Explanation

Explanation is the acquisition + cognition quadrant: the wider, reflective view. It is where the project answers why this and not that? — admitting opinion, weighing alternatives, and connecting current design choices back to the constraints they were chosen against. The pages here are meant to be read, not consulted. They have a thesis; they argue for it.

What explanation is not. It does not give direct instruction (that is How-to) and does not catalogue surface area (that is Reference). Step-by-step belongs in Tutorials. If you find yourself reaching for a procedure or an exhaustive list, you have drifted out of this quadrant.

• Why mforth — the project-level thesis: REPL ↔ mlog equivalence as the load-bearing idea.
• Forth, the mental model — the Forth-language sub-thesis: composition over abstraction, factoring as stack discipline.
