收紧编辑器内部处理元数据边界

普通用户与公开响应统一移除生成 provider、内部处理模型和抠图审计字段。
普通生成请求移除 segModel，由后端固定抠图策略并清理客户端伪造的保留字段。
手动去背景继承可信源模型，角色动作与去背景失败统一使用稳定用户文案。
后台原始审计继续保留真实 provider 与抠图模型，并补齐 Owner、Public、Admin 和紧凑结果测试。
同步更新前端响应契约、外部 OpenAPI、后端架构文档和项目决策记录。

+## 2026-07-31 修正抠图内部元数据的普通用户读取边界
+
+- 背景：2026-07-30 的记录误把素材 owner 与后台审计并列为原始抠图执行信息的读取方。owner 是普通用户，前端不展示字段不能阻止其从项目资源、素材库、精选提交 / 点赞回包、画布布局或任务完成响应的网络 payload 读取 BgFilter、阿里云、本地键色、具体分割模型或背景色。
+- 决策：本条取代 2026-07-30 决策中“素材 owner、精选提交响应仍可读取原始值”的表述。普通用户（包括素材 owner）和匿名公开读取必须共同过滤素材顶层 `provider`、内部处理 `model`，以及 `generationInputs` 顶层 `screenColorHex`、`mattingProvider`、`mattingModel`；正常用户可见生成 `model` 和其他合法功能性顶层字段（例如 `characterAnimation`）保持不变。User/Owner mapper 先完成该清理，public mapper 在其基础上叠加公开字段规则；后台管理与服务端审计继续使用 raw mapper 和持久化原值。历史数据不迁移，统一在读取边界清理。
+- 入站与持久化：客户端提交的 `generationInputs` 不得伪造上述内部键，服务端在实际处理完成后才写入可信值。手动去背景的正式素材 `model` 必须继承经服务端验证的正常源生图模型；若来源或祖先链不存在正常模型则为 `null`，不得写入 `BgFilter complex` 等内部处理模型。内部抠图 provider / model 可继续持久化供后台审计，普通用户完成响应和用户可见错误文本均不得暴露它们；手动去背景与角色动作透明化失败在 Owner HTTP / 任务状态边界统一替换为稳定业务文案，原始错误只留在任务记录、tracing 和后台审计。
+- 影响范围：项目资源、素材库、精选提交 / 点赞、图片 / 图标 / 视频 / 音频 / 角色动画生成完成、Agent 紧凑结果和识别出的画布资源 / 图层快照的 User/Public mapper；手动去背景持久化和完成响应；External Editor API 创建素材 / 资源时的保留键入站清理；相应 API / OpenAPI 契约、前端搜索 / 详情 / ZIP 过滤测试与后台 raw 审计测试。不修改 SpacetimeDB schema、迁移或 bindings。
+- 验证方式：Owner 和匿名响应覆盖无 `provider`、无内部 `model`、无三个内部 `generationInputs` 键，且正常 `model` 与 `characterAnimation` 仍保留；Admin raw payload 保持完整。覆盖历史 `BgFilter complex`、三类入站伪造键、手动去背景源模型回溯和用户错误文本过滤；运行 api-server 定向测试、前端定向测试、`cargo check -p api-server --manifest-path server-rs/Cargo.toml`、`npm run typecheck`、`npm run check:encoding` 与 `git diff --check`。
+- 关联文档：`docs/【后端架构】server-rs与SpacetimeDB数据契约-2026-05-15.md`、`docs/technical/【前端架构】图片画布编辑器MVP接入方案-2026-06-11.md`。
+
+---
+
 ## 2026-07-30 图片画布搜索不得索引内部模型和 Provider
 
 - 背景：素材和图层详情虽已把内部处理模型显示为 `-`，搜索仍索引原始 `model` 与 `provider`，导致 `BgFilter complex`、`segment-common-image`、`BgFilter` 或 `Aliyun Matting` 等隐藏信息可被查询命中，并出现“命中但无可见匹配字段”的异常体验。
