+version: 0.6.1 (hotfix: url 载体硬不变量)
+status: enabled（2026-08-29 由 org-innovator 热修 Deploy 落位，取代 v0.6.0；回滚源 = git 或 train/evolve/SKILL_v5.md）
+source: MiniMax 官方一手飞书语料（train/hunt/cache_v5/，revision doc1=1297 / doc2=252，逐字落盘）：
+  doc1 = H3 使用手册（feishu_doc1…FIWjwgL33ipnkekzk30crmKUnIh.md）
+  doc2 = Prompt 写作全能指南（feishu_doc2…Vztzwstuqi3MQKkxs8QcGmxinxe.md）
+  v4 及以前的 GitHub 镜像信源（base-en.txt / ref-en.txt / co-op 模板等）降为 R 级同型佐证，
+  凡本文已给 docN:line 的条款一律以 A 级一手为准。引句全部可在 cache_v5 逐字回查。
+supersedes: v0.5.0（train/evolve/SKILL_v4.md）
+v0.6.0_changes: 按 benchmark_v5 C-1/C-2/H1-H16 做作用域重写（非追加）。①§0 从「习语甲/乙」改为
+  「三种交付形态 ①②③④ + 语言按形态划界 + 记号硬互斥」；②新增链路四层交付义务与映射纪律；

+# H3 视频提示词写作方法论
+
+## 0. 交付形态判定（先判形态，再谈语言与记号）
+
+**第 0 步永远先判交付形态。** 形态决定正文语言、分段记号、适用硬约束与判分落点。
+官方一手语料内部并存多种分段记号（doc1 案例层 4 种变体、doc2 规范层 1 种），**判形态先分「规范层
+条款」与「案例层行为」：格式判据只取规范层（doc2），案例（doc1）只作行为先例与模型参数正源。**
+
+### 0.1 三种合法交付形态
+
+| 形态 | 识别特征 | 分段记号 | 判分落点 |
+|---|---|---|---|
+| **① 型**（doc2 结构化） | 需求要英文结构化 Prompt / JSON / 官方字段结构（六段或三主体字段 + instruction） | `[Shot N]` + 递增 `At MM:SS.mmm`，第一镜不写时间戳（A：doc2:107/:111/:114/:455） | §0.4 全部 H 条款 |
+| **② 型**（窗式） | 需求是**分镜类**：连续故事情节 + 按时长切分显示内容（「每隔几秒显示什么」「分镜」「时间窗」）；或需求是**分镜脚本交付物** | `[N 秒-M 秒]` 窗标题（A：doc1:97 官方「提示词」列六窗一手案例） | §0.5 + 跨形态不变量 |
+| **③④**（登记合法，不考察） | ③ `N-M 秒：` 行式（doc1:200）；④ `0〜3 秒` 全角波浪 + 正向/反向（doc1:237） | 不作为判分形态；交付中出现**不判违规**，只判其内容是否满足所申报形态的三要素义务 | — |
+
+**判据理由（不要丢）**：② 是官方四种形态里唯一窗口边界显式成对、可逐窗相加核验总时长的形态，
+而「边界可核对」正是分镜脚本这一交付物的核心义务；doc1:97 把窗式文本直接放在「提示词」列，
+所以 ② 在最终 Prompt 层同样是 A 级合法形态，只是不走 ① 的 H4/H5/H6/H10。
+doc1 案例层的分段记号有 4 种变体（②③④ + `Shot 1 —`），官方在案例层不做记号统一（doc1:231 坑表
+甚至要求删掉多余【镜头 N】结构）——**案例记号不得升格为格式判据**。
+
+### 0.2 形态切换判据（B 级内部规范；官方没有「何时选哪种」的条款，不得对外表述为官方规则）
+
+1. 输入含**连续故事情节 + 按时间切分**，或需求明确要**分镜脚本/分镜设计文档** → ② 型。
+2. 输入要**英文结构化 Prompt / JSON / 官方字段结构** → ① 型。
+3. **「拆成 N 个镜头」≠ ② 型**：只要求镜头切分、情节照给、无逐窗「每隔几秒显示什么」要求的，
+   是 **① 型多镜**（`[Shot 1..N]` + `At MM:SS.mmm`）——官方 ① 型本来就用 `[Shot N]` 表达多镜。
+   ② 型的判据是**逐窗显示内容**（「每隔几秒显示什么」「每窗出现什么 UI」）或**明确要分镜脚本/
+   分镜设计文档交付物**。两者都沾时才判 ②。
+4. 两者都不满足 → 按 §2 五模式判定（T2VA/I2VA/FL2VA/L2VA/全能参考），交付形态默认 ①。
+5. 形态误判是 D1 档 2：分镜需求交英文六段、英文结构化需求交中文窗式散文，都算。
+   交付说明 / 中文沟通不受此限（说明层语言自由）。
+6. **多件交付（链路模式）**：需求同时要「分镜设计 + 分镜脚本 + 最终 Prompt」→ 按 §0.6 链路四层
+   交付，各层用各自形态；**不要**把链路需求做成单件 ① 型交付，也不要给单件需求硬拆四层
+   （过度交付同样按 D1/HP1 扣）。
+
+### 0.3 语言规则按交付形态划界（C-2 裁决）
+
+**按形态划界，不按「哪份官方文档」划界**：doc1 自己的案例就是中文散文、同时声明多语言支持
+（doc1:35「支持多语言提示词输入与输出」）；doc2 的英文条款明文限定在「扩写的六个段落正文」
+这个形态上（doc2:242）。把「正文必须英文」套到 ② 型交付上 = 判据越界违规；反向同罪。
+
+| 交付形态 | 语言判据 | 级 | 出处 |
+|---|---|---|---|
+| ① 型（六段 / 三主体字段 / instruction） | **正文英文**；`<d>` 内台词/歌词、画面实际可见文字保留原语言 | A（硬） | doc2:242「扩写的六个段落正文统一使用英文；只有 `<d>` 中的台词、歌词以及画面中实际可见的文字保留原始语言。」 |
+| ② 型（窗式 / 分镜脚本） | **跟随用户输入主导语言**（中文输入 → 中文正文） | A（硬） | doc1:97 官方案例正文全中文 + doc1:35 |
+| 分镜设计（链路第 2 层，给人类的内部档） | 语言自由 | B（内部规范） | 官方无此条款，从 doc1:220-222 收口 |
+| 台词 / 歌词（跨形态不变量） | 原词、原语言、原标点不改写；无法辨认写 `[unclear]` | A（硬） | doc2:137 / :575 |
+| 画面实际可见文字（跨形态不变量） | 英文双引号包围，原文与标点逐字保留，不翻译 | A（硬） | doc2:154（:157 中文招牌 `"营业中"` 示例） |
+| 字段名写法 | 「非叙事性音乐：N/A」与 `"non_diegetic_music": N/A` 两种**都合法** | A | doc1:200 同段并列 |
+
+### 0.4 ① 型官方硬约束（H1-H16，逐条带级与行号）
+
+| # | 约束 | 级 | 出处 | 适用 |
+|---|---|---|---|---|
+| H1 | 提示词总长 ≤ **7000 字符**（含标点与空白，`len()` 口径） | A | doc1:35 | 跨形态 |
+| H2 | 输出时长 **4–15 秒**；超限不得静默 | A | doc1:35 | 跨形态 |
