// ─────────────────────────────────────────────────────────────────────────────
// Organ: /graph — the Spatial Cognitive Palace's flagship memory graph.
//
// This route's DEFAULT renderer (wherever WebGPU exists — verified live in this
// ANGLE/Playwright setup, adapter resolves OK) is the raw-WebGPU living memory
// FIELD (ObservatoryStage, chrome="none"), riding the REAL /api/graph payload.
// A one-click "Classic" toggle swaps in the Three.js inspector; the field is
// what ships as the front door, so this spec proves the FIELD.
//
// The 7-point organ contract this asserts (points 1–5, the organ-specific proof
// beyond all-routes-smoke):
//   1. REACHABLE      — /dashboard/graph mounts a canvas.
//   2. REAL DATA      — the API returns real memories AND the organ consumes
//                       them: the stats pill reports the same non-zero node/edge
//                       counts, and a canvas pick opens a REAL Memory Detail
//                       panel (onpick → api.memories.get on a real node id).
//   3. ALIVE          — the field animates (pixels change frame-to-frame).
//   4. CRASH-FREE     — a 6-point in-canvas click grid + a hover fire with zero
//                       page/WebGPU errors, and the field STILL renders after.
//   5. HONEST EMPTY   — asserted by reasoning over the +page / ObservatoryStage
//                       empty branch ("NO MEMORIES IN FIELD" on the void, never
//                       fake data / never a black errored surface). See NOTE.
//
// NOTE (point 5): the real brain has 1285 memories, so the empty branch cannot
// be driven live without mutating the DB. It is verified statically: both
// src/routes/(app)/graph/+page.svelte (EMPTY / OFFLINE / error branches) and
// src/lib/observatory/ObservatoryStage.svelte (`nodeCount === 0` → calm
// "NO MEMORIES IN FIELD", plus distinct loading/error text) render honest,
// non-fake, non-black states with no "Live" badge over mock data.
