的映射格式，也不必修改策略或提供券商凭据，就能通过“内置适配器优先、确定性检测、可选 AI 候选映射、人工补齐身份、只读预览、显式导入”的流程完成接入。 + +v0.3 的核心交付不是“支持所有券商”，而是一套可扩展、可审计、适合社区贡献的接入机制。内置适配器解决已知格式；AI 只处理长尾陌生格式；严格 profile 和 preview 仍是唯一写库门槛。 + +## 问题重新定义 + +v0.2 已经证明，QuantCockpit 可以在不改策略代码的情况下读取本地仓位文件并完成敞口分析，但首次接入仍要求用户手写 `PositionMappingProfile`。这对实现者可接受，对普通量化用户仍然过重。 + +用户原先的判断“实盘和模拟盘日志没有统一标准”只对了一半： + +- 语义互操作层存在标准，例如 [FDC3 Position](https://fdc3.finos.org/docs/context/ref/Position) 和 [FDC3 Portfolio](https://fdc3.finos.org/docs/context/ref/Portfolio)。 +- 平台层存在统一抽象，例如 [CCXT 的 unified positions](https://github.com/ccxt/ccxt/wiki/Manual#positions)，但它只覆盖合约仓位，且实际数据仍受交易所能力影响。 +- 券商层存在可配置报表，例如 [IBKR Flex Web Service](https://www.interactivebrokers.com/campus/ibkr-api-page/flex-web-service/)，但字段取决于用户创建的 Flex Query，并不是一个固定 CSV schema。 +- 通用日志采集、交易消息、券商报表、组合语义和风险分析属于不同层级；没有一个标准同时给出 QuantCockpit 所需的策略身份、环境、来源、组合、快照时点和可分析仓位度量。 + +所以正确问题不是“有没有唯一标准”，而是：如何把现有标准和常见导出稳定地桥接到 QuantCockpit 的严格事件契约，并让未知格式的适配成本足够低。 + +## 最小全局认识 + +仓位接入领域至少分为五层，v0.3 只负责其中的语义桥接层： + +1. **采集与传输**：文件、对象存储、OpenTelemetry、消息队列。解决“数据怎么到达”，不定义仓位语义。 +2. **交易互操作**：FIX、券商 API、交易所 API。解决订单、成交和部分仓位交换，但通常依赖凭据、会话和平台约束。 +3. **语义上下文**：FDC3、机构内部 canonical model。解决字段意义和对象关系，但不一定包含运营身份与完整风险度量。 +4. **报表与导出**：IBKR Flex、平台 CSV、策略日志。最适合零侵入读取，但格式异构。 +5. **分析与观测**：QuantCockpit。把可信快照转成覆盖率、集中度、敞口和报告，并保留证据链。 + +v0.3 不取代前四层，也不把 QuantCockpit 变成券商连接器平台。它提供第 4 层到第 5 层之间的声明式适配协议。 + +## 设计原则 + +1. **确定性优先**：已知格式由版本化适配器处理；相同文件和 catalog 必须产生相同排名、profile 和预览。 +2. **AI 只提议**：AI 输出是不可信候选稿，不得执行代码、填充不可推断的身份、直接写库或决定风险结果。 +3. **身份不猜测**：`strategy_id`、`environment`、`source`、`portfolio_id` 和真实 `snapshot_time` 缺失时由用户显式提供。 +4. **只读优先**：detect、draft、finalize 和 preview 均不创建数据库、不修改输入文件、不访问券商。 +5. **数据最小化**：AI 默认只能看到结构描述；发送样本值必须通过单独的显式同意参数。 +6. **数据包而非插件代码**：Adapter Pack 只包含严格 JSON、文档和合成夹具，不加载 Python、Shell、模板或动态入口点。 +7. **诚实降级**：来源只有 quantity 时就只提供身份可见能力，不把合约数量伪装成市场价值或因子暴露。 +8. **核心离线可用**：不安装 AI 可选依赖、没有 API key、没有网络时，内置适配器、检测、预览和导入仍完整可用。 + +## 范围 + +### v0.3.0 包含 + +- 版本化 Adapter Pack 契约、内置 catalog、校验器和稳定摘要。 +- 对 CSV、JSON、JSONL 的受限结构探测和确定性适配器评分。 +- `PositionProfileDraft`，用于表达尚未补齐身份的安全候选映射。 +- draft 补齐身份后生成严格 `PositionMappingProfile 1.1` 的 finalize 流程。 +- JSON/JSONL 数字直接解析为 Decimal，避免 CCXT 等 JSON 数值先经过二进制 float。 +- FDC3 Portfolio 2.2 ticker identifier 变体和 CCXT unified contract position 首批稳定适配器。 +- IBKR Flex Open Positions 的受控 recipe；只有取得可公开复现的字段依据后才进入自动检测 catalog。 +- provider-neutral 的 Mapping Assistant 接口和一个可选 AI provider。 +- 默认仅上传字段名、结构路径、推断类型和统计摘要；样本值必须显式授权。 +- 统一 `quantcockpit` CLI，并兼容现有 `scripts/import_positions.py`。 +- 合成夹具、适配器贡献规范、两分钟演示和离线端到端测试。 + +### v0.3.0 不包含 + +- 保存券商或交易所凭据、直接调用账户 API、主动轮询远程账户。 +- 文件监听、守护进程、消息队列或实时流处理。 +- 允许 Adapter Pack 携带或执行代码。 +- 自动从成交重建仓位，或判断上游报表是否经济上正确。 +- MT5 内置适配器；在缺少可再分发、跨 locale、跨 broker 的公开样本前，硬编码列名会制造虚假兼容性。 +- CCXT spot balance；首个 CCXT 适配器只声明 contract positions 能力。 +- 自动价格、汇率、合约乘数、Greeks、因子 Beta 或 VaR。 +- Web 上传和写入 API；v0.3 保持本地 CLI 接入，前端继续展示导入后的结果。 +- 定时报告、邮件、SMTP、重试队列和密钥管理。这些属于独立的交付信任边界，计划放入 v0.4。 +- AI 自动导入、后台静默调用或默认上传原始行。 + +## 用户路径 + +### 已知格式：两条命令看到结果 + +```bash +uv run quantcockpit positions detect ./positions.json + +uv run quantcockpit positions preview ./positions.json \ + --adapter auto \ + --set strategy_id=trend-following \ + --set environment=paper \ + --set source=ccxt-export \ + --set portfolio_id=paper-book-a \ + --set snapshot_time=2026-07-20T16:00:00Z \ + --save-profile ./ccxt-position-profile.json +``` + +`--adapter auto` 只接受唯一且达到推荐门槛的稳定适配器。没有唯一结果时命令失败并展示候选及原因，不静默挑选。 + +用户确认预览后显式导入： + +```bash +uv run quantcockpit positions import ./positions.json \ + --profile ./ccxt-position-profile.json +``` + +### 未知格式：AI 生成候选稿 + +```bash +uv run quantcockpit positions draft ./unknown.csv \ + --ai openai \ + --output ./unknown-profile-draft.json + +uv run quantcockpit