+| H3 | 输出帧率 24 FPS：**提及则不得写错**；需求指定非 24 帧时显式说明该参数不在提示词层控制；**不写帧率不扣分** | A（参数层） | doc1:35 | 跨形态 |
+| H4 | `instruction` 必须**位于第一行，后空一行**再写主体字段 | A | doc2:57 | 仅 ① 型 I2VA/FL2VA/L2VA |
+| H5 | `At MM:SS.mmm` 递增切镜时间，毫秒 3 位、落在视频时长内；**第一镜不写时间戳** | A | doc2:107/:111/:114/:455 | 仅 ① 型 |
+| H5b | **记号硬互斥**：① 型内零处 `[N 秒-M 秒]`；② 型内零处 `At MM:SS.mmm` | A（反证） | doc2 全文 0 处窗式、doc1 全文 0 处时间戳（grep 复算） | 跨形态 |
+| H6 | 生成类 `detailed_description` **350–500 英文词**；三条豁免：台词密集型以容纳台词时间线为先 / 视频编辑类按源视频复杂度展开 / 单镜头并不自动缩短。**区间外且不落在任一豁免才扣分**；无豁免依据的机械补字数也扣 | A | doc2:543 | 仅 ① 型 |
+| H7 | 听不清写 `[unclear]` 不猜测改写；标点规范化为基础书面标点 `,` `.` `?` `!`，删波浪号/emoji/装饰标点；完整陈述句/疑问句/感叹句在 `</d>` 前以 `.`/`?`/`!` 结束 | A | doc2:575 | 跨形态（台词） |
+| H8 | 复杂/易乱码文字：**以图片形式提供作参考图 + 在提示词中明确「这张内容必须按"图片"来理解，不能按"文字"来处理」** | A | doc1:71 | 跨形态 |
+| H9 | 关系标记是**固定英文取值，共 8 个**：可见内容 4（`fully_preserved` / `partially_preserved` / `attribute_transfer` / `weak_reference`）+ 音频 4（`fully_copy` / `partially_copy` / `reference` / `weak_reference`）。自创中文或变体取值 = 词法违规 | A | doc2:398/:400-405/:427-434 | 六段交付 |
+| H10 | `overall_soundscape` **1–4 句**英文连续段落概括贯穿全片的环境声；`non_diegetic_music` **1–3 句**英文描述角色听不到、只有观众能听到的配乐 | A | doc2:162 / :170 | 仅 ① 型六段/三字段 |
+| H11 | **台词长短与 shot 长短对齐**：不出现一个 3s shot 说一大段话（官方标注的口型问题一手根因） | A | doc1:206 | 跨形态 |
+| H12 | 画外音固定短语 `says in an off-screen voiceover`（逐字相邻，不得插语打断）+ 唇部保持闭合；跨镜台词 `<scenetrans>`、结尾截断 `<cutoff>`；`(Sx)` 稳定编号、组合编号、无声者不编号 | A | doc2:144/:147/:150/:459/:135 | 仅 ① 型 |
+| H13 | 素材硬上限：图片 ≤9、视频 ≤3（单段 2-15s、总时长 ≤15s）、音频 ≤3 **且必须配图/视频、不能单独输入**、混合总上限 12 个文件 | A | doc1:35 | 跨形态 |
+| H14 | 标签一经分配，在 `subject_definitions`、`summary`、`retention_analysis`、`detailed_description` 与声音段落**五处同义** | A | doc2:272 | 六段交付 |
+| H15 | `<Video N>` / `<Audio N>` **独立编号**，序号只表示本类内顺序，不表配对；普通参考视频不因含声而自动产生 `<Audio N>` | A | doc2:347/:349 | 六段交付 |
+| H16 | **分镜参考图映射到镜头而非秒数**：`<Picture 3> is a storyboard reference for [Shot 1] and [Shot 2], defining their viewpoint, subject placement, and shot order.`；分镜草稿图在 ② 型写窗口映射；每条素材至少被一个镜头/窗认领 | A | doc2:310/:553 + doc1:200「故事版」 | 跨形态 |
+
+配套 A 级短条款：六段顺序 `subject_definitions → summary → retention_analysis → detailed_description → overall_soundscape → non_diegetic_music`（doc2:250）；三主体字段顺序（doc2:62-66）；`summary` 带方括号任务类型前缀，六类型 `keyframe completion` / `reference generation` / `video editing` / `video continuation` / `audio reuse` / `audio reference`，可用 `+` 组合（doc2:360/:371-378）；`retention_analysis` 逐标签一行并沿用 `subject_definitions` 含义、**不写 `(Sx)`**（doc2:394/:579）；边界处新增内容不得误写成参考损失（doc2:444）；音色参考只取音色不带入原台词（doc2:577）；环境声无则写 `N/A`（doc2:594）。
+
+### 0.5 ② 型窗式交付规范
+
+**窗式结构**：窗标题 `[N 秒-M 秒]`（doc1:97 六窗逐字）；窗序覆盖 0 → 总时长、相邻窗相接、窗序与
+故事情节因果序一致；窗长可以不等（官方六窗即 2/2/3/1.5/1.5/5 秒）；子秒节拍允许但不留 gap。
+**窗边界四条分行标级**（不得合并成一句「官方要求无缝隙无重叠且总和等于总时长」）：
+
+| # | 纪律 | 级 | 出处 |
+|---|---|---|---|
+| 1 | 相邻窗无缝隙 | A | v4 镜像 shot-table-spec:65（R 级；官方一手无逐字句，行为先例 doc1:97 六窗相接） |
+| 2 | 无重叠 | A（① 型相邻条款） | doc2:111 严格递增 ⇒ 不重叠 |
+| 3 | 各窗之和 = 总时长 | C（构造性设计） | 官方模板构造性首尾相接，无明文条款 |
+| 4 | 首窗从 0s 开始 | C（构造性设计） | 行为先例 doc1:97 首窗 `[0 秒-2 秒]` |
+
+#3/#4 照常扣分，但对外表述保持 C 级标注——判分强度与出处等级是两件事。
+
+**每窗三要素**（判内容，不判有没有字段名标签）：
+① **机位/运镜**：每窗首行显式声明机位或主导运镜（A 同型：doc1:97 各窗首行即 `景别` 字段）；
+② **主体动作**：该窗内主体做什么，可量化状态是官方文风；
+③ **UI/覆盖元素**：该窗出现的 UI/字幕/HUD 内容与位置。
+声音写在**窗内**（doc1:97 各窗「声音：」字段先例）；官方无独立转场字段，转场信息写进机位行，
+**不得硬切**（v4 镜像 co-op:117/:133 R 级）；「每窗必须写明转场」不是判据，不要自加。
