fix(ci): make gate freshness track completed results - #8312
Conversation
📝 WalkthroughWalkthroughGate freshness now evaluates the latest completed non-PR result on the default branch. Failed results count as fresh evidence. Reusable workflows require configured jobs to complete. Self-tests and documentation cover the updated behavior. ChangesGate freshness evaluation
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The freshness checker can incorrectly report gates as stale or incomplete when valid completed results exist because it does not examine all workflow runs and jobs. Pagination should be added before merge to avoid false alerts and incorrect gate status. Sequence Diagram(s)sequenceDiagram

- Around line 154-197: Update the workflow-run retrieval in the gate freshness
logic to paginate through every Actions API page before filtering candidates,
and likewise paginate the job lookup used when gate.job_names is configured so
required jobs beyond the first page are included. Preserve the existing event,
completion, conclusion, and timestamp selection rules, and add fixtures covering
an older late-completing run and a required job found after the first 100 jobs.

GitHub REST API list workflow runs pagination order creation time list jobs for workflow run per_page 100 pagination
💡 Result:
The GitHub REST API provides pagination support for both workflow runs and workflow jobs, allowing you to control the number of results per page using the per_page parameter [1][2][3]. Workflow Runs For endpoints listing workflow runs (e.g., GET /repos/{owner}/{repo}/actions/runs or GET /repos/{owner}/{repo}/actions/workflows/{workflow_id}/runs), the per_page parameter accepts a maximum value of 100 [1][3]. If you request more than 100, the API will cap the value at 100 [4]. These endpoints typically return results in reverse chronological order based on creation time, although this behavior can sometimes be influenced by filtering parameters [1][3]. Workflow Jobs For endpoints listing jobs for a workflow run (e.g., GET /repos/{owner}/{repo}/actions/runs/{run_id}/jobs), the per_page parameter also supports a maximum of 100 [2][5]. The default value for this parameter is 30 [2][6]. General Pagination Best Practices - Pagination Control: Use the per_page query parameter to set your desired number of results per page (up to 100) [1][4]. - Page Selection: Use the page parameter to specify the page number you wish to retrieve (default is 1) [1][2]. - Link Headers: To iterate through all results, rely on the Link header provided in the API response, which contains the URL for the next page of results [4]. - Capping: If you provide a per_page value greater than 100, the API will automatically reduce it to the maximum allowable value without returning an error [4]. Always check the Link header to verify if further pages are available [4].

Paginate both Actions API collections before selecting a result.
The workflow-runs endpoint returns runs by creation time. An older run can complete after every run on the first page, causing a false stale alert. The security-audit job lookup can also omit a required job after the first 100 jobs and treat a complete result as partial. Follow all pages for workflow runs and jobs. Add fixtures for both cases.

#8085 was combining three different states into one starvation alert.
gc-root-dominanceandnpm-publish-freshnesswere reaching runners and failing, while npm freshness already maintains #7491 for that live verdict.security-audit.ymlmoved behindworkflow_callin the CI-tier restructure, so its successful nested jobs were invisible to a checker that still queried standalone workflow runs.The revised live dry-run finds a recent completed result for all 12 configured gates. It does not publish, release, or bump any version. The bot-maintained issue can close itself after the merged checker confirms the gates are fresh.
