VeritasChain is an open specification for evidence-based causal intelligence that enables AI systems to trace the relationships between decisions, laws, economic changes, technological developments, and historical events. It provides a modular framework for understanding why outcomes occur by connecting verified evidence, long-term timelines, and explainable causal analysis across industries and institutions. https://roxanneardary.com/veritaschain/

Chainly is an open-source AI-powered data flow intelligence system that traces what happens to user data after login events across the web. It builds evidence-based graphs of how information moves between first-party services, third-party vendors, and data brokers, revealing real-world data sharing that is often hidden behind privacy policies. By combining network tracing, graph analysis, and AI-driven entity resolution, Chainly turns invisible post-login data propagation into a transparent, auditable system. https://roxanneardary.com/chainly/

The Foundation for Deterministic Computing (FDC) is an open standards initiative dedicated to building reproducible, auditable, and human-governed computing systems. It defines modular specifications for deterministic execution, verifiable intelligence, structured knowledge, and transparent decision-making. The foundation provides a framework for ensuring that computational systems operate with consistency, traceability, and accountability across all layers of software and intelligent infrastructure. https://roxanneardary.com/foundation-for-deterministic-computing/

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/

ClearSignal is an open-source platform that maps telecom companies, infrastructure, ownership hierarchies, board members, regulatory filings, financials, and network coverage worldwide. It provides researchers, regulators, and the public with a transparent, interactive, and verifiable database to study networks, corporate structures, and assets. https://roxanneardary.com/clearsignal/

SignalTruth is an open-source, AGPL 3.0+ commercial real estate intelligence system that transforms fragmented public records into a structured, confidence-scored property graph. It integrates ownership history, market data, legal frameworks, and data completeness analysis into a unified, event-driven intelligence layer. Built for transparency and auditability, SignalTruth provides traceable, source-backed insights into real estate assets, their ownership structures, and regulatory context. https://roxanneardary.com/signaltruth

ClaimScout is an open-source AI platform that monitors code repositories, social media, and websites to detect potential copyright infringements. It automatically collects evidence, analyzes content, checks license compliance, and generates DMCA-ready reports, helping creators protect their intellectual property with intelligence and precision. https://roxanneardary.com/claimscout/

ARCA is a per-user provenance and originality ledger that tracks digital content across a creator’s personal history to determine whether each new post is genuinely novel, meaningfully contributed, and eligible for monetization. It combines timestamped archival records, content fingerprinting, behavioral authenticity scoring, and a transparent pre-submission evaluation system to ensure users always understand the originality and payout status of their content before publishing. https://roxanneardary.com/arca/

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/

The Open Source Observability Distribution

Rust implementation of GitLab's observability library (LabKit) - logging, metrics, tracing, correlation IDs

strace is a diagnostic, debugging and instructional userspace utility for Linux

Local testing for OpenTelemetry collector and Jaeger setup.

Download files from an S3 bucket via an API Gateway endpoint. API Gateway is secured using a Lambda Authorizer. The architecture also incorporates OpenTelemetry tracing.

A starter template for observable high-performance web services.

RV monitor automata models powered by eBPF tracing

Custom raytracing shader in HLSL implemented in Unity. It implements basic lighting physics : reflection and refraction. It works on Unity lightweight render pipeline, so the algorithm is iterative.

Color tracking with OpenCV and Qt Framework

Zipkin is a distributed tracing system

Flowdar is an extensively documented toolset for understanding how computer programs work. In particular, Flowdar helps understand the flow of control and data, and understand resource usage by the application.
