Start a new topic

yat:new-env makes an env: a folder under envs/ that holds everything about one topic. Behaviour comes from the other skills, so a new topic never needs new code.

What you say

You say	What happens
I want to learn <topic>	The interview, then the env
new env / add a learning environment	The same

The interview

One question at a time:

1. What do you want to learn, and what will you be able to do when you're done?
2. What do you already know that the tutor can use for analogies?
3. How do you like to be taught? Skip anything you have no opinion on.
4. Which days can you show up?
5. Should it teach by questions (socratic), by making a real thing together (project), or sit beside you while you create (passenger)?

It then copies the closest template from examples/envs/ (practice-drills, project, creative-draft, language-practice, math-science or _template), fills it in from your answers, and tells you the one phrase to start: let's do <env>.

It never fills the roadmap with content you haven't chosen, and it never starts teaching while it scaffolds.

What it makes

File	Holds
env.toml	Tier, cadence, mode, terminal rule, register
CLAUDE.md	What the material is, what you already know, what "done" means
tutor.md	How you want to be taught, in your own words
roadmap.md	Five to ten units, each with a "done when" sentence
session-state.md	The first bookmark, with a specific first move

Terminal: allowed, because scaffolding is setup, not a learning session.
