IFC Model Author

This is an orchestration skill. It defines the order in which an IFC model is built and names the syntax, impl and errors skill that owns each step. It does not re-teach those skills: it sequences them.

ALWAYS author an IFC model in dependency order: a step depends on every step above it. NEVER add an element before the project skeleton (project, units, contexts, spatial tree) exists, because an element with no spatial parent and no representation context is invisible to every downstream consumer.
