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.

The bar's red neon sign buzzed faintly outside. Silas was behind the counter, polishing a glass with his usual calm demeanor, his silver signet ring glinting on his left hand. "You're late," Silas said, running a hand through his dark brown beard. He set the glass down and limped around to her side, favoring his right leg as always. Aurora pulled the Heartstone Pendant from her jacket — the golden chain catching the low light — and placed it on the bar top. "I found something in Dymas. Prince Mammon's realm is unsettling. The feasts never end." "The Wardens won't be happy," Silas muttered, glancing at the iron pin on his lapel — a closed eye, the mark of their order. "You know they've been watching us since their founding in 1066." Rory shuddered. Her Half-Fae senses told her something was wrong. The Veil felt thin tonight — the summer solstice always weakened it. </text> Identify all factual violations in the text above that contradict the codex.
