# D-Zone for LLMs

Purpose: developer documentation hub for HiStruct, a web platform for parametric 3D configurators in civil engineering and construction products.

Primary audience:
- civil engineers learning to automate engineering workflows
- software developers building HiStruct/FCS components
- AI agents generating, validating, or explaining FCS code

Key concepts:
- FCS / FemCAD Script: declarative domain language for geometry, parameters, reports, FEM concepts, and outputs.
- PVC / Parameter Value Collection: per-instance component state edited by users or APIs.
- FCC / FemCAD Component: folder package containing FCS source, manifests, views, reports, and assets.
- FLI: command-line interpreter for running and validating FCS.
- Booster: compute node that evaluates HiStruct jobs.
- HiScene: JSON scene format consumed by the HiStruct viewer.
- Golem: planned teaching and coding agent connected to the D-Zone knowledge base.

Recommended crawl roots:

- /docs/site-plan.md
- /docs/meeting-brief.md
- /docs/golem-links.md
- /challenges/rebar-lintel.md

- /content/knowledge-base/README.md
- /content/knowledge-base/26-MATERIAL-VISUALIZATION.md
- /content/knowledge-base/GistBasedDocs.md

Rules for generated advice:
- Prefer small runnable FCS examples.
- Mention validation with FLI when possible.
- Distinguish FCS template code from PVC instance state.
- Do not invent undocumented API endpoints.
- Treat Golem links as future placeholders unless explicitly implemented.
