Summary

Multiple documentation files are missing the standard Copilot attribution footer. Additionally, exclusion paths are duplicated across package.json, workflow YAML, and script invocations—creating maintenance burden and local/CI divergence.

Files Requiring Footer

• docs/README.md
• docs/architecture/README.md
• docs/architecture/testing.md
• docs/architecture/ai-artifacts.md (replace alternate footer)
• docs/architecture/workflows.md (replace alternate footer)
• docs/contributing/ROADMAP.md
• docs/templates/security-plan-template.md
• GOVERNANCE.md
• .github/PULL_REQUEST_TEMPLATE.md (now excluded from validation)

Exclusion Path Consolidation

Problem: Exclusion paths are maintained in three places with inconsistent values:

• Validate-MarkdownFrontmatter.ps1 param defaults (empty arrays)
• .github/workflows/frontmatter-validation.yml (hardcoded + input default)
• package.json lint:frontmatter script

Solution: Consolidate all defaults into Validate-MarkdownFrontmatter.ps1:

[string[]]$ExcludePaths = @(
    'scripts/tests/Fixtures/**',
    'extension/README.md'
),

[string[]]$FooterExcludePaths = @(
    'CHANGELOG.md',
    'pr.md',
    'dependency-pinning-artifacts/**',
    '.github/PULL_REQUEST_TEMPLATE.md'
)

Then simplify callers to not pass explicit values.

Additional Fixes

• Fix docs/architecture/workflows.md ms.topic from 'architecture' to 'overview'

Acceptance Criteria

1. All listed files have the standard Copilot footer
2. Exclusion paths consolidated into script defaults
3. package.json and workflow simplified to rely on defaults
4. Local and CI validation produce identical results
5. npm run lint:frontmatter passes with --warnings-as-errors
