覆盖 AC-50/51/52(BR-48/49、E-28)。审计确认的 P1-3 缺口"历史提炼与卡片 不在实时 API 调用图上"由此关闭:提炼、候选治理、卡片进方案全部有真实调用方。 后端: - contracts:新增 E-28 EXTRACTION_UNAVAILABLE(运行级,不进 HTTP 信封)与 KnowledgeExtraction 记录类型。契约层强制"失败不得带候选", AC-50「模型不可用⇒不产生候选」是类型约束而不是文档约定。 - services/experience_extraction.py(新):真实提炼入口。模型不可用或调用失败 → 记 E-28 且 candidate_id 为空;不产半成品候选。传输纪律同 assistant_model (禁进程内代理、零重试),且 tools=[] 使"越权读材料"在结构上不可能。 自然语言修订同样必须真实调用模型,没有"把中文猜成条件"的回退路径。 - services/knowledge_cards.py:新增 current_draft/revise/list_cards 与 registry_conditions。修订只产草稿、保留 origin 与来源、升版本记 parent_version; test_cases 纳入可改字段——它是 component_evaluation 对自定义 Skill 的发布门禁, 不开放则提炼出的候选永远卡在评测门外。 - services/project_assistant.py:enqueue 改用 review_plan.assemble(), 让 T06-b 的依赖预检(E-19 可定位文案)与维度解析不再被绕过。 - api/prescreen.py:case-timeline、knowledge-extractions、knowledge-candidates (创建/修订/状态机)、review-plans(装配/状态机)。角色门禁与既有 /components 入口一致;id 与数据域由服务端生成;按 id 的路由一律在 run() 内 查归属,否则 KeyError 会变成 500 而不是 404。 - component_registry/review_plan:下沉 current_draft/version_key 与 list_plans。 前端: - 新增 /experience-center 独立入口(BR-50)与 ExperienceCenter 组件; AgentNav 增加「历史经验加工」。 - originBadge 此前零调用方、.origin-* 无任何 CSS——守卫只 grep 库文件字符串, 于是"测试通过但功能不存在"。本批补齐消费方与样式,并用左边框样式区分四种来源, 保证去色仍可区分(AC-42/BR-48)。 - 守卫语义按 AC-55 调整:由"禁止新建路由"改为"禁止重复页面" (面板不得搬到独立路由、已合并页必须保持重定向),并新增 experience-center-ui 守卫(已登记 verify.py,共 12 项检查)。 测试:新增 36 项(提炼 15 / 候选治理 15 / 卡片到运行 6),全量 unittest 无回归; 两次同项目运行对照证明卡片确实改变了核查结果,且 basis_ids 指向 卡片id@版本。 未闭合(记录在 17 的剩余缺口):真实模型提炼尚未实测(需端点); 界面未经浏览器点击验证;例外边界未进入可求值语言;规则类候选不在本批。 Co-Authored-By: Claude Code <noreply@anthropic.com>

"""纠偏第二批 · 历史经验真实提炼入口(BR-48 / AC-50 / E-28)。
|
||
|
||
依据:`docs/v2/16-delivery-corrections.md` §1(BR-48)、§2(E-28)、§3(AC-50);
|
||
`docs/v2/14-experience-loop.md` §4(加工步骤:恢复时间线 → 聚合证据 → 生成候选 → 专家修改)。
|
||
|
||
审计(`test-evidence/20260930-v2-audit/audit.json` P1-3)确认:历史提炼此前**没有任何
|
||
调用方**,"大模型提炼"只有"带 feedback_id 的预审运行"这一条路径。本模块补的就是这条入口。
|
||
|
||
三条硬规则,每条都有对应测试,不靠文档约定:
|
||
|
||
1. **真的调用模型**。展示"大模型提炼"就必须实际发起调用,没有确定性回退路径假装成功。
|
||
2. **不可用即未完成**。未配置模型或调用失败 → 记 E-28,且 **candidate_id 保持为空**。
|
||
`KnowledgeExtraction` 契约在类型层拒绝"失败却带候选"这种写法。
|
||
3. **来源不可洗**。产出的候选一律 `origin=history_derived` 且携带来源事件 id;
|
||
无来源的历史卡片会被 `knowledge_cards.propose()` 直接拒绝。
|
||
|
||
**本切片只产出 Skill 类候选**(可验证的缺件核查动作),理由不是省事:
|
||
|
||
- Rule 类候选需要数值阈值(`component_registry.validate()` 要求 threshold 可解析为数值)
|
||
与正式依据门禁(`_check_hard_basis()`),历史提炼只能给出"建议",其设计与验收须单独定案;
|
||
- 例外边界("已有到账凭证则不触发")在注册表条件语言里没有对应算子——
|
||
`knowledge_cards._translate_conditions()` 只映射数值阈值算子,且 `present` 被既有测试
|
||
`test_conditions_are_validated` 锁定拒绝。因此本切片把例外保存为**说明文本**
|
||
(`exception_note`)供专家修订,**不冒充成可执行条件**。
|
||
|
||
这两条是如实记录的缺口,不是已完成项。
