+# VIP98K 图片参数、参考图限制与详情替换状态修复
+
+2026-09-11，北京时间。运行修复已上线至 `ai.yydd.ai`。服务器代码版本 `b26e2650`，构建 ID `bEps6MRbyVkKLfBQTUChg`；本地对应提交 `aaa65026`。
+
+## 实测结论
+
+读取[服务商公开目录](https://api.vip98k.com/api/v2/catalog/models)及当前账户授权列表，测试其中 9 个生图模型。不含 OCR、抠图、压缩等处理工具，也不包含其他服务商。共 77 次尺寸、比例及质量调用：64 次取得结果图，13 次接口失败；另完成 1 次超过 10MiB 原图继续编辑的完整参考图处理调用。出图成功不等于尺寸或比例符合要求。
+
+[实测图片与全部记录](./qa-vip98k-0911/index.html)提供原图、实际像素、耗时、请求编号和 JSON；这些大体积验收附件保存在本地，未纳入 Git。测试使用合成蓝 A / 红 B 卡片，验证接口与返回参数，不代表复杂商品细节一致性的验收。
+
+| 模型 | 真实结果 | 本次处理 |
+| --- | --- | --- |
+| gpt-image-2-vip | 方图 1K=1024²、2K=2048²、4K=2880²；横图亦成功。2K 覆盖 9 个固定比例 | 恢复 1K/2K/4K 与比例；同步目录缺字段不再覆盖已验证能力 |
+| gpt-image-2.5 | 请求 1024²、2048²、2880² 都返回约 1254²；2K、4K 档位字符串也只返回约 1672×940 横图。9:16、4:5、5:4 成功 | 恢复比例，保留真实可用的 1K 档；不虚报 2K/4K |
+| gpt-image-2.5-flare | 三档有实图；2K 的 2736×1536 会变成 3840×2160。4:5、5:4 即使显式传 aspect_ratio，仍变成 3:4、4:3 | 修正跨档边界为 2720×1536，实收 2048×1152；保留 7 个已验证固定比例 |
+| nano-banana-2 | 方图三档 1024²/2048²/4096²；4K 横图 5504×3072 | 保留三档和比例 |
+| nano-banana-pro | 方图三档 1024²/2048²/4096²；4K 横图 5504×3072 | 保留三档和比例 |
+| gpt-image-2 | multipart edits 方图 2K 成功；初测超大尺寸遇到 502/503，调整后 2K、4K 横图成功 | 记录原生 edits 证据；网站尚未启用该 multipart 线路，未偷偷改为其他接口或模型 |
+| gpt-image-2.5-sunburst | 三档成功；2K 横图同样存在升到 4K 的边界现象 | 保持网站原有隐藏状态 |
+| nano-banana-2-lite | 双参考与无参考各一次均 HTTP 400 | 保持不可选 |
+| nano-banana-fast | 双参考与无参考各一次均 HTTP 400 | 保持不可选 |
+
+覆盖方式：各模型基础调用；可成功的主要线路补测三档方图及高分辨率横图；VIP/Flare 补测 2K 的全部原有固定比例，并对异常做对照。不是每个模型、每个比例、每个档位的完整笛卡尔积测试。
+
+普通 GPT Image 2.5 的 2K/4K 不是“没公开所以推断不支持”，而是实际请求已接受、实际像素未提高。VIP 与 Flare 的 4K 方图是 2880²；不能把所有模型的 4K 都解释为 4096²。
+
+## 为什么界面连 1K 都消失
+
+目录缺少尺寸和比例数据时，原同步规则回退到“1K、auto”；此外，简洁参数面板把比例和分辨率放进同一数组，并按 `aspectRatio:imageSize` 去重，导致“auto”覆盖了“1K”按钮。
+
+已拆成“比例”和“分辨率”两组，修正各自选中状态，并在收起后的按钮上显示当前分辨率。按验证结果更新了现有 5 个 VIP98K 模型的尺寸、比例能力，保留模型价格、启停状态和既有业务配置。Flare 的 4:5、5:4 因反复偏离请求未继续展示。
+
+## 10MiB 只约束送入服务商的参考副本
+
+网站上传上限是 20MiB；用户报错描述的是服务商单张参考图 10MiB。这不限制生成结果原图，也不会为了 10MiB 改写结果原件。
+
+实际闭环：
+
+- 将本次成功生成的 10,622,997 字节结果原图保存在对象存储。
+- 使用修复后的真实服务商适配器，把它作为下一次生成的参考图。
+- 生成 JPEG 参考副本 451,639 字节；准备阶段约 17.5 秒；完整测试约 83.2 秒并成功返回新图。
+- 下载原件核对 SHA-256，内容完全未变。
+
+统一覆盖外部图片地址、Data URL 和无默认 S3 配置分支；压缩失败停止提交，不再透传原始字节。压缩后检查字节上限，新缓存命名空间隔离历史未校验对象，缓存 HEAD 校验大小。仅参考副本沿用原有最长边 1920 策略，完整保留画面；结果原图归档流程未增加 10MiB 限制。
+
+## 张华的三次详情替换与页面一直处理中
+
+会话 `0f1c5be0-4522-4300-abcb-a93e17a60001`，三次都重跑“拼合切片 2”，实际使用 `gpt-image-2.5-flare`，每次提交 2 张参考图。
+
+| 北京时间 | 总耗时 | 前置识别 | 生图调用阶段 | 结果 |
+| --- | ---: | ---: | ---: | --- |
+| 13:24:30–13:25:07 | 36.483s | 27.070s | 8.773s | HTTP 400 |
+| 13:32:06–13:33:14 | 67.919s | 14.824s | 52.337s | 两次 502 后 HTTP 400 |
+| 13:34:33–13:34:56 | 23.114s | 13.750s | 8.305s | HTTP 400 |
+
+第二次有 15 秒和 30 秒重试等待，共 45 秒。参考图准备分别 394ms、2ms、0ms，不是上传大图造成这三次等待。
+
+这些记录中的图片是失败后展示的参考图。原代码把回退参考图保存进 GeneratedImage 并递增成功数，造成“日志里有图片”的误导。现在失败保留清楚提示，但不再记作成功生成；没有删除历史三条记录。
+
+页面另有独立缺陷：
+
+1. 工作区没有消费后台 `data-appendMessage` 结果事件。
+2. 历史同步只比较消息 ID，可能忽略同一消息的内容更新。
+3. 进行中状态依赖流状态或结果数量，重跑旧卡片、并行乱序以及失败附带参考图时会判断失误。
+
+已补齐结果事件处理、按请求 ID/卡片 ID 判定结束、内容同步、失败结束状态。切回页面、网络恢复和 pageshow 触发历史同步；所有目标卡片结束后主动关闭遗留流连接并清除本地“处理中”。旧的本地待处理记录也能从历史恢复。
+
+没有证据证明张华当时一定切换过浏览器。后台标签页可能延迟前端刷新，但不能据此代替上述已确认的代码原因。
+
+## 服务商 400 仍有未确认因素
+
+原三次日志没有实际 size、quality 与服务商请求编号，无法追溯并确定是哪一个字段导致拒绝；也没有证据把用户贴出的 10MiB 错误与这三次绑定。
+
+修复已记录尺寸、比例、质量和 `x-request-id`。上线后另一次 VIP 调用出现 400，但同质量合成测试成功。Flare 后续的高、中、自动质量都出现过 400；同一路线此前大量自动质量调用成功，中质量亦有成功。因此没有把“高质量不支持”当成定论，也未据此隐藏质量选项。对照请求号及结果保存在实测记录中，可交给服务商定位。不能承诺已经消除服务商自身的拒绝或波动。
+
+## 上线与验证
+
+- 42 项相关单元/回归测试通过；包含真实大于 10MiB 图片压缩、损坏数据拒绝、模型路由、像素边界及历史恢复。
+- 浏览器使用真实 AI SDK 验证：结果乱序、失败附图、流保持打开、恢复历史后的状态结束；真实参数组件验证 4K/16:9 切换和仅 1K 时按钮不丢失。
+- TypeScript 与生产构建通过。候选版本首页/登录页 HTTP 200，受保护模型/聊天 API 返回预期 401，风格化页返回预期认证跳转；生产域名检查通过。
+- 先将新请求切到候选实例，等待原主进程连接归零后更新主实例，再将新请求切回主实例。保留旧静态资源，避免已打开页面加载旧分块失败。
+- 回滚构建：服务器 `backups/next-before-vip98k-0911`；模型配置备份：`backups/vip98k-sizing-0911-1789109819739.json`；Nginx 原配置：`backups/vip98k-nginx-0911.conf`。
+
+已经打开的页面需要刷新一次载入新前端。之后切回浏览器会主动补同步，无须靠反复刷新判断是否完成。

+# 阿里云万相视频测试（2026-09-16）
+
+按“先用阿里云的视频测试”执行。沿用红色咖啡杯参考图与推进镜头提示词，真实调用阿里云百炼北京线路；只测试 `wan2.6-i2v-flash` 首帧生视频，未改线上默认模型，未部署。
+
+## 实际结果
+
+| 环节 | 结果 | 说明 |
+|---|---|---|
+| 原“千问视频”凭据 | 401 / invalid_api_key | 该配置下没有模型；不是已可用的视频线路 |
+| 现有“阿里云”官方凭据 | 可用 | 用现有配置进行测试，没有展示或提交密钥 |
+| 阿里云直接请求 | 成功，41.888 秒 | 任务 `ba336392-6ddb-41f0-8db5-33af2ab41396`，包含 10 秒轮询间隔；不是精确服务商计算时长 |
+| 本站 `/api/canvas/generate/video` | 成功，39.166 秒 | 独立新任务 `593dced8-36e0-4a9a-8b3b-ff90abd603ff`；实际使用万相，未走 Veo |
+| 成片文件 | 通过解码检查 | H264、1280×720、5.000 秒、1,118,864 字节；按请求生成无音轨视频 |
+| 画布自动转存、刷新播放 | 本轮未验收 | 本地数据库隧道出现 CONNECT_TIMEOUT，画布读取超时；恢复后刷新时浏览器连接关闭。不能沿用上一轮 Veo 的浏览器通过结果作为万相本轮通过证据 |
+| 画面效果 | 尚不达标 | 2 秒抽帧出现大小两个杯子叠影；提示词要求保持单个杯子，不能把接口成功当成产品一致性达标 |
+
+## 本轮接入
+
+新增独立万相画布适配器，调用官方 `video-synthesis` 创建异步任务，再用任务 ID 查询；生成成功交给已有画布转存流程。不改旧聊天视频 Provider 的行为。
+
+模型筛选仅开放已接入的 `qianwen-video / wan2.6-i2v-flash`。配置采用首帧模式、720P/1080P、2–15 秒整数、随参考图比例。单图精确传入 `img_url`；显式传入分辨率、时长和音频开关，不再依赖旧 Provider 的默认参数。首尾帧、多参考、外部音频、其他万相版本不因此标为已支持。
+
+本轮相关回归共 35 项通过（34 项批次通过，随后新增 1 项错误处理检查并重跑 6 项适配器测试通过），源码 TypeScript 检查通过。覆盖提交参数、只读轮询、任务失败、无产物不成功、未实现模型不出现在候选中。未运行完整生产构建。
+
+官方参数依据：[阿里云万相首帧 API 文档](https://help.aliyun.com/zh/model-studio/legacy-image-to-video-api-reference/)。本轮真实请求只覆盖 5 秒、720P、无声，其他官方支持参数没有逐个付费生成。
+
+## 隔离范围与证据
+
+本地工作树在 `codex/video-canvas-parity-0916`。数据库专用 schema `codex_wan_20260916` 只覆盖测试用 AiProvider/AiModel，复用现有官方凭据；生产 public 模型与服务商配置未修改。使用专用 QA 账号和测试画布。
+
+原始证据位于 `.qa/video-aliyun/`：`direct.jsonl`、`canvas-result.json`、`media-probe.json`、`wan-canvas.mp4`、`wan-frame.png`、`tests.log`、`typecheck.log`。临时签名地址、账号凭据和原始环境文件不提交 Git。
+
+阿里云任务在当前请求内轮询，275 秒内未完成会带任务 ID 报超时；尚未增加持久化任务队列或刷新后续查。当前通过范围是官方直连与本站完整生成 API，不包含浏览器一键生成到刷新恢复的完整闭环。
+
+收尾已禁用专用测试账号并撤销会话，删除本轮隔离模型 schema、临时凭据，停止本轮开发服务及数据库隧道。未改生产服务商 Key 或模型默认项。

