facett roadmap — incoming components, guest wrappers, the rest

What's queued, grouped. Phase rule still holds: copy + fix in facett; cut the source over only for knut (quiescent), copy-only for nornir/znippy/osm.

Done (the uniformity + look pass)

The component-uniformity design set is now built:

• ✅ Capability model — FacetCaps (10 flags) + defaulted Facet surface; deck queries caps for its toolbar/shortcuts (2b5b68e). See adding-a-component.md.
• ✅ Uniform clipboard — Ctrl-C/X/V routed by the deck, gated on caps, deferring to focused TextEdits; shared rows_to_tsv (2b5b68e). See design/clipboard.md.
• ✅ Table copy — facett-table selectable rows → TSV copy (the highest-value ask), virtualized via egui_extras::TableBuilder (2b5b68e).
• ✅ Striking palettes — nordic_aurora/cyberpunk_neon/amber_crt/ deep_space/hugin_noir + the glow field + Theme::ALL/names/by_name enumeration (ce91f1f). See theming.md.
• ✅ Effects — easing, glow_rect/glow_text/shimmer/ParticleBurst, and the signature RavenSprite (bezier arc + ease-out-back perch + idle bob), glow-backend-only (ce91f1f). See effects.md.
• ✅ facett-form — FormView<T> over egui_form 0.8 + garde: validated fields, sections, dirty-tracking, submit/reset, JSON copy/paste (64c92d4). See components.md.

Remaining

• ✅ facett-card — DONE (ce91f1f.., migrated to Elm in 2ef3c25): YouTrack-style cards with a typed CardField grid and nestable sub-cards (recursive, collapsible), facett-card/src/lib.rs; tested (facett-card/src/tests.rs); demo-wired (facett-demo/src/lib.rs).
• ✅ facett-menu — DONE: context menus (context_menu), a CommandPalette overlay (Ctrl-K / Ctrl-Shift-P), and classic dropdown menu_bars, all sharing one Command set (facett-menu/src/lib.rs); demo- and testmatrix-wired (0bf5b21, facett-demo/tests/mega_matrix.rs).
• ✅ facett-plotters — DONE: five chart types beyond egui_plot — boxplot, candlestick, heatmap, ramp, treemap, violin (facett-plotters/src/), migrated to Elm in 9b427ce; demo-wired (facett-demo/src/data.rs, facett-demo/src/lib.rs).
• ✅ facett-pipeline glow-up — pipeline DAG brought up to the new look: themeable+resizable caps, theme-driven colours (Status::theme_color off accent/point/red), animated flowing edges (marching-ants edge_phase showing dataflow direction; with_speed), per-stage status glow (running pulse / done steady / failed red bloom via effects::glow_rect, status_glow), and throughput labels on edges (with_throughput). Back-compat: PipelineView::new/with_progress/counts unchanged (korp builds clean); animation with_animation(false) for still/headless. Example pipeline_demo animates under every palette.
• ✅ fx-deck-integration — DeckFx (palette override + glow toggle/speed), FacetDeck::palette_picker/set_palette/cycle_palette, and FacetDeck::send_raven(rect) (launches a RavenSprite to perch on any rect through the deck, drawn on a foreground layer). Strictly opt-in, off by default, cheap when off. Example deck_fx_demo. Pure phase/cycle math is unit tested (deckfx.rs).
• facett-flow — deferred: egui_xyflow is on egui 0.31, facett on 0.34 (see below + notes/egui-xyflow-eval.md).

Components to bring in

Guest wrappers (use best-in-class egui crates where we don't have our own)

Policy: thin Facet wrappers around good egui crates, added to the MEGA matrix. Candidates:

The egui bump — ✓ done (facett on 0.35, not 0.34)

facett's workspace egui / eframe / egui_extras went to 0.34 in 8c79c20 (Rounding→CornerRadius, rect_stroke StrokeKind), which unblocked the virtualized table and egui_plot. Corrected 2026-08-27: the workspace pin is now egui = "0.35" (Cargo.toml:25). Every "facett is on 0.34" above and below is one bump behind; they are left standing because the xyflow argument they make does not change — an 0.31 crate does not unify with 0.34 or with 0.35.

The two things the bump was for:

• egui_xyflow is still on egui 0.31 (two egui trees → Ui/Pos2 don't unify), so facett-flow waits for an xyflow release on facett's egui — the wrapper is written and works except the mismatch. Still true; there is no facett-flow crate in the tree.
• The wgpu kernel — ✅ LANDED, and this bullet was still calling it pending on 2026-08-27. It is facett-core/src/render/gpu/ (9 720 lines of Rust + 15 .wgsl shaders: cull, draw, pick, oit, taa, blur, colorgrade, msdf, sdf, particles, label_collide, label_draw, line, graphcloud, common), scaffolded in 2e55446a and grown since. The workspace pins wgpu = "29" with gles dropped from the default feature set, and facett-core/tests/webgl_free_law.rs red-fires if glow/khronos-egl re-enter any normal dependency graph — LAW 4 by construction, not by intention. ⚠ The link this bullet and step 4 carried, wgpu-plan.md, does not exist in .nornir/ and appears never to have been committed; a reader following it got a 404, which is how the bullet stayed "pending" while the lane shipped.

The historical decision was to do the bump as one bundled, GUI-verified pass (bump → xyflow → wgpu); the bump and the wgpu halves are done, xyflow remains.

Plan (mechanical):

1. ✓ Bump workspace egui/eframe/egui_extras → 0.34 (8c79c20), and since to 0.35. (knut's egui-snarl → 0.9 follows when knut is touched.)
2. ✓ Fix the breakage: Rounding → CornerRadius, rect_stroke StrokeKind. The headless matrix is the regression net — green matrix + sane vertex counts = components still render.
3. Add facett-flow wrapping egui_xyflow 0.4.3; add to the matrix. (waiting on an xyflow release on facett's egui — the one step here still open)
4. ✓ Land the wgpu kernel — done, facett-core/src/render/gpu/; see above.
5. ✓ The GUIs render on a machine with a GPU (oden, RTX 4090).

Arrow data viewer (scrolling)

facett-table → virtualized via egui_extras::TableBuilder (only visible rows built) + a facett-arrow adapter RecordBatch → rows, so a million-row Arrow batch scrolls at 60 fps. Pairs with facett-osm (already streams 6.3M pts/s).

Audio (future 🔊)

A facett-audio lane — sonify the data (ingest progress ticks, alert tones on a failed pipeline stage, a sweep as the map loads). Likely cpal/rodio behind a Facet-adjacent trait (fn audio(&self) -> AudioCue). Sketch only; revisit after the visual layers settle.

Themable + striking palettes ✓

Done — Theme + seven palettes (default/sci_fi/nordic_aurora/ cyberpunk_neon/amber_crt/deep_space/hugin_noir), the glow field, and the Theme::ALL/names/by_name enumeration; every component reads theme(ui); korp defaults to sci-fi (ce91f1f). The CPU effects (glow/raven/shimmer) ship glow-backend-only. Next: wire the theme picker + effects into FacetDeck (fx-deck-integration above), and true HDR bloom once wgpu lands (theming.md, effects.md).
