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 dce1e66746 Show which cell a shift-click is measuring from
The gesture had a hidden operand. A range runs from the anchor — the last cell
plainly clicked — to the cell shift-clicked, and nothing on screen said which
one the anchor was. A user who could not tell where the range was being measured
from had no way to predict what it would take and no clue why a wrong one came
out wrong; often the anchor is not on screen at all, which is itself the answer
to "why did that select so much".

The anchor is marked with an inner ring, drawn inside the selection ring rather
than in a colour of its own: it has to stay legible against a thumbnail of any
brightness, and a hue would read as a second kind of selection. It is an
ordinal, so it marks a row only while the photograph it names is in the loaded
window — off screen it marks nothing, which is the honest answer, and `anchor`
rides in the cell model beside `selected` so both are pushed by the one pass
that already keeps the grid in step with the selection.

dtourolleandClaude Opus 5 54f9cb54fb Take the whole run a shift-click names, not the part that happens to be loaded
Shift-clicking two photographs selected only the cells between them that were
in the loaded window. The grid is a window of a hundred or so over a library of
twenty thousand, and `apply_press` resolved the range against that window —
`ids[lo_row..=hi_row]`, clamped to what was there. Everything else in the run
had no id anywhere in the UI, so it was silently dropped. The user cannot see
that: the selection count is off screen along with the photographs, and the
gesture only announces itself when the drop files a dozen images instead of two
hundred.

The two ends are *ordinals*, and only the catalog knows what lies between them.
`read_ids_span` asks it, through the same predicates, the same rating filter and
the same ordering the window itself is read with — an ordinal names a photograph
only relative to an ordering, so a run taken through any other one is a run
through a different library. That ordering is now a constant, `GRID_ORDER`,
shared by the window, the trash's own order beside it, and the run: capture time
first, with the file name breaking ties and nothing more. A card written by two
cameras interleaves names that have nothing to do with each other, and what
"everything between these two" means to a photographer is a stretch of an
afternoon.

The query is reached through a closure handed to `CollectionsController` at
wiring time rather than a catalog handle, because the scope and the filter that
bound the run belong to the grid's controller. `apply_press` stays a pure
function of what it is given, which is what keeps the selection rules testable
with no library open — and the tests pass a run that reads a plain slice. Where
there is nothing to ask, the loaded window is still used: a poorer answer than
the catalog's and a far better one than a gesture that appears to do nothing.

dtourolleandClaude Opus 5 22325415b1 Fetch what is on screen before what is not
The other half of the blank bottom row, on a library still filling its
thumbnail store: the cells were in the model, and nobody had asked the server
for them yet.

A batch is fetched one image at a time, two round trips each, and it is
abandoned wholesale the moment the window moves. Issued in model order, the
front of that queue was the quarter-window of cells sitting *above* the view —
which nobody is looking at — and the back of it was the bottom of the screen
and the screenfuls below. So the last rows of the grid waited behind three
quarters of a window's worth of fetches for photographs off screen, and every
scroll threw the queue away and started over from above the view again. For as
long as the scrolling continued, the bottom of the grid could be starved.

The rows still address the model they were built against; only the order they
are asked for in changes. On screen first, in reading order, then the rows
below the view, then the rows above it. Below before above because that is
where the view is going — scrolling back over cells already fetched is served
from the store, and from `requested` without a fetch at all.

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.

The grid still jumped. Anchoring on `offset` was wrong for a reason this file
already states, a few hundred lines away: "the first *visible* ordinal, not the
window's start: the loaded window deliberately begins a quarter of a screen
above the view, so its first cell is one the user cannot see."

Two things made `offset` the wrong number. It is a screen-quarter above what is
being looked at, and by the point this runs it has already been re-clamped
against the new, smaller total — so seeking to it moved the view somewhere the
photographer had not been. A smaller jump than the original, and the same fault.

`resume_at` is what the grid last reported as its first visible image, which is
the photograph the person is actually looking at.

