-- **计划(原 M1)**:来源 A 从票圈样本帖挖"具体的点",**限每需求 5 篇代表帖**;灵感点直收 / 目的点清洗动作词 / 关键点弃。证据:§6 M1(来源 A 段落)。
-- **现状**:代码 `search_intent._v4_piaoquan_point_candidates` 实际**只吃 evidence_pack 内联的 `sample_elements`**(demand 33 仅 2 个),而 PG 里该需求有 **369 个点(用了 0.5%)**;无覆盖度排序、无 top-K、无类型配额。
-- **差距**:真去 PG 反查——`pattern_itemset_post`→支撑帖(过滤 `platform=票圈`)→`post_decode_topic_point` 取全部点位 → 类型过滤(灵感>目的(清洗)>>关键点弃)→ 质量过滤(2–10 字、去"式/感/构图/字幕/剪辑/旁白"手法词)→ 按**覆盖度(出现帖数)排序** → **自适应 top-K**(K≈18,灵感60%+目的40%,永远带 seed_terms,小需求兜底)。归一**简单版(topic_point_result 覆盖度排序)起步**,语义聚类(`global_element_semantic_cluster` 5585 行)列 v2。**待拍**:架构(上游 DemandAgent 预筛进 evidence_pack vs 运行时连 PG)、K 上限。规模差 50×(23~1161 帖)需自适应。
+### M12 取词演进:用上游 `query_seed_points` 当首轮搜索词池(M1 增强)
+
+> 依据:上游 `DemandAgentNew/analysis/cfa_demand_content_v2_contract.md`(代码 `86ec3c6`)。
+
+- **一句话**:以前 CFA 自己从需求里夹带的一两个"样本点"抠搜索词,覆盖率极低;现在上游 DemandAgent V2 已经帮我们把搜索点位算好了(`query_seed_points`),CFA 直接拿来用,不用自己连 PG。
+
+- **上游现在怎么给的(V2 契约)**:
+  - 需求不再只靠"频繁项集(itemset)"。现在有 **5 类证据来源**(高权重元素 / 高权重分类 / 元素共现 / 分类共现 / itemset),**很多需求根本没有 itemset**。
+  - `query_seed_points`:从这条需求**所有真实支撑帖**里,挑出 **灵感点/目的点**(丢关键点,关键点多是制作手法),按 `point_text+point_type` 去重,按**覆盖度**(`coverage_post_count`,这个点出现在多少篇帖里)从高到低排,默认 **Top 30**,带 `rank`(1..30)。这就是给 CFA 的**首轮搜索池**。
+  - `seed_terms`:需求的短词骨架(如"励志情感歌曲""歌词唱词"),上游定位为**轻量召回 / 兜底词**,不是主搜索池。
+  - `element_bindings`:上游契约**明确写了它不是搜索池**,只是"这条需求为什么真实"的证据样本,供**展示/溯源**用。
+
+- **CFA 落地状态(已完成)**:`query_seed_points` 已透传进 `pattern_seed_pack`,并成为 V4 首轮搜索池主路;`element_bindings` 的 `point_text` / `name` 两条旧取词路已撤掉。旧需求或 `query_seed_points` 为空时,回退 `seed_terms`。
+
+- **CFA 要怎么改(本次定稿)**:
+  1. **首轮搜索池主用 `query_seed_points`**,按 `rank` 从高到低用;目的点仍套现有前缀剥离(`_cleanup_purpose_point`)+ 通用词过滤,但**不覆盖原始 `point_text`**(契约要求另存 cleaned query)。
+  2. **`seed_terms` 当兜底**:`query_seed_points` 为空时(或旧 demand)回退用 `seed_terms`,保证永远有词可搜、不空跑。
+  3. **`element_bindings` 退出取词**:现在跟上游口径对齐——`point_text` 路和 `name` 路都不再从它取词(`name` 路本来还会把关键点漏进搜索词)。它在 CFA 只保留**展示/溯源**用途(flow_ledger 需求卡片、query 来源回溯),上游仍会发,**不要求停传**。
+
+- **接之前必须先改的前置:入口校验对齐"多来源"契约(全渠道生效,优先级高于取词)**
+  - V2 现在的证据来源有 **5 类 + multi_source**:`high_weight_element`(高权重元素)/ `high_weight_category`(高权重分类)/ `element_co_occurrence`(元素共现)/ `category_co_occurrence`(分类共现)/ `pattern_itemset`(频繁项集);一条需求被多类撑着时 `source_kind=multi_source`。**只有 `pattern_itemset` 才有 itemset(项集 ID/明细/mining_config),前四类没有 itemset。**
+  - CFA 入口 `source_context._validate_pg_evidence_pack` 是**按"每条需求都是 itemset"写死的**,会拦死非 itemset 需求,两处根因:
+    - 固定值 `source_kind == "pattern_itemset"`([source_context.py:158](../../content_agent/business_modules/source_seed/source_context.py))→ 高权重/共现/multi_source **全被拒**(最严重)。
+    - 必填非空里有 `itemset_ids` / `itemset_items` / `mining_config_id`([:171](../../content_agent/business_modules/source_seed/source_context.py))→ 非 itemset 来源这几个为空,又被拒。
