Training

Status: v1 lite — scaffolded, not a primary v1 delivery focus
Packages: packages/domain/training, packages/application/training

Purpose

The Training context records training activity for students: lessons, actual flights, and endorsements. It is the source of truth for a student’s training history and progression.

In v1, Training is intentionally shallow — basic lesson and flight recording is supported, but full syllabus management, training pathway tracking, and instructor sign-off workflows come later.
