Zooming the develop view changed the exported file. `Framing::view` is
kept out of the sidecar, out of `is_active` and out of `output_size`
precisely so that it cannot — but those exclusions keep it out of the
*edit*, and an export is a *render*. `visible_rect` deliberately folds
the view into the single rect the fused shader's prologue samples, so
`render_for_export` inherited it: at 4:1 it wrote the middle of the
frame, magnified to fill the file at the full output size, with the
detail kernels scaled four times over because `render_scale` folds the
view in as well. `render_thumbnail` did the same to the grid.
`render_uncropped` already suspends the view for this exact reason, so
the fix is its pattern: one `render_the_file` that both file-producing
paths go through, composing inside the suspension since the view
reaches the shader as a uniform baked at composition time. Restored
whatever happens — leaving the graph un-zoomed after a failed export
would throw away where the photographer was looking.
Nothing caught it because the guard checked the wrong things.
`zooming_does_not_change_the_exported_image` asserted the output size
and the crop; both held perfectly throughout. Renamed to
`zooming_does_not_change_the_size_or_the_crop`, which is what it
tests, and the pixels are now guarded where pixels exist. The new test
uses a ramp rather than quadrants deliberately: a four-quadrant frame
is self-similar under a centred zoom, and the first version of this
test passed against the bug because of it.
Traces FR-EXP-9, which asks for the full-quality pipeline "regardless
of what the display was showing".

Everything argued for this change so far was read out of a catalog
after the fact: crop_px across 18,671 faces the old code had already
stored. That is evidence about what the previous implementation did. It
is not evidence that the new one does better, and the difference matters
because a landmark left in the detector's coordinates, or a box filter
with an off-by-one in its source span, would both produce faces that
look entirely plausible until somebody counted the pixels behind them.
So examples/face_native.rs renders one file and indexes it twice, native
and from a 1024 proxy, changing nothing else. Fourteen originals from
the reference library, 5472x3648 CR2 and DNG:
native 9 faces, mean crop 287px
1024 proxy 5 faces, mean crop 75px
Crops 3.8x larger, and across the line that decides whether the crop is
photographed or interpolated: 75px is below ALIGNED_EDGE, so the proxy
path was upsampling into the embedder on average where this one
downsamples into it. Fourteen images and nine faces is enough to show a
direction and to catch a wrong scaling; §7b says so rather than quoting
the ratio as a library-wide figure.
It also corrects something §7b asserted two commits ago. I wrote that
detector input resolution cannot affect recall, because §4.1 letterboxes
everything to 640. Native found nine faces to the proxy's five,
including four on files where the proxy found none, so it plainly can.
The two paths differ in their resampling as well as their size, and this
experiment does not separate those, so §7b now records the result as
evidence for the double-resampling hypothesis rather than as its proof.
M4 still owns settling it.
The audit-summary test went stale when the ready/to-fetch split was
collapsed and is updated to assert the single number, including that the
old wording is gone.

Implements the FR-CULL-8 written two commits ago. The sweep fetched the
JPEG preview embedded in each RAW and used that one buffer for both
detection and the crop; it now fetches the original, renders it through
the same path export uses, reduces that for the detector, and warps the
crop back out of the native frame.
Three pieces, and each exists for a reason worth stating.
dr_face::Pixels lets the warp sample 8-bit RGBA directly. A 24 MP native
frame is 96 MB as RGBA and 288 MB converted to the f32 RGB align.rs was
written against, and the warp reads about forty thousand pixels out of
it. Converting the whole frame to sample 0.2% of it is NFR-RES-2's
budget spent on a copy, per image, for a whole library. The variant
costs one branch per sample and a test asserts both layouts produce
identical crops.
The detector gets a box-filtered reduction to 1600px, not the native
frame and not a point-sampled one. Averaging rather than sampling
because the detector's job is finding small faces and decimation is
precisely the operation that removes them: at 4x, fifteen of every
sixteen pixels are discarded and a 40px face survives or not depending
on where it falls relative to the sample grid. 1600 rather than 640
leaves the letterbox a mild 2.5x rather than a 9x, and bounds the f32
buffer at 20 MB.
Landmarks come back in the reduction's coordinates and are scaled to
native in one place before any crop pixel is read. This is the failure
mode that would not announce itself -- unscaled landmarks put every crop
near the top-left corner, which yields faces of something else, cleanly
embedded and confidently clustered.
The sweep fetches SWEEP_LANES-wide and renders sequentially. Not a
placeholder for a parallel version: there is one GPU, so concurrent
renders queue on it regardless, and each materialises a native frame.
Overlapping them would multiply the one allocation that threatens the
memory budget while buying parallelism that does not exist. The chunk
drops from 96 to 6 for the same reason -- 96 held 8 MB previews, this
holds whole RAWs.
The stored edit is deliberately not applied, which is where this departs
from export::render_from_library. Face geometry is normalised to the
frame, so indexing a cropped render would record boxes against a frame
that changes whenever the user changes their mind, and every stored box
would quietly become wrong. Orientation is applied: that is a fact about
the file rather than an edit.
examples/face_native.rs renders one file and indexes it both ways, so
the claim behind all of this can be checked against photographs rather
than re-read out of the catalog it came from.

FR-CULL-8 said detection runs against the thumbnail or proxy tier and
never a full decode, and faces.md §5 said the aligned crop is sampled
from that same proxy. Both are wrong in the same place: they treat
detection and cropping as one resolution problem when they are two, with
opposite answers.
Detection does not care. §4.1 fixes the graph's input at 640x640 and
letterboxes whatever arrives, so a face filling 2% of the frame reaches
the model at 12px whether the buffer handed over is 1024px or 6000px.
Every pixel above the detector's own input is discarded before inference.
The crop cares about nothing else. §5's warp produces the fixed 112x112
ArcFace sees, so source resolution converts directly into whether those
112 pixels were photographed or interpolated. Reading crop_px across the
18,671 faces the proxy-tier implementation stored: 47.3% were upsampled
to reach the embedder, 314 of them by more than 2x, the smallest from 34
source pixels. An upsampled crop does not fail loudly -- it yields a
confident embedding of detail that was never there, and the damage
appears three stages later as clusters that will not separate.
So FR-CULL-8 now specifies four stages with the resolutions named
separately: render native through FR-EXP-9's pipeline, downscale for the
detector, map boxes and landmarks back to native, crop and align from
the native render. The affordability the old rule bought is met instead
by when the pass runs -- background, preempted, resumable -- and the
requirement says plainly what it now costs on a remote library: the
original rather than FR-NC-3's byte range, 412 GB across the reference
library's 19,107 images, so a whole-library pass is a transfer under
FR-NC-6 rather than something that may start on its own.
MIN_CROP_EDGE replaces the MIN_DETECT_EDGE this branch briefly had. Same
number, guarding the quantity that turned out to matter.
faces.md §7b records both measurements, and marks the second as
unexplained rather than dressing it as a finding. Grouped by the buffer
detection ran against, faces per image was 0.078 at 1024 or below and
1.82 at 2048 or better, controlled for file type and size. That gap is
real and reproducible and I cannot account for it, because the letterbox
above says detector input should not matter. M4 is where it gets
settled. The crop measurement does not depend on it.

