[bug\_fix] Reusable workflow fails with 'Input required and not supplied' or secret appears empty/null despite being defined in caller workflow

Reusable workflows do not automatically inherit secrets from the caller. The root cause is that secrets must be explicitly passed using the secrets keyword in the caller's job definition \(secrets: inherit to pass all, or secrets: specific\_secret: $\{\{ secrets.SECRET\_NAME \}\} for specific ones\). Additionally, the reusable workflow must declare the secret in the on.workflow\_call.secrets mapping with required: true or false to receive it.

Journey Context:
You refactor a deployment workflow into a reusable workflow in .github/workflows/deploy.yml. It requires an AWS\_ACCESS\_KEY\_ID. In the caller workflow, you define job: call-deploy: uses: ./.github/workflows/deploy.yml and set env: AWS\_ACCESS\_KEY\_ID: $\{\{ secrets.AWS\_ACCESS\_KEY\_ID \}\}. The job fails with 'Unable to locate credentials'. You check the reusable workflow and see it uses secrets.AWS\_ACCESS\_KEY\_ID, but it's empty. You search GitHub documentation and find that reusable workflows are isolated and don't inherit secrets automatically. You update the reusable workflow to declare secrets: AWS\_ACCESS\_KEY\_ID: required: true in the on.workflow\_call section, and update the caller to explicitly pass secrets: AWS\_ACCESS\_KEY\_ID: $\{\{ secrets.AWS\_ACCESS\_KEY\_ID \}\}. The workflow then authenticates successfully.
