Keep the demo coherent across paper, code, evidence, and UI. The user should be able to rehearse the demo, regenerate artifacts, and explain every visible panel from code-backed facts. + +The central story is: + +1. A public vulnerability-intelligence stream arrives from sources such as NVD, vendor advisories, CISA KEV/alerts, and research notes. +2. SAGE normalizes and schedules the application workflow. +3. SageFlow provides vector-window operators such as join, filter, window, and ITopK for semantic-state materialization. +4. BriskSnapshot exports bounded, application-readable contracts: snapshot, routing, and escalation. +5. The UI shows both the live replay path and prepared variants for threshold, retention horizon, and arrival order. + +## Hard Guardrails + +- Never create `.venv` or `venv`; reuse the configured Conda or existing non-venv Python environment. +- Do not introduce new `ray` imports or dependencies. SAGE is FlowNet/stream-first, and this demo should stay local, service-shaped, and stream-first. +- Fail fast with actionable errors. Do not add silent fallback logic that hides missing `sage`, `sage_flow`, dataset, or UI backend problems. +- Do not add local editable installs of sibling SAGE subpackages to setup scripts or docs. Use explicit `PYTHONPATH` for local demo commands when needed. +- Keep SAGE core clean: do not move demo UI, app-specific code, or paper-only utilities into `SAGE/src/sage`. +- Keep claims honest. The current demo uses a long-lived SAGE `BaseService` wrapper and a persistent Python-side adapter, while SageFlow `StreamEnvironment` instances are still short-lived inside adapter calls. Do not claim a persistent native C++ SageFlow execution graph unless it has been implemented and validated. +- Treat prepared evidence as evidence, not as fake live execution. If numbers are shown in the paper/UI, they must be traceable to `prepared_demo_evidence.json`, `prepared_demo_run.json`, or an explicitly documented measurement script. + +## Repository Map + +### SAGE Core (`/root/SAGE`) + +Use SAGE only through stable public surfaces: + +- `sage.foundation`: function bases, configuration, `SagePorts`, user paths. +- `sage.runtime`: `LocalEnvironment`, `BaseService`, service registration, job execution. +- `sage.stream`: dataflow composition surface. +- `sage.serving`: serving integration and gateway helpers when needed. + +Respect the current 4-layer direction: + +- L4 application repos -> L3 `sage.cli` -> L2 `sage.runtime` / `sage.stream` -> L1 `sage.foundation`. +- Demo code belongs in application/demo repos, not in lower layers. + +Use `SagePorts` from `sage.foundation.config.ports` for SAGE-owned service ports. Legacy UI-specific ports are not part of SAGE foundation; BriskSnapshot's live backend currently uses `BRISKSNAPSHOT_LIVE_PORT` with default `8765` in the UI repo. + +### SageFlow Engine (`/root/sageFlow`) + +SageFlow is a C++20 vector-native stream processing engine for semantic state snapshots. Its demo-relevant operators are: + +- `Join`: vector similarity join over bounded windows. +- `Filter`: candidate filtering before downstream operators. +- `Window`: count/time-bounded state materialization. +- `ITopK`: representative context retrieval for routing-style demos. + +Key files to inspect before changing engine behavior: + +- `docs/JOIN_PIPELINE_GUIDE.md` +- `include/operator/join_operator.h` +- `src/operator/join_operator.cpp` +- `include/operator/join_operator_methods/` +- `include/operator/utils/join_strategy_config.h` +- `src/operator/join_strategy_factory.cpp` +- `src/operator/utils/join_config_validator.cpp` +- `test/test_utils/` + +Join and state invariants: + +- RoundRobin partitioning needs