Milestone exit criteria (summary)

M13 · PCG core (v0.3.0)

• [x] pcg/ layer: fields/sampling (isoline marching squares, heatmap, vectorField, streamlines), parametric/lattice/tiling, lSystem/fractal/recursiveTree/graphObject/cellularAutomaton, mapData/barChart/scatter/lineChart, operators (transformObject/repeatObject/instanceField/booleanOp/mapPoints/along)
• [x] Determinism via injected ctx.rng; depcruise pcg-headless-deps rule
• [x] 6 examples + pcg.test.ts (same seed reproducibility, marching squares, CA stepping, operator composition)

M14 · Full 3D (v0.4.0)

• [x] Transform3D/RuntimeState3D + 2D|3D snapshot/Player generalization; quaternions
• [x] Scene3D + registered Camera3D (orbit/dolly/zoom/lookAt/quaternion)
• [x] 3D factories (curve3D/polyline3D/meshObject/surface3D/pointCloud3D/axes3D/group3D) + 3D Create + marching-cubes
• [x] render-three/render-r3f 3D views + perspective/orbit + RenderedScene
• [x] 5 examples + 3D bounds/transform/camera/sampling/marching-cubes cases

M15 · Serialization / export / embed (v0.5.0)

• [x] serialize/: op-log + baked geometry + pristine initial values + signals + seed; golden frame hash per-frame equality
• [x] Phase-1 serialization debt resolved (easing/morph/call/reactive); share-url; SVG/frame hash; web-component; semantic layer + reduced-motion
• [x] 4 examples + serialize.test.ts (round-trip equality, golden frame hash, reduced-motion fallback)

M16 · Performance & big data (v0.6.0)

• [x] True GPU instancing (InstancedTrait→InstancedMesh); sampling memoize (provider layer)
• [x] Player track interval pruning (binary active window); Worker pure tasks (render-three/worker/, core stays DOM-free)
• [x] Performance budget benchmarks in CI (perf-budget.test.ts) + pnpm run bench
• [x] 3 examples (instanced-10k/large-pointcloud/worker-sampling)

M17 · Extensibility / plugins (v0.7.0)

• [x] extend/: generic Registry<K,V> + four descriptor types + Registries + globalRegistries
• [x] definePlugin/installPlugin + dispatch helpers (createRegisteredObject/runGenerator/selectRenderer)
• [x] Custom animations via global registry + injected resolver wiring (custom spec/compileSpec/StoryboardBuilder/customAnimation()), serialization covers custom
• [x] 3 examples (custom-object/custom-generator/webgpu-backend PoC) + extend.test.ts (10)

Known deviations / open items (non-blocking for v1.0)

• Derived objects / external bindings not in serialization round-trip (by design; live logic needs host re-wiring); baked objects lose interactive/parametric liveness (static geometry equivalent).
• GPU instancing per-instance reveal/picking not done (group opacity/fillProgress for whole fade); point cloud per-point coloring not done (monochrome glow).
• Worker subset is pure functions (resample/triangulate/marching-cubes/parse-svg-path); MathJax DOM steps stay on main thread; Worker construction is host responsibility (bundler-related).
• WebGPU backend is registry placeholder PoC (feature probe + selectRenderer selection + overlay display); real WebGPURenderer device wiring (via R3F <Canvas gl>) is next PoC step; scene still uses default WebGL.
• Object type registry currently serializes geometry via generic bake path (custom serialization hooks not done); complements trait model; descriptor mainly handles construction by name + tool discovery.
