Run a node declaration without compiling it
`ops/*.yaml` plus `build.rs` has been the class-1 plugin format since the declarative nodes landed — it was simply resolved at build time. Nothing about a declaration requires the compiler: everything it produces is data plus a WGSL string, and the composer already assembles WGSL at run time from whatever operations are active. So this is not a new mechanism. It is the existing one, loaded later (FR-PLG-2). `DeclaredOp` implements `Operation` from an owned `Declaration` — one interpreter over many declarations, where `build.rs` emits generated code per node. The generated path stays, as FR-PLG-2 says it should: a generated `match` is faster than an interpreted one, the built-ins' declared `tests:` have to run under `cargo test`, and generated source is inspectable in a way an interpreter's state is not. **The reader is now one file, read by both.** `src/declared/decl.rs` and `src/declared/expr.rs` are `#[path]`-included by `build.rs` as well as being modules of the crate, and they produce a neutral `Declaration` that names no Rust type. The build script's job is reduced to *rendering* that declaration as Rust; `DeclaredOp` converts the same declaration into descriptors and `Expr::eval` walks the same tree the renderer writes out. There is one grammar, one set of validations and one set of error messages, so "a plugin is the same kind of thing as a built-in" is structural rather than aspirational. What remains genuinely written twice is the pair of backends — an arithmetic node rendered as Rust here and evaluated there — and that is what the parity test stands between. `tests/declared_parity.rs` parses every built-in declaration at run time and asserts the composed WGSL is byte-for-byte what the generated implementation produces, with the uniform block bit-for-bit identical, at both ends of every parameter's range and at four interior points; then again over the whole develop chain with the declared nodes swapped in, which is what covers uniform slot ordering and helper de-duplication between operations. A third test asserts the declared and hand-written nodes partition `ops/` between them, so coverage cannot shrink silently. Bit-for-bit rather than within a tolerance, because a tolerance is where a real divergence hides. The one thing that had to be got right for that to hold is number literals: `expr::as_f32` rounds a decimal exactly once, through the same shortest-round-trip text the compiler is handed, rather than rounding an `f64` a second time. Not in scope, and deliberately untagged: load-time WGSL validation (FR-PLG-11), id namespacing, a plugin directory read at startup, and pass nodes (FR-PLG-2a). Those are separate work, and tagging them from here would be the overstatement the spec's own §7 warns about. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> |

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.

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.

Let an operation say what it is about, so the panel can group without naming
Tool tabs need a taxonomy, and the taxonomy was the problem: a table in `ui/` mapping operation to tab breaks FR-DEV-3a, and a `group:` field risks what `ui-refinement.md` condemned `starts-group` for — the core deciding where the panel draws things. `Attribute` threads the needle. It says what an operation *is* — tone, colour, detail, optics, geometry, effect — which is the same category as `ParamKind` and squarely on the core's side of ARCH §4.3a's line. What is drawn, where it sits and whether it is visible stay the frontend's. There is no attribute for "the third tab", the enum's order is declaration order rather than screen order, and a frontend may render these as tabs, as headings, or ignore them. The payoff is that a tab strip can be *derived*: the groups are the attributes present in the capability list, so the interface names no operation and needs no table to keep in step. An operation joins the right group by declaring what it is, which is the one thing its author is well placed to say. Plural, because the tone curve is genuinely both — an RGB curve is tonal and the per-channel curves are chromatic, and filing it under one would hide it from half the people looking for it. Required and non-empty, enforced in `build.rs`, and the failure was checked by removing the line rather than assumed. An operation with no attribute is invisible to a panel that groups by them; a build that stops costs ten seconds, a control nobody can find costs more. The vocabulary is closed for the same reason: a typo would otherwise invent a category holding exactly one operation, which looks like a deliberate one until somebody counts. Six tests over the real chain, including the hand-written operations that `build.rs` never sees and so cannot check. |

Let a declared node ask for a widget, and write down how
Two gaps in the control vocabulary, both found by reading back what