Deleting made the grid go blank and jump somewhere arbitrary. Two causes, both
of them the viewport being left behind by everything else that moved.

The Flickable is sized to the *whole* library so its scrollbar is a real
address into twenty thousand images. Delete some and that content gets shorter,
which leaves a view near the end scrolled past what now exists — cells sitting
above a viewport looking at empty space. Slint does not pull a Flickable back
on its own. (The clamp for that went in with the previous commit.)

The jump is the other half. Cells are drawn at their absolute place in the
library, `(i + offset) / columns`, and a delete re-clamps `offset` downward so
the loaded window still fills. Nothing touches `viewport-y`, so the same scroll
position now addresses different photographs and the grid appears to leap
somewhere unrelated.

`restore_position` re-anchors on the ordinal the view was showing, clamped into
what is left. Not on the deleted image's own position, which no longer exists,
and not on the top of the library, which would throw the scroll position away
on every delete — after removing one frame from a wall of twenty thousand, the
one you want next is the one that just moved into its place.

Only on a shrink, and the shrink is detected by reading `library-total` before
overwriting it. Re-anchoring on every load would fight a scrub, which sets
exactly this property to go where the user asked.

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.

Pressing "limit to range" did nothing, and the reason was two early returns
that sat above the line which shows the controls. If the catalog was not open,
or nothing in it carried a capture date, the handler returned before
`set_library_range_active`, so no state changed and nothing appeared.

Capture dates are read from EXIF as thumbnails load, so a freshly opened
library has none — the button was inert on exactly the libraries where someone
is most likely to go looking for a date, and it failed by doing nothing at all,
which is the hardest failure to report.

Underneath that was a smaller mistake with the same shape: whether the controls
showed was read from whether a range was set. The fields are how a range gets
set, so requiring one before they appear is a door locked from the inside. The
panel has its own state now, and the timeline span is a seed for the fields
rather than a precondition for them — no span means two empty fields waiting to
be typed into, which is a way to choose a range rather than a refusal to offer
one.

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 fbf286d504 Keep the mask when the photograph is closed
A local adjustment survived until the session ended and then did not exist.
Nothing reported it, because nothing had failed.

The sidecar format has carried masks since they were added, `Version::apply`
restores them into the graph, and `Version::update` captures them — that work
landed complete and was never called. The autosave writes `copy_settings()`,
which is a `Preset`: a map from (operation, parameter) to a number. A mask is
not a parameter. It is a rule about *where*, with a chain of its own, so it
fell outside the only thing being written, and the read path had nothing to
read.

The save now carries the stack beside the preset, on both the local and the
remote path. Deliberately not merged but replaced wholesale: this is the stack
as it stands, so a layer the user deleted has to leave the file too. Merging
two devices' stacks is `Sidecar::merge`'s job and belongs to sync (FR-NC-9).

A paste still carries no masks, and the `Option` is how that is said. Settings
travel between photographs; a mask does not, because it is drawn against one
frame and describes nothing on another — and `Scope` cannot express that,
since it filters parameters and a mask is not one.

The test fails against the old save path with "the mask must come back with
the photograph", which is the whole of the defect: not a crash, not an error,
just an edit that was not there in the morning.

dtourolleandClaude Opus 5 5807b67693 Caption a photograph with its name, not with how it is stored
A grid cell is about four words wide and `.CR2` spent one of them saying
something the photographer already knows: in a RAW library every frame ends
the same way, so the extension distinguishes nothing while taking room from
the part that does. The caption elides from the end under pressure, so an
extension can push the digits that actually identify a frame off the visible
part of its own label.

Dropped in the view, not in the model. `LibraryCell::name` keeps the true
filename and `remote_path` the full path, because both are used to find the
file again and a stem is not a filename.

The case it is wrong for, recorded rather than discovered later: a library
holding `IMG_1234.CR2` beside `IMG_1234.JPG` now shows two cells captioned
`IMG_1234`. They remain two rows with two thumbnails and two entries in the
info panel, and a RAW+JPEG pair is usually one photograph anyway — but the
caption alone no longer separates them.