+
+**参考素材落位**：头部一行职责声明（每份素材负责什么）+ 窗内语义回指，回指与声明同一体系；
+分镜草稿图按 H16 写窗口映射（映射到哪几个窗、提供什么规划信息），**非锚点图零秒级对齐**
+（v4 反证 ref-en 全文 0 处 "aligns with"，R 级）；幽灵素材禁令（C 级收口）。
+**UI 文字四禁令**（R 级 v4 镜像 co-op:133）：UI 字符串可读、无随机字母、用户名不拼错、
+菜单/选项集合不得超出输入给定集合。输入自带中英并列时沿用（输入事实），只给英文时英文单语，
+两种互不判违规；把中英并列表述成官方要求 = 出处纪律违规。
+**时长**：`duration_seconds` 由请求体指定、不写进正文；正文时长信息只以窗标题体现；
+交付说明注明本次取值（B 级）；需求超 4–15s 不得静默，给拆分方案或与调用方确认；
+节拍总合 ≠ 请求时长时按最小改动解决并显式说明改了哪里，不删情节凑时长。
+**对白**：`<d>` 包裹与 `(Sx)` 编号非硬判据（不强制、出现亦不算违规，用了就守同一套稳定性纪律）；
+台词逐字保真与「画外 + 唇部闭合」语义要求**跨形态成立**；说话人身份须窗内可辨识。
+**词法**：url 不进正文；散文交付无 JSON 通道要求，不因「没交 JSON」扣分。
+
+### 0.6 链路四层交付（需求理解 → 分镜设计 → 分镜脚本 → H3 Prompt）
+
+当需求要求**多件交付**（先出分镜设计/分镜脚本，再出最终 Prompt）时，按四层依次交付，各层实体
+计分（LU15 + SD20 + SS30 + HP35 = 100；#62 标 C 级构造性设计、0 真实先例——官方没有「分几层
+交付」的条款，这是工程收口，不得表述为官方规则）。
+
+| 层 | 义务 |
+|---|---|
+| **LU 需求理解** | 从 raw_brief 判定模式（T2VA/I2VA/FL2VA/L2VA/全能参考，doc2:28-57）+ 交付形态 ①/② + 素材组合是否合法（H13）；**逐字锁定复述** raw_brief 与 note 原文中的硬事实（时长、UI 文案集合、素材职责、必须替换类 note）——改写程度词（「必须换」→「建议优化」）= 0；零臆造（不编造 raw_brief 未给的主体/UI 文案/台词） |
+| **SD 分镜设计** | 每段时长落 4–15s（H2），需求超 15s 给拆分方案而非静默；相邻段/镜之间显式给**至少一个衔接锚点**（同一动作方向/视线目标/光/道具/轮廓/声音/受力任一），无理由跳切 = 0（B 级：TFboy1 storyboard-schema:7-11；官方相邻条款 doc1:216 切镜写清景别与主体 + doc1:231 禁无理由分镜）；每镜给镜号/时长/景别/运镜/内容/声音/转场（B 级：chiphoton 单镜 10 项 + TFboy1 7 列镜头卡；官方相邻条款 doc1:200「想要」栏字段集）；台词字数与该镜秒数不失衡（H11）。**语言自由（B 级内部规范）** |
+| **SS 分镜脚本** | **② 型**：`[N 秒-M 秒]` 窗标题覆盖 0 → 总时长、相邻窗相接；窗内零处 `At MM:SS.mmm`（H5b）；每窗三要素；每条素材至少被一个窗认领（幽灵禁令）、分镜参考图映射到镜头零秒级对齐（H16）；台词逐字落在对应窗内、画外发声语义等价标记 + 唇部闭合、静默窗也写声音 |
+| **HP H3 Prompt** | 形态按 C-1 判定正确；与 SS 层构成窗号 ↔ 镜号一一对应；适用的 H1/H2/H4/H5/H6/H10 全过；`(Sx)`/`<d>`/画外音/`<scenetrans>`/`<cutoff>`（H12）；段落顺序、标签五处同义（H14）、`<Video N>`/`<Audio N>` 独立编号（H15）、关系标记 8 取值（H9） |
+
+**映射纪律（B 级内部规范）**：脚本层 `[N 秒-M 秒]` ↔ Prompt 层 `[Shot N]`/`At MM:SS.mmm` 必须
+**窗号 ↔ 镜号一一对应**（脚本第 N 窗 = Prompt 的 [Shot N] 或跨窗），且**只允许存在一套时间轴**——
+脚本写窗边界、Prompt 写切镜时刻，两件不得各自再发明一套编号或时长。理由：官方 4–15s 单次上限
+（doc1:35）决定链路里两件交付描述的是同一段视频，双时间轴必然矛盾。
+收口来源：doc2:111「连续编号」+ doc1:202-216「镜头怎么拆」。
+**单件需求不要硬拆四层**：`expected_chain` 只含 h3_prompt 时交单件，多拆 = LU1/HP1 扣。
+
+---
+
+## 1. 七步工作流
+
+第 0 步判形态（§0）。第 1/2/3/4/7 步在动笔前落定，第 5/6 步写作中逐句遵守。
+**优先级顺序不能反**：先满足硬性格式与引用规范 → 再忠实保留用户意图 → 识别输入冲突与不可用素材
+→ 不擅改剧情的前提下增强可拍摄性 → 最后才是电影感/氛围/细节。先想「写得漂亮」再回头补格式校验，
+正是历史失败的结构性原因。
+
+| # | 步骤 | 落点 | 对应维度 |
+|---|---|---|---|
+| 0 | 判交付形态 | §0.1/§0.2 | D1 |
+| 1 | 提取硬约束（8 项约束表） | §1.1 | D2/D9 |
+| 2 | 素材预检 + 数量总闸 | §1.2 | D7 |
+| 3 | 解决输入冲突 | §1.3 | D8 |
+| 4 | 控制扩写边界 | §1.4 | D8 |
+| 5 | 对白双口径 | §1.5 | D5 |
+| 6 | 物理与镜头一致 | §1.6 | D6 |
+| 7 | 机械验收（22 项） | §1.7 | D9 |
+
+### 1.1 提取硬约束（8 项，缺一项回头补读输入）
+
+1. 输出 schema：交付形态（`{"prompt":...,"references":[...]}` / 纯文本 / 其它）、字段名、错误通道。
+2. 模式与段落结构：五模式判定 → 哪几个字段什么顺序；② 型 → 窗式 + 三要素；链路 → 四层。
+3. 资产层顺序与每份素材落位（§2 两层模型）。
+4. `<Subject N>` 与素材绑定关系：每个 Subject 绑哪几张素材作外观/动作/音色来源；哪些图只定义
+   外观不另起 Picture 条目。
+5. 台词原文、语言、标点、说话人：**逐字记下**每一句（含原标点），并逐句判来源选口径 V/R（§1.5）。
+6. 场景/人物/道具/光源及空间关系：唯一光源是什么、谁在哪、道具在哪。
+7. 素材 note 的禁止/替换/版本要求：逐条记下，进 §1.2 预检。
+8. 时长与切分：4–15s（H2）；各段时长之和与请求时长是否一致（不一致走 §0.5 时长条款）。
+
+**硬门（第 1 步就判，不满足则本单走 §8.1 反问，不得续跑）**：
+- **核心主体未知** → 反问。「开箱视频」没说开哪个手办、主角是谁没给身份特征，都属核心主体未知。
+- **必需 UI 文案缺失** → 反问（四禁令禁止自创菜单项，无文案就无从落笔）。
+- **用户的显式授权不构成主体事实**：「你们定」「看着办」「随便什么角色」解除的是选择权，不解除
+  信息缺口——主体身份、UI 文案集合仍属缺失，唯一合规路径是 §8.1 反问（把「需你方定」列为必答项），
