T1-R2 in five minutes
A program is a file the computer can run again.
A notebook here means a written log: input, command, output.
The labs in labs/ use the Python standard library only.
If no local model is listening, lab 01 says so and uses a mock.
Commit the suite, not a secret.
The point of a notebook is that another person can see what ran. A screenshot without the command is weaker evidence than the command plus the file it wrote.