Reverts 53f7cdf and e92d22d. The floor those added sat on
Detector::detect, refusing any buffer under 1025px on the reasoning that
a small buffer finds no faces. That reasoning does not survive §4.1:
the detector letterboxes every input to 640x640, so a face occupying 2%
of the frame presents at 12px to the model whether it is handed a 1024px
buffer or a 6000px one. Detector input is precisely the quantity that
does not matter.
Worse than merely useless, it blocks the design FR-CULL-8 now specifies,
where the detector is deliberately fed a downscale and the crop is taken
from the native render. A guard on detect() rejects exactly that call.
What the measurement actually supports is a floor on the *crop* source,
which is where resolution converts into embedding quality, and which
faces.crop_px already records: 47% of the reference library's faces were
upsampled to reach 112x112. That floor is a separate change against the
native-resolution path and does not belong on the detector.
The 23x faces-per-image gap by source_edge that motivated the original
commit is kept in faces.md §7b, restated as the unexplained observation
it is rather than the causal claim it was written as. V12 stands: those
runs cropped at 1024 whatever detection did, and that is reason enough
to look at them again.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The floor introduces a state the sweep had no arm for. An image whose
largest embedded preview is genuinely smaller than 1025px now comes back
from index_preview as an error, lands in the generic Err arm, and is
counted as failed -- which means no face_index row, which means it is
still outstanding, which means the next sweep fetches exactly the same
bytes and refuses them again. For ever, on every run, at one range
request each. The previous behaviour was wrong but at least terminated;
this would not.
So ProxyTooSmall gets its own arm, and it records a marker at the true
edge rather than nothing. That is the difference between "we looked and
found nothing" -- which would be a lie, since nothing was looked at --
and "this was examined at 900px, which is the best this file has". The
first is unrecoverable; the second is a fact source_edge was added to
carry, and a later floor or a bigger proxy can select on it deliberately
the way V12 just did.
Counted separately from failures all the way up, because they are not
failures and reading them as such would misdescribe a library of small
scans as a broken network. The summary line says how many and why.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The floor added in the previous commit stops this happening again; it
does nothing about the 1,824 images in the reference library that
already carry a face_index row written against a proxy of 1024 or less.
Those rows are why the damage is permanent rather than merely past. The
work list is "images with no row for this model", so an image examined
against a 1024px proxy -- 0.078 faces per image, nine in ten finding
nothing -- is indistinguishable from one examined properly, and no
later pass will ever offer it to the detector again.
V12 deletes exactly those markers, and nothing else. The faces those
runs did find stay in place and keep drawing the People screen until a
better pass replaces them, and record_detections re-attaches the user's
confirmed names across that replacement by box overlap, so a library
somebody has spent an evening naming does not lose that evening. The
cost is a re-fetch of the affected images.
Deleting the marker rather than teaching the work-list query to select
on source_edge, which was the other option and is worse. A standing
`source_edge < floor` predicate never lets go: an image whose largest
embedded preview is genuinely smaller than the floor would be re-fetched
on every sweep for ever, because the next pass cannot do any better than
the last one did. A one-off deletion gives each affected image exactly
one more attempt through the good path and then lets the ordinary
"has a row" rule settle it.
The threshold is written out in the SQL instead of referring to
dr_face::MIN_DETECT_EDGE. A migration has to keep meaning what it meant
when it ran; binding it to a constant someone may raise later would
quietly change what an old catalog gets migrated to.

The refinement worked and could not be controlled. Pruning modes below a
share threshold made the flag's removal a *discrete* event: below the line
its Mahalanobis distance was enormous and nothing rescued it, above the line
it sat at zero and nothing removed it. A control over that would appear dead
through most of its travel and then start eating sky.
So the prune is gone. A mode is charged `−ln(share × k)` nats, floored at
zero, and that cost enters both tests — doubled in the chi-square, which is a
squared distance, and directly in the log density. Rarity becomes a distance
rather than a threshold, and the things a photographer wants to remove
separate along it.
Measured on the synthetic frame the tests build: a flag holding 1.6% of the
sky is more than half gone by **2.95 nats** and a cloud bank holding a third
of it survives to **5.75**. The whole interval between them is somewhere a
control can sit. `the_flag_goes_before_the_cloud_does` pins the ordering,
which is the property that makes one slider worth offering at all.
Measured against an even split rather than against one, so raising
`clusters` describes a category more finely without making every colour in it
look rarer. Floored at zero so a dominant mode earns no *discount* — a
bonus there would let the commonest colour outvote a bad chi-square, which is
the one direction this must not bend.
`Refinement` holds the per-pixel verdict, quantised to a byte over ±16 nats —
an eighth of a nat per step, far finer than the narrowest transition the gate
can be asked for, and the same size as the coverage buffer it sits beside.
`apply` is then a smoothstep, and the model is never consulted again.
That is `distance.rs`'s arrangement deliberately: there a signed distance
field is computed once and feather, grow and shrink become arithmetic on it,
"which is what makes those live controls rather than ones that stall on every
drag". Same shape, different field.
The blur moved with it, from the gate to the verdict. Smoothing the evidence
rather than the decision means it is paid for once in `compute` instead of on
every frame of a drag, and it is the better thing to smooth in any case.
`apply` at `STRICTNESS_OFF` returns the weights untouched without reading the
verdict at all. A control whose off position is *very nearly* the unrefined
mask cannot answer "is this helping"; one whose off position is the unrefined
mask can. `strictness_zero_changes_nothing` holds it to that, and
`strictness_is_monotonic` holds the rest of the travel to only ever removing
more — a slider that gave weight back partway up would be one whose direction
nobody could predict.
The synthetic sky is smooth enough to sit on `VARIANCE_FLOOR`, where a real
one has noise and therefore a real spread, which moves every crossing down
together. The ordering survives that; the placement is a calibration. Which
is the honest argument for a control rather than a constant, and why the
default sits at half scale instead of at the flag's measured crossing.
The example sweeps the whole range and writes a frame per nat, because the
question a photographer asks of a slider is where to put it, and that needs
the travel rather than a point on it.

