HAPI Obsidian Knowledge Base Index

Purpose

This vault is the foundation layer for the HAPI Project knowledge base. It consolidates the base business logic from the HAPI User Manual, the HAPI Quick Start Guide, project configuration files, and selected implementation notes.

The goal is to make the core HAPI rules reusable for:

Obsidian reading and navigation
ChatGPT discussions
Codex project context
PythonNet3 implementation
Future C# Civil 3D plugin migration

Source Priority

Priority	Source	Treatment
1	HAPI User Manual.pdf	Primary source for official workflow, terminology, Point Code logic, Style Code logic, and script families.
2	HAPI Quick Start Guide.pdf	Visual and explanatory supplement, especially for the Enhanced Point Code Framework.
3	User-confirmed corrections	Overrides the manual where explicitly confirmed.
4	FeatureCatalogue.json / GlobalConfiguration.json	Current executable configuration reference.
5	Old Markdown specifications	Implementation-facing notes, not automatically canonical business rules.

Confirmed Manual Corrections

Topic	Correct Project Rule
Shrink to Fit scoring	Use Minimum Perimeter, not minimum area. See Rectangle_Fitting_Rules.
