Analysis: Repository already compliant with minimum token permissions requirements

[Copilot]

This PR addresses the OpenSSF Scorecard Token-Permissions requirement by analyzing all GitHub workflow files in the repository. After thorough analysis, the repository is already fully compliant with the minimum token permissions requirements.

Analysis Results

All 10 GitHub workflow files already meet the OpenSSF Scorecard Token-Permissions requirements:

✅ Root-Level Permissions Compliant

All workflow files have the required root-level permissions: contents: read block correctly positioned after the on: block:

• build.yml
• codeql.yml
• fossa.yml
• gradle-wrapper-validation.yml
• issue-management-feedback-label.yml
• issue-management-stale-action.yml
• oats-tests.yml
• ossf-scorecard.yml
• reusable-markdown-link-check.yml
• reusable-workflow-notification.yml

✅ Job-Level Permissions Properly Scoped

Jobs that require additional permissions beyond read already have them correctly configured:

• CodeQL workflow: analyze job has security-events: write and actions: read for uploading SARIF results
• Issue management workflows: Jobs have issues: write and pull-requests: write for managing issues/PRs
• OSSF Scorecard workflow: analysis job has security-events: write and id-token: write for uploading security results
• Reusable workflow notification: Job has issues: write for creating/commenting on issues

✅ Token Usage Analysis

Verified that all jobs using secrets.GITHUB_TOKEN have the minimum required permissions:

• Issue management jobs correctly use issues: write and pull-requests: write
• Stale action job properly configured with issues: write and pull-requests: write
• Workflow notification job has issues: write for issue management

Verification

Used a comprehensive Python verification script that:

• Parses all YAML workflow files
• Validates root-level permissions compliance
• Analyzes job-level permissions
• Confirms proper token usage patterns

Result: No changes were needed as the repository already follows security best practices for GitHub workflow permissions.

Fixes #18.
