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).	2026-05-21 08:34:32 +08:00
panda	70614dff5e	feat: comprehensive v2 upgrade — streaming, error KB, file upload, layout analysis ... Major changes: - Streaming: LLM统一 _BaseLLM 接口 (invoke + stream), generate/modify/correct 节点使用 get_stream_writer() 实现逐字输出, UI 节点平铺展开自动折叠 - Prompt外部化: 7个prompt拆分到 prompts/*.md, loader.py 支持热重载 - 错误自增长: backend/error_kb.py — 指纹去重 + ChromaDB持久化, correct_jrxml→validate 通过时自动入库, retrieve同时搜索错误KB - 文件上传: backend/file_parser.py — PDF/DOCX/图片/文本解析, 侧边栏多文件上传, 文本自动注入下一条消息 - A4模板识别: backend/layout_analyzer.py — 三种模式(完整A4/行片段修改/行片段新建), PaddleOCR元素提取 + 行分组 + JRXML section匹配 - 会话历史下载: jrxml_versions版本追踪 + 侧边栏历史版本下载按钮 - 预览修复: route_after_save跳过预览/导出意图的验证循环 - Ctrl+C修复: JS注入拦截Streamlit裸c键清缓存 Docs: CLAUDE.md (完整项目文档), ROADMAP.md (改进路线图) Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>	2026-05-19 15:02:53 +08:00
