CHAR-ANCHOR-001 提示词与执行规划

1. 执行顺序

确认角色文字简报（已完成，D-040）
  → 生成1张中性身份参考图
  → 检查身份、装备、构图和历史气质
  → 以同一身份图分别生成A/B/C三张风格方向
  → 本地拼成三联对比板
  → 用户选择一个风格
  → 重生一张高质量RGB母版
  → 本地生成六色模拟、RLCD和状态覆盖预览

身份参考图不是第四个风格候选，只负责锁定人物。三种方向必须把它作为同一张输入图，并明确标注为 identity reference。

2. 建议请求参数

参数只在正式执行前冻结；当前建议为：

三种方向使用三个独立请求，不使用一个请求的 n=3，因为它们不是同一提示词的随机变体。入选前不生成高质量版本，控制成本和评审负担。

3. 全部提示共享的角色事实

下列事实对身份图和A/B/C方向均不可变：

• 单人、完全原创的三国时代边塞都尉，男性，约35岁。
• 沉着、警觉、久经战阵；不是帝王、名将、仙人或夸张幻想英雄。
• 三分之四视角、腰部以上、竖向构图，面部位于画面上方约1/3。
• 头盔、单侧肩甲和环首刀形成三个清楚的大轮廓。
• 三个身份记忆点：缺口盔缨、铜质护符、左肩旧损甲片。
• 简化边塞城墙和旗影作为背景，不遮挡面部和装备。
• 不绑定任何既有游戏势力配色，不出现现有卡牌角色、官方卡框或Logo。
• 不生成姓名、势力字、技能文字、数字、水印和伪文字。
• 关键轮廓远离画布边缘，为3:4卡面、六色屏和300×400 RLCD保留裁切余量。

4. 身份参考图提示词

Use case: stylized-concept
Asset type: original historical character identity reference for a card-display product
Primary request: Create one clean, full-color character identity reference for CHAR-ANCHOR-001. This is a subject reference, not a finished trading card and not a style showcase.
Subject: A completely original frontier military captain from the Three Kingdoms era, male, around 35 years old, calm, alert, weathered by long service, clearly human and historically grounded. He is not an emperor, famous general, immortal, or fantasy hero.
Core equipment: a helmet, one asymmetrical shoulder guard, and a ring-pommel saber. Identity memory marks: a visibly notched helmet plume, a small bronze protective charm, and one old damaged plate on the left shoulder. Keep the three memory marks simple and unambiguous.
Composition/framing: portrait near 3:4, waist-up three-quarter view, face in the upper third, clear silhouette for helmet, single shoulder guard, and saber; generous crop-safe margin on every side.
Scene/backdrop: a restrained frontier wall and distant flag shadows, simple enough not to compete with the subject.
Style/medium: neutral professional character concept illustration, balanced realism, controlled detail, clean readable shapes, full-color RGB.
Lighting/mood: calm overcast daylight with clear facial planes and no crushed shadows.
Text: none.
Constraints: one character only; plausible Han-era military influence; preserve readable face, age, equipment, and silhouette; no card frame; no UI.
Avoid: any existing game character, 三国杀 visual assets, logos, watermarks, faction glyphs, pseudo-Chinese text, extravagant emperor costume, xianxia armor, oversized fantasy weapons, extra limbs or fingers, cropped helmet or weapon, noisy background, extreme cinematic darkness.

身份参考图通过条件：年龄、表情和装备符合简报；三个记忆点都能辨识；缩小到300×400时大轮廓仍成立。若失败，先修身份图，不带着错误进入三种风格比较。

5. A/B/C共同编辑约束

A/B/C均以 CHAR-ID-REF-001 作为输入图，采用下列公共编辑要求：

Input image: Image 1 = identity reference and composition reference.
Change only the rendering language described in the Style delta below.
Preserve the same person, apparent age, face structure, expression, gaze, helmet and notched plume, bronze charm, left damaged shoulder plate, ring-pommel saber, pose, camera angle, crop, background layout, and clear silhouette.
Do not add or remove equipment, characters, text, logos, symbols, or UI.
Keep full-color RGB; do not imitate an e-ink preview and do not apply six-color dithering in the generated master.

