Engineering Notes — Artur Panek https://artur.panek.tech/notes/ 2026-10-06T00:00:00Z Artur Panek https://artur.panek.tech/ A config file does not tell you what an AI agent is actually running https://artur.panek.tech/notes/ai-agent-config-vs-runtime/ 2026-10-06T00:00:00Z 2026-10-06T00:00:00Z Why AI-agent configuration, runtime resolution and live observations are different evidence layers — and why a verifier should keep them separate. Why a route dump does not explain a Linux routing decision https://artur.panek.tech/notes/linux-routing-kernel-evidence/ 2026-10-06T00:00:00Z 2026-10-06T00:00:00Z Why Linux route tables alone cannot establish the path selected for a flow, and why kernel-backed lookups are better diagnostic evidence. Static dependencies and runtime causality are different questions in Home Assistant https://artur.panek.tech/notes/home-assistant-static-vs-runtime/ 2026-10-06T00:00:00Z 2026-10-06T00:00:00Z Why Home Assistant configuration dependency analysis and runtime incident reconstruction need separate evidence models. What Postfix status=sent actually proves https://artur.panek.tech/notes/postfix-status-sent/ 2026-10-06T00:00:00Z 2026-10-06T00:00:00Z What Postfix status=sent means, why it is not proof of inbox placement, and how to stop a mail-delivery verdict at the last confirmed stage.