+  - **改法(已完成)**:① `source_kind` 改白名单(收 6 种合法值),不再写死 `pattern_itemset`;② itemset 三件套改"有条件必填"——仅当来源含 `pattern_itemset` 时才要非空;③ 必填项换成真实 142 条样本稳定非空的**地基字段**(`category_bindings`/`element_bindings`/`seed_terms`/`matched_post_ids`/`video_ids`/`case_ids`/`source_post_id`/`pattern_execution_id` + 固定值 + `source_post_id∈matched_post_ids`),`evidence_sources` 仅最新批次有(12/142),不列无条件必填;④ `query_seed_points` 只验"是数组",可空(空了走 seed_terms 兜底)。
+  - **客观取舍**:这道校验是 CFA 二道防线,上游写库前已 DB 强校验,CFA 这层主要防"手塞脏 demand";可只保地基字段非空(中间档),不必跟上游一样严。**不改 = 抖音/快手/视频号都只能收纯 itemset 需求(很可能是少数)。**
+
+- **改动面(落到具体函数)**:
+  1. `source_context._validate_pg_evidence_pack`:按上面"前置"放宽(白名单 source_kind + itemset 有条件必填)。
+  2. `source_context.build_pattern_seed_pack`([source_context.py:78](../../content_agent/business_modules/source_seed/source_context.py)):白名单里**新增透传 `query_seed_points`**(目前显式白名单不带它,字段会丢)。
+  3. `search_intent._run_v4`([search_intent.py:159](../../content_agent/business_modules/search_intent.py)):取词候选改为「**主 `query_seed_points`(新增一条候选构造,按 `rank` 升序)+ 兜底 `seed_terms`(`_v4_seed_candidates` 保留)**」;**删掉吊在 element_bindings 上的两条词路**——`_v4_piaoquan_point_candidates`(point_text 路,[:227](../../content_agent/business_modules/search_intent.py))和 `_v4_category_element_candidates`(name 路,[:266](../../content_agent/business_modules/search_intent.py));`query_seed_points` 为空时才走 `seed_terms`。
+  4. 溯源:新增 `query_seed_point` 来源类型(`query_source_type` / `generation_method`),带 `rank`/`coverage_post_count`/`point_type` 可复盘字段,替代旧 `piaoquan_topic_point`/`category_leaf_element`。
+  - **不连 PG、不改 DB runtime schema;`element_bindings` 仅退出取词,展示/溯源(flow_ledger)不动。**
+
+- **暂不做(列 v2)**:语义聚类归一;CFA 侧再设 K 上限 / 灵感目的配额(上游已 Top30 按覆盖度混排,CFA 先全用)。
 
 ### M13 Gate2 兜底:非抖音候选清空回退(M9D 增强)
 - **计划**:原 M9D 只规划 Gate2 yes/no 判定(拿不准从宽放过),**未规划"候选被全过滤后"的兜底**。
-- **现状**:`search_intent.py:175` 逐条过 Gate2,`:195` 候选全空即 `raise QUERY_GENERATION_FAILED` → **整条 run 失败**。抽象需求(根本观念/人物特征/叙事组织)在快手/视频号**必失败**(demand 9 / 87 本 session 复现两次)。
-- **差距**:候选被 Gate2 清空时**回退至少搜 `seed_terms`**(顶层 pattern 词,最稳),或对该需求放宽 Gate2,而不是整条 run 报错。目标:非抖音抽象需求至少有产出、不空跑失败。
-- 总验收报告 `status=pass`;三平台均真实生成 `search_queries/discovered_content_items/content_media_records/pattern_recall_evidence/rule_decisions/walk_actions/final_output/strategy_review`,并通过 DB runtime 回读、dashboard summary、timeline、final_output、strategy_review 与 `validate_run()`。
+- **现状**:`search_intent._run_v4` 里 `apply_gate2 = platform and platform != "douyin"`([search_intent.py:168](../../content_agent/business_modules/search_intent.py)),逐条过 Gate2([:178](../../content_agent/business_modules/search_intent.py));过滤后候选全空即 `raise _query_generation_error("v4_search_queries_empty")`([:198](../../content_agent/business_modules/search_intent.py))→ **整条 run 失败**。**仅快手/视频号触发,抖音豁免。** 抽象需求(根本观念/人物特征/叙事组织)在快手/视频号易复现(demand 9 / 87 本 session 两次)。
