dtourolleandClaude Opus 5 485297f0c6 Let a mask cover a whole category, not just one instance
`MaskSource` could say "instance 3 of that segmentation run" but had no way
to say "the sky". Adding `Category { signature, name }` beside `Subject` is
what lets a local adjustment attach to a semantic category at all.

Stored as identity like a subject, and for the same reason: the coverage is
megabytes and is reproducible by running the same model over the same image,
so the sidecar carries what finds it again and the session carries pixels.

## A name rather than an index

An index would be smaller and would match `Subject`. It would also be a bug.
The grouping lives in `models/scene/categories.txt`, which is editable by
design — adding one category to it renumbers every category after it, and
every stored layer would silently start grading something else. A name that
no longer exists is simply not found and the layer reads as stale, which is
the failure that announces itself.

Staleness is otherwise identical to a subject's: the coverage buffer is in
the session, never the sidecar, so a signature from another run points at
pixels that were never computed.

## Two tests, and the second one caught a real shape

Round-tripping the name matters more than usual here, because the whole
argument for storing a name instead of an index is worthless if the sidecar
is what drops it.

The multi-word case is the one worth having: `category = swimming pool` is
written on one line, and a reader splitting on whitespace would have
truncated it to a category no model has — a layer that silently masks
nothing. `category` is also its own key rather than a reuse of `class`,
because a file conflating them would round-trip a subject into a category.

dtourolleandClaude Opus 5 99563b33f7 Record the one clause of FR-PLG-8 that is built, and say what it is short of
FR-PLG-8 reads as unbuilt, and most of it is: no aggregated missing-plugin
notice, no catalog-wide view, no export gate, no mark on an image whose
operation is unavailable. But its opening sentence is a claim about existing
behaviour — "the sidecar already preserves lines it does not understand
verbatim and writes them back untouched" — and it goes on to say that property
"is now load-bearing and shall be treated as such".

Two tests treat it as such, and neither was tagged. `sidecar.rs` keeps an
unknown operation across a parse-and-write, and keeps it out of the edit graph
so that preserving it is safe rather than merely tidy. Both would fail if the
verbatim path were removed, which is what CONTRIBUTING.md asks a tag to mean.

The tag sits on the two tests rather than on the module, so the matrix points
at the clause that is closed rather than at the requirement as a whole.

It is still short of the requirement's own acceptance criterion, and the tag
comment says so: FR-PLG-8 asks that a sidecar written with a plugin, opened and
saved without it, be byte-identical to the original, and the test asserts
`contains`. Both halves exist separately — `writing_the_same_state_twice_is_byte_identical`
proves byte identity for content this build understands — and nothing joins
them into the single claim the requirement makes.

dtourolleandClaude Opus 5 ab0ef6a26d Say which requirements the code was already satisfying
Thirteen requirements were surveyed as built but untagged. Eight of them
were: R3, R6, FR-DEV-1, FR-UI-6, FR-NC-6d, NFR-OPS-3, NFR-PORT-2 and
NFR-SEC-3. Each was read against its full text in requirements.md and
against the code before the tag was added, because a tag that is wrong is
worse than an absent one — it turns a visible gap into an invisible one.

The five that were refused, and why, because the reasoning is the part
worth keeping:

R2 carries "(figure TBD)" in its own acceptance criterion and asks for a
stated prefetch margin and cache-hit rate; neither figure exists anywhere
in the tree and neither quantity is measured, while TD-2 and TD-3 both
describe the thumbnail path falling short of it.

R5 asks for three things and the code does one. The display pipeline does
run at viewport resolution, but "only visible tiles are computed" and
"panning recomputes only newly exposed tiles" need a tile scheduler that
does not exist — and frame_budget.rs currently argues for striking tiled
computation from the interactive path rather than building it.

FR-RAW-2 asks for a trait taking a SourceRef, so that a second decoder can
be added without changing callers. What exists is free functions over
&[u8]. That meets the requirement's stated *purpose* — the same decoder
serves a local file, a SAF document and a byte range, which is exactly why
it takes bytes — but there is no trait and no second implementation seam,
so the requirement should probably be amended rather than tagged.

