Safely Mixing Swift and C/C++

Source: documentation/cxx-interop/safe-interop/index.md
Proposed disposition: Needs determination — defer to C++ interop team (same group as Mixing Swift and C++)
Reviewer: @swiftlang/language-steering-group

Checklist

• Create a GitHub issue to track this migration once destination is confirmed
• Determine disposition alongside cxx-interop/index.md (same destination decision)
• Review source for accuracy against current Swift memory safety annotations for C++ interop
• Translate Jekyll markdown to DocC markdown format
  • Remove YAML front matter
  • Convert any Jekyll callouts to DocC-style callouts
  • Verify safety annotation examples compile under current toolchain
• Add article to target catalog's Documentation.md
• Run swift package generate-documentation --analyze --warnings-as-errors in the target package
• Preview locally with swift package --disable-sandbox preview-documentation
• Submit PR for appropriate team review
• After merge and publication: add redirect_to: in the swift.org source file's front matter
• Submit redirect PR to swift-org-website

Start with documentation/cxx-interop/safe-interop/index.md and compare its destination decision with cxx-interop/index.md, deferring the choice to the C++ interop team. Review the current memory-safety annotation examples, then translate the Jekyll markdown, update the target Documentation.md catalog, and run the listed documentation generation and preview commands. Done means the article is reviewed, published, and the source file receives its redirect_to: update.
