Modules

engine

TM.1 (tutor-mode-ownership): the tutor’s gameplay engine — lesson open/seed, advance/retreat, score/lives gamification, the per-keystroke success check, and the HUD update — relocated here from dispatch.rs so the tutor module owns it. These stay impl Editor methods: a host-native builtin keeps its &mut Editor seam (BC.final).

mode

T.3 — TutorMode minor mode + headerline provider.

scores

T.B — Tutor high-score persistence.

session

T.1 — Interactive tutor data types.
