Objective: To create a detailed and reliable record of critical system actions for security analysis
and compliance.

Status:
No audit logs: The new workflow step copying cygwin1.dll and modified artifact upload introduce critical
build actions without any auditing or logging metadata beyond default GitHub Actions logs.

Objective: Ensure comprehensive error handling that provides meaningful context and graceful
degradation

Status:
Unchecked copy: The cp /bin/cygwin1.dll ./build_SITL/ step lacks existence checks and error handling for
missing DLLs or permission issues, which may cause silent or opaque failures in CI.

Instead of copying cygwin1.dll from a hardcoded path on the CI runner, check the
DLL file into the repository. This change will make builds more reproducible and
less dependent on the runner's environment.

Examples:

      - name: Copy cygwin1.dll
        run: cp /bin/cygwin1.dll ./build_SITL/

Solution Walkthrough:

Before:

# .github/workflows/ci.yml

- name: Build SITL
  run: ninja -j4
- name: Strip version number
  run: ...
- name: Copy cygwin1.dll
  run: cp /bin/cygwin1.dll ./build_SITL/
- name: Upload artifacts
  uses: actions/upload-artifact@v4
  with:
    path: | 
      ./build_SITL/*.exe
      ./build_SITL/cygwin1.dll

After:

# .github/workflows/ci.yml
# Assumes cygwin1.dll is checked into the repo, e.g., at tools/cygwin/cygwin1.dll

- name: Build SITL
  run: ninja -j4
- name: Strip version number
  run: ...
- name: Copy cygwin1.dll
  run: cp tools/cygwin/cygwin1.dll ./build_SITL/
- name: Upload artifacts
  uses: actions/upload-artifact@v4
  with:
    path: | 
      ./build_SITL/*.exe
      ./build_SITL/cygwin1.dll

Replace the hardcoded path to cygwin1.dll with a dynamic lookup using the which
command to make the CI workflow more robust.

.github/workflows/ci.yml [259-260]

 - name: Copy cygwin1.dll
-  run: cp /bin/cygwin1.dll ./build_SITL/
+  run: cp "$(which cygwin1.dll)" ./build_SITL/
