 完成报告先进入私有持久outbox，有界重试并幂等确认；执行完成与集成验收分别记录。通知要求每目标最多一条未处理，其余保留并合并。当前支持execution_notification_targets显式映射：依据正式任务session_id，将任务相关事件和ETA优先交执行者；未映射事项及系统事件交配置的唯一副主控，决策直达总控。目标变更须保留旧回执并对账迁移，不盲重放积压。宿主原生队列总数与取消能力未知时如实说明，不能声称已清空。配置、实现范围与验收要求见[运行接入](references/operations.md#一层副主控的路由与可靠上报)。

+咨询桥接按真实待发或在途消息分配，不因绑定存在就长期占位。空闲释放前核对worker、待交付回执和未知执行；只停止自有桥接，不终止模型writer。保留并发上限，按持久等待时间公平轮转；人类咨询及决策优先，普通事项达到老化窗口后按先到顺序提升，不能永久饥饿。断网时保留原消息、幂等键和回执，恢复后续传；可能已执行的输入先查原会话和关联回复，禁止换ID盲重放。具体调度与恢复见运行指南。
+
+页面按证据区分已保存、排队、宿主送达、真实处理、关联回复和受阻。保存成功不等于送达，模型回复不等于业务验收；未知结果明确待核对。普通成功阶段收起保留可查，等待和受阻短提示，不堆叠技术回执。
+
 执行负责人完成工作后，先把带稳定报告ID、任务版本、证据和检查结果的完成报告保存到私有持久 outbox，再按有界退避重试交付；服务落库回执确认后才标已上报。重试复用同一幂等ID，不重新执行业务操作；结果未知先对账，达到上限保留待核查状态，交副主控处理。对话中的“完成”不能替代可靠落库，执行完成也不等于集成验收完成；集成负责人另核对源产物、接口和验收证据。
 
 通知按目标背压：同一目标最多一条未处理通知，后续事件保留在持久队列并按关联ID合并。排队accepted不等于处理完成，需核对真实目标turn/处理回执才能释放名额；未知结果不得通过换ID或清本地记录绕过。应用outbox、已知inflight与宿主原生队列分别记账；无法读取宿主总数或确认取消时，必须写未知/不支持，不能宣称原生队列已清空。现有机制与限制见运行指南。

+决策只来自真实需求，卡片包含简介及关联任务。用户可选择方案或自由填写意见，至少一项有效；提交保留当时版本与选项快照，进入pending_review。主控核对真实提交的影响和执行计划后接受为accepted或退回needs_reconsideration；接受不等于系统操作授权。内容实质变化保留旧快照并要求按新revision重新确认，旧记录不能静默覆盖。关联新决策显式登记来源，不自动编造。

+
+主控检查后记录结论、交接及证据才完成；完成后由获授权总控调用宿主真实归档工具，再保存回执，服务记录不冒充归档操作。隔离测试不能代替真实会话绑定与往返，尚未验证必须明示；没有真实待决定事项时不得为验收创建生产决策或会话。
+
+已有专门人类入口时，主控、副主控和执行者不得直接向用户提问；问题、待选择、待授权及关键结论定向交唯一入口，由入口理解并与人类交互，再整理给主控，不经过底层事件队列。需选项先建真实决策卡，入口简短链接。决策页内嵌咨询只回答该决策范围问题，不另设一般项目入口；人类决定和审批仍走决策卡与唯一入口。
+
+## 网页草稿持久边界
+
+沟通输入、决策意见与选择、决策咨询输入应在浏览器本地持久保存，按实例、目标会话、决策与内容版本隔离；退出页面、刷新及重新登录后恢复同范围草稿。草稿不是已提交事实，不上传草稿，不将token写入草稿记录。仅收到成功确认后清除对应提交的草稿，或由用户明确清除单项；失败和结果未知保留正文与幂等重试信息，禁止自动重发。内容版本变化保留旧稿供明确重确认，不能静默覆盖新版本或沿用旧选择作为批准。
+
+本地存储不可用时如实提示，不能宣称已保存；本地浏览器数据被清理、设备更换或旧版未持久化的已丢稿不承诺恢复。已有唯一人类入口时，相关限制与所需用户操作仍由该入口沟通。
+
+功能修复不得擅自增加按钮和解释性文案。草稿自动保存、恢复及成功后清除在后台完成，不放常驻存储说明、清除草稿按钮或冗余成功提示；仅真正阻止操作并需要人类处理的错误或版本冲突显示最短必要提示。移除控件不删除已有草稿或改变已提交决定。