+# 阿里云音频与导演台扩展实施记录
+
+日期：2026-09-17。此记录接续 video-canvas-task-repairs-2026-09-17.md。
+
+## 已完成代码
+
+- 语音/音乐节点从仅上传改为官方模型选择、文本、音色、语言、格式、指令和歌曲参数。控件严格跟随所选模型能力，千问3 TTS 不发送其不支持的数值音调/速度参数。
+- 阿里云 HTTP 适配：qwen3-tts-flash、qwen3-tts-instruct-flash、qwen-audio-3.0-tts-flash/plus、fun-music-v1。北京限定模型不能错用国际服务地址；使用原服务商密钥，不给浏览器返回密钥。
+- 音频加入持久任务队列。先记录供应商原文件，再下载校验 WAV/MP3 并归档；转存失败只恢复下载，网络受理状态不明不会自动再次生成。
+- 导演台 AI 识图入口：调用当前视觉理解模型，把参考图转为人物/立方体/球体和机位组成的可编辑简化布景。结果独立保存，允许显式插入或替换原对象。不是精细纹理/网格重建，也没有凭空生成 GLB。
+- 对象轨道包含位置、旋转、缩放、可见性、启用开关、线性/缓入缓出插值、逐帧时间编辑/删除、自动记录、秒/30fps 显示单位、时间轴缩放。旋转按最短弧插值；对象删除清理轨道；修改总时长同步缩放轨道。
+- 相机与对象共用播放头和导出时间；跟随相机采样运动后的目标对象。纯对象动画也可预览和导出。场景骨骼动作序列、声音轨道、跨机位自动切镜尚未实现。
+- 修正浏览器 crypto.randomUUID 失去调用上下文导致记录帧/插入布景报 Illegal invocation；修正视频编码器立即停止可能丢掉末帧，预热首帧并留出末帧呈现时间。
+
+## 48 服务器配置
+
+已使用 `scripts/configure-aliyun-canvas-audio.cjs --apply` 写入现有阿里云官方北京服务商，保留其他模型和全局默认设置；变更前模型记录备份在应用目录 `.model-config-backups/`（不含服务商密钥）。
+
+- qwen3-tts-instruct-flash：启用，音频页面优先顺序 900。
+- qwen3-tts-flash：启用，顺序 901。
+- fun-music-v1：已建配置，禁用，标记 activationRequired，等待账号邀测权限确认。
+- Qwen Audio 3.0：适配已写，当前 Key 的只读 models 目录未列出，未盲目启用。
+- 千问3.8既有视觉理解配置保留。
+
+只读调用官方模型目录返回 HTTP 200，包含千问3 TTS/指令版；未发起真实付费语音/音乐/识图生成。模型目录可见性不能代替生成效果验收。
+
+[千问 TTS 官方文档](https://help.aliyun.com/zh/model-studio/qwen-tts-api)；[新音频 HTTP 文档](https://help.aliyun.com/zh/model-studio/cosyvoice-tts-http-api)；[Fun-Music 官方文档](https://help.aliyun.com/zh/model-studio/fun-music-api)（邀测、北京地域、临时文件 24 小时）。
+
+## 验证
+
+- helpers 全套 475 项通过；追加总时长/删除对象轨道用例后导演台 24 项通过，合计覆盖 476 项。
+- TypeScript `tsc --noEmit --incremental false` 通过。
+- `scripts/qa/video-canvas-audio.cjs` 使用实际服务适配器和本地替身：请求参数、归档前检查点、存储失败后零重复 POST、链接过期、服务商错误、租约丢失均通过。
+- `scripts/qa/video-canvas-task-db.cjs` 实际临时 PostgreSQL 验证通过：并发幂等、独占领取、恢复与失效 worker 隔离。
+- 本地浏览器调用实际 React 组件和 Three.js：音频能力控件、未开通音乐拦截、对象播放头/关键帧编辑/帧单位、独立对象动画视频导出、重建结果插入/替换通过，无浏览器运行错误。模型与上传返回使用本地替身。
+- 真实浏览器录制文件经 ffprobe 确认为 VP9、1280×720；设置 2 秒，文件约 1.974 秒。提取首尾帧确认对象实际移动。MediaRecorder 属于实时录制，受浏览器帧调度影响，不能宣称离线逐帧精确编码。
+
+参考站及开源自动剪辑算法详见 `video-canvas-smart-edit-research-2026-09-17.md`。该部分为已完成研究和实施方案，尚未接入完整自动混剪服务。
+
+部署状态：本次生产环境仅更新上述模型配置；应用代码在开发分支完成，未发布到生产应用。

+
+本记录接续 [上一轮真实测试](video-canvas-real-test-2026-09-16.md)。独立工作树本地验证，沿用真实服务商和数据库配置，使用专用测试账号；没有启用模拟接口，没有修改真实用户画布或默认模型。
+
+## 本轮完成的功能
+
+| 功能 | 与 LibTV 对照的缺口 | 本轮实现与验证 |
+|---|---|---|
+| 视频提示词优化 | 原入口只提示后端待接入 | 新增真实文字模型接口；默认沿用管理员配置的官方千问 3.8，可选择已有文字模型，预览编辑后应用；真实优化 HTTP 200 |
+| 视频提示词翻译 | 原入口只提示后端待接入 | 中英文双向翻译；保留素材引用；真实翻译 HTTP 200，浏览器填回通过 |
+| 提示词结果编辑 | 应用后旧文字与新结果叠加 | 修复 contentEditable 与 React 更新冲突；浏览器实测应用后只剩新译文 |
+| 弹窗交互 | 缺少完整模态交互 | 使用现有 Dialog 组件，焦点约束、Escape 关闭、取消请求、失败保留原文、禁止空结果应用 |
+| 视频时段剪辑 | 只记录范围，不输出成片 | 按源视频实际时长定位，FFmpeg 导出独立 MP4，保留音轨，创建关联结果节点；真实 8 秒片源导出 4 秒新片通过 |
+| 视频画面裁剪 | 上轮仅处理函数通过 | 本轮完整下载、处理、上传 HTTP API 通过，输出 640×360、8 秒新片 |
+| 视频音轨拆分 | 上轮仅处理函数通过 | 完整 API 输出独立 AAC 音频和无音轨 MP4；不冒充人声/背景音分离 |
+| 本地音视频上传 | 原来只存 blob 地址，刷新失效 | 新增真实上传接口和媒体探测，保存对象存储地址；MP4/M4A 上传通过，伪装 MP4 被拒绝；最多 125 MiB、10 分钟 |
+| 上传状态恢复 | 中断后可能一直等待 | 显示上传中/失败，恢复旧 blob 或未完成上传时明确要求重新上传 |
+| 脚本/画面分析长时间等待 | 旧 SDK 参数被类型断言掩盖，缺少调用时限 | 改用 maxOutputTokens，脚本预算 12000、视频分析 2200、其他分析 1600；150 秒推理时限、175 秒页面请求时限、关闭 SDK 自动重试；空白/截断/非 JSON 结果不再冒充结构化成功 |
+| 项目加载失败 | 失败后还可能继续编辑未就绪画布 | 加载超时和失败显示重试，加载成功前阻止编辑，避免保存覆盖 |
+
+## 真实调用结果
+
+本地开发编译、数据库隧道和接口前置处理均计入 HTTP 耗时，不代表生产模型纯推理时间。
+

+
+文生视频请求走自动匹配，响应确认实际使用 `veo-3.1-fast`。此次成功更新了上一轮该模式失败的状态，但不证明其他模式或每次调用均成功。生成接口本次返回服务商地址，其长期留存尚未验收；与本轮修复的用户上传文件持久化是两个环节。
+
+本机代理对媒体域名使用保留网段 DNS。完整媒体 API 测试仅在开发进程对两个已知媒体域名使用经服务器解析的公网地址；生产安全下载器的 IP 校验和 SSRF 防护没有放宽。
+
+## 页面回归与边界
+
+- 官方千问翻译弹窗成功显示结果，应用后只保留新译文；保存重试成功后刷新，重新选择节点仍为同一译文。证据 `prompt-after-refresh.txt/png`。
+- 本地冷编译和接口前置检查曾使保存超时，页面显示失败并允许重试；点击重试后已保存。未把本地耗时当作生产性能结论。
+- 浏览器上传自动化被文件选择器事件超时阻塞，无法完整验收“从页面选文件到刷新后播放”；真实上传 HTTP 接口已单独通过。不能将接口通过写成整个页面流程通过。
+- 58 项定向回归通过：6 项新工具契约、12 项模型/参数/媒体安全、4 项保存队列、36 项 VIP98K 相关回归。
+- 源码 TypeScript 检查通过；未宣称完成生产构建，临时 Next 生成目录不纳入源码检查。
+
+## 仍未完成
+
+音频驱动视频没有已确认可用模型；视频超清、去字幕、专业人声分离、AutoLink、智能剪辑及逐帧功能未完成全量对齐。布局与参考站相近，但本轮以真实功能闭环为主，不能称为全站像素级复刻。
+
+服务器已确认存在 `/usr/bin/ffmpeg` 与 `/usr/bin/ffprobe`。本轮代码未部署生产。原始证据保留在本地 `.qa/video-completion/`，包含 API 响应、ffprobe 信息、实际产物和回归日志；带临时媒体签名的原始响应不提交 Git。
+
+收尾：两个专用测试账号已停用并撤销活跃会话；临时环境凭据已删除；本地开发服务、数据库隧道和本轮浏览器标签已关闭。开发工具自动修改的 next-env.d.ts / tsconfig.json 已还原，主工作区未修改。

+# 视频画布逐层功能对照记录 — 2026-09-17
+
+> 后续修复见 [逐项修复和验证记录](video-canvas-repairs-2026-09-17.md)。下方为修复前基线，尤其 05-15 的截帧判断已在修复记录中纠正；不能将基线结论作为最新状态。
+
+本轮按页面 → 模块 → 菜单 → 子菜单/参数 → 实际处理代码逐层核对，共记录 **231 个检查点、10 个分组**。结论：当前本地版本的基础生成、视频处理和相机运镜已有真实能力，但离参考站完整功能与像素级对齐仍有明显差距；旧文档中“已完成/已对齐”的泛化表述不能作为验收结论。
+
+## 范围和证据口径
+
+- 参考站：[LibTV 画布](https://www.liblib.tv/canvas)，2026-09-17 当次登录可见界面。模型名、价格、入口随账号与站点更新变化，本记录是现场快照。
+- 我方：分支 `codex/video-canvas-parity-0916`，功能基线 `d5593ac3`。比较的是本地实现；本轮**未部署到 48 服务器、未重启服务**。不能据此推断线上已具备最近两轮修复。
+- 参考站实际展开了导演台、姿势、机位、群众、全景、识图导入、时间轴、路径、新脚本、图片编辑、视频、音频/音色、故事板、工具箱、素材/角色/历史/资产库、Agent、分享及快捷键。上传了一段我方合成的 3 秒无音轨 MP4，以查看视频后期面板；**未提交本轮参考站付费生成、未发布分享、未签协议**。
+- 我方本轮阅读活动入口与处理函数，并在浏览器重新打开真实 `DirectorStudioDialog`。导演台使用本地组件验收页，存储适配器是 localStorage；这不是本轮全站端到端验收。组件页使用已有构建 CSS，字体请求有回退，因此截图不能用于字体级像素验收。
+- “实测”引用本轮显示或前两轮真实测试证据，详见 [真实串联记录](video-canvas-director-chain-2026-09-16.md) 和 [运镜测试记录](video-canvas-director-motion-2026-09-17.md)。其他“接通”表示代码存在真实执行链，**不表示参考站效果一致或本轮真实调用成功**。
+- 参考原始 UI 文本与截图保存在 `.qa/video-audit-0917/`，不提交含项目上下文的原始采集。下方每组列出采集文件名线索和代码定位；只有不含个人素材的导演台对比图随文档提交。
+
+| 分类 | 检查点数 | 含义 |
+|---|---:|---|
+| 实测 | 23 | 已有实际显示/产物证据，仍以具体测试范围为限 |
+| 接通 | 35 | 代码链路存在，本轮未重新调用所有模型 |
+| 部分 | 60 | 已有部分能力，但交互、参数、流程或服务不等价 |
+| 缺失 | 70 | 缺该活动入口、处理链或专用服务 |
+| 占位 | 38 | 可见控件/状态与真实执行不相符，应优先纠正 |
+| 待验 | 5 | 参考或我方结果层未得到足够现场证据 |
+
+这些数量是“检查点”而非独立功能数量，也不是完成率。一个功能会拆成参数、按钮、持久化、结果等多项；不要用“模型可用”代替整套流程验收。
+
+## 需要优先处理的具体问题
+
+1. **脚本假完成**：示例角色/场景/道具混入真实工作流；资产进度直接显示完成；3/3 写死；新增/行操作/单镜重新合成存在空处理或只弹成功提示。
+2. **音频生成壳界面**：模型名称硬编码，选模型仅关菜单，生成按钮没有请求，调节值是静态 div，音色列表和分页也是固定数据。
+3. **历史记录不是真实历史**：当前节点不足时补示例图/视频，固定显示前 8 项，批量下载只有等待动画，删除仅隐藏当前组件。
+4. **视频参数没有全部生效**：2/4 个仍只请求一次；联网搜索和自动校验开关保存了状态但没有相应执行，不能展示成生效能力。
+5. **多角度预设不影响参数**：点击“鱼眼/俯拍/背面”等只改变 tab；生成仍使用旧数值。应让预设修改数值/提示词，并纳入提交。
+6. **3D 导演台尚未等价**：基础人偶与真实相机运镜可用；骨骼姿势、角色多轨、目标跟随、自由路径、全景与识图重建缺失。底部时间轴的布局也没有复刻。
+7. **图片参数及参考兜底仍有问题**：主图片 composer 未把清晰度传入生成请求；多张请求只提取第一张结果；无参考图时仍可能回退示例图片。需按入口修复，不能只补选项外观。
+8. **参考站已更新后期工具**：现有旧版工具栏未覆盖片段重拍、续写、主体消除、补帧和慢放。超分、去字幕、人声分离仍需专用服务。
+
+P0 指误导性成功、假参数、假历史或无法执行的活跃按钮；P1 指核心闭环与关键能力差异；P2 指布局、便利性或扩展能力。本轮只建立对照记录，没有把这些新发现冒充成已修复。本轮添加的参考站测试节点和空分组已清理，原有两张图片及连线保留。
+
+## 实际界面对照
+
+相同浏览器视口 1280×720；比较布局与可见功能，不计算不具可比性的整屏像素差异（场景内容与选中对象不同）。
+
+| 参考站导演台 | 我方当前真实导演台 |
+|---|---|
+| ![参考站](assets/video-canvas-audit-2026-09-17/reference-director.png) | ![本地](assets/video-canvas-audit-2026-09-17/local-director.png) |
+
+- 参考站左侧工具栏及场景区约 280px，右侧属性区约 280px；我方左侧约 210px、右侧约 260px，布局和工具顺序不同。
+- 参考站底部为多轨时间尺，角色和机位分轨；我方轨迹编辑在右侧下方，720px 高度首屏不可见。
+- 参考站是有骨骼关节的人体；我方默认是基础几何人偶。真实渲染成功不能据此视为角色能力对齐。
+- 我方 FOV 可显示很长的小数，旋转输入使用弧度；参考站显示简短角度值。需要统一格式、单位和控件尺寸。
+- 顶部、空节点、音频参数、素材市场等尚未做逐状态截图像素验收；此前局部测过的间距不能外推整个页面已像素级复刻。

