GovGraph is an open-source, modular system for mapping and analyzing public systems through structured data. It connects social media activity, campaign finance disclosures, and publicly available institutional information into a unified graph model, enabling transparent, reproducible analysis of how public-facing digital activity and documented financial data relate across platforms and agencies. https://roxanneardary.com/govgraph/

CommonsProtocol is an open-source civic transparency platform that provides a public, auditable infrastructure for political campaigns, governments, and civic organizations. It enables real-time visibility into donations, spending, and governance finances through a federated, append-only ledger system designed for accountability, trust, and public oversight. https://roxanneardary.com/commonsprotocol/

Altius Capital OS is a modular financial operating system that transforms jurisdictional rules, tax codes, and custody constraints into a deterministic computation framework. It models capital allocation across banking, treasury, and brokerage systems while incorporating federal and state tax logic through a versioned rule-graph architecture. The system is designed to produce transparent, auditable, and constraint-compliant capital structures, enabling users to evaluate financial strategies as structured, reproducible outputs rather than subjective advice. https://roxanneardary.com/altius-capital-os/

Vantor is a deterministic capital routing system that converts explicit user-defined financial intent into structured, rule-validated execution instructions. It uses AI solely as a natural language parser and enforces a strict no-withdrawal, no-inference architecture where all allocations, schedules, and transactions must be explicitly defined, validated, and executed through approved deposit-only financial rails. https://roxanneardary.com/vantor/

Ledger Watch is an open-source financial data infrastructure project that organizes publicly available market information—such as trades, SEC filings, corporate actions, and economic events—into a structured, verifiable system. It connects entities like individuals, companies, and institutions to market events through a transparent data model designed for analysis, research, and pattern discovery. The system emphasizes neutrality, reproducibility, and strict reliance on public, source-backed data rather than speculation or inferred intent. https://roxanneardary.com/ledgerwatch/
