MIDAS is an open platform for governing execution authority at decision surfaces across agents, AI systems, and enterprise workflows.

A long-form article introducing the Twin Test: a practical standard for high-stakes machine learning where models must show nearest “twin” examples, neighborhood tightness, mixed-vs-homogeneous evidence, and “no reliable twins” abstention. Argues similarity and evidence packets beat probability scores for trust and safety.

A long-form article and practical framework for designing machine learning systems that warn instead of decide. Covers regimes vs decimals, levers over labels, reversible alerts, anti-coercion UI patterns, auditability, and the “Warning Card” template, so ML preserves human agency while staying useful under uncertainty.

Longform article reframing abstention (reject option / selective prediction) as product design, not model weakness. Covers coverage as a KPI, calibration as a prerequisite, threshold selection under review capacity and risk, queue/UX design for human-in-the-loop workflows, and anti-patterns that break safety in production.

Turn-based control architectures

CFS (Cognitive Flow System) — a causal influence framework for modeling how decisions emerge in complex systems through structured causal constraints. DOI: https://doi.org/10.5281/zenodo.19142077 DOI: https://doi.org/10.5281/zenodo.19103972

Deterministic governance system for AI-driven marketing that separates diagnostics, human reasoning, and execution into strictly controlled layers.

Optimization-driven product selection for commercial buying decisions under budget and business constraints.

Responsibility Normalization Contract

This tool visualizes how thresholds, top-K limits, and review budgets remove candidates before human review. It informs threshold selection, review budget sizing, and top-K choice in constrained human review workflows.

Analytics and automation builder focused on turning operational data into practical decision tools. Background in commercial and retail planning, moving toward decision systems and analytics engineering.

A design framework for decision-centered automation, governance, and early misalignment detection.