+
+| 功能 | 当前可复用线路/能力 | 不能冒充的能力 |
+|---|---|---|
+| 分析、脚本、提示词 | 官方千问 3.8；视觉任务需视觉输入能力 | 不替代音频合成、视频超分等媒体算法 |
+| 图片生成、图片编辑、设计图预设 | 我方 GPT Image/Qwen 等兼容线路，按能力筛选 | 通用提示词生成不等于确定性图层分离、精确打光或 Topaz |

+| 3D 场景与运镜 MP4 | Three.js + MediaRecorder，不消耗生图/视频模型 | 不替代骨骼动画、识图建场景；AI 视频只接首帧和描述 |
+
+## 后续修复和验收顺序
+
+1. **先去掉误导性状态和空按钮**：脚本、音频、历史、视频多数量和高级开关、多角度预设。验收要求：每次点击有真实状态变化/请求；失败不能报成功；未接服务明确禁用；空项目没有伪造的历史与完成资产。
+2. **补核心流程数据**：脚本行编辑、资产增删改与上传、实际提示词合成、完成门槛；真实历史接口、分页、批量下载和跨刷新一致性。验收要求：新建→编辑→生成→关闭→重开保持同一真实数据。
+3. **按模型能力补音频与专业后期**：优先接已有供应商的实际类型；缺供应商时保留禁用说明。验收要求：模型选择改变请求，格式/采样率/语速等参数能在产物或请求中验证，不用参考站商标名称充当服务。
+4. **补导演台深层功能**：底部多轨、角色骨骼和姿势、目标跟随、路径编辑、全景、识图导入。每项以场景保存重载、时间轴中间帧、导出视频三处共同验收。
+5. **逐状态做视觉比对**：固定视口与相同节点内容，对空态、选中、展开菜单、错误、生成中、成功、窄屏分别截图；记录位置/大小/颜色/字体差异。当前两张导演台图只能证明存在差异，不能计算可靠“像素还原百分比”。
+
+### 尚未覆盖的结果层与条件分支
+
+- 参考站计费生成后的新脚本资产/智能剪辑/拉片完整结果、多模型收费参数分支、人像协议签署后能力、付费角色线路未执行。
+- 3 秒测试片段不足以启用参考站片段重拍；已确认 4 秒门槛，但其编辑内层仍待用合适素材复核。
+- 参考站素材目录有分页/持续更新，本轮展开分类与可见卡片，不把首屏当作完整市场目录。
+- 本地全站刷新中任务恢复、真实切换浏览器后的完成通知、全局撤销/重做、全部模型逐线路成功率，不能用代码审查替代实测。
+- 旧版脚本与发布表单内部未展开；公开发布、分享权限、协议、声音克隆提交均不属于本轮操作。
+
+这份记录可作为后续逐项关闭差异的基线；每关闭一项，应在 ID 下补提交号、浏览器证据和真实接口/产物证据，保留未覆盖条件。

+# 视频画布与 3D 导演台串联验收（2026-09-16 至 09-17）
+
+测试范围：本地隔离工作树、真实登录、真实阿里云模型与现有对象存储。未部署线上，未修改线上模型目录。临时模型目录仅含官方千问 3.8 Max 和万相 `wan2.6-i2v-flash`。
+
+## 实测发现与修复
+
+- 旧导演台只有 CSS 场景、计时器和固定示例截图。活动入口替换为延迟加载的 Three.js 导演台：对象变换、机位、真实截图、GLB 导入及场景持久化。
+- 通用上传拒绝 GLB。增加登录校验的专用接口，限制 25 MiB，验证 GLB 2.0 头部、总长度、JSON 场景和嵌入资源；明确拒绝外部纹理/缓冲区。
+- 当前七牛存储域名未提供浏览器跨域响应头，GLB 上传成功后仍无法渲染。使用现有登录保护的模型代理，并加入该存储域名的匹配。
+- 新画布首次携带节点保存时，先写节点再建父记录导致外键失败。改为事务内创建父记录、同步节点和关系、更新画布；已有画布加行锁校验版本。
+- 主视频编辑器声音开关未传给生成接口，现已传递 `generateAudio`。
+- 首帧/首尾帧快捷入口自动插入示例图片且未固定模式。改为选择画布真实图片，显式设置模式；缺少首帧/尾帧时禁止提交。
+- 裁剪尺寸一直显示固定的 1024×576，且覆盖层继承 `pointer-events: none` 导致拖框实际移动节点。恢复裁剪层交互，尺寸随选择区域与素材尺寸变化；未知尺寸时显示区域百分比。
+- 音轨卡片播放按钮只有占位提示。接入真实 audio 元素、播放/暂停、进度和错误反馈。
+- 提示词接口补充不含密钥和提示词正文的失败类型/状态码日志，便于区分模型与传输错误。
+
+## 验收记录
+
+| 步骤 | 实际结果 |
+|---|---|
+| 首次带节点 PUT 保存 | HTTP 200，节点与画布均落库 |
+| 同版本并发保存 | 一次 200、一次 409，未覆盖较新版本 |
+| 真实 3D 渲染 | 人偶与上传的橙色立方体 GLB 可见；位置修改生效 |
+| 多机位截图 | 正面 1280×720 / 40,614 B；侧面 720×1280 / 38,032 B；文件哈希不同 |
+| 场景持久化 | 数据库保存后完整刷新页面，恢复 2 对象、3 机位、2 截图、9:16 比例及模型 X=1.8/Y=0；GLB 重新可见 |
+| 千问优化 | 首次页面调用失败，原文保留；重试成功，HTTP 200 / 54 秒，结果应用到视频节点 |
+| 真实截图引用 | 节点参考缩略图 URL 与导演台截图逐一一致 |
+| 万相生成 | HTTP 200 / 35.0 秒；1280×720，5.008 秒，708,505 B，H.264 + AAC 双声道 |
+| 浏览器播放 | `paused=false`、播放时间推进、无视频错误 |
+| 自动归档 | HTTP 200 / 23.8 秒，换成持久存储地址 |
+| 剪辑 | 以正确生成视频为输入，1280×720、1.734 秒、H.264 + AAC；HTTP 200 / 32.6 秒 |
+| 裁剪 | 在剪辑结果上真实拖框，标签和导出均为 638×358，1.734 秒、H.264 + AAC；HTTP 200 / 19.8 秒 |
+| 音视频分离 | 裁剪结果生成 638×358、1.734 秒无音轨视频，以及 1.719 秒 AAC 双声道 M4A |
+| 完整刷新恢复 | 全部结果节点和 6 条处理连线恢复；独立音频与无声视频均播放成功、时间推进且无媒体错误 |
+| 代码验证 | TypeScript 源码检查通过，6 组共 40 条定向回归测试通过 |
+
+第一轮回归过程中，遗留示例节点与导演台截图重叠导致误选，生成了汽车背景视频。这轮被判为串联失败，不能作为导演台成功证据。清理旧示例后，从修复的新入口重跑，并核对真实参考 URL，再生成上述 1280×720 视频。
+
+## 能力边界
+
+AI 识图重建尚未接入，入口禁用并标明“未接通”；不再以计时器假装完成。当前验证的是基础场景与自包含 GLB，不包括复杂压缩模型、骨骼动画、完整素材库和参考站全部界面的像素验收。视频超分、智能去字幕等未配置服务的功能不计为通过。
+
+本地冷编译和 SSH 数据库连接抖动明显增加了初次加载耗时。测试中恢复连接并重试失败保存后完成后续流程；这些本地耗时不能当作线上性能结论。原提示词优化首次失败没有足够诊断信息，不能断言具体根因。
+
+## 串联顺序与留档
+
+实际画布连线为：导演台 → 真实机位截图 → 万相首帧视频 → 剪辑 → 裁剪 → 无声视频 + 独立音轨。每一步均使用上一步真实产物。
+
+本地 `.qa/video-chain/` 保存了截图、FFprobe 检查结果及实际 MP4/M4A；测试账户、密钥、签名地址、数据库快照不提交 Git。测试结束后禁用临时账户并清理隔离模型目录及临时服务。

+# 3D 导演台镜头轨迹修复与验收（2026-09-17）
+
+此前导演台只保存静态机位，运镜素材库只向提示词追加文字。静态机位截图生成视频的验收不代表连续镜头轨迹可用。本次补齐时间轴、真实 3D 播放和视频导出，未部署生产环境。
+
+## 完成的功能
+
+- 场景增加 `motion` 数据：2–15 秒、最多 100 个关键帧、相机位置、注视点、FOV、线性/缓入缓出插值和循环设置。兼容没有轨迹的旧场景；轨迹随原有画布保存链路持久化，不需要数据库迁移。
+- 支持记录、覆盖、编辑、删除关键帧及修改时间；重复时间和无效数据拦截。调整时长按比例缩放关键帧时间。
+- 推进、拉远、90° 环绕、横移预设；黄色轨迹与关键帧标记、完整轨迹总览。
+- 播放、暂停、循环、时间轴定位；预览时关闭手动相机操控。进入编辑时从当前预览机位继续，避免跳回旧机位。页面进入后台时暂停预览。
+- 导入/导出带版本号的 JSON 轨迹文件；文件限制 256 KiB，坏文件不会覆盖现有轨迹。
+- 按真实相机轨迹录制无声 MP4，隐藏网格、辅助轴和路径，支持取消；浏览器不支持 MP4 编码时明确提示更新浏览器。切到后台、关闭导演台、渲染错误或超时会停止录制并释放媒体轨道，不把部分文件当成功结果。
+- 导出结果可预览、下载、上传为真实视频节点；保存实际时长，供剪辑使用。视频上传使用现有 `canvas-video-process` 用途参数。
+- “发送首帧与运镜到视频节点”真实渲染 0 秒机位，建立导演台→首帧→视频节点连线，携带完整轨迹元数据及精简的自然语言运镜描述。模型、尺寸等继续由视频节点选择；不自动发起计费生成。
+
+## 实测中修复的回归
+
+- 使用整个关键帧覆盖机位会把关键帧 ID 写成相机 ID，导致后续 FOV 编辑失效。现在仅合并 position、target、fov，保留相机身份，并有专门回归测试。
+- WebM 原始录制缺失 duration，影响剪辑；改为 MP4。实际产物为 H.264，包含可读取的时长。
+- 预览/录制时 OrbitControls 仍可能约束相机距离；改为显式设置相机朝向，录制期间锁定交互，避免改变轨迹。
+- 从预览切换到录制时，React 更新可能重新显示轨迹辅助线；加入录制锁，确保辅助线不进入导出画面。
+
+## 验收证据
+
+浏览器使用生产组件进行本地独立验收；测试页仅将画布保存与对象存储替换成本地适配器，不伪造 WebGL、时间轴或编码结果。本轮没有调用收费 AI 模型，也未重新验证生产数据库/对象存储的整条链路；原画布持久化和真实万相链路见 2026-09-16 验收记录。
+
+| 检查 | 结果 |
+|---|---|
+| 环绕、推进与时间轴 | 浏览器真实播放，循环后仍持续播放；暂停及定位到终点有效 |
+| 轨迹总览 | 相机切换到轨迹包围盒总览视角 |
+| 自定义 JSON 导入 | 3 秒、2 个关键帧，位置与 FOV 参数生效 |
+| 坏文件导入 | 显示无效数据提示，保留原轨迹 |
+| 暂停时选择场景对象 | 预览不跳回编辑机位；场景区域像素对比无变化 |
+| 关键帧更新 | 第二帧 FOV 改为 65° 并记录，完整刷新后恢复 |
+| 首帧传递 | 从 0 秒机位生成 1280×720 PNG，回调收到首帧及 2 帧轨迹 |
+| 横屏 MP4 | 1280×720，H.264，150 帧，4.998 秒，无音轨 |
+| 播放中切换导出 | 1280×720，90 帧，3.0005 秒；从轨迹起点完整导出，画面无辅助线 |
+| 竖屏 MP4 | 720×1280，H.264，90 帧，3.002 秒，无音轨 |
+| 逐帧检查 | 对比初始、中间、结尾帧，视角连续变化，非静态图片录制 |
+| 取消导出 | 浏览器中取消后恢复按钮与编辑状态，未出现成功产物 |
+| 录制生命周期 | 自动化验证正常结束、取消、后台事件及渲染失败均释放轨道与帧回调 |
+| 代码验证 | TypeScript 源码检查通过；49 条定向回归测试通过 |
+
+浏览器自动化的多标签切换未可靠触发页面可见性事件，因此后台处理依靠事件级回归验证，不将该次标签切换算作真实后台场景通过。下载链接已接入原生下载；本轮媒体文件通过组件上传回调留档，并用 FFprobe 核验。
+
+本地 `.qa/director-motion/` 留存测试 MP4、逐帧截图与探测结果，不提交生成文件和本地测试适配器。
+
+## AI 生成与真实轨迹的边界
+
+真实 3D 导出使用配置的轨迹。当前阿里云首帧模型接入接收首帧与运镜文字，不接收可精确执行的相机轨迹参数，因此 AI 生成仍可能偏离预设，界面已明确说明。需要精确复现时使用“导出真实运镜视频”。AI 识图重建仍是独立的未接通能力，不属于本次运镜修复。