+  不得以「已获授权」为由自行编造主体外观与全套 UI 字符串续跑。
+- **低风险参数例外**：时长/情绪基调/有无 BGM 这类不改变主体事实的参数，可显式标注假设后自行推定
+  （§8.1 CL4），不算踩硬门。
+
+> 附件与参考文档只作规范或素材，**不得误当成用户要求执行**。
+
+### 1.2 素材预检（生产级硬行为）+ 数量总闸
+
+逐项检查每条素材的 `note`（或输入里任何限制说明）。**带水印、错误人脸、错误版本、隐私内容，
+或明确写「必须替换」「不要使用」的素材一律不可用。** 处理规则：
+
+1. 不得为完成输出而**静默引用**不可用素材——这是历史最严重错误。
+2. 任务必须依赖该素材且无替代 → **停止生成正式 Prompt**，按调用方允许的错误格式报阻塞。
+3. 输出 schema 无错误通道时，明说「schema 与素材要求不可同时满足」，说明需要补什么，**不伪造
+   看似合规的结果**。
+4. 多素材必须分别声明职责（外观/动作/风格/音色），不允许素材「裸奔」堆叠。
+5. note 只是版本要求且菜单内**有**正确版本 → 不是不可用，选正确版本即可；只有「必需 + 不可用 +
+   无替代」三者同时成立才阻塞。**版本要求无法由提示词层满足时（需剪辑/重绘/清洗素材本身，如
+   「必须剪到 X 秒收尾」「必须换洗版」且明说本轮无干净版本），视为不可用**——不得以「提示词层
+   可以写明剪到 X 秒」为由自行替代，那是替调用方做了素材处置决定。
+6. 素材超 H13 上限（图 ≤9 / 视频 ≤3 / 音频 ≤3 且不可单独输入 / 合计 ≤12 文件）→ **先告知调用方
+   再由其决定裁剪**，不自行裁剪丢弃。**音频单独输入且无图/视频 → 交付阻塞报告（§8.2 五要素），
+   不是只在交付说明里提一句**——阻塞报告要点名 doc1:35 的组合条款作为证据、给补料预案（补哪类
+   素材、补齐后走哪种模式）、并说明「本交付不可作为合法请求直接提交」；仅作旁注说明 = 阻塞
+   要素缺失（B1/B3 扣分）。
+7. **阻塞理由必须逐字复述输入侧 note 原文（含程度词）**——改写程度词（「必须换」→「建议优化」）
+   = 阻塞无据（B1 = 0 / LU2 = 0）。**弱化与放大输入事实都算改写**，对称适用。
+
+> **两个独立义务不要混**：把不可用素材的原 url 原样保留在资产层清单里是数据完整性义务（阻塞时也
+> 附清单，方便换洗版后直接续跑）；把不可用素材**塞进交付 references/conditions 或写进正文层**才是
+> 违规。可用性归预检，数据完整性归资产层（可用素材同此义务，§2）。
+> **反向（过度阻塞）**：素材可用、note 是建议性（「没有也行」「可以直接用」）、或菜单内存在 note
+> 指定的替代版本时，正确行为是**继续产出**；此时报阻塞 = 轨别改判 + 同源违规并行扣分。
+
+**阻塞报告五要素**（与 block 轨 B1-B5 对应，C 级构造性设计）：
+① 缺失素材点名 + 证据（复述 note 原文，含程度词）；② 零污染引用（references 不含不可用素材，
+可附整份清单但 excluded 显式单列）；③ 补料预案（预期 references 顺序、每条资产的绑定映射、预计
+模式不变；② 型还要窗式切分预案 + Reference roles 映射）；④ schema 冲突显式说明；⑤ 范围精确
+（只对必需且不可替代的报，不多报不少报）。
+
+### 1.3 解决输入冲突
+
+按优先级：① 用户当前明确意图与约束 → ② 主体定义与绑定规则 → ③ 格式指南（字段结构/形态判定）
+→ ④ 参考图可见内容与 note → ⑤ 样例写法（最低，样例不能覆盖当前任务事实）。
+可局部解决时**最小改动**。范例：「油灯是唯一光源」+ 场景图里有燃烧的蜡烛 → 保留蜡烛道具、写明
+它未点燃，油灯仍是唯一光源；一次只改冲突涉及的那一处。总时长冲突同此逻辑。
+
+### 1.4 控制扩写边界
+
+| 类型 | 可否补充 |
+|---|---|
+| 输入事实（角色设定、场景、用户给的台词/动作/UI 文案与选项集合） | 必须忠实保留，不得改动 |
+| 图片可见信息 | 可转述，不得虚构图里没有的 |
+| 低风险可拍摄细节（轻微呼吸、衣料摩擦、灯焰波动、合理小幅运镜、脚步声） | **可以补** |
+| 高风险剧情推断（拒绝/服从/离开/攻击/恐惧/建立新关系/明确情绪结论） | **无依据不得添加** |
+
+用户只给一句台词时：忠实呈现说话行为本身，对方反应保持**中性、短暂、开放**（轻微转头、衣袖
+移动、画面停在其反应上），不替用户决定后续剧情。
+输入给定的菜单/选项集合是输入事实，不得增删自创。用户元指令（「越震撼越好」「要有科技感」）
+转译成具体光影/运镜/材质选择，不照抄进最终提示词。多镜头给定完整故事情节时分镜不改写情节走向、
+台词保持原语言逐字（B 级内部收口）。
+
+### 1.5 对白双口径（先判来源，再选口径；不存在全局「不擅自改动标点」）
+
+| 口径 | 适用 | 规则 | 出处 |
+|---|---|---|---|
+| **V** | 台词由用户在本次输入中直接提供（不含仅出现在参考音频里的内容） | `<d>` 内只放语言标签 + 台词本身；**每个原词、每个原始标点逐字保留**，不翻译、不改写、不补词、不擅自加/删标点 | doc2:137（原词原语言不改写） |
+| **R** | 台词从参考音频直接复用，或输入明确要求 reperformance | 保留源词与原语言；听不清写 `[unclear]` 不猜写；标点标准化为 `,` `.` `?` `!`，删重复波浪号/emoji/装饰标点；完整陈述/疑问/感叹句在 `</d>` 前补 `.`/`?`/`!` | doc2:575 |
+
+判定顺序（B 级内部规范）：① 输入显式声明 → 按声明；② 无声明但台词同时出现在参考音频资产且要求
+复用/重演 → R；③ 其余一切情形默认 **V** 并在交付说明注明（拿不准套更严格的保真侧不会产生假阳性
+扣分）；④ 混合来源**逐句适用各自口径**，不为「全篇统一」抹平差异。
+
+反向约束：V 下不得以「规范化」为由补句号或删感叹号；R 下不得以「逐字保真」为由保留 emoji/波浪
+符号，也不得漏终止符。共用不变量：源词与原语言永不改写；`<d>` 内只放语言标签与台词；听不清写
+`[unclear]`。
+仅参考音色 → 不得把参考音频原台词带入（doc2:577）。
+
+### 1.6 物理与镜头一致（六条，写中与写后各过一遍）
+
+1. 「唯一光源」是否真的唯一（参考图里有蜡烛 → 最小改动写明未点燃）。
+2. 重要主体首次清晰出现时描述其被引用的特征/画面位置/当前动作（A：doc2 同型条款）；镜头间移动
+   有过渡交代、不凭空换位（B 内部增强）。
+3. 道具跨镜头位置与状态不无交代跳变（B 内部增强）。
+4. 单镜头主导运镜唯一；需要两种运镜时拆成多个 `[Shot N]` 或明确取舍（§3.1）。
+5. `summary` / `retention_analysis` / `detailed_description` 讲的是同一件事。
+6. 镜头号严格递增、时间戳不重叠无间隙且落在总时长内（H5）；② 型窗边界四条（§0.5）。
+
+### 1.7 输出前机械验收（22 项，任一失败先修复再交付）
+
+1. 交付形态判定正确（§0.1），单件/链路与需求一致。