Only the last dot goes, and only when something precedes it: `2026.08.23-a.dng`
keeps its dates, and `.hidden` keeps its leading dot, because that dot is how
the name starts rather than an extension.

dtourolleandClaude Opus 5 11a63fc7a8 Refresh the collection tree when a sync brings membership
New-York gained 127 photographs from the tablet and the sidebar went on showing
no number beside it.

Two reasons, and the second is why the first was never noticed. The sync's
completion handler reloads the grid and never rebuilds the tree — the scan
already does, and the sync merges the same tables. And the condition it reloads
under was `collections_gained > 0`, which counts collections, not members: a
sync that files 127 photographs into a collection both devices already had
gains no collection at all, so the count was zero and nothing refreshed.

`SyncReport` now carries `members_gained` from the merge report, and either one
rebuilds the tree.

dtourolleandClaude Opus 5 d91f1ec277 Thumbnail the whole library on request, and send the shards up
The grid fetches a preview only for cells that are actually browsed, which is
the right posture over a link that must not be saturated to show one screen
(FR-NC-3). The cost is that the thumbnail store ends up holding the fraction of
the library someone happened to scroll past — and that store is the one derived
thing worth syncing, since a second device that downloads the shards gets a
full grid without touching a single RAW. So the complete set is worth an hour
of range fetches paid once, deliberately, on a machine that can afford it.

That is what this adds: a pass over every visible image with an `oc:fileid`,
launched from the settings page and reported in the activity register like
every other background job. The work list is what the store lacks rather than a
flag in the catalog, so it is resumable by construction and safe to press
twice.

Lane-parallel like the metadata sweep, but it does what that sweep declined to.
The store is `&mut` and cannot cross lanes, which is why dating the library
skips thumbnails entirely; here the lanes fetch, decode and *encode*, and only
the ~20 KB result crosses back to the one thread that owns the store and writes
the chunk. The parallelism is real and the single-writer rule is not bent.

Grid class only. The large class is ~860 MB of shards against ~200 MB on the
reference library, paid by every device that syncs them; a photograph looked at
closely still gets its large thumbnail from the interactive path.

Dates come free — the header a preview needs is the header EXIF lives in — and
the pass ends by pushing the shards to the server. A filled store that never
leaves this device would be most of the cost for none of the point.

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 c36d4c80c8 Give the calendar one reading of a capture instant
The era-based conversion sat in library_ui.rs with two readers: the
timeline's month headings and, through format_date, the exporter's {date}
token. Import folder templates are a third, and three copies of a date
calculation that could drift apart is one too many — an image filed under a
date the timeline does not show it on is a file the user cannot find.

Moved to dr_types::time, which is where shared vocabulary lives, and given
the offset-aware reading an import needs: a shot taken at 23:30 in Tokyo
belongs in Tokyo's day, and filing by UTC would split one night's
photographs across two folders at whatever hour the offset happens to be.

dtourolle caf61d41a5 Re-thumbnail a photograph from its own edit
A thumbnail comes from the file's embedded preview, which is the camera's
idea of the photograph and knows nothing about what has been done to it
since. So a frame could be cropped, turned upright and pulled two stops
back, and the grid would go on showing the original — making the library,
where a photographer spends most of their time, the one view in which an
edit is invisible.

The render is the framed output, not the sensor: `output_size` is what a
crop, a quarter turn, a flip and a straighten all act on, so a thumbnail
taken from the raw frame would be the right pixels in the wrong shape and
still the wrong way up. It is the same path an export takes, at a size
the store wants rather than at full resolution, and always sRGB — this is
a JPEG in a shard that syncs between devices and is drawn as a cell, not
a file anyone is finishing.

