L4: Content Verification

L4 verifies AI-generated content for accuracy, compliance, and safety before it reaches end users. While L1 governs inputs and L2 governs reasoning, L4 is the final quality gate on outputs -- ensuring that what the AI produces meets your organization's standards.

Capabilities

Output Content Scanning

L4 scans all AI-generated outputs against configurable rule sets:

Content Scan Results:
  Output length:      842 tokens
  PII detected:       0 instances
  Sensitive content:  1 flag (financial projection without disclaimer)
  Compliance issues:  1 flag (missing required disclosure)
  
  Verdict: HELD -- requires disclaimer attachment before delivery

Scan categories include:

Category	What It Catches
PII leakage	Model reproducing PII from training data or context
Sensitive topics	Financial advice, medical guidance, legal opinions without proper disclaimers
Prohibited content	Content that violates organizational policy or regulatory requirements
Brand compliance	Off-brand messaging, unauthorized claims, competitor mentions
Data classification	Output containing data above the authorized classification level

Fact Verification Flags

L4 flags factual claims in AI outputs that require verification. Rather than silently passing through unverified claims, L4 marks them for review:

• Statistical claims -- percentages, dollar amounts, growth figures
• Regulatory references -- specific laws, regulations, or standards cited
• Date-sensitive claims -- information that may be outdated
• Attribution claims -- quotes or positions attributed to specific people or organizations

Fact Flags Are Not Blocks

Fact verification flags do not automatically block content. They annotate the output so reviewers know which claims need verification before publication or distribution.

Sensitive Content Detection

Identifies content that, while not necessarily wrong, requires additional review or handling:

• Medical information -- health-related content that could be interpreted as medical advice
• Legal guidance -- statements that could be interpreted as legal counsel
• Financial projections -- forward-looking statements or investment-adjacent content
• Personal recommendations -- AI providing personalized advice in regulated domains

Content Compliance Checking

Validates outputs against industry-specific compliance requirements:

Industry	Compliance Checks
Healthcare	HIPAA safe harbor, PHI redaction verification, clinical disclaimer requirements
Financial Services	Fair lending language, required disclosures, suitability disclaimers
Legal	Unauthorized practice of law detection, privilege warnings
Education	FERPA compliance, age-appropriate content verification
Government	Classification marking, CUI handling, FOIA considerations

Content Compliance Is Not Optional

In regulated industries, AI-generated content that reaches customers without proper compliance review exposes your organization to regulatory action. L4 provides the systematic gate that prevents this.

Operating Modes

Mode	Behavior
Monitor	All outputs are scanned and logged. Flags are recorded but content is delivered without delay.
Advisory	Flagged content produces a HELD verdict. Content is queued for review before delivery.
Enforce	Content that fails compliance checks is BLOCKED. Only clean content is delivered.

Integration

L4 evaluates content after the model produces its response. It receives the full output and any associated metadata (model used, prompt template, user context) to make its verification decision.

POST /govern
{
  "action": "content.verify",
  "payload": {
    "output": "Based on our analysis, revenue will grow 15% in Q3...",
    "model_id": "gpt-4o",
    "context": {
      "use_case": "financial_report",
      "audience": "external_stakeholders"
    }
  }
}