6. A方向：历史写实厚涂

Use case: historical-scene
Asset type: visual style direction A for an original character card master
Primary request: Render the provided identity reference as a historically grounded, cinematic painted character portrait.
Style delta: realistic facial anatomy, natural skin and fabric, convincing worn metal and leather, restrained painterly brushwork, subtle atmosphere, dimensional but readable lighting. Preserve clear midtone separation so the image does not depend on near-black shadows.
Constraints: retain all shared identity and composition invariants; premium full-color editorial illustration; no photorealistic camera artifacts.
Avoid: excessive gradients, muddy shadows, hyper-detailed background, glossy fantasy armor, epic magical effects, text, border, logo, watermark.

7. B方向：新国风重彩版画

Use case: stylized-concept
Asset type: visual style direction B for an original character card master
Primary request: Render the provided identity reference in a modern Chinese heavy-color printmaking language optimized for strong silhouette and limited-palette conversion.
Style delta: decisive outer contours, controlled hard-edged color regions, print-like shadow shapes, restrained carved-line texture, selective bronze and cloth details, layered depth without relying on smooth gradients. Premium collectible-card presence, not a flat poster.
Constraints: retain all shared identity and composition invariants; face and equipment must remain dimensional and readable; full-color RGB master prepared for later offline six-color and 1-bit conversion.
Avoid: crude comic outlines, flat clip-art appearance, dense decorative noise, tiny repetitive patterns, ink-wash fog covering the subject, text, border, logo, watermark.

8. C方向：极简工笔海报

Use case: stylized-concept
Asset type: visual style direction C for an original character card master
Primary request: Render the provided identity reference as a restrained contemporary gongbi-inspired editorial poster with generous visual breathing room.
Style delta: precise controlled linework, simplified planar colors, limited shading, elegant negative space, calm decorative rhythm, clear separation between subject and background. Preserve enough material contrast to distinguish face, helmet, shoulder armor, charm, and saber.
Constraints: retain all shared identity and composition invariants; sophisticated and collectible rather than instructional or childish; full-color RGB.
Avoid: pale low-contrast face, fragile hairline details that vanish at small size, empty unfinished appearance, decorative border, text, seals, calligraphy, logo, watermark.

9. 本地比较板

三张方向图生成后，不让Image 2重新画拼版。电脑端统一制作 CHAR-DIR-SHEET-001：

• 三列等宽，使用同一裁切比例和显示面积。
• 只在图片外部添加A、B、C编号和风格名称。
• 同时放置RGB缩略图、临时六色缩略图和RLCD缩略图，避免只在全彩大图上做决定。
• 不对某一候选单独增强对比度、锐度或饱和度。
• 记录三张原图路径及对比板裁切坐标。

10. 入选母版重生提示框架

选定风格后，不直接把1536×2048候选当最终母版。以身份参考图和入选方向图共同作为输入：

Image 1 = identity reference; preserve the person and all identity details.
Image 2 = selected style reference; preserve its rendering language, palette logic, material treatment, and detail density.
Create a new high-resolution RGB master at the requested portrait size.
Keep the approved composition and generous crop-safe margin.
No text, card frame, UI, faction logo, watermark, or six-color dithering.

最终提示还要重复身份不变量与所选风格的避免项，不能只写“做成高清版”。

11. 开始生成前的检查清单

• 用户已经明确授权开始出图，而不只是确认角色设定。
• gpt-image-2生产路径、账户可用性和当前规格已复核。
• 输出目录、文件名和manifest位置已建立。
• 三个风格提示除 Style delta 外没有无意差异。
• 生成结果将保存进项目，不只保留在默认生成目录。
• 已准备身份图审核节点和三方向选择节点，不会连续自动生成完整批次。