Both size classes are replaced. The store keys on the class, so
refreshing only the one the grid happens to be drawing leaves the other
holding the unedited preview, and a zoom across the boundary would show
the edit undoing itself. Each is rendered rather than downscaled from the
larger, which would be a second and worse resampler than the GPU has
already applied.

It runs on the way out of develop, after the sidecar write is queued and
never instead of it — the edit is what must not be lost, and a render
that failed must not take the save down with it. Two cases are worth the
work: an edit made in this sitting, which `can-undo` records even when it
ends back at neutral, and an image opened with an edit already in its
sidecar and left untouched, whose cached thumbnail has never shown that
edit at all. A neutral image nobody touched fails both and costs nothing.

Not covered: a batch paste onto a selection, which deliberately never
opens a session — there is no rendered frame to take a thumbnail from,
and downloading forty RAWs to make forty is exactly what that path exists
to avoid.

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.

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.

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.

dtourolle d2c909414c Stop zooming rebuilding the grid twice a frame
A pinch is not one zoom step, it is a stream of them, and every step
changes both the column count and the capacity — two reports. Each report
re-queried the catalog, rebuilt all 360 rows of the model, re-read the
badges and ratings for every one of them and spawned a thumbnail batch,
synchronously, on the thread trying to draw the frame. Twice per step.
That is why zooming juddered while scrolling the same grid is smooth: a
scroll reloads a few times per screenful, a zoom reloaded twice a frame.

None of that work is urgent, because none of it is about which
photographs are on screen. The window holds the same images however they
are laid out — the model already has them, and the cells re-flow from
`columns` and `cell-size` with Rust not involved at all. What the reload
actually recomputes is which cells begin a row, so the month headings
land correctly, and which thumbnail size class to ask for now. Both can
wait for the gesture to finish, so both are now coalesced behind a single
settle timer: replacing the timer drops the previous one, and only the
last report of a run lives long enough to fire.

The anchor is captured on the first report of a run rather than read when
the timer fires. As the grid re-flows the viewport keeps its pixel offset
while the rows move underneath it, so the view drifts and reports the
drift; reading the anchor at the end would faithfully return to wherever
it had wandered. Taking it at the start returns to the photograph the
user was looking at when they started the gesture.

dtourolle 1980fda737 Show the library on launch instead of scanning first
A launch does not have to discover the library. The catalog from the last
run is on disk, complete, with its thumbnails in the shards beside it —
exactly the state offline mode already leans on when the server cannot be
reached.

Every launch that *could* reach the server threw that away. The catalog
handle was only opened when the scan reported Done, so the grid sat on
"Scanning…" over an empty EmptyState for as long as a recursive WebDAV
walk of the whole tree takes. On a real library that walk is essentially
the whole startup time, and it was spent hiding a grid that was ready
before it began.

The catalog is now opened and the first window loaded before the scan
thread is spawned — before, so the schema migration cannot race the
worker opening the same file, and so the first thumbnail batch is already
in flight while the walk runs. The scan still replaces all of it the
moment it lands; it just no longer gates the first paint on the network.

A first run has nothing to open, which stays silent: `Catalog::open`
creates the file, the grid reads an empty catalog, and the empty state
goes on saying "Scanning…" — which is true, and which an error here would
contradict.

dtourolle 80f1a210cc Keep the view pointing at the same photograph when the columns change
Two faults behind "the gallery randomly glitches to blank and needs a
scroll to reset it", and behind the scrolling that skips.

Cells are drawn at their absolute place in the library, so the row a
photograph sits on is `index / columns`. When `columns` changes every
cell moves — and the Flickable's `viewport-y` did not move with them. The
view was left pointing at a row that now holds entirely different
photographs, typically thousands of images from the ones the loaded
window covers, so the grid drew nothing at all. It stayed that way until
a scroll reported a first-visible row and dragged the window back under
the view, which is exactly the reset the user found. None of its triggers
are rare: a resize, the collections sidebar opening, a zoom step, or
turning the tablet over.