shared state for reliable recall. +- Partitioned strategies need matching partitioned state and index strategy. +- ClusteredJoin requires `num_partitions == parallelism`. +- All index operations must go through `ConcurrencyManager`; do not directly manipulate index internals. +- QIQ-style paths are experimental/unsafe unless explicitly enabled and justified. + +When changing SageFlow C++ build/test behavior, use the VS Code CMake Tools build/test tools. For Join-related changes, run the relevant Join integration tests, especially `test_join_datasource_modes` when datasource modes or Join pipeline behavior changes. + +### SAGE Examples Demo (`/root/sage-examples`) + +The ICPP demo's application contract lives in `sage-examples/apps/src/sage/apps/sageflow_service_demo/`. + +Important files: + +- `examples/run_sageflow_service_demo.py`: console/JSON entry point. +- `apps/src/sage/apps/sageflow_service_demo/models.py`: payload contracts shared with the UI. +- `apps/src/sage/apps/sageflow_service_demo/operators.py`: SAGE operators and service-call steps. +- `apps/src/sage/apps/sageflow_service_demo/workflow.py`: `LocalEnvironment`, `BaseService`, and pipeline wiring. +- `apps/src/sage/apps/sageflow_service_demo/adapter.py`: SageFlow adapter used by snapshot, triage, and security paths. +- `apps/src/sage/apps/sageflow_service_demo/demo_data.py`: demo datasets and replay ordering. + +Current pipeline facts: + +- Snapshot path: dual-source events -> normalize -> embed -> `SageFlowDualSourceSnapshotStep` -> derive correlated/emerging insights. +- Triage path: events -> normalize -> embed -> SageFlow Top-K context -> route decision. +- Security path: events -> normalize -> embed -> SageFlow security pattern query -> escalation signal. +- Embeddings are deterministic hashed vectors in `EmbedTextSignalStep`, so demo replay should be reproducible. +- `InMemorySageFlowSnapshotAdapter` delegates pair discovery and filtering/top-k steps to `sage_flow`, but it also keeps Python-side window lists and builds application snapshots in Python. + +Useful local command for JSON output: + +```bash +cd /root/sage-examples +PYTHONPATH=/root/SAGE/src:/root/sage-examples/apps/src:/root/sageFlow \ +python examples/run_sageflow_service_demo.py --json --dataset medium +``` + +### BriskSnapshot UI (`/root/brisksnapshot-ui`) + +The UI is the audience-facing console. Keep it as an operational demo surface, not a marketing landing page. + +Important files: + +- `src/types.ts`: canonical TypeScript contract for UI payloads. +- `src/App.tsx`: main React application and live API calls. +- `src/data/demoData.ts`: built-in scenario, variant metrics, pipeline panels, and prepared outcomes. +- `src/styles.css`: layout and visual system. +- `backend/live_demo_server.py`: lightweight live replay server that drives `InMemorySageFlowSnapshotAdapter` one event at a time. +- `README.md`: run/import instructions. + +Current live API facts: + +- Frontend expects `LIVE_API_ROOT = http://127.0.0.1:8765`. +- Backend endpoints: `GET /health`, `GET /api/live/state`, `POST /api/live/start`, `POST /api/live/reset`, `POST /api/live/stop`. +- Backend port is controlled by `BRISKSNAPSHOT_LIVE_PORT`, default `8765`. + +Useful commands: + +```bash +cd /root/brisksnapshot-ui +npm run backend +npm run dev -- --host 0.0.0.0 --port 4173 +npm run build +``` + +UI rules: + +- The first screen should be the usable demo console: replay controls, state counters, pipeline trace, runtime view, snapshot/clusters, outputs, and metrics. +- Preserve the data contract in `src/types.ts`; update the backend, prepared data, import parser, and UI together when a field changes. +- Do not add visible instructional copy that