Crate atune_gui 

atune_gui — an egui/eframe study-visualization GUI for atune (M6.5).

A read-only rendering layer over atune’s existing StudyReader / StudyView APIs — one crate, two entry points:

• Native (run_native): a desktop window ([eframe::run_native] on the glow/OpenGL backend) that opens the bundled demo, or a study loaded from a storage spec through the facade’s open_storage_read_only.
• Wasm (start_gallery, compiled only for wasm32-unknown-unknown and called by the atune_gui_gallery browser binary): the same app mounted in the browser on glow → WebGL2, reading the embedded deterministic fixture gallery. The library itself registers no start hook, so linking it never starts a second app (D88). It depends on atune_core plus the facade’s wasm-clean importance and diagnose features only — no system, no faer, no rusqlite — so it needs (and CI runs) its own wasm gate.

Every chart’s data→geometry is a pure function in the geometry module, unit tested with no window and no GPU (the atune report inline-SVG and atune top render_into precedent); the app shell only maps that geometry onto the screen. egui/eframe are confined entirely to this crate and never reach atune_core (docs/design/03-architecture.md §1).

The views, in the docs/09 §15 priority order: optimization history + running trials; per-seed band curves (the unique multi-seed view); parallel coordinates; PED-ANOVA parameter importance; the Pareto front; the PBT lineage tree (the unique fork-genealogy view); slice plots; open-search-space bounds over time; and sampler-independent findings. Each maps to an existing read API — see the geometry submodules.

Structs

StudyObservation

A read-only observation of one study in the viewer’s display model.

Functions

run_native

Runs the native desktop viewer until the window is closed.
