+# Issue #32 文档来源测试报告
+
+状态：Draft，完成来源和证据工具层验证，尚未完成 LLM / Electron UI 验收。
+
+## 环境
+
+- Windows NT 10.0.26200.0
+- Bun 1.4.2 (744846f84)
+- 基线 main commit: `6a9a288eb354c01ae39a0339c902dd38e94ee89c`
+
+## 实际执行结果
+
+```text
+bun test packages/shared/src/research-documents
+30 pass / 0 fail / 62 assertions
+
+bun test packages/core packages/shared --isolate
+899 pass / 1 fail / 3410 assertions
+
+bun run typecheck
+core / i18n / shared / ui / electron: all exit 0
+
+git diff --check
+exit 0
+
+bun scripts/research-documents-live.ts
+PASS: production registry -> generated tools -> real SEC / Apple documents -> evidence
+```
+
+Focused tests cover issuer validation, historical periods, amendments, partial failures,
+cancellation, evidence offsets and hashes, real tool wiring, research EvidenceRef propagation,
+redirect restrictions, request headers, access denial and response size limits.
+
+## 已知失败及基线对照
+
+`PiRuntimeAdapter > removes the session conversation file on disposeSession` fails at
+`packages/shared/src/agent/pi-runtime-agent-backend.test.ts:621`: the Windows sandbox
+denies creating `/tmp/pi` (resolved to `C:\tmp\pi`).
+
+Running `bun test packages/shared/src/agent/pi-runtime-agent-backend.test.ts` in a clean
+worktree at the base commit produces the same failure: 16 pass / 1 fail / 31 assertions.
+The failing test and implementation are unchanged by this PR. This comparison is against
+the recorded base commit, not a claim that the latest upstream main has been tested.
+
+## 真实来源验证
+
+Run at 2026-09-11T12:50:18Z with SEC contact information supplied through an environment
+variable (not committed). No fixtures replace the provider responses.
+
+- SEC: Apple 10-K, filed 2025-10-31, reporting period 2025-09-27,
+  accession `0000320193-25-000079`; extracts `Net sales` evidence from the actual HTML.
+- Apple: current official Newsroom feed and a linked official announcement; reporting
+  period remains absent when not provided by the publisher.
+- Both use the same issuer identity and return source types, document IDs, bounded
+  evidence spans, SHA-256 content hashes and text-fragment source links.
+
+The script prints a Markdown source report and is reproducible with the command above.
+Feed contents and normalized offsets may change. This is provider/tool integration,
+not an LLM-generated final investment answer or an Electron UI E2E result.
+
+## 待完成验收
+
+- Run an actual Agent research conversation and inspect final citations.
+- Verify visible research output in Electron and attach screenshots before review.
+  The local Electron executable is unavailable; no UI pass is claimed.
+- Current IR connector covers Apple Newsroom only; PDF extraction and paid research
+  connectors are outside this draft's implemented scope.
+
+The full Issue #32 is not claimed complete by this draft.

+# 金融研究文档来源（Issue #32）
+
+`research.documents` / `search_research_documents` 和
+`research.documentEvidence` / `get_document_evidence` 在 production full registry 注册，
+因此 Electron main 和 Pi 生成的工具使用同一套 manifest。默认和 comprehensive 深度研究计划接入文档检索。
+
+## 来源与覆盖范围
+
+- SEC EDGAR：Submissions API 的 recent 列表；指定报告期或发布日期时，读取匹配的历史文件。
+  单次最多 20 个历史文件，超出时返回明确错误，要求缩小日期范围，不静默截断历史。
+  内置 AAPL/NVDA/TSLA/MSFT CIK；其他美国上市公司可提供 CIK，API 返回的 ticker 必须与 symbol 一致。
+- Apple 官方 Newsroom Atom：首版 IR/公司公告连接器，仅覆盖当前 RSS 窗口。
+  不把缺少报告期的公告冒充为指定财政年度的财报。每次返回覆盖范围和各来源状态。
+- 第三方研报：独立 `ResearchReportAdapter` 契约明确 source type 和许可范围；未接入付费服务，
+  不抓取付费全文，也不把研报观点提升为监管披露。
+
+SEC 要求设置 `FINAGENT_SEC_USER_AGENT`（访问者名称和联系邮箱），仅传给 SEC 官方主机。
+不要提交真实值。参见 [SEC API 文档](https://www.sec.gov/search-filings/edgar-application-programming-interfaces)
+和 [SEC 访问要求](https://www.sec.gov/about/developer-resources)。未配置会报告具体错误，不生成假财报。
+
+## 查询与证据
+
+参数支持 symbol、CIK、subtype、periodEnd、publishedFrom、publishedTo、authority、limit。
+subtype 为 `10-K` 时包括 `10-K/A`；精确查询 `10-K/A` 只返回修订。
+周期报告按 issuer + base form + period 建立 version family，仅存在唯一原始报告时填入 amendment 关系。
+8-K 不因同一天发布而武断地归为同一个文件。
+
+可传 `evidenceQuery` 从至多两个来源各抽取一份 HTML 文档的证据，也可以直接调用 evidence 工具。
+结果包含 document ID、SHA-256、规范化文本偏移、至多五段有界引用和 `#:~:text=` 跳转。
+偏移不是 HTML 字节位置，不编造页码或 section。PDF 暂不支持；未命中不代表事实不存在。
+现有 `EvidenceRef` 向后兼容地增加 document ID、source type、canonical URL、document evidence。
+来源文本只是非可信证据，不能覆盖 Agent 指令。
+
+HTTP 只允许 SEC 和 Apple 固定官方主机，每次重定向重新校验；限制超时、15 MB 响应大小、
+SEC 请求速率。不会读取任意用户 URL 或绕过访问拒绝。服务不保存全文或主动写 telemetry；
+调用方应遵守 licensing 中的 `telemetryAllowed: false`，不要导出引用正文到追踪平台。
+
+## 可复现验证
+
+```sh
+bun test packages/shared/src/research-documents
+bun test packages/shared/src/capabilities packages/shared/src/research packages/shared/src/strategies
+bun run typecheck
+# 在本地环境配置 SEC 联系信息后：
+bun scripts/research-documents-live.ts
+```
+
+Live 脚本不使用 fixtures，经 production registry 和生成的 Agent 工具检索 Apple 真实 10-K 和官方公告，
+定位财报内 `Net sales`，输出带来源类型与证据跳转的 Markdown 来源研究报告。
+它不等同于 LLM 决策或 Electron UI E2E；这两个层面的测试应单独报告，不能以脚本成功替代。
