scenes.py aimed every press at window pixels, and the develop column had already moved under it: Compose now sits above Adjust, so the old exposure coordinate lands on a straighten slider. Every scene now names what it presses by its accessible label through the automation hook, places points on the photograph relative to the canvas, and opens its photographs by file name. Each starts from a known place and undoes what it did, so one can be recorded alone; the few that continue another's state name it, and running one runs that first into a scratch folder. Each scene also declares the pictures it makes and the sources they depend on. `record.sh --check` fails when the manual shows a picture no scene makes, or a scene makes one it does not show; it reads two files. `record.sh --changed` re-records the scenes whose sources, or own code, changed since the commit that last touched their pictures. record.sh builds with the automation feature, restores the library from DR_LIBRARY_SNAPSHOT, starts from a fresh profile and pins inference to the CPU; the launch screen is recorded from an empty profile of its own. Re-recorded with the ported scenes, and looked at frame by frame. What differs from the pictures they replace: - develop, presets, settings, local, compose, film, wb, light: the current develop column (Compose with Vertical and Horizontal above Adjust, the Label button), otherwise the same moments. - library pictures: the filter bar's colour-label chips; no collection left over from an earlier run in the sidebar; library-selection is the twelve alpine frames rather than eight of them and four New York ones. - library-rating rates two frames nobody had rated, so the stars are set and not cleared. - develop-zoom goes on past 1:1 with the wheel and ends on the file's pixels as hard-edged blocks. - repair covers a real mark on the road, with a size that fits it; film is shown on the Chinatown frame instead of the road. - panorama tries Perspective, Spherical and Cylindrical before filling. - launch, launch-folder and panorama-aligned came out byte-identical.
Documentation
Two audiences, two folders. Most people want the first table and never the second.
Using DarkRoom
| The manual | Every feature, pictured from the application itself — opening a library, rating and filing, developing, local masks, repair, film, panoramas, export |
| How it is driven | Every gesture and shortcut, by screen. Generated from the code, so it cannot describe one the application does not have |
The top-level README says what DarkRoom is, how to get it on each platform, and what is still missing.
Changing DarkRoom
Everything under dev/ is for someone working on the code. Start with
CONTRIBUTING.md, which says how to land a first change
without reading the rest.
The register and the record. What must be built, how it is built, and how far along it is.
| requirements.md | What the software must do — the numbered register, the decisions (D-numbers) and the spikes (S-numbers) |
| architecture.md | How it is built — crates, the GPU pipeline, the data model, sync |
| traceability.md | Generated: which requirement is claimed by which file. Never edited by hand |
| outstanding.md | What is specified and not built, and whether that is a decision or a gap |
| technical-debt.md | Compromises taken deliberately, each with the condition that retires it |
| code-health.md | What a contribution costs, per seam, measured |
Designs, one per subsystem. Each is the specification the code was built to, kept current as the code moved.
| catalog.md | The index, the library view, incremental scan, the job queue |
| storage.md | Storage backends: the seam a folder, a sync client and a Nextcloud account share |
| faces.md | Face detection, identity, clustering and the eye-state models |
| segmentation.md | How the application finds the regions a local mask snaps to |
| mask-editing.md | Painting, erasing and combining masks |
| spot-removal.md | Clone and heal as parameters in the edit graph |
| panorama.md | Alignment, projection, the chunked composite and the border fill |
| inference.md | The neural runtime and model chosen per device, with the measurements |
| display-and-extension.md | The display contract, and why the fused pipeline is already most of a plugin format |
| view-composition.md | A controller for the display layer |
| ui-navigation.md | Finding things in the interface once there are many |
Measurements. Numbers committed so a regression is a diff rather than a recollection.
| benchmarks.md | The per-commit suite: what it covers, what it does not, how to read a failure |
| bench-baseline.json | The committed numbers the suite checks against |
| frame-budget.md | What a frame costs on each device, and the decision those figures settled |
Platforms and distribution.
| distribution.md | Which channels v1 targets and what each one constrains |
| windows.md | The Windows installer, cross-built from the Linux CI |
| android-signing.md | Which key signs the APK, and keeping it |
Archive. Kept as the record of what was asked for, not as plans.
| milestone-v0.1.md | The first milestone, delivered 2026-08-30 and superseded |
| ui-refinement.md | How the interface should look; succeeded by ui-navigation.md |
Conventions
Two files here are generated and must not be edited by hand:
gestures.md and dev/traceability.md. Both come from
cargo run -p traceability and the pre-commit hook keeps them in step with
the tree. The manual's pictures are recorded by
tools/manual and live in LFS.
A design document links to the requirements it satisfies and to the code
that satisfies them. When the code moves, the link moves with it; a document
that has stopped being true goes to dev/archive/ with a note saying what
replaced it, rather than being deleted.
