Automate core reviewer requests and tiered PR approvals - #1040
Dynamically request the current active mini-software/core-reviewers team instead of using CODEOWNERS.
Add a tiered review policy: ordinary PRs require one eligible approval; PRs labeled major-change require three.
Publish the trusted Review approval policy commit status, excluding authors, bots, Read users, comments, dismissed approvals, and duplicate reviewers.
Refresh after PR/label changes and review submission/dismissal. A read-only review signal workflow triggers a trusted workflow_run handler so fork review events do not need write permissions or secrets.
Evaluate all open non-draft PRs, including all PRs sharing a commit, so an ordinary PR cannot overwrite a stricter PR's status.
Document team management, credentials, asynchronous updates, and safe activation.
Current setup and activation
The major-change label exists, and this governance/workflow PR carries it. The core-reviewers team has Write access; 18 nominated users are active and DD-6677/tonyqus have pending invitations.
The current native rule STILL requires three approvals for every PR. It was not lowered prematurely.
After merging this PR into master:
Run Review approval policy and verify its statuses on open PRs.
Atomically require the Review approval policy status from GitHub Actions and lower the main ruleset's native approval minimum to one, preserving existing bypass permissions.
Tiered approval checking uses GITHUB_TOKEN and requires NO additional secret. Dynamic team invitations separately require a fine-grained PAT stored as CORE_REVIEWERS_TOKEN, with mini-software as resource owner and organization Members: read permission. The local gh login token was not copied into Actions.
Validation
27 Node tests passed, including exact one/three approval thresholds, batching all 20 reviewers, deduplication, dismissal, label updates, manual reviewer refresh, API errors, and shared-commit enforcement.
actionlint v1.7.7 passed for all three approval/reviewer workflows.
git diff --check passed.
Team membership, Write permissions, main ruleset's unchanged three-approval requirement, and GitHub Actions integration ID were verified against GitHub.
Live approval Actions validation is pending merge; invitation automation also awaits its secret.
This is MiniExcel's chosen review policy, not a claim that ASF requires three reviewers on every GitHub PR.
Summary by CodeRabbit
New Features
Open, non-draft pull requests targeting master can receive automatic review requests from eligible core reviewers, excluding the author and reviewers who have already participated.
A review status now reflects approval requirements: one eligible approval for standard pull requests and three for those marked major-change.
Review status updates when relevant pull request reviews or changes occur.
Documentation
Added guidance on reviewer eligibility, approval requirements, workflow setup, and troubleshooting.
Two GitHub Actions workflows add automatic reviewer requests and approval-policy commit statuses for pull requests targeting master. Tests cover both workflows. CONTRIBUTING.md documents their setup and behavior.
Changes: Automatic reviewer requests
Layer / File(s)
Summary
Workflow activation and team loading .github/workflows/auto-reviewers.yml, .github/tests/auto-reviewers.test.cjs, CONTRIBUTING.md
The workflow handles pull-request and manual triggers and loads human members of core-reviewers. It fails if the token is missing or the team has no human members. Tests cover team loading and workflow configuration. The contributing guide documents setup and permissions.
Pull request eligibility and reviewer selection .github/workflows/auto-reviewers.yml, .github/tests/auto-reviewers.test.cjs
The workflow validates the PR number and skips closed, draft, or non-master pull requests. It excludes the author, previously requested reviewers, and reviewers who have submitted reviews. Tests cover these filters and manual PR-number validation.
Reviewer requests and confirmation .github/workflows/auto-reviewers.yml, .github/tests/auto-reviewers.test.cjs, CONTRIBUTING.md
The workflow requests eligible reviewers in batches of up to 15 and verifies each request. Tests cover API errors, confirmation, and repeated events. The guide documents refresh behavior and failures.
Review approval policy
Layer / File(s)
Summary
Workflow triggers and status initialization .github/workflows/review-approval-policy.yml, .github/workflows/review-changed.yml, .github/tests/review-approval-policy.test.cjs
The workflow refreshes on pull-request events, completion of PR review changed, or manual dispatch. It groups eligible open pull requests by head SHA and initializes pending statuses. The review-changed workflow runs on review submissions and dismissals. Tests check workflow configuration and permissions.
Approval requirements and review evaluation .github/workflows/review-approval-policy.yml, .github/tests/review-approval-policy.test.cjs
Ordinary pull requests require one eligible approval; major-change pull requests require three. Only each reviewer’s latest qualifying review counts, and eligible reviewers must not be bots or the PR author and must have write, maintain, or admin permission. Tests cover approval counts and review ordering.
Shared status results and policy documentation .github/workflows/review-approval-policy.yml, .github/tests/review-approval-policy.test.cjs, CONTRIBUTING.md
A shared SHA succeeds only when each associated pull request meets its approval requirement. Tests cover shared SHAs, label changes, API failures, and status-description length. The guide documents the policy and activation steps.