NFR-ARCH-1 asks for named executors with stated thread counts.
architecture.md §7.1 states the table; nothing implements it. Workers are
twenty-odd ad-hoc std::thread::spawn sites, each building its own
one-worker tokio runtime, with no decode pool, no GPU-submit executor and
no I/O pool. The requirement's own text says R4 and NFR-P9 "assert an
outcome with no stated means", and that is still true.

NFR-SEC-4 is satisfied by absence — there is no telemetry — and absence
has no module to tag. A tag would point at nothing.

NFR-OPS-3 was the closest call of the eight taken. The store is single,
separate from the catalog, survives a catalog rebuild and does not sync
between devices; it has no version *field*, deliberately, and
settings.rs argues why and names the condition that would need one. The
substance is met and the reasoning is recorded where it belongs.

dtourolleandClaude Opus 5 0c3b8cb1c4 Hand out descriptors a declaration could produce
`Operation::descriptor()` returned `&'static OpDescriptor`, and that lifetime
is the whole reason a build-time node is free and a run-time node is
impossible: only a compile-time literal can satisfy it, so no amount of
reading `ops/*.yaml` at startup could ever produce a descriptor the rest of
the application would accept. FR-PLG-2 says a bundled operation and a
third-party plugin are the same kind of thing, differing only in where the
file was found — and a lifetime outsiders cannot meet is exactly the second,
weaker format that requirement forbids.

So a descriptor is now owned and handed out as `Arc<OpDescriptor>`, with `Vec`
where it held `&'static` slices. `Arc` rather than a `&self`-borrowed
reference because the callers want to *keep* it: the develop panel collects
descriptors and then mutates the graph, and a borrow would tie the
descriptor's lifetime to a borrow of the operation it came from, which is the
one thing `&'static` was doing right.

The identifier newtypes deliberately did not follow. `ParamId` is `Copy`, is
compared in `match` arms against generated constants, is a map key in the
sidecar and history, and reaches Slint model rows; an `Arc<str>` there would
cost a refcount on every one of those and would take `match id { EXPOSURE =>
.. }` away from the generated code. They gain an interner instead, which is
honest about its lifetime rather than pretending to one — the set of ids is
bounded by deduplication and is process-lifetime by construction, because the
sidecar on disk names its parameters and an id has to stay resolvable for as
long as any edit naming it can be opened.

No behaviour changes. Every descriptor that was a `static` is a `LazyLock`
initialiser now, `Operation::helpers` borrows from `self` instead of being
`'static` so a future run-time node can own its list, and `Warp` and `Framing`
follow `Operation` so there is one shape rather than two.

The one place a descriptor is read per frame is `compose_full`, which takes
`descriptor().id` to prefix each active operation's uniforms, and `dr-ui`
composes on every frame it draws. That is a dozen atomic increments beside a
composition that is already building several kilobytes of WGSL on the same
call; it is noted at the trait method rather than left for a profiler to find.

dtourolleandClaude Opus 5 93efdf27a6 Keep the film stock when an edit is saved
`Version::update` is the write path an automatic save goes through. It copied
the parameters and the masks and said nothing about the film, so a photograph
developed on a stock was written back without it and opened the next time
without its emulsion. Nothing reported a failure — the line was simply not
there.

It is the third of the three routines that captured "the edit" and the only
one that got it wrong, which is the argument for not having three. All of them
now destructure one `EditState`, so `from_graph`, `update` and `apply` cannot
disagree about what an edit consists of, and the next part of one cannot be
lost by anybody writing a line too few.

Two tests, both of which fail without the fix: the field survives `update`,
and the stock survives the round trip through the file. `apply` returns the
`FilmRebake` it always implicitly owed, so `apply_version` now reads the debt
off the call rather than off `version.film` — and pays it in both directions,
since a version with no film has to clear the adjust pass too or it keeps
textures bound that nothing will sample.

dtourolleandClaude Opus 5 5622a58ce3 Give an edit one complete state, and make omitting part of it a compile error
An edit used to be a bag of scalars. That stopped being true when the mask
stack and the film stock arrived, both deliberately held apart from `ops`
because a layer is not a scalar and a stock is not a scalar — and nothing
announced the change. What happened instead is that three routines each
captured "the edit" and each captured a different subset of it.

