You are a meticulous continuity editor for a fiction project. You have access to a "story bible" (codex) containing canonical details about characters, locations, items, lore, and organizations. Your task: Given the codex and a prose text, identify every factual inconsistency between the text and the codex. A violation is any detail in the text that contradicts what the codex states — wrong eye color, wrong location name, wrong ruler, swapped left/right, incorrect dates, etc. Be thorough. Check every named entity, physical description, location detail, date, title, and relationship mentioned in the text against the codex. Do not flag stylistic choices, omissions, or things not covered by the codex — only flag direct contradictions. For each violation found, output an XML element with the following attributes: - entry: the codex entry ID that is contradicted - detail: which specific detail is wrong — use the exact name of the codex element or attribute that is contradicted (e.g. "eyeColor", "species", "ruler", "material") - paragraph: the 1-indexed paragraph number containing the violation - substring: the exact substring from the text that contains the violation The element body should contain a brief explanation of the contradiction. Example format: <violation entry="1234" detail="hairColor" paragraph="2" substring="her brown hair flowing">The text says brown hair, but the codex says blonde.</violation> If you find no violations, output: <violations-none/> Output ONLY the violation XML elements. Do not include any other text, preamble, or explanation outside the XML.

"Prince Belphegor's domain of greed. Look—" She slid the book toward Lucien, who leaned over it with both his amber eyes narrowed in concentration. Lucien traced a line of text with a manicured finger. "The Ledger of Debts. My father mentioned it once — a record of every supernatural debt ever owed." He glanced at Eva. "That's the one," Eva confirmed, tapping the illustration. "And it originally came from Dymas, not Avaros." Upstairs, Detective Quinn sat in an unmarked car, her blue eyes watching the museum entrance. Her short blonde hair caught the streetlight as she raised a radio to her lips. "Suspect Kowalski entered the building twenty minutes ago. She's with a male companion — platinum blond, tailored suit. Keeping eyes on." </text> Identify all factual violations in the text above that contradict the codex.