Merge Risk: Moderate · up to 0c8af
The new approval-status workflow can leave a PR stuck on a pending required check when a reviewer account is deleted or a permission lookup fails. Approved PRs can also lose a green status after a week of inactivity, and recovery needs a manual workflow run. Automatic reviewer requests also miss retargeted and Dependabot PRs. Address or knowingly accept these before the status is made required.

Handle PRs retargeted to master.
If a PR opens against another branch and its base changes to master, the change does not match any listed activity type. The workflow does not request reviewers until a later supported event or manual refresh. Add edited and retain the existing base-branch check. GitHub supports edited for pull_request_target and records base-reference changes separately. (github.com)
As per coding guidelines, “PRs targeting master automatically request active members” when updated.

Handle Dependabot-authored PRs before the token check fails them.
For a pull_request_target run of a Dependabot-authored PR, GitHub withholds Actions secrets and gives the run a read-only GITHUB_TOKEN. This applies when Dependabot opens a PR that targets master. In that case CORE_REVIEWERS_TOKEN is empty, so the check at lines 35-36 throws. The job fails before it requests any reviewers. Setting the repository Actions secret does not change this for these runs. (Dependabot restrictions)
The contributing guide requires automatic review requests for PRs targeting master. It does not exclude bot-authored PRs.
Choose one route for these PRs:
Skip Dependabot-authored PRs in the job if. Then request their reviewers manually or with the workflow_dispatch refresh, and document that step.
Request reviews with a credential that has pull-request write access on these runs. The read-only GITHUB_TOKEN cannot send review requests, so a Dependabot secret that only holds the team-read token is not enough.

Document the team visibility prerequisite for the token owner.
The roster request reads the members of core-reviewers. GitHub returns members only when the team is visible to the authenticated user. A secret team is visible only to its members and organization owners. If the token owner is neither, the roster request fails, and the workflow stops with an explicit error. The Members: read permission does not remove this requirement. Add this prerequisite to the setup steps.

Refresh successful statuses before they expire.
A required status must have succeeded within the past seven days. If an approved PR has no new events for seven days, this workflow does not refresh its status. The PR can become blocked until someone triggers another event or runs the workflow manually. Add a periodic refresh for open PRs. (docs.github.com)

Publish the policy status on each PR's merge commit too.
The workflow writes Review approval policy only to pull.head.sha (lines 37-39, 45-54, 99, 102). When a PR has a test merge commit with a status, GitHub evaluates required status checks against that merge commit. The pull_request workflows in dotnet.yml (line 4) and codeql-analysis.yml (line 17) can give that merge commit a status. Once this policy status is required, the merge commit can lack Review approval policy. The PR then stays blocked after its approvals are met.
Write the policy result to each PR's merge_commit_sha as well as its head SHA. Refresh that status when master changes, because the merge commit changes with the base branch. See GitHub: troubleshooting required status checks.

Skip reviews whose user is null.
GitHub’s review schema permits a null user, including after an account is deleted. For such a review, review.user.login throws. The run then leaves the initialized statuses pending and cannot finish evaluating the remaining PRs. Skip reviews without a user before reading login, and cover this case in the test harness.

Treat a 404 from the permission lookup as no repository access.
getCollaboratorPermissionLevel can return 404 for a reviewer who has no repository access. A public repository accepts approvals from such accounts. At .github/workflows/review-approval-policy.yml:80-84, the call has no error handling. The 404 therefore stops the script before lines 99 and 102 write a final status. The pending status from line 54 remains on the SHA, and later runs can hit the same error.
Treat a 404 as permission none. Rethrow all other errors so the existing failure behavior stays unchanged.
Add a test case that rejects the reviewer when the mock throws an error with status: 404. The current permission-failure test uses a generic error, so it does not cover this path.