\ + --set snapshot_time=2026-07-20T16:00:00Z \ + --save-profile ./unknown-position-profile.json +``` + +默认 AI 请求不包含任何样本值。只有用户同时提供 `--include-samples --allow-data-upload` 时，才发送经过本地脱敏的最多 3 条样本。两个参数缺一即拒绝。 + +### 保留兼容性 + +现有命令继续有效： + +```bash +uv run scripts/import_positions.py \ + --input ./positions.csv \ + --profile ./position-profile.json \ + --preview +``` + +旧脚本改为调用同一 application service，不保留第二套导入逻辑。现有 profile 1.0 继续可用。 + +## 总体架构 + +```mermaid +flowchart LR + A["本地 CSV / JSON / JSONL"] --> B["受限结构探测器"] + C["内置与显式自定义 Adapter Catalog"] --> D["确定性评分器"] + B --> D + D

Pack 契约 + +### 文件布局 + +内置 pack 作为 Python package data 发布，避免源码运行正常、wheel 安装后资源丢失： + +```text +src/quantcockpit/adapters/builtin/ +├── fdc3-portfolio-ticker-2-2/ +│ ├── adapter.json +│ ├── profile-draft.json +│ ├── README.md +│ └── fixtures/ +│ ├── positive.json +│ └── negative.json +└── ccxt-contract-positions-1/ + └── ... +``` + +社区 pack 使用同一结构，但不会从任意环境目录自动发现。用户必须通过 `--adapter-dir ` 显式加入；CLI 输出中始终标记来源是 `builtin` 还是 `custom`。 + +### `adapter.json` + +```json +{ + "adapter_api_version": "1.0", + "id": "fdc3-portfolio-ticker-2-2", + "display_name": "FDC3 Portfolio 2.2 (ticker identifier)", + "status": "stable", + "source_family": "fdc3", + "source_schema_version": "2.2", + "documentation_url": "https://fdc3.finos.org/docs/context/ref/Portfolio", + "input": { + "format":

"negative": ["fixtures/negative.json"] + } +} +``` + +正式 manifest 必须满足以下约束： + +- `adapter_api_version` 当前只接受 `1.0`。 +- `id` 使用小写 ASCII、数字和连字符，最大 64 字符；catalog 内唯一。 +- `status` 只有 `stable` 或 `experimental`。 +- URL 只用于文档展示，检测和导入过程不访问它。 +- `profile_draft` 必须是 pack 根目录内的普通文件，拒绝绝对路径、`..` 和符号链接逃逸。 +- manifest、draft 和每个夹具不超过 1 MiB；单个 pack 最多 32 个普通文件、总大小不超过 10 MiB。 +- `fixtures` 必须同时列出至少一个 positive 和一个 negative 合成夹具；摘要和 contract test 只读取清单内文件。 +- `capabilities` 只能声明真正映射到 canonical event 的字段，不能把可推断但未验证的值写入 profile。 + +### 检测谓词 + +检测采用有限结构谓词，不使用正则、表达式或代码。每个谓词包含： + +- `scope`：`root`、`record` 或 `position`。 +- `path`：RFC 6901 JSON Pointer；CSV record 使用精确列名。 +- `kind`：`present`、`json_type`、`const` 或 `enum`。 +- `expected`：严格 JSON 值，或 `object`、`array`、`string`、`number`、`integer`、`boolean`、`null` 之一。 +- `weight`：仅 weighted 谓词需要，正整数。 + +`position` scope 相对 draft 的 `positions_path`；`record` scope 相对 CSV 行、JSON 顶层数组元素或 JSONL 记录。检测器只检查有界样本，不遍历无限深度结构。 + +每个 pack： + +- `required` 必须全部命中，否则不具备候选资格。 +- `forbidden` 任一命中即排除。 +- `weighted` 的权重总和必须恰好为 100。 +- 分数为命中权重之和，不根据 catalog 顺序或文件名加分。 + +### 评分与歧义 + +```text +recommended：最高分 >= 80，status=stable，且领先第二名至少 10 分 +ambiguous：最高分 >= 80，但领先不足 10 分 +candidate：最高分为 50–79 +no_match：没有合格候选或最高分 < 50 +``` + +只有 `recommended` 可被 `--adapter auto` 使用。`experimental` pack 永远需要显式 `--adapter --allow-experimental`。同分结果按 adapter id 排序以保证输出稳定，但不因此自动选择。 + +每个结果必须输出：分数、命中的必要/加权谓词、缺失项、冲突项、pack 状态和摘要。错误输出不回显原始值。 + +### Pack 稳定摘要 + +Adapter Pack 的证据摘要由 `adapter.json`、`profile-draft.json` 和清单中列出的 fixture SHA-256 组成，再对规范化清单计算 SHA-256： + +```text +adapter:sha256: +``` + +README 不参与摘要，避免文案修改改变映射身份。生成的 profile 1.1 记录 adapter id 和 pack hash，使同名 adapter 的不同版本可追溯。 + +## Profile Draft 与最终 Profile + +### 为什么不能让 adapter 直接产出 v0.2 profile + +v0.2 的 `PositionMappingProfile` 要求五个身份字段完整，但 FDC3、CCXT 和多数报表不会同时提供策略身份、环境和真实快照时点。给这些字段设“合理默认值”会造成跨账户或实盘/模拟盘错误合并。 + +因此 v0.3 引入独立的 `PositionProfileDraft`：它允许缺少身份字段，但不能用于 preview 或 import。只有 finalize 后通过现有严格校验的 `PositionMappingProfile` 才能进入导入器。 + +### Draft 契约 + +```json +{ + "draft_version": "1.0", + "name": "ccxt-contract-positions", + "format": "json", + "layout": "tabular_snapshot", + "snapshot_scope": "whole_file", + "fields": {}, + "position_fields": { + "instrument_id": {"path": "/symbol", "transforms": ["trim"]}, + "instrument_id_type": {"literal": "contract"}, + "side": {"path": "/side", "transforms": ["trim", "lowercase"]}, + "quantity": {"path": "/contracts", "transforms": ["decimal"]} + }, + "unresolved_fields": [ + "strategy_id", + "environment", + "source", + "portfolio_id", + "snapshot_time" + ], + "provenance": { + "origin": "adapter", + "adapter_id": "ccxt-contract-positions-1", + "adapter_pack_hash": "sha256:..." + }, + "diagnostics": [] +} +``` + +Draft 仍然 `extra="forbid"`，字段绑定和转换 allowlist 与正式 profile 相同。它不是宽松的任意 JSON 容器。 + +### Finalize 规则 + +- `--set key=value` 只允许补齐 metadata field，不允许覆盖 adapter 已绑定的 position field。 +- 已存在绑定默认不能覆盖；确需覆盖时使用显式 `--replace key=value`，并在 provenance 中记录字段名，不记录敏感值。 +- `snapshot_time` 必须是带时区 RFC 3339 或使用正式 binding 的本地时间配置；不能用文件修改时间代替。 +- `recorded_at` 可以继续使用 v0.2 的 import observed time 规则。 +- 输出文件已存在时默认拒绝；只有显式 `--force` 才覆盖。 +- finalize 生成 `PositionMappingProfile 1.1`。profile 1.1 只比 1.0 新增严格 `provenance`；1.0 继续兼容。 +- profile hash 继续覆盖完整 profile，因此 adapter/assistant provenance 也进入审计摘要。 + +`provenance.origin` 为 `adapter`、`assistant` 或 `manual`。assistant provenance 记录 provider、model、assistant contract version 和本地结构摘要，不保存 prompt 原文、API key 或样本值。 + +## 受限结构探测 + +结构探测器复用 v0.2 的文件安全边界：普通文件、允许扩展名、100 MiB 文件上限、UTF-8、1 MiB 记录上限。额外限制： + +- 最多检查 200 条记录、每个数组最多检查前 50 个元素、嵌套深度最多 20、结构路径最多 10,000 个；触及上限时返回明确诊断而不是静默截断后给高置信推荐。 +- CSV 读取 header 和有界行；JSON 文档仍受整体 100 MiB 限制；JSONL 有界读取。 +- 输出仅包含字段名/JSON Pointer、推断标量类型、出现比例、空值比例和结构冲突。 +- 字符串长度、具体值、绝对路径和文件名默认不进入结构摘要。 +- detect 不创建 profile 文件、不创建数据库、不调用网络。 + +探测器对同一输入字节和 catalog 内容必须生成字节级稳定的 JSON 输出；时间戳、随机数和机器路径不得参与结果。 + +## Decimal JSON 输入 + +当前 v0.2 使用标准 `json.loads`，JSON 小数会先变成 Python float，然后被仓位 Decimal 校验正确拒绝。这保护了分析精度，却会让 CCXT 这类正常 JSON 导出无法接入。 + +v0.3 修改 JSON/JSONL 来源解析： + +- 使用 `json.loads(..., parse_float=Decimal)`，JSON integer 保持 `int`。 +- 只接受有限 Decimal；拒绝 NaN、Infinity 和非标准 JSON 常量。 +- JSON 科学计数法先按十进制语义精确展开，再执行 30 位有效数字和 18 位小数上限。 +- 规范事件仍输出不带指数的定点十进制字符串；直接 profile literal 的指数形式规则不放宽。 +- 任何路径都不得先转为 binary float 再构造 Decimal。 + +现有 `raw_json` 是结构化证据重编码，而不是原文件逐字节副本。为让 Decimal 可安全重编码，来源 JSON 数字在 `raw_json` 中使用不带指数的 JSON 字符串表示；行号和 source reference 继续定位本地原文件。文档必须明确这一语义，不能宣称 byte-for-byte 保存。 + +## 首批适配器 + +### FDC3 Portfolio 2.2 identifier variants：stable + +- 识别 `type = "fdc3.portfolio"` 和 `positions` 数组结构。 +- FDC3 的 `instrument.id` 是由应用约定键名的对象，并没有一个强制通用 identifier。首版因此发布明确变体，例如 `fdc3-portfolio-ticker-2-2`；它只在 `/instrument/id/ticker` 确实存在时推荐。 +- position 映射对应的具体 identifier 与 `holding`。后续 ISIN、FIGI 等变体复用同一契约，但各自拥有独立 adapter id、夹具和 detection。 +- `holding` 只映射为 quantity，不假设价格、权重或市场价值。 +- 只有 generic FDC3 结构、但没有已支持 identifier key 时，detector 只说明“语义标准已识别、identifier 未适配”，不会生成不可用 profile。 +- 缺少 venue 时不猜测。 +- `strategy_id`、`environment`、`source`、`portfolio_id`、`snapshot_time` 缺失时全部要求用户提供。 + +### CCXT Unified Contract Positions：stable + +- 只处理 unified contract position 数组，不宣称支持 spot balances。 +- 映射 `symbol`、`side`、`contracts`；`instrument_id_type = contract`。 +- `contracts` 作为 quantity。第一版不把 `notional` 自动映射为基础币种价值，因为其结算币种和跨交易所一致性不能只由统一字段安全确认。 +- 每条 position 的 `timestamp` 不自动当作整个导出文件的 snapshot time；用户必须提供统一快照时点，或后续 adapter 获得可验证的文档级时点。 +- adapter capability 因此可能只有 Level 0；预览要明确告诉用户还缺哪种分析基础。 + +### IBKR Flex Open Positions Recipe：experimental gate + +IBKR Flex 查询是用户可配置模板，不存在一个可诚实声称覆盖所有用户的固定 CSV。v0.3 提供“如何创建兼容 Flex Query”的字段 recipe 和合成 fixture，但自动检测 pack 必须满足发布门槛： + +1. 每个列名和含义都能追溯到 IBKR 官方字段资料或可合法再分发的公开样本。 +2. fixture 完全合成，不包含账号、真实持仓或客户数据。 +3. pack 只匹配该 recipe 生成的导出，不使用“IBKR CSV”这种过宽名称。 +4. 未满足门槛时只发布文档 recipe，不进入 catalog；满足后仍先标记 `experimental`，必须显式选择。 + +这不是延期借口，而是防止作品集通过猜字段制造兼容性假象。MT5 采用同样证据门槛，留待后续版本。 + +## Mapping Assistant + +### 接口 + +核心定义 provider-neutral 协议： + +```text +MappingAssistant.propose( + structure: SourceStructure, + adapter_candidates: tuple[AdapterCandidate, ...], + samples: RedactedSamples | None, +) -> PositionProfileDraft +``` + +核心包不依赖云 SDK。首个 OpenAI provider 通过 `ai-openai` 可选依赖安装，并实现严格 structured output；测试使用本地 fake provider，不发网络请求、不需要 API key。provider 必须输出最终采用的 model，CLI 不得在用户不知情的情况下切换模型。 + +### 默认请求内容 + +- 输入格式、layout 候选和 root kind。 +- 字段名或 JSON Pointer。 +- 每个字段推断的标量类型集合。 +- 出现比例、null 比例和结构冲突。 +- 确定性 adapter 的候选分数与原因。 +- PositionProfileDraft JSON Schema。 + +默认不包含：字段值、文件名、绝对路径、真实账号、环境变量、数据库内容或其他文件。 + +### 显式样本授权 + +只有 `--include-samples --allow-data-upload` 同时存在时才生成样本载荷。载荷： + +- 最多 3 条记录、最多 50 个字段、每个字符串最多 128 字符。 +- 字段名匹配 `account`、`token`、`secret`、`password`、`key`、`email` 等敏感模式时，值替换为 ``。 +- 高熵长字符串、邮箱、IP、绝对路径和疑似账号标识按本地确定性规则脱敏。 +- CLI 在发送前输出字段数量、记录数量、provider 和 model，但不打印样本值。 + +用户必须能够通过 `--export-ai-payload ` 在不发送的情况下审阅精确 payload。导出的 payload 视为敏感文件，默认权限设为当前用户可读写，已存在文件不覆盖。 + +`--export-ai-payload` 是 dry-run：写出 payload 后立即退出，不调用 provider。用户审阅后需重新运行不带该参数的命令才会发送。脱敏是降低风险的防线而不是匿名化保证；只要用户不能接受字段名或剩余样本离开本机，就应停留在 deterministic adapter 和手工 draft 流程。 + +### 不可信输出边界 + +AI 输出必须依次通过： + +1. provider structured-output schema。 +2. `PositionProfileDraft` 的 Pydantic 严格校验。 +3. 路径确实存在于本地结构摘要的检查。 +4. transform allowlist 检查。 +5. 身份字段不得由 AI 填固定值的检查。 +6. finalize 的正式 profile 校验。 +7. preview 的真实输入验证。 + +任一步失败都只保存安全诊断，不产生 profile、不写数据库。AI 不能生成表达式、代码、正则、SQL、Shell、网络 URL 或新 transform。 + +### 可复现性 + +AI 本身不具备字节级确定性，因此： + +- 相同 AI 请求不承诺相同 draft。 +- 一旦用户保存并 finalize，严格 profile 和 profile hash 就成为后续导入的唯一依据。 +- 导入路径不再次调用 AI。 +- provenance 记录 provider/model/assistant contract version 和输入结构 hash，以便解释候选稿来源。 +- CI 不调用真实模型；所有上线门槛基于 deterministic core 和固定 fake response。 + +## CLI 契约 + +在 `pyproject.toml` 增加： + +```toml +[project.scripts] +quantcockpit = "quantcockpit.cli:main" +``` + +使用 Python 标准库 `argparse`，不为 CLI 引入框架依赖。命令： + +```text +quantcockpit adapters list [--adapter-dir PATH] [--json] +quantcockpit adapters validate PATH [--json] +quantcockpit positions detect INPUT [--adapter-dir PATH] [--json]

--output PATH +quantcockpit positions preview INPUT (--profile PATH | --draft PATH | --adapter ID|auto) + [--set KEY=VALUE...] [--save-profile PATH] +quantcockpit positions import INPUT --profile PATH [--database PATH] +``` + +规则： + +- `--json` 输出是稳定 machine-readable schema；默认输出是面向人的中文摘要。 +- stdout 只输出结果；诊断和错误输出到 stderr；退出码稳定并写入文档。 +- `detect`、`draft`、`finalize`、`preview` 退出成功也不写数据库。 +- `import` 是唯一写库命令，并继续复用 v0.2 的事务、幂等和 revision 语义。 +- 自定义 pack 只能通过本次命令显式路径加载，不扫描 home、当前目录或环境变量隐含目录。 +- `--save-profile` 和 `--output` 使用原子写入；目标存在时默认失败。 + +新 CLI 的退出码固定为：`0` 成功、`2` 参数用法错误、`3` 无匹配或匹配歧义、`4` 来源/adapter/draft/profile 校验失败、`5` AI provider 或 AI 输出失败、`6` 正式导入或持久化失败。旧脚本为兼容现有自动化继续保留 `0/1` 语义。 + +## 错误语义 + +| 错误码 | 含义 | +| --- | --- | +| `adapter_pack_invalid` | manifest、draft、fixture 或目录边界不合法 |

