panda 2befd44430 Merge remote v4/v5 features (multimodal chat input, layered generation, annotation detection) with local v3 features (dialog file upload, XLSX support, session fix) 
Key resolutions:
- agent/nodes.py: Merged session_id exclusion fix with new persistable fields (ocr_extraction_result, annotation_result, layout_schema, ocr_elements)
- app.py: Adopted st-multimodal-chatinput for unified paste/drop/upload, removed custom JS paste bridge
- backend/file_parser.py: Kept local XLSX parser, added remote XLS/DOC parsers
- CLAUDE.md + CODE_GUIDE.md: Merged documentation from both branches

panda 43a0542a11 feat: layered precise generation for A4 report images 
3-phase pipeline to solve LLM prompt overflow from too many OCR elements:
Phase 1 (generate_skeleton): compressed layout schema → skeleton JRXML
Phase 2 (refine_layout): sampled coordinates → pixel-level position tuning
Phase 3 (map_fields): OCR field names → replace $F{field_N} placeholders

Only triggered when layout_schema.total_rows > 0 on initial_generation intent.
Text requests and all other intents are unaffected (zero behavior change).

panda 9bb011e429 feat: v4 multimodal chat input, multi-format support, and annotation detection 
- Replace st.chat_input with st-multimodal-chatinput (Ctrl+V paste, drag-drop, file button)
- Extract _process_uploaded_file() shared handler (eliminates ~70 duplicated lines)
- Add XLSX (openpyxl), XLS (xlrd), DOC (olefile) parsers to file_parser.py
- Add backend/annotation_detector.py: circle detection (HoughCircles) + arrow detection (HoughLinesP clustering) + OCR correlation + LLM context formatting
- Add annotation_result field to AgentState with session persistence
- Wire annotation detection into process_input and _format_ocr_context
- Add 11 new tests: 7 annotation detector + 4 multi-format parser
- Update all docs: CLAUDE.md, README.md, CODE_GUIDE.md, ROADMAP.md

panda 87ead4fa6a feat: 对话区域文件上传(粘贴/拖拽) + XLSX支持 + 会话切换无限循环修复 
- 对话区域: st.file_uploader + 全局 paste/drop 事件监听 + sessionStorage 桥接
- 文件预览芯片: 上传后显示在对话区域，可逐文件移除
- OCR 双层解析全面接入: file_parser(文字) + ocr_extractor(字段提取)
- XLSX 解析: openpyxl 逐工作表/逐行读取
- 修复: create_session 强制写入 agent_state.session_id
- 修复: load_session_node 不再从磁盘覆盖 session_id
- 修复: 切换会话 _last_switched_to 哨兵防止无限 rerun

panda da79640259 fix: OCR字段提取集成修复 + 会话切换无限循环修复 + 一键启动脚本 
- process_input 传入17个默认中文字段（修复空列表导致零字段提取）
- OCR提取结果自动注入 LLM 上下文
- save_session_node/load_session_node 持久化 session_id（修复切换会话无限 rerun）
- app.py 会话切换后显式设置 session_id（纵深防御）
- 新增 start.bat / stop.bat 一键启动/停止脚本
- 更新 CLAUDE.md + CODE_GUIDE.md 文档

panda 067880bf2e feat: 添加结构化日志系统，更新LLM配置与全部文档 
新增:
- backend/logger.py — 集中日志模块 (JSON格式 + trace_id + 独立llm.log)
- @log_node / @_log_route 装饰器覆盖17个节点和8个路由

改进:
- backend/llm.py — _LLMLoggingWrapper 自动记录LLM输入输出
- backend/llm.py — API Key优先读ANTHROPIC_API_KEY，模型名改为MiniMax-M2.7
- backend/llm.py — get_llm() 新增caller参数标识调用来源
- backend/validation.py — 新增验证结果/连接失败日志
- backend/session.py — 新增会话创建/删除日志
- app.py — 新增用户交互日志 (输入/执行/异常/会话操作)
- app.py — 提前导入torchvision抑制transformers懒加载报错
- .env.example — 新增LOG_DIR/LOG_LEVEL/ANTHROPIC_API_KEY等配置项
- .gitignore — 新增logs/和db/忽略规则

文档:
- ROADMAP.md — 新增阶段四: 可观测性
- README.md — 补充日志架构/LLM配置/项目结构
- CLAUDE.md — 同步最新配置/日志/MAX_RETRY(3)
- CODE_GUIDE.md — 新增第15章日志系统，更新架构图/LLM/配置

panda 6467fd4ae5 feat: v3 robustness upgrade — EasyOCR, failure recovery, minimum content check 
- OCR: EasyOCR (primary, ch_sim+en) with PaddleOCR fallback for Windows compatibility
- Validation: _check_minimum_content() rejects empty-shell JRXML (no band/textField)
- Retry: MAX_RETRY 3→5, exhaustion records pending_failure_context for next-turn auto-injection
- Finalize: only saves jrxml_versions on pass, preserves last good final_jrxml on fail
- Extract JRXML: improved empty markdown block handling and XML fragment fallback
- UI: real-time node progress via placeholder updates, initial "analyzing" feedback
- UI: use agent_state (full) instead of node_state (partial) for summary card routing
- UI: unknown template_type now gives LLM meaningful image context instead of metadata
- Docs: updated CLAUDE.md and CODE_GUIDE.md to reflect all v3 changes
