Dashboard search overhaul, viewer redesign & performance work#29
Merged
Conversation
Dashboard / search: - Facet-powered filters with live counts via /api/facets - New filters from existing metadata: manufacturer, CT phase, site, study year - URL-encoded, shareable/bookmarkable filtered cohorts + copy-link button - Pagination over results (16/page, 4x4) with prev/next, jump-to-page, and "Browse all" to page the full dataset; lazy-loaded thumbnails - Default grid = fullest-body scans, half tumor / half no-tumor - Accurate organ-class stat (derived from the viewer's label set) Viewer: - Refined dark UI (panels, sliders, segmented controls, checkboxes, chevrons) - Inline Organ Statistics panel (per-organ volume + mean HU via /api/mask-data) - Low-res-first volume loading with an HD toggle; measured download progress bar - Local-first volume loading with HuggingFace fallback - View-switch (MPR/Axial/Sag/Cor/3D) layout + camera fixes - 3D organ loader restored behind an error boundary; report-button feedback Upload: - Client-side pre-inference CT preview (NiiVue, lazy-loaded) Performance: - Route code-splitting (dashboard initial JS ~1.6MB -> ~93KB gzip) - Viewer-chunk prefetch on hover/idle Backend (additive, fallback-safe): - Low-res volume serving via ?res=low on get-main-nifti / get-segmentations - Cache-Control on volume responses - scripts/make_lowres.py batch job to generate low-res CT + mask copies

make_lowres.pyon the server (needs writable$PANTS_PATH/data+ disk headroom). Until then, everything serves full-res exactly as before.Testing
tsc -bclean; 32/32 Vitest tests pass (added unit tests for the search helpers); production build succeeds.metadata.xlsx, so volume/organ-stats/report features that need image data show graceful "unavailable" states locally and will populate on the JHU server.
