dtourolle	6b99f67f47	Develop a mask layer's film on its own settings ... A layer offered the film's sliders and they moved nothing: its copy of the node was never given the stock, so it stayed inactive. Film now works in a layer the way the other adjustments do, as offsets to the photograph's settings, but blended as settings rather than as results, since a film is a rendering and cross-fading two developments is not what a region on a pushed film looks like. - dr-film bakes no slider. Exposure is a gain in the shader; push interpolates the stock's measured processes, one curve row each; the print is split at the paper's log exposure, so print exposure is an addition between two lookups and exact at any setting. The enlarger stays balanced at the photograph's exposure. - film_sim reads all four settings as uniforms, format one-hot over a grain count per format, so every uniform is linear in what it does. - Operation::blends_settings lets the composer average each overlapping layer's uniforms with the global ones by mask weight, the global setting taking whatever weight the layers leave, and run the fragment once. Three layers at full weight give the mean of their settings. - The stock picker is hidden on a layer. Only the photograph's exposure re-solves the print balance; push, print exposure and format need no rebake at all now.	2026-09-26 23:29:13 -04:00
dtourolle	84fade99ec	Put the developer docs under docs/dev and index the folder for users first ... docs/ had 26 developer documents flat beside the manual, and the two audiences are very differently sized: most readers want the manual and the gesture reference, a few want the register, the designs and the measurements. The manual and gestures.md stay at the top; everything for someone changing the code moves to docs/dev/, and the two documents that name their own successors — the v0.1 milestone and the UI-refinement plan — go to docs/dev/archive/ rather than being deleted, since both are still cited. docs/README.md is the index, users first. Every reference follows: code comments, Cargo manifests, the workflows, the pre-commit hook, the bench and traceability tools (which locate the repo root by docs/dev/requirements.md now), packaging, the Docker READMEs, CLAUDE.md, CONTRIBUTING.md and the README. The matrix links one level deeper and is regenerated. Links out of the moved documents into the tree gain a level; a link checker over every Markdown file finds none broken.	2026-09-20 21:16:03 +02:00
dtourolleandClaude Opus 5	2c56729354	Read a descriptor's variants without taking them ... Two agents worked in parallel and neither could see this. The frame-budget instrument matches `ParamKind::Enum { variants }` by value, which was free when a descriptor was `&'static` and everything in it was borrowed for the life of the program. Descriptors are owned now — a declaration parsed at run time cannot hand out a `&'static` — so `variants` is a `Vec` and the arm was moving out of a shared reference. Bound by reference instead. The arm only ever reads the length. The kind of conflict that survives a clean textual merge: git had nothing to report, and the two changes are only incompatible once they are in the same tree.

dtourolleandClaude Opus 5	7235972ca4	Measure what a frame costs, so FR-DSP-2 is decided by numbers ... `docs/display-and-extension.md` §2 fixes a decision rule in advance: if the 99th percentile of a frame sits inside 16 ms, tiled computation is rewritten as a scheduling concern for export rather than built on the interactive path. Nothing in the tree could answer that, so the rule had nothing to act on. This is the instrument. It renders a 60 MP synthetic source through the real `render_detailed` at three viewport sizes and four chain lengths, fit and zoomed to 1:1, and reports nearest-rank percentiles rather than means — a slider drag is judged by its worst frame. Three things it does that a simpler timer would not: - It separates the fused pass from the neighbourhood stage. "Every operation active" mixes one dispatch together with a chain of convolutions, and §2's question is about the first of those. `point` is every operation that contributes a fragment to the fused shader; `all` adds the four with kernels, and M3 times those alone by moving only a detail parameter so `render_detailed`'s colour reuse skips the fused dispatch. The reuse is reported rather than assumed — the `colour` column counts fused dispatches and must be zero for an M3 row to mean what it says. - It times the CPU half separately. Composition runs per frame in `DevelopSession::render`, so it is inside the budget whether or not anyone has looked at it, and if shader assembly were the expensive half then no tile scheduler could help. - It builds the "every operation" chain from `EditGraph::capabilities` rather than from a list, so declaring a new node does not quietly turn that row into a shorter chain wearing a longer chain's label.
