at those minimums, lets the row
run past the edge — and reports the oversized minimum upwards.

That second half is what made this more than cosmetic. The header, the
filter chips and the grid are siblings in one VerticalLayout, so the
widest row's minimum became the whole view's minimum: `LibraryGrid` was
laid out wider than the window. The grid then measured itself against
that inflated box and sized its columns to fill space that was off the
screen, so the right-hand column was cut by the edge no matter what the
tiling arithmetic did. Fourteen filter chips do not fit across 768
logical pixels, so that was every tablet in portrait.

It also explains why opening the collections sidebar did not reflow the
grid. The view was already pinned at a minimum wider than the window, so
taking 232px away for the sidebar could not shrink it — it just clipped
more of it.

Each of those rows is now a horizontal Flickable. A Flickable's own
minimum is nothing, since it exists to be smaller than what it holds, so
none of them can inflate anything — and the controls past the edge became
reachable instead of merely absent. Applied to all four: the library
header, the filter chips, the compact action row disclosed by "More", and
the develop strip.
2026-08-21 21:00:49 +02:00
dtourolle 90d6e551b3 Give the develop strip room for its controls on a tablet
The render backend, the layout class and the frame rate are developer
readouts, and they were sitting in the middle of the one strip that also
carries the way out of develop, the undo pair, the panel toggle and
export. A HorizontalLayout given less width than its children's minimums
does not shrink them — it runs off the end.

A tablet in portrait is 768 logical pixels, which is not enough, so
everything from the panel toggle rightwards was pushed off the right-hand
edge. Below the breakpoint the develop column is *also* closed by
default, so a toggle that could not be reached meant the column could not
be opened at all — and copy and paste live in that column. That is the
whole of "I have no idea how to copy a setting on Android and apply it to
other images": there was no way to.

The three readouts now collapse to zero width below the breakpoint. Width
and not an `if`, because this strip is inside the layout that `expanded`
feeds and a conditional child here is the shape that has already caused
binding loops in this file — and because a `visible: false` child still
takes its slot in a layout, so hiding alone would have freed nothing.
2026-08-21 20:38:48 +02:00
dtourolleandClaude Opus 5 3cfa78cde2 Give the app a face and a name on the launcher
There was no icon anywhere, and on Android that was not a missing line in the
manifest. `aapt2 link` was being handed a manifest and nothing else, so the
APK carried no res/ and no resources.arsc — there was no table for an
`@mipmap/...` reference to resolve against even if one had been written.
Packaging now compiles the resource tree first and links the result in, which
is the two steps aapt2 insists on: link reads compiled input only, never a
directory.

That absent table is also why the launcher caption was blank, which had
looked like a second, separate bug. `android:label="DarkRoom"` was there and
correct the whole time, and Settings' App info read it fine; the launcher
could not, because resolving a label goes through the package's Resources and
there were none to open. Nothing about the label changed here. It came back
with the table under it.

`android:icon` then names one drawable for both icon generations, because the
`anydpi-v26` qualifier is what separates them. API 26 and up take the adaptive
icon and its three layers; the third of those, monochrome, is what lets
Android 13 recolour it rather than drop the app out of the themed set. Below
26 the same name lands on a density-matched PNG. `roundIcon` is deliberately
absent — a launcher old enough to read it is one that would ignore the
adaptive XML, and minSdk is 28.

The desktop icon is one `@image-url` on the window, and the only raster asset
in a UI that is otherwise entirely Path. The reasoning at the top of
icons.slint does not reach it: that is about glyphs a font might not carry,
and this image is never drawn by us at all. It goes to the window manager,
which wants pixels and composites them unmasked, so it is pre-shaped with
rounded corners rather than square the way the Android layers are.

Which exposed Slint's resource default. An `@image-url` compiles down to the
absolute path it had on the build machine, to be opened at runtime — already
wrong for Android, where the build happens under /work inside a container and
no such directory exists on the device, and wrong silently, as an image that
loads empty. `EmbedFiles` puts the bytes in the binary instead. It reaches
nothing else, since every glyph is a Path.

