Lessons

• In zsh scripts, use a task-specific exit variable; status is read-only.
• Normalize accepted git diff --no-index exit 1 explicitly before chaining checks.
• Fail closed when no elements map; update empty-analysis report expectations.
• Remove obsolete imports after moving parsing into a shared helper.
• Deply relative paths resolve from analysis working directory; place extracted configs at target root for end-to-end validation.
• Quote Jekyll braces in rg patterns.
