Software Projects
OiC.OS engine
2025–2026 — With Renée Menéndez. OiC.OS: executable formal specification of a national accounting system. Full stack from double-entry bookkeeping (Lawvere theory T_DEB) through quadruple-entry profunctor accounting (T_QEB) to Agent-Bank-Central-Bank hierarchies with coend aggregation.