The last first-visible ordinal names the photograph being looked at, so
it is now sent back through `scroll-to` and the view lands on that same
photograph at whatever row it now occupies.

The second fault is the window-move test. At either end of a scope the
window is pinned — the first screenful cannot be centred further back
than zero, the last cannot start past the last full screenful — so the
margin test was unsatisfiable there and every row crossed in the first or
last quarter of a window re-read the catalog, rebuilt the model and
issued a thumbnail batch to arrive at the offset it already held. On a
library of twenty-odd thousand that is a stutter at the top and the
bottom of every collection, which is where a cull begins and ends.

The decision is now a rule with tests rather than four lines inside the
scroll handler: both of its ways of being wrong are invisible in the code
and obvious on a tablet.
2026-08-21 20:34:01 +02:00
dtourolle deabac0923 Carry a photograph's thumbnail across a reload
Work in progress found uncommitted in the tree, committed as its own
change so the fixes that follow can be read separately. Not authored in
this session; the description below is written from the diff.

`load_window` rebuilds every row, and a scroll reloads once the view has
travelled a quarter of the loaded window — so three quarters of the cells
being rebuilt are the same photographs already on screen. Rebuilding them
empty blanked the grid to `Theme.ground` and refilled it a beat later,
once a worker had re-read and re-decoded each one from the store. That is
the black flash on every screenful of scrolling, and on a column change,
a zoom step, a filter and a return from develop.

Thumbnails are now held by `image_id` across the swap — a refcount per
cell, no pixels move — along with the "no preview" verdict, which is an
answer about the file worth keeping for the same reason. `requested` is
rebuilt from what the new model actually holds rather than cleared, so a
carried cell is not fetched again while one newly scrolled in still is.
The size class each cell's pixels came from is tracked alongside, so a
grid zoomed past that class still asks for the sharper one.

Also guards the whole `scrolled` and `columns-changed` handlers on
`show-library` rather than just the resume latch: a Flickable being torn
down passes its viewport through zero, which was indistinguishable from a
fling to the top and reloaded the window against the first rows of the
catalog every time an image was opened.

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 d2d5d6f22b Keep the selection visible when the grid scrolls under it
Scrolling rebuilds every cell, and a fresh cell carries `selected: false`.
`sync_badges` and `sync_ratings` refilled what the rebuild cleared;
nothing refilled the selection, so the ticks vanished on every scroll.

The selection itself was never lost — it is a set of image ids and
survives untouched — which made this worse than losing it: the header
buttons still acted on forty photographs the user could no longer see
were held.

`load_window` reaches the selection through a `Weak` handle set at
wiring. Weak because the two controllers are joined only through the
window, and an `Rc` each way would leak both; absent, the grid draws
nothing selected, which is what it did before.

The timeline counted the whole library whatever the grid was showing, so
opening a collection left a fortnight in Arosa as one column of a
fifteen-year axis — an axis describing photographs that were not on
screen.

Scope the buckets and the span to the same collection and rating filter
the grid uses. `timeline_range` counts `images` alone and cannot express
the membership join, so the scoped query lives beside the other scoped
readers in the UI and shares their descendants-of-scope rule.

`catalog_span` now delegates to the same scoped reader. Zoom and scrub
measured the full library while the bars were scoped, so a scrub could
land on an instant the collection did not contain and send the view
somewhere the user had not asked to go.

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 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 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 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.

A cull is thousands of decisions. The grid already bound 0-5, P, X and U so
the judgement itself needs no mouse, and then made the photographer reach
for one to move to the next frame — which is most of the gesture, most of
the time. Arrows now move a cursor, shift+arrow extends the selection,
Home/End and PageUp/PageDown cover ground, and Return opens what the cursor
is on.

The cursor is a library ordinal, not a row of the loaded window. The window
is a few screenfuls around wherever the user is looking, so a cursor held as
a row would stop at its edge or keep counting into cells belonging to other
photographs; walking out of the window reloads it around the new position,
exactly as scrolling does. This is the argument the selection already made
by keying on ids rather than rows.