Verified on a device: the APK installs and the home screen draws both the
icon and "DarkRoom" under it, where before it had neither. In the link step
the adaptive icon resolves at all six densities and resources.arsc lands
uncompressed, which API 30 requires and the existing zipalign preserves. On
the desktop by reading _NET_WM_ICON off the running window — 256x256, as
handed over. Where that actually shows is narrower than it sounds, and the
comment says so: Wayland ignores the property in favour of matching app_id
against an installed .desktop file, which this repo does not install.

dtourolleandClaude Opus 5 6acc73a9fa Drag a collection onto another to nest it
The tree could be built nested but never rearranged: `set_parent` existed,
with its cycle check and its tests, and nothing in the UI called it. A
collection created in the wrong place stayed there.

Each row is already a drop target, so it becomes a `DragArea` too —
wrapped at the instantiation site the way the grid's cells are, which
keeps the row's own TouchArea nested underneath and a click still
selecting. `allow-move`, not copy: a collection has one parent, unlike a
photograph, which is filed in as many collections as you like.

The drop is handed only the target's id, so the source is remembered from
the press that precedes the drag — Slint builds the payload through a
`pure` binding, which must not have side effects. An image drag always
fills `dragging`, so an empty payload with a remembered row is
unambiguously a rearrangement; the row is taken rather than read, or a
later empty drop would move a collection nobody touched.

The library could be narrowed by rating, flag and availability, but not
by when a photograph was taken — so finding a fortnight meant scrolling
to it and holding position.

The range rides on `RatingFilter` for the reason `local_only` already
does: every query path threads that one struct, so the count in the
header cannot claim a total the grid does not draw. Undated images are
excluded whenever either end is set — they cannot be inside or outside a
span, and drawing them made the range look as though it had not applied.

Taken from the timeline rather than typed into two date fields. Finding
the period is what the histogram is for, and having found it the user
should not have to read the dates off the axis and key them back in.
The histogram keeps drawing the full extent while the range is on, or
there would be nowhere to widen back out from.

dtourolleandClaude Opus 5 dea826811e Render a blown highlight white instead of magenta
Every clipped sky came out bright pink. Measured, not guessed: developing
_MG_8596.CR2 and looking at the export, the subject renders correctly and only
the saturated region is wrong.

A fully clipped pixel reaches the shader as (1, 1, 1) — three photosites that
stopped counting, carrying no colour at all. The as-shot multipliers are not
neutral, so balancing sends it to (1.93, 1.00, 1.68) on this body, and the
camera matrix turns that into R 2.88, G 0.51, B 2.03. Red and blue clip at
one; green, whose matrix row is far less positive-heavy, does not. Red and
blue high with green low is magenta.

Nothing upstream was at fault, which is why the two previous attempts missed
it: the white balance is correct, the matrix is correct, and the sensor
normalisation is correct. The input simply was not a colour, and correct
arithmetic on a non-colour produces a confident wrong answer.

So saturation is detected before the balance is applied — the last 1.5% of
range, smoothstepped rather than switched, because a hard threshold draws a
visible rim around every highlight and a backlit edge on skin is where that
shows. Above it the pixel is pulled to the neutral of its own brightness, so
it keeps its luminance and loses only the cast.

Verified end to end on the file itself: the sky is white, the skin, the black
dresses and the stone are unchanged.

dtourolleandClaude Opus 5 d2024da368 Scroll the develop column as one, histogram and all
Only the sliders scrolled. The capture metadata, the histogram, the geometry
controls and copy-and-paste all sat above them in a fixed layout, so on a
280px column in portrait they took the height the sliders needed — and the
histogram, which is the instrument the sliders are judged against, could
neither be scrolled to nor scrolled past.

The Flickable moves out of `AdjustPanel` and around the whole column. Nesting
one inside the other was not an option: a slider drag already has to be won
against one scroller, and a second would give it a third thing to be lost to.

`slider-dragging` becomes an `out` property for the same reason. The
arbitration is unchanged and still necessary — a track stands the scroller
down as soon as a finger touches it, or every attempt to drag a slider would
scroll the column instead — but the scroller obeying it now lives a level up.
The scroll gutter stays where it is, as padding inside the content: it is what
guarantees somewhere to put a thumb that means "scroll" and nothing else, and
it matters more now that it serves the entire column.

Touch multi-selection in the grid, filing a selection into a collection
without a drag, and taking a collection offline from a held row.
2026-08-17 12:27:49 +02:00
dtourolleandClaude Opus 5 d913e50948 Select photographs with a finger, and take a collection with you
Two things a tablet could not do. Both existed for a pointer and had no
touch form at all, which on Android meant the collection sidebar was
somewhere to look at rather than somewhere to file into.