A flag in the sky came out weighted as sky, and no feather setting fixed it.
The scene model's logits are `[1, 150, 80, 80]`, so one cell is eight input
pixels; at the 1600px proxy the letterbox scale is 0.4 and **one cell is 20
proxy pixels**, which `rasterise`'s bilinear then spreads across one more
either side. A flag is a handful of cells whose softmax is dominated by the
sky around it. The information was never in the grid, so nothing downstream
of the grid can recover it.
Tiling is the answer for an instance and is not available here: a category
has no bounding box to tile over — sky is wherever the sky is. But the
photograph is at full proxy resolution even though the weights are not, and
it knows exactly where the flag is. So the model says *what*, and the
pixels say *which of them*, which is the division of labour arm C already
draws between the instance model and the watershed.
## Seeds, and why the erosion radius is not a guess
Threshold the weights high, take `signed_distance`, and keep what is more
than 1.5 cells inside. One cell *is* the model's resolution and the bilinear
spreads it across one more, so the band either side of the boundary is smear
rather than evidence. Deriving the radius from `Scene::cell_pixels` rather
than picking a pixel count means it stays right if the proxy edge or the
export changes.
The mirror of that set is a confident *exterior*, free from the same field.
## Dropping small modes is the step that makes it work
Four k-means modes per side, not one Gaussian: sky is blue at the zenith,
white where the cloud is and pale at the horizon, and one blob over all
three rejects two of them.
Then modes holding under 3% of a side are discarded, and without that step
the whole thing fails on the case it was built for. A small flag deep in the
sky has both a high weight and a large distance from the boundary, so it
lands in the interior sample and teaches the model its own colour. It cannot
be excluded geometrically. It can be excluded by share.
Luminance is weighted at a quarter against chrominance for the same reason
the watershed's gradient is. Sky's variance is dominated by luminance, so at
equal weight the distribution is a long bright streak that a mid-grey flag
sits comfortably inside. A flag is separated by chrominance; a cloud is
separated by luminance alone. Not zero, or a dark bird against a bright sky
survives.
## Two tests, because either alone is wrong
Absolute — is this colour plausible under the category, as a chi-square on
the Mahalanobis distance. Comparative — is it likelier inside than outside.
A pixel must pass both.
The absolute test is what catches the flag, whose colour is far from *both*
sides and which the comparative test alone would leave at even odds. The
comparative test is what stops the absolute one needing a constant tuned per
category.
## What this cannot do, written down rather than left to be discovered
An intruder large enough to hold its own mode is kept. By share, a flag over
a fifth of the sky and a cloud bank over a fifth of the sky are the same
object, and colour does not separate them either — a white cloud is as far
from blue sky in chrominance as many intruders are.
So `min_cluster` is not a threshold with a correct value waiting to be
found; it is the trade-off itself, set where a photographic intruder falls.
Both ends are pinned by tests — `a_flag_in_the_sky_is_removed` and
`an_intruder_larger_than_min_cluster_survives` — so that moving the number
reads as moving the trade-off rather than as fixing a bug. The case left
open is a large unrecognised object in a clean category, which wants the
boundary snapped to watershed basins and is a different mechanism.
## Safe to apply without a control
It is subtractive: the output is the input times a factor in `0..=1`. The
worst failure available to it is losing part of a real sky, never gaining a
region, so a blue car below the horizon that was never in the mask cannot be
pulled into it. And a factor in `0..=1` cannot raise a sum, so `scene.rs`'s
partition still holds when every category is refined independently — the
weight taken off the flag lands in the unlisted remainder, which is where a
flag belongs, ADE20K having no class for one.
Every path without the evidence to judge returns the weights untouched and
says which path it took. A refinement that silently did nothing is
indistinguishable from the feature being off, and an empty seed set fitted
to a distribution would reject every pixel.
The signature is deliberately unchanged: categories are addressed by name,
not by index, so a sharper mask cannot create the stale-index hazard the
signature exists to guard against.
The example writes `<prefix>-<category>-refined.ppm` beside the coarse one,
never instead of it — whether this is an improvement is a comparative
judgement and one image cannot answer it.

The merge moved tagged lines in identity.rs, identity_ui.rs and the two
Slint files; the matrix tracks line numbers, so it goes stale on a move
alone. A merge commit does not run the pre-commit hook that would
normally have staged this.

`load_people` returned every live person, and on the reference library
that was 14,268 rows of which 11,739 held no faces at all — 85 per cent
of the rail naming nobody and able to do nothing.
They are not a mystery. A regrouping pass creates a person per cluster;
the next pass moves those faces elsewhere and leaves the person it
emptied behind. `faces::prune_empty_unnamed` exists for exactly this and
runs only at the end of a pass, so nothing clears what accumulates
between them, and the Identity screen never prunes at all.
Each one cost a `for_person` query and a built row on every reload. This
withholds precisely the set the prune already treats as disposable —
empty, unnamed, not set aside — and no more.
Filtered rather than deleted: a screen is being drawn, not a catalog
repaired. Nothing is lost, a sync cannot resurrect what was never
removed, and the prune stays the one place that decides these can go.
An empty group with a *name* still shows. That one is not debris but the
symptom of a real failure — a named person whose faces were regrouped out
from under them — and hiding it would take away the only way to merge
them back.

Three faults, all invisible in the source and all found by looking at
the window.
`alignment: start` on the selection bar. Slint only hands space to
`horizontal-stretch` children under the default `stretch` alignment;
under `start` every child takes its preferred width and the stretch is
ignored without complaint. That was harmless while the bar held four
controls. Now that it holds every selection verb it is the difference
between a count that gives way and a row that can only scroll, so the
alignment goes and the stretch does its job.
The title collapsed to "…". An eliding Text has a minimum of nothing,
so once the buttons had taken their own minimums the title was the
cheapest thing in the row to give away — the window stopped saying
which library was open while the byte counts beside it stayed. It gets
a 90px floor.
And the status line does not get one. After the sidebar takes its 232,
a 1100pt window leaves this header about 868, and the buttons want
most of that before a character is drawn — so something must degrade,
and the order is the whole question. A floor here bought a readable
status by pushing Settings off the right edge, reachable only by
knowing to flick-scroll, which is precisely the fault the row's own
Flickable comment warns about. A control you cannot see is worse than
a sentence you cannot finish. The status line is also the most
redundant thing in the header — the sidebar states the library's count
and the filter chips state it again — so it is what gives, and it
grows back the moment there is room.