+- **与 M12 的关系**:M12 接 `query_seed_points` 后,Gate2 的输入词从"element_bindings 样本"换成"Top30 真实点位",**词更多、过 Gate2 概率更高,空失败风险整体下降**;但极端抽象需求仍可能被 Gate2 清空,M13 兜底**不可省**。
+- **差距(兜底逻辑)**:候选被 Gate2 清空时,按优先级回退,而不是 `raise`:
+  1. 已定为**单一 `seed_terms` 兜底**:Gate2 把 `query_seed_points` 全否时,直接用顶层 pattern 词 `seed_terms` 绕过 Gate2 产出,并标 `gate2_fallback=true`。
+  2. 不再放行被 Gate2 否掉的高 rank 窄词,也不在 `search_intent.run` 写 `query_failures`;`query_failures` 仍归平台搜索/渐进调度等下游环节负责。
+- **目标**:快手/视频号的抽象需求至少有产出、不再空跑失败;Gate2 仍对正常词生效(不是整体关掉)。
+- **验收**:三平台真实生成 `search_queries/discovered_content_items/content_media_records/pattern_recall_evidence/rule_decisions/walk_actions/final_output/strategy_review`,通过 DB runtime 回读、dashboard summary、timeline、final_output、strategy_review 与 `validate_run()`;总验收报告 `status=pass`。

+
+## 背景:三层风险(四个只读审计 subagent 交叉确认)
+1. **进程挂掉 / 成功率暴跌(全渠道)**:入口校验 `_validate_pg_evidence_pack` 写死 `source_kind=="pattern_itemset"` + itemset 三件套(`itemset_ids`/`itemset_items`/`mining_config_id`)必填。V2 的 6 种 source_kind 里 5 种(高权重元素/分类、元素/分类共现、multi_source)在第一步 `load_source` 就 `raise ValueError` → run 不产任何产物。**→ M12A 解决。**
+2. **筛选门槛被动抬高(隐蔽,不报错)**:`query_seed_points` 全仓零引用,取词仍吊在被上游降级的 `element_bindings` 两条词路上,首轮词池悄悄缩回到近乎只剩 `seed_terms`。**→ M12B 解决。**
+3. **Gate2 把 run 筛空(仅快手/视频号)**:词池缩水后 Gate2 易清空候选 → `v4_search_queries_empty` 整 run 失败。**→ M13 解决。**

+# M12A 入口校验对齐多来源契约 Implementation Brief
+
+## 状态
+已完成。本 brief 记录 M12 的**前置**改造:把 CFA 入口校验 `_validate_pg_evidence_pack` 从"假设每条需求都是 pattern_itemset"改为"按证据来源分情况"。核心原则:**让上游 V2 的 6 种 source_kind 都能进、非 itemset 需求不被误拒;但脏 demand / 旧 MySQL 仍拒。** 全渠道生效(抖音/快手/视频号一视同仁)。M12A 不改取词、不改 Gate2、不连 PG、不改 DB schema。
+
+## 目标
+1. `source_kind` 由"写死等于 `pattern_itemset`"改为 **6 值白名单**:`high_weight_element` / `high_weight_category` / `element_co_occurrence` / `category_co_occurrence` / `pattern_itemset` / `multi_source`。
+2. itemset 三件套(`itemset_ids`/`itemset_items`/`mining_config_id`)从"无条件必填"改为**有条件必填**——仅当来源含 `pattern_itemset` 时才要非空。
+3. 必填项换成上游契约 §16 保证非空的**地基字段**,既不误拒合法多来源需求,又能拦脏 demand。
+4. 只动 `_validate_pg_evidence_pack` 一个函数,其余链路零改。
+
+## 现有证据
+- `content_agent/business_modules/source_seed/source_context.py:148-192` `_validate_pg_evidence_pack`:
+  - `:149-155` 固定值校验 `pattern_source_system=="pg_pattern_v2"` / `validation_status=="passed"`(契约保证,保留)。
+  - `:157-169` 别名校验,其中 `("source_kind","pattern_scope"): "pattern_itemset"` **写死要求 source_kind==pattern_itemset**(根因①)。
+  - `:171-188` `required_fields` 含 `itemset_ids`/`itemset_items`/`mining_config_id`,`value==[] / "" / None` 即 `raise`(根因②)。
+  - `:190-191` `source_post_id ∈ matched_post_ids`(保留)。
+- 调用链:`load_source_context`(`:15`)→ `normalize_evidence_pack`(`:48`,`:55` `normalized.update(incoming)` 已全量透传所有字段)→ `_validate_pg_evidence_pack`(`:74`)。`load_source` 是 graph 第一个节点(`content_agent/graph.py:79`),此处 `raise` 直接终止整条 run、不产任何产物。