+| 参考图检查 | 同一张图作为首尾帧被去重；网络波动和链接失效都报 400 | 探测去重但保持输入位置；无效输入明确拒绝；临时连接故障报 503、失效或无权限报 400；HEAD 不成功时继续 GET 检查并释放响应体 |
+| 视频长期保存 | 画布直接保留服务商临时链接，没有进入聊天消息的归档任务 | 视频先显示，然后后台转存至现有存储，成功后自动更新画布 URL；读取视频文件并确认视频流后才上传 |
+| 转存失败恢复 | 缺少单独重试，只能重新生成 | 保留原视频及临时状态，提供“转存视频”；保存操作不调用生成模型。请求去重、并发限制、公共 IP 校验、125 MiB 下载限制沿用或补齐 |
+| 视频时长显示 | 上传与剪辑保存 durationSeconds，但播放器和剪辑栏未读取，常回退 5 秒 | 优先使用实际文件时长，短片允许不足 1 秒的真实时长 |
+
+自动转存由打开的画布触发。关闭页面前尚未完成的转存，会在重新打开、恢复临时状态后再尝试；这不是新增服务器持久化生成队列，不能保证用户离开后所有生成任务继续交付。已归档的节点使用存储地址，不依赖原服务商链接。
+
+## 真实测试
+
+| 测试 | 结果 | 证据 |
+|---|---|---|
+| 官方千问 3.8 三镜头脚本 | **通过，71.853 秒** | 返回且只返回 3 行，时长 3s / 2s / 3s，总计 8 秒，分别为外观、杯柄、咖啡液面；未虚构人物 |
+| 已生成 Veo 视频转存 | **通过，20.233 秒** | 七牛存储新地址可下载；ffprobe 为 H264 + AAC、1280×720、8 秒、1,005,090 字节，与转存前一致 |
+| 首帧图生视频复测 | **未通过，193.066 秒** | 参考图通过检查并提交生成；查询结果时上游返回 502。任务 `8aa87fb0-ef63-4f38-8930-0b1796331be4` |
+| 页面自动转存、播放与刷新恢复 | **通过** | 使用上一轮真实成片作为测试节点，页面出现正在转存状态，完成后 video.currentSrc 从 api.vip98k.com 切至 scqny.jiansun.vip；8 秒时长、播放器完整播放至 8 秒；画布保存后刷新仍使用七牛地址，readyState 为 4；本地冷编译和数据库隧道使该次转存约 2.2 分钟，不当作生产耗时 |
+| 同一任务从服务器只读复查 | **上游确认失败** | HTTP 409，`task_failed` / `Video generation failed`，请求 ID `852b2e2e-d288-47ec-8a94-9ed272f4070e`；未重复提交生成 |
+| 定向回归 | **65 项通过** | 7 项新契约 + 58 项已有回归；覆盖镜头不扩充、空行、首尾帧重复 URL、无效输入、暂时网络失败、归档成功与保留失败产物 |
+
+浏览器回归使用专用账号和写入正确画布节点格式的测试素材，素材来自上一轮真实 Veo 成片。该测试用于验证自动转存、状态持久化和刷新后媒体读取，不冒充本轮新生成。原始证据保存在 `.qa/video-followup/`，带临时签名的地址不提交 Git。
+
+## 尚未完成
+
+首帧/首尾帧/多参考视频不能因文生视频成功而全部验收；本轮首帧已拿到明确上游失败状态。音频驱动视频、视频超清、去字幕、专业人声分离、完整 AutoLink 和智能剪辑等继续保持待完成状态。没有宣称整体像素级复刻完成。
+
+另发现独立问题：对尚不存在的画布 ID 首次 PUT 且携带节点时，接口先写 CanvasNode、后创建 CanvasProject，触发外键约束失败；标准 POST 新建流程不受此特定顺序问题影响。该问题尚未在本轮修改，需另行修复并验证并发创建行为。
+
+源码 TypeScript 检查通过；专用测试账号已禁用并撤销会话，临时凭据已删除，本轮开发服务和数据库隧道已停止；开发工具生成的配置改动不提交。

+
+> 后续进展见 [继续完善与复测记录](video-canvas-completion-2026-09-16.md)：官方千问 3.8 提示词处理、Veo 文生视频、完整媒体处理 API 已出现真实成功结果。下文保留上一轮当时的测试状态。
+
+本轮按用户最新指令恢复真实调用。在独立本地工作树、127.0.0.1:3016、两个专用测试账号下运行真实接口，未启用 CANVAS_E2E_LOCAL 模拟模式。使用现有数据库配置及服务商线路；未改真实用户画布。参考站为 https://www.liblib.tv/canvas，浏览器统一为 1280×720。
+
+**结论：有视频模型，但本轮尚不能验收视频生成成功。图片生成和本地视频处理通过；保存缺陷已本地修复；仍有未接入入口。不能把模型目录可见等同于可生成，也不能把当前页面称为完整像素级复刻。**
+
+## 真实调用结果
+
+| 测试 | 结果 | 证据 / 限制 |
+|---|---|---|
+| VIP98K 当前目录 + 当前 Key 授权模型 | 两份目录均 30 个模型，视频为 `veo-3.1-fast` | 当前可用目录只有这一条视频模型；不代表服务商历史或其他账号没有其他模型 |
+| 文生视频，8 秒 / 720P | 失败，32.185 秒 | 任务受理后上游结果 HTTP 409 / Video generation failed；本站返回 500 |
+| 首帧图生视频，同参数 | 失败，23.872 秒 | 上游结果 HTTP 409 / Video generation failed |
+| 首尾帧视频，2 张图 | 失败，10.148 秒 | 上游 HTTP 503 / media service temporarily unavailable |
+| 多参考视频，2 张图 | 服务端记录失败 | 上游 HTTP 503；测试客户端随后中断，没有完整客户端耗时记录，不算通过 |
+| 服务商原始示例直接调用对照 | 失败，约 9.3 秒 | POST 202，第一次轮询 202，第二次 409，明确 `task_failed`。证明本次失败可绕过本站复现，并非仅本站参数或轮询问题 |
+| 官方 Qwen3.8 Max 文本脚本 | 失败，8.940 秒 | Access denied / account in good standing / overdue-payment |
+| 官方 Qwen3.8 Max 图片理解 | 失败，9.390 秒 | 同上，官方账户状态阻塞；未擅自切回旧模型 |
+| GPT Image 2.5 参考图产品三视图 | **通过，70.108 秒** | 本站真实图片 API 返回新图片，红杯三视角合成图；输入为人工合成测试图。此项只覆盖同链路样本，不代表所有图片预设逐个验收 |
+| 原有 Veo 成片读取 | 通过 | 只读取之前成功的任务，不计作本轮生成成功；H264 1280×720、AAC、8 秒 |
+| 成片画面裁剪（实际处理函数） | **通过，479 ms** | 640×360、8 秒、H264 + AAC，新文件 897501 字节 |
+| 成片音轨提取（实际处理函数） | **通过，81 ms** | 8 秒 AAC，197583 字节 |
+| 成片去音轨（实际处理函数） | **通过，39 ms** | 1280×720、8 秒，只有视频流，1526056 字节 |
+| 裁剪 / 拆轨完整 HTTP API | 本地环境阻塞 | 本机代理把服务商域名解析为 198.18.1.165，安全下载器拒绝该保留网段。未放宽 SSRF 防护。上述处理通过不等于完整下载/上传 API 验收通过 |
+
+直接对照任务 ID：`d3b6199d-df42-479b-bc5f-8c797f61659c`；请求 ID：`68a19660-123d-474b-aa48-cd4c6e51bed3`。可提交给 VIP98K 排查 `veo-3.1-fast` 线路。没有对失败是否扣费作假定。
+
+## 与参考站逐项比较
+
+| 项目 | LibTV 当前界面 | 本站本轮核验 | 结论 |
+|---|---|---|---|
+| 视频模型菜单 | 多个 Seedance、Kling、Wan、Hailuo、Vidu 等模型 | 只显示当前真正授权且兼容的 Veo，以及自动选择 | 匹配正确，模型覆盖范围不同 |
+| 参数 | 当前 Seedance 2.0 界面有多比例、480P/720P/1080P/4K、可调时长和音频开关 | Veo 为 16:9、720P/1080P、8 秒，菜单浏览器核验通过 | 不能复制不受当前线路支持的选项；参考菜单可见不代表每种组合都已验证 |
+| 文生 / 首帧 / 首尾帧 / 多参考 | 有相应模式，参考图数量影响可选项 | 四类请求均实测，当前上游失败 | 接口已接，产物未通过 |
+| 音频生视频 | 有入口和对应专用模型 | 当前无已启用可用音频驱动视频线路，部分入口仍待接入 | 未完成 |
+| 提示词优化 / 翻译 | 有操作入口 | 当前视频编辑器点击仅显示“后端待接入”；配置中的模型不能使入口自动可用 | 未完成，需接真实处理接口 |
+| 联网搜索 / 素材校验 / AutoLink | 三项开关可见 | 本站有前两项开关；未验证其真实执行，AutoLink 不齐全 | 不计作功能完成 |
+| 智能剪辑 / 逐帧拉片 / 导演台 | 智能剪辑、逐帧拉片 SD2.5、导演台入口 | 本站视频合成及导演台存在；逐帧拉片未完整对应 | 未完成全量对齐 |
+| 时段剪辑 | 参考有剪辑工具 | 本站记录时间范围后仍提示导出后端待接入 | 未完成；与已通过的“画面裁剪”不同 |
+| 视频超清 / 去字幕 / 人声背景音分离 | 有对应入口 | 无确认可用专用线路；普通拆音轨不能替代人声分离 | 未完成 |
+| 画布保存 | 参考可持久化工作区 | 本站原 saveCanvas 未被调用，刷新实际丢节点；本轮补自动保存、手动保存、⌘/Ctrl+S | 本地修复并通过浏览器刷新验证 |
+| 文本草稿、标题、缩放 | 应在继续编辑时保留 | 文本内容、未提交草稿、标题、50% 缩放均刷新恢复 | 本地通过 |
+| 保存冲突 | 本轮未修改参考站冲突状态 | 串行合并更新；409 停止覆盖并提示，网络错误保留脏数据供重试 | 4 项保存队列测试通过 |
+| 顶部栏稳定性 | 顶栏固定在视口 | 本站节点编辑导致原生容器滚动、顶栏移出视口；改为固定画布和 overflow-clip | 本地修复 |
+| 视觉一致性 | 深色画布、底部工具栏、节点浮层 | 布局相似，但品牌/顶部导航、底纹、图标、功能覆盖仍不同 | 局部对齐，非像素级完成 |
+
+参考账号显示 20 积分，所选视频生成界面显示 135；未充值或购买，也未在参考站提交生成。因此没有“双站同提示词成片效果”的 A/B 结果。
+
+## 本轮修复与验证
+
+- 自动保存仅在项目成功加载后启用；只有确认 404 才初始化空画布，加载失败不能覆盖原记录。
+- 画布标题、节点、连线、选择和视口统一保存，恢复时不再只恢复节点。
+- 文本编辑器草稿和模型选择及时写入节点；同项目的服务器刷新不重新覆盖本地编辑。
+- 保存采用串行队列，保存期间的新修改合并为下一次写入；失败保留状态，409 不拿最新版本号强行覆盖。
+- 保存状态可见；未保存退出时提示；切至后台尝试保存。
+- VIP98K 日志增加受理任务 ID 和失败结果状态，便于区分排队、上游失败、前端问题。
+- 12 项模型/参数/媒体安全测试 + 4 项保存队列测试 + 36 项 VIP98K 相关回归，共 52 项通过；密钥检查通过。
+- 源码 TypeScript 检查通过。Next 开发目录生成的 routes.d.ts/validator.ts 有损坏片段，单独源码检查排除了临时构建目录；未把生成文件错误隐瞒为完整生产构建通过。
+- 浏览器真实数据库保存和刷新恢复通过；本轮修复尚未部署生产。
+
+## 证据位置
+
+本地 `.qa/video-retest/`：`result-*.json` 为真实 API 结果；`provider-control-*.json` 为直接上游对照；`generated-three-view.png` 为本次真实图片产物；`local-processing-results.json` 及 `local-{crop,silent}.mp4`、`local-audio.m4a` 为处理验证；`save-*-refresh.txt` / `draft-after-refresh.txt` 为保存恢复记录；`libtv-video-parameters.png` 与 `local-video-parameters.png` 为同视口截图。原始结果可能含临时签名媒体地址，未提交到 Git。
+
+下一步阻塞明确：VIP98K 修复/提供可用视频线路；阿里云账户恢复推理权限；补齐未接入的工具，再逐项实测。未经真实产物验证的功能仍保持未验收状态。
+
+## 配置功能逐项验收台账
+
+“未单独实测”不能视为通过；已测试同链路不自动覆盖其他提示词或专用接口。

