A technical notebook for readable meaning.
SystemCtrl explores the relationship between actions, states and the feedback used to describe them.
The focus
The notes separate intention, request and observation so an interface or technical record can make a clearer statement.
The material is a general framework for discussion rather than a product specification.
The diagrams
The loop and state example are original teaching material. They do not describe a live system or claim a measured outcome.
Use the actual sources and responsibilities of the system you are examining.
The language
A label is useful when its meaning and supporting signal can be explained. Keep acknowledgement and completion distinct where they answer different questions.
The vocabulary should help the reader understand what is known and what remains open.
Using the guide
Begin with one action and its available feedback. Trace each important statement to its source.
For specialised engineering requirements, use the relevant documentation and appropriate expertise.
