Technical Companions

Draft — This content has not been approved for publication.

These are technical companion cards — deep-dive references for agents, editors, and researchers who need mathematical foundations, implementation details, and formal definitions beyond what the concise curated index provides. They are not replacements for the index cards; each companion links back to its corresponding summary.

All companion cards use KaTeX-rendered mathematics following the Math Rendering Guide and the formal-definition template (Variables, Domain, Assumptions, Meaning, Source) for key equations.