+
+后续全面验证扫描见 [2026-09-17 扫描报告](video-canvas-validation-scan-2026-09-17.md)：仍存在任务恢复、取消等未完成项，不能以本文作为全功能验收通过证明。
+
+基于 `e5b2de3c` 的 231 项对照检查继续修复。本文记录已修改的具体行为和验证边界；**不表示 231 项全部完成，也不表示与 LibTV 像素级一致**。代码在 `codex/video-canvas-parity-0916`；本轮没有部署、重启 48 服务器或修改生产数据库。
+
+## 生成与参数
+
+| 对照 ID | 修复 | 验证 |
+|---|---|---|
+| 03-02、03-06、03-33 | 主图片生成传递所选清晰度；展示每张返回图片；空参考不再注入人物示例 | 请求契约单测覆盖 1K/2K/4K、数量、空参考、多张结果；不表示各模型都支持全部规格 |
+| 03-22 | 禁用的宫格功能在创建结果前拦截，不再把示例图标记成功 | 代码检查 |
+| 04-14 | 视频 1/2/4 个对应逐个请求及独立结果节点，单项失败保留其余成功结果；重复点击拦截 | 类型与执行链检查；未付费调用 4 个视频进行验收 |
+| 02-09、02-10 | 移除未执行的联网搜索、合规素材校验开关；明确保留基础输入校验 | 代码检查 |
+| 03-12、03-13、03-32 | 多角度预设更新并提交参数；环绕角转换到 0–360、缩放 0–100 转 0–10；鱼眼和倾斜通过配置的图片模型重绘 | 单测；浏览器选择背面实际提交 180°/0°/50%；未调用模型评估角度效果 |
+| 03-14 | 明确中央图片是参考原图；去掉无执行作用的提示词开关和固定价格 | 代码检查；不宣称实时生成预览 |
+| 06-19 | 分镜视频使用配置模型及镜头时长、真实参考；未提交时显示待生成，移除 Seedance 写死与示例封面 | 代码检查；仍是创建生成器节点，需用户提交生成 |
+
+## 脚本工作流
+
+- `06-04/05/07`：表格可编辑、添加、删除和上移镜头，清空内容不会立即被默认值填回；采用画布现有保存流程。
+- `06-08/09/10/11/13`：不再注入唐朝示例角色；从脚本引用识别候选资产，类型可人工修正；支持新增、上传、引用当前画布、清除、删除、调用配置图片模型生成。
+- `06-14/15/16/17`：完成数量按真实图片和提示词计算；全局风格可编辑并参与合成；单镜和批量合成调用现有分析服务，验证镜头数量与输出字段，失败保留原内容；去掉固定第三方模型和价格。
+- `06-18`：分镜图片节点按 `@资产名` 携带准备好的参考图片；按钮文案区分创建节点与已生成图片。
+- 浏览器组件验收：修改对白、新增镜头、引用资产、修改风格，刷新后恢复；空提示词仍显示 `0/2`，资产引用后显示 `1/3`。验收页采用 localStorage 保存适配器，**不是本轮数据库端到端验收**。AI 合成、资产 AI 生成与上传仅完成执行链检查，本轮没有重复付费请求。
+- 尚未实现拖动排序、资产逐项模型/比例/数量选择、完整自动批量生成闭环。
+
+## 素材、下载和音频
+
+- `10-09/10/11/12`：面板明确范围为“当前画布素材”，只列有真实文件地址的节点，不补示例，不截断为 8/10 条，去掉虚构日期，按节点添加顺序排序。空列表已在浏览器验证。
+- `10-13`：单项、预览和批量下载调用已有下载/ZIP 接口，不再用 15 秒动画代替下载；显示 ZIP 部分失败；音频下载保留原文件，不交给图片解码器。跨域文件经现有认证下载接口处理。单测验证 WAV 字节与扩展名。
+- `10-14`：动作明确为从素材列表移除，状态随画布保存；不冒充删除源文件或跨项目历史记录。
+- `10-18`：原空资产页改为当前画布媒体列表，搜索、类型过滤、定位和下载有实际执行；工作区显示项目标题。个人跨画布资产库和 Agent 资产仍未实现。
+- `07-01…18`：未找到已实现的 TTS/音乐后端适配器，移除固定模型、假音色、空生成按钮与假调节控件。提供 `/api/canvas/media/upload` 的真实音频上传入口，保存时长，继续使用原有播放器。**这是纠正不可用入口，不是接通配音/音乐生成**。
+- `01-26/10-25`：快捷键说明只显示已绑定操作，不再列出不存在的撤销、分组等快捷键。
+
+## 视频后期
+
+- `05-15/16`：纠正上一轮对截帧的判断。旧活动处理函数实际复制封面，并硬写 1280×720；现在使用 FFmpeg 按首帧、尾帧、播放器当前时间截取真实 PNG，并探测实际输出尺寸。
+- `05-06`：新增 2/3/5 倍慢放，视频时间戳与音轨同步变速；保留音高，输出最长 10 分钟。属于普通变速，**不是 AI 补帧**。
+- `05-04/09/10/12/13`：超分、去字幕、人声/背景音分离未接专用服务，在活动工具栏明确不可用；仍保留真实音视频分离。
+- 真实本地 FFmpeg 验证：320×180、24fps、2 秒合成视频（含音轨），首帧/1 秒帧/尾帧输出不同；2/3/5 倍慢放分别约 **4.013 / 6.005 / 9.990 秒**，三份都保留音轨。集成测试用临时目录并自动清理。
+
+## 3D 导演台
+
+- `08-03/04/05/07/08/09`：对象搜索、改名、复制、显隐、锁定变换轴、等比缩放、基础对象颜色；旋转输入改为度，保存仍用弧度。
+- `08-11/13`：基础人偶改为连接肩肘髋膝的关节层级，支持 12 种姿势：站立、T 型、行走、跑步、坐姿、蹲下、招手、伸手、鞠躬、格斗、踢球、看手机。**不是参考站完整的 20 姿势、8 体型或专业骨骼编辑器**。
+- `08-15`：已加载对象只在资源、几何或外观变化时重建；单纯位置/旋转/缩放不再销毁并重新下载全部 GLB。
+- `09-01/06/07/09`：扩展至 12 个机位预设；可对准所选对象；FOV 保留两位小数；相机时间轴移至底部可折叠区域。对准是一次性定位，不是自动跟随。
+- 浏览器实际显示 T 型、招手姿势，创建正面机位与环绕轨迹，导出并通过本地上传适配器接收 **1280×720、约 2.997 秒 MP4（VP9）**。旧场景与新增姿势/显隐等数据 JSON 往返单测通过。
+- 对象多轨、自动帧、目标跟随、自由路径、全景和 AI 识图重建仍未实现。

+# 智能剪辑：参考站实测与开源算法选型
+
+检查日期：2026-09-17。本文区分实际观察、开源代码事实、建议方案与尚未实现的功能。
+
+## 参考站已观察
+
+[LibTV 画布](https://www.liblib.tv/canvas) 的智能剪辑入口有讲解视频、批量广告、口播视频、素材混剪四种预设。素材混剪预设连接七个素材节点，提示词包含卡点和突出产品，参数显示 16:9、1080P、20 秒。打开编辑器后，示例时间轴约 14 秒，含七个片段；这只是预设示例，不能当成自动生成成功的结果。没有点击收费生成。
+
+编辑器可见分割、向左/右裁剪、字幕轨道、转场、吸附、缩放、原声静音、全屏预览，导出到本地或画布。分割/裁剪会检查播放头位置与最短片段长度。界面没有公开它实际使用的后台选片或卡点算法，不能推断它使用了以下任何项目。
+
+## 已阅读的开源项目
+
+| 项目 | 可复用能力及实现 | 适用场景 | 许可证/接入边界 |
+| --- | --- | --- | --- |
+| [FunClip](https://github.com/modelscope/FunClip) | FunASR 生成转写与时间戳；把选定文字、说话人或 LLM 给出的区间映射回视频；裁剪后重排字幕时间 | 中文口播、讲解、访谈精选 | [源码 MIT](https://github.com/modelscope/FunClip/blob/main/LICENSE)，模型权重单独授权。Python/ASR 服务不能直接放进 Next 请求进程 |
+| [Auto-Editor](https://github.com/WyattBlue/auto-editor) | 按音量或运动量标记保留区间，可组合条件，前后 margin 保留呼吸和语句边界 | 去停顿、去静音粗剪 | [Unlicense](https://github.com/WyattBlue/auto-editor/blob/master/LICENSE)；低音量不是无价值内容，不能直接当产品亮点评分 |
+| [PySceneDetect](https://github.com/Breakthrough/PySceneDetect) | ContentDetector 计算相邻帧变化；AdaptiveDetector 将目标帧分数与周围帧均值比较，同时检查最小内容变化和最短镜头 | 多素材拆镜头、混剪候选片段 | [BSD-3-Clause](https://github.com/Breakthrough/PySceneDetect/blob/main/LICENSE)；负责边界检测，不负责语义或商品识别 |
+| [librosa](https://github.com/librosa/librosa) | onset strength → 节奏估计 → 动态规划选节拍；综合局部强度与节拍间隔一致性 | 背景音乐卡点 | [ISC](https://github.com/librosa/librosa/blob/main/LICENSE.md)；弱节奏/静音可能无有效节拍，必须显式回退 |
+| [FFmpeg](https://ffmpeg.org/ffmpeg-filters.html) | trim/atrim、setpts/asetpts、concat、xfade/acrossfade、字幕渲染、响度处理 | 最终确定性合成 | 使用部署环境既有构建；具体许可依构建组件，不把所有构建概括成同一许可 |
+
+阅读位置：FunClip `funclip/videoclipper.py` 的 `recog`、`clip`、`video_clip`；PySceneDetect `scenedetect/detectors/adaptive_detector.py` 的 `process_frame`；librosa `librosa/beat.py` 的 `__beat_tracker`、`__beat_track_dp`。这些代码已下载到本地研究目录查看，没有安装来源不明的脚本或启动重模型服务。
+
+FunClip 的关键点是可靠的时间戳映射，而不是让语言模型随意猜视频秒数。它既接收文字匹配，也接收显式时间区间，再重算片段字幕。不能把“ASR 文字剪辑”直接等同于“无对白产品素材混剪”。
+
+PySceneDetect 的自适应比值为目标变化分数除以邻域平均变化分数，另加内容阈值和最短镜头限制。这能减轻连续快速运镜带来的误切，但闪光和缓慢转场仍需结合素材调阈值。[算法实现](https://github.com/Breakthrough/PySceneDetect/blob/main/scenedetect/detectors/adaptive_detector.py)
+
+librosa 的节拍跟踪先形成起音强度曲线，估计速度，再用动态规划寻找与速度相容的强起音序列，不是简单按固定秒数平均切。低置信度时保留普通剪辑并标明未检测到稳定节拍。[算法文档](https://librosa.org/doc/0.10.2/generated/librosa.beat.beat_track.html)
+
+## 与现有系统的接入方案（尚未上线）
+
+优先组合 FunClip 的时间戳选片思路、PySceneDetect、librosa 和现有 FFmpeg；千问3.8继续负责素材语义、脚本要求和候选镜头排序。无需为了剪辑更换现有生图/视频模型。
+
+1. 预处理：现有受限下载器取得素材；ffprobe 读真实时长/FPS/音轨；以素材 hash 缓存低清代理、镜头边界、ASR 和节拍，避免反复解析。
+2. 候选分段：有对白时按 ASR 句子和说话人形成候选；无对白时按场景边界形成候选。去静音只作可选粗剪，保留前后余量，不切断语词。
+3. 语义选片：把候选 ID、真实开始/结束、抽帧与转写传给现有千问3.8，只允许模型返回候选 ID、用途和排序。服务端校验所有 ID 和区间；无素材时不能虚构成片。
+4. 卡点：分析用户选定/生成的音乐，输出真实 beat 秒数。根据最低镜头时长与素材余量，选每 2/4 拍换镜头，平衡节奏、语义连续性和目标总时长。口播优先语句边界，音乐卡点不能强行截断对白。
+5. 形成可编辑 EDL：记录素材 ID、sourceIn/sourceOut、timelineStart、speed、音量、字幕、转场。前端预览、时间轴修改和后台导出使用同一份 EDL。用整数微秒或有理数时间避免浮点累计漂移，显示时转换为帧。
+6. 合成：统一尺寸/FPS/像素格式/采样率；每段 trim 后时间归零。转场重叠计入总时长；无音轨片段补静音以保持 A/V 对齐；FFmpeg 执行显式参数数组，进程限时限并发，上传归档。
+7. 持久任务：分为解析、选片、编辑计划、渲染、转存，各步保存结果和输入版本。刷新或断线恢复同一任务，编辑后旧任务不能覆盖新版本；失败显示具体阶段。
+
+示例 EDL 合同：
+
+```json
+{
+  "version": 1,
+  "timebase": "microseconds",
+  "canvas": {"width": 1920, "height": 1080, "fps": 30},
+  "clips": [{"id":"clip-1","assetId":"asset-a","sourceIn":1000000,"sourceOut":3000000,"timelineStart":0,"speed":1,"volume":1}],
+  "music": {"assetId":"music-a","start":0,"gain":0.2},
+  "subtitles": [],
+  "transitions": []
+}
+```
+
+## 对照记录与剩余工作
+
+| 能力 | 当前项目状态 | 后续验收条件 |
+| --- | --- | --- |
+| 单视频裁剪、抽帧、音轨提取、慢放 | 现有真实 FFmpeg 功能 | 已有测试继续保持 |
+| 四类智能剪辑预设的自动成片 | 本次完成参考站与开源源码研究，未接入完整剪辑服务 | 上传不同素材后产生可编辑 EDL 与真实成片 |
+| 去静音/ASR 语义选片 | 选定开源候选，尚未部署 | 验证中文、低音量、无音轨、多人语音 |
+| 音乐卡点 | 已明确 librosa 算法与回退策略，尚未接入 | 合成脉冲音乐和真实音乐的切点误差可量化 |
+| 多素材时间轴、字幕、转场 | 仍需 EDL 编辑器和合成执行器；不把单片裁剪宣称为智能混剪 | 预览/导出逐片一致，跨转场音画同步 |
+
+48 服务器此前反馈过内存高。部署 ASR 时应先核对实际可用资源，再使用独立受限 worker；不要在每个 Web 请求内加载一份模型。此处是实施建议，本次没有启动新的常驻模型服务。
+
+
+## 实施更新
+
+以上是最初调研时点。已实现的开源分析与剪辑链路、实际验证和独立合成部署状态见 [视频合成服务实施记录](video-render-service-2026-09-17.md)。FunASR仍未完成真实权重验收，不把适配代码等同于转写已可用。