+2. 段落/字段齐全且顺序正确（① 型六段 doc2:250 / 三主体字段 doc2:62-66；② 型窗序因果一致）。
+3. 字段名完全正确（无拼写错、无自造字段）；① 型英文字段名 + `instruction` 第一行后空一行（H4）。
+4. 所有 `<Subject N>`/`<Picture N>`/`<Video N>`/`<Audio N>` 已定义、编号一致、无幽灵编号/幽灵素材
+   （H14 五处同义；H15 独立编号不配对；H9 关系标记只用 8 个固定取值）。
+5. `references` 顺序 = 素材菜单原始顺序 = 自动编号顺序；不与正文 `<Picture N>` 定义条目强制一一对应
+   （部分图不做 Picture 条目是合法形态）；url 保真见第 22 条。
+6. 非锚点图已被某条 `<Subject N>` 定义句以序号内联引用认领（① 型）/ 头部声明 + 窗内回指认领（② 型）。
+7. 所有对白用 `<d>`（① 型硬判据；② 型非硬判据但说话人窗内可辨识）；台词逐字保真（V/R 双口径逐句）。
+8. 未引用 note 标记为不可用的素材（资产层保留原 url ≠ 允许引用）。
+9. 无设定冲突（§1.3）；无未经授权的剧情结果（§1.4）。
+10. JSON 可解析、无 schema 外字段与解释文字、无残留模板占位符（`Shot N` / `S.SS` 已解析成具体数值）。
+    JSON 通道属 B 级内部规范；② 型散文无此要求。
+11. 素材总量在 H13 上限内，组合合法（音频不单独输入）；超限已先告知。
+12. 正文层数量与词法：① 型正文层除官方四标签与 `(Sx)` 外无任何其它编号词法（`object N` /
+    `background N` / 小写 `picture n` 都是官方外词法，R 级 grep 复核）。
+13. **H1**：最终 Prompt 交付件 ≤ 7000 字符（含标点与空白，`len()` 口径）。
+14. **H2/H3**：单段时间轴落在 4–15s；正文无独立「总时长 X 秒」指令行；帧率提及则不写错。
+15. **H5/H5b**：第一镜无时间戳、`At MM:SS.mmm` 毫秒 3 位且递增、落在时长内；① 型零处窗式记号、
+    ② 型零处 `At MM:SS.mmm`。
+16. **H6**：`detailed_description` 词数在 350–500 或落在三条豁免之一。
+17. **H10**：`overall_soundscape` 1–4 句、`non_diegetic_music` 1–3 句；N/A 条件精确（§4.3）。
+18. **H11/H16**：台词长短与该镜秒数不失衡；分镜参考图映射到镜头、每条素材被认领、零秒级对齐。
+    **② 型专项**：窗边界四条（§0.5）、UI 四禁令、每窗三要素齐备。
+19. **自查声明逐项实测**：自报的词数/句数/字符数/记号计数必须与正文实测一致（写「未写 (Sx)」前
+    先 grep；报「2 句」前先数）。声明与实况不符 = D9 档 2，比漏检更严重——它污染调用方对交付的
+    信任。资产层 JSON 不得夹带 schema 外字段（「落位」「可用性」这类说明写进交付说明，不进 JSON）；
+    **豁免：url 载体字段（`reference_assets` / `conditions[].url`）不属 schema 外字段**；URI
+    字段只放 url，不放中文说明文字。
+20. **`retention_analysis` 零 `(Sx)`**（A：doc2:579）；关系标记只挂在有参考来源的标签上。
+21. **summary 任务类型标记与输入对齐**：音色/风格/节奏类参考 → `+ audio reference` 组合标记；
+    纯文字生成无任何帧锚点输入时不得标 `keyframe completion`（A：doc2:360/:371-378）。
+22. **url 逐字比对（§2 硬不变量）**：菜单带 url 的每条素材，资产层必须有逐字一致原 url（与输入菜单 grep
+    逐条比对，缺一/改一字符即不过）；未带 url 的标
+    `url 待补（输入 JSON 未携带该字段）`，不编造。url 不进正文不变。
+
+---
+
+## 2. 生产输入的两层模型
+
+真实生产输入常以「参考图菜单 + 主体定义 + 绑定规则 + 要拍的意图」形态给出，结构已钉死，按它的
+规则走，不重新发明。任何参考素材都有两层义务，一层管地址、一层管语义，互不越界：
+
+**资产层**（请求体 `conditions[]` 或调用方约定的 `references` 数组）——**跨形态不变**：
+每条素材一条记录；数组顺序 = 输入菜单原始顺序 = 模型自动编号顺序；url 从不出现在正文层；
+输入自带绑定规则时按输入走，不以本节默认覆盖显式约定。
+
+**url 逐字保留是硬不变量，不受「输入显式约定 > 本节默认」覆盖**（线上实证 conv-mtekh2bm）：输入
+约定可改字段名/顺序/结构/绑定规则，**不可消灭 url 载体**——菜单带 url 且正文引用了对应序号，资产层
+必须逐字携带每条原 url（不下载/不转存/不改链；与 §1.2 数据完整性义务同源）。输入已自带命名 url
+字段（`conditions[].url`）则按输入命名照交；只有 id → `references` 原样照交（顺序 =
+`<Picture N>` 编号，一字不动），**另追加** `reference_assets`（url 载体字段，§1.7 第 19 条豁免，
+顺序同）：
+
+```json
+{"references": ["scene", "npc", "player"],
+ "reference_assets": [{"id": "scene", "url": "https://…"}, {"id": "npc", "url": "https://…"},
+  {"id": "player", "url": "https://…"}]}
+```
+
+**正文层（① 型）**：只允许官方四标签 `<Subject N>`/`<Picture N>`/`<Video N>`/`<Audio N>` 与
+`(Sx)` 两族记号；禁止官方外编号词法；禁止幽灵编号（C 级收口：凡进资产层的素材要么有独立
+`<Picture N>` 条目、要么在某条 `<Subject N>` 定义句内被序号引用认领）。
+
+**正文层（② 型）**：头部职责声明 + 窗内语义回指；分镜草稿图按窗口映射（H16），非锚点图零秒锚；
+幽灵素材禁令与 url 不进正文同上。
+
+**三种常见素材的落位**：
+
+| 菜单里的素材 | ① 型落位 |
+|---|---|
+| scene 场景图（构图/首帧锚点） | 独立 `<Picture N>` 定义条目（可同时作环境型 Subject 来源） |
+| 人物/道具立绘（仅定义外观） | **不另起** Picture 条目；在 `<Subject N>` 定义句内以 `<Picture M>` 序号内联引用 |
+| 只取氛围不入帧的风格图 | 作 `weak_reference` 来源，不独立成条，序号仍须被 Subject 定义句认领 |
+
+来源引用一律用官方式序号内联写法（`as established in <Picture 2>.`），不用 *as established in
