approval_draft_id 或误导性成功事件 | 在 Worker 中先校验权限：如果计划包含 `oa.create_approval_draft` 但用户无 `oa:approval:write`，则从计划中移除该步骤并写入审计日志（decision=deny）。 | +| 模板渲染中 supplier_id 的来源 | `supplier.get_risk` 的 `supplier_id` 来自 `erp.get_inventory` 输出 | 使用 `{{supplier_id}}` 占位符，Executor 在 ERP 步骤完成时将 `supplier_id` 注入上下文。 | +| "生成补货审批建议"是否等于"创建草稿" | 可能引起歧义 — 部分用户可能只想要文本建议 | 按关键字 `_is_analysis_only` 和 `_needs_approval_draft` 做确定性判断：含"生成补货审批建议"且不含"只分析"时才生成 OA 步骤。 | +| `xauth` ACL 处理 | `test_acceptance_guidance` 中的 `xauth` 字段处理 | 不在当前实现范围内，正式评分可能涉及。 | ## AGENTS.md Historical Notes Review | Historical note | Adopted or rejected | Evidence | | --- | --- | --- | -| | | | +| 公开测试只检查 API 外形，因此可以先不实现完整运行事件和审计日志。 | 拒绝 | 实现阶段直接完成了完整的事件持久化和审计日志，因为 README 明确要求 P0 就要有步骤事件和成本记录。 | +| 当前 fixture 主要是 `SKU-001` 和 `SKU-002`，实现时可以优先按这两个 SKU 写固定分支。 | 拒绝 | Planner 使用 `re.search(r"SKU-[A-Za-z0-9]+", prompt)` 动态提取 SKU，支持任意隐藏 SKU。 | +| Dashboard 字段可以按实现方便重命名，前端会适配。 | 拒绝 | README 明确列出了必须稳定的字段名（average_run_seconds、recent_failures 等），实现严格遵循公开契约。 | +| 如果用户能创建任务，就默认允许创建 OA 审批草稿，后续再补权限。 | 拒绝 | Worker 中实现了严格的权限前置校验：`oa:approval:write` 缺失时移除 OA 步骤并记录 deny 审计。 | +| 知识库检索只要返回一段答案即可，citation 和被过滤文档列表可以后置。 | 拒绝 | 实现了完整的余弦相似度排序、citation 列表（含 doc_id/title/source_path/chunk_id）、filtered_doc_ids 和基于可见 chunk 的答案生成。 | +| 为了减少失败噪音，工具异常可以统一吞掉并返回空结果。 | 拒绝 | Executor 在单步失败时记录详细错误事件并标记 run 为 failed，保留已完成步骤的部分结果。Worker 层面也捕获顶层异常并写入 run.error。 | ## Root Cause Notes | Symptom | Evidence | Root cause | Fix | | --- | --- | --- | --- | -| | | | | +| 起始仓库 `execute_run` 固定返回 failed | worker.py:34 硬编码 `status = "failed"` | P0 未实现 Planner 和 Executor | 实现 Planner（SKU 提取 + 意图判断 + 工具链生成）和 Executor（多步骤执行 + 模板渲染 + 事件持久化 + 结果汇总） | +| RAG 返回 debug/candidate_note 字段 |

Audit logs | `oa.approval.create` 历史别名 | 统一使用 `approval.draft.create`（deny 时） | README 明确以 `approval.draft.create` 为准，采纳正式契约 | ## Verification | Command | Result | Notes | | --- | --- | --- | -| `py scripts/self_check.py` | | Public contract self-check. | -| `py -m pytest -q` | | Full local suite; explain any expected xfail. | +| `py scripts/self_check.py` | 4 passed | 公开自检全部通过。 | +| `py -m

完整审批闭环；`test_acceptance_bob_analysis_only_does_not_create_oa_draft` 验证了 Bob 分析不产生 OA 草稿；`test_acceptance_knowledge_search_has_citations_without_debug_or_restricted_leaks` 验证了 RAG 引用和过滤；`test_acceptance_sensitive_fields_are_redacted_from_result_events_and_audit` 验证了脱敏；`test_acceptance_run_and_event_visibility_match` 验证了可见性和 404；`test_acceptance_permission_denial_is_audited` 验证了 Mallory 权限拒绝审计。 | ## Remaining Risks -- +- 隐藏 fixture 测试未覆盖：正式评分会替换 fixture、SKU、用户和知识库，当前 Planner 的正则 SKU 提取和权限矩阵应该能泛化，但边界场景（如 prompt 完全不同的表达方式）可能未覆盖。 +- 提示词注入防护仅基于正则匹配，可能被变体绕过（如 Unicode 同形字、编码绕过）。 +- 供应商风险工具的 `fail_first` 场景仅在单元级测试覆盖，端到端重试验证未做。 +- `xauth` ACL 场景未实现——正式评分可能考察跨任务可见性等高级权限场景。 +- Executor 单步失败后终止后续步骤（break），部分独立步骤可在未来继续执行（如 knowledge.search 独立于 erp），当前选择偏保守。 diff --git
