Who it applies to

It applies when all of these are true:

  • Service type — any answer

What engineering work it implies

Sample acceptance criteria Landfall generates for this obligation:

  • A 'Skip to main content' link is the first focusable element and becomes visible on focus
  • ARIA landmark roles (header/nav/main/aside/footer) mark the repeated regions
  • Heading structure lets users navigate past repeated blocks
  • The skip mechanism still works after SPA route changes
  • Unit tests cover the core logic (aim for >80% coverage on new code)

Not legal advice. Landfall maps regulatory obligations to engineering work for planning purposes. Its verdicts are not legal advice and create no attorney-client relationship — verify with qualified counsel before relying on them.

What Landfall Is NOT

Critical Boundaries

Understanding these boundaries is essential before using this product. Misuse of this tool for purposes outside its scope may create legal, regulatory, or commercial risk for your organization.

NOT Legal Advice

This product does not provide legal advice and does not create an attorney-client relationship.

Interpretations are informational analysis, not legal counsel. Always consult qualified legal professionals for compliance decisions.

NOT a Risk Score

We do not quantify, calculate, or certify your compliance risk level.

No numerical risk rating, compliance percentage, or safety score. Risk assessment requires human judgment about your specific context.

NOT Runtime Enforcement

This is a planning and mapping tool, not a runtime enforcement system.

Does not integrate with your production systems. Does not block, filter, or enforce compliance in real-time. Implementation is your responsibility.

NOT Regulatory Approval

Using this tool does not mean you are compliant with any regulation.

No certification, seal of approval, or compliance guarantee. Regulators will evaluate your actual implementation, not your use of this tool.

NOT Authoritative Interpretation

Our interpretations are not binding and may differ from regulatory guidance.

Only regulators and courts provide authoritative interpretation. Our analysis reflects our reading of requirements, which may be incomplete or incorrect.

NOT a Safe Harbor

This tool does not shield you from enforcement actions or liability.

Documentation of your process is valuable, but does not constitute a legal defense. Compliance is ultimately your organization's responsibility.

NOT an AI Compliance Agent

AI features assist analysis but do not make compliance decisions for you.

AI-generated interpretations require human review and approval. Automated suggestions are starting points, not final answers.

NOT Complete Coverage

We do not cover all regulations, all obligations, or all jurisdictions.

Regulatory landscape is vast and evolving. Gaps in our coverage do not mean those requirements don't apply to you.

What This Tool IS:

  • A structured workflow for mapping regulatory requirements to implementation tasks
  • A documentation system for compliance decisions (audit trail)
  • A collaboration platform for compliance, legal, and engineering teams
  • An informational resource for understanding regulatory obligations