**Selecting more than one.** Ctrl-click and shift-click are the only ways
into a multi-selection, and touch has neither. Holding a cell now enters
selection mode, where a tap toggles — reported to Rust as a ctrl-press, so
it goes through the same `apply_press` as everything else rather than
growing a second copy of the selection rules. A double tap takes the run
between where selecting began and there: the touch form of shift-click,
and the reason the anchor from *before* the double tap has to be
remembered, since both of its taps move the anchor onto the cell being
tapped. A "Select" button does the same thing where a gesture would go
undiscovered (FR-UI-4).

**Filing without a drag.** A one-finger drag beginning in the grid belongs
to the Flickable that scrolls it — that is the arbitration working, not a
bug to route around — so the selection can now be filed from a sheet
listing the sidebar's own rows. Copy by default, as the drag has always
been; moving out of the collection being shown is a switch, because it is
the one that takes something away.

**Taking a collection offline.** The machinery was there and reachable only
by scoping the grid to a collection and finding a button behind a
disclosure. Holding a collection's name now asks the question directly, and
the tray on a row and the header button ask the same one — three
affordances doing two different things is how a user comes to avoid all
three. The question is asked rather than a toggle flipped because both
answers are expensive: one downloads gigabytes, the other deletes them, and
the counts and sizes go in the buttons where they are read before the tap.

`Cache::release` is new and is the destructive half `unpin` deliberately is
not. "Remove the local copies" is asked by someone whose device is full,
and withdrawing a promise while leaving the bytes for a future eviction to
notice is not an answer to it. It unpins before forgetting, or the next pin
fetch would dutifully download everything it just deleted.

The sidebar's trays read `tier_actual`, never `tier_desired`: the question
is whether these will open on the aeroplane, and a pin whose download has
not run yet answers no.

dtourolleandClaude Opus 5 44f0a4971b Show the folder picker on the platform that needs it most, and upload at once
Two faults, both of my own making, reported from the tablet as "I cannot
select a location" and "it does not upload".

**The picker button was gated on `target-selected == 1`.** That index was
Remote's position while both targets were offered. Making the target list
platform-aware narrowed Android's to Remote alone, so Remote became index 0
and the button disappeared — on the one platform where the picker is the
*only* way to set a destination, since a device folder is not reachable there
at all. It is gated on a boolean derived from the target now. An index into a
list whose length varies is not a fact about the target, and writing it as one
is what made a correct change break the thing it was meant to fix.

**A queued export waited for a sync pass.** Staging first is deliberate — an
export is finished on disk the moment it is written, and offline is then just
a longer queue — but nothing drained the outbox until the next sync, so
"Queued for Exports" sat unchanged and read, fairly, as an upload that never
happened. A finished batch that wrote anything now drains immediately. The
sync-pass drain stays: the first makes an upload feel immediate, the second is
what eventually delivers the exports made in a tunnel.

Committed without the parallel session's in-flight collection work, which is
mid-save and does not compile; verified by stashing it and building this tree
alone. 281 dr-ui tests pass, clippy clean.

dtourolleandClaude Opus 5 a8b28136a6 Merge the batch export, and settle the seven-branch merge
Resolves the last of the parallel work. Two conflicts worth recording,
because both were semantic rather than textual:

`render_for_export` gained a colour space on master while the batch branch
was rewriting the single-image export path around it. Kept both: the batch
request supersedes the synchronous path, and the space still has to be chosen
at render time because the conversion happens in the shader before the clip to
0..1. `render_open_frame` takes it as an argument rather than reaching for a
controller it does not hold.

The map-wait moved into `readback::await_mapping` on one branch while another
was editing the constant it used, so `READBACK_POLL_LIMIT` survived the merge
with no callers. Removed rather than left for clippy to find later.

1164 tests pass, clippy clean, fmt clean. Traceability 53.0% -> 54.3%.

dtourolleandClaude Opus 5 7d3c8c521f Export a whole selection, on a thread that is not the interface's
The export button rendered, resampled and encoded a 24 MP frame on the UI
thread and the window was dead for all of it. That was written down as a known
compromise, on the grounds that a batch is what makes the wait intolerable
rather than merely noticeable. This is the batch, so the compromise comes due.