`EditState` is all of it: the parameter map, the masks, the stock. What keeps
it complete is not a comment. `EditGraph::state` destructures the graph
exhaustively, `EditGraph::set_state` destructures the state exhaustively, and
the fields are public so every construction site is a struct literal naming
all of them. Adding a fifth kind of graph state — FR-DEV-8's spot removal is
the one already asked for — fails to compile until somebody has decided
whether an undo has to put it back. Verified both ways round by adding a field
to each type and watching five call sites refuse to build.

A compiler error rather than a runtime check, because the failure being
prevented is silence: the missing halves produced no panic, no warning and no
failing test.

The stack is now shared rather than owned, and that is about the drag path
rather than memory: `state` runs on every parameter change, which during a
drag is once a frame, and deep-copying a painted brush sixty times a second to
record an exposure move would be a cost paid for nothing. `masks_mut` is the
one door a stack is modified through, so it clones on write.

`FilmRebake` is the one thing a caller is still owed. Restoring a stock always
needed the profile database this crate does not link (ARCH §6.5a); it was a
comment before, and it is a `#[must_use]` return value now.

dtourolleandClaude Opus 5 44444f7768 Write the repairs down, one line each, and merge them by id
A spot is eight numbers, so it goes in the version block as a line rather
than in a block of its own the way a mask does — sixty-four blocks would
bury the rest of the file. A line per spot rather than one line for the
set, because the line is what a diff shows and what a merge resolves.

The parse arm sits ahead of the op.param arm deliberately: without it,
`spot.abc123 = 0.4 0.6 …` reads as an operation called `spot` whose value
will not parse, and the repair is dropped with a warning about a corrupt
number. The prefix is safe precisely because a spot is not an operation,
so no ops/ declaration can claim the name.

Merging is merge_masks by id, one level down, and it is where the derived
ids earn their keep: two devices that removed different marks hold
different ids and both survive, while two that removed the same piece of
dust hold the same id and the merge sees the one repair it is. A spot both
sides dragged resolves whole to the higher revision — eight numbers
describe one disc, and half of each is a repair neither photographer made.

dtourolleandClaude Opus 5 3b5952769b Emit floats an f32 can hold, and drop the format! that formats nothing
CI runs cargo fmt --check and clippy -D warnings, and this branch had
never been through either. Both would have failed it.

The bulk was the generated colour tables: eight significant figures where
an f32 carries about 7.2, so the eighth is noise that rounds away at
compile time and clippy's excessive_precision says so 109 times over.
Fixed in the generator rather than only in the file, so it stays fixed --
and the file is trimmed in place rather than re-derived, because
regenerating it needs a colour-science stack that has nothing to do with
the defect.

The format! in the composer is mine too, from extracting the rendering
tail: the braces in it were escaped because the text used to live inside a
larger template, and once extracted the escapes are noise and the call
formats nothing.

Also here, and clearly not mine: an unused import and a shadowed binding
in dr-gpu, and an unused import in a test. They are pre-existing --
clippy has been failing on master before this branch existed, on lints
like is_multiple_of that arrived with a toolchain rather than with
anyone's code. Fixed because CI cannot go green around them, and called
out because a merge commit is a bad place to quietly edit someone else's
crate.

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 c75849040c Format the tree the way the gate asks for it
`cargo fmt --check` is a required step and had drifted across 45 files. Most of
it arrived this week: several operations were written in parallel worktrees and
merged by hand, and a hand-merge resolves conflicts without ever running the
formatter over the result.

No behaviour changes — this is `cargo fmt --all` and nothing else, kept as its
own commit so the next reader can skip it wholesale rather than search it for
one that matters.

dtourolleandClaude Opus 5 d64a61d677 Give the tone curve a curve for each colour channel
The declaration in ops/tone_curve.yaml has claimed per-channel curves since
it was written — it is the justification for the operation carrying both
`tone` and `colour`. Only the master curve existed. This is the other three.

The master runs first and the channels grade its result. Both orders are
real images and they differ visibly, so the choice is made and written down
rather than left to the loop: a point placed on the blue curve should act on
the tone the photographer can see, which is what the master has already
produced. The other order anchors the grade to tones the master is about to
move, so adjusting contrast slides a warm shadow up into the midtones.