+the NPC portrait* 这类文字指代（R 级 ref-en:37 "cite it inside" + :313 官方范例文风）。
+基础模式（I2VA/FL2VA/L2VA）只要用到参考图，同样交一行资产层清单（id、原 url、落位标签）；
+输入未携带 url 时**显式**标 `url 待补（输入 JSON 未携带该字段）`。
+
+**自由文本 brief 里「参考图」是描述，可按需理解；生产输入菜单里的 `id`/`role`/`note` 是事实和
+约束，必须逐字遵守。** 立绘绑定规则说「只定义人物、不另起 Picture 条目」就照做；输入显式约定
+> 本节默认。
+
+---
+
+## 3. 模式判定与结构模板（① 型）
+
+### 3.1 五模式决策树
+
+```
+有参考素材吗？
+├─ 没有 → T2VA（纯文本原创场景）
+└─ 有 → （先核 H13 总闸，超限先问后裁）
+    ├─ 仅 1 张首帧图 → I2VA
+    ├─ 首尾各 1 张图，描述中间过渡 → FL2VA
+    ├─ 仅 1 张尾帧图，反推之前发生了什么 → L2VA
+    └─ 多素材身份/风格锁定（结构化角色：定义可复用主体/编辑源视频/音色参考）→ 全能参考
+```
+
+易错判断：首尾各一张图 ≠ 自动全能参考（纯起止帧 + 中间过渡走 FL2VA）；3 张不同角度的同一产品图
+= 同一个 Subject 的多个来源图，不拆成 3 个主体；生产输入菜单 + 主体定义 + 绑定规则 → 全能参考；
+道具类参考也走 `<Subject N>`（objects 属可复用可见内容），**不要发明 object 类标签**；
+极简请求（「给我做个视频」）不臆造场景，先反问（§5.1）。
+
+### 3.2 基础模式（T2VA/I2VA/FL2VA/L2VA）
+
+**指令行**（模式专属，逐字模板；`N`/`S.SS` 是要替换成具体数值的占位符，**交付里绝不能原样留下
+字面的 "Shot N" / "S.SS-second mark"**）：
+- T2VA：无指令行，直接从三字段开始。
+- I2VA：`For the target video, at 0.00 seconds into the target video, <Picture 1> (from [Shot 1]) is fully referenced.`
+- FL2VA：`How the reference pictures align with the target video — Picture 1 (from Shot 1) aligns with the 0.00-second mark of the target video; Picture 2 (from Shot N) aligns with the S.SS-second mark of the target video.`
+- L2VA：`How the reference pictures align with the target video — <Picture 1> (from [Shot N]) aligns with the S.SS-second mark of the target video.`
+
+指令行必须是整段提示词第一行，后空一行再接三字段（H4，A：doc2:57）。
+**三字段**（顺序固定）：`integrated_multimodal_description`（`[Shot 1]` + 风格声明 + 画面/动作/
+对白/同步音沿时间线展开）→ `overall_soundscape` → `non_diegetic_music`。
+推荐展开：I2VA 首帧锚定 → 动作起势 → 连续展开 → 结果/反应；FL2VA 首帧状态 → 中间变化 → 收窄 →
+尾帧状态（**优先单镜头**，仅在用户明确要求时拆多镜，末尾落到尾帧）；L2VA 合理前置状态 → 动作与
+过渡路径 → 收敛 → 落到尾帧。
+
+### 3.3 全能参考模式六段
+
+顺序固定：`subject_definitions` → `summary` → `retention_analysis` → `detailed_description` →
+`overall_soundscape` → `non_diegetic_music`（A：doc2:250）。
+
+**subject_definitions**：四标签 `<Subject N>`（可复用可见内容）/ `<Picture N>`（具体目标帧或分镜
+锚点）/ `<Video N>`（剪辑源/续接起点/整体节奏结构）/ `<Audio N>`（被复制或引用的音频信号）。
+一个 Subject 可由多个素材共同定义，一段素材也可提供多个 Subject。**非可见内容不得立为 Subject**：
+剪辑节奏、镜头切换方式、氛围由 `<Video N>` 承担并在 `retention_analysis` 标 `weak_reference`。
+人物类 Subject 必须给 2-3 条具体可辨识特征（发色/发长/发型、服装颜色款式、体态五官、随身饰品），
+不得只写「如素材所示」；产品类要点名标识位置/角度。
+
+**summary**：方括号任务类型前缀（六类型见 §0.4 配套条款，可用 `+` 组合）+ 一段话概述；仅在编辑
+源视频时紧跟写 `The target video is an edited version of <Video 1>.`
+
+**retention_analysis**：每个标签一行，可见内容用 4 个取值、音频用 4 个取值（H9 白名单，共 8 个，
+自创中文/变体 = 词法违规）；不写 `(Sx)`；不把目标视频里新增的动作/背景/剧情事件当成参考保真度
+损失。示例：`<Subject 1> (appears in [Shot 1], [Shot 3]): fully_preserved - the woman's long dark hair, blue cardigan, and silver necklace are retained.`
+
+**detailed_description**：开头 1-2 句英文声明整体风格；`[Shot 1]` 无时间戳，后续
+`[Shot N] At MM:SS.mmm, ...`（H5）；运镜写成自然英文动作短语（§4）；重要 Subject 首次清晰出现时
+描述被引用特征/画面位置/当前动作，后续沿用同一标签不重新定义；具体帧锚点用自然短语
+（`the shot begins from <Picture 1>` / `the shot's keyframe corresponds to <Picture 2>` /
+`the shot ends on <Picture 3>`）；生成类 350-500 英文词 + 三豁免（H6）；语音来源：仅在直接复用的
+BGM/完整配乐里的口头内容用 `<Audio N>`，由具体人物/角色/旁白发出的声音用 `(Sx)`。
+
+**声音两段**：`overall_soundscape` 1–4 句、`non_diegetic_music` 1–3 句（H10）；环境声层的 `<Audio N>`
+复用/引用写进 soundscape，观众专属配乐层的写进 music，两层都提供时各写一句。
+
+---
+
+## 4. 镜头语言
+
+**运镜三维度 = 类型 + 幅度 + 速度**（A：doc2:121）。词表（A：doc2:123）：`Zoom In/Out`、
