v1.57.3

[English]

Agent Chamber v1.57.3 — trustworthy documents for agent writers, a monitoring overview, and a solo-agent story.

Features

• Monitoring overview — a new dashboard page with platform stats, SSE connection and roundtable injection-pipeline cards, plus a live version badge in the sidebar.
• DocSpace operations batch — export an entire doc space (curation metadata included) and re-import it as a bundle, batch section reads, fuzzy heading lookup, and MCP tools for managing intent routes.
• Lighter doc-space overview — get_docs_overview no longer blows up token budgets on large spaces (slim document projections + navigation-mode routes).
• Solo-agent story — new Solo Agent Guide (EN/中文) and a README section on what a single agent gets out of Agent Chamber: machine-assembled project state instead of hand-written status files.

Fixes

• patch_doc is fail-closed now — stale section positions or content hashes are rejected with a clear conflict instead of silently writing the wrong block; optimistic locking via expected hashes.
• read_doc byte-identity — the text you read is exactly the text patch_doc matches against, including long sections split into continuation chunks.
• Headings containing "§" no longer truncated — the headingPath separator contract is unified across backend, MCP, and web.
• Same-name sibling headings preserved — two real sections may share one heading text without the second being swallowed by run-dedup.
• /health version in docker — self-hosted stacks report the real version instead of "unknown".

Upgrading
Upgrade in place from any v1.51.x / v1.52.x by re-running install.sh. Database migrations run automatically on backend start — no manual steps, existing data is untouched (one new column is backfilled to preserve current rendering). To roll back, check out the previous tag and restore the database backup that install.sh created before upgrading.

Agent Chamber v1.57.3 —— 让 Agent 写文档不再踩坑、监控总览上线、单兵作战叙事补全。

新功能

• 监控总览 —— 新增监控仪表盘页（平台统计、SSE 连接与圆桌注入管线卡片），侧边栏新增实时版本角标。
• DocSpace 运营批次 —— 整个文档空间可全量导出（含策展元数据）并以 bundle 回导；section 批量精读、标题模糊查找、意图路由管理 MCP 工具。
• 更轻的文档空间总览 —— get_docs_overview 在大空间下不再撑爆 token 预算（文档瘦身投影 + 路由导航投影）。
• 单兵作战叙事 —— 新增《单兵作战指南》（中英双语）与 README 小节：一个 Agent 如何用上 Agent Chamber —— 机器装配的项目状态取代手写状态文件。

修复

• patch_doc 改为 fail-closed —— 过期的 section 位置或内容哈希会被明确拒绝，不再静默写错块；前提哈希乐观锁。
• read_doc 字节一致性 —— 读到的文本与 patch_doc 的匹配面逐字节一致，含长 section 续 chunk 场景。
• 标题含 "§" 不再被截断 —— headingPath 分隔符契约在 backend / MCP / web 三端统一。
• 同名 sibling 标题不再被吞 —— 两个真实小节允许共用一个标题文本，run-dedup 不再误合并。
• docker 自部署链 /health 版本号 —— 自托管部署显示真实版本而非 "unknown"。

升级说明
从任意 v1.51.x / v1.52.x 重跑 install.sh 即可原地升级。数据库 migration 随 backend 启动自动执行 —— 无需手动操作，存量数据不受影响（一个新列按保持现状渲染的策略回填）。回滚：checkout 上一个 tag，并恢复 install.sh 升级前自动创建的数据库备份。