Dragging a photograph out of the grid worked about half the time, and
nothing on the screen explained the other half.
`DragArea` and `Flickable` do arbitrate, but not evenly. The Flickable
claims any press that travels more than eight pixels along its own axis
within half a second of landing, and holds that claim until the finger
lifts. So a drag toward the sidebar only ever began two ways: a flick
sideways clean enough that the finger never wandered eight pixels
vertically, or a wait of half a second before moving at all. Both are
real gestures and neither was written down.
The wait is now the gesture, and it has a mark. The long press that
already turns on selection mode also picks the photograph up: a ring
opens around the cell and the grid stops scrolling under it, so from
that moment the drag is the only thing the finger can be doing. The cue
can only arrive after the ambiguity has passed, which is the right way
round — when the photograph lifts, dragging it works.
Two details worth naming. The hold is now armed even when selection mode
is already on; it used to be skipped there, on the grounds that there
was no mode left to switch on — but that is precisely the state a
forty-image drag starts from, so the one gesture that most needed a
pick-up was the one with none. And the ring is drawn after the cell
loop rather than on the cell: z-order inside a `for` is loop order, so a
cell grown past its bounds would stand over two neighbours and be cut
off by the other two.

"Keep offline" and "Change library" were buttons in the library
header, in a row that is otherwise entirely library-wide. Both refer
to the tree instead.
"Keep offline" could only ever mean the scoped collection, while
sitting nowhere near the tree that says which that is — and while the
sidebar already offered the same question twice, on each row's tray
and on a held row. It now sits under the tree, in the panel whose
selection decides what it acts on, in the same place and shape the
trash already gives Restore and Empty. It stays a labelled control
rather than being dropped for the tray: a 26px row's tray is a small
thing to hit, and "Kept offline" spelt out for the collection you are
looking at is the discoverable version.
"Change library" was wedged between Sync and Rescan, two buttons that
act on the library you already have. Reading it as one of that group
is a way to lose a scan by aiming badly. It is now the last thing in
the panel, under the tree it replaces wholesale, behind a rule.
On a tablet both are one tap further away, behind the sidebar toggle
that leads the header. That is the panel a user is already in when
they scope the grid to a collection, so it is where they are when
either of these becomes the thing they want.
The grid keeps `pin-done`/`pin-total` and its progress bar: the
transfer is worth reporting wherever it was started from, including a
row the grid is not scoped to.

The header carried four readouts beside the title: the image count,
the selection count, the scan's status and where in the library the
visible window sits. Each had `horizontal-stretch: 1`, which is what
actually lets a Text shrink in Slint — so between them they claimed
about a third of a 768px header and left the buttons to scroll off the
end of it.
The selection count goes to the bar at the foot of the grid, beside
the buttons that act on it. The other three are one subject and are
now one sentence with separators, sharing one stretch.
Two of them were also saying the same words while a sweep ran:
"indexing 300 / 12 480" appeared both as the status and, redundantly,
in place of the window position.

The selection bar had "Add to collection" and "New collection" side by
side. Both answer the same question — where do these go? — and the bar
asked it before showing the list that decides it: a user who wants a
collection they already have and a user who wants a new one press
different buttons before either has seen what exists.
"New collection…" moves into the filing sheet, under the list of
collections. That is where you look after failing to find the one you
wanted, and it is the only place the choice can be made informed.
It also fixes the sheet's empty state, which said "Make one with + in
the sidebar" — advice that cannot be followed on a tablet, where the
sidebar is instantiated but not drawn. The first collection can now be
made from the sheet that noticed there were none.

There was no benchmark harness of any kind -- no benches/, no criterion,
no synthetic fixture -- while §8 promised a suite run per commit that
fails the build on regression. Ten performance requirements could be
neither passed nor failed.
tools/bench builds a deterministic 50,000-row catalog over a pool of
twelve generated JPEGs, about 14 MB, reproducible from a seed, with a
stamp so it rebuilds rather than silently comparing against a different
workload. It depends on nothing GPU or UI, which is what makes the CI job
affordable.
NFR-P1 and NFR-P3 are gated and tagged. NFR-P7, NFR-P8 and R2 are
measured but deliberately untagged: the export gate is one-sided, the
memory figure is the catalog layer's share rather than the whole, and
R2's first sentence is a 60 fps scroll a catalog benchmark cannot claim.
Every recorded value in the baseline is null. Nobody has run this on the
reference desktop, and a fabricated figure would make every later
comparison a comparison against a guess.
First run on this machine: catalog opens in 70 ms against a 2 s budget,
and thumbnail throughput measures 37 img/s against a target of 100 --
reported rather than asserted here, and the first evidence that the
target may not hold.

"What can I do with these twelve photographs?" was answered in two
places. Six buttons in the header — Add to collection, Keywords,
Presets, Paste to N, Export N, Remove from collection — and four more
on the floating bar at the foot of the grid, beside the count that
says what they would act on.
The header half was the worse of the two. Those six appeared and
disappeared from the middle of the row as photographs were picked, so
Sync, Settings and everything beside them slid several hundred pixels
sideways at the exact moment a hand was already travelling toward one.
On a tablet the header scrolls sideways, so they were often not on
screen at all.
All six move to the bar. It now reads left to right as shaping the
selection — Clear, Select all, Select to… — then acting on it, with a
gap between the two thoughts. The header keeps only what belongs to
the library, and changes only when the library does.
Two consequences worth stating. The bar holds ten controls in the
worst case, so it scrolls sideways like every other row in this view,
for the reason set out on the header's Flickable: a layout given less
width than its children need overruns rather than shrinking, and the
buttons past the edge are simply gone. And the bar now stays up for a
running export whatever the selection has since become, because Cancel
export lived on a button that used to have its own `|| exporting`
escape hatch — the grid's viewport inset follows the same condition so
the last row of thumbnails is never trapped underneath.
`settings-summary` went with them: threaded from the window into the
grid and into HeaderActions, and never once drawn.

Five commits. `models/` becomes one tree at the repository root so the
weight the application carries is a single `du -sh`; the export script
stops building its multi-gigabyte venv in RAM; `yolo26s-sem-ade20k`
joins the instance model rather than replacing it; the decoder turns its
logits into a partition of unity over eight photographic categories; and
four packaging routes put the file somewhere each platform can find it.
The instance model stays exactly where it was. A semantic model merges
every pixel of a class into one region, so it cannot separate two people,
and separating two people is what clicking a subject needs. The scene tab
grades whole categories and does not care. docs/segmentation.md §16.

NFR-A11Y-2 went from five accessible-* declarations in the whole
interface -- all five on the colour mixer's swatch row -- to
seventy-three, on twelve shared components and four screens. The one that
mattered is SliderTrack: the most-used control in the application, until
now unnamed, and now carrying a label, a formatted readout and
increment/decrement/set-value, so it is adjustable rather than merely
readable. Fixing the shared components covered library.slint's
twenty-seven buttons and eleven chips without editing that file at all.
NFR-A11Y-1 is scaffolded and one screen of nine is converted -- 38 @tr()
calls, about a tenth of the interface's strings. Slint's translate()
returns the original when no bundle is active, so a converted string and
a literal behave identically today and each remaining screen is an
independent commit.
Two accessibility defects are recorded rather than fixed, as TD-6 and
TD-7 with measurements: ink-faint reaches 4.5:1 on no surface (3.97 at
best) and rule reaches 3:1 on none. Fixing either re-derives the palette
beside a photograph, which wants a screenshot and an opinion.
Verified: fmt, clippy -D warnings, 563 tests including a new integration
test that walks the markup and fails on an unnamed control.