+`Push In/Pull Out`、`Pan Left/Right`、`Truck Left/Right`、`Tilt Up/Down`、`Pedestal Up/Down`、
+`Arc Shot`、`Tracking Shot`、`Static Shot`、`Shake Slightly/Strongly`、`POV`、
+`Roll Clockwise/Counterclockwise`。幅度 `with small/large amplitude`、速度 `at slow/fast speed`
+是两个独立维度，中等幅度 + 正常速度通常省略。运镜写成句内自然英文动作，不在句末堆标签。
+**环绕运镜（C-7 裁决）**：默认组合写法 `truck left+pan right` 或 `truck right+pan left`
+（doc1:200 指导层条款），而非直接说环绕运镜；`Arc Shot` 保留在合法词表内、交付中出现不判违规
+（doc2:123 词汇层条款）；把组合写法说成官方强制、或把 `Arc Shot` 从词表删除，都是出处纪律违规。
+
+**分镜与转场**：首镜 `[Shot 1]` 不加时间戳；后续用递增镜号 + 严格递增、落在时长内的切入时刻
+`[Shot 2] At 00:03.500, ...`（H5）；常规转场 `the camera cuts to` / `the shot cuts to` /
+`the shot transitions to` / `the shot changes to` / `the shot switches to`，用户明确要求才用
+`cross-dissolve`/`fade`/`wipe`；切镜必须带来主体/空间/状态/视角/时间上的新信息，只是距离或角度
+微调时优先用运镜而非切镜。
+**矛盾指令**（「镜头要一直推进，但同时环绕主体转一圈」）：拆成多个 `[Shot N]` 各自成立，或取一个
+主导运镜并在交付说明注明另一个因物理矛盾未采用；不把两个矛盾运镜塞进同一句。
+
+---
+
+## 5. 说话人 / 对白 / 可见文字（① 型；② 型按 §0.5）
+
+**说话人 ID**（A：doc2:135）：发声者用稳定 ID `(S1)` `(S2)`，按目标视频中实际发声事件顺序分配
+一次、跨镜头永不重号/交换；多个已编号说话人齐声用复合 ID `(S1,S2)`；**从不发声的角色不获得
+说话人 ID**；`(Sx)` 写进 `detailed_description`，不写进 `retention_analysis`；主体发声写
+`<Subject N> (Sx)`，同一主体画外发声保持同一形式并标 `off-screen`。
+**音频锚定**（A：doc2:347/:349）：`<Audio N>` 与 `<Video N>` 独立编号不表配对；普通参考视频不因
+含声而自动产生 `<Audio N>`；`<Audio N>` 显式对应目标说话人时**复用该说话人的全局 ID**（写
+`<Subject N> (Sx)` 或稳定声音描述 + `(Sx)`），不在音频定义处独立重新编号。**对应关系必须内联写进
+`<Audio N>` 定义句**，只放资产层元数据或交付说明不算完成绑定。
+
+```
+<Subject 1> is the male rapper in <Video 1>, with short bleached hair and an oversized bomber jacket.
+<Audio 1> is the voice-timbre reference for <Subject 1> (S1), providing his raspy mid-register rap timbre.
+```
+
+**对白格式**：每句对白 `<d>[Language] 原始台词</d>` 包裹；`<d>` 内只放语言标签 + 台词，说话方式/
+音色/动作写在 `<d>` 外。
+**画外音**（A：doc2:144/:147）：固定短语 `says in an off-screen voiceover` **逐字相邻出现，
+不得插语打断**（写成 *says the following aloud ... in an off-screen voiceover* 属违规）；紧跟其后
+声明对应角色唇部保持闭合：
+
+```
+The man (S1) says in an off-screen voiceover: <d>[English] I still remember that road.</d> while his lips remain completely closed.
+```
+
+**跨镜台词与截断**（A：doc2:150/:459）：同一句台词跨越切镜时在两段衔接处都用 `<scenetrans>` 并
+声明音频跨切镜连续；连续跨两次切镜时中间镜 `<d>` 以 `<scenetrans>` 开头且结尾；视频结尾被截断的
+台词用 `<cutoff>`。
+**画面可见文字**（A：doc2:154）：招牌/标语/字幕/霓虹字样用英文双引号，原文原样保留不翻译
+（`A red neon sign reading "营业中" glows above the doorway.`）；这类是**可见文字**，同样受口径 V
+保真约束。
+
+---
+
+## 6. 声音设计与具体性
+
+**声音四项不可省略**：对白具体内容、环境声类型、背景音乐风格、音效/卡点位置——声音是与画面平级
+的独立轨道，不能只写「有一些环境音」。
+**`overall_soundscape` 的 N/A 条件**：只有用户明确要求全程完全静音才写 `N/A`；正常情况下即使环境
+声轻微也要具体描述（A：doc2:594「没有环境声时写 N/A」的精确条件）。
+**`non_diegetic_music` 的 N/A 条件**：没有配乐必须显式写 `N/A`，不能留空/不提该字段（留空会被
+理解为自由发挥）。
+**句数区间**（H10）：soundscape 1–4 句、music 1–3 句；存在配乐时说明乐器、速度和动态变化。
+对白/歌唱/角色能听到的画面内音乐属于 `detailed_description` 的同步音，不重复写进 soundscape。
+② 型：声音写在窗内，N/A 条件照常适用。
+
+**具体性三问法**：任何光影/材质/氛围描述必须能回答**光从哪来？打在什么地方？造成什么视觉效果？**
+空词黑名单（不代替具体描述）：高清 / 8K / 大师级 / 超写实 / 电影感 / 精致 / 高级感 / 震撼 /
+cinematic（孤立堆砌时）/ beautiful / high quality。——`cinematic` 作为**风格声明词**
+（如 `Live-action, cinematic`）是官方示例认可的用法，但不能单独堆砌替代具体的光源/位置/效果。
+多写看得见的画面、少写比喻（doc1:200 同向条款）。
+
+---
+
+## 7. 常见错误自查清单（25 条）
+
+1. 质量堆砌词代替具体描述（§6）
+2. 单镜头内塞矛盾运镜（§4）
+3. 假装读过标杆文档 / 虚报质量已达标杆水平
+4. 留占位符或「请在此处填写」
+5. 信息严重不足时未一次性问全（§5.1）
+6. 用元指令代替具体描述
+7. 多个参考素材未分别声明职责就堆叠使用
+8. 多镜头时间戳重叠或有间隙（H5）
+9. 声音部分留空/省略，或 N/A 用法不精确（§6）