explains how the UI works unless the demo script explicitly needs it. Let controls and labels carry the interaction. +- Keep panels dense, readable, and stable under live updates. Avoid layout shift from changing labels, metric values, or long event IDs. +- When adding icons or controls, prefer familiar UI affordances and keep the interface suitable for a systems demo. + +### ICPP Paper and Prepared Evidence (`/root/sageFlow/docs/paper-icpp-demo`) + +Important files: + +- `acmart-primary/main.tex`: ACM demo paper. +- `acmart-primary/data/prepared_demo_run.json`: baseline replay output contract. +- `acmart-primary/data/prepared_demo_evidence.json`: prepared pipeline/variant metrics. +- `acmart-primary/generated/prepared_run_result_figure.tex`: generated TikZ figure. +- `acmart-primary/scripts/generate_prepared_run_figure.py`: generator for the prepared figure. +- `reference-icpp-style/`: style references for ICPP-style demo writing. + +Paper narrative rules: + +- The paper is about BriskSnapshot as a demo system, not a full SAGE or SageFlow architecture paper. +- Lead with the demo problem: downstream AI services need fresh, bounded semantic state from a streaming runtime. +- Use application-visible evidence: active window size, cluster count, source coverage, emitted contracts, throughput, end-to-end P95, and snapshot-export P95. +- Separate live replay claims from prepared measurement claims. +- Keep the three contracts consistent: snapshot, routing, escalation. +- Do not describe a feature as implemented unless the corresponding code path exists and can run. + +Prepared evidence rules: + +- Treat JSON inputs as the source of truth for generated figures. +- After changing `prepared_demo_run.json` or `prepared_demo_evidence.json`, regenerate `generated/prepared_run_result_figure.tex` with the script. +- Keep metrics synchronized across `main.tex`, generated figures, `src/data/demoData.ts`, and README/demo script notes. +- If numbers differ between generated files and source JSON, stop and reconcile before editing prose. + +## Development Workflow + +1. Identify which layer is affected: paper/evidence, SAGE app pipeline, SageFlow engine, UI backend, or UI frontend. +2. Read the nearest README and the concrete source files listed above before editing. +3. Make the smallest cross-repo change that keeps the demo story and contracts consistent. +4. For contract changes, update Python dataclasses/models, TypeScript types, prepared JSON, UI parsing, and paper tables together. +5. For runtime or adapter changes, verify both console JSON output and live backend behavior. +6. For UI changes, run `npm run build` and, when practical, start the backend and frontend to inspect the demo flow. +7. For paper/evidence changes, regenerate generated artifacts and ensure LaTeX-facing numbers match the JSON evidence. +8. Report exactly what was validated and what was not run. + +## Validation Checklist + +Use the narrowest validation that covers the change: + +- SAGE app pipeline: run `examples/run_sageflow_service_demo.py --json` with the local `PYTHONPATH` command. +- UI type/build changes: run `npm run build` in `brisksnapshot-ui`. +- Live backend changes: run `npm run backend` or `python backend/live_demo_server.py`, then check `/health` or the UI live replay. +- Prepared figure changes: run `python acmart-primary/scripts/generate_prepared_run_figure.py` from `docs/paper-icpp-demo` context or by absolute path. +- SageFlow C++ changes: use CMake Tools build/test; for Join changes include relevant Join integration/performance tests. +- Paper-only changes: inspect generated artifacts and compile/check LaTeX when the environment supports it. + +## Demo Quality Bar + +- A viewer should understand the causal path from event arrival to exported contract. +- Every metric shown in the UI or paper should have a source file or measurement path. +- Every UI panel should correspond to a live or prepared artifact, not decorative filler. +- The demo should remain replayable without hidden manual steps beyond documented commands. +- The final explanation should be able to answer: what state is maintained, who owns it, what contract is exported, and which downstream action consumes it. diff --git a/.github/agents/sageflow.agent.md b/.github/agents/sageflow.agent.md index 02d0c2de..2bcbc81f 100644 --- a/.github/agents/sageflow.agent.md +++ b/.github/agents/sageflow.agent.md @@ -1,306 +1,264 @@ --- -description: "SageFlow 项目专用开发助手,专注于向量流处理引擎的 C++20 开发、测试与调试。" +description: "SageFlow 项目专用开发助手,专注于向量流处理引擎、Join 算子并发路径、C++20 运行时和测试验证。" tools: [ "vscode", "execute", "read", "agent", - "edit", - "search", - "web", "todo", - "vscode.mermaid-chat-features/renderMermaidDiagram", - "github.vscode-pull-request-github/issue_fetch", - "github.vscode-pull-request-github/suggest-fix", - "github.vscode-pull-request-github/searchSyntax", - "github.vscode-pull-request-github/doSearch", - "github.vscode-pull-request-github/renderIssues", - "github.vscode-pull-request-github/activePullRequest", - "github.vscode-pull-request-github/openPullRequest", - "ms-azuretools.vscode-containers/containerToolsConfig", - "ms-python.python/getPythonEnvironmentInfo", - "ms-python.python/getPythonExecutableCommand", - "ms-python.python/installPythonPackage", - "ms-python.python/configurePythonEnvironment", - "ms-toolsai.jupyter/configureNotebook", - "ms-toolsai.jupyter/listNotebookPackages", - "ms-toolsai.jupyter/installNotebookPackages", - "ms-vscode.cpp-devtools/Build_CMakeTools", - "ms-vscode.cpp-devtools/RunCtest_CMakeTools", - "ms-vscode.cpp-devtools/ListBuildTargets_CMakeTools", - "ms-vscode.cpp-devtools/ListTests_CMakeTools", ] --- # SageFlow Development Agent -## 项目概述 +## 项目定位 -**SageFlow** 是一个向量原生流处理引擎,专为实时 LLM 生成任务设计。它提供声明式 API 来组合时间窗口内的有状态向量操作,为动态变化的数据集提供快速、高效的语义上下文更新。 +**SageFlow** 是一个算子多线程的向量流处理引擎,核心目标是在滑动窗口流上维护向量状态、执行相似度查询/Join,并把实时语义上下文暴露给上层 AI pipeline。开发时必须以当前代码为根本事实来源;`docs/`、论文草稿和历史计划只能作为设计意图或背景材料,不能覆盖代码现状。 -## Environment Rule +本仓库属于 ICPP 2026 Demo 多仓工作区的一部分。SageFlow 的职责是内层向量流运行时;不要把 SAGE 编排、demo UI、LLM provider 或实验脚本职责混入 SageFlow runtime 代码。 -- Do not create new local virtual environments (`venv`/`.venv`); use the existing configured Python environment. +## 工作前置规则 -### 核心应用场景 +- 每次修改前必须在本仓库运行 `git status --short`,确认已有用户改动并避免覆盖。 +- 不创建新的 `venv`/`.venv`;使用已有 Python/CMake 环境。 +- 不伪造实验数据、吞吐、召回、延迟、扩展性结论;缺失指标必须标注为 unavailable 或待测。 +- 不打印、提交或硬编码 API key、私有 endpoint、具体 LLM provider/model。 +- 修改 Join、partition、WindowState、index 或 Python binding 后,必须选择与改动匹配的测试/构建命令验证。 +- 工作区根目录不是 git repo;只在 `sageFlow/` 仓库内做本 agent 覆盖的修改。 -- **实时 LLM 生成**: 为大语言模型提供新鲜的、有状态的上下文快照 -- **动态上下文维护**: 适用于具有快速演变上下文的对话式 AI -- **流式向量分析**: 对向量数据进行高速语义查询 -- **自适应推荐系统**: 基于流式事件的实时推荐 +## 代码优先级 -## Agent 职责 +研究或修改行为时按以下证据优先级判断: -### 我能帮助的任务 +1. 当前 C++/Python 代码和测试:`include/`、`src/`、`test/`、`sage_flow/`。 +2. 当前配置:`config/*.toml`、`CMakeLists.txt`、`pyproject.toml`。 +3. 最近的测试输出、benchmark 输出和真实实验 summary。 +4. `docs/`、论文 PDF、issue/plan/README:仅作为辅助,不作为已实现事实。 -- ✅ C++20 代码开发(Operator、Index、State 等核心组件) -- ✅ CMake 构建系统配置与调试 -- ✅ Google Test 单元测试和集成测试编写 -- ✅ Join 算法实现与优化(BruteForce, IVF, HNSW) -- ✅ 并发控制与线程安全代码审查 -- ✅ Python bindings (pybind11) 开发 -- ✅ 性能分析与优化建议 -- ✅ 代码审查与 clang-tidy 合规检查 -- ✅ GitHub PR/Issue 管理与代码审查 +如果文档与代码冲突,先指出冲突,再基于代码制定修改方案。 -### 我不会做的事情 +## 核心架构 -- ❌ 修改不属于 SageFlow 项目的代码 -- ❌ 跳过必要的测试验证 -- ❌ 违反项目命名规范和代码风格 -- ❌ 直接访问 Index 而不通过 ConcurrencyManager +### 流处理路径 ---- +1.

