			== What a schema is ==
			A schema is an '''abstraction''' that defines meaning, structure, and constraints, '''independent of any particular file format or tool'''.

			A schema is:
			* Conceptual before it is representational
			* Declarative rather than procedural
			* Concerned with '''what is true''', not '''how it is produced'''

			A schema does '''not''' inherently belong to:
			* JSON
			* YAML
			* XML
			* IFC
			* FreeCAD
			* Revit
			* Any specific software system

			Those are merely '''serialization formats''' or '''containers''' used to express the schema.

			== Role of the compiler ==
			The purpose of a compiler is to '''translate a schema into a target representation'''.

			A compiler:
			* Interprets the schema’s meaning and constraints
			* Resolves ambiguities and degrees of freedom
			* Applies deterministic construction rules
			* Emits a concrete artifact in a target domain

			Examples of compiler targets include:
			* FreeCAD geometry
			* IFC models
			* Permit drawings
			* Bills of materials
			* Installation instructions
			* Inspection checklists

			== Key separation ==
			* The '''schema''' defines intent and truth
			* The '''compiler''' defines execution
			* The '''output''' is disposable and regenerable

			This separation is what enables:
			* Lossless regeneration
			* Automation at scale
			* Tool independence
			* Safe use of AI

			== Summary ==
			A schema is a tool-independent abstraction of meaning and constraints.

			A compiler is the mechanism that translates that abstraction into a specific, concrete output.

A schema is a formal, machine-readable contract that declares what exists, what it means, and what must be true—without saying how to build it

== A schema is not ==
A schema is '''not''' any of the following:

* Geometry
* Code
* Instructions
* Algorithms
* Drawings
* A script
* A model in FreeCAD

All of the above are '''derived artifacts''' — they are produced *from* a schema by compilers, generators, or humans, but they are not the schema itself.
