+# Phase 13 Legal Knowledge And Template Library
+
+This package is the production pilot data foundation for the AI Contract Platform legal knowledge base and contract template library.
+
+Current scope:
+
+1. Mainland China enterprise civil and commercial contract scenarios.
+2. Official legal source inventory.
+3. Legal knowledge card schema.
+4. Contract review risk rule schema.
+5. Standard clause library schema.
+6. Contract template schema.
+7. Golden sample schema for review, generation, and KB Q&A.
+8. Expert review register schema.
+
+Important rules:
+
+1. Do not store real customer contracts, personal information, secrets, Webhook URLs, or administrator passwords in this package.
+2. Third-party articles may only be clues. They cannot be final legal authority.
+3. A source can become production-ready only after official source detail, validity, and legal reviewer fields are completed.
+4. Generated contracts and review findings must cite source IDs instead of unsupported model memory.
+5. This package supports legal and business review. It does not replace advice from qualified legal professionals.
+
+Status:
+
+- Phase 13.0 schema baseline: in progress.
+- Phase 13.1 official source inventory: in progress.
+- Production publishing: blocked until legal/business review is complete.

+# AI合同平台 阶段 13 法律知识库与合同模板库建设闭环第一批执行记录（2026-05-01）
+
+## 一、阶段结论
+
+阶段 13 第一批已完成 `13.0 治理口径与资料 schema` 和 `13.1 法源资料采集` 的工程化底座，当前状态为 `PASS_WITH_LEGAL_REVIEW_REQUIRED`。
+
+本批次不是最终生产发布，而是把法律知识库与合同模板库从“想法”落成可校验的资料包结构、清单 schema、第一批官方法源采集任务和自动化门禁。所有法源均标记为 `LEGAL_REVIEW` 和 `VERIFY_REQUIRED`，在法务复核完成前不得作为生产确定性依据。
+
+## 二、本批次交付
+
+新增资料包：
+
+`project-docs/phase13-legal-knowledge-template-library/`
+
+关键交付物：
+
+1. `README.md`
+2. `governance-rules.md`
+3. `field-dictionary.md`
+4. `inventories/legal-source-inventory.csv`
+5. `inventories/legal-knowledge-card-inventory.csv`
+6. `inventories/review-risk-rule-inventory.csv`
+7. `inventories/clause-library-inventory.csv`
+8. `inventories/contract-template-inventory.csv`
+9. `inventories/review-golden-sample-inventory.csv`
+10. `inventories/generation-golden-sample-inventory.csv`
+11. `inventories/kb-qa-golden-sample-inventory.csv`
+12. `inventories/expert-review-register.csv`
+13. `legal-sources/*/README.md`
+14. `clause-library/*/README.md`
+15. `contract-templates/*/README.md`
+16. `qa-samples/*/README.md`
+17. `evidence/README.md`
+18. `scripts/run-legal-knowledge-library-gate.ps1`
+
+## 三、第一批法源范围
+
+第一批已建立 `20` 条官方法源采集任务，覆盖以下知识域：
+
+1. `civil-code`
+2. `judicial-interpretations`
+3. `company-commercial`
+4. `labor-employment`
+5. `procurement-tendering`
+6. `data-privacy`
+7. `intellectual-property`
+
+法源入口仅允许白名单官方域名，包括：
+
+1. `flk.npc.gov.cn`
+2. `www.npc.gov.cn`
+3. `www.court.gov.cn`
+4. `gongbao.court.gov.cn`
+5. `www.gov.cn`
+6. `www.moj.gov.cn`
+7. `www.samr.gov.cn`
+8. `www.cac.gov.cn`
+9. `www.mohrss.gov.cn`
+10. `www.cnipa.gov.cn`
+
+## 四、自动化门禁结果
+
+执行命令：
+
+```powershell
+powershell.exe -NoProfile -ExecutionPolicy Bypass -File scripts\run-legal-knowledge-library-gate.ps1
+```
+
+门禁输出：
+
+```text
+PHASE13_LEGAL_KNOWLEDGE_LIBRARY_GATE_PASS_WITH_LEGAL_REVIEW_REQUIRED D:\ai-contract-platform\project-docs\qa-artifacts\phase13-legal-knowledge-library-gate\2026-05-01T19-56-24-115
+```
+
+门禁证据：
+
+`project-docs/qa-artifacts/phase13-legal-knowledge-library-gate/2026-05-01T19-56-24-115/`
+
+门禁统计：
+
+| 指标 | 结果 |
+|---|---:|
+| 法源采集任务 | 20 |
+| 官方白名单域名 | 10 |
+| 知识域覆盖 | 7 |
+| Inventory 文件 | 9 |
+| 必需失败项 | 0 |
+| 法务复核待办 | 20 |
+
+说明：本批次在提交前运行，因此存在非阻塞工作区提示。提交后需再次运行同一门禁，确认工作区干净状态。
+
+## 五、当前保留项
+
+| 保留项 | 状态 | 说明 |
+|---|---|---|
+| 法源详情页确认 | LEGAL_REVIEW | 当前 `source_url` 记录官方入口，后续需补充或确认官方详情页 |
+| 生效日期与有效状态 | VERIFY_REQUIRED | 不在未复核状态下写死可能变化或可能误记的生效信息 |
+| 法律专家复核 | PENDING | `legal_reviewer` 当前为 `pending` |
+| 生产发布 | BLOCKED_BY_REVIEW | 复核完成前不得进入生产索引或作为确定性依据 |
+
+## 六、下一步
+
+下一批应进入 `13.2 法律知识卡建设` 和 `13.3 合同审核规则库`：
+
+1. 对 20 条法源逐条补充官方详情页、有效状态和法务复核记录。
+2. 从民法典合同编和合同编通则司法解释开始拆解法律知识卡。
+3. 先建立付款、违约、解除、争议解决、保密、知识产权、数据处理等高频审核规则。
+4. 将审核规则绑定法源 ID、严重等级、修改建议和黄金样本。
+
+阶段 13 第一批当前状态：`PASS_WITH_LEGAL_REVIEW_REQUIRED`。
