Solutions

Hint ladders and answer keys for labs and runbooks. Designed to help when you're stuck without instantly spoiling the learning.

How to use

1. Try to solve the lab on your own first
2. If stuck, start with Hint 1 (most general)
3. Work through hints progressively -- each reveals more
4. Only read the Minimal Solution if you're completely stuck
5. Always read the Explain section after solving (even if you solved it yourself)
