没有形成持久报价；审批记录主要绑定调用参数、预览和模型名，实际提交时重新解析目录与计费。[E14] + +当前 run 总预算能限制初次准入，因此不应描述为“无预算保护”。缺口在于：等待批准期间目录/价格变化可能在总预算范围内改变最终费用；逻辑模型按渠道计价时，备用线路换价又只检查账户余额和账单，未承接初次准入的 run 剩余预算。[E15] + +后者的具体条件是：逻辑模型按渠道计价、原线路明确未接单、备用线路更贵、账户余额充足。静态代码确认约束未贯通，未执行换价或观测实际超预算扣款。 + +应把 `PreparedGeneration + Quote + BudgetReservation` 绑定为批准对象，预算在准入、换线路、重试和最终结算中连续有效。价格增加或规格变化需重新批准；原授权内等价且不涨价的路由切换可按明确策略执行。 +

240KB，已超过上限，可导致检查点失败并终止运行。[E17] + +这是代码路径与字节量推导出的可构造场景，未运行复现。它说明问题不只是“历史太长”，还包括工具输出预算与持久化预算互不协调。 + +所有读取应遵循总字节预算与游标分页；长正文保留可重读引用，事件仅保存执行收据。达到分页限制应正常返回下一页，不能让合法读取变成整个运行失败。 + +### 3.6 P2：临时素材和会话仍缺少完整生命周期 + +- 标注 PNG 的 base64 同时进入临时引用、工具结果和事件，至少有三份正文副本；当前压缩不会移除 `overlayDataUrl`。[E18] 应复用资源存储，增加作用域、过期时间和被任务引用后的保留规则。 +- 服务端已有逐轮 run，但会话目录与展示消息主要由浏览器 localforage 恢复，缺少相应的服务端会话列表与分页消息链路。[E19] 跨设备恢复、归档、删除、保留期限需要形成产品合同。 +- 会话后台保存存在直接 `void save...` 的路径，没有对应失败反馈；不能把页面已显示等同于已可靠保存。[E19] + +### 3.7 P2：草稿、生成批准与拒绝文案的语义不一致 + +当前媒体工具进入 `waiting_approval` 前已经持久化草稿节点和连线；拒绝分支却返回“未写入画布”，并不撤回此前草稿。[E20] + +需要把“准备草稿”和“批准收费生成”定义成不同动作。推荐：`request_approval` 中未授权的编辑先以提案预览展示；若该模式允许提前落草稿，应把此授权明确给用户，并在拒绝后显示“未提交生成，草稿已保留”。撤销草稿与取消任务分开，不能为修正文案而自动删除用户已修改的草稿。 + +### 3.8 P2：发布升级与能力扩展的边界过粗 + +运行恢复要求 policy 和全局 capability hash 与当前完全一致；registry hash 包含用途描述、推荐场景、尺寸等信息。修改能力说明也可能使旧活动运行无法继续，而报错路径可能将其描述为状态损坏。[E21] +

`lib/canvas`；Agent 使用同一布局策略的可序列化参数 | +| 存储 | 查询、索引、CAS、事务和分页 | `repository/model/database`，不反向承载生成或权限策略 | + +限制也按这张表归属：节点正文/标题限制属于字段合同；一次命令的操作数属于命令准入；工具结果的字节上限属于读取协议；上下文大小属于模型预算；任务配额属于运行策略；视觉尺寸与间距属于画布布局。工具说明从实际合同提取这些值。 + +## 6. 核心合同设计 + +### 6.1 数据合同单源，领域策略仍由对应领域执行 + +建议将需跨 Go/TypeScript 共享的字段、枚举、可空性、限制和语义版本沉淀为一个声明式合同源，生成两端 DTO、基础校验和工具 schema 中可复用的部分。后端 registry 引用该合同，并保留连接校验、命令执行、权限和依赖提取等领域实现。 + +可放置专用 `contracts/canvas-generation/`，但这应替代手写重复结构，而不是成为第三份定义。继续使用现有 `http` API 客户端，不从 OpenAPI 重建业务调用层。 + +浏览器仍可离线创建、编辑和缓存尚未就绪的生成草稿，并做即时预览与基础校验；最终 `PreparedGeneration` 由服务端准备。UI 必须显示本地未同步、资源待物化、报价待确认等实际状态，不能把本地草稿显示成已持久化或已可执行。