10-minute daily review

Two architecture, two training and inference, two RAG and agents, two security, one connection question and one teach-back. Concepts you missed or guessed come first.

A lightweight deterministic review schedule: each correct answer moves a concept to a longer interval (now, 1, 3, 7, 21 days); a wrong answer moves it back to now. It is simple on purpose, not a scientifically optimized algorithm. Everything is stored only in this browser. Also see I keep confusing these.