+- 上游契约 §16「最小验收 SQL / JSON 规则」列过 `evidence_sources`,但真实库回看发现它仅最新批次有(12/142),不能作为 CFA 入口无条件必填;本层只把它用于"是否含 pattern_itemset"的条件检测。`query_seed_points is array`(可空);itemset 字段未列入"非空"。§5 说明 `mining_config_id` 非 itemset source 可为空。§6 列 5 类 source_kind + multi_source。
+
+## 修改范围(最小:仅一个函数)
+`content_agent/business_modules/source_seed/source_context.py` 的 `_validate_pg_evidence_pack`:
+- **改 source_kind 校验**:把 `("source_kind","pattern_scope"): "pattern_itemset"` 的"严格相等"改为"值 ∈ 6 元素白名单";`case_id_type==post_id` / `source_certainty==db_validated` 两条别名校验保持。
+- **itemset 三件套有条件必填**:`itemset_ids`/`itemset_items`/`mining_config_id` 从 `required_fields` 移出;仅当 `source_kind=="pattern_itemset"`,或来源含 itemset(`evidence_sources` 里存在 `source_kind=="pattern_itemset"` 的项)时,才校验它们非空。
+- **必填项换地基字段**:`required_fields` 改为 `source_post_id`、`pattern_execution_id`、`matched_post_ids`、`video_ids`、`case_ids`、`seed_terms`、`category_bindings`、`element_bindings`、`support`、`absolute_support`。`evidence_sources` 不列无条件必填,只在 itemset 条件检测里使用。
+- `source_post_id ∈ matched_post_ids` 保持。
+
+## 不修改范围(禁区)
+- 不改 `normalize_evidence_pack` 的透传逻辑(`:55` `update(incoming)` 已带入 `query_seed_points`/`demand_scope`/`evidence_sources`,不动)。
+- 不改 `build_pattern_seed_pack`;特别是 `:90` `evidence_pack["pattern_execution_id"]` **硬下标保留**(契约保证恒有值)——**放宽校验时务必让 `pattern_execution_id` 仍在 required_fields 里,别误删,否则这里变 KeyError**。
+- 不动固定值校验(pattern_source_system/validation_status/case_id_type/source_certainty)——旧 MySQL pattern 仍应被拒。
+- 不连 PG、不改 DB runtime schema、不改取词/Gate2。
+
+## 涉及文件 / 函数 / 字段
+- `content_agent/business_modules/source_seed/source_context.py`
+  - `_validate_pg_evidence_pack(evidence_pack: dict) -> None`(148-192):唯一改动点。
+  - 新增一个模块级常量 `ALLOWED_SOURCE_KINDS = {"high_weight_element","high_weight_category","element_co_occurrence","category_co_occurrence","pattern_itemset","multi_source"}`。
+
+## 数据合同
+**契约保证非空(→ 必填)**
+| 字段 | 来源 |
+|---|---|
+| `pattern_source_system`(=pg_pattern_v2)/`validation_status`(=passed)/`case_id_type`(=post_id)/`source_certainty`(=db_validated) | 固定值 |
+| `source_post_id` / `pattern_execution_id` / `matched_post_ids`=`video_ids`=`case_ids` | §7 |
+| `seed_terms` / `category_bindings` / `element_bindings` | §16 + 真实 142 条样本非空 |
+| `support` / `absolute_support` | §13 |
+
+**有条件 / 可空(→ 不无条件必填)**
+| 字段 | 何时有值 |
+|---|---|
+| `itemset_ids` / `itemset_items` / `mining_config_id` | 仅来源含 `pattern_itemset` |
+| `evidence_sources` | 仅最新批次稳定存在;CFA 不无条件必填,只用于判断 multi_source 是否含 `pattern_itemset` |
+| `query_seed_points` | 可空数组(M12B 消费;M12A 不校验内容) |
+| `demand_scope` | §5(M12A 不强制) |
+
+## 实施步骤
+1. 加模块常量 `ALLOWED_SOURCE_KINDS`。
+2. 把 source_kind 别名校验从"== pattern_itemset"改为"∈ ALLOWED_SOURCE_KINDS"(沿用现有 `alias_expected_values` 取值/告警风格,值不为 None 时校验)。
+3. 从 `required_fields` 移除 `itemset_ids`/`itemset_items`/`mining_config_id`,补入 `video_ids`/`case_ids`(`pattern_execution_id`/`category_bindings`/`seed_terms`/`matched_post_ids`/`support`/`absolute_support`/`source_post_id` 已在,保留);`evidence_sources` 不列无条件必填。
