GitHub Actions official documentation job outputs available when a needed job fails needs.result conditional expression

💡 Result:

Yes. A dependent job can read a needed job’s outputs and result—even if that job failed—provided the dependent job is allowed to run.

```yaml
jobs:
  build:
    runs-on: ubuntu-latest
    outputs:
      value: ${{ steps.set.outputs.value }}
    steps:
      - id: set
        run: echo "value=hello" >> "$GITHUB_OUTPUT"
      - run: exit 1

  report:
    needs: build
    if: ${{ always() }}
    runs-on: ubuntu-latest
    steps:
      - run: |
          echo "result=${{ needs.build.result }}"
          echo "value=${{ needs.build.outputs.value }}"
```

`needs.<job_id>.result` reports `success`, `failure`, `cancelled`, or `skipped`; outputs are accessed as `needs.<job_id>.outputs.<output_name>`. Without a condition such as `always()`, a job that needs a failed job is skipped by default. ([docs.github.com](https://docs.github.com/en/actions/how-tos/write-workflows/choose-what-workflows-do/pass-job-outputs?utm_source=openai))

**Caveat:** outputs set by steps that ran before the failure may be available. But if the job never reaches the step that sets an output, that output will be empty/unset. Define job outputs by mapping them from step outputs. ([docs.github.com](https://docs.github.com/en/actions/how-tos/write-workflows/choose-what-workflows-do/pass-job-outputs?utm_source=openai))

Require the watch marker before using an owned runner.

If marker creation or the watch upload fails, continue-on-error can leave runner failed or successful without an owned-pool-watch artifact. The rescue sweeper then cannot discover the queued owned job.

A failed job can still expose outputs produced before the failure. Therefore, making the upload mandatory alone does not guarantee Blacksmith fallback. Require needs.runner.result == 'success' before using the owned label.

Review comment at @.github/workflows/iroh-release-gate.yml at line 171:
Update the `runs-on` expression to use `needs.runner.outputs.label` only when
`needs.runner.result` is `success`, so failed runner jobs fall back to
Blacksmith even if they produced outputs. Also remove `continue-on-error` from
the marker creation and upload steps, and make the upload fail when the marker
file is missing.

This row says tailscale-version-skew can use an owned Mac. Line 770 of docs/ci-runners.md still says Iroh version skew stays on Blacksmith macOS 15. Remove or update the older row so the table gives one routing policy.

idle mini carries waits like any other queued owned job, so it is moved after
the same budget.

Dispatches of iroh-release-gate.yml are watched the same way. Its `runner`
job runs e2e_runner_pool.py for the Tailscale version-skew job alone, and
only takes an owned pool with a machine free now (no queue rounds), so that
job rarely waits. Its simulator-e2e jobs stay on Blacksmith, but they run in
the same run: a stuck owned job's rescue cancels them with it, and a refused
one's waits for them until the watch ends. The re-run of failed and
cancelled jobs keeps the modes that passed and puts everything on Blacksmith.
