Introduce a new UI design asset extraction flow: add POST /api/editor/ui-designs/assets/extractions handler that always uses gpt-image-2 with the fixed prompt "提取画面中的所有独立并整理成spritesheet"; parse Data URL references, call OpenAI image edits, return a spritesheet and sliced icon assets. Increase request body limit for image Data URLs and wire the route with bearer auth. Add platform-image slicing: slice_generated_icon_spritesheet_all_by_connected_components (with auto-naming "素材 1..N", foreground estimation and heuristics) and export it. Add Rust tests for the handler, prompt constant, and slicing behavior. Update frontend client and integration tests to call the new extractEditorUiDesignAssets API and verify spritesheet + icon layers are added to the canvas and persisted. Update multiple docs to describe the extraction UI, toolbar placement, and related audio/playback pitfalls. Minor related updates: toolbar button ordering and audio duration / signed read-url notes.
server-rs 工作区说明
更新时间：2026-05-15
server-rs/ 是当前唯一后端工作区，承载 Rust api-server、SpacetimeDB module、领域模块、平台副作用适配和共享契约。旧 server-node、Express、PostgreSQL、Go 服务端和 maincloud 口径均为历史残留，不再作为当前实现目标。
当前职责
crates/api-server：Axum HTTP / SSE / BFF 门面、鉴权、中间件、外部服务编排和 DTO 映射。crates/spacetime-module：SpacetimeDB 表、reducer、procedure、事务 adapter、row mapper 和迁移。crates/spacetime-client：后端访问 SpacetimeDB 的 typed facade。crates/module-*：领域模型、命令、应用规则、领域事件和领域错误。crates/platform-*：OSS、LLM、语音、认证等外部平台能力。crates/shared-contracts：前后端共享 DTO 与公开契约。crates/shared-kernel、crates/shared-logging、crates/tests-support：跨模块基础能力、日志和测试支撑。
开发规则
server-rs/Cargo.toml是 workspace 成员和依赖版本事实源；第三方依赖和 workspace 内 crate path 优先放在[workspace.dependencies]。module-*不直接依赖 Axum、SpacetimeDB table/reducer/procedure、reqwest、OSS、LLM、spacetime-client、tokio或文件系统。api-server不承接领域真相；发现领域规则时优先沉到对应module-*。- SpacetimeDB schema 变化必须同步
spacetime-module/src/migration.rs、生成绑定和当前后端架构文档的表目录。 - 人工命令、本地联调和文档示例不要使用
spacetime --root-dir。
常用命令
cargo check -p api-server --manifest-path server-rs/Cargo.toml
cargo test -p api-server --manifest-path server-rs/Cargo.toml
npm run check:server-rs-ddd
npm run check:spacetime-schema
npm run spacetime:generate
npm run api-server
涉及 API smoke 时用 npm run api-server 启动后端并检查 /healthz，不要使用旧 api-server:maincloud。