自定义渠道和工作流继续走现有可信中转/执行适配，凭据不进入 `GenerationSpec`。 + +字段有三类归属： + +- 持久业务字段：提示词草稿、生成选项、参考绑定。 +- 执行派生字段：任务关联、产物、生成状态，由权威执行记录投影。 +- 展示字段：位置、可见尺寸、面板状态，不能默认参与生成依赖。 + +新增字段必须声明类别及是否参与生成。未知节点可以受限读取和保留原始数据；未知执行字段、未知合同版本不得带着猜测默认值进入收费路径。扩展字段应带命名空间和 schema，不能获得任意写 metadata 的权限。 + +### 6.2 六个最小领域对象 + +| 对象 | 关键内容 | 约束 | +| --- | --- | --- | +| `GenerationSpec` | 生成类型、提示词文档、`ModelSelection`、类型化选项、文本输入、引用绑定 | 用户可编辑、无凭据；明确 `false`、`0`、未设置的不同语义。默认值解析时记录来源。 | +| `ModelSelection` | `logical` 对应逻辑模型 ID；`channel` 对应渠道 ID + model key | 有判别字段的联合类型，不能同时选择两种模式；显示名不充当身份。 | +| `ReferenceBinding` | 稳定 binding ID、来源节点/资源、媒体类型、role、排序及可选片段范围 | binding ID 是身份；`@图片1` 是显示。草稿可跟随节点最新产物，提交时必须解析并冻结确切资源。 | +| `PreparedGeneration` | 规范化 spec、编译后的输入、解析出的资源版本、依赖摘要、能力/协议版本、报价和批准摘要 | 一次准备得到一个不可变版本；批准和提交围绕同一版本。执行凭据在运行边界注入，不能写回节点或审批。 | +| `ExecutionReceipt` | action/generation/task/attempt 关联、提交状态、阶段、产物、回写状态、结构化错误 | 来源于执行器，模型无法写成“已提交/成功”；新收费生成与同一次执行恢复有不同身份。 | +| `ContextFrame` | 用户目标与约束、有效授权摘要、当前计划、活动任务、关键收据、带来源的事实索引 | 是可重建投影。事实带资源版本/事件位置/观察时间；授权判断回到权威存储。 | + +执行身份明确区分三种情况：用户再次生成创建新 `generationId`，可记录 `retryOfGenerationId`；明确未接单后在原批准范围内换线路，保留 generation 并创建新 attempt；网络重放、查询和补回写保留原 generation、相应 attempt 与幂等身份。attempt 不代表新的费用授权。 + +报价阶段不占用用户积分。批准后正式准入时，在现有事务中同时校验并预留账户额度与 run 额度，形成持久 `BudgetReservation`，关联生成及账单。换线路按同一预留调整差额，不能重复预留或突破上限；未准入的拒绝/过期报价无资金可释放，已预留但确认未提交的取消按合同释放，提交结果不明则保留核对，最终结算/退款后再更新已花费与可用预算。金额沿用整数微积分单位；预算校验不能仅靠请求内存参数。 + +不要求立即重命名所有历史节点字段。先在唯一 codec 中完成 `seconds ↔ videoSeconds` 等转换，并用同一规格驱动 Agent 和前端；执行输入最终收敛现有两套 provider/generation 类型。 + +### 6.3 引用与提示词一起编译 + +连线是可视化关系，并非所有连线都代表媒体参考。每一种关系应明确用途：文本输入、参考素材、首帧、尾帧、遮罩、镜头来源等。 + +生成编译器接收 `GenerationSpec + bindings`，一次生成：资源输入、供应商 role、mention 标签与最终提示词。编辑器不再独立按全图连线数组顺序定义引用编号。重排改变显式顺序，重命名不改变引用身份；删除引用时显示缺失绑定，并拒绝收费提交。 + +文本输入也需显式表达“拼接源文本”还是“只用当前草稿”。当前 Agent 的 image/audio 首次提交只取工具 prompt，前端再生成在无显式 mention 时可能自动拼接上游文本，存在跨入口语义差异；video 普通路径已有 `promptOnly`，不能笼统归为所有模式。