The anchor had that fault for real: it was a window row, so a shift-click
after a scroll extended from whatever image had since drifted into it. It is
an ordinal now, and apply_press takes the window's offset to map between the
two. A range longer than the loaded window truncates to what is loaded,
since selection is by id and an image the catalog has not been asked for has
none.

The pointer and the keyboard share select_row so the two cannot drift apart.
The one deliberate difference: a plain arrow collapses the selection onto
the cursor, where a plain click on an already-selected cell leaves it alone
— that exception exists so a multi-image drag can start from one of its
members, and there is no drag behind a keystroke.

The grid scrolls to the cursor only when the cursor leaves the viewport, and
then by as little as will do it. Reusing the scrub's seek() would put the
cursor's row at the top on every press, which makes a row unreadable as you
walk along it.

The Android job's "Verify minimum API level" step has never verified the
minimum API level. It took the first `*.so` anywhere under the target
directory, which is a host proc-macro from debug/deps — an x86-64 object
built by the runner's gcc, whose .comment section cannot mention Android
and so can never contradict the expected value. It now reads the artifact
under the target triple, compares against MIN_API parsed from the
Dockerfile rather than a second copy of the number, and fails on a
mismatch. Both sides are checked non-empty first: two failed parses would
otherwise compare equal and pass, which is the same silent success in a
new costume.

The Android image installs one SDK package per layer and keeps the
output. sdkmanager is a JVM program that aborts when it cannot get memory,
and the single `> /dev/null` step reported that as a bare "exit code 134"
while a retry re-downloaded everything that had already succeeded.

tools/ci-local.sh runs all four jobs — desktop, android, layering,
traceability — against the host toolchain, which is pinned to the same
1.92.0 CI installs. Its matrix check compares regeneration against the
working tree rather than against HEAD: CI starts from a clean checkout, so
git's answer is the right one there and reports every local run stale here.

The rest is rustfmt across the workspace, and the clippy findings that
surfaced once it did: manual_contains in dr-thumbs and collections_ui, a
map iterated as pairs for its keys, an index loop over a slice, and two
runtime assertions on a constant now made at compile time.

Fills in `image_cache`, which the previous commit's "On this device" filter
read but nothing wrote. Also carries in-flight work that shared these files:
the Android TLS root store, the settings page, and a regenerated
traceability report.

# Two populations, deliberately separate

An original is kept here for one of two reasons, and conflating them produces
the exact failure the feature exists to prevent.

**Pinned** originals were asked for. Pinning a collection before a trip is a
promise, so pinned rows are never evicted and never counted against the
budget — a cap that could silently delete a pinned trip would make pinning
worthless, because it could not be relied on without checking.

**Passively cached** originals are a side effect of working: develop already
downloads the whole file, so keeping it costs no bandwidth and saves the
entire transfer next time. This population is what the budget bounds, evicted
least-recently-used, because it otherwise grows until a day of culling fills
a disk.

Sharing one budget would let a large pin starve the passive cache, or let
browsing evict a pin. They are separate.

# What was built

`dr_catalog::cache` owns the bookkeeping — held tier, size, last use, pinned
— and writes the bytes; deciding to download stays with the caller, which is
what keeps a crate with no network out of the network's business. Files are
written to a temporary and renamed, so a dropped connection cannot leave a
truncated file recorded as a complete original. They are named by image id,
not filename: `Photos/IMG_0001.CR2` and `Trips/IMG_0001.CR2` are different
photographs, and a flat cache keyed on the name would serve one for the other.

`spawn_full_fetch` became read-through. A hit is a disk read; a miss stores
what it downloads and enforces the budget. A cache that cannot be opened is a
miss, not a failure to open the photograph.

Pinning writes intent — `tier_desired` — without downloading, so the button
responds immediately, and `spawn_pin_fetch` fills it in sequentially
afterwards. Sequential because these are tens of megabytes each: the lanes
that make the thumbnail sweep fast buy little against one connection's
bandwidth and cost a great deal of memory. A pin interrupted by a lost
connection resumes from where it stopped.

