Pitfalls

• Distinguish allegations from adjudicated facts — use "alleged" or "purported" unless admitted or adjudicated.
• Prefer operative complaint and final orders; flag inconsistencies across versions.
• State "Not stated in record" for missing facts — never infer.
• Note whether the case is federal Rule 23 or a state analog; mark [VERIFY] if unclear.
• Omit sealed or protected information; note confidentiality limits.
• Highlight interlocutory appeals and their disposition.