+4. 加"含 itemset 时三件套必填"的条件块:`source_kind=="pattern_itemset"` 或 `evidence_sources` 含 itemset 项 → 校验三件套非空。
+5. 保留 `source_post_id ∈ matched_post_ids`。

+## Unit Test
+- `tests/test_runtime_files.py` 新增:

+# M12B 取词接 query_seed_points + 撤 element_bindings 两路 Implementation Brief
+
+## 状态
+已完成。本 brief 记录 M12 主体:CFA 首轮搜索池**主用上游 `query_seed_points`**(按 rank),**删掉吊在 `element_bindings` 上的两条词路**,`seed_terms` 作兜底。核心原则:**取词来源跟上游契约对齐——`query_seed_points` 是首轮搜索池,`element_bindings` 仅退出取词、展示/溯源不动。** 依赖 M12A 先落地(否则非 itemset 需求进不来,无真数据可验)。不连 PG、不改 DB schema、不改 Gate2 逻辑。
+
+## 目标
+1. `build_pattern_seed_pack` 白名单**新增透传 `query_seed_points`**(当前显式白名单不带它,字段会被丢)。
+2. `_run_v4` 取词候选改为:**主 `query_seed_points`(新增候选构造,按 `rank` 升序)+ 兜底 `seed_terms`**;`query_seed_points` 为空时才用 `seed_terms`。
+3. **删除** `_v4_piaoquan_point_candidates`(point_text 路)和 `_v4_category_element_candidates`(name 路)两条吊在 `element_bindings.sample_elements` 上的词路。
+4. 复用现有清洗(目的点 `_cleanup_purpose_point`、`_is_generic_query`),**不覆盖原始 `point_text`**(契约 §10 要求另存 cleaned query)。
+5. 溯源新增 `query_seed_point` 来源类型,复用现有 ref 构造函数。
+
+## 实施前证据(用于追溯)
+- `content_agent/business_modules/search_intent.py`:
+  - `:56-58` `seed_terms` 硬依赖(空则 `raise seed_terms_empty`)——契约 §11 保证非空,保留作兜底锚。
+  - `:149-202` `_run_v4`;`:159-163` 三路候选拼装(`_v4_seed_candidates` + `_v4_piaoquan_point_candidates` + `_v4_category_element_candidates`)。
+  - `:227-263` `_v4_piaoquan_point_candidates`:读 `element_bindings[].sample_elements[].point_text`(仅 目的/灵感点),目的点过 `_cleanup_purpose_point`。**已删。**
+  - `:266-297` `_v4_category_element_candidates`:读 `element_bindings[].sample_elements[].name`(不过滤 point_type,会把关键点漏进 query)。**已删。**
+  - `:205-224` `_v4_seed_candidates`:读 `seed_terms`。**保留作兜底。**
+  - 可复用:`_cleanup_purpose_point`(332)、`_is_generic_query`(600)、`_normalize_query`(590)、`_normalize_query_key`(596)、`_v4_pattern_seed_ref`(353)、`_v4_query_source_ref`(373)、`_base_query_record`(401)。
+- `content_agent/business_modules/source_seed/source_context.py:78-106` `build_pattern_seed_pack`:显式白名单逐字段搬运,**无 `query_seed_points`** → 字段在此被丢。
+- 真实现状对照:`runtime/v1/v1_run_35f4f7ccd1cc/search_queries.jsonl` 现有 `generation_method` 为 `seed_term`/`piaoquan_topic_point`/`category_leaf_element`;`pattern_seed_pack.json` 的 element_bindings 每绑定仅 1 个 sample_element(印证"2 样本"瓶颈)。
+- 上游契约 §10 `query_seed_points` 单条字段:`point_text`、`point_type∈{灵感点,目的点}`、`rank`(1..30)、`coverage_post_count`、`category_id`、`name`、`element_type` 等。
+
+## 修改范围(最小)
+1. `source_context.build_pattern_seed_pack`:白名单加一行 `"query_seed_points": evidence_pack.get("query_seed_points", [])`。
+2. `search_intent._run_v4`:
