Edge glyph (⟹ follows arrow) WITHDRAWN by owner after two live-rejected variants — CanvasEdge.type plumbing + ArrowGeom retained, differentiation approach still open (docs/vision-edge-glyph.md decision record). Keepers: regions.enabled "Background colors" compute off-switch (skips splat/blur/readback/blit), clusterLabelSize (default 14, topmost draw layer, screen-px) with Cluster labels toggle + size slider in the Regions section, dependency graying across the settings panels, physics panel reorder (general forces first, Depth anchor + conditionals last). Merged cleanly over master's coverage-chrome changes in graph-view.tsx (their gated fragment + the ungated GraphCoverageControl coexist); data/ scratch not carried (untracked, master's real render-settings.json picked up clusterLabelSize=14 via sanitizer fallback). Gates 488/488; live- verified: chrome intact, Background colors graying works, physics order, coverage panel opens (11 sessions).

/**
|
||
* The home knowledge-graph view (W4; vision §1 "Rendering (DECIDED)").
|
||
*
|
||
* ARCHITECTURE (2026-09-13, decided after the research pass —
|
||
* docs/research/graph-rendering.md, Option B): sigma.js is GONE. The
|
||
* renderer is now a hand-rolled single Canvas 2D (./graph-canvas.ts) —
|
||
* a DUMB DRAW FUNCTION over plain data with ONE requestAnimationFrame
|
||
* loop and a dirty flag. Everything that made the sigma era fragile is
|
||
* structurally impossible now: hulls cannot lag nodes (one loop, one
|
||
* camera, one frame), settings changes cannot shift anything (the
|
||
* camera lives in the renderer and no rebuild ever happens), and the
|
||
* per-camera-event full-canvas repaints (GPU spikes + coil whine) are
|
||
* gone (at most one draw per frame, and NO frame at all while idle).
|
||
*
|
||
* Layout fallback (ledger absent): ONE synchronous incrementalLayout
|
||
* pass (d3-force, core/layout.ts) inside a useEffect writes world-space
|
||
* x/y, then the positions are handed to the renderer as data. No layout
|
||
* animation ever starts; the only animation is the
|
||
* short hover fade, strictly bounded in time — idle CPU is zero (the
|
||
* loop schedules no rAF until something actually changes).
|
||
*
|
||
* The component's job is everything AROUND drawing: fetch + refetch the
|
||
* snapshot, run the layout, resolve theme colors to hex, filter via the
|
||
* search box, own the settings panel / detail card / import button /
|
||
* pipeline chips, and FEED the renderer (data, settings, visibility).
|
||
* The renderer's contract stays presentation-only — which is exactly
|
||
* what the upcoming playground and cluster-first layout work needs: a
|
||
* renderer that draws whatever data it is given, never questioning it.
|
||
*
|
||
* Visual semantics, all preserved verbatim from the sigma era:
|
||
* - Node labels (the short extractor-coined names) wrap under the
|
||
* node; one GLOBAL zoom gate fades them together (no per-node pop).
|
||
* - Hover: a soft glow halo in the node's own color at a constant
|
||
* radius, opacity cross-faded ~180ms with the name brightening on
|
||
* the same factor; the whole halo is hit-testable (picking pad).
|
||
* - Cluster hulls (vision §1): soft layered translucent fills + a
|
||
* dashed boundary per cluster, stable hue from the cluster id; the
|
||
* region label at the centroid fades in over the exact zoom span
|
||
* node labels fade out (THE single zoom control) — and is
|
||
* toggleable in the settings panel (hulls always draw).
|
||
* - The persisted labelZoom setting keeps sigma's camera-ratio
|
||
* convention (1 = fit zoom, SMALLER = zoomed in): labels until
|
||
* zoom 0.5x means labels appear once zoomed in past 2x fit.
|
||
* - Click a node -> the detail card anchored just below it (flipping
|
||
* above near the bottom edge); any camera move dismisses it.
|
||
* Clicking the empty stage closes it. Search filtering hides nodes
|
||
* (and their edges) from rendering, picking, hover, AND labels;
|
||
* an open card closes if its node is filtered out.
|
||
*
|
||
* Rendering settings (2026-09-13): the gear in the search panel reveals
|
||
* five sliders (node size, edge width, arrowhead length, label size, the
|
||
* zoom threshold) plus the cluster-labels checkbox. SERVER-persisted
|
||
* (data/render-settings.json via /api/graph/render-settings): loaded
|
||
* once after mount, saved debounced on every user change — one source
|
||
* of truth shared by every browser. The label-zoom slider is log-scaled
|
||
* (its useful band 0.25–0.5 sits mid-slider, not crammed at the left)
|
||
* and displays normalized units where the default 0.5 reads as "1×".
|
||
* Settings apply by just redrawing — no rebuild, no re-layout, and the
|
||
* camera never moves.