The grid's selection now exports (FR-EXP-7). A worker thread takes a clone of
the `GpuContext` — an `Arc` pair over a device and a queue — and opens each
photograph for itself: fetch, sidecar, decode, demosaic, render at full size,
resample, sharpen, encode, write. Nothing of that touches the interface, which
keeps drawing throughout, and the progress goes where every other background
job's does: one row in the activity register, with a count and a bar.

Why the worker does not borrow the session it could have had. A
`DevelopSession` owns the `AdjustPass` the canvas renders from, so handing it
to a worker would stop the develop view drawing for the length of the batch —
the same freeze, moved. Opening a session per image instead costs a
`Demosaicer` and an `AdjustPass` each time round, and the pipeline cache is
per-pass so the composed shader is recompiled per image rather than once for
the run. Against a full-resolution decode, render and encode that is a few
percent, and it keeps this file out of the pipeline `develop` owns. A reusable
export pass is the obvious next economy if a profile ever says so.

The open image is the exception, and it is why the develop button is not simply
a one-image batch. Its edit lives in the interface's session and may not have
reached a sidecar yet, so a worker that re-opened the file would export the
saved version rather than the one on screen. That frame is therefore rendered
by the caller and handed over as `Source::Rendered`; everything after the
render — the Lanczos reduction, the encode, the write, which is the larger half
of the wait and all of its variance — still leaves the UI thread. So the
develop export is no longer synchronous, but it is not fully off-thread either,
and the doc comment says so rather than claiming otherwise.

Cancellation (NFR-ARCH-3) is an `AtomicBool` read between stages, and the
export button becomes the cancel button while a run is live — a batch that
could only be stopped by not touching the selection would be a trap. Waits on
another worker use `recv_timeout` rather than `recv`, so a cancelled batch
sitting on a forty-megabyte download gives up within 100 ms instead of when the
transfer finishes. The honest bound is worse than that: a frame already in
render has no interior stopping point, so the worst case is one image. Closing
that needs the render itself to become interruptible, which is NFR-ARCH-2's
scheduler and not a finer poll here.

Failures are per image and typed (NFR-ARCH-4). One unreadable body, one folder
that cannot be written, one server that went away — each is a message on the
channel, a line in the log, and a count in the summary, and the batch carries
on. A run with any failure keeps its row until it is cleared, because that is
the row somebody came to the list to find; a cancelled run does not, because
they asked for it.

Two collisions that look alike and are not. `CollisionPolicy` is the user's
answer to "a file of this name was already there", and Overwrite is a fine
answer to that. It is not an answer to "the frame I exported four seconds ago
was also called this" — two folders in a library each holding an IMG_0001 is
ordinary — so a name the run has already issued is always stepped past whatever
the policy says about the folder. Both halves are held by tests.

Supporting changes, each smaller than it sounds. `open_session` comes out of
`load_bytes` so the worker shares the JPEG-versus-RAW routing rather than
carrying a copy that would drift; the half that builds a `slint::Image` stays
behind, where it belongs. `LibraryController::selected_image_paths` answers
from the catalog rather than from the loaded window, because selection is by id
and survives a scrub — a selection made before scrolling routinely names
photographs no row holds. `cache_context_for` takes an id for the same reason,
so a batch reads the originals cache instead of re-downloading three hundred
files. `format_date` is shared so `{date}` and the timeline agree about what
day a photograph was taken.

Left undone, deliberately: the batch is sequential, where FR-EXP-7 asks for all
available cores. Four full-resolution frames in flight is tens of megabytes
each and a straightforward way to exhaust a tablet, and the GPU is shared with
the interface in any case. Also undone: exporting with a chosen preset rather
than the current export settings — that is FR-EXP-5's machinery, which does not
exist yet.

dtourolleandClaude Opus 5 0233df4bf2 See what the highlights are doing: a live histogram (FR-DSP-7)
Exposure, blacks and whites were set by eye. Nothing said a highlight had
blown — the canvas shows white where a channel is at 250 and white where it is
at 255, and the difference is the whole question.

**Counted on the GPU, not on the readback.** There is a full frame sitting in
CPU memory on every canvas update right now — `AdjustPass::read_output`, the
bridge spike S1 removes — and walking it would have been thirty lines and no
shader. FR-DSP-7 states the mechanism and not just the feature: "these derive
from a GPU-side reduction into a small buffer. Per-frame CPU readback of image
data is prohibited." A histogram founded on the bridge would be correct today
and deleted by S1, and would meanwhile be the reason the bridge could not go.
What crosses the bus here is 4104 bytes whatever the image size.

