Unsure about restoring cache

[h2oearth]

I have a testing-cache job used by a parent job, which can run multiple times. The first time will generate a prefix, which the following jobs will use.

I want to be able to restore the cache and use the data to restore the prefix.

I want to stay away from using artifacts.

Thank you :-)

jobs:
  testing-cache:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout Repository
        uses: actions/checkout@v4
      - name: Cache
        uses: actions/cache@v3
        with:
          path: '~/postfix-run-number.txt'
          key: ${{ runner.os }}-${{ github.run_number }}
      - name: Generate Postfix Job Number
        id: generate-postfix-run-number
        run: |
          if [[ ${{ inputs.event }} =~ ^Start ]]; then
            postfix=$RANDOM
            echo "$postfix" > ~/postfix-run-number.txt
            echo "postfix=$postfix" > "$GITHUB_OUTPUT"
          else
            postfix=$(cat ~/postfix-run-number.txt)
            echo "postfix=$postfix" > "$GITHUB_OUTPUT"
          fi
          echo "$postfix"
