Scope

Use when:

• outputs must avoid introducing unsupported facts,
• the text contains dense technical claims,
• terminology drift causes ambiguity or policy violations.

Rules (normative)

1) Evidence boundary must be explicit.

• If not provided, fail-closed and request it.

2) Classify every non-trivial claim:

• FACT (SUPPORTED)
• INFERENCE
• NOT VERIFIED

3) Maintain a Claim Ledger:

• ID

  Claim

  Label

  Evidence/Rationale

  Fix

4) Terminology consistency:

• define key terms once (short glossary),
• do not shift meanings mid-text.

5) Overclaim handling:

• flag any claim that exceeds the evidence,
• replace with narrower, evidence-aligned language.

6) Output requirements:

• Clean final text (revised),
• Confidence score (0–100) based on evidential support + internal consistency (not probability).

Non-compliance examples

Non-compliant outputs include:

• new factual claims without support,
• missing claim classification for material claims,
• missing Claim Ledger,
• contradictions between claim labels and the evidence boundary.