`JoinAlgorithm`、`PartitionStrategy`、`WindowStateType` 和 `IndexStrategy`,但稳定性不同: -```cpp -class RuntimeContext { - size_t getSubtaskIndex() const; // 当前并行实例 (0-based) - size_t getParallelism() const; // 总并行度 - std::string getTaskName() const; // "Task[2/8]" 格式 -}; -``` +- Shared Index Join 主路径:`ROUND_ROBIN + SHARED + SHARED`,适合共享状态/共享索引路径。 +- ClusteredJoin 主路径:`CENTROID + PARTITIONED + PARTITIONED`,要求 `num_partitions == parallelism` 时更容易保证分区语义,使用 `CentroidPartitioner` 的 cold-start 与 multicast 机制。 +- VSJoin 研究路径:当前代码包含 VSJoin 双层索引、local/global index、后台 rebuild、路由调试和 assignment/load-monitor 组件,但仍有实现与文档/测试注释不一致之处;修改前必须阅读 VSJoin 专项 agent。 +- LSH、S3J、TwoTier/PartitionedVector 等路径可能是实验性或局部可用,不能默认端到端稳定。 -#### WindowState +## 并发正确性原则 -```cpp -class WindowState { -

`RuntimeContext` 获取 `subtask_index` 和 `parallelism`,不要使用全局线程 id 推断分区。 +- 分区策略应优先保证 partition-local 状态和索引隔离,避免跨分区共享写锁。 +- 共享策略在多线程下必须明确锁边界;修改 IQ/QIQ 或 `join_rw_mutex_` 相关逻辑时必须证明不会丢召回。 +- 窗口过期必须使用安全时间戳策略,考虑乱序、双侧推进、分区级 `max_seen_timestamp` 和 eviction buffer。 +- 多播会制造重复状态和重复候选;输出侧必须有明确 owner-computes 或 UID 去重策略。 +- 后台线程必须支持安全启动、一次初始化、停止和析构 join。 +- 原子读写、双缓冲映射、shared pointer 快照等生命周期设计必须有对应并发测试。 -#### ConcurrencyManager (索引管理) +## 性能优化原则 -```cpp -class ConcurrencyManager { - int create_index(name, IndexType, dimension, params); // 标准索引 - int register_index(name, std::shared_ptr index); // 自定义索引 - bool insert(index_id, std::unique_ptr record); - std::vector> query(index_id, record, k); -}; -``` +- 热路径优先减少锁等待、重复拷贝、跨分区共享写、无界扫描和频繁索引删除。 +- 使用 `reserve()`、`emplace_back()`、`std::move()`,避免在候选循环里不必要分配。 +- 指标必须拆开:candidate fetch、similarity verification、join function、window insert/evict、index insert/delete、lock wait、apply total。 +- 优化吞吐时同时报告 recall、duplicates、p50/p99 latency、sync overhead;只给 throughput 是不完整结论。 +- 对高并行优化要验证 p=1、p=2、p=4、p=8 及更高并行下的正确性变化,不得声称线性扩展。 ---- +## 构建与测试 -## 构建与测试命令 +常用命令: ```bash -# 配置 cmake -B build

`--methods`、`--gtest-filter`、`--parallelism`、`--data-sizes` 筛选/覆盖 test case,生成 `/run_/filtered_config.toml`,再通过环境变量调用 `build/bin/test_join_baseline_integration`。 ---- +常用方式: -## 开发规范 +```bash +python3 scripts/run_integration_test.py --methods bruteforce --parallelism 1 2 --data-sizes 500 --build +python3 scripts/run_integration_test.py --methods ivf hdr_tree --parallelism 1 4 --data-sizes 1000 +python3 scripts/run_integration_test.py --gtest-filter '*clustered_k_sweep_k1*:*clustered_k_sweep_k4*' --parallelism 4 -c config/integration_test_cases.toml +``` -### 日志使用 +注意事项: -```cpp -SAGEFLOW_LOG_DEBUG("TAG", "Message with {} args", value); -SAGEFLOW_LOG_INFO("TAG", "Informational message"); -SAGEFLOW_LOG_WARN("TAG", "Warning: {}", issue); -SAGEFLOW_LOG_ERROR("TAG", "Error occurred: {}", error_msg); -``` +- 不要默认 `--methods all`;每次只跑当前最关注的 1-3 个方法或少量 gtest pattern。 +- `--parallelism` 和 `--data-sizes` 会覆盖 TOML 内对应字段,可用于快速缩小测试矩阵。 +- 脚本会设置 `SAGEFLOW_TEST_CONFIG_PATH` 指向 filtered config,并设置 `SAGEFLOW_TEST_OUTPUT_DIR` 隔离输出目录。 +- 日志在 `/logs/runner.log` 和 `/logs/binary.log`;CSV/JSON 汇总由测试二进制写入 run dir 或 fallback 到 `test/result/integration`。 +- ClusteredJoin/分区 Join 需要特别检查 `num_partitions == parallelism`;脚本注释说明部分路径会在运行时修正,但配置和报告仍应显式记录。 -### 测试工具 (test/test_utils/) +### 性能测试 -- `TestDataGenerator`: 生成具有可控相似度属性的合成向量数据集 -- `JoinTestHelper`: 简化 Join 测试的左/右流创建 -- `BaselineJoinChecker`: 计算 Join 操作的 ground truth +`build/bin/test_join_datasource_modes` 是性能/数据源模式测试。它不是通过 `run_integration_test.py` 驱动,而是在 C++ 中读取 `config/perf_join_datasource_modes.toml` 的 `[[performance_test]]`,展开 `methods × sizes × parallelism × window_time_ms` 形成参数化测试。 -### 性能优化建议 +常用方式: -- 对大对象使用 `std::move` (尤其是 `VectorRecord`) -- 优先使用 `emplace_back` 而非 `push_back` -- 已知大小时使用 `reserve()` -- 热路径考虑缓存局部性 -- 尽可能使用无锁结构 (参见 `concurrency/`) +```bash +cmake --build build --target test_join_datasource_modes -j $(sysctl -n hw.ncpu) +./build/bin/test_join_datasource_modes --gtest_filter='*DataSourceModePerformance*' +./build/bin/test_join_datasource_modes --gtest_filter='*bruteforce_1000_p1*:*ivf_1000_p4*' +``` ---- +性能测试注意事项: -## 关键约束 (必须遵守) +- 选择方法和参数主要通过 `config/perf_join_datasource_modes.toml` 的 `methods`、`sizes`、`parallelism`、`window_time_ms`、`mode`、`data_source`、`split_mode`、`similarity_mode`、`similarity_alpha` 控制。 +- 只保留当前关注的少量 `[[performance_test]]` block,或把 `methods` 缩到少数方法;不要保留大矩阵后直接运行。 +- `mode=generate_direct_use` 排除文件 IO,适合算法 hot path;`direct_load` 适合 SIFT 等真实数据;`generate_save_load` 会生成并落盘数据。 +- `split_mode=duplicate|half_split|interleaved` 会改变左右流构造和 ground truth,比较结果时必须一起记录。 +- 测试会计算 brute-force ground truth、等待输入 drain 30s、再等待输出稳定最多 5s;超时通常表示配置/并发路径异常,不要简单拉长等待掩盖问题。 +- 明细 JSON 写到 `test/result/datasource_modes/`,汇总 TSV 写到 `test/result/datasource_modes_report.tsv`,每次复现实验前应确认是否需要清理旧结果。 +- 指标 TSV 另写入 `build/metrics/join_datasource_modes_*.tsv`,用于 JoinMetrics breakdown。 -1. **RuntimeContext**: 在操作符方法中始终传递和使用 `RuntimeContext` 获取线程标识 -2. **Index 线程安全**: 始终通过 `ConcurrencyManager` 操作索引,永不直接访问 `Index` -3. **索引创建**: 标准类型用 `create_index()`,自定义类型用 `register_index()` -4. **状态管理**: 使用 `WindowState` 抽象;访问前检查 `isShared()` -5. **clang-tidy**: 所有新代码必须通过 clang-tidy 检查 -6. **Join 集成测试**: 修改 Join 相关代码后,**必须**运行(不用全量测试,跑关键用例): - ```bash - ./build/bin/test_join_datasource_modes - ``` +### 测试选择原则 ---- +- 正确性/配置链路优先跑 `scripts/run_integration_test.py`,因为它覆盖 TOML 过滤、pipeline 构建、ground truth、recall/precision 和报告链路。 +- 性能/数据源/参数扫描优先跑 `test_join_datasource_modes`,但必须先裁剪 TOML 矩阵。 +- 修改 Join hot path 后,先用小规模 `bruteforce` 或目标方法验证,再扩大到对照方法;不要一开始跑所有算法、所有并行度。 +- 报告结果时同时写明入口、配置文件、effective filtered config、方法列表、sizes、parallelism、数据源模式和输出目录。 -## 输入/输出规范 +## 日志与诊断 -### 理想输入 +使用统一日志宏: --

