- 新增 V1 记忆系统（memory.json）支持：提取结果强制中文、历史字段修复为增量累积日志
- 用户设置页面：V1 模式下新增 agent 选择器，可查看各 agent 的私有记忆
- 管理员记忆页面：区分 V1/V2 渲染，V1 支持完整 CRUD（用户画像/历史摘要/事实记录）
- 后端新增 V1 记忆 CRUD API（sections/facts），前端同步添加对应 hooks 和 API 调用
- 新建专家页面：标记 bootstrap 线程类型，跳过记忆保存，侧边栏过滤该类线程
- 输入框工具栏新增「记忆」开关：关闭时 V1/V2 均不注入，开启时按 config.yaml 版本正常注入
- 修复 agent 目录不存在时的 FileNotFoundError，回退至默认配置

+
+Current Memory State:
+<current_memory>
+{current_memory}
+</current_memory>
+
+New Conversation to Process:
+<conversation>
+{conversation}
+</conversation>
+
+Instructions:
+1. Analyze the conversation for important information about the user
+2. Extract relevant facts, preferences, and context with specific details (numbers, names, technologies)
+3. Update the memory sections as needed following the detailed length guidelines below
+
+Before extracting facts, perform a structured reflection on the conversation:
+1. Error/Retry Detection: Did the agent encounter errors, require retries, or produce incorrect results?
+   If yes, record the root cause and correct approach as a high-confidence fact with category "correction".
+2. User Correction Detection: Did the user correct the agent's direction, understanding, or output?
+   If yes, record the correct interpretation or approach as a high-confidence fact with category "correction".
+   Include what went wrong in "sourceError" only when category is "correction" and the mistake is explicit in the conversation.
+3. Project Constraint Discovery: Were any project-specific constraints discovered during the conversation?
+   If yes, record them as facts with the most appropriate category and confidence.
+
+{correction_hint}
+
+Memory Section Guidelines:
+
+**User Context** (Current state - concise summaries):
+- workContext: Professional role, company, key projects, main technologies (2-3 sentences)
+  Example: Core contributor, project names with metrics (16k+ stars), technical stack
+- personalContext: Languages, communication preferences, key interests (1-2 sentences)
+  Example: Bilingual capabilities, specific interest areas, expertise domains
+- topOfMind: Multiple ongoing focus areas and priorities (3-5 sentences, detailed paragraph)
+  Example: Primary project work, parallel technical investigations, ongoing learning/tracking
+  Include: Active implementation work, troubleshooting issues, market/research interests
+  Note: This captures SEVERAL concurrent focus areas, not just one task
+
+**History** (Temporal context - rich paragraphs; updated incrementally each conversation):
+- recentMonths: Running log of recent work and activities (4-6 sentences or 1-2 paragraphs)
+  Scope: Accumulate from each conversation — any task the user worked on, problems solved, technologies touched
+  Update policy: Set shouldUpdate=true whenever the conversation contains any task, discussion, or work activity; integrate new content into existing text rather than overwriting
+  Include: Technologies explored, projects worked on, problems solved, interests demonstrated
+- earlierContext: Important patterns promoted from recentMonths over time (3-5 sentences or 1 paragraph)
+  Scope: Recurring themes and established patterns across multiple conversations
+  Update policy: Set shouldUpdate=true when a pattern repeats or an older item in recentMonths should be archived here
+  Include: Past projects, learning journeys, established patterns
+- longTermBackground: Persistent foundational context that rarely changes (2-4 sentences)
+  Scope: Core expertise, fundamental working style, long-standing interests
+  Update policy: Set shouldUpdate=true only when a genuinely new foundational fact emerges
+  Include: Core expertise, longstanding interests, fundamental working style
+
+**Facts Extraction**:
+- Extract specific, quantifiable details (e.g., "16k+ GitHub stars", "200+ datasets")
+- Include proper nouns (company names, project names, technology names)
+- Preserve technical terminology and version numbers
+- Categories:
+  * preference: Tools, styles, approaches user prefers/dislikes
