Structured Delegation: Governing AI in Long-Lived Codebases
A governance framework for tech leads, founders, and technical solopreneurs building long-lived systems in an AI-accelerated environment. This guide provides a structural decision model for when humans must anchor architectural work, when AI can safely draft bounded changes, and how to enforce behavioral guarantees during cross-cutting refactors. Includes the change-classification framework, refactor governance lane, validation criteria beyond green tests, and operational delegation rules designed to prevent architectural drift, token burn, and rewrite cycles.
Agentic AI, AT Fields, and Digital Telomere Decay
A technical deep-dive into the 2027 inflection point of Agentic AI. This analysis introduces the concept of 'Digital Telomere Decay' and provides a strategic framework for building 'AT Fields'—architectural constraints that preserve institutional sovereignty in a probabilistic age.
Boat Buying: A Practical Guide for Knowledge Workers
Most boating content sells the fantasy. This document focuses on the decisions that lock people into bad outcomes. If you’re considering living aboard while continuing to do knowledge work — not switching careers to full-time maintenance — this guide helps you avoid the two mistakes that cost the most money and time.
Electric Displacement Speed on Large Hulls
A physics-grounded analysis of electric propulsion limits on large displacement hulls, calibrated against real on-water GPS data from a ~24-ton vessel. No hype, no despair — just honest bounds. Includes the full Markdown write-up (ElectricDispSpeed.md), a formatted PDF (arpeggio-calc-report.pdf), and supporting figures, packaged as a single ZIP.