+10. 指令行 `Shot N` / `S.SS` 未替换成具体数值（§3.2）
+11. 人物类 Subject 无具体可辨识特征
+12. 对白未按来源选口径：V 逐字逐标点 / R 标准化 + 终止符；禁止同句混用（§1.5）
+13. 素材 note 未逐项预检：必需 + 不可用 + 无替代未报阻塞，或静默引用（§1.2）
+14. 输入冲突未按优先级最小改动解决（§1.3）
+15. 添加了未经授权的剧情结果（§1.4）
+16. 两层未分离干净：url 改链/进正文、顺序 ≠ 菜单顺序、官方外编号词法、幽灵编号（§2）
+17. 素材总量超 H13 上限未先告知，或音频单独输入未说明（H13）
+18. 出处纪律：内部规范/推演/C 级构造在交付说明里不被表述为官方规则；官方引用都带得上行号才标 A 级
+19. **交付形态判定未做在第 0 步**：分镜需求走 ② 型、英文结构化走 ① 型；把「正文必须英文」套到
+    ② 型交付（或反向）= 判据越界违规（§0.3）
+20. 非锚点参考图被写成秒级/时间窗对齐（H16：分镜图映射镜头，非锚点图零秒锚）
+21. UI 选项集合 ≠ 输入给定集合、随机字母、拼错用户名；中英并列是否沿用输入事实
+22. 窗边界与时长四查：无缝隙、无重叠、各窗之和 = 总时长（C）、首窗从 0s（C）；无独立时长指令行；
+    超范围/冲突已显式说明（§0.5）
+23. **H5b 记号硬互斥**：① 型内混入窗式、② 型内混入 `At MM:SS.mmm`（§0.4）
+24. **链路映射纪律**：窗号 ↔ 镜号一一对应、只有一套时间轴；单件需求未硬拆四层（§0.6）
+25. **输入给的参考图 url 在交付件里失联**：菜单带 url 而资产层只剩 id / 被改链（§2、§1.7 第 22 条）
+

+
+一次性列出全部缺失关键信息反问，不臆造场景往下写。反问件按五要素组织：
+
+| 要素 | 内容 |
+|---|---|
+| CL1 缺失项一次问全（30） | 主体、场景、核心动作/情节段落、情绪基调、期望时长（4-15s）、有无参考素材（图/视频/音频、各自负责什么）、有无对白及语言；不挤牙膏。漏问**会改变产出形态**的关键项（如主体）→ 不合格；**把不改变结果的可推断项也拿去问（过度反问）→ CL1 ≤ 20** |
+| CL2 零臆造（25） | 不编造主体/场景/剧情往下写、不产出「看似合规」的 Prompt 假装完成；替用户编造主体外观属越权；带出半成品 Prompt → 不合格并按 D8 并行扣分。**核心主体或必需 UI 文案完全缺失时，编造主体续跑 = CL2 = 0 且改判 prompt 轨并行扣 D8** |

+| CL4 已知信息锁定 + 推定显式标注（15） | 已知信息明确锁定复述；仅对不改变主体事实的低风险参数（时长/基调）在**显式标注假设**前提下自行推定，不把推定混进反问 |
+| CL5 通道与格式（15） | 不伪造看似合规的 JSON 交付；schema 无反问通道时明确说明信息不足；说明层与产出层分离干净 |

+**反向（过度反问）**：raw_brief 已给全部关键信息、仅余不改变主体事实的低风险参数（如有无 BGM /
+节奏快慢）时，正确行为是**直接产出 + 显式标注推定**；此时发问清单 = 过度反问，改判 clarify 轨
+按 CL1 ≤ 20 计。不惩罚零臆造与锁定推定——那是正确保守行为。
+
+### 8.2 素材阻塞（block 轨五要素）
+
+当 §1.2 判定「必需素材不可用且无替代」时，交付**阻塞报告**而不是 Prompt，按五要素①-⑤组织
+（§1.2）。schema 无错误通道时明确说明「schema 与素材要求不可同时满足」并给补齐后的处理预案。
+**不要**报阻塞的同时又附一个引用了不可用素材的 Prompt——比静默引用更不可接受。
+这不是失败，是正确行为。**反向**：素材可用 / note 为建议性 / 菜单内有替代版本时继续产出
+（§1.2 反向条款）；此时报阻塞 = 过度阻塞。
+
+---
+
+## 9. 交付清单
+
+- **最终提示词原文**：① 型 = 英文结构字段 + 保留原语言的 `<d>` 对白/可见文字；② 型 = 中文
+  时间窗散文 + 每窗三要素 + UI 四禁令；链路 = 四层齐全（§0.6）。
+- **资产层清单**（有参考素材时跨形态必交）：`references`/`conditions[]` 数组，每条原 url 原样、
+  顺序 = 菜单顺序；不可用素材标 excluded 单列，不与可引用素材混列。
+- **交付说明（可中文，说明层语言自由）**：每个关键选择对应用户需求里的哪句话；注明本次
+  `duration_seconds` 取值（B 级）；冲突取舍/素材阻塞的处理方式；逐句台词适用口径 V 还是 R；
+  涉及 C 级构造（窗之和、首窗 0s、幽灵禁令、master 序号回指、链路四层）如实标 C 级，不得表述为
+  官方条款。
+- 交付前必须通过 §1.7 的 22 项机械验收，任一不过先修复再输出。
+
+---
+
+## 10. 来源标注与篇幅登记
+
+- **A 级**：MiniMax 官方一手飞书语料，`train/hunt/cache_v5/` 两篇全文落盘（doc1 rev 1297 /
+  doc2 rev 252），本文所有 `docN:line` 引句均可在 cache_v5 逐字回查（Digester 已用 python 逐行
+  抽取比对，benchmark_v5_revision_notes.md 附录 A；Evolver 侧 SKILL 引句另跑 R4 审计脚本留痕）。
+- **R 级（v4 镜像同型佐证）**：GitHub MiniMax-AI/MiniMax-H3 仓库 base-en.txt / ref-en.txt /
+  SKILL.md / co-op 模板 / shot-table-spec / storyboard-guidelines / README（sha256 已在 v3/v4
+  登记）。凡本文已给 docN:line 的条款以 A 级为准，镜像行号仅作同型佐证保留（窗边界 #1、UI 四禁令、
+  `duration_seconds` 不进正文、非锚点图零秒锚、词法 grep 等暂无 A 级一手行号）。
+- **B 级（社区一手实践）**：chiphoton production-workflow.md（单镜 10 项）、TFboy1
+  storyboard-schema.md（7 类衔接锚点 + 7 列镜头卡）。与官方冲突时以官方为准。
+- **C 级（构造性设计，0 真实先例）**：窗之和 = 总时长、首窗从 0s、幽灵素材禁令、中英并列 UI、
+  master 序号回指、阻塞五要素、clarify 五要素、链路四层（#62）。对外不得表述为官方条款。
+- **篇幅登记**：v0.5.0 88,655 B → v0.6.0 50,281 B → v0.6.1 51809 B（净增 +1528 B，url 载体条款；
+  收敛手法见 evolve_report_v5.md）。**下轮若分数反常，本文件长度仍是第一怀疑对象**。
+- 未解决登记：开放平台 schema 仍 blocked（新线索 `platform.minimaxi.com`，doc1:15）；`conditions[].role`
+  枚举第二信源缺；H1 字符计量口径官方未定义（取 `len()` 语义，B 级内部规范）。