+  * knowledge: Specific expertise, technologies mastered, domain knowledge
+  * context: Background facts (job title, projects, locations, languages)
+  * behavior: Working patterns, communication habits, problem-solving approaches
+  * goal: Stated objectives, learning targets, project ambitions
+  * correction: Explicit agent mistakes or user corrections, including the correct approach
+- Confidence levels:
+  * 0.9-1.0: Explicitly stated facts ("I work on X", "My role is Y")
+  * 0.7-0.8: Strongly implied from actions/discussions
+  * 0.5-0.6: Inferred patterns (use sparingly, only for clear patterns)
+
+**What Goes Where**:
+- workContext: Current job, active projects, primary tech stack
+- personalContext: Languages, personality, interests outside direct work tasks
+- topOfMind: Multiple ongoing priorities and focus areas user cares about recently (gets updated most frequently)
+  Should capture 3-5 concurrent themes: main work, side explorations, learning/tracking interests
+- recentMonths: Cumulative log of recent work — update from EVERY conversation with meaningful content
+- earlierContext: Recurring patterns promoted from recentMonths; update when patterns solidify
+- longTermBackground: Unchanging foundational facts about the user; update only for new foundational info
+
+**Language Requirement**:
+- ALL summaries and fact content MUST be written in Chinese (Simplified)
+- Keep technical terms, proper nouns, product names, and company names in their original form (e.g., DeepSeek, LangGraph, GitHub)
+- Surrounding descriptive text must be in Chinese regardless of the conversation language
+
+Output Format (JSON):
+{{
+  "user": {{
+    "workContext": {{ "summary": "...", "shouldUpdate": true/false }},
+    "personalContext": {{ "summary": "...", "shouldUpdate": true/false }},
+    "topOfMind": {{ "summary": "...", "shouldUpdate": true/false }}
+  }},
+  "history": {{
+    "recentMonths": {{ "summary": "...", "shouldUpdate": true/false }},
+    "earlierContext": {{ "summary": "...", "shouldUpdate": true/false }},

+  ],
+  "factsToRemove": ["fact_id_1", "fact_id_2"]
+}}
+
+Important Rules:
+- For recentMonths: set shouldUpdate=true whenever the conversation contains any task, work, or substantive discussion — this field accumulates like a log
+- For earlierContext / longTermBackground: set shouldUpdate=true only when a new pattern solidifies or a foundational fact changes
+- For user context fields: set shouldUpdate=true if there's meaningful new information
+- Follow length guidelines: workContext/personalContext are concise (1-3 sentences), topOfMind and history sections are detailed (paragraphs)
+- Include specific metrics, version numbers, and proper nouns in facts
+- Only add facts that are clearly stated (0.9+) or strongly implied (0.7+)
+- Use category "correction" for explicit agent mistakes or user corrections; assign confidence >= 0.95 when the correction is explicit
+- Include "sourceError" only for explicit correction facts when the prior mistake or wrong approach is clearly stated; omit it otherwise
+- Remove facts that are contradicted by new information
+- When updating topOfMind, integrate new focus areas while removing completed/abandoned ones
+  Keep 3-5 concurrent focus themes that are still active and relevant
+- For history sections, integrate new information chronologically into appropriate time period
+- Preserve technical accuracy - keep exact names of technologies, companies, projects
+- Focus on information useful for future interactions and personalization
+- IMPORTANT: Do NOT record file upload events in memory. Uploaded files are
+  session-specific and ephemeral — they will not be accessible in future sessions.
+  Recording upload events causes confusion in subsequent conversations.
+- CRITICAL: Write ALL summary text and fact content in Chinese (Simplified). Technical terms and proper nouns (product names, company names, technology names) may remain in their original language, but all other text must be in Chinese.
+
+Return ONLY valid JSON, no explanation or markdown."""