Task 10: 文档、贡献流程与发布验证 + +**Files:** +- Create: `docs/adapters.md` +- Modify: `README.md` +- Modify: `CONTRIBUTING.md` +- Modify: `docs/architecture.md` +- Modify: `tests/test_scripts.py` +- Modify: `tests/test_adapter_catalog.py` +- Modify: `pyproject.toml` +- Modify: `src/quantcockpit/__init__.py` + +**Interfaces:** +- Produces: 两分钟公开演示、IBKR 受控 recipe、pack 贡献说明、wheel 资源验证和版本 `0.3.0`。 +- Consumes: 所有前序任务。 + +- [ ] **Step 1: 写 README 命令可执行测试** + +```python +def test_readme_adapter_detect_and_preview_commands_are_executable(tmp_path: Path) -> None: + readme = (ROOT / "README.md").read_text(encoding="utf-8") + detect = "uv run quantcockpit positions detect src/quantcockpit/adapters/builtin/ccxt-contract-positions-1/fixtures/positive.json --json" + assert detect in readme + assert subprocess.run(shlex.split(detect), cwd=ROOT, capture_output=True, text=True).returncode == 0 +``` + +preview 文档命令使用固定 synthetic identity、`paper` 和 2026-07-20 UTC 时点，测试把 `--save-profile` 输出重定向到 tmp path，避免污染仓库。 + +- [ ] **Step 2: 写 wheel 内置资源测试** + +```python +def test_built_wheel_contains_and_loads_builtin_adapters(tmp_path: Path) -> None: + subprocess.run(["uv", "build", "--wheel", "--out-dir", str(tmp_path)], cwd=ROOT, check=True) + wheel = next(tmp_path.glob("quantcockpit-0.3.0-*.whl")) + with zipfile.ZipFile(wheel) as archive: + names = set(archive.namelist()) + assert any("fdc3-portfolio-ticker-2-2/adapter.json" in name for name in names) + assert any("ccxt-contract-positions-1/adapter.json" in name for name in names) +``` + +- [ ] **Step 3: 更新 README 两分钟路径和局限** + +README 增加 detect、auto preview、save-profile、import 四条命令，说明 AI 默认不上传值、OpenAI extra 安装命令、`--export-ai-payload` dry-run。把局限中的 v0.2 改为 v0.3，明确 FDC3 只支持 ticker variant、CCXT 只支持 contract quantity、quantity-only 不计算价值集中度。 + +- [ ] **Step 4: 编写 `docs/adapters.md` 和 IBKR recipe** + +文档逐字段解释 manifest/draft/predicate/score/hash、positive/negative fixture 要求和安全目录限制。IBKR 部分只引用官方可验证事实：在 Client Portal 创建 Activity Flex Query、选择 Open Positions section、逐字段选择、输出 text/CSV 并包含 column headers；由于 query 字段可配置，v0.3 不提供“任意 IBKR CSV”自动 pack，用户先运行 detect，再使用 AI draft 或贡献一个带公开字段依据的 experimental recipe pack。 + +引用： + +- [IBKR Activity Flex Query](https://www.interactivebrokers.com/campus/glossary-terms/activity-flex-query/) +- [IBKR Client Portal

Positions](https://github.com/ccxt/ccxt/wiki/Manual#positions) + +- [ ] **Step 5: 更新贡献指南和架构** + +`CONTRIBUTING.md` 把“声明式映射示例”升级为 Adapter Pack contract：每个 pack 必须提供 manifest、draft、官方/公开语义链接、完全合成 positive/negative fixture、false-positive test 和能力限制。`docs/architecture.md` 增加 Source Inspection -> Catalog -> Draft -> Finalize -> Preview 数据流和 AI 七层信任边界；分析层保持不识别 adapter/provider。 + +- [ ] **Step 6: 更新版本并运行文档/资源测试** + +把 `pyproject.toml` 和 `src/quantcockpit/__init__.py` 版本改为 `0.3.0`。 + +Run: `uv run pytest tests/test_scripts.py tests/test_adapter_catalog.py tests/test_builtin_adapters.py -q` + +Expected: PASS；README 命令可执行，wheel 含两个 builtin packs。 + +- [ ] **Step 7: 运行完整离线门槛** + +Run: `make verify` + +Expected: 后端全部测试 PASS、前端 17 项及新增前端零项回归 PASS、Python/TypeScript 类型检查 PASS、Vite production build PASS。 + +- [ ] **Step 8: 验证可选 AI extra 但不发真实请求** + +Run: `uv run --extra ai-openai pytest tests/test_openai_provider.py tests/test_mapping_assistant.py tests/test_cli.py -q` + +Expected: PASS；只使用 fake client，没有网络和 API key。 + +- [ ] **Step 9: 做 fresh wheel smoke test** + +Run: + +```bash +release_tmp=$(mktemp -d) +uv build --wheel --out-dir "$release_tmp/dist" +uv venv "$release_tmp/venv" +uv pip install --python "$release_tmp/venv/bin/python" "$release_tmp"/dist/quantcockpit-0.3.0-*.whl +"$release_tmp/venv/bin/quantcockpit" adapters list --json +``` + +Expected: 输出包含两个 builtin adapter id；不安装 OpenAI SDK也能运行。 + +- [ ] **Step 10: 提交文档与版本** + +```bash +git add README.md CONTRIBUTING.md docs/adapters.md docs/architecture.md tests/test_scripts.py tests/test_adapter_catalog.py pyproject.toml src/quantcockpit/__init__.py +git commit -m "docs: publish v0.3 adapter onboarding" +``` + +### Task 11: 规范一致性与最终发布前审查 + +**Files:** +- Modify only files required by verified review findings. + +**Interfaces:** +- Produces: 干净 worktree、完整测试证据和可进入 ship 流程的 v0.3 分支。 +- Consumes: Tasks 1–10 的全部提交。 + +- [ ] **Step 1: 对设计规范逐条建立覆盖清单** + +Run: + +```bash +rg -n '^## |^### ' docs/superpowers/specs/2026-07-20-v0-3-adapter-assistant-design.md +rg -n 'adapter_|profile_|source_numeric_|ai_' src tests docs README.md CONTRIBUTING.md +``` + +Expected: 每个范围、错误码、安全边界、测试门槛都能定位到实现或明确的非目标文档；不存在实现声称超出两个 stable pack 的兼容性。 + +- [ ] **Step 2: 运行 secret、网络和任意代码边界审计** + +Run: + +```bash +rg -n 'eval\(|exec\(|subprocess|import_module|requests\.|httpx\.|urllib|API_KEY|sk-' src/quantcockpit/adapters src/quantcockpit/assistant.py src/quantcockpit/providers tests +``` + +Expected: Adapter core 无任意执行和网络；唯一远程调用位于 optional OpenAI provider；测试中的假 key 不进入 stdout/stderr 断言结果。 + +- [ ] **Step 3: 运行最终全量验证并保存摘要** + +Run: `make verify && uv run --extra ai-openai pytest tests/test_openai_provider.py tests/test_mapping_assistant.py -q && git status --short` + +Expected: 所有验证 PASS，`git status --short` 为空。 + +- [ ] **Step 4: 仅在审查产生修复时提交** + +```bash +git add -u -- src tests docs README.md CONTRIBUTING.md pyproject.toml uv.lock scripts +git commit -m "fix: close v0.3 adapter review findings" +``` + +若 Step 1–3 没有产生文件修改，则不创建空提交；记录最终通过的命令和测试数量，进入 `/ship` 流程。 From

+让用户在不连接券商、不修改策略代码、也不依赖 QuantCockpit 生产因子的前提下，把已有仓位快照与自有因子载荷导入本地系统，得到时点一致、口径明确、带覆盖率和证据链的当前因子暴露、风险状态与确定性报告。 + +v0.4 的核心交付是“持仓因子暴露观测层”，不是因子研究平台、行情数据平台或完整风险引擎。 + +## 问题重新定义 + +“计算当前组合是什么因子 beta 暴露”混合了三类不同问题： + +1. **因子收益**：Fama–French 等数据描述因子组合随时间的收益。 +2. **证券因子载荷或特征**：描述单个证券在某个模型、某个时点上的暴露。 +3. **组合当前暴露**：把当前仓位权重与证券载荷结合，得到组合对各因子的线性暴露。 + +QuantCockpit v0.4 只负责第三类，并把第二类作为用户提供的版本化输入。它不从第一类数据自动推导证券载荷，也不把任意归一化结果统一称为 beta。 + +这一区分直接决定产品可信度：缺少 NAV 或明确权重时，用市值除以 gross 得到的是“单位 gross 因子倾向”，而不是严格意义上的 portfolio beta。系统必须在 API、界面和报告中保留这一口径，风险策略也不能跨口径复用阈值。 + +## 最小全局认识 + +因子与组合风险生态至少分为五层： + +1. **因子收益库**：例如 [Kenneth French Data Library](https://mba.tuck.dartmouth.edu/pages/faculty/ken.french/data_library.html)，提供研究因子和组合收益。 +2. **股票级特征与学术复现**：例如 [Open Source Asset Pricing](https://www.openassetpricing.com/data/)，提供股票级预测特征、信号和组合收益。 +3. **商业因子模型**：Barra、Axioma 等提供证券载荷、协方差和特质风险，但模型、许可与数据格式由供应商定义。 +4. **完整定价与风险引擎**：例如 [Open Source Risk Engine](https://www.opensourcerisk.org/)，覆盖复杂产品定价、市场风险与 XVA，系统边界远大于本项目。 +5. **组合观测与解释**：消费用户已有仓位和因子模型，负责接入、时点选择、质量门槛、风险规则、证据和展示。 + +公开生态没有一个被广泛采用、同时覆盖“任意仓位导出 + 任意证券因子载荷 + 组合身份 + 时点语义 + 风险策略”的统一契约。v0.4 的开源价值不是发明新的因子，而是在第 5 层提供严格、可替换、适合自托管的桥接协议。 + +## 设计原则 + +1. **语义先于数值**：每个结果必须说明仓位基础、归一化方式、因子模型、模型版本和数据时点。 +2. **确定性内核**：计算、质量门槛和风险规则只使用 Decimal 与版本化输入，不调用 AI。 +3. **不把未知当作零**：缺失因子载荷、匹配失败和过期模型必须进入覆盖率或不可用状态。 +4. **不使用未来数据**：模型选择同时尊重模型 `as_of`、可获得时间和统一评估时点。 +5. **不静默重归一化**：缺失载荷时，已匹配仓位的贡献仍使用原分母；不把残余仓位重新放大到 100%。 +6. **风险策略绑定口径**：阈值必须绑定模型身份、模型版本和归一化方式。 +7. **输入原子化**：因子模型是一个整体；任何结构错误都拒绝整次导入，不生成残缺快照。 +8. **本地优先**：核心流程不需要行情服务、券商凭据或云 API；因子文件不会自动发送给 AI。 +9. **运营健康与风险健康分离**：策略是否正常运行和组合是否触碰风险阈值是两个独立状态，不合并成一个模糊灯号。 + +## 范围 + +### v0.4.0 包含 + +- 版本化 Factor