The reduction tallies into workgroup memory first and merges once per
workgroup. A photograph is not noise: a clear sky puts tens of thousands of
adjacent pixels in one bin, and contending for that single global atomic
serialises the dispatch.

**On the settled frame only.** `render_now` already knows whether a gesture is
still moving — `draft` is the flag `redraw` derives from `was_coalesced` — so
the dispatch and its transfer happen once when the slider stops rather than on
each of the forty frames a drag emits. Nothing is lost: a histogram flickering
past under a finger is not a reading anyone takes. FR-DSP-7 requires exactly
this, that it not extend the FR-DSP-3 frame budget.

Luma is weighted in 8.8 fixed point — 54, 183, 19, summing to 256 exactly —
rather than in floats. Not thrift: it makes the shader's arithmetic
reproducible bit for bit, which is what lets the test below be an `assert_eq`
against a CPU count rather than a tolerance. ARCH §6.13's line about integer
state, applied where it happens to also be free.

**What the numbers were checked against.** A flat frame must put all 4096
pixels in one bin and one only. A 256-wide ramp must occupy every level with
exactly the same count, which is what catches an off-by-one in the
quantisation — a `floor` where a rounding was needed shifts the whole
photograph one bin left and looks like nothing at all. And a 101x37 frame of
seeded pseudo-random pixels — deliberately not a multiple of the 16x16
workgroup, so the edge tiles run off the image — is compared slot for slot
against a second, obvious CPU implementation. Exact equality, no tolerance.
The CPU version is a deliberate reimplementation rather than shared code: the
bugs worth catching here are ones shared code would commit identically on both
sides.

Above that, the presentation arithmetic is unit-tested headless, because it is
where a wrong answer is invisible. A histogram of the wrong shape looks exactly
as plausible as one of the right shape. So: 64 columns because it divides 256
and an uneven fold draws an even ramp as a comb; the peak excludes the end
columns, or a night scene scaled against its own black spike is a flat line
with no information in it; heights are clamped into the plot; and "0%" is kept
distinct from "<0.1%" and from "—", since an indicator reading "clipped" over
a figure reading "none" is a panel contradicting itself.

Clipping counts a *pixel* with any channel at an extreme, not a channel. Any,
because a blown red has no gradation left in it however much green and blue
still hold — and it is the saturated highlight, the sunset and the red jersey,
that clips first and recovers worst. Per pixel, because counting channels can
report 200% of a frame clipped, and a percentage above 100 is a readout nobody
trusts again.

Two affordances for it, which NFR-A11Y-3 asks for: a bar standing at the end
of the plot the tones are piling against, and a figure saying how much. Either
alone reads.

The panel sits directly under the capture metadata and above every control,
because it is what the controls are judged against. It is hand-built rather
than generated, and ARCH §4.3a is untroubled: a histogram is not an operation
— no parameters, changes nothing, answers a question rather than asking one —
and nothing in it reads a parameter out of a descriptor.

Three plot colours and a neutral luma trace join the palette. That is the
swatch's exception rather than a second one: a per-channel histogram has to
say which channel, and no achromatic treatment distinguishes red from blue, so
the hue is data exactly as the image beside it is. Held well back from full
strength for the reason the theme preamble gives.

The bounded, non-parking map wait moves out of `AdjustPass` into
`readback::await_mapping`, shared with the histogram's transfer. Thirty lines
of load-bearing reasoning about frozen interfaces and lost devices, and two
copies of it would have drifted.

The histogram describes the frame on the canvas, so it is in the output colour
space FR-DSP-7 asks for, and when zoomed it describes the visible region — a
photographer inspecting a highlight at 4x is asking about that highlight. A
device that cannot build the reduction loses the histogram and keeps the
photograph.

Still to do for FR-DSP-7: the pixel colour readout under the cursor.

324 tests pass, clippy and fmt clean.

dtourolleandClaude Opus 5 7f524d2fd0 Give a mis-drag a way back
Develop edits now save themselves to a sidecar the moment you leave the
image, so until this there was no way to undo one — the mistake was
persisted and the only recourse was to remember the old number.

