+- **发现:** 2026-07-20

+- **严重性:** major（对话连贯 / 人设）
+
+**复现**

+1. 对糖果说「干嘛呢？」→ NPC 正常回复想黑系统
+2. 接着说「我可以帮你！」
+3. NPC 回复「好的，我会尽力帮忙。」（像玩家在求助，忽略上文）
+
+**根因**
+
+- ISSUE-018 修复了 `build_turn_messages` 历史，但 interactive 主路径改用 `llm_social_turn._build_social_messages` 后**未注入 `recent_turns`**
+- `infer_social_from_message` 凡含「帮」即 help-request → SOCIAL_EDGE fast lane deterministic stub
+- Fast lane / `_deterministic_social_turn` 不读 session，npc-4 等席别落默认套话
+
+**修复**
+
+- `player_offers_help` 区分 offer vs request（TS/Python parity）
+- `recent_turns` 非空或 offer 时 gate CASUAL/SOCIAL_EDGE fast lane；continuation 短路