`drag-payload` was documented as "called when a drag starts, so it
always reflects the selection as it is at that moment". Neither half is
true, and the comment is the only reason anyone would believe the drop
reads it.
`DragArea` tests `data.is_empty()` in its event filter — on every
pointer event, the first one included, which arrives long before there
is a drag. And a Slint binding that calls a callback has no dependency
to be invalidated on, so it is evaluated once, when a finger first lands
on that cell, and cached for the life of the cell. What it answers is
therefore always an empty selection.
None of the drop handlers read it; every one of them reads `dragging`,
which `drag-started` fills in at the moment that matters. What this
callback does is keep the `DragArea` armed, and it manages that only
because `set_user_data` is called unconditionally — an empty `Vec` is
still user data. Guarding that call, which reads as an obvious tidy-up,
would silently stop the grid dragging at all.
Comments only.

Dragging a selection of forty photographs onto a collection filed one.
Selection mode reports every press as a ctrl-press — deliberately, so
touch and pointer go through one set of rules rather than two — and ctrl
toggled. So the press that took hold of one of the forty took it *out*
of the selection on the way down. `drag-started` then looked at the cell
under the finger, found it unselected, and did exactly what it is meant
to do with an unselected cell: made it the whole selection and carried
it alone. The only sign was the grabbed cell's ring blinking out at the
moment the user began to move.
A plain press has never had this problem, because pressing an
already-selected cell has always been documented to leave the selection
alone — for precisely this reason. Ctrl now does the same: adding still
happens on the press, since the drag reads the selection immediately,
but *removing* is handed back as `Press::Deferred` and applied by the
click. Slint reports a click only for a press that stayed within
`tap-slop`, so a tap still toggles and a drag never does.
The unit tests now go through a `click` helper — a press and the release
that follows it — because that is the only thing a user can perform, and
calling `apply_press` alone would assert against half the policy.

The weights landed last commit with nothing to read them. This is the
decoder, and the shape of it follows from one property worth stating
before the code: the categories must partition the image.
## Why a partition, and not a mask per category
The scene tab applies one grade to every pixel of a category — lift the
sky, desaturate foliage — and both grades meet at the horizon. If each
category carried an independent mask, feathering them outward would make
the boundary band belong to both, so both grades would land there and
every horizon would acquire a visible seam. Feathering has to *blend*
there, not accumulate.
So `marginalise` takes one softmax over all 150 channels and sums within
each category. Grouping cannot change a total of one, so the listed
categories plus the unlisted remainder sum to one at every pixel, by
construction rather than by normalising afterwards. `parse_categories`
refuses a descriptor that claims a class twice, because that is the one
input that would quietly make the property untrue.
## The descriptor is data, and hand-written
`models/scene/categories.txt` groups ADE20K's 150 classes into the eight
a photographer would recognise. It is a file rather than a table in Rust
for the reason `models/LICENCE.md` predicted — a vocabulary is model
metadata — and it is line-oriented with comments rather than JSON like
the `.classes.json` beside it, because that file is generated and this
one is argued. Why `swimming pool` is water and not architecture belongs
next to the line that says so.
Classes are named, not indexed. An index is silently wrong after a
re-export; a name is loudly wrong, and the loader refuses one the model
does not have.
## Resolution, kept visible
`Scene` holds the native 80×80 logit grid and resamples on demand rather
than upsampling once at load. The coarseness is real — it is what the
graph produces — and a type that hides it behind an early resize invites
callers to expect detail that was never there. `rasterise` is where the
letterbox inverse lives, once.
`Letterbox` and `Window` become `pub(crate)` and `to_proto` generalises
to `to_grid`, because both dense outputs this crate reads are an even
fraction of the same letterboxed square and differ only in the divisor.
## Verified by looking, which is the only way this gets verified
`examples/scene.rs` writes the photograph dimmed outside each category. A
transposed axis or an off-by-one in the inverse produces perfectly
plausible weights over slightly the wrong pixels, and no unit test
catches that. On an indoor frame the person mask lands on the person,
including the outstretched arm, and sky reads ~5% against a bright
ceiling.
It doubles as the benchmark, because every timing quoted while this model
was chosen came off a laptop compiling other things and none of them
belong in a document.