+   - 新增 `_v4_query_seed_point_candidates(pattern_seed_pack)`:遍历 `query_seed_points`(按 `rank` 升序),目的点过 `_cleanup_purpose_point`、灵感点直取,统一过 `_normalize_query` + `_is_generic_query`;`query_source_type="query_seed_point"`、`generation_method="query_seed_point"`、`query_source_fields=["query_seed_points.point_text"]`;source_ref 带 `rank`/`coverage_post_count`/`point_type`/`point_text`(原文)/`cleaned_text`/`post_id`/`category_id`。
+   - 候选拼装改为:`query_seed_points` 非空 → `_v4_query_seed_point_candidates`;为空 → `_v4_seed_candidates`(兜底)。`seed_terms` 不始终附加在 query_seed_points 后面。
+   - 删 `_v4_piaoquan_point_candidates` + `_v4_category_element_candidates` 及其调用。
+3. 溯源:`_v4_pattern_seed_ref` / `_v4_query_source_ref` 已是通用实现,新候选 dict 给齐 `query_source_type`/`generation_method`/`rank`/`source_ref` 即可复用,无需改这两个函数。
+
+## 不修改范围(禁区)
+- 不改 Gate2(`_gate2_keep`/`apply_gate2`)——M13 负责。
+- 不改 `_cleanup_purpose_point` 及其配置 `purpose_point_prefixes.v1.json`。
+- 不改 `flow_ledger_service.py` 对 `element_bindings` 的展示/溯源读取(`_demand_summary`/`_category_binding`)——element_bindings 只退出取词,展示不动。
+- 不连 PG、不改 DB runtime schema。
+
+## 涉及文件 / 函数 / 字段
+- `content_agent/business_modules/source_seed/source_context.py` → `build_pattern_seed_pack`(78-106):+1 行白名单。
+- `content_agent/business_modules/search_intent.py`:
+  - 新增 `_v4_query_seed_point_candidates(pattern_seed_pack) -> list[dict]`。
+  - 改 `_run_v4`(159-163)候选拼装。
+  - 已删 `_v4_piaoquan_point_candidates`、`_v4_category_element_candidates`、`_bindings`、`_sample_elements` 等旧私有 helper。
+
+## 数据合同
+`query_seed_points` 单条 → candidate 映射:
+| query_seed_points 字段 | candidate 用途 |
+|---|---|
+| `point_text` | query 原文;目的点经 `_cleanup_purpose_point` → `cleaned_text` 作 query;**point_text 原文存 source_ref,不覆盖** |
+| `point_type`(灵感点/目的点) | 决定是否剥前缀;存 source_ref |
+| `rank` | 候选排序(升序)+ `query_source_rank` |
+| `coverage_post_count` | 存 source_ref(可复盘热度) |
+| `category_id`/`post_id` | 存 source_ref(溯源) |
+
+## 实施步骤
+1. `build_pattern_seed_pack` 白名单加 `query_seed_points`。
+2. 写 `_v4_query_seed_point_candidates`(复用 `_cleanup_purpose_point`/`_normalize_query`/`_is_generic_query`)。
+3. 改 `_run_v4` 候选拼装为"query_seed_points 优先、seed_terms 兜底"。
+4. 删两条 element_bindings 词路 + 其私有 helper(确认无其他引用)。
+5. 跑测试,改 fixture 与断言。
+
+## 验证命令
+```bash
+cd /Users/samlee/Documents/works/ContentFindAgentNew

+# 真实库取一条带 query_seed_points 的样本,确认透传进 pattern_seed_pack(只读)
+```
+
+## Unit Test
+- `tests/test_search_intent.py`:
+  - `_seed_pack` fixture(30-73)增 `query_seed_points`(2-3 条,含目的点+灵感点+rank)。
+  - 改 `test_v4_search_intent_uses_direct_sources_without_llm_variant`:断言生成的 `search_queries` 来自 `query_seed_points`、`generation_method=="query_seed_point"`、按 rank 序、无 `piaoquan_topic_point`/`category_leaf_element`。
+  - 新增 `test_v4_falls_back_to_seed_terms_when_query_seed_points_empty`:`query_seed_points=[]` → 走 `seed_terms`。
+  - 新增 `test_purpose_point_prefix_stripped_but_point_text_preserved`:目的点 query 被剥前缀,source_ref 仍存原始 `point_text`。
+  - 去重优先级用例随候选来源更新。
+
+## Integrated Test