The history is a stack of snapshots, because the edit graph is already
plain data: `Preset::capture` reduces it to what differs from default and
`Preset::apply` puts it back, so undo is those two calls and nothing else.
A command object per action, with an inverse beside it, would have been a
second thing every operation had to register — and operations are declared
in YAML precisely so that a new one needs no code written for it. A
snapshot cannot fall behind them.

The interesting part is coalescing. A slider drag emits an event per frame
and must be one step, not forty. Nothing in the interface reports a gesture
boundary — the same wall the render coalescing hit, and it is answered the
same way rather than by threading a "finger is down" out of every slider,
curve point and crop handle. What stands in for the boundary is the control
plus recency: changes to the same control within 700 ms amend one step.
Which control is "the same" is asked of the graph, not listed: an operation
whose declared presentation claims a parameter is one where a single
gesture moves several — a curve point carries an x and a y — so those
coalesce as one widget. Nothing in the history names the tone curve.

The compromise, and it is a real one: a control let go of and picked up
again within the window is one step rather than two. Buying the other
answer costs a gesture-boundary signal on every control, which is more
surface than the difference is worth.

The stack is bounded at 64 states for NFR-RES-1 — a develop session stays
open for hours. Sixty-four rather than a byte cap: what is being bounded is
steps a photographer would want back, and a byte cap would give the
elaborate edit the shallowest history, which is exactly backwards.

The session owns its history and every mutator records into it, so the
callbacks in `lib.rs` cannot change the edit and forget to — with a dozen
generic callbacks that would have been one press of undo away from wrong
every time a control was added. Opening a photograph makes its stored edit
the floor rather than a step: it is not work done in this sitting, and an
undo reaching behind it would discard a previous session's edit and then
save that on the way out.

Not yet done, from FR-DEV-5: history is per-session and in memory, and
there are no named snapshots. What mattered was that a saved mis-drag had
no way back at all.

dtourolleandClaude Opus 5 cb1d2be240 Choose the export folder by walking the server, not by typing it
The destination for a Nextcloud export was a text field. Nobody recalls the
exact spelling of a path three levels down, and getting it wrong does not
fail — `create_dir` makes whatever was typed, so a misremembered folder
becomes a new one at the root and the exports are somewhere nobody looks.

So it is picked the way the library root is picked, using the same
`FolderBrowser` model the launch screen drives: up, into, and "use this
folder", confirming the folder currently *shown* rather than one selected in
the list. Same rule in both places, so the phrase means one thing.

The model is shared; the worker is not. `settings_ui::spawn_folder_list` is a
near-twin of the launch screen's, because that one reaches into the
`LaunchController` for its session and reports onto the launch screen's error
line, while this one is handed credentials and writes to the settings page.
Factoring them together needs a function taking both controllers or a trait
implemented twice to abstract two call sites — more machinery than the twenty
lines it saves. What matters is shared already: navigation behaves identically
because both drive the same model.

The callbacks are wired in `lib.rs` rather than in `settings_ui::wire`,
because listing a remote folder needs credentials and the settings page holds
no session on purpose — it is reachable before a library is opened and must
not depend on one existing. With no account the picker says to sign in first,
rather than showing an empty list that reads as a server with no folders.

Details that are decisions rather than accidents: the picker opens at the
library root rather than at whatever half-typed path is in the field, which
would list nothing and look broken. The listing area is a fixed 180px, since a
folder with sixty children would otherwise push the rest of the settings page
off the bottom. "Up" is disabled at the root rather than hidden, so the row
does not jump as the user navigates. A failed listing leaves the picker open
on the folder it was showing — where the user had got to is not something to
discard over a dropped request. And the chosen folder saves immediately like
every other setting on a page that has no Save button.

The poll timer lives on the controller for the reason `LaunchController` keeps
its own there: a `slint::Timer` stops when dropped, so one local to the
function that starts it would be collected before the listing arrived.

Carries in-flight work from a parallel session — a segmentation pass in
dr-gpu, a sidecar cache, and the develop panel's continuing changes.

1020 tests pass, fmt clean. One clippy warning remains and is not mine:
`sidecar_cache::dir` is unused while that work is in progress.

dtourolleandClaude Opus 5 e00c99b864 Let a photograph leave: an export button, and a cache to leave from
dr-export could turn a frame into bytes and nothing could ask it to. This is
the button, and the place the bytes go.

