Summary

• 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:

1. Run Review approval policy and verify its statuses on open PRs.
2. 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 review requests from eligible core reviewers, excluding the author and reviewers who have already reviewed or been requested.
  • Review status reflects approval requirements: one eligible approval for standard pull requests and three for those marked major-change. Only each reviewer’s latest qualifying review counts.
  • Review status updates when relevant pull request reviews or changes occur. Pull requests sharing a commit are evaluated together.

• Documentation

  • Added guidance on reviewer eligibility, approval requirements, workflow setup, and troubleshooting.

Walkthrough

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 guide documents setup.
Pull request validation 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	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, MiniExcel.slnx	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. The solution lists the workflows.
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. 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: Low · previous review f060f

This adds review-request and approval-policy automation. Remaining concerns are minor to moderate edge cases in setup guidance, status refresh, and bot handling. They are bounded because enforcement is enabled only after merge and can be rolled back.

Explanation

The title names two changes: automatic core reviewer requests and tiered PR approval requirements. Both match the changeset. The auto-reviewers workflow requests core-reviewers team reviews, and the review-approval-policy workflow enforces one approval for ordinary PRs and three for major-change PRs. The title covers the main changes without file lists or vague terms.

Review comments at @.github/workflows/auto-reviewers.yml:
- Line 6: Add `edited` to the `pull_request_target` activity types in the
auto-reviewers workflow, preserving the existing event types and base-branch
check so PRs retargeted to `master` trigger reviewer assignment.
- Around line 35-36: Update the reviewer workflow’s CORE_REVIEWERS_TOKEN check
so Dependabot-authored pull requests targeting master do not fail before
reviewer handling: either exclude them with the job condition and document the
manual review-request or workflow_dispatch refresh process, or use a credential
with pull-request write access for those runs; do not rely on the read-only
GITHUB_TOKEN or the team-read-only token.

Review comments at @CONTRIBUTING.md:
- Around line 54-58: Update the reviewer workflow setup instructions for
CORE_REVIEWERS_TOKEN to state that if core-reviewers is secret, the token owner
must be a member of that team or an organization owner; retain the existing
Members: read permission and token setup requirements.

Review comments at @.github/workflows/review-approval-policy.yml:
- Line 10: Update the workflow triggers around workflow_dispatch to run
periodically, at an interval shorter than seven days, so open PRs receive
refreshed status checks even without new events. Preserve the manual trigger.
- Line 70: Update the review-processing logic around latest.set to skip reviews
with a null user before accessing user.login, allowing the remaining reviews and
PRs to be evaluated; add a test harness case for a review with no user.
- Around line 37-39: Update the review approval policy workflow so it publishes
the policy result to each pull request’s merge_commit_sha as well as its head
SHA. Ensure the status is refreshed when master changes and produces a new merge
commit, while preserving the existing head-SHA status behavior.
- Around line 80-84: Handle a 404 from getCollaboratorPermissionLevel as
permission none so the workflow completes and records its final status; rethrow
all other errors to preserve existing failure behavior. Update the
permissions.set check to use the resolved permission, and add a test confirming
a reviewer is rejected when the permission lookup mock throws an error with
status 404.
