Systems Engineering from First Principles
Part 1 — First Principles
Establishes the foundational reasoning framework — building mental models for system architecture and design from first principles rather than inherited convention.
Part 2 — Failure Modes
Covers the failure modes that affect software systems and the questions engineers should ask to anticipate and prevent them.
Reflection Modeling: An AI Framework for Personalizing Interactivity
A framework for capturing behavioral signals — clicks, pauses, hesitations — and modeling them into a continuously updating reflection of who each person is and what they want. Rather than starting from "what do we want this person to do," the system starts from "who is this person and what do they want," then aligns accordingly. Designed privacy-first: the person retains their own behavioral model and the system maintains only anonymous, aggregate intelligence.
A clinical intake agent that guides users through a symptom questionnaire and surfaces supplement recommendations backed by PubMed citations. Built on a supplement knowledge graph and iDISK, with a privacy-preserving session model — no conversation data is stored.
Infrastructure-as-code patterns and examples from real-world AWS deployments.
Fraud Filter
A community trust network for AI agent payment endpoints. Downloads nightly satisfaction scores, verifies endpoints before transactions, and submits anonymous outcome reports. Endpoint URLs are SHA-256 hashed; amounts are bucketed into ranges — no transaction details leave the machine.
Spend Ledger
A tamper-evident local ledger that tracks payments made through OpenClaw wallet tools. Detects payments via hook integration, records them in a hash-chained JSONL log, and surfaces spending history through a localhost-only dashboard. Includes loop detection and chain integrity verification.
An EHR and patient portal for complementary medicine practitioners. Features customizable SOAP notes, treatment and billing code libraries, superbill generation, and patient-facing iOS/Android apps — built for acupuncturists and CAM providers underserved by Western-medicine EHR systems.
