What it is

A decision-oriented field-guide series built around observable state, alternatives, gain, loss, footprint, risk, reversibility, decision and documentation.

What it is not

Not an encyclopedic manual, artifact catalog, command cheat sheet, tool-specific handbook or general theory course.

Series principle

A reversible action buys options. An irreversible action spends them.

Website role

The web companion maintains registry metadata, updates, references and state-based navigation without replacing the stable printed guide.
