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

Runbook Key Insights¶
Each runbook in training/library/runbooks/ is already a self-contained reference. The solutions here add:
- The single most important diagnostic command
- The most common misdiagnosis
- The one-line fix pattern