Every id that existed before today is spelled exactly as it was. The master
curve keeps `p2_y` and the new curves take `r_`, `g_` and `b_` prefixes, so
a sidecar written when there was one curve loads, means what it meant, and
renders the same shader — asserted on the generated source, not on the
parameter values. Nothing needed a version check because nothing was
renamed.

Each curve reaches the shader only when it has been moved off the diagonal,
so an S-curve and no colour work generates what it generated when this
operation held ten parameters instead of forty, down to the uniform names.
The monotonicity guarantee is enforced per curve: a coincident pair on blue
divides by zero exactly as thoroughly as one on the master.

dtourolleandClaude Opus 5 c396a22dfd Paint a mask without ever rasterising one on the CPU
The last line of FR-DEV-3, and the mask ARCH §5.4 was written for. darktable
rasterises drawn masks on the CPU and users call the result unworkable; the
architecture's answer is that a stroke arrives as *parameters* and the device
draws it. This is that, from the model through the sidecar to the pixels — but
not the finger: the canvas is somebody else's change, and this leaves it a
seam rather than reaching into it.

**A stroke is a swept disc along a polyline**, plus erase, radius, hardness and
flow. `MaskSource::Brush` holds an ordered list of them, and the order is the
mask: an erase after an add takes it away and the same pair reversed does not.
Nothing about it is pixels, which is what makes a mask that costs a line of
text, diffs by the gesture, and survives a crop, a straighten and an export at
any size — the properties a stored raster has none of, and the same argument
the region ids were chosen for.

Two things keep the point count honest. While the finger is down, a position
closer to the last than an eighth of the radius is dropped: a touch screen
reports 120 a second, so a finger held still for five seconds is six hundred
points in the same place, and simplification would only remove them once the
gesture had ended — after every frame in between had drawn all of them. When
it ends, Douglas–Peucker at an eighth of the radius removes what a disc that
wide cannot express: a swept circle moved by r/8 moves its own edge by r/8,
which is inside the soft part of any brush. Coordinates snap to a
ten-thousandth of the frame on the way in *and* are written at that precision,
so a round trip is exact rather than nearly exact — a file that drifts in the
sixth decimal every save is a per-field merge conflict a day, over nothing.

**Cost is why the strokes are not drawn by the full-screen triangle the other
masks use.** A swept disc is the minimum distance to any of its segments, so a
stroke over the whole frame costs `pixels × segments` and both terms grow
together — the quadratic that is darktable's problem moved onto the GPU rather
than solved. Each stroke is instead drawn over its own bounding box, grown by
the radius, so the rasteriser never invokes the shader for a pixel the stroke
cannot reach: `area(box) × segments`, which for a dab or a swipe is a small
fraction of the frame. A gesture past 256 points continues as a second stroke
for the same reason, since a shorter stroke has a smaller box.

Add and erase are `dst + a(1 - dst)` and `dst(1 - a)`, which are exactly a
source-over and a one-minus-source blend — so they are blend state, not
arithmetic, and no pass ever reads the slice it is writing. That is what
permits one draw per stroke at all. Within a stroke the coverage is the
*minimum* distance over its segments rather than a sum: a path that crosses
itself must not build up where it did, or every circle and every scribble
would be blotchy wherever consecutive dabs overlap, which is everywhere.

Not a distance field, deliberately. `dr-segment`'s transform documents the two
conditions that make CPU work right there — once per mask edit, over input
already CPU-side — and a stroke fails both: it changes while the finger moves,
and its input is a handful of coordinates that never needed to be pixels. It
also needs no transform, because the distance to a swept disc is closed form.
A stroke is the one mask whose distance field is known without computing one.

An unpainted brush layer is inactive rather than empty, which is not an
optimisation: `invert` turns empty into everything, so a layer created with
invert already set would apply its adjustment to the whole photograph before a
single stroke was made. That is the loud, confident kind of wrong this codebase
refuses everywhere else a mask can go missing, and there is a rendered test for
it.

The tests read pixels back off a device rather than checking that the two
halves agree with each other. What they pin down is what is silent when wrong:
the y flip between mask space and clip space, which a centred stroke would not
notice; a bounding box not grown by the radius, which makes a tap draw nothing
at all; an aspect ratio ignored, which makes a dab an ellipse on any frame that
is not square; a stroke doubling back and building up; and an erase that lost
its place in the order and put back paint the user had taken off.