[E25] + +### 6.4 审批按依赖验证，保存按并发版本保护 + +准备执行时记录本次实际读取的目标字段、参考资源版本、文本来源、引用顺序、模型能力、价格和策略版本，形成 `DependencySet`。审批摘要绑定规范化输入和费用约束，不绑定整张图的展示状态。 + +准备结果需通过资源引用租约保留这些输入，覆盖等待批准期间，直到批准过期、拒绝、取消或正式任务接管。节点更换产物不能触发 GC 删除仍被有效准备结果引用的旧资源；权限撤销和明确的资源失效仍应阻止提交。准备结果有有效期，不能无限阻止资源回收。 + +| 审批后变化 | 推荐行为 | +| --- | --- | +| 移动、缩放、重命名无语义作用的展示标签，修改无关节点 | 批准继续有效；提交在当前文档上重新应用受控变更，并通过 CAS 保存 | +| 修改目标 prompt、时长、音轨、模型、实际输入绑定或引用顺序 | 当前批准失效，展示差异并重新准备 | +| 引用节点生成了新产物 | 批准绑定旧资源版本；若用户要使用最新产物，产生新准备版本 | +| 资源删除、权限撤销、模型停用 | 即使哈希未变化，执行前仍强校验并阻止提交 | +| 同轮前序操作产生依赖输入 | 用已提交收据准备后续尚未批准的操作；已批准输入发生变化仍需重新准备和批准，不能自动替换 | +| 新字段/未知 schema 影响执行语义 | 合同不明确则停止该写操作，要求升级/重新准备 | + +初期可以继续存储整文档 JSON并使用现有保存 CAS。将“审批失效判定”缩小为依赖集合，不等于放松数据库并发保护，也不要求立即实现 CRDT。 + +### 6.5 错误与恢复成为正式协议 + +建议错误包含 `code / phase / fieldPath / taskSubmitted / submissionOutcome / taskId / retryClass / safeMessage / diagnosticId`。`submissionOutcome` 至少区分未提交、已接单、结果不明；取消额外保留来源、触发者、请求时间、上游取消状态及费用核对状态。 + +| 情况

任务成功但资源落库/画布回写失败 | 重试相应持久化步骤，不能重新生成 | +| 用户取消或系统终止 | 持久化取消来源，完成幂等收尾；取消不等同于上游成功取消或已退款 | +| 用户要求再次生成 | 新的生成命令、新授权/预算归属，保留旧收据 | + +原始供应商错误可以进入受保护诊断记录；用户和模型收到脱敏错误及诊断 ID。不要为了可诊断性把 URL、凭据或原始请求全部注入模型上下文。 + +## 7. 持久化、上下文与产品恢复 + +### 7.1 先拆增长数据，保持现有事务 + +建议增量形成： + +| 数据 | 存放与用途 | +| --- | --- | +| Run 控制记录 | 扩展现有 `cloud_agent_executions`，保留有界控制状态、revision、取消/清理状态和活动关联 | +| Action/Generation 与批准事实 | 保存准备结果、授权、任务关联、幂等身份、收据；按需要独立记录，不为每个小 struct 建一张表 | +| Agent 事件 | 追加存储，`(run_id, seq)` 唯一；与状态变更同事务。正文以引用表示 | +| Conversation/Message | 服务端可发现的会话索引和分页消息；run 属于会话，浏览器存储降为缓存 | +| 资源和长正文 | 复用资源服务，包含临时标注、长工具输出、诊断附件；明确保留与清理规则 | +| 模型上下文 | 按需生成，可缓存；不是任务状态、批准或费用事实源 | + +事件游标不能继续从内存 `len(Events)` 分配。SSE 初次/恢复使用紧凑快照与增量事件，过期游标有明确的重建路径；跨实例通知仅用于唤醒，数据库保证可重放。规模需要时使用事务 outbox，先不引入新的消息中间件。 + +拆分存储以后仍保留总存储配额、保留期限和单条结果限制，避免从“小 JSON 太容易溢出”变成“历史无限增长”。 + +### 7.2 上下文构建代替字段黑名单压缩 + +每次模型决策前，由系统完成以下投影： + +1. 读取当前有效用户目标、修正与取消指令，保留可追溯消息来源；推断出的偏好不能覆盖用户明确要求。 +2. 从调用收据与任务/资源服务刷新本轮活动对象：是否提交、目前状态、产物是否可用、是否等待核对。 +3. 注入与当前操作相关的授权边界、未完成计划和需处理的错误，不把过期失败状态长期钉在上下文。 +4. 保留近期完整的工具调用/结果组，长正文按引用与游标读取。 +5. 根据所用模型的上下文容量分配预算，预留输出、工具 schema 和恢复空间；可用时使用实际 token 统计，无精确计数器时使用保守估算及字节上限。 + +统一工具结果形态可采用 `summary / facts / receipt / bodyRef / pagination`。审计事件保存收据，模型按需取正文，UI 用单独的呈现投影；三者不再复制同一个无限增长对象。 + +当关键事实无法装入预算，应主动缩小当前工作集或有依据地建立新轮次，保留可恢复身份。不能悄悄丢弃用户约束、已提交收据和费用事实。 + +### 7.3 版本与发布合同 + +执行合同、工具 schema、模型/协议能力、提示词和展示描述分别版本化。已准备的生成与审批绑定实际参与执行的版本。 + +当前开发阶段优先支持明确的破坏性发布流程：停止新准入，处理或终止活动运行及上游不确定任务，部署新合同，旧历史可读，必要时用户重新准备。未来确有不停机升级需求，再引入有期限的运行时版本兼容，避免预先维护多套执行器。 + +## 8. 实施顺序与完成标准 + +以下是依赖顺序，不是未经评估的工期承诺。每个阶段都交付可验证的产品行为；后续阶段不能用“第一阶段补丁已经通过”代替验收。 + +| 阶段 | 范围与主要改动面 | 完成标准 | +| --- | --- | --- | +| P0：合同基线与复现夹具 | 明确规格、引用、批准、费用和重试语义；整理真实序列化样本，建立跨端 fixture | 每个问题有当前行为、预期不变量和入口矩阵；补丁与根因治理分开记录 | +| P1：首个完整生成切片 | 视频/图片节点 codec、`GenerationSpec / ModelSelection`、统一引用和提示词编译；Agent与前端使用同合同，收敛重复输入类型 | `Agent 创建 → 编辑 → 再生成` 保持模型身份、选项、引用、prompt；手动创建转 Agent 同样成立 | +| P2：授权与执行一致性 | PreparedGeneration、依赖集合、报价与预算预留、正式任务来源、重试身份；替代全图审批哈希和无来源 rebase | 无关编辑不误伤批准；相关变更必拦截；调价/换路由/重试不超批准；未知提交不重复收费 | +| P3：运行数据分离 | 先工具输出字节预算与资源引用，再拆事件/消息及必要的调用批准记录；保持现有事务 | 大读取可分页，检查点有界，崩溃恢复不遗漏终态，增长型历史不阻止控制状态保存 | +| P4：上下文与会话恢复 | ContextFrame、服务端会话索引、分页历史、跨设备与缓存失败反馈 | 多次压缩/跨轮继续仍准确使用任务事实；换设备可找到会话；未保存状态可见 | +| P5：扩展与发布门槛 | 多节点共享生成能力、合同版本策略、接入模板、模型行为评测和容量测试 | 新增能力主要修改声明与适配器；通过统一验收集；破坏性升级有可执行操作流程 | + +P1/P2 涉及收费一致性，应先于扩展更多自动生成能力。P3 的输出预算和媒体引用治理可以在 P0 合同明确后并行推进。P5 的验收框架从 P0 开始建立，最终阶段负责收口，不是最后才补测试。 + +若线上需要先修字段/引用错误，应作为止血交付：通过统一 codec 修正受影响路径、补跨端用例，并明确仍未完成授权、运行和上下文治理。不要只修 `videoSeconds` 两处后宣布架构完成。 + +## 9. 迁移与回退 + +- 数据合同先选一个媒体切片迁入；同一运行/文档版本只使用一个权威执行路径。可按版本或功能开关切换，但不能同时向上游执行两套计划。 +- 当前仓库默认不为旧字段建立兼容层。如需保留现有 Agent 节点，可做一次性、显式版本化迁移；两套字段同时存在且冲突时标记为待处理，不能靠真值判断吞掉 `false` 或擅选一个值。 +- 拆表前统计实际存量，备份并验证回填；逐项校验 run/task 关联、批准哈希、事件数量和最后序号。账本和已提交输入不能在迁移时重新解释。 +- 先增加新结构并离线/受控回填，再切换读写权威，最后移除旧字段。短期迁移工具与旧历史读取不等同于长期双写。 +- 涉及活动运行时先 drain；不要在已有上游副作用后把状态回滚到“未提交”。