Local index。 +- 当前 factory 硬编码 Global 为 IVF、Local 为 BruteForce;`vsjoin_local_index_type` 和 `vsjoin_global_index_type` 虽已解析,但不能假设已完全生效。 +- `VSJoinMethod::ExecuteEager()` 查询 Local index 与 Global index,合并 UID、去重,再从 `WindowState` snapshot 解析为候选记录。 +- `JoinOperator::initializeWithStrategyConfig()` 下发 global/local index id,创建 `VSJoinPartitionAssignment` 和 `VSJoinLoadMonitor`。 +- `JoinOperator::apply()` 中 VSJoin 分支会把记录多播到目标 subtask,并在 `updateSideWithState()` 中只插入对应 subtask 的 Local index。 +- `globalIndexRebuildLoop()` 后台线程周期性从 WindowState snapshot 收集有效记录、UID 去重、重建 IVF global index,并通过 `ConcurrencyManager::replace_index_by_id()` 替换。 +- `VSJoinPartitionAssignment` 使用双缓冲 mapping table 和 atomic pointer,读路径无锁,写路径批量更新。 +- `VSJoinLoadMonitor` 记录 subtask 负载、延迟和 backlog,当前更多是基础组件而非完整控制器。 + +当前代码中的重要边界: + +- `getPreferredPartitioner()` 对 VSJoin 当前临时复用 `CentroidPartitioner` 以获得 multicast 能力,注释说明待实现 LSH multicast 后再切回。 +- `apply()` 中 Task08 logical partition routing + assignment table 目前被注释为临时禁用,执行上退化为 partitioner 输出 physical partitions 到 target subtask。 +- `JoinStrategyConfig::validate()` 要求 VSJoin 使用 LSH + partitioned-family WindowState + partitioned

`num_partitions`,重点看 recall、duplicates、load imbalance。 +- VSJoin 消融:只跑 `vsjoin` 相关配置变体,一次只改一个参数,不要同时扫 size、parallelism、routing 和 rebuild。 + +## 设计不变量 + +### 正确性 + +- 每个输出 pair 必须满足时间窗口条件和相似度阈值;approximate index 只能影响候选召回,不能跳过最终 verification。 +- 多播路径必须处理重复 UID 和重复输出;Local/Global candidate merge 必须去重。 +- WindowState snapshot 的生命周期必须覆盖 rebuild/query 使用周期,不能返回悬空指针。 +- 过期策略必须考虑乱序输入和多线程处理,不能因单个 subtask 时间推进误删其他 subtask 需要的记录。 +- IQ/QIQ 策略修改必须以 recall 测试证明;已知 QIQ 在 shared+multi-thread 下可能丢召回,不能默认启用。 +- 后台 rebuild 只能替换可替换索引;替换前后的 query 不应 crash,不应泄露旧 index 生命周期。 + +### 并发 + +- Hot-path 路由读操作必须避免全局锁;mapping table 读路径保持 atomic pointer/acquire-load 模式。 +- 写路径可以批量加锁,但必须低频、可观测、可回滚或可禁用。 +- Local index ownership 必须与 subtask/partition 绑定;不要让多个 subtask 并发写同一个 local index,除非明确引入同步和测试。 +- Global index 应被视作共享只读/周期性替换结构;不要在 hot path 中频繁重建或全局写锁保护查询。 +- 线程生命周期必须由 `JoinOperator` 析构安全停止;禁止 detached background worker。 + +### 性能 + +- 优化目标不是单一 throughput,而是 effective throughput = throughput * recall。 +- 每次优化必须同时考虑 candidate_fetch、window_insert、index_insert、similarity、join_function、lock_wait、apply_total。 +- 多播预算、rebuild interval、batch delete threshold、eviction

时必须证明 snapshot 生命周期、UID 去重和 replace 语义安全。 + +### VSJoinMethod + +- Local index 查询必须使用与 query slot 相反侧的 local index。 +- Global index 查询必须使用与 query slot 相反侧的 global index。 +- UID merge 后必须去重,再从对应 WindowState snapshot resolve。 +- 不要把 index 返回的 shared pointer 直接暴露给会跨锁/跨线程持有的调用方,除非生命周期可证明。 + +### PartitionAssignment 和 LoadMonitor + +- `getPhysicalSubtask()` 是高频读路径,保持无锁或近似无锁。 +- `updateMapping()` 是低频控制路径,允许加锁但必须批量更新并原子发布。 +- `LoadMonitor` 的指标含义必须清晰:record_count、avg_latency_ms、queue_backlog 不可混用。 +- 引入 rebalance controller 时必须防止 oscillation,设置 hysteresis/cooldown 并测试。 + +### Config 和 Factory + +- 新增配置必须加入 parse、validate、summary、factory 使用和测试。 +- 如果配置字段尚未生效,文档必须写明“已解析但未接入执行路径”。 +- 不要让 validator、factory、operator 三处规则互相矛盾;如需临时兼容测试,要在注释和 agent 文档里标注。 + +## 论文一致性规则 + +- 论文中 P1-P4 是研究
