Variable Monitoring with Declarative Interfaces
summary
Code for a declarative builder-pattern API that wires hundreds of signal monitors into a pub/sub system is available at https github com nfogh monitoring and demonstrates concrete choices: conditions become composable conditions and handlers (callables wrapped to allow && || !), handlers do immediate or delayed alarm activation, and the framework avoids brittle inheritance while improving readability and scalability. The implementation is usable but unfinished around dynamic parameter subscriptions — the repo is a playground not a drop‑in product.
