High-signal, low-noise architecture essays. https://roddcode.com en-us Mon, 19 Oct 2026 07:26:32 GMT The LLM doesn't know what's true. It knows what sounds right. Deterministic architecture is the only way to put AI in production without hallucinating money, appointments, or promises the system can't keep. https://roddcode.com/writing/db-fat-llm-light https://roddcode.com/writing/db-fat-llm-light Tue, 14 Jul 2026 00:00:00 GMT I built the same FSM four times for four different projects. The fourth version became reactive-fsm — a zero-dependency library for controlling LLM tool access in production. https://roddcode.com/writing/fourth-time-fsm-library https://roddcode.com/writing/fourth-time-fsm-library Tue, 09 Jun 2026 00:00:00 GMT I deleted a user from AD at 18. Almost cost a company its tax audit trail. The problem wasn't the delete — it was that nobody in the room understood what the data meant. https://roddcode.com/writing/domain-context-before-production-access https://roddcode.com/writing/domain-context-before-production-access Thu, 04 Jun 2026 00:00:00 GMT External APIs fail.
