上一轮收束摘要只说明运行结果、失败原因和已提交任务;它不要求重做历史任务。已提交收费任务不得因续聊或恢复提示自动重发。 +## 布局与整理 + +节点位置属于用户手工编辑的空间,只在两种情况下整理:用户明确要求整理、归类或排版;或你新增的节点会与现有节点重叠(服务端在未给坐标时会自动落位,通常不需要你处理)。 + +- 整理用 `canvas_arrange_nodes`:先读取画布拿 `snapshotHash`,只改坐标,不改内容、不建连线、不改层级,也不把节点收进背板。 +- 归类用 `groups`:你决定"哪些节点属于同一场景/同一镜头组"和组的顺序,位置由服务端算;分组只形成横向位置带。 +- 新增节点时不要自己算坐标:省略 `x`/`y` 让服务端按画布内容落位(靠近依赖的输入在左、输出在右,或追加到同类节点之后)。只有用户明确要求某个位置,或需要微调单个节点时,才用 `update_node` 的 `x`/`y`。 +- 锁定节点、背板等容器节点、隐藏批次子节点和已归属背板的子节点不会被动;整理要跳过它们,不要为了统一外观去动用户的锁定布局。 +- 整理会改变画布快照:整理后要重新读取画布再继续写入,不要复用旧的 `snapshotHash`。 + ## 能力使用 以工具返回的能力清单为准,不猜测节点类型、字段、连接关系或模型选择。节点选择由你结合用户目标、镜头数量、连续性和后续维护需求判断:单个画面、一次性提示词或快速试验通常使用文本/Markdown与媒体节点更轻量;多镜头、逐镜审查、逐镜生成、资产关联或需要交接维护时,分镜脚本通常更合适。不要为了形式创建复杂节点,也不要用普通文本伪装成结构化分镜;如果选择轻量节点处理多镜头草稿,不要声称它具备镜头级维护能力。结构化数据节点应通过其专用字段和分页读取,不把整份数据塞进上下文。`sourceNodeId` 只用于能力清单声明为文本输入来源的节点;媒体资产只通过 `referenceNodeIds` 建立真实引用,文字中的编号不能替代引用。模型选择必须复制模型目录返回的完整 `selection`,不要把任意 ID 猜成 `logicalModelId`。 diff --git a/backend/internal/prompts/agent_policy_test.go

与库计时器(会失步);variant 对象驱动一切可变项。\n\n## I — 方法论骨架 (Interpretation):\n\n1. **时间码先于剪辑**:drop 与瞬态是测量出来的,不是听出来的。\n2. **重切配重拍**:kick/snare 位放大切点力度,轻拍位放过渡。\n3. **ramp-then-hardcut**:进 drop 加速、出 drop 硬切——张弛结构。\n4. **一拍一信息**:0.6-1.0s 一拍,每拍只讲一个卖点(关键词+单一支撑画面)。\n5. **确定性渲染**:帧函数式动画=逐帧确定,禁时间器类失步源。\n\n## A1 — 应用案例 (Past Application)\n\n- 来源实践:beats 数组逐拍调度 feature 卡(pop 0.35s cubic-bezier(.22,1,.36,1))——速度感来自统一曲线而非快切本身。\n- 反例:按 1s 整数网格切——画面节奏与音乐长期微漂移,观感「两张皮」。\n\n## A2 — 触发场景 (Future Trigger)\n\n- 任何要卡点的广告/短片/MV。\n- 「画面音乐不合拍」的修复(先查瞬态切点)。\n- 影策 Agent 生成卡点结构的分镜参数。\n\n## E — 可执行步骤 (Execution)\n\n1. **测时间码**:记录 drop 与主要瞬态位置。\n *完成标准*:时间码表成文。\n2. **排砸点**:品牌标 snap 于 drop 帧+微过冲+白闪。\n *完成标准*:砸点=drop 帧。\n3. **配瞬态切**:重切落 kick/snare,过渡落轻拍。\n *完成标准*:切点-拍点对应表成立。\n4. **ramp 进出**:进 drop ramp,出 drop 硬切。\n *完成标准*:ramp 与硬切在位。\n5. **蒙太奇拍驱**:0.6-1.0s 一拍一卖点+统一运动曲线。\n *完成标准*:拍-卖点对应且曲线统一。\n\n---\n\n许可与署名:本技能方法论蒸馏自开源项目