Schema v5 adds `pinned` and `path`. `pinned` is a column rather than something
inferred from `pinned_by_rule`, which is ON DELETE SET NULL and so cannot
answer for an image whose rule was deleted. A v4 catalog migrates in place;
existing rows default to unpinned, the safe direction.

The budget and "keep opened originals" come from the settings page rather than
a constant, and are applied at startup rather than only on change — a cache
capped at 2 GB last session would otherwise spend this one filling to the
default. Turning off keeping leaves what is already cached readable: those
bytes are paid for, and refusing them would re-download images sitting right
there, including pinned ones.

Also removes a doubled `#[test]` introduced in the previous commit.

dtourolleandClaude Opus 5 cd75e5a4c6 Run the library from local data when the server is unreachable
Also carries in-flight work that shared these files: the zoom structure-key
fix in the adjust pipeline, nearest-neighbour filtering past 1:1, the
timeline scrub marker correction, the 423-Locked retry in the metadata
sweep, and the thumbnail size-class migration.

# Offline mode (FR-CAT-9)

The app previously assumed the server was reachable and treated its absence
as a series of unrelated per-operation failures. A launch without a
connection produced an empty grid, even with a complete catalog on disk and
every thumbnail already in the shards.

Reachability is now inferred from traffic the app was already making, rather
than probed for. `RemoteError::indicates_offline` draws the line that makes
this possible: a dead connection is offline, a 403 or a 500 is not — the
server answered, so blanking the library over one forbidden file would be a
worse error than the one being reported. `Reachability` turns those outcomes
into a state, so a library browsing happily never issues a probe at all.

Going offline takes one failure, because the user is already experiencing it.
Coming back requires evidence — a completed scan or a fetched thumbnail —
with a capped exponential backoff behind the manual retry, so twelve sweep
lanes failing together do not schedule twelve immediate probes.

What keeps working: the catalog opens even when the scan that normally
provides it failed, so the grid fills from the last successful scan.
Thumbnails come from the shards. Rating, flagging and collecting are catalog
writes that never touched the network. What stops is opening an original that
was never stored locally, and it now says so in those words instead of
reporting "network error: connection refused" over a photograph.

Work that is pure network is refused rather than left to fail slowly: the
metadata sweep, derived sync, and sidecar writes. The sweep would otherwise
spend a timeout per image across the whole library while the progress bar
implied something was happening. Deferring sidecars is a real gap rather than
a hidden one — a rating made offline reaches its sidecar only when that image
is judged again while connected — and it is recorded as such at the call site.

# The "On this device" filter

A chip beside the rating filters, narrowing the grid to images whose original
is held locally. It composes with the rating terms rather than replacing them,
so "five-star frames I can actually edit on this train" is one filter. The
predicate is SQL, like the rating terms and for the same reason: the count in
the header has to agree with the cells drawn.

It reads `image_cache.tier_actual`, which nothing writes yet — the next
commit fills it. Until then the chip honestly reports zero.

`Tier` gains an explicit on-disk encoding. The variants are ordered by
generosity and the derived `Ord` invites reordering them, which would
silently reinterpret every cached row; the round-trip test is what holds the
two in agreement.

The marker was drawn from a bucket index while a click reported a
fraction of the track. Those are different quantities: bars each occupy
one equal slot whatever span of time they cover, and the index snapped
to the containing bucket's start edge, so the marker landed at the top
of whichever slot held the instant — close enough to pass on a dense
uniform axis, plainly wrong on a sparse one, and never under the click.

Send the fraction instead, computed as the exact inverse of the
interpolation the scrub handler applies, and position the marker from
it. Marker and click are now the same quantity by construction.

Scrolling the grid also left the marker behind: only an explicit scrub
ever wrote the position, so the axis claimed to say "when you are" and
stopped being true the moment the wheel moved. Map the first visible row
back to a capture time and move the marker with it.

