Spatial Dependency Engine
Spatial systems, derived from requirements.
Chalice.Systems is the workspace for modeling spatial systems of any kind - buildings, vessels, vehicles, campuses, and more - starting with intent, evidence, and dependencies before geometry is earned.
Dependency-first
SpatialDE resolves what must exist, why it must exist, and what blocks the next layer - before coordinates appear.
Provenance-aware
Values may be owner-selected, derived, reference evidence, or legitimately unresolved. HOLD and null are valid outputs.
Model over scene
The structured domain model is authoritative. Any future 3D view is a projection of earned spatial state - not an independent source of truth.
Product hierarchy
Chalice.Systems → product / workspace / UI SpatialDE → spatial dependency engine System → domain knowledge (Warehouse, Vessel, Vehicle, …) Project → one modeled spatial instance
Not limited to real estate. Model warehouses, homes, apartments, cruise ships, vehicles, campuses, and other spatial systems - each defined by domain knowledge, not by a single building type.