+- 用带 `query_seed_points` 的"高权重元素"fixture 走 mock 平台 run,确认 `search_queries.jsonl` 首轮全为 `query_seed_point` 方法、`final_output` 能溯源回 rank/coverage,`flow_ledger` 需求卡片展示无回归。
+
+## 失败归因
+- pattern_seed_pack 里没有 query_seed_points → `build_pattern_seed_pack` 白名单漏加。
+- 生成的 query 仍出现 `piaoquan_topic_point`/`category_leaf_element` → 两条词路没删干净。
+- 目的点 query 没剥前缀 → 没复用 `_cleanup_purpose_point`;若原始 point_text 被覆盖 → 违反契约 §10,source_ref 存了 cleaned 而非原文。
+- `v4_query_candidates_empty`/`v4_search_queries_empty` → query_seed_points 与 seed_terms 都空(应交 M13 兜底,不在本 brief 兜)。
+
+## sub-agent 交叉验证要点
+- **新建 subagent(本 brief 范围)**:
+  - *事实核查岗(只读)*:读契约 §10/§11 + search_intent.py:205-307,确认现状两条词路确实吊在 element_bindings;从真实 `demand_content` 库取一条带 `query_seed_points` 的样本核字段名。
+  - *技术方案岗(只读)*:确认净删两 helper + 加一 helper、复用 5 个现有纯函数、不碰 Gate2 与 flow_ledger;确认 `_v4_pattern_seed_ref`/`_v4_query_source_ref` 无需改即可承载新来源类型。
+  - *测试验收岗(只读 + 改 fixture)*:读 test_search_intent.py:30-242,核改动牵动的用例;给 `_seed_pack` 加 query_seed_points。
+- **真实读取**:代码 search_intent.py:149-307 + source_context.py:78-106;契约 §10/§11;真实 JSON runtime/v1/v1_run_35f4f7ccd1cc/{pattern_seed_pack.json,search_queries.jsonl};配置 purpose_point_prefixes.v1.json;DB demand_content(取样)。
+- 三线复核第②线(取词)以本 brief 为准回填失败归因。
+
+## 已定口径
+- 已定:`seed_terms` 是"仅 query_seed_points 空时兜底",不始终附加在 query_seed_points 之后;Gate2 清空时的兜底由 M13 使用同一批 `seed_terms` 绕过 Gate2 产出。

+# M13 Gate2 空候选兜底 Implementation Brief
+
+## 状态
+已完成。本 brief 记录 M13 最终实现:Gate2(50+ 易搜判定)把非抖音候选**全过滤后**,用 `seed_terms` 单一兜底而非 `raise`,让快手/视频号的抽象需求至少有搜索词产出、不空跑失败。核心原则:**Gate2 本身不动(仍对正常词生效);只在它清空候选时加兜底;仅快手/视频号,抖音零回归。** 依赖 M12B 的 `query_seed_points` 候选已就位。
+
+## 目标
+1. `_run_v4` 中 Gate2 过滤后候选为空时,**不再 `raise v4_search_queries_empty`**,改为用 `seed_terms` 兜底。
+2. **单一回退 = seed_terms 绕过 Gate2**:query_seed_points 被 Gate2 全否时,直接用 `seed_terms`(宽泛品类词,最稳、最易搜)生成 query 并**绕过 Gate2**,标 `gate2_fallback=True`。`seed_terms` 契约保证非空(且 `search_intent.run:56-58` 已先校验非空),故永远有词、任务永不空挂。
+3. 仅快手/视频号触发(抖音本就豁免 Gate2);Gate2 判定逻辑、阈值口径不动。
+4. **最终取舍**:不放行刚被 Gate2 判否的窄词,也不在 `search_intent.run` 里新增失败出口;最终只保留「**seed_terms 兜底**」,因为它是更宽、更稳的安全锚。
+
+## 现有证据
+- `content_agent/business_modules/search_intent.py`:
+  - `:165-166` `apply_gate2 = bool(platform) and platform != "douyin"`(仅非抖音)。
+  - `:170-197` `_admit(...)` 统一负责规范化、去重、可选 Gate2、建 query 记录。
+  - `:199` 主路 `_admit(candidates, use_gate2=apply_gate2)`。
+  - `:201-204` 主路被 Gate2 清空时,`_admit(seed_candidates, use_gate2=False, fallback=True)` 用 `seed_terms` 绕过 Gate2 兜底。
+  - `:206-207` 仍保留 `v4_search_queries_empty` 终极防线;正常 V2 契约下 `seed_terms` 非空,该分支不可达。
+  - `_gate2_keep`:只读 query 字符串,client 无 judge 方法/异常时从宽 `return True`。
+- 旧现状:抽象需求(根本观念/人物特征/叙事组织)在快手/视频号 Gate2 全否会触发 `v4_search_queries_empty`;现已由 `seed_terms` 兜底覆盖。
+
+## 与 M12B 的关系
+M12B 接 `query_seed_points` 后,Gate2 输入词从"element_bindings 样本"换成"Top30 真实点位",**词更多、过 Gate2 概率更高,空失败风险整体下降**;但极端抽象需求仍可能被清空,**M13 兜底不可省**。
