+## Description
+
+<!-- SECTION:DESCRIPTION:BEGIN -->
+Implemented a mathematical framework for visualizing how constraints propagate through decision pipelines. Each decision point creates a "possibility cone" - a light-cone-like structure representing reachable futures. Subsequent constraints act as apertures that narrow these cones.
+
+Key components:
+- types.ts: Core type definitions (SpacePoint, PossibilityCone, ConeConstraint, ConeIntersection, etc.)
+- geometry.ts: Vector operations, cone math, conic sections, intersection algorithms
+- pipeline.ts: ConstraintPipelineManager for constraint propagation through stages
+- optimization.ts: PathOptimizer with A*, Dijkstra, gradient descent, simulated annealing
+- visualization.ts: Rendering helpers for 2D/3D projections, SVG paths, canvas rendering
+
+Features:
+- N-dimensional possibility space with configurable dimensions
+- Constraint pipeline with stages and dependency analysis
+- Multiple constraint surface types (hyperplane, sphere, cone, custom)
+- Value-weighted path optimization through constrained space
+- Waist detection (bottleneck finding)
+- Caustic point detection (convergence analysis)
+- Animation helpers for cone narrowing visualization
