ballerinaWhy Your Deploy Script Lied to You: Bash Strict Mode as an Engineering Decision
Bash's 'strict mode' (set -euo pipefail) turns silent failures into loud ones — especially pipefail, which stops 'build.sh | tee log' from masking a broken build. Here's what each option does, a worked deploy script, and the honest trade-offs.