+
+## 修改范围(最小:抽一个 `_admit` 内联,主路 + 兜底共用)
+`search_intent._run_v4`:
+- 先单独算 `seed_candidates = _v4_seed_candidates(...)`;`candidates = query_seed_points 候选 or seed_candidates`(保留 seed_candidates 引用供兜底)。
+- 把「规范化 → 去重 → (可选)过 Gate2 → 建记录 append」抽成一个内联闭包 `_admit(candidate_list, *, use_gate2, fallback=False)`,主路与兜底共用、零重复代码。
+- 主路:`_admit(candidates, use_gate2=apply_gate2)`。
+- 兜底:`if not search_queries: _admit(seed_candidates, use_gate2=False, fallback=True)`(绕过 Gate2、标 `gate2_fallback`)。
+- 最后保留 `if not search_queries: raise v4_search_queries_empty` 作终极防线(seed_terms 非空保证下不可达)。
+
+## 不修改范围(禁区)
+- 不改 `_gate2_keep`、`apply_gate2` 条件、Gate2 阈值/判定口径。
+- 不改抖音路径(抖音不过 Gate2,本兜底对抖音无触发)。
+- 不改 M12B 的正常取词主路(只在"清空"边界加兜底)。
+- 不改 DB schema;本兜底发生在 `search_intent.run`,不新增失败记录结构。
+
+## 涉及文件 / 函数 / 字段
+- `content_agent/business_modules/search_intent.py`
+  - `_run_v4`(149-210):新增 `seed_candidates` 引用、内联 `_admit(...)`、主路 + seed_terms 兜底共用建行逻辑。
+  - 候选 dict 标记位 `gate2_fallback`(进 source_ref / query 记录,便于复盘)。
+
+## 数据合同
+兜底 query 仍走原 `search_queries.jsonl` 合同;仅在 `query_source_refs[].source_ref` 增加 `gate2_fallback=true`。不新增 DB 列、不新增失败记录结构。
+
+## 实施步骤
+1. 已加 `seed_candidates = _v4_seed_candidates(...)`,供主路为空和 Gate2 清空时复用。
+2. 已抽内联 `_admit(candidate_list, *, use_gate2, fallback=False)`,主路与兜底共用建行代码。
+3. 已在主路后增加 `if not search_queries: _admit(seed_candidates, use_gate2=False, fallback=True)`。
+4. 已保留最终 `v4_search_queries_empty` 防线。
+5. 已补测试覆盖。
+
+## 验证命令
+```bash
+cd /Users/samlee/Documents/works/ContentFindAgentNew
+.venv/bin/python -m pytest tests/test_gate2_query_50plus.py tests/test_search_intent.py -q
+```
+
+## Unit Test
+- `tests/test_gate2_query_50plus.py`:
+  - `test_gate2_all_rejected_falls_back_to_seed_terms_for_non_douyin`:`FakeQueryVariantClient.judge_query_fifty_plus` 恒 False、platform=kuaishou → 不 raise,产出 `seed_terms`,标 `gate2_fallback=true`。
+  - `test_gate2_fallback_preserves_raw_payload_marker`:兜底标记写入 raw payload,便于复盘。
+  - `test_douyin_unaffected_by_gate2_fallback`:platform=douyin → 不进 Gate2、不进兜底(零回归)。
+
+## Integrated Test
+- 快手/视频号平台 + "Gate2 全否"mock 走完整 run,确认 run 不在 plan_queries 挂掉、能继续到后续节点。
+
+## 失败归因
+- 仍 `v4_search_queries_empty` → 回退分支没在 raise 之前插入,或 `seed_terms` 为空且上游契约失守。
+- 抖音也走了兜底 → 误把兜底放在 `apply_gate2` 判断之外。
+- 下游 `search_platform` 对空 search_queries 崩 → `seed_terms` 兜底未产出,应先查 source evidence 的 `seed_terms`。
+
+## sub-agent 交叉验证要点
+- **新建 subagent(本 brief 范围)**:
+  - *事实核查岗(只读)*:读 search_intent.py:149-210,确认 Gate2 仅非抖音、清空后 seed_terms 兜底。
+  - *技术方案岗(只读)*:确认只在 raise 前插 seed_terms 兜底、Gate2 本身不动、复用 `_v4_seed_candidates`,无新 ErrorCode/DB 字段。
+  - *测试验收岗(只读 + 造 mock)*:用 `FakeQueryVariantClient` 令 `judge_query_fifty_plus` 恒 False 验证 seed_terms 兜底 + 抖音零回归。
+- **真实读取**:代码 search_intent.py:149-210;测试 test_gate2_query_50plus.py + p1_helpers.py(`FakeQueryVariantClient`)。
