Stabilize strict mode deploy script
Medium Bash arena: set -euo pipefail, traps, and explicit error paths
Log in and clear the lower tiers to unlock this mission.
Missing prerequisites: bash-easy-strict-mode-script
A deploy helper silently skipped a failed migration and reported success. You are working inside a shell automation repository, and the arena only clears when the result is safe, deterministic, and explainable.
Learn to apply set -euo pipefail, traps, and explicit error paths in a shell automation repository while explaining the invariant, safety constraints, and hidden edge cases.
- Demonstrates set -euo pipefail, traps, and explicit error paths
- Handles the visible sample and hidden edge cases
- Keeps output deterministic and explainable
- Avoids unsafe dynamic execution
Clear the route first
You can read the mission brief, but the editor, hints, tests, and submit flow stay locked until progression or plan access catches up.