**Everything is staged first.** An export bound for the server is written to a
local outbox and uploaded afterwards; offline is not a special case, it is the
same path with a drain that finds the server absent. Doing it the other way —
upload directly, stage only on failure — makes the failure path the one that
is rarely exercised and always broken, and a network drop mid-batch leaves
some exports existing and some not with nothing recording which. Staged first,
an export is finished the moment it is written and the upload is a promise
kept later.

The outbox sits beside the catalog rather than under the cache. dr_catalog's
cache already draws that line: passive entries are a convenience and go under
LRU, pinned ones are a promise and never do. An export awaiting upload is a
promise — the user was told it succeeded — and sweeping it for disk would
destroy the only copy. Bytes are written before the destination record, so a
kill between the two leaves an orphan the drain ignores rather than a record
pointing at nothing.

The status line says "Queued for Exports/2026", never "Exported to Nextcloud",
until it has actually landed. There is a test asserting that wording, because
the tempting shorter sentence is a claim the app cannot keep.

The drain runs on the sync pass, before the shards: a thumbnail shard can be
rebuilt from the originals and the catalog is an index, but a queued export
exists nowhere else.

`DevelopSession::render_for_export` renders the framed size rather than reusing
the frame on screen, which is deliberately viewport-sized (FR-DSP-1) — encoding
that would hand the user a soft, screen-sized file with nothing to say anything
had been lost (FR-EXP-9).

One compromise, recorded rather than hidden: the export runs synchronously on
the UI thread, so the window is unresponsive for the few hundred milliseconds
a full-resolution render and encode takes. Moving a DevelopSession and its GPU
pass to a worker is a larger change than one button earns, and it is batch
export that makes the wait intolerable rather than merely noticeable.

Still missing: the Nextcloud folder *picker*. The destination is typed into
Settings for now. `FolderBrowser` in launch.rs is already the reusable model
for it — it browses a remote tree and nothing about it is specific to choosing
a library root — but wiring it into the settings page needs a listing worker
and browser UI there, which is its own piece of work.

Carries in-flight work from a parallel session — presets, the develop copy and
paste, and the node schema's `presentation` and `enum` support. One misplaced
callback in settings_ui.rs is moved from `render` to `wire`: registered in
`render` it borrowed a `&SettingsController` into a 'static closure and would
not compile, and that file's own docs say render pushes properties while wire
connects callbacks.

992 tests pass, clippy and fmt clean. Traceability 48.3% -> 51.0%.

dtourolleandClaude Opus 5 e7130ff891 Give the library header somewhere to put six buttons
A tablet in portrait is 1920 physical pixels at density 400 — 768 logical,
which is below the 820 breakpoint, so the library was already taking the
compact layout. The compact header simply was not compact: one flat
HorizontalLayout holding a menu button, a title, three status readouts and
six buttons.

Slint's HorizontalLayout has no wrap and no overflow. Given less width than
its children want it shrinks each to its minimum and lets the rest run past
the edge, so "Change library" arrived as "Change li…", the readouts elided to
nothing useful, and the row overflowed anyway.

The six actions move into a `HeaderActions` component drawn in one of two
places: inline in the header when expanded, and in a disclosure row under it
behind a "More" button when compact. One component rather than two copies,
because the alternative is six buttons with their visibility rules and
callbacks written twice, and the copy that rots is the one behind a
disclosure nobody opens while testing.

The row closes itself when the window widens, so rotating to landscape does
not leave a stray toolbar behind. "More" is a word rather than an ellipsis
glyph: "⋯" sitting in a header of elided labels reads as one more truncation,
which is the failure this change exists to remove.

`LibraryGrid` takes `expanded` to decide, from the window width rather than
the device (FR-UI-1) — so a narrow desktop window gets the same treatment.

dtourolleandClaude Opus 5 151dcc3c02 Make a file out of a photograph
Export existed as a settings page and nothing else: format, quality, colour
space, five sizing modes, a filename template and a metadata switch, all
configurable in detail, and no way to produce a single file. dr-export is the
other half.

**It returns bytes and a name, and writes nothing.** An export has three
destinations with nothing in common — a path on Linux, a SAF document on
Android where there is no path at all (ARCH §6.9), and a PUT to a Nextcloud
folder — so a crate that opened the file itself would serve one of them and be
rewritten for the other two. The caller places the bytes.

