# Workspace Structure — retrieval verified

User retrieved five of six workspace components with correct lifecycles:
- MISSION: active compass
- learning-records: iterating dashboard (中控台监视屏)
- NOTES: persistent preferences
- lessons: disposable (次抛)
- reference: essence for frequent review

Missed RESOURCES.md but core understanding solid.

Self-generated insight: mixing different lifecycles wastes "认知带宽" (cognitive bandwidth) — a concept not in the lesson, indicating genuine integration.

On the fragments/roadmap boundary problem: user answered with pragmatic philosophy — "not every idea needs a solution, only focus on the most important one." This is an adult learning attitude: file systems serve the learner, not the other way around.
