Verification
Every text unit in Gildea is independently verified against source evidence before being served through the API.
Trust contract
Only verdict=pass data is served. If a text unit fails verification, it’s excluded from API responses. You never see unverified or failed text units.
For arguments with mixed results: if 3 or more sibling sentences/claims pass, the review and fail siblings are auto-pruned. This ensures you see the strongest parts of each argument.
Thesis and summary text is always served complete — these are the article’s core narrative.
Scoring modes
Text units use two different verification methods:
| Mode | Used for | Method | Score range |
|---|
| nli | Claims | AlignScore NLI entailment | 0.0–1.0 |
| regression | Sentences | BGE-M3 regression scoring | 0.0–1.0 |
Scores are method-specific. A 0.74 NLI score and a 0.74 regression score mean different things. Use the verdict as the primary trust signal, not the raw score.
Verification detail levels
Default (compact)

"final_verdict": "pass",
"verification_path": "auto_pass",
"was_human_reviewed": false,
"scoring_mode": "nli",
"primary_score": 0.7421
}
}
