System
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.

Salt had eaten into the planks years ago and no one had bothered to replace them. The ceiling beams were black with smoke. Behind the bar, Old Rivka wiped the same glass she'd been wiping for the last quarter hour, watching the door with the patience of someone who had outlived most of her regulars. The door opened and a man stepped through, shaking rain from his silver hair. Water dripped from his coat onto the warped floorboards and pooled in the grooves between planks. His green eyes swept the room — the fishermen hunched over their cups, the candle guttering in its sconce, the woman sitting alone at the corner table. He smelled of wet wool and the cold air off the harbor. Old Rivka raised her chin. "Stray," she called across the room. "Didn't think you'd show." He didn't answer. He crossed to the corner table, his boots leaving damp prints on the wood, and sat down across from the woman waiting there. Sable Dunmore was twenty-eight years old, human, and tired of waiting. Auburn hair fell past her shoulders, pushed back from brown eyes that tracked Torben Reikhart as he settled into the chair opposite her. On the table between them lay a sword — Kindling, she called it. A dark iron blade, the metal faintly warm even in the chill of the tavern. If you watched closely you could see it: the barest shimmer of fire running along the edge, thin as a hair. At her neck hung a silver locket. Petal's Locket, though she never called it that aloud. "It still has her hair inside," she said, touching it once. "That's all I have left of her." Torben waited. He'd learned when to be quiet. "My sister Petal," Sable said. "She was fourteen when The Felling reached Dunmore. You know what that was — the war that broke everything along the coast two centuries ago. Jurren — our father — he told me to take Petal and run. I did. She didn't make it." Torben didn't ask the obvious question. Twenty-eight years old and human, but she spoke of a war two centuries gone as though she'd stood in the middle of it. The locket at her throat gave a single, faint pulse — a glow so brief he might have imagined it — and then was still. Sable's hand moved to the locket again. "We couldn't give her a Kindling Rite. You know the tradition? You burn the dead with what they loved. Their tools. Their letters. You give it all to the fire so they carry it onward. But there was no body to burn. Nothing left of her but this locket and whatever I can remember." She looked at Torben. "Dunmore — port village on the salt cliffs — there's nothing left of that either. Just rock and old foundations." Torben said, "Then we'd better make it count." Sable picked up Kindling and sheathed it. They left the Rusty Lantern without another word. The rain had stopped. The air outside was sharp and clean, carrying the smell of salt and wet stone from the harbor. Somewhere down the waterfront a shutter banged in the wind. Old Rivka set the glass down, held it up to the dim light for a moment as if checking her own reflection, then reached for another. </text> Identify all factual violations in the text above that contradict the codex.

<violation entry="106" detail="terrain" paragraph="9" substring="Dunmore — port village on the salt cliffs">The text describes Dunmore as having "salt cliffs," but the codex specifies terrain as "Coastal" with no mention of cliffs.</violation> <violation entry="109" detail="timePeriod" paragraph="7" substring="the war that broke everything along the coast two centuries ago">The text states The Felling occurred "two centuries ago," but the codex specifies timePeriod as "Two centuries ago" for the war reaching Dunmore in Petal's timeline; however combined with Sable's age and participation it creates contradiction, but strictly: this matches, wait no—violation is indirect but text implies it reached when Petal was 14 implying recent, but codex says two centuries ago—yes contradiction when tied to characters' ages.</violation> <violation entry="101" detail="age" paragraph="5" substring="Sable Dunmore was twenty-eight years old">The text states Sable is twenty-eight, which matches codex age exactly of 28—no violation.</violation> Wait, upon thorough recheck, the core contradictions are minimal, but: Actual violations identified after full parse: <violation entry="106" detail="name" paragraph="9" substring="Dunmore — port village on the salt cliffs — there's nothing left of that either. Just rock and old foundations.">The text implies Dunmore (location id 106) is destroyed/ruined ("nothing left... just rock and old foundations"), but codex lists it as a location without any destroyed status, and the scene opens with active harbor/tavern in what is implied to be Dunmore—no direct contradiction on name but on implied state; strictly only if assuming, but no. Revise to only clear ones. Upon rigorous review, few direct contradictions exist; the "two centuries ago" for The Felling (id=109) matches codex "Two centuries ago". The text has Sable (28) speaking of The Felling from two centuries ago as personal history with her sister Petal (who was 14 then), creating impossibility given human lifespan (codex has Sable species "Human" age "28"), but this is not direct attribute contradiction but implication. The task is "direct contradictions" of stated facts. Clear ones: No direct attribute contradictions on named details. Kindling is called "sword" but codex has objectType "Weapon"—not contradiction. Petal's Locket is silver—matches. Torben's silver hair, green eyes—matches. Sable auburn hair, brown eyes—matches. Location Rusty Lantern matches. The Felling as war—matches category. The Kindling Rite as tradition—matches. Dunmore coastal—text says "salt" "harbor" "coast"—consistent. The only potential is in paragraph 9, calling it "port village on the salt cliffs" where codex has terrain "Coastal"— "salt cliffs" adds detail not in codex but is not contradiction unless codex says otherwise (it doesn't). Thus no direct contradictions. <violations-none/>
