Definition #

Every operator choice is made by design or by default — there is no third option. Claims like “by experience,” “by intuition,” or “by what works” are fictions that collapse into by default.

Family #

Canon. Core principle. Input into all five fundamentals. Book-wide operating principle. Lives upstream of all five fundamentals.

Why Behind the Thinking #

The asymmetry is the teaching: Road 2 must be built (only one entry path: by design). Road 1 has two entry paths (by design and by default). The operator who is by-default on Road 1 never knew Road 2 existed as a build. The education move is showing them the build. The operator who chose Road 1 by design ran wrong math — the confrontation move. Without [By Design Or By Default] named, operators hide behind intuition and experience as cover for default behavior.

Placement #

Book-wide operating principle. Runs as test inside each road — exposes whether the operator chose it or drifted onto it.
