Per docs/zh/plans/render-pipeline-threads.md §3.8: - oak-node/nodes/graphendpoints.rs: the GraphInput/GraphOutput virtual node pair — factory-registered but hidden from every create menu, duplicate refused, real value() semantics (the input forwards its feed_in row, the output publishes its tex_in as the frame). The input endpoint also declares a connectable feed_in port (documented deviation: footage/generator sources have no connectable inputs, so the walk needs a feeder anchor). - graph.rs: ensure_endpoints/endpoints/is_endpoint — idempotent, identified by type id, default input->output edge only while the output's tex_in is free; remove_node refuses endpoints. - project.rs + serializer.rs: every project graph carries the pair; a legacy file without endpoints migrates on load (roundtrip and legacy-migration tests, re-save is idempotent). - traverser.rs: eval_graph_bfs — the endpoint-to-endpoint Kahn sweep. Live set = (input's forward cone U its feeder cone) INTERSECT (output's backward cone); multi-input nodes dequeue at zero in-degree over the live subgraph; deterministic ascending-id ready order (Graph::edges is a BTreeSet, so insertion order is unrecoverable — documented); time-shifted upstreams pull through the shared DFS memo (walk_dfs, factored out of evaluate); un-orderable remainder reports a named cycle; missing endpoints / unreachable output are errors. Eight BFS tests cover the plan's acceptance bullets. - oak-render: bfs_endpoint_sweep_renders_footage_through_position — real clip through a real Position node via the sweep, shifted pixels asserted against a reference decode. - Endpoint names localized in all eight i18n packs; storage/structure tests updated for the two extra nodes.
长期计划（plans）
本目录收纳 Oak 的中长期规划文档与并行执行计划。已完成的战役
文档归档在 completed/；进行中的计划在下方目录。
目录
| 文档 | 内容 | 启动前提 |
|---|---|---|
ai-agent-design.md |
AI Agent 插件设计（已按 OPP/1 重写）：多模态 LLM 作为外部插件经策展工具面自动剪辑，render.* 取帧回喂形成"编辑→看图→再编辑"视觉闭环；事务化编辑、双层确认、声明式 AI 面板、Mock LLM/回放夹具测试、A1–A5 里程碑 |
external-plugin-system P1–P3 完成（面板需 P4） |
external-plugin-system.md |
外部功能插件系统：插件=独立进程（非库加载），JSON-RPC over stdio 控制面 + shm 数据面（泛化 M15 render-worker 传输）；策展宿主 API（事务化可撤销编辑、取帧回喂 AI）、声明式/像素面双 UI 路径、能力位与确认模式；含与 ai-agent-design.md 的关系与 P1–P6 里程碑 | 已解锁（RIIR + M15 完成），随时启动 |
external-plugin-protocol.md |
插件协议规范 OPP/1：NDJSON 分帧 + JSON-RPC 2.0 双向信封、握手/心跳/关闭、全量方法/事件/错误码、编辑事务协议、shm 数据面（无头部无锁）、声明式与像素面 UI 协议、限流配额、版本演进规则、AI 粗剪报文示例 | 随 external-plugin-system 启动 |
render-pipeline-threads.md |
渲染管线改造：单解码线程 + 单渲染线程 + 主进程上屏（GPU 单队列，多进程无意义）；解码硬解优先且零拷贝（FFmpeg hwaccel 经 DMA-BUF/DXGI/IOSurface/CUDA 导入，CPU 解码上传仅 fallback，手写 GPU 解码为次选）；OpenFX 收编进唯一隔离进程；decode→render→present 三队列流水线；内置效果全 GPU 零拷贝；resolve 重写为 match+Job 单循环并升级为 Job 图（GraphInput/GraphOutput 虚拟端点可见、禁删，从输入节点 Kahn 形态 BFS 至全部分支汇聚输出节点）；M0a–M5 里程碑 | 已解锁，随时启动（M0a 独立先行） |