Resize, then sharpen, then encode, in that order and for a reason: output
sharpening compensates for the softening the resample introduced, so its
strength scales with how much scaling actually happened, and sharpening before
shrinking would throw the result away. Lanczos-3, separable, with weights
computed once per output row — FR-EXP-4 asks for Lanczos or better because a
box filter turns a distant fence into moiré.

Collision handling takes the "is this name taken" test as a closure rather
than looking at a directory, because there is no directory it could look at
that works everywhere. That shape is not politeness toward Linux: Android's
createDocument renames on collision by itself and cannot overwrite at all, so
all three CollisionPolicy settings need the answer *before* anything is
created. Overwrite, Skip and Increment are each tested, and Increment gives up
after ten thousand rather than spinning against a destination that reports
everything as taken.

Three things are honest rather than done:

  - **Colour space.** sRGB only. The shader encodes and clips to sRGB before
    this crate sees a pixel, so tagging a file Display P3 would claim a gamut
    it does not contain. Refused with a typed error instead of mislabelled;
    honouring it is a pipeline change (FR-EXP-2).
  - **AVIF and JPEG XL.** No encoder. libaom and libjxl are C, ravif is slow
    enough to change what a batch feels like, and the settings page offers
    both because FR-EXP-1 lists them — so asking for one says so rather than
    writing a JPEG under a .avif name.
  - **16-bit TIFF** is a real 16-bit file carrying eight bits of information,
    because AdjustPass renders to Rgba8Unorm. Widened by *257, not <<8, so
    white lands on 65535 rather than a quarter-percent grey. Making it mean
    what it says needs the composer told what format to write.

Metadata is not written at all, which satisfies the half of FR-EXP-8 that
matters most: strip_location defaults to on, and a file with no EXIF block has
no GPS tag. Retaining camera and copyright when asked is not implemented and
cannot be faked by omission.

Also here:

  - `AdjustPass::export_pixels`, ungated where `read_output` is behind a
    feature. The two are the same transfer and opposites in intent: reading
    pixels back to *display* them is what ARCH §6.1 forbids and AC-8 asserts
    against, while reading them back to encode a JPEG is the only way a file
    has ever been made. Separate methods so the instrumentation can count one
    without counting the other.
  - `ExportTarget`, so a destination can be a folder on the server. On Android
    that is the only destination needing no platform work whatsoever — a PUT
    against create_dir, already on the RemoteBackend trait, behaving
    identically on both platforms. Switching target clears the destination,
    since a path is not a remote folder and carrying one across would offer to
    create a folder called `home` at the library root.

Verified end to end rather than by unit test alone: `cargo run -p dr-export
--example export` decodes a frame, runs the develop chain on the GPU at full
resolution, reads it back, and writes all five formats — 27 ms for a
full-size JPEG, 165 ms with a Lanczos reduction to 1200px. ImageMagick agrees
the 16-bit TIFF is 16-bit. dr-export cross-compiles clean for
aarch64-linux-android; all three encoders are pure Rust, which is why they
were chosen. 944 tests pass, clippy and fmt clean.

Not yet wired to a button. The develop view has no export action, so nothing
in the running app can reach any of this yet.

dtourolleandClaude Opus 5 65e6a96a65 Say what the application is doing, in one bar and one list
Every background job reported into a window property of its own —
library-thumbs-done, library-pin-total, library-syncing — which only the
grid ever read. A pin download that outlived the view it was started from
drew nothing at all once the user opened an image, and there was no answer
anywhere to "what is this busy with", because the answer was spread across
eight properties nothing collected.

They report to one register now (ui/dr-ui/src/activity.rs). It publishes an
aggregate, which draws a three-pixel bar across the top of the shell in
every view, and a row per job, which the settings page lists: scans,
thumbnail batches, pin and open downloads, sidecar uploads, the sync and
the trash. Failures stay on the list until they are cleared; routine
successes do not, or a scroll would bury them.

The handle removes a still-running job when it drops, so a worker that dies
mid-transfer takes its row with it rather than leaving the bar sweeping for
the rest of the session.

Also carries in-flight work from a parallel session — the drawn icon set
and the dr-pipeline ops split. dr-pipeline's build script does not compile
at this commit; ui/dr-ui does, with clippy clean and its tests passing.