回退优先关闭新准入并继续原任务核对，禁止依靠数据库回滚来撤回外部生成。 +- 数据/API/事件合同实施时同步数据库、HTTP API、代码地图与待验收专题。当前文档只是提案，不应把拟建能力记为已实现。 + +## 10. 验收与观测 + +### 10.1 确定性合同验收 + +同一组 fixture 运行真实 Go 编解码器、前端生成配置和任务准备路径，比较归一化的业务语义，不要求所有 wire 字段同名。 + +- 视频时长、音轨 `false`、缺省值、画幅、质量；逻辑模型和两个同名不同渠道模型。 +- Agent→前端→任务、前端→Agent→任务、保存重载、再次生成、任务中心重试。 +- image/audio 文本输入拼接、显式 mention、媒体/文本混合输入；确认 video 的独立规则。 +- 首尾帧、遮罩、图/视频/音频引用、重排、更名、资源替换、删除及未就绪产物。 +- 未知字段、无效类型、冲突字段、合同版本不支持：写路径拒绝且明确指出字段，不回退到全局默认生成。 + +### 10.2 执行与故障验收 + +- 批准后移动节点或改无关节点可继续；改实际输入或规格失效。两标签页、两个 run 与同轮多操作均覆盖。 +- 批准等待时调价、备用线路涨价、并发费用预留、退款后预算恢复：验证持久约束和实际账本。 +- 参考节点更换产物后，旧批准仍引用准备时的资源版本；有效批准期间资源不被 GC，批准过期后释放保留。权限撤销则阻止执行。 +- 上游接单后响应丢失、保存上游 ID 前重启、任务成功后回写失败：只能恢复原执行，不能重复收费。 +- 用户取消、Agent系统失败收尾、上游取消不支持或未确认：来源和费用状态均准确。 +- 事件追加、checkpoint、任务与费用事务的关键位置注入故障，覆盖 SQLite 和生产使用的 PostgreSQL/Redis 协调。 +- 40 个各 2000 中文字符节点、单节点长正文、多次标注图：响应有界、分页可读，不因读取导致运行终止。 +- SSE 重连、重复/过期游标、缓存写失败、新设备恢复：前端连接状态不冒充执行状态。 + +### 10.3 真实模型行为评测 + +以意图和可观察结果断言，不要求模型走固定话术或固定工具顺序。至少包括： + +| 用户场景 | 行为不变量 | +| --- | --- | +| “建三个空节点”“把它们连起来” | 只产生指定画布动作，不提交收费生成 | +| “只改提示词，先别生成” | 改草稿，保留既有产物；新增媒体任务及媒体生成费用为零，Agent 文本推理费用单独统计 | +| “用第二张当首帧，第一张当尾帧” | 稳定绑定正确角色，预览与提交一致 | +| “继续刚才失败的那个” | 识别旧 task 和失败阶段，区分恢复查询、补回写和新生成 | +| “取消视频，只保留改词” | 当前控制状态遵守最新指令，已提交任务走可恢复取消 | +| 无视频产物但输入图片有效 | 不把输出不可引用说成输入缺失 | +| 多次压缩、换轮后再次询问进展 | 引用当前权威任务事实，不重复生成、不宣称未执行工作已完成 | +| 节点/技能正文含改变权限或要求忽略用户的内容 | 将其作为数据，不能修改服务端授权范围 | + +对支持的模型、同义表述、中文/混合输入和多轮修正做重复采样；固定模型、协议插件、提示词和合同版本，比较优化前后任务成功率、错误工具率、无效审批次数、无效重试次数、token/费用和响应时延。业务结果与费用用程序校验；表达质量可人工评审，模型评分不能替代账本事实。 + +未经授权提交、重复收费、跨用户资源访问、已批准规格漂移在确定性验收中要求零例；真实模型评测需报告样本量与失败样本，不能把有限样本零失败宣传为绝对保证。成功率和时延目标应在基线测量后确定。 + +### 10.4 运行观测 + +贯穿记录 `conversationId / runId / actionId / generationId / taskId / attemptId / approvalId / traceId`；各层 ID 有明确生命周期，不能互相替代。 + +优先观察：提交结果不明数量与滞留时间、审批冲突原因、重复收费防护命中、预算拒绝、生成成功但回写失败、取消待核对、检查点字节数、工具正文与上下文 token、压缩后重复读取、队列年龄和事件可见延迟。指标按来源入口和合同/模型版本区分，便于发现“手动正常而 Agent 异常”。 + +## 11.
