• De-emphasizes coherence with the original text; focuses on factual correctness only.
• Allows use of general world knowledge as valid ground truth.
• Only statements that are false, self-contradictory, or implausible count as hallucinations.
• Minor logical or coherence issues with the original text should not be considered hallucinations.
• Provides explicit label definitions for “No Hallucination”, “Possible Hallucination”, and “Definite Hallucination”.

V3 Differences from Base:

• Allows minor invented/unverifiable terms if plausible and not contradicting world knowledge.
• De-emphasizes off-topic or loosely connected content.
• Only clear factual errors or implausible claims are considered hallucinations.
• Plausible but invented terms or creative liberties are treated as “Possible Hallucination” unless they contradict the human continuation or known facts.

V4 Differences from Base:

• Removes ambiguity around coherence, style, and narrative oddities.
• Explicitly tolerates creative, loosely grounded content while still catching true factual errors.
• Instructs not to penalize for minor semantic or logical quirks in story continuations.
• Narrative oddities, off-topic content, or unusual story events are not hallucinations if plausible or creatively reasonable.

V5 Differences from Base:

• Most lenient: only clear, unambiguously false, self-contradictory, or impossible statements count as hallucinations.
• If uncertain, lean toward “No Hallucination”.
• Unusual, speculative, or imaginative content is not penalized.
• Plausible inventions or mild factual stretching are at most “Possible Hallucination”.
• Ignore coherence gaps, logical quirks, or off-topic continuations unless they make the text factually impossible.