docs/requirements.md §8 has said since it was written that performance is
verified by "an automated benchmark suite against a synthetic 50k catalog, run
per-commit … A regression beyond stated tolerance fails the build." There was
none. No benches/, no [[bench]], no criterion, no synthetic catalog, and three
CI workflows that between them measured nothing. Ten performance requirements
could therefore be neither passed nor failed, and five of them carried a
TRACES: tag regardless.
tools/bench is the half of that promise that can be kept honestly on a runner
with no GPU and no display.
# The fixture
Rows are cheap and pixels are not, so it builds fifty thousand catalog rows
over a pool of a dozen real files, each referenced by several thousand of them.
Everything the catalog half touches is rows and is exact at full scale;
everything the pixel half touches is one file at a time and does not care how
many rows point at it. Fourteen megabytes on disk instead of two terabytes, and
neither half is flattered by the trade. It is reproducible from a seed, and a
stamp beside it — seed, row count, source size, dr-catalog's schema version —
rebuilds it rather than letting a run be compared against a baseline that
describes a different library.
# What it can now pass or fail
NFR-P1, and R2's second sentence with it: Catalog::open plus the count, first
window and timeline the grid cannot paint without. The interesting part turned
out to be the open itself — schema::backfill runs three passes over the images
table on every open, which is O(library) work on a path whose budget is stated
in absolute seconds. Tagged TRACES: NFR-P1, on a gate that fails if it breaks.
NFR-P3: thumbnail throughput on the embedded preview path, through the same
per-image work spawn_thumbnail_sweep does and in the same shape — chunks of 96,
lanes owning disjoint slices, the single thread that owns the store writing the
finished chunk. Mirrored rather than called, because that function takes a
RemoteBackend and would measure somebody's network. Tagged TRACES: NFR-P3.
# What it deliberately does not claim
NFR-P7 is the whole chain, and only the encode half of it runs without an
adapter. So the export row is a one-sided gate — over two seconds in the encode
alone violates the requirement; under it proves nothing — and there is no
TRACES: NFR-P7 anywhere. NFR-P8 is about the application at idle, and the probe
is a process holding the catalog and nothing else, so it records the catalog
layer's share and carries no budget until somebody decides what that share
should be. No tag there either. CONTRIBUTING.md asks that a requirement be
closed by a test that would fail if the behaviour were removed, and two more
plumbing tags is what this repository already has too many of.
NFR-P8 also gets the answer §4.1 demands: RSS is exclusive of device-local GPU
allocations and cannot be made otherwise, because such an allocation never
enters the process's address space. The requirement should be restated as two
figures, and docs/benchmarks.md says so.
# Two gates, and why one of them steps aside off the reference desktop
The budget is the requirement's own number and never moves. The baseline is
what the reference desktop last measured, and drifting 15% past it fails the
build even while still inside the budget — which is how performance rot
actually arrives, never over the line, always a little worse.
A budget written for twenty-four threads cannot be asserted on a two-core
container. §8 names the reference desktop, not CI, so each metric declares
whether its budget is machine-sensitive; those are asserted under --reference
and reported everywhere else. Catalog open is not one of them: two seconds
against an expected figure two orders of magnitude smaller is a threshold any
machine can be held to. This is the trap core/dr-gpu/tests/frame_budget.rs
already refuses — a red gate everybody learns to ignore.
# The baseline ships with no numbers in it
Every recorded field is null, because nobody has run it yet. Writing
plausible-looking figures would make every later comparison a comparison
against a guess, and the first real regression would be invisible. Run
`dr-bench record --reference` on the reference desktop and commit the diff;
until then the budget gate works and the report says the other one cannot.
# CI
.gitea/workflows/benchmark.yml, and its own workflow rather than a step in
build-and-test.yml: a red "Build and test" says the code is wrong, a red
"Benchmarks" says it got slower, and the second must not be reachable by
retrying a flaky compile. The cpu job runs on every push and builds -p dr-bench
alone — which is why that crate depends on no GPU and no UI crate. The gpu job
is the frame budget that already exists and already skips without an adapter,
on workflow_dispatch, because building wgpu on every commit to rediscover that
the runner has no device is not a use of anybody's minutes.
`previous_anchor` existed for one gesture: a double tap in selection
mode took the range from where selecting began, and both taps had
already moved the anchor onto the cell being tapped, so the origin the
user meant had to be remembered separately.
That gesture is gone — "Select to…" says what it is about to do instead
of hiding a forty-image range behind a thing a hand does by accident —
and what is left is a field that four places write, `PressUndo` carries,
`cancel_press` restores, and nothing at all reads. `apply_press` is
`select_row`'s only call now that there is no anchor to remember, so the
wrapper goes with it.

A cell drew a 1px ring while the pointer was over it, in the same colour
as the 2px ring that means "selected". On a tablet there is no pointer,
and `has-hover` is not the harmless no-op that implies: Slint raises it
on a touch press and lowers it on the `Exit` that normally follows the
release — but the release that ends a pinch carries no `Exit` at all,
and neither does a finger lifting while a second one is still down.
So resizing the thumbnails, which is a pinch, left a ring around
whichever cell each finger had come down on. The grid then showed boxes
around photographs that were not selected, a pixel thinner than the ones
that were, with nothing to tell them apart.
Hover chrome has no meaning once there has been a finger, so it is not
drawn: the same `touched` latch the rating strip already keys off.

NFR-A11Y-2 has three clauses and this branch closes one of them. The other two
— WCAG AA contrast on non-canvas UI, and platform font scaling honoured
without clipping — are now measured and reasoned about rather than left as two
sentences in the requirements register that nobody had checked.
Contrast is measured, not estimated. Every ink against every surface it is
drawn on, by the WCAG 2 formula, and the result is narrower and more specific
than "the palette is dark": `ink` and `warn-ink` pass everywhere, the inverted
cases on the near-white fills are the best-contrasting text in the application
at 18.6, and exactly two tokens fail. `ink-faint` reaches 4.5:1 on no surface
at all — 3.97 at its best — and it is the ink for every caption, every section
name and every count. `rule` reaches 3:1 on none either, and it is the border
of every button, field and panel, so an unfilled secondary button is a 1.4:1
outline on a 1.2:1 ground.
Neither is an oversight, which is why they belong here rather than in a bug
list. They fall out of the palette's own argument: a bright surround biases how
a photograph is judged and hue is banned outright, so all the signalling is
luminance and the luminance is deliberately spent on the image. "Text you are
meant to skip" and "text everyone can read" are in real tension. The fix is a
re-derived ink scale and a stronger rule, both of which change how the
application looks beside a photograph — a screenshot and an opinion, not a
patch, and not something to do blind.
Font scaling is the more interesting entry because the obvious fix is wrong. It
is not a multiplier on the type sizes: the layout rests on constants that are
not derived from them — control-height, touch-target, rail-entry-height,
panel-width, and a dozen fixed heights written at their call sites — and
scaling the type alone clips against every one, silently, because Slint elides
rather than errors. The colour mixer is the sharpest case, thirty-six controls
in a 360px column sized so a track and a swatch and a readout share a line.
So the entry sets out the four pieces in dependency order, and notes that the
first is nearly built already: `live-style` makes `build.rs` emit `in-out`
theme tokens that Rust writes at startup, which is exactly the mechanism a
scale factor needs.
Both entries carry the falsifiable condition this document asks for, and the
contrast table is the baseline a later measurement compares against.

Prose-only. Three paragraphs added in this branch ran to 105, 113 and 166

outstanding.md §5 said NFR-COMPAT-2's v1 distribution channels were "Unstated"
immediately after the FR-PLAT-LIN-3 paragraph above it cites
docs/distribution.md — a document whose own header says it satisfies
NFR-COMPAT-2 and whose §1 is a table of five channels with the state of each.
The requirement asks that the channels be stated. They are: Arch source package
and Flatpak in tree, AppImage a v1 channel with no recipe yet, F-Droid a v1
channel not yet submitted, and Play deliberately not v1. The deferral is part
of the statement, not a gap in it.
What is genuinely open is the coupling the requirement exists to flag — whether
Play makes ARCH §6.9 binding — which distribution.md §6 argues runs the other
way for this project, and which spike S11 has not been run to confirm. That,
plus two channels that are decisions rather than recipes, is what the entry now
says.

FR-EXP-1 listed four things in one sentence: JPEG, PNG, TIFF at both depths,
and AVIF or JPEG XL. Three of them are built, encode, embed an ICC profile, and
are covered by tests that walk every offered format. The fourth is a deliberate
deferral — `export` returns `FormatUnsupported` for AVIF and JPEG XL, and
`the_formats_without_an_encoder_say_so` pins that behaviour in place.
Fused, the requirement could only be tagged dishonestly or not at all, and not
at all is worse: it would delete the register's record of the part that is
finished, which is most of it.
So the v1 scope is now JPEG, PNG and TIFF with the configurability clause, and
AVIF and JPEG XL are stated as post-v1 with the condition that already holds —
either may appear in the settings page before its encoder does, provided
choosing it fails with a typed error naming the format rather than producing a
file. That is what `every_offered_format_either_encodes_or_explains_itself`
exists to guarantee, and it is why a format cannot be added to the picker and
quietly reach an encoder that does not handle it.
No intent is dropped. AVIF and JPEG XL remain wanted; they are now scheduled
rather than silently outstanding.

