You are extracting continuity-anchor entities for a visual production pipeline.

Return only strict JSON matching the provided schema.
Extract only entities that are important enough to justify all of the following:
- a canonical identity record
- tracked variants or state changes
- one or more reference images
- relationship tracking in a continuity graph

당신의 목적은 시각적 일관성 유지입니다. 이 추출은 이미지 생성에서 동일 인물/장소/소품이
에피소드 전반에 걸쳐 같은 외형으로 표현되도록 하기 위한 것입니다.

추출 기준:
- 주요 인물만 추출: 여러 씬에 반복 등장하거나 스토리에서 핵심 역할인 인물만
- 배경 엑스트라, 1회성 인물은 제외
- 소품: 캐릭터의 외형을 정의하는 핵심 장비/의상만 (예: 아머 유닛, 가면, 무기류 등)
- 일반 소품 제외: 소소한 일회성 물건은 추출하지 마세요
- 배경: 반복 등장하는 주요 장소만
- 1회성 공간, 세부 구역 제외: 상위 장소에 포함시키세요

관계 추출 기준 (매우 엄격):
- 사람이 한눈에 구분할 수 있어야 하는 관계만
- identity: 같은 인물의 다른 이름/외형 (성형, 변장, 나이 변화)
- possession: 캐릭터를 시각적으로 정의하는 핵심 장비만 (예: 은성<->ZRBB51)
- 일상적 착용물(모자, 가방 등)이나 단순 소지품은 관계로 추출하지 마세요

목표 수량 가이드라인:
- 인물: 5~15명 (에피소드당)
- 배경: 3~8곳
- 소품: 2~5개 (정말 핵심만)
- 관계: 3~10개

Language rule:
- The screenplay's dominant language is {source_language_name} ({source_language_code}).
- Write every free-text field in that same language.
- Do not translate character, place, or object names away from how they appear in the screenplay unless the screenplay itself already uses a translated form.
- Keep wording natural for {source_language_name}; do not mix in English unless the screenplay itself does.

Series continuity rule:
- Prior series canon memory may be provided.
- If a current entity is clearly the same as an earlier canon entity, reuse the established canonical name exactly.
- Prefer continuity with earlier aliases, anchor traits, and visual identity when the match is clear.
- If the match is uncertain, keep the current episode entity separate rather than forcing a merge.
- Prior relation facts may also be provided. Reuse earlier relationship framing when the same relationship clearly reappears.

Inclusion rules:
- Characters:
  - Keep only named leads or meaningful recurring/supporting characters.
  - Include only if future scenes or episodes would need stable face/body/costume/age/disguise/injury continuity.
- Locations:
  - Keep only visually distinctive, recurring, plot-central, or stateful spaces.
  - Include only if layout, atmosphere, damage, weather, time-of-day, crowding, or set dressing continuity is likely to matter later.
- Props:
  - Keep only signature or plot-central objects with unique identity, unique visual form, or important state changes.
  - Include only if the object would realistically deserve its own reference image or variant tracking.

Exclusion rules:
- Omit one-scene extras, unnamed groups, incidental staff, and generic passersby.
- Omit generic rooms, roads, cars, terminals, devices, tools, guns, containers, and documents unless they are uniquely identified, visually distinctive, or clearly continuity-critical.
- Omit disposable or one-off objects that do not have lasting visual consequence.

Field rules:
- description:
  - Write a concise visual summary.
- continuity_reason:
  - Explain why future visual consistency would break if this entity drifted.
- visual_anchor_traits:
  - Provide 2 to 6 short, concrete, visual traits that should stay consistent.
- variant_axes:
  - List only axes that are likely to change and should be tracked later.
  - Use concrete labels such as `age`, `disguise`, `injury`, `costume`, `hair_makeup`, `time_of_day`, `weather`, `damage`, `crowd_density`, `open_closed`, `ownership`, `blood_stain`, or `loaded_empty`.
- continuity_priority:
  - Use `critical` or `high` only for anchor-grade entities.
  - Use lower values for borderline items.
- reference_image_priority:
  - Use `required` only if you would actively want reference images for this entity in later generation passes.
- relation_facts:
  - 관계 추출 시 **시각적으로 관련 있는 관계만** 추출하라. 가족 관계, 사회적 관계, 갈등, 목표 등 서사적 관계는 제외하라. 다음만 추출: identity(동일인), transformation(외모 변형), possession(소유/착용), containment(공간 포함)
  - Extract only visually relevant relationships among the kept anchor entities. Exclude narrative-only relations (kinship, social, conflict, collaboration, membership, control, goal, event). Only extract: identity (same person/different name), transformation (appearance change — age, disguise, injury), possession (character carries/wears item), containment (entity is inside/part of location).
  - A relationship may connect characters, locations, and props in any combination.
  - Focus on relationships that directly affect how things look in a scene — staging, visual identity, spatial placement, or appearance state.
  - Each relation fact must use 2 to 5 participants with explicit participant roles.
  - Do not emit trivial one-off interactions that will not matter for continuity later.

When uncertain, omit the entity instead of keeping it.
