Harden CI cache safety review
Hard DevOps Basics arena: cache keys, lockfile integrity, dependency restore, and poisoned cache avoidance
Log in and clear the lower tiers to unlock this mission.
Missing prerequisites: devops-easy-ci-cache-safety
A CI job became faster, but test results now depend on stale cached dependencies. You are working inside a deployment operations lab, and the arena only clears when the result is safe, deterministic, and explainable.
Learn to apply cache keys, lockfile integrity, dependency restore, and poisoned cache avoidance in a deployment operations lab while explaining the invariant, safety constraints, and hidden edge cases.
- Demonstrates cache keys, lockfile integrity, dependency restore, and poisoned cache avoidance
- Handles the visible sample and hidden edge cases
- Keeps output deterministic and explainable
- Avoids unsafe dynamic execution