Not done here: the interaction. The canvas needs to begin, extend and end a
stroke on the active layer, and `DevelopSession::rasterise_masks` still returns
early without a segmentation — it takes the proxy size from one, and a brush
needs no model to have run over the photograph first.

dtourolle ee10097435 Mask the subject the model found, not the regions underneath it
The watershed hierarchy does not survive a photograph, so local masking
stops depending on it. A layer can now be one recognised object, and the
object's own coverage is the mask.

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

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

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

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

`examples/local.rs` is the worked example: subject in colour with the rest
monochrome, and the subject lifted out of its background. Run on a 5472x3648
CR2 it finds two people and two cars, and the colour-pop keeps her hat and
hair while the wall and grass behind go grey.

dtourolle b1433ad4a9 Give a mask an edge treatment, and find out the watershed has none worth having
Two things, and the second is why the first matters more than expected.

Mask layers gain a feather, a falloff curve and a morphology, all defined
against a signed distance from the boundary rather than as separate
features — one exact distance field answers "how soft" and "how far" at
once, so dilation is a threshold at -r, erosion one at +r, and closing and
opening are one of each in sequence. The compound pair costs a second
distance field, which is why they are named rather than presented as a
radius that happens to be signed. Types, defaults and sidecar round-trip
only; the field itself is next.

`edge-feather` and `edge-falloff`, not `feather` and `falloff`, because a
radial mask already writes `feather` for the fraction of its radius it
ramps over. Same word, different quantity, different units — sharing the
key would have made an existing file ambiguous.

The diagnostic that provoked this is committed as an ignored test, because
"does the ladder land on things a person means" is the question S15 exists
to answer and it should not depend on whoever still has the script. On
bus.jpg it answers badly: 35,075 regions at blur 2 over an 810x1080 frame,
and cutting that to 400 gives *one* region covering nearly the whole
picture plus 399 noise specks. Not over-segmentation — collapse. Almost
every saddle is near zero, so the merge order joins everything meaningful
before it joins anything spurious, and a global cut spends its entire
budget on grain.

So the granularity ladder does not currently work on a photograph, and the
region masks built on it inherit that. Recorded rather than worked around:
the next commits move local masking onto the model's instances, where the
edge treatment above is what makes a quarter-resolution mask usable.

dtourolle 94cfea4748 Keep the mask when the app closes, and when two devices disagree
The sidecar is authoritative — the catalog is a disposable index and the
RAW is never written — so a mask that does not round-trip is not a
persistence bug, it is lost work.

Layers get their own `[mask <version> <id>]` blocks rather than being
flattened into dotted keys. A layer is not a scalar: it carries a
selection, a geometry and a chain of its own, and encoding a region set as
`m1.region.0 = 12` would be neither readable nor mergeable. The version
uuid is repeated in the header instead of relying on the block following
its version, because "belongs to whichever version appeared above me" is a
relationship that hand-editing, merging and older builds each break
quietly.

Region ids sort and deduplicate on read rather than being trusted from the
file. The mask's identity is the *set*, so two devices writing the same
selection in different orders must produce the same mask rather than
argue about a difference that is not one.

Masks merge by layer id under FR-NC-9, which is the disjoint-survives rule
the parameters already follow one level up: a layer added on the phone and
one added on the desktop both survive. A layer *both* sides edited resolves
wholesale to the higher revision, because half of one selection plus half
of another's opacity is a layer neither person made. A remote deletion is
honoured, or a mask the user removed returns on every sync.

An unknown mask source is skipped rather than guessed at. Applying a newer
format's mask type as the nearest one this build knows would put a
confidently wrong adjustment on the photograph, which is worse than
applying none.

29 new tests. The interesting ones are about silence: a maskless version
clearing the previous image's layers, a bare selection persisting even
though it renders nothing, and a mask naming a version that is not in the
file being dropped instead of landing on whichever block was open.

**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 7c57f490fe Declare a develop operation in YAML, and generate the rest
An operation was, in the overwhelming majority of cases, four facts: what
its parameters are, what uniforms they compute, what WGSL those uniforms
drive, and where it sits in the chain. Written in Rust those four facts
arrived wrapped in ninety lines of trait implementation — a match on
parameter id to a struct field, another match back, an is_active comparing
each field to its default, a Vec<Uniform> built by hand. All mechanical,
and each one a place to make a silent mistake: a param() arm returning the
wrong field reads perfectly and breaks the sidecar round-trip.