Give the controls a vocabulary, and let a node ask for one
widgets.slint set the rule — screens consume components, and a bare `Theme.*` at a call site means a component is missing — and it set it for chrome only. The controls never got the same treatment, so they were written wherever they were first needed and copied from there. **The slider was private to the develop panel.** `SliderTrack`, with the fifty-line preamble explaining how it wrests a drag away from a Flickable, lived inside adjust.slint and no other screen could reach it. It shows: export quality is a 1-to-100 value, and the settings page offered a free-text box for it, with the range written in a hint and enforced nowhere. `to-float()` answers 0 for anything it cannot parse, so a typo saved a quality of 0 and the page displayed the 0 back as though it had been asked for. The tick-box was written twice, in launch.slint and settings.slint, from the same 18px box and the same handler; the second carried a comment deferring the lift until a third caller appeared. The label-and-hint header was written three times inside settings.slint alone. controls.slint is the input layer beside widgets.slint's chrome layer, and the constraint that makes it reusable is that **nothing in it knows about `ParamRow`** — that struct is the develop panel's flattening of the capability model, and a control that imported it could only ever be used by the develop panel. The primitives take plain numbers; the ParamRow-shaped wrappers stay in the panel that owns the model. 658 lines came out of the three screens. `SliderRow` is the slider-plus-number-box ARCH §4.3 names as the pointer presentation of a bounded scalar, and quality is its first adopter. It commits on gesture end rather than on every movement, because the settings page saves to disk on change and a two-second drag is a couple of hundred writes where a text field committed once. The develop panel keeps the live stream — that is what its pipeline is for — so `SliderTrack` now reports both. **The other half is the descriptor.** FR-DEV-3a and ARCH §4.3a already specify more than was built: an ordered preference list of widgets rather than one, the demands a widget makes, and kinds beyond scalar and bool. - `Presentation.widgets` is now a list, walked by `choose`, falling back to plain sliders. Falling off the end is not an error, and there is a test asserting an operation asking only for an unimplemented widget still yields one control per parameter. - `WidgetDemand` carries what a widget inherently needs — two-dimensional dragging, precise pointing — and no pixels, breakpoints or platform names. - `WidgetKind` grows to the specified set. There is deliberately no `Colour` *kind*: a colour is three numbers, and a value type that is not an `f32` would reach through the graph, the uniform block and the sidecar format to buy what `ColourWheel` over three scalars already describes. Every widget here is a hint over ordinary scalars, which is what keeps the fallback honest. - `ParamKind::Enum` is the one new shape, and it fits because a variant index is exact in binary32. `kind: enum` with a `variants:` list works in `ops/*.yaml`, so a node declaring one gets a segmented control with no UI file edited — which is the promise ops/mod.rs already makes. The panel's dispatch was duplicated: a lone parameter and a grouped one each wrote out their own list of kinds, so `enum` would have had to be added twice and a kind added to one would appear or vanish depending on how many parameters its operation happened to declare. `ParamControl` is now the only such chain. `rows_from` is free-standing rather than a method, which is what lets the FR-DEV-3c acceptance test requirements.md asks for actually be written: an operation the frontend has never heard of, appearing in a generated panel, with no GPU in sight.

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%. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> |

Say what the application is doing, in one bar and one list
Every background job reported into a window property of its own — library-thumbs-done, library-pin-total, library-syncing — which only the grid ever read. A pin download that outlived the view it was started from drew nothing at all once the user opened an image, and there was no answer anywhere to "what is this busy with", because the answer was spread across eight properties nothing collected. They report to one register now (ui/dr-ui/src/activity.rs). It publishes an aggregate, which draws a three-pixel bar across the top of the shell in every view, and a row per job, which the settings page lists: scans, thumbnail batches, pin and open downloads, sidecar uploads, the sync and the trash. Failures stay on the list until they are cleared; routine successes do not, or a scroll would bury them. The handle removes a still-running job when it drops, so a worker that dies mid-transfer takes its row with it rather than leaving the bar sweeping for the rest of the session. Also carries in-flight work from a parallel session — the drawn icon set and the dr-pipeline ops split. dr-pipeline's build script does not compile at this commit; ui/dr-ui does, with clippy clean and its tests passing.