+# 视频画布任务与交互修复 · 2026-09-17
+
+承接 `23f86dfc` 的全面扫描。用户补充“浏览器刷新一下就好了”，本轮重点修复任务结果与页面状态脱节，同时处理 F02–F07 中已确认的入口问题。本记录是分支修复与本地验收，未部署 48 服务器，也没有把原 231 项清单改成全部通过。
+
+> 前半部分保留 0d17638a 阶段记录；本轮新增修复和验证见文末“后续修复”。
+
+## 修复范围
+
+| 扫描项 | 本轮改动 | 验证及边界 |
+|---|---|---|
+| F01 任务恢复 | 新增统一生成任务接口、数据库受理记录、请求 ID 去重、原子领取、心跳与结果保存；客户端提交前保存待核对请求，刷新/重开/online/focus/visibilitychange 时查询；去掉虚假进度；旧版无任务 ID 的 pending 明确提示无法恢复 | 主图像/视频生成、配置工具的图像/视频/分析、脚本再生成、批量分镜/视频接入。局部编辑按已有 taskId 恢复查询。真实数据库与浏览器验收见下文。专用图像后期、角度编辑、脚本弹窗资产生成/逐镜提示词仍有同步请求，未宣称全部入口具备同等恢复能力 |
+| F02 取消 | 排队任务通过数据库 CAS 取消；已提交供应商的任务返回明确说明，继续保存结果；删除已完成结果写入任务隐藏记录 | 数据库并发及浏览器排队取消通过；没有冒充支持上游中止 |
+| F03 模板 | 待执行模板设为 idle；参考样例标记示例；空脚本不再显示硬编码成稿 | 代码检查；未逐个模板做生产生成 |
+| F04 脚本 | 脚本入口统一 story-script；空响应/无有效镜头返回失败并保留旧稿 | 结果契约回归通过；脚本资产生成与单镜提示词处理不是此次持久队列接入范围 |
+| F05 批量 | 批量分镜和视频实际入队；按有无首帧选择兼容模式，采用模型声明的离散时长/比例/分辨率；完成任务不重复提交，失败/空节点可继续执行 | 模型参数和任务契约通过；没有新增真实付费批量请求 |
+| F06 素材弹窗 | 去掉假分页和无效图标，增加搜索、纵向滚动、自适应列、素材名称与明确数量单位 | 实际组件注入 100 个素材，第 100 项能选中、确认回传，搜索返回 1 项；使用当前 Tailwind 编译产物验收 |
+| F07 次级控件 | 文本及音频生视频提示词翻译接真实接口并预览后应用；旧脚本编辑聚焦；资源替换接上传；通知显示真实任务；模板筛选使用配置数据；退出接现有登出流程；未实现按钮明确禁用 | 代码与类型检查。未实际退出生产账户，未声称所有停用高级能力已实现 |
+
+任务表复用既有 `0091_add_canvas_capability_tasks.sql`，没有新增数据库迁移。上线前须核对该既有迁移已应用。
+
+## 任务一致性
+
+- 同一请求 ID 重试不会重复执行；同一节点已有活动任务时复用现有任务。
+- 同画布任务串行领取，多执行者通过 PostgreSQL 事务锁与状态更新竞争。
+- 刷新前画布尚未保存的已受理节点，可从任务快照补回；不会从旧任务复活已保存删除的节点。
+- 多图结果使用任务 ID 与序号组成稳定结果节点 ID，轮询不重复追加，重新生成不误用上次附图。
+- 旧请求不能覆盖新请求；画布保存落后于新任务时，根据任务时间和保存版本恢复最新结果。
+- 连线仅首次恢复时补齐，后续轮询不反复恢复用户已经删除的连线。
+- 执行进程心跳超过 120 秒未更新，任务标记待核实；不自动重新提交付费请求。若原执行稍后确实返回，仍允许保存真实结果。
+- 浏览器离开与服务端执行进程重启是不同情况：本轮解决前者的主要入口；进程中断后尚未实现供应商任务 ID 的自动续查。
+
+## 验证记录
+
+1. **真实本地 PostgreSQL**：`scripts/qa/video-canvas-task-db.cjs` 建立隔离测试库，加载实际任务表迁移和实际 store。10 次并发相同提交只创建 1 条记录；10 次并发领取仅 1 次成功；跨用户隔离、排队取消、执行中不可取消、串行队列、结果保存、结果隐藏、过期不重投、晚到结果保存全部通过。这是并发数据库调用测试，不是 10 个操作系统进程实测。
+2. **真实浏览器任务恢复**：验收页使用实际 React Hook、实际任务 route/worker/store 与本地 PostgreSQL；鉴权使用固定测试用户，NextResponse/after 使用本地适配器，模型返回使用 12 秒测试桩。提交图片后立即刷新，最终出现 2 个结果且只 1 条任务；视频执行时关闭页面，再打开能恢复结果；后续分析排队任务成功取消；移除附图后刷新不复活。画布快照保存使用本地验收服务器，不是生产画布接口。
+3. **实际素材组件**：100 项列表可定位选择最后一项，确认回传 `测试素材 100`；搜索同名只剩 1 项且保留选中状态；已有第 100 项再连续点选第 1–10 项，最终只选中 10 项，第 10 项（第 11 次选择）被正确拦截。验收期间先发现旧测试样式缓存，重新编译当前源码样式后验证通过。
+4. **自动化**：最终 helpers/route 回归 437 项通过，无跳过，包含本次新增 13 项任务/批量参数测试和既有真实 FFmpeg 检查。不是 437 个生产端到端测试。
+5. **静态检查**：TypeScript 无错误；`git diff --check` 通过。新增服务端模块与旧接口共享执行逻辑，图像计费仍走原有计费模块。
+
+没有进行新的付费模型测试，没有重新宣称参考站像素级一致，没有覆盖操作系统休眠、真实断网、多标签冲突、生产 Next.js 进程重启或生产部署后的回归。原扫描中 79 项缺失/停用能力依然需要单独实现与验证，详见原验证矩阵。
+
+## 复现
+
+```sh
+# FFmpeg / ffprobe 必须在 PATH 中，避免媒体测试跳过
+pnpm exec playwright test --config=playwright.helpers.config.ts
+pnpm exec tsc --noEmit --incremental false
+# 隔离数据库测试依赖仅装入忽略的 .qa 目录，不改项目依赖
+npm install --prefix .qa/video-task-db --no-save embedded-postgres
+node scripts/qa/video-canvas-task-db.cjs
+```
+
+浏览器验收脚手架位于忽略目录 `.qa/video-durable` 和 `.qa/video-repair`；上述记录保留测试方法和模拟边界，不能代替后续部署验收。
+
+## 后续修复：图片后期与脚本子任务（承接 0d17638a）
+
+本轮把角度编辑（自定义参数及预设）、高清、扩图、抠图、宫格批量放大，以及脚本弹窗的资产生成、单镜/全部提示词合成接入已有持久队列。结果节点在提交时创建，完成后由任务查询更新；脚本任务另外按资产 ID、镜头 ID 回填对应字段。生成期间的修改或删除会保留，新结果继续留在独立节点，并显示冲突说明。脚本弹窗重新打开后显示服务器任务的处理中/失败状态。
+
+高清接口的 AOS 分支可能先返回 HTTP 202 和 taskId。之前视频画布同步调用只寻找 original_url，导致将“已受理”误当失败。本轮先保存上游 taskId，再调用原有 GET 查询；查询中断或达到等待上限时标为“待核实”，保留上游标识，不重新 POST。当前仍不自动恢复服务端进程重启后的上游查询，需后续补全；浏览器刷新不影响在运行的服务端查询。
+
+四个原 API 的执行实现抽取到 `lib/canvas/operations/`，原 URL 的入口继续通过 auth 验证身份；队列使用已校验的任务所有者调用共享执行函数。逐文件比较确认模型、存储、计费执行逻辑与抽取前保持一致。另修正上轮清理共享生图模块时遗漏的 `getCanvasImageTaskForUser` 导入，本轮完整类型检查通过。
+
+本轮验证：
+
+- helpers/route 回归 **447 项通过，无跳过**，其中任务专项 23 项；新增后期参数校验、202 续查只提交一次、断网/502/等待上限待核实、角度响应、空结果拒绝、脚本稳定 ID 回填与修改冲突保护。
+- 真实隔离 PostgreSQL：原并发/权限/取消检查通过；新增上游任务标识写入、待核实时保留标识、不自动重投检查通过。
+- 本地浏览器：实际 Hook/API/worker/store + PostgreSQL；鉴权、模型和后期服务使用测试桩。高清提交后刷新恢复；脚本资产提交后刷新自动回填；提示词提交后刷新自动回填 imagePrompt/motionPrompt，原对白保留；生成中修改资产的冲突保护单独检查。画布保存仍使用本地验收接口，不是生产画布 API。
+- TypeScript 与 diff 空白检查通过；没有新增付费模型调用，没有部署 48 服务器。
+
+仍需继续的项目：视频解析故事入口尚有同步请求，后台进程中断后的上游续查、多标签同时编辑、生产部署回归，以及原矩阵中的高级功能缺口。本轮不据此宣称 231 项全部完成。
+
+## 后续修复：视频故事与上游任务续查（承接 86b66172）
+
+本节更新前面仍标为未完成的“视频解析故事”和“AOS 高清已有任务编号续查”。这两项已完成分支修复与下述本地验证，其他范围不因此自动视为已修复。
+
+### 视频解析故事
+
+- 工具栏“解析故事”在提交时创建故事节点，进入实际持久任务队列；刷新、重新打开画布后通过任务状态恢复结果。故事节点重新运行也走视频解析，修正了原先落入通用脚本生成分支的问题。
+- 解析失败或模型返回空镜头时显示错误并保留旧稿，新节点显示 0 镜。移除前后端自动填入的开场剧情、运镜、灯光、音乐等占位内容；缺失字段显示空值。
+- 前后端共用镜头规范化逻辑，保留时间 0，不再截断成最多 8 镜；目前上限 120 镜。双击提交由本地提交锁和服务端同节点任务去重保护。
+
+### 高清续查
+
+- AOS 受理后先持久化 taskId、操作类型与源图，再查询结果。执行进程中断后，只恢复服务器已保存且与原请求匹配的高清编号；恢复分支只 GET 原任务，不重新 POST。
+- 下一次画布任务查询发现心跳过期后标记 interrupted，再按 30 秒起、最高 5 分钟的间隔接管续查；限任务创建后 24 小时、总领取次数少于 20 次。不依赖后台永久调度器，服务重启后需要画布查询触发恢复。
+- 增加领取次数校验：旧执行者的心跳、结果、检查点与失败不能覆盖已被新执行者接管的任务。恢复窗口内对同一节点重复点击运行会复用原任务。
+- AOS 明确负数失败状态立即终止查询，修正被吞掉后长期显示 processing 的问题；每次网络查询有超时，整个短轮询按实际经过时间计时。
+- 仍未给没有持久化上游编号的其他供应商任务添加自动续查；视频模型及 VIP98K 同步调用在进程中断后的恢复不能据此视为完成。没有任务编号的请求不会自动重投。
+
+### 本轮验证
+
+- helpers/route **454 项通过，无跳过**，其中任务专项 30 项；包含既有真实 FFmpeg 验证。新增检查编号匹配、恢复时限/间隔、GET-only 恢复、执行权失效、终态失败、AOS 短轮询上限、完整镜头及空结果拒绝。
+- 真实隔离 PostgreSQL：10 个并发调用争抢续查只有 1 个成功；旧领取次数的结果/错误/检查点不能覆盖新领取；重复提交恢复中的节点不会新增任务。
+- **独立进程中断与重启**：实际 worker/store + PostgreSQL，供应商使用本地桩。首次进程在受理、保存编号并开始 GET 后强制退出，第二个独立进程从库恢复并完成。调用记录严格为 `POST → GET → GET`，上游编号一致。这不是生产 Next.js 部署重启测试。
+- **浏览器刷新**：实际故事节点组件、Hook、route、worker、store + PostgreSQL；鉴权/供应商/Next after 使用本地适配。故事任务处理中刷新后恢复为 1 个真实桩镜头；另一个空镜头响应变为失败，刷新后仍显示 0 镜与明确错误。画布快照保存仍为本地验收接口。
+- TypeScript 无错误、diff 空白检查通过。没有新增付费模型调用，没有部署 48 服务器。
+
+后续仍需完成：其他供应商执行中断恢复、多标签编辑冲突、生产部署回归，以及原矩阵列出的高级功能缺口。本次未声称参考站 231 项全部完成或像素级一致。
+
+## 后续修复：五类视频续查、多页面保存与 3D 加载（承接 69dcf9b7）
+
+本节更新前面仍列为待办的五类视频供应商续查、多页面冲突和部分导演台能力。以下均为分支修复与本地验收；没有部署 48 服务器，没有新增付费生成，也没有声称参考站 231 项全部完成。
+
+### 视频提交与恢复
+
+- 阿里云、VIP98K external task、火山、AtlasCloud、Agnes 五类异步视频适配器接入同一任务生命周期。上游受理后先保存 taskId、原模型和服务商身份，再查询；恢复只 GET 原编号，不重复准备参考素材或 POST 生视频。
+- 恢复沿用既有 24 小时窗口、最多 20 次领取、30 秒至 5 分钟退避及执行权校验。由画布任务查询触发，不是脱离画布的永久后台调度器。
+- 模型或服务线路发生变化时停止自动查询并保留原编号。未取得编号的网络中断显示待核实，不自动重新提交；VIP98K/火山的持久任务路径禁用不确定 POST 的自动重试。明确的图片超限拒绝仍允许火山压缩后重试。
+- 明确失败/取消结束任务；AtlasCloud 的终态错误即使含有 network 字样也不会误当临时网络故障继续等待。没有上游编号的旧任务不能凭空恢复。
+- 去掉领取恢复任务时旧的 240 条扫描截断，按恢复窗口和领取次数筛选，避免陈旧记录挡住可恢复任务。
+
+### 多页面保存与草稿
+
+- 遇到保存版本冲突，读取最新服务器内容，对基线、本页与服务器三个版本按节点/连线稳定 ID 和字段合并。不同位置的修改自动保留，同字段、删除与编辑、相互冲突的顺序修改必须显式选择。
+- 页面展示冲突位置，可选择冲突处保留本页或服务器版；无冲突的修改继续保留。支持下载当前 JSON 草稿，不再让用户只能刷新丢掉一版修改。
+- 浏览器 sessionStorage 按画布保存当前标签页的未保存草稿，隐藏、离开和定时保存前保留；重开当前标签页时与服务器版本合并。修正初始化时旧快照覆盖刚恢复草稿的问题。
+- 移除节点序列化时每次重造的 createdAt/updatedAt，避免产生虚假冲突；服务器版本时间至少递增 1 毫秒。
+- 远端连续保存导致超过 3 次自动合并重试时，暂停并保留草稿，用户仍可手动重试，不会进入永久阻塞。当前只在保存冲突时拉取其他页面版本，没有新增实时多人协同；sessionStorage 不是跨设备备份，存储满时仍需使用草稿下载。
+
+### 3D 导演台逐项记录
+
+| 原矩阵 ID | 当前实现与修复 | 验收及剩余边界 |
+|---|---|---|
+| 08-01、08-15 | GLB 30 秒超时、404/解析失败提示、空几何拒绝、重试加载；WebGL 上下文丢失后可重建场景；异常中止视频导出 | 实际浏览器：404→重试显示橙色方块；35 秒响应在 30 秒提示超时，晚到结果不冒充成功；空模型提示无有效几何；模拟 GPU 丢失→重试恢复原对象。未覆盖所有浏览器/显卡 |
+| 08-10 | 八个人偶体型比例预设 | 实际浏览器选择幼童、重开保存；回归验证持久化。这是简化人偶比例，不等同参考站八种精细角色资产 |
+| 08-14 | 复制对象与 3×3 群众阵列，限制总数 200 | 实际浏览器显示 9 个人偶；回归验证数量、间距、上限。未新增自定义行列阵列编辑器 |
+| 08-17、08-18 | 上传 2:1 全景图、20 MiB 上限、20 条背景历史、默认背景、失败/20 秒超时提示及重试 | 实际 TextureLoader 浏览器渲染本地全景测试图、404 错误与切回默认背景；上传调用现有服务，未做生产对象存储上传验收 |
+| 09-02、09-14 | 各机位保存独立相机轨迹，切换不串轨 | 浏览器：机位 1 两帧→新机位零帧→机位 1 恢复两帧；序列化回归通过。尚不是对象、相机、灯光同时运行的完整多轨系统 |
+| 09-04、09-05 | yaw/pitch 旋转、持续注视所选对象；预览、截图、真实录制和发送的运镜描述共用相机解析 | 浏览器移动对象后注视坐标跟随，手动旋转会退出跟随；方向/距离及解析一致性回归通过。未实现相机位置跟随对象平移或物体动画轨 |
+| 09-13 | 编辑机位时自动记录当前时间关键帧 | 浏览器启用后旋转相机更新当前帧；预览播放不自动写帧 |
+| 09-19 | 整条轨迹右移 1 米、轨迹与注视方向一起转 90° | 浏览器检查变换后的首帧坐标；回归验证距离不变。不是自由变换轴或铅笔/钢笔路径编辑器 |
+| 09-24 | MP4 不支持时回退 WebM VP9/VP8/默认编码，文件名与内容类型一致 | 录制测试覆盖 MP4 与 WebM 回退、切后台/取消/渲染失败清理；本轮未新增真实生产视频上传 |
+
+### 最终本地验证
+
+1. helpers/route **468 项通过，无跳过**，包括真实 FFmpeg 检查。新增模型恢复、合并冲突、独立轨道/跟随/体型/轨迹等回归；不是 468 个生产端到端测试。
+2. `scripts/qa/video-canvas-provider-recovery.cjs` 调用实际模型选择与五类供应商适配器，使用合成目录、凭证及 fetch 响应。逐一验证受理后先存编号、查询中断、GET-only 续查、原服务商身份、明确终态失败只查一次、提交网络中断只 POST 一次。脚本禁止访问测试域名以外的网络，没有付费生成。
+3. `scripts/qa/video-canvas-task-db.cjs` 的真实隔离 PostgreSQL 检查通过，新增视频编号持久化、重复节点去重、10 个并发调用仅一个接管；保留原高清独立进程中断恢复测试。视频本轮没有另做生产进程重启测试。
+4. 两个真实浏览器标签页使用实际持久化 Hook 和冲突组件：不同节点修改自动合并，同节点冲突可选择且保留另一节点修改；恢复预置的 sessionStorage 草稿后可保存。画布 CAS 接口为本地验收服务器，没有写生产项目。
+5. 实际导演台组件的 WebGL、独立机位、跟随、自动帧、群众阵列、全景和加载异常验收见上表。浏览器脚手架位于忽略目录 `.qa/video-concurrency`。
+6. TypeScript 无错误，Git diff 空白检查通过。复现供应商检查：`node scripts/qa/video-canvas-provider-recovery.cjs`；其余测试命令同前文。
+
+### 仍未完成的范围
+
+原矩阵是历史扫描基线，本节是增量结果，不能据此将原 79 项缺失全部改为已完成。仍缺：TTS/音乐/音色接口，多画布/故事板/Agent 与跨项目资产，部分专用视频后期和智能剪辑，精细角色/手工关节、AI 识图重建、AI 全景、对象多轨、时间轴单位缩放、自由绘制轨迹，以及参考站逐状态像素对照与上线验收。现有服务尚无通用 TTS/音乐实现，不能用仅有入口或普通模型目录代替这些能力。未接通入口继续明确标示状态。