That runs on every scroll event rather than behind the window-reload
guard, which fires a few times per screenful and would make the marker
advance in jerks. Only the marker moves, not the bars: rebuilding those
means a GROUP BY aggregate over the library, far too much for a flick,
and they do not change as the grid scrolls anyway.

dtourolleandClaude Opus 5 d49b4b41de Add thumbnail size classes and grid zoom; fix the scrub ordinal
The grid now zooms, which needs thumbnails at two resolutions rather than
one, and exposed a scrub that landed in the wrong place.

**Two thumbnail size classes.** `ThumbSize::Grid` (256px, ~10 KB) and
`Large` (1024px, ~45 KB), with the class part of the store key so both
coexist. Storing everything large would take the reference library from
~200 MB to ~860 MB, and shards sync, so that is transfer cost on every
device rather than only disk. A store written before the class existed
migrates in place: its entries are all grid-sized, which is what the
column defaults to, so nothing already fetched is discarded.

`forget` now drops every size for an image. Reading a single row left the
other class's bytes on the shard's tally for good, sealing it early on
space nothing occupied.

**Grid zoom.** Ctrl+wheel and pinch resize cells between 90px and 420px in
geometric steps, so the gesture feels the same at either end where a fixed
pixel step would be imperceptible at 400px and violent at 90px. Crossing
256px switches to the large class, so a zoomed cell is sharp rather than
upscaled. Columns and window capacity already derived from cell size, so
the grid reflows for free.

**The scrub landed about half a library too high.** It counted only dated
images while the grid shows all of them — 10,733 dated against 19,841
rows — and ignored `shadowed_by`. Verified against the live catalog: the
old formula gave 10,887, the new one 10,732, the true grid position
10,732. The scrub's count and the grid's window must use identical
predicates and ordering; a test now fails if they diverge.

**Timeline gestures are continuous.** Scrub and pan were quantised to
whole buckets, so a slow drag did nothing until it crossed a boundary and
then jumped a month. Both work in fractions of the visible span now, and
pinch-to-zoom arrives for tablet, where there is no wheel to reach the
axis with.

The pinch accumulator was wrong on first writing: it took at most one step
per update, so an 8x spread — three doublings — yielded one zoom level.
`log2().trunc()` now extracts every whole doubling and carries the
remainder. The original test asserted the wrong number and defended it in
a comment, which is worth remembering: a test can entrench a bug as
readily as catch one.

dtourolle 8ad5c86ff9 Add the library, collections, and trash views; theme from style.yaml
The UI gains the views the catalog work was building toward: a windowed
library grid with ratings and flags, the collection tree with drag-to-add,
and trash with restore. derived_sync pushes thumbnail shards and the catalog
snapshot to the server's derived folder.

Tokens now have one source of truth. build.rs reads style.yaml and generates
theme.slint into OUT_DIR, which answers every existing
`import { Theme } from "theme.slint"` unchanged, because Slint resolves
imports against the importing file's directory first and the include paths
after. Generating into OUT_DIR rather than beside the hand-written Slint is
the point: a generated file sitting in ui/ looks exactly like the files
around it that are meant to be edited, and an edit to it would survive until
the next touch of style.yaml — a bug that hides for weeks. build.rs fails
loudly if a stale ui/theme.slint exists, which would otherwise shadow the
generated one silently and make every palette change vanish with no error.

The palette moves to near-neutral dark with achromatic signalling, so the
accent means "modified" or "active" rather than "heading". Shared components
land in widgets.slint: a token that binds several values into one concept is
a component, not a row in a YAML file.

Adds an optional live-style feature that makes the tokens in-out so they can
be written at startup — a feature rather than the default because it stops
the properties being constant-folded.

serde_norway is the YAML crate: serde_yaml and serde_yml are both deprecated,
and its mappings preserve insertion order, which is what lets the generated
Slint keep the token ordering the author chose.