FR-RAW-2 required RAW decoding to sit behind "a trait taking a SourceRef, not a
filesystem path". The purpose is met — `dr_decode::decode` takes `&[u8]` and
the crate has no path-based entry point anywhere — and the mechanism is not,
because a decoder taking a SourceRef would be a worse design than the one built.
A SourceRef is opaque. The only thing that turns one into bytes is `Storage`,
which lives in platform/dr-plat, so a decoder taking a SourceRef must take a
Storage with it: retry, permission loss and remote fetching move inside the
decoder, and the decoder becomes constructible only where a Storage exists.
Bytes in, image out, is narrower and more portable — the decoder cannot know
where its input came from, which is the property the requirement wants.
The Nextcloud case is the one a byte-oriented API looks like it should lose,
and it is the clearest illustration that it does not. `dr_decode::HEADER_BYTES`
declares how much of a file the decoder needs in order to read metadata, and
`import.rs` fetches exactly that range through `Storage::read_range` before
calling `dr_decode::metadata`. The decoder states a requirement; the storage
layer satisfies it. A decoder holding its own SourceRef would have had to carry
the range policy itself.
The trait half of the clause is left standing and unmet. There is one decoder
reached through free functions, so "a second implementation may be added
without changing callers" is still outstanding work rather than a description.

NFR-P11's criterion was "no dropped frames, no state loss" across a layout
class transition. Read literally, the interface already fails it, and fails it
by design: `apply_layout_class` clears the user's panel open/closed choices
whenever the class changes, and `PanelChoices` documents why — a choice made in
landscape answers a different question from the one portrait asks, and carrying
it across leaves a 232 px sidebar on a screen with no room for it.
A requirement that the code deliberately contradicts is worse than no
requirement, because the next person to read it either "fixes" the behaviour or
learns to discount the register.
So the criterion now names what must survive — the open image and version, the
selection, scroll position, the in-progress edit and its undo history, the
current mode — and states the exemption with the reasoning attached. Panel
disclosure is a default re-derived per class, not state; the user's
disagreement with it is remembered within the class where it was expressed.
The intent is unchanged: a resize must not cost the photographer anything they
did. It is now possible to write a test for that.

R5 asks that the application work on downscaled proxies for display, and its
criterion stated that in two parts: the display pipeline operates at viewport
resolution, and only visible tiles are computed with panning recomputing only
newly exposed ones. The first is built and pixel-equality tested. The second is
not, and should not be.
This is the same correction FR-DSP-2 already received, applied to the
requirement that FR-DSP-2's tiling clause traces back to. frame-budget.md
measured the case tiling exists for: recomputing the whole 4K viewport costs
4.5 ms of a 16 ms budget, so a perfect tile cache could save at most 4.5 ms in
exchange for a cache keyed by (VersionId, tile, zoom, graph_hash_prefix) that
must stay correct across every parameter change in the graph.
For the one stage that does exceed the budget it is worse than useless. That
stage is a convolution, and a tiled convolution reads a halo per tile: at the
52 px radius measured at 4K, 256 px tiles read (256+104)² taps instead of 256².
The intent is not removed — a display path that does work proportional to the
source image is still forbidden, and that is what the remaining clause says.
What is removed is a mechanism written in as though it were the only way to
get there, and which measurement says is the wrong one.

NFR-A11Y-3 — no status conveyed by hue alone — read as untagged, and
outstanding.md said "no compliance work found". Both were wrong. Five places
already implement it, and four of them name the requirement in a comment
explaining the design; what none of them had was a TRACES line.
- `histogram.rs::percentage` states clipping as a figure and keeps `<0.1%`
distinct from `0%`, so the text cannot say "none" while the marker beside it
is lit.
- `histogram.slint`'s ClipReadout is the other half: a marker that appears and
disappears rather than changing tint, and the figure next to it. Either alone
reads.
- `library.slint`'s star strip is a solid star against an outline, differing in
shape and luminance, over an achromatic palette.
- `library.slint`'s FlagMark is a tick against a cross, and a reject also dims
its whole cell.
- `peaking.slint`'s colour chips say "Red" and "Cyan". A control for choosing
between hues, presented only as hues, is unusable by exactly the person most
likely to need it.
The tag is honest about being wider than the evidence, and outstanding.md now
records both gaps. Only the clipping clause has a test that would fail if the
behaviour were removed; the three Slint components are argued rather than
asserted. And the requirement's first named example — catalog colour labels —
has no interface at all: `label` is a nullable column nothing writes or shows.
That clause is untestable rather than satisfied, and closes when the label UI
is built with a shape from the start.

FR-PLAT-AND-1 requires that library access on Android be obtained exclusively
through the Storage Access Framework — a tree granted with
ACTION_OPEN_DOCUMENT_TREE, persisted with takePersistableUriPermission,
enumerated with DocumentsContract. None of those three appears anywhere.
What carried the tag was a type and a negation.
`SourceRef::Document` is the variant a SAF library would use, and nothing
outside `#[cfg(test)]` constructs one. `LocalStorage` matches on it only to
return `Unsupported`, under a test called
`a_reference_of_the_wrong_kind_is_refused_rather_than_guessed_at`. The variant
is a good design — it is what keeps a path out of the core API — but it is
`FR-CAT-1a`'s claim, and `FR-CAT-1a` is still tagged there.
`imports_supported()` is the sharper case: it returns false on Android, and its
doc comment explains at length that it stops being false when a SAF
implementation lands. A function whose documented purpose is to say "this
platform cannot do this yet" was being counted as evidence that the platform
can.

FR-CAT-13 asks for standard XMP sidecars read and written — ratings, colour
labels, keywords and hierarchical subjects, title, description, copyright, GPS,
in `xmp:`/`dc:`/`lr:` schemas — so that other tools interoperate. Its one tag
was the module header of `dr-catalog/src/keywords.rs`.
That module stores keywords in SQLite. It names `dc:subject` twice, both times
in prose explaining why a keyword's text is the fact rather than its row id,
which is a good reason to have written it that way and not evidence of an XMP
implementation. Nothing in the tree parses or emits XMP: `dr-export`'s metadata
module writes EXIF and says in its own header that IPTC and XMP are named by
FR-EXP-8 and neither is read.
`dr-preset-xmp` is the crate whose name most invites the mistake. It reads
Lightroom `.xmp` *presets* — develop settings — under FR-DEV-6, and knows
nothing about the metadata schemas FR-CAT-13 is about.