+# 视频画布全面验证扫描 · 2026-09-17
+
+后续修复记录：[任务与交互修复](video-canvas-task-repairs-2026-09-17.md)。以下内容保留扫描时的基线，不代表修复后的现状；也未将未验收项批量改为通过。
+
+结论：**仍有未验证功能，也有已确认但尚未修复的功能缺口，不能判定全面验收通过。** 本轮以 `f10e6b7c` 为代码起点，核对原 10 组、231 项对照清单，追踪活动页面的调用、请求和保存流程，补跑相关回归与实际组件浏览器验证。没有重新提交付费模型任务，没有重新实测参考网站，也没有部署 48 服务器。
+
+## 证据范围
+
+| 分类 | 项数 | 含义 |
+|---|---:|---|
+| 待专项验证 | 56 | 主要有代码/对照记录，缺少对应的专项验收证据 |
+| 有部分证据，未完整验收 | 80 | 有代码检查、契约回归、本地组件或历史实测之一；不等于全链路通过 |
+| 仍有问题 | 16 | 关联下方 F01–F07 的具体问题；多个条目可属于同一问题 |
+| 缺失或停用 | 79 | 没有等价实现，或已明确禁用；不是单纯漏测 |
+| 合计 | 231 | 分类为保守的验证工作清单，**不是产品完成率** |
+
+完整逐项清单：[验证矩阵](video-canvas-validation-matrix-2026-09-17.md)，机器可读数据：[验证 JSON](video-canvas-validation-scan-2026-09-17.json)。原对照文件是旧基线，本次没有把旧状态全部改成“已完成”。
+
+## 本轮确认的未完成项
+
+| 编号 | 级别 | 触发与结果 | 证据位置 | 后续验收要求 |
+|---|---|---|---|---|
+| F01 | P1 | 生成中刷新/重开：保存的 pending 节点没有重新查询视频任务；本地定时器仍将进度推到 96%。局部编辑有 taskId，但轮询仅从提交入口启动，加载时未恢复 | `LiblibVideoCanvasReplica.tsx`：加载约 4922、定时器 5052、局部编辑 7214/7471；`services/canvas/index.ts` 的 generateVideo 为一次 HTTP 请求 | 服务端持久任务 ID、查询/续订、过期状态；真实刷新、断网、切后台、重开后恢复成功/失败，且不重复扣费。仅切后台是否必然失败本轮没有实测结论 |
+| F02 | P1 | “取消生成”→“确定”只关闭弹窗；请求仍继续。弹窗却写“停止将不退还算力” | 活动根组件约 10807：onCancel/onConfirm 都只 setCancelGenerationConfirmNodeId(null) | 明确上游能否取消；不能取消时真实告知。排队取消、执行中取消、取消后晚到结果分别验证 |
+| F03 | P1 | 快捷模板仍注入示例素材；角色三视图、首帧模板直接设 generated:true，未执行真实生成 | createStarterWorkflow 约 4588；getConfiguredReferenceAsset 约 3490 | 示例清楚标识；未运行节点不标生成完成，历史/导出不混淆样例与用户结果 |
+| F04 | P1 | 脚本弹窗“重新生成”调用 runNode；连入图片/视频后会选择 image-to-prompt/agent-plan。工具栏另一路却使用 story-script；此外 success:true 但空数据仍可能标完成 | 弹窗 onRun 约 11350；runNode 约 9740；runStoryScriptToolbarAction 约 8352 | 相同脚本在两入口生成应走同一功能契约；空响应、缺镜头字段保留旧稿并报告失败 |
+| F05 | P1 | “批量生视频”目前只创建生成器；没有首帧也取首帧模型；时长只限 2–15 秒，不遵守模型离散时长 | runStoryScriptToolbarAction 约 8623–8660 | 无图选兼容文生模式或拦截；批量真正执行、规格约束、部分失败续跑、刷新恢复 |
+| F06 | P1 | 素材选择弹窗仍保留无处理函数的上一页/下一页、“15条/页”和跳页外观；一次渲染所有素材，容器没有明确的纵向滚动，超一屏可达性待验。卡片垃圾桶/预览是 span | HistoryAssetPickerModal 约 23016–23190 | 去掉假分页或接真实分页；超过 15/100 条、最后一项可选、预览/删除行为和选择上限分别验收 |
+| F07 | P2 | 仍有仅提示“待接入”或无行为的次级控件：文本翻译、音频生视频高级设置/展开、旧脚本编辑、我的工具箱、通知分类、发布和账户退出等 | TextTargetModuleComposer、AudioToVideoComposerPanel、PresetScriptCanvasNode、WorkflowPanel、NotificationsPopover、PublishModal、AccountPopover | 与主入口逐一比对；接通或明确禁用，不能用主入口成功覆盖旧入口 |
+
+上述判断来自代码调用链；没有把它们描述为全部浏览器复现。F01/F02 是优先项，关系到用户看到的长时间处理中和重复提交风险。
+
+## 本轮修复并补验的三个小问题
+
+1. **多角度方向箭头**：鱼眼/倾斜选中后，箭头修改数值仍保留特殊预设，提交会走特殊提示词路径。四个方向按钮现与滑块一致切到“自定义”。实际组件浏览器复现修复前 `preset=鱼眼视角,horizontalAngle=10`，修复后为 `preset=自定义,horizontalAngle=10`；本轮没有请求供应商生成图片。
+2. **资产管理收起列表**：原先只转动箭头，节点仍显示。现在收起真正隐藏节点行，展开恢复，文案改成“节点列表”，不冒充全画布分组。浏览器已验证消失和恢复。
+3. **画布/素材筛选串状态**：原先同一 filter 同时用于“脚本/导演台”和“图片/视频/音频”，切页可留下素材下拉框没有的选项。现在两套筛选各自保持；浏览器验证画布选“脚本”→素材默认为“全部”→素材选“视频”→返回画布仍为“脚本”。
+
+另补验脚本合成的失败分支：本地静态服务器对真实分析请求返回 501，页面显示“工作流分析失败”，保留两行脚本和已修改对白，提示词完成数仍为 0/2。该结果只证明组件对这类失败的处理，不代表生产分析服务成功。
+
+## 自动化检查
+
+- 视频画布专项六组：**56 项通过，无跳过**；包括真实本地 FFmpeg 视频截帧、2/3/5 倍慢放及音轨验证。
+- 扩展 helpers 全量首轮：423 项中 421 通过，2 项模型目录用例失败。追溯到 2026-09-07 的 `e49b0707e`：目录已要求明确的多图输入契约，旧用例只有 image-to-image 标签。既有 `vip98k-reference-routing` 测试也要求不能从宽泛标签推断多图能力。
+- 补齐旧用例的数组输入 schema，并新增“只有标签/单图字符串 schema 必须拒绝”的反例，**未放宽生产筛选规则**。模型分类与参考路由专项 52 项通过。
+- 最终全量：**424 项通过，无失败、无跳过**。这 424 项是当前 `playwright.helpers.config.ts` 中的 helper/route 契约回归，**不是 424 个完整页面端到端测试，也不是全部供应商实测**。
+- TypeScript 检查通过（最终提交前重跑）。
+
+复现：FFmpeg/ffprobe 加入 PATH 后执行 `pnpm exec playwright test --config=playwright.helpers.config.ts`。若未安装这两个程序，媒体测试会跳过，不能沿用“真实媒体通过”的结论。
+
+## 活动入口扫描方式
+
+`node scripts/audit/video-canvas-controls.cjs output.json` 用 TypeScript AST 从实际入口 `LiblibVideoCanvasReplica` 追踪本文件标识符引用，记录缺少直接事件/仅提示类控件的候选。本轮 400 个可达声明、41 个未引用函数、53 条控件候选。候选列表见 [控件扫描 JSON](video-canvas-control-scan-2026-09-17.json)。
+
+这是保守静态扫描，不是运行时覆盖率：组合组件可用其他回调，submit 按钮可由 form 处理，恒为 false 的分支仍可能被扫描到。因此 **53 条候选不等于 53 个故障**。例如 VideoArchiveButton/工作流组合组件有真实回调；运镜搜索走 form submit；ZoomDock 的 compact 分支未在当前调用启用。旧 DirectorConsole3DDialog 等 41 个未引用函数未用于证明当前活动导演台故障；实际 3D 在 `components/canvas/director/` 中复核并由对应回归覆盖。
+
+## 下一轮必须补齐的验证
+
+- **任务生命周期**：刷新、断网重连、浏览器后台、退出重开、重复点击、批量中的取消/删除、多标签同时编辑；现有保存队列单测不能代替这些场景。
+- **生成与脚本**：逐模型/模式规格、真实多张返回、批量混合成败、脚本单镜/全部合成成功、资产生成上传、脚本到图片再到视频完整闭环。历史某条供应商线路成功不等于今天所有线路通过。
+- **素材与后期**：超过一屏的素材、跨域/过期 URL、ZIP 部分失败、音频上传格式与时长边界、网页播放器当前时间截帧、无音轨文件、长视频资源占用。
+- **3D 导演台**：全部 12 姿势/12 机位逐项视觉检查，4 类轨迹浏览器端运行；弱网/损坏/超大 GLB，WebGL 上下文丢失，切后台中断导出，多浏览器编码格式与生产上传。既有单测和历史一条 MP4 导出不足以覆盖这些情况。
+- **布局与一致性**：不同分辨率、缩放、空态/加载/失败/完成逐状态像素比对；本轮没有新增与参考站像素一致的结论。
+- **尚缺实现**：TTS/音乐/音色、智能剪辑、多画布/故事板/Agent、跨项目资产、专用后期、3D 多轨/自动帧/跟随/自由路径等，需先实现再验收。
+
+本轮范围止于扫描、三处明确界面修复及回归记录。F01–F07 未因本次扫描自动视作修复；线上版本也不会因分支推送自动更新。