高级感发布片弧线——①**Hook(0-3s)**:一个停滑的帧或运动;②**Tease(3-9s)**:暗示产品,建立好奇,卡点建立;③**Reveal(9-13s)**:产品/logo 砸在音乐 drop 上;④**Feature montage(13-25s)**:快节奏运动感,一镜一卖点;⑤**End card(25-30s)**:logo+slogan+CTA 干净定格。**30s 比例分配表**即上表;15s 收紧、60s 加长蒙太奇(**绝不加长 hook**)。两条铁律:①**声音设计引领画面**——先锁音轨、标出 beats 与 drop,再让画面切在标记上;永远不要给剪好的片子配乐(reveal 要落在 drop 上不是附近)。②**质量胜过数量**——几个完美镜头胜一堆平庸镜头,不高级的镜头全砍。\n\n## I — 方法论骨架 (Interpretation):\n\n1. **比例即结构**:五拍占比是骨架——15s/60s 只缩放中段,hook 恒定 3s。\n2. **先锁轨后剪画面**:声音是时间轴的主人,画面是客人。\n3. **Reveal 是唯一高潮**:全片为品牌砸点服务,蒙太奇不许抢戏。\n4. **End card 要静**:定格 ≥2 秒,让品牌落地——CTA 区禁忙动。\n5. **高级感=减法**:砍镜头是发布片的主要创作手段。\n\n## A1 — 应用案例 (Past Application)\n\n- 来源实践:新品发布片先锁 30s 音轨标 drop@9.0s→reveal 精确落点+微过冲(scale 1.18→1.0,0.18s 回弹)→品牌记忆点成立。\n- 反例:先剪画面后配乐——reveal 落在 drop 附近而非点上,冲击力减半。\n\n## A2 — 触发场景 (Future Trigger)\n\n- 新品上市/功能发布/sizzle 片。\n- 「品牌时刻没砸中」的重剪(先查锁轨顺序)。\n- 影策 Agent 生成发布片结构的默认骨架。\n\n## E — 可执行步骤 (Execution)\n\n1. **定总长**:15/30/60s,按比例表铺五拍。\n *完成标准*:五拍占比合规(hook 恒 3s)。\n2. **锁音轨**:先选轨标 beats/drop。\n *完成标准*:drop 时间码已记录。\n3. **排 reveal**:品牌砸点对 drop+微过冲。\n *完成标准*:砸点=drop 帧。\n4. **铺蒙太奇**:一镜一卖点,运动语言统一。\n *完成标准*:卖点-镜头一一对应。\n5. **静尾板**:end card 定格 ≥2s 无竞争动效。\n

角色A定妆照(reference_image)`、` = 客厅场景图(reference_image)`。一镜内别名唯一。\n3. **别名 → 保留关系**:在保留关系段写\"保留 的脸型/发型/服装\"——文字侧保险,与参考图双保险。漫剧/真人风格差异只写在画风规范字段(如\"2D 国漫平涂风格\"),不改人物描述。\n\n**一致性失效排查序**:先查参考图质量(是否正脸/清晰)→ 再查保留关系段是否抄全视觉锚点 → 最后查是否违规混用首尾帧。\n\n## A1 — 书中的应用 (Past Application)\n\n- **双角色同框**:``=角色A、``=角色B,保留关系段分别声明两人锚点;生成时两人身份不互串。\n- **漫剧改真人**:同一份角色卡,画风规范字段从\"2D 国漫平涂\"改为\"真人实拍质感\",人物描述不动——ip-style-decoupling 的画风解耦在 H3 侧的落地。\n\n## A2 — 触发场景 (Future Trigger)\n\n- 阶 ⑧→⑨ 交接:资产卡确认后,逐张绑定为素材别名,产出绑定清单(assets.json 增补 alias 字段)。\n- 阶 ⑩ 衔接轴:检查角色资产跨镜一致(别名是否全程指向同一参考图)。\n- 语言信号:\"换镜头变脸 / 角色不一致 / 画风漂移\"。\n\n## E — 可执行步骤 (Execution)\n\n1. **核对参考图**:每个角色/场景/道具是否有合格参考图?角色图必须正脸清晰;缺图→先补图再绑定。\n *完成标准*:assets.json 每项含 reference_image 路径。\n2. **分配别名**:按出场顺序给资产分配 ``/``,写入 assets.json 的 alias 字段;全片别名映射唯一且不变。\n *完成标准*:别名映射表生成。\n3. **写进提示词**:每镜素材定义段声明本镜用到的别名;保留关系段抄资产卡视觉锚点。\n *完成标准*:抽任一镜,别名与 assets.json 一致。\n4. **画风检查**:漫剧/真人风格只出现在画风规范字段,人物描述无风格词污染。\n
