Server / Hosted 0.19.0 streamlines the model context used to understand conversations and maintain the Work DAG. Client / Plugins are also available at 0.19.0, with the same behavior as 0.18.6. npm coconet@0.19.0 is published. Upgrade with npm install --global coconet@0.19.0 and start a new Agent session to load the matching Plugin.
- Simplifies seven input paths: Work Extraction, Graph Action, History Extraction, Bootstrap Graph, History Patch, Library Checkpoint and Library Tags.
- Removes unnecessary session metadata from model requests while retaining decision references, inherited-context markers and truncation indicators where needed. Internal identity, version and concurrency checks remain in place.
- Counts compact model input toward evidence budgets, preserves recent requests and cumulative outcomes, and separates historical overviews from fixed Library checkpoint summaries.
- Preserves accounts, projects, Sessions, existing graph nodes and Library entries. No metadata migration, data reset or automatic bulk regeneration is required.
Validation: the full repository checks passed; existing copied-history and bounded real-model checks were reviewed. Linux amd64 and arm64 binaries and archives were each built twice with identical hashes. The exact amd64 release binary passed an isolated two-version upload, extraction and DAG-update smoke test on the Hosted machine. Hosted health, served assets and configuration continuity were checked after deployment.
Model summaries remain interpretations of available conversation evidence, not independent execution verification. Very large graph candidate selection and occasional over-splitting of repair stages remain outside this release.
Server / Hosted 0.19.0 统一精简会话理解与 Work DAG 维护的模型上下文。Client / 双 Plugin 同步提供 0.19.0，功能与 0.18.6 相同；npm coconet@0.19.0 已发布。运行 npm install --global coconet@0.19.0 更新，再开启新 Agent 会话加载对应 Plugin。现有 0.18.6 客户端仍兼容。
- 完成七类输入的梳理：普通工作提取、图动作、历史提取、首次构图、历史补图、Library 检查点和主题标签。
- 移除模型决策不需要的会话元数据；按需保留节点引用、继承关系和截断提示。服务端内部身份、版本与并发校验保留。
- 证据预算按精简输入计算，保留近期请求与累计成果，并区分历史概括与固定时点摘要。
- 保留账号、项目、会话、DAG 和 Library；无需数据迁移或重置，也不批量重算已有结果。
完整仓库检查通过，历史会话副本及有预算限制的真实模型验证已完成。两个 Linux 架构的程序和压缩包重复构建哈希一致；发布程序通过独立环境的两轮上传、提取和 DAG 更新测试，上线后检查服务、静态资源及配置连续性。
摘要仍依赖可见对话证据，不能代替执行结果验证；超大图候选筛选和连续返修偶发过度拆分仍是后续改进项。
Client 0.19.0 is a version-alignment release. The existing Server assets, SHA256SUMS, server-release.json and tag are retained. Additional client archives use CLIENT-SHA256SUMS and client-release.json.
客户端 0.19.0 仅对齐版本号，现有安装、连接和会话可保留。已发布的 Server 制品、原校验清单和 Tag 保持；新增客户端制品使用独立的 CLIENT-SHA256SUMS 与 client-release.json。