+只读检查：shujuku3，AMD EPYC 7B12，64物理核/128线程，125GiB内存，可用约79GiB，根盘空余约151GiB（检查时点）。四张Tesla P40，三张已加载千问模型。现有 `qwen3.8-27b-q4-32k` 三个实例在18230/18231/18233，健康接口均成功；`/props` 明确 vision/video/audio 均为false，只能复用文字能力。
+
+部署：专用 video-render 用户和 systemd 服务，FFmpeg 6.1.1，已有 Noto CJK 字体。CPUQuota=400%，MemoryHigh=6G，MemoryMax=8G，并发1，监听127.0.0.1:18340。文字助手指向18231，普通合成不调用模型；此轮没有新增模型推理测试或改变现有千问服务配置。
+
+48 主机通过专用 SSH 隧道访问同一回环端口。新隧道密钥仅允许指定回环监听端口，固定主机公钥，服务另有随机 Bearer 认证。客户端凭据保存在 `/etc/video-render-client.env`，没有提交 Git。
+
+## 已验证
+
+- 真实 PySceneDetect 识别三个色块镜头；RMS识别两段有声区间；librosa识别22个节拍。
+- 真实 FFmpeg：直接拼接4秒、叠化后3.5秒，含无音轨素材、2倍速、配乐和中文字幕。
+- 独立 HTTP 服务真实测试：无凭据401、同ID重复提交幂等、不同参数409、强制杀进程后重启恢复、完成后重启仍可下载。
+- 48主机适配器→加密隧道→算力服务→读取成片→现有对象存储归档：720p横屏及1080p竖屏成功。竖屏额外覆盖三片段、非整秒边界、不同速度和0.25秒叠化。
+- 真实 React 组件操作：添加素材、生成方案、转写未就绪禁用、分割、变速、转场、排序、导出参数、关闭重开恢复、EDL下载。尚需主项目发布后的完整页面验证。
+- helpers 482项通过，1项跳过；TypeScript通过。真实PostgreSQL队列回归通过。
+
+## 智能剪辑实现范围
+
+四种模式、最多三版广告排序、语句/镜头候选、可选千问3.8视觉选片、节拍切镜、去静音、可编辑时间轴和字幕、方案/SRT下载、成片回到画布。模型语义请求状态不明确时禁止重复调用。广告多版本目前是候选排序轮换，不能宣称独立创意脚本生成。
+
+FunASR适配与安装脚本已实现，未装权重、未做真实ASR验收，界面禁用自动转写并支持导入SRT。当前本地千问接口不能替代视觉选片，视觉分析继续使用主项目已有模型配置。
+
+部署边界：独立合成服务已启动且两机链路实测通过；主项目正式应用的切换状态将在发布验证后追加。此前音频/导演台等开发分支改动不能凭本记录视为已经上线。

+
+从项目根目录运行 `bash services/smart-edit/setup.sh`。准备 Python 3.11、FFmpeg/ffprobe（包含 libx264 与 subtitles/libass）、中文字体（Linux 推荐 Noto Sans CJK）。基础分析依赖按版本固定，虚拟环境独立。
+
+应用环境配置：
+
+- `SMART_EDIT_PYTHON=/绝对路径/.venv-smart-edit/bin/python`
+- `SMART_EDIT_CACHE_DIR=/有足够磁盘空间的私有目录/smart-edit-cache`（缺省 `.cache/smart-edit`）
+- 运行目录保持项目根目录；Next standalone 打包已包含 analyze.py，Python 与 FFmpeg 单独安装。
+
+语音识别选装：执行 `bash services/smart-edit/setup.sh --with-asr`，会安装 FunASR/PyTorch 并从 ModelScope 下载官方 Paraformer、FSMN-VAD、CT-Transformer 三个模型。把脚本输出的 `SMART_EDIT_ASR_MODEL`、`SMART_EDIT_VAD_MODEL`、`SMART_EDIT_PUNC_MODEL` 路径写入应用环境。模型代码禁止 trust_remote_code，用户请求不能选择任意模型文件。模型权重下载可能较大，应在维护期间完成；请求阶段仅读取已经配置好的本地模型。
+
+诊断：`$SMART_EDIT_PYTHON services/smart-edit/analyze.py --check`。API `/api/canvas/smart-edit/capabilities` 仅对登录用户返回可用功能与模型列表，不返回密钥或本地路径。ASR 未准备好时页面关闭自动转写选项，仍可导入 SRT 和进行画面混剪。

+资源：整个智能剪辑作业通过 PostgreSQL advisory lock 限制为同一数据库下同时一个重处理任务，租约心跳沿用画布任务队列。Python/FFmpeg 限制线程数，单素材 ≤180 秒、≤125 MiB、至多6份，总素材≤10分钟，成片≤90秒、≤12片段；分析缓存按用户隔离，内容 hash 校验，7天过期、4GiB上限。低清代理仅用于分析，成片使用原素材。数据库锁繁忙时任务保存为可恢复状态，页面轮询或返回画布会继续运行。
+
+算法：PySceneDetect 检测镜头，librosa 检测节拍，FunASR 返回语句时间戳（采用 FunClip 的时间戳剪辑思路）。去静音为独立实现的 RMS 阈值算法，参考 Auto-Editor 的粗剪与余量机制；没有复制 Auto-Editor 或 FunClip 源码，也不依赖它们的 UI。来源与许可证记录在项目 docs/video-canvas-smart-edit-research-2026-09-17.md。PySceneDetect 为 BSD-3-Clause，librosa 为 ISC，FunASR 源码和各权重许可应按所安装版本一并保留。
+
+智能选片直接复用项目内官方千问3.8视觉模型；关闭智能选片后所有镜头/节拍/剪辑流程均为本地运算。供应商受理状态不明的语义请求不会自动重发。素材文本和字幕仅为待分析数据，模型只允许返回实际候选ID，不能生成任意时间区间、文件路径或命令。
+
+预览使用同一 EDL 的时间、裁剪、速度、音量和叠化参数；浏览器流式预览受网络和解码影响。最终导出由 FFmpeg 确定性合成。音乐文件不足时末尾补静音，不默认循环；背景音量由用户调整。字幕样式与浏览器字体可能有差异。广告多版本目前对候选排序作轮换，素材不足时明确提示，不宣称独立生成多个创意脚本。
+
+
+远程合成：设置 `SMART_EDIT_RENDER_URL` 与 `SMART_EDIT_RENDER_TOKEN` 后，render操作进入独立API，不占用本地主处理锁。独立服务部署见 `../video-render/README.md`，其千问仅提供可选文字能力。分析操作仍使用本机Python/代理文件。

+# 独立视频合成服务
+
+只承接已确认的 EDL 合成。主项目保留用户鉴权、项目、分析选片、时间轴与最终对象存储归档；算力服务器下载原素材、校验内容 hash，用 FFmpeg 处理剪裁、速度、音量、转场、字幕和配乐。没有把完整主项目、数据库密码或云模型密钥复制到算力服务器。
+
+## 运行
+
+项目根目录执行 `node services/video-render/build.cjs`，生成不依赖主项目 node_modules 的 `dist/server.cjs`（Node 22，Zod 随包打包）。机器需要 FFmpeg/ffprobe、libx264、libass、中文字体。发布包放 `/opt/video-render/releases/<hash>/server.cjs`，`current` 指向当前版本。参见 `video-render.service`：专用低权限用户、单 worker、4 核 CPU 配额、6 GiB 内存软限制 / 8 GiB 硬限制。当前使用 CPU，不占用千问显卡。
+
+`/etc/video-render.env` 权限 600，环境变量：
+
+- `RENDER_API_TOKEN`：至少 32 字符随机凭据，不能提交 Git。
+- `RENDER_HOST=127.0.0.1`、`RENDER_PORT=18340`。
+- `RENDER_DATA_DIR=/var/lib/video-render`。
+- `SMART_EDIT_CACHE_DIR=/var/lib/video-render/cache`。
+- 可选 `RENDER_QWEN_URL=http://127.0.0.1:18231/v1`、`RENDER_QWEN_MODEL=qwen3.8-27b-q4-32k`。
+
+主项目配置 `SMART_EDIT_RENDER_URL=http://127.0.0.1:18340` 和同值 `SMART_EDIT_RENDER_TOKEN`。只要配置远程服务，合成请求走远程；远程连接失败不会悄悄回退到主机 FFmpeg。已有远程任务绑定原服务地址，不能在恢复时切换到另一台重复提交。
+
+两台服务器通过专用 SSH 反向隧道连接，参见 `video-render-tunnel.service`。48 上专用隧道用户只允许监听 `127.0.0.1:18340`，禁用命令、PTY、代理转发，主机公钥预先核对并固定；私钥仅留算力服务器，不使用或复制管理员私钥。合成 API 仍要求 Bearer 凭据。容器部署时 localhost 含义不同，必须显式配置宿主机访问方式。
+
+## 接口
+
+所有接口要求 `Authorization: Bearer <token>`，不接受浏览器直接访问。
+
+- `GET /health`：队列数量、活动任务数、合成方式、文字助手是否配置。
+- `POST /v1/renders`：`{id, tenant, plan}`；id 与 tenant 均为 SHA-256 十六进制标识，plan 使用 `lib/video-canvas/smart-edit/contract.ts`。
+- `GET /v1/renders/:id`：`queued/running/succeeded/failed`、阶段、重试次数、结果尺寸及时长。
+- `GET /v1/renders/:id/video`、`/subtitles`：鉴权下载产物，由主项目归档。
+- `POST /v1/assist`：可选 `{instruction, context}` 文本辅助，返回建议文字；不自动改变剪辑方案、不执行生成的代码、不支持图片视频输入。并发 1，90 秒超时，不自动重试。普通合成不会调用千问。
+
+任务 ID 由主项目持久任务号导出：重复 POST 返回同一记录，参数改变返回 409。写盘采用临时文件、fsync、rename 后再响应。单服务进程拥有此数据目录，不能启动多个副本共用目录。服务重启后运行中任务最多恢复两次；完成记录重启后仍可下载。主项目轮询超时保存编号继续查询，不受浏览器页面生命周期限制。
+
+上限：请求 1 MiB，至多 30 个等待/运行任务，至多 200 个保留任务；完成/失败记录和产物保留 7 天，小时清理；原素材缓存按用户隔离，4 GiB / 7 天清理；素材 ≤125 MiB/份、≤180秒/份、≤6份且总长≤10分钟，成片≤90秒/12片段。磁盘可用不足10GiB拒绝重处理。外部素材禁止内网地址，DNS验证后绑定地址下载，每次重定向重新验证；FFmpeg禁用网络输入协议。
+
+## 验证
+
+`PATH=<ffmpeg目录>:$PATH node scripts/qa/video-canvas-smart-edit.cjs` 生成合成素材并验证 FFmpeg。设置 `SMART_EDIT_PYTHON` 可同时验证真实 PySceneDetect、RMS、librosa。
+
+随后 `node services/video-render/build.cjs && PATH=<ffmpeg目录>:$PATH node scripts/qa/video-render-service.cjs` 验证真实 HTTP、鉴权、FFmpeg、进程强制中断/恢复、幂等、冲突拒绝和完成记录重启保留。用合成色块/正弦音，不调用付费模型。
+
+依赖许可：Zod MIT；FFmpeg 许可取决于本机编译选项，Ubuntu libx264 构建含 GPL 组件。服务只运行本机已安装 FFmpeg，不把二进制混入仓库。代码与发布状态记录在 `docs/video-render-service-2026-09-17.md`。