sensitivity" + }, + { + "factor_id": "value", + "display_name": "Value", + "unit": "z_score" + } + ] +} +``` + +约束如下： + +- `model_id` 和 `model_version` 使用稳定 ASCII 标识，最大 128 字符。 +- `as_of` 与 `available_at` 必须是 UTC 时间，且 `available_at >= as_of`。 +- `available_at` 表示上游数据在经济意义上可获得的最早时间，不是本地导入时间。 +- `factor_id` 在模型内唯一，使用小写 ASCII、数字、下划线和连字符，最大 64 字符。 +- 因子最多 128 个；manifest 最大 1 MiB。 +- `unit` 只描述上游载荷语义，不改变计算公式。`beta`、`z_score`、`score` 和 `custom` 都是普通线性载荷。 +- 模型方法变化必须提升 `model_version`；同一方法的每日数据只更新 `as_of`。 + +### 载荷文件 + +CSV 使用固定身份列与 `factor.` 前缀： + +```csv +instrument_id_type,instrument_id,venue,factor.market_beta,factor.value +ticker,AAPL,XNAS,1.12,-0.31 +ticker,MSFT,XNAS,0.94,0.18 +``` + +JSON 和 JSONL 记录使用： + +```json +{ + "instrument_id_type": "ticker", + "instrument_id": "AAPL", + "venue": "XNAS", + "factors": { + "market_beta": "1.12", + "value": "-0.31" + } +} +``` + +数值必须是有限定点 Decimal；CSV 空单元格和缺失 JSON key 表示 unknown，不表示 `0`。显式字符串 `"0"` 才是零载荷。数据文件限制为 100 MiB、100,000 个证券和每条 1 MiB。 + +同一模型快照内，证券身份必须唯一；重复身份、未知因子列、重复 CSV 表头、非法数值、超限资源或 manifest 不一致会拒绝整份导入。因子缺失本身允许存在，但会降低对应因子的覆盖率。 + +## 因子模型持久化 + +DuckDB 增加三个逻辑实体： + +```text +factor_model_snapshots + snapshot_id, model_id, model_version, as_of, available_at, + recorded_at, source, manifest_hash, content_hash, source_file, + revision, is_current + +factor_definitions + snapshot_id, factor_id, display_name, unit, description + +factor_loadings + snapshot_id, instrument_id_type, instrument_id, venue, + factor_id, loading +``` + +自然键是 `(model_id, model_version, as_of)`。相同自然键与相同内容是重复；内容变化且 `recorded_at` 更晚是修订；更早的记录是 stale。导入使用单一事务，任何写入失败都不得留下部分 snapshot。 + +`content_hash` 覆盖规范化 manifest、证券身份、因子 ID、显式零和缺失结构。API 和报告引用 `factor-model:`、`manifest:sha256:` 和 `content:sha256:`。 + +## 时点选择 + +给定组合仓位快照时间 `snapshot_time` 和服务评估时点 `evaluated_at`，候选模型必须同时满足： + +```text +model_id / model_version 与策略一致 +as_of <= snapshot_time +available_at <= snapshot_time +recorded_at <= evaluated_at +``` + +在满足条件的 current 修订中选择最大的 `as_of`；相同 `as_of` 只允许一个 current 修订。 + +这套规则同时支持两种场景： + +- 当前监控：仓位快照只能使用在该仓位时点已经经济可得的最近模型。 +- 历史回放：把 `evaluated_at` 注入历史时点，当时尚未发布或尚未记录的模型不能被选择。 + +如果没有候选模型，结果为 `unavailable`，原因区分 `model_not_found`、`model_not_yet_available` 和 `no_model_before_snapshot`。 + +## 证券身份匹配 + +匹配只使用规范证券身份，不查看名称相似度： + +1. 优先精确匹配 `(instrument_id_type, instrument_id, venue)`。 +2. 若模型记录的 venue 为空，只在组合内相同 `(instrument_id_type, instrument_id)` 唯一时允许匹配。 +3. 同时存在 venue 精确记录和 venue 为空记录时，精确记录优先。 +4. 同一无 venue 记录可能对应组合内多个 venue 时，状态为 `ambiguous_identity`，不选择其中任何一个。 +5. 大小写、前后缀、连续合约、期权代码和证券别名不自动转换；这些转换必须发生在显式上游映射中。 + +输出同时提供匹配、未匹配和歧义数量。API 最多返回前 100 个问题身份，完整数量和稳定摘要始终保留，避免超大响应。 + +## 仓位系数与暴露公式 + +只考虑至少一个仓位度量非零的有效仓位。因子分析的基础优先级与通用集中度分析不同： + +```text +weight → exposure_value_base → market_value_base +``` + +原因是显式权重最接近用户定义的组合计算系数；若没有完整权重，风险敞口值通常比会计市值更适合衍生品和多空仓位。 + +### `provided_weight` + +当全部有效仓位都具有 `weight` 时： + +```text +coefficient_i = weight_i +``` + +系统不假设这些权重一定以 NAV、capital 或 gross 为分母，因此结果名称仍是 `factor_exposure`。上游若把某个因子定义为 beta，界面可展示该单位，但 QuantCockpit 不替上游证明该语义。 + +### `gross_exposure_value` + +当没有完整 weight，但全部有效仓位具有 `exposure_value_base` 时： + +```text +gross = Σ|exposure_value_base_i| +coefficient_i = exposure_value_base_i / gross +``` + +### `gross_market_value` + +当前两种基础不完整，但全部有效仓位具有 `market_value_base` 时： + +```text +gross = Σ|market_value_base_i| +coefficient_i = market_value_base_i / gross +``` + +后两者在 `gross = 0` 时不可计算。只有 quantity 或所有可用基础都不完整时返回 `unavailable`，不得跨基础为不同仓位填洞。 + +对每个因子 `f`： + +```text +contribution_i,f = coefficient_i × loading_i,f +factor_exposure_f = Σ contribution_i,f +``` + +多头和空头方向已经包含在有符号仓位基础中。分析使用 Decimal、38 位局部精度和 ROUND_HALF_EVEN；对外比例与暴露最多保留 18 位小数。 + +缺失载荷时不重新归一化已匹配仓位。Top-N 贡献证券按 `abs(contribution)` 降序、证券身份稳定排序；API 默认返回前 5 个。 + +## 覆盖率与新鲜度 + +每个因子分别计算： + +```text +count_coverage_f = 具有该因子载荷的有效仓位数 / 有效仓位数 +economic_coverage_f = Σ|已覆盖仓位的原始基础值| / Σ|全部仓位的原始基础值| +``` + +`provided_weight` 的原始基础值是 weight；另两种模式使用归一化前的 base value。风险判定只使用 economic coverage，count coverage 用于诊断。 + +模型年龄为： + +```text +model_age_seconds = max(snapshot_time - as_of, 0) +``` + +覆盖率不足仍可展示部分因子暴露和贡献，但不得通过风险策略产生 `healthy`。界面必须同时显示覆盖率、缺失绝对基础值和问题身份。 + +## Portfolio Factor Policy 1.0 + +策略示例： + +```json +{ +

-q` + +Expected: FAIL because factor fixture import and benchmark script are absent。 + +- [ ] **Step 4: 添加两组合成仓位、两期模型与两份策略** + +演示数字固定为可手算值：AAPL weight `0.6`、MSFT weight `-0.4`；market_beta 分别 `1.0`、`0.8`，组合暴露 `0.28`。第二组合设置 market_beta `0.41` 触发 critical；另一个证券故意缺少 value 载荷，使 value economic coverage 低于 `0.95` 并展示 unavailable 质量门槛。所有 identity 使用 `paper` 和 `synthetic-demo`。 + +- [ ] **Step 5: 扩展 import_demo 且保持失败可见** + +```python +for manifest_path in sorted(factors_dir.glob("*-model.json")): + manifest = FactorModelManifest.model_validate_json(manifest_path.read_text(encoding="utf-8")) +

status={result.status}") +``` + +为脚本增加 `--factors-dir` 和 `--factor-policies-dir`；任何因子或策略导入失败都保持非零退出，不吞异常。 + +- [ ] **Step 6: 实现可重复 benchmark** + +`benchmark_factors.py` 使用固定 seed 生成临时 CSV、manifest、仓位事件和策略，只打印一行排序 JSON。计时使用 `time.perf_counter()`；数据库大小在关闭 store 后读取。默认参数正好是 `100000/20/10000`，测试显式传缩小参数。 + +- [ ] **Step 7: 跑缩小基准与完整 100k/20 基线** + +Run: `uv run pytest

`0.4.0`。README 的最短路径必须包含： + +```bash +uv sync +uv run quantcockpit factors preview ./loadings.csv --manifest ./factor-model.json +uv run quantcockpit factors import ./loadings.csv --manifest

的差异，并写明结果不是交易建议或自动生成的 beta 证明。 + +- [ ] **Step 2: 写完整因子接入与贡献文档** + +`docs/factors.md` 必须给出 manifest、CSV、JSONL、policy 的完整有效示例；解释 UTC 三时点、缺失非零、venue 匹配、覆盖率、阈值闭区间、原子失败和错误码。CONTRIBUTING 增加合成 fixture、手算预期和禁止提交商业模型数据的要求。 + +- [ ] **Step 3: 同步架构、安全与变更日志** + +在 `docs/architecture.md` 增加 factor model/policy store、纯函数分析器、服务解析顺序和独立风险健康。SECURITY 明确因子文件可能是机构专有数据、不会发送给 AI。CHANGELOG 列出 v0.4.0 功能、限制和不包含的协方差/VaR/收益回归。 + +- [ ] **Step 4: 扩展 Makefile 的显式基准入口** + +```make +.PHONY: factor-benchmark + +factor-benchmark: + uv run scripts/benchmark_factors.py --instruments 100000 --factors 20 --positions 10000 --database /tmp/quantcockpit-factor-benchmark.duckdb +``` + +不要把 100k benchmark 放入默认 `make verify`；默认验证只运行缩小 smoke test，避免 CI 时间不稳定。 + +- [ ] **Step 5: 跑完整后端、前端、无 AI extra 与构建验证** +

Task 1–4 建立可独立使用的因子模型输入与版本存储；此时尚不对外声称具备风险分析。 +2. Task 5–7 建立纯函数计算与风险规则；必须先用手算测试锁定语义，再接数据库。 +3. Task 8 是最高风险集成点；模型/策略歧义、时点和证据链需单独审查通过。 +4. Task 9–11 只暴露服务层结果，不得复制计算公式。 +5. Task 12–13 用合成演示、规模数据和完整验证证明发布边界。 + +每个任务只在对应测试先失败、最小实现通过、相关回归通过后提交。若实现中发现设计语义需要变化，先更新 `docs/superpowers/specs/2026-07-20-v0-4-factor-exposure-monitoring-design.md` 并记录原因，再继续代码。 diff --git