So the four facts are the file now. core/dr-pipeline/ops/<id>.yaml is a
node, build.rs compiles it into the same Operation impl as before, and the
result lands in OUT_DIR — the same reasoning as style.yaml -> theme.slint,
including why it does not land beside the sources it would look exactly
like. Nothing downstream can tell a declared node from a hand-written one:
same &'static OpDescriptor, same fused-shader composition, same sidecar.

Nine nodes moved: exposure, white_balance, contrast, highlights_shadows,
blacks_whites, brilliance, vibrance, saturation, and the shared WGSL
helper registry. Their prose came with them, and so did their tests —
set/expect/expect_active/expect_wgsl in the declaration compile to real
#[test]s, so a node file carries its own proof rather than leaving it
behind in a file that no longer exists.

Two stayed in Rust and say so with `rust:`. The tone curve's neutral is a
relationship between five interpolated points rather than a set of values;
the colour mixer generates thirty-six faceted parameters from twelve
computed hue bands. A schema stretched to cover either would be a worse
language than Rust aimed at one caller. They still declare their position
here, because the chain's *order* is the one thing a reader comes to this
directory to learn, and an order written half in YAML and half in Rust
would be worse than either alone. default_chain() is generated from it.

Uniforms are derived by a small expression language — exp2(exposure),
blacks / 100 * 0.02 — compiled to Rust rather than interpreted, so an
unknown name or a wrong arity is a build error naming the file and the key
and the arithmetic costs nothing at runtime. The build script refuses a
duplicate order, a filename disagreeing with its id, a default outside its
own range, a test value the graph would clamp before the node saw it, a
helper that does not define the function it names, and a declared node
colliding with a file in src/ops.

Verified by adding a scratch node and removing it again: one file, no
other edit, and it joined the chain at its declared order with its test
running. 237 tests pass in dr-pipeline, clippy and fmt clean.

.yaml joins the traceability tool's scanned suffixes, because a node's
Rust now lives in OUT_DIR where a tag could never be linked from the
report. Coverage 47.7% -> 48.3%.

dtourolleandClaude Opus 5 489465faf0 Show the photograph the way it was taken
Nothing read EXIF orientation, so every frame from a body held sideways
lay on its side — in the grid, in develop, and in the read-only preview.

The tag is honoured as part of *reading the file*, at the same standing
as a RAW's masked-photosite crop, never as an edit. It lives as a
baseline on Framing rather than as a starting value for quarter_turns,
which is what keeps four things true: a sideways file opens unmodified,
reset returns it to upright rather than to the sensor's scan order, its
sidecar stays empty, and the rotate button still moves the image 90°
whatever the file underneath it says.

Framing::effective composes the baseline with the user's own turns
through the group law rather than by adding turns and OR-ing flags. The
naive version gets one case wrong — an odd baseline turn plus a user
mirror — and gets it wrong quietly, because the result is still a
plausible orientation. The composition collapses to a single
permutation, so obeying the tag costs nothing per pixel.

dr_decode::orientation is a header-only IFD walk, separate from
metadata() for the reason the entry points are separate at all: the grid
asks once per cell and must not build a rawler decoder to get one tag.
CR3 and RAF fall back to the full read, being neither TIFF nor JPEG.

Written down as FR-DEV-3h.

Known gap: thumbnails cached before this stay sideways. The store is
keyed by file and size, and its shards sync — invalidating them would
have every client re-download 25 MB a shard, which is not this commit's
call to make.

dtourolleandClaude Opus 5 03326242a1 Make the CI checks say what they mean, and format the workspace
Build and test / Desktop (Linux) (push) Successful in 1h23m26s
Build and test / Android (aarch64) (push) Failing after 2s
Build and test / Layer separation (push) Successful in 50s
Traceability / Requirement traces (push) Failing after 1m9s
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.

dtourolle 9f5e9955d5 Add sidecar serialisation for the edit graph
Sidecars are the only thing in the trust path: the catalog can be rebuilt
from them, so they carry the edit graph and its version in a form that
survives a schema change.
