Curated insights and technical field notes on Fraud.
Current note
The newest published argument and its visual artifact lead the page.
Read the noteEditorial posture
The library is organized around decisions that keep recurring in payment architecture, AI systems, and Doric product work. New notes lead by publish date, while topic lanes connect related arguments without turning the index into an archive wall.
Decision frame
Recommendation, rejected paths, and the operating proof behind the call.
Visual proof
Diagrams and original artifacts stay near the argument they explain.
Source posture
Public claims stay tied to released work or cited material.
Instant rails stripped out the friction that quietly prevented massive losses - and authorized push payment fraud walked straight through the gap. Once the money hits the rail it is gone, and multi-factor authentication cannot help when the victim authorizes the payment themselves.
Lead essay
The current Doric argument leads the index ahead of the chronological archive.
