What you'll learn

• Your message is the tiny last line of a giant package, and every turn the whole thing goes out again.
• The cache keeps the maths, not your words, and it only works on the start.
• Switching models? Miss! Changing effort? Miss! And everything has a timer, unless you keep it warm.
• Tools first, then system, then messages. Touch the top, rebuild the lot. Skill unlocked: Cache Freeze!
