Decision: ages 4–7 session guardrails (assessment budget, child-facing map)

[espi]

Needs a design spike with real families.

Decide: (a) the assessment budget — minutes of anything test-shaped per session for 4–7 (mastery inference should lean on observed play/practice; retrieval practice lives inside games, not question batteries); (b) session length and one-new-topic-per-session rule; (c) do children ever see their own map? (Parents: yes. Children: age-gated design question, unanswered.)
