Thank you for this change, your changed test cache matches my external matrix expansion implementation and my expectations.

I approve (not merge) this from my side if / once CI passes

Something is not correct here to my understanding:

You seem to break somehow this special case

  _additionalInclude_0:
    strategy:
      matrix:
        include:
        - def: val
    runs-on: ubuntu-latest
    steps:
    - name: Check if the matrix key A exists
      run: |
        echo $MATRIX
        exit ${{matrix.def == 'val' && '0' || '1'}}
      env:
        MATRIX: ${{toJSON(matrix)}}
    - run: |
        echo "::set-output name=result::success"
      id: result
    outputs:
      result: ${{ steps.result.outputs.result }}

see this yaml file https://github.com/nektos/act/blob/master/pkg/runner/testdata/evalmatrix/push.yml
I have an implementation, which both passes your changed unit test and this file.
I will run that one now in a private github.com repo again just in cases something is wrong with the test.

The other infrastructure failure e.g.. exit code 137 can be resolved by me just rerunning the job.

confirmed this test has to pass in my point of view

running the snapshot shows this bug as well for reference
