Practitioner onboarding is characterized by entry into a system that is simultaneously fully governed (stratum-spanning SOLID regulation, inheritance bounded to two roles), classification-permeable (patterns safely cross categorical boundaries), and pedagogically structured (starter patterns sample both behavioral subsystems) — the onboarding path exposes system reach while the governance that enables safe permeability also constrains the mechanisms available during partial mastery.
Onboarding introduces practitioners to a system whose permeability is safe precisely because the governance constraining novice misuse is the same governance enabling boundary crossing