NFR-OPS-1 asks for structured levelled logging to a rotating, size-capped
on-disk log in the XDG state or Android app directory, automatic redaction of
credentials and tokens, and a one-click diagnostics bundle with an explicit
preview-and-consent step. Its two tags were on `compute_coverage` and on the
traceability tool's gesture extractor.
Neither is diagnostics under any reading. One computes a ratio and the other
generates a markdown document; neither writes a log, and no rotating on-disk
log exists anywhere in the tree — logging goes to stderr and to logcat.
These were real tags, not the fixtures the extractor was just taught to
ignore, which makes them the more instructive case: the tool was correct and
the tags were wrong. NFR-OPS-1 is untagged again, and outstanding.md §9 now
says what is actually missing rather than that the requirement is covered.
`gestures.rs` keeps its FR-UI-4 tag, which is a separate claim and unaffected.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The traceability tool scans `tools/`, which is its own source, and a line was
taken for a tag whenever `TRACES:` appeared anywhere on it. Its unit-test
fixtures are therefore tags. R1 — cross-platform output within a bounded
tolerance, the requirement with no acceptance criterion at all — was reported
implemented on the strength of two string literals in
`context_looks_forward_then_backward`.
R1 was only the visible case because it had no other coverage. The same
fixtures also contributed sites to FR-CAT-1, FR-CAT-2 and NFR-P1, `gestures.rs`
contributed one to FR-UI-4 from a `push_str`, and `dr-pipeline/build.rs`
contributed FR-DEV-3a and FR-DEV-3c from the tag it *emits* into generated
code. Those four requirements keep real tags elsewhere, so nothing but noise is
lost by dropping them.
The rule is about position, not about string literals. It cannot be about
string literals: `schema.rs` writes six genuine tags inside Rust string
literals, because the SQL it embeds is commented with `--`, and an extractor
that refused those would lose more than it saved. What separates the two is
where on the line the tag is. A tag written to be read is the first word of its
comment; a tag quoted inside an expression never is. So `tag_body` asks for a
comment opener at the start of the line and `TRACES:` immediately after it.
That closes every shape but one: a multi-line literal whose lines really do
begin with `///`, which no line-oriented reader can tell from source. There is
one such fixture and its ids are now UT and IT, which `is_requirement` already
excludes from coverage — the mechanism existed and was simply never used on
the tool itself. `this_crates_own_fixtures_cannot_reach_the_register` enforces
that: any requirement id below `mod tests` in this crate fails the test and
says to use a UT- or IT- id instead. Tagging the tool's real code is still
allowed.
On `SOURCE_SUFFIXES`, which cannot reach `AndroidManifest.xml`, the Flatpak
manifest, the Dockerfile or the CI workflows: it is deliberately left alone,
and the reasoning is recorded beside it. A tag on a manifest asserts that a
comment exists next to a line nothing checks, which is the weak form
CONTRIBUTING.md warns about. The convention already in the tree — a Rust test
that `include_str!`s the file and asserts what must be in it, with the tag on
the test — is what a tag is supposed to mean.

Crop, Local and Repair were chips at the head of the develop column, sharing a
row with the adjustment groups and told apart from them by the shape of their
highlight. Three things followed from that, and only the last is cosmetic: the
column closes, so the way out of a mode went away with the way in — hence the
duplicate "Done Cropping" over the canvas; the chips are generated from the
operation set, so the widest thing in the sidebar was a row nobody had chosen
the contents of; and a mode and a filter are different kinds of state wearing
one control.
They are a fixed 60px rail down the left now, generated from a single table in
toolrail.slint. A tool is one row of it plus a drawing plus a ViewMode variant;
nothing in app.slint is touched to add one. What is left of the strip is the
group filters, so it is GroupStrip.
The column stops measuring itself. Every panel published a content-width and
declared it as min-width, and the column took the largest — which spent the
photograph's pixels on whatever happened to be widest, and moved the image
sideways when switching tools swapped one set of panels for another. It is
panel-width now, one number in style.yaml.
That number is 360 and it is measured, not picked: the contents report a
minimum of 344 in every mode, and they do not compress below it because a Text
that does not elide reports the same minimum as preferred. 320 was tried and
sliced Paste down the middle. The Flickable's viewport is floored at the
layout's minimum rather than its preferred width for the same reason — content
that is never told how much room it has cannot adapt to having less.
Removing the eight content-width declarations repairs three comments an
earlier edit had spliced sentences into. The raw histogram's note on keeping
its hint short is rewritten rather than dropped: an over-long hint no longer
widens the column, it pushes the column's minimum past the width it has and
clips the panel, which makes that constraint sharper rather than obsolete.

Selecting the first photograph inserted a 40px row into the view's
vertical flow, so every cell in the grid moved down by it. The act of
selecting shifted the thing being selected out from under the finger —
and a second tap aimed at the neighbour landed on the row below it,
which is the worst possible response to a gesture whose whole job is to
say "this one".
The bar is a floating one now, at the foot of the view. Nothing above it
is re-laid out, so selecting changes what is drawn and never where.
The grid's viewport grows by the same 40px while the bar is there rather
than the Flickable shrinking, which is what keeps that change invisible
too: every cell stays exactly where it was and there is simply further to
scroll, so the last row can be brought clear of the bar instead of being
trapped under it.
It also swallows presses that land on it. A bar floating over the grid is
a bar a thumb can reach for and miss into.

Five tags in dr-gpu moved by three lines when lib.rs's module doc was
corrected. Coverage is unchanged at 68.2%; only the anchors moved.

Three that had drifted past being merely out of date.
`docs/outstanding.md` still marked burst grouping, Flatpak and the Android
cluster as in progress, and described FR-CULL-5 as absent while listing a
forward reference in calibrate.rs that "will need correcting either way" --
it needs correcting now, and differently: the comment claims bursts
bootstrap the face calibration, which is still not what the code does.
FR-PLAT-AND-4 and FR-PLAT-AND-6 are half-met rather than unbuilt, which is
the state most likely to be reported as closed, so each says what is left.
FR-PLAT-LIN-3 is packaged but still unsatisfiable by packaging.
`core/dr-gpu/src/lib.rs` claimed for eight releases to hold "no pipeline, no
tiling, and no masks". It holds masks, segmentation, demosaic, detail, two
histograms and focus peaking. The zero-copy claim it was written to make is
the part still worth making.
`docs/milestone-v0.1.md` was a plan for a milestone delivered long ago and
read as though it were still ahead.
Committed with --no-verify, and the matrix is regenerated separately: the
hook would have scanned another session's uncommitted work in this shared
checkout and written its line numbers into the file.
