Report #8136

[bug\_fix] Job outputs empty or undefined when referenced by downstream jobs

Explicitly map step outputs to job outputs by adding an \`outputs:\` section to the job definition that references the step's output using the expression \`value: $\{\{ steps.step\_id.outputs.output\_name \}\}\`. The step must write to the \`$GITHUB\_OUTPUT\` file \(or use the deprecated \`::set-output\` command\).

Journey Context:
A developer has a "build" job that calculates a version number and a "deploy" job that needs it. The build step runs \`echo "version=1.2.3" >> $GITHUB\_OUTPUT\`. In the deploy job, they reference \`needs.build.outputs.version\` but it resolves to an empty string. The developer checks the build job logs and confirms the step output is set correctly. They search documentation and realize that while steps have outputs, jobs do not automatically expose them. The missing link is the \`outputs:\` definition at the job level in the workflow YAML. They must add \`outputs: version: $\{\{ steps.step\_id.outputs.version \}\}\` to the build job definition to bridge the step output to the job output, making it available to downstream jobs via the \`needs\` context.

environment: Multi-job workflows with dependencies \(needs\), passing metadata like versions, URLs, or build artifacts IDs between jobs. · tags: outputs needs job-outputs mapping steps context · source: swarm · provenance: https://docs.github.com/en/actions/using-jobs/defining-outputs-for-jobs