+# 独立决策会话接入
+
+本流程由主控执行。仅对真实待决策事项建立卡片与宿主会话；隔离 API 测试不证明真实会话、模型往返或归档已通过。
+
+1. 在正式看板创建有依据的决策，关联唯一任务，写明简介、完整背景、全部选项和影响。保存创建回执。没有真实事项时不要为验收制造生产决策。
+2. 先为本决策规划本机私有有限配置路径。读取宿主项目/会话清单，确认没有既有绑定，再用宿主正式创建工具建立独立真实会话。使用 `assets/decision-consultation-prompt.txt` 生成角色说明，替换真实决策 ID 与计划配置路径；不指定未获人类选择的模型。配置尚未准备时，初始化只等待接入，不读取普通控制凭据或生成演示回复。保存宿主返回的真实 thread ID、执行主机和工作目录。
+3. 注册 `role=decision`、`wp=<decision_id>` 的看板 session；核对宿主真实会话身份后调用 `bind-session`。一个决策只绑定一个真实会话，不复用入口或执行会话。保存绑定回执；数据库中的占位 ID 不是宿主创建证据。
+4. 仅绑定后，使用普通控制连接调用该决策的 `consultation-credential`，把返回 token 直接写入本机私有文件，不打印、不传给聊天、不存源码。写一个私有配置，形如 `{"decision_id":"<真实ID>","control":{"url":"http://<已授权看板域名>:8796","token_file":"<本机私有token路径>"}}`。该配置只给对应咨询会话；普通控制连接和模型认证留在执行器，不分发给会话。签发响应未知时先核查既有私有回执和文件，不反复轮换已交付凭据。
+5. 本机桥接私有配置可启用 `decision_fleet: {"enabled":true,"runtime_root":"<私有目录>","max_active":3}`。fleet 从正式 bindings 接口读取已绑定会话，在其实际目录运行原有 worker/mirror。它不创建模型会话、不归档、不切模型，超过上限保留等待。每个会话有独立租期、幂等回执与未知结果保护；不能重复启动第二套执行器或抢 writer 锁。
+6. 验证决策详情内的一条真实咨询进入该 thread，并核对同一 thread 的真实回复回到本决策。再验证事实核实请求、主控保存答复及绑定会话收到答复；不把投递 ACK 当实际处理。咨询内容通过既有历史投影展示，内部工具和原始通知不混进聊天。
+7. 用户提交只进入待检查。主控读取提交时的不可变快照，核实适用范围与风险，再记录接受或重议、效果与执行规划；主控检查结论由唯一人类入口简短解释并链接卡片。权限相关动作另核实真实人类授权，不能仅靠网页来源、咨询建议或 accepted 状态执行。
+8. 完成后先保存检查结论、实际完成证据和交接。核对咨询输入没有 queued/claimed/uncertain，且私有 worker 不存在 inflight、pending_completion 或 needs_reconciliation。然后用宿主受支持归档工具归档真实 thread，成功后才保存 archive-receipt。仅写归档字段不是宿主归档；归档失败保留待归档，不抹去记录或删除会话。
+
+完成并归档后，卡片、版本、提交快照、检查结论和聊天只读保留。fleet 只停止自身桥接进程，不杀模型 writer；有未知执行状态时保留证据等待对账，不能盲重放。
+
+有限 API 凭据约束的是服务端接口，不是宿主操作系统沙箱。咨询会话的代码/系统边界同时依赖其角色约束及宿主权限；不要声称已提供未实际配置的硬隔离。
+
+决策通知外发前先调用 `/api/decision-notifications/submitting` 持久标记，再保存本机 submitting 状态并调用宿主队列。标记调用失败可幂等重试，但不发送模型输入；真实队列发送未知时先对账、不盲重发。服务端只取消未开始/未确认的过时通知，已开始或未知发送保留审计。

+页面升级与旧草稿：状态同步不会替换已加载的网页代码。服务公布当前前端入口文件，版本变化只提示，不自动整页重载或重发。新版草稿保存机制应在同浏览器、同实例及对应会话/决策范围内恢复输入与重试信息；存储失败或旧页面尚未支持持久保存时明确提示先自行保留内容再重载，不能把复制作为正常持久化方案。旧提交缺expected_revision仍拒绝写入，不猜版本；核对response/history和咨询消息确认落库结果，再由人类入口说明操作。旧版已丢稿无服务证据不得承诺恢复。
+
+## 本地草稿实际存储契约
+
+同源localStorage使用workbench-draft-v1:前缀加JSON数组作用域。沟通为[instance_id, communication, 入口session]；决策为[instance_id, decision, decision_id, revision]；咨询为[instance_id, consultation, decision_id, session_id或unbound, revision]。不包含token，不上传未提交正文。实例或有效版本尚未就绪时禁发，不猜版本；新浏览器、不同源/实例或清理浏览器数据不保证恢复。重新登录不以token作为草稿身份，因此同浏览器同范围可恢复，并非按用户账号隔离。
+
+每次输入写入，POST前先持久保存attempt幂等信息；失败或结果未知保留，刷新后可由用户明确重试，不自动发送。读取/保存失败显示具体风险并阻止发送，可重试保存；清除失败提示旧稿可能残留，不应重复提交。成功只清对应当前版本草稿，比较已存值防迟到响应删掉随后编辑；咨询成功不清决策选择。只确认接口成功不表示模型已回复或业务验收完成。
+
+当前版本无记录时可读取同作用域最近旧版本草稿，保留旧revision，须用户明确重确认，决策旧选项清除后重新选择/检查意见。已完成决策的残留草稿只读，不自动重交。页面不提供额外清草稿按钮，不因切页、隐藏控件或版本提示删除旧稿；确认成功仍用原有比较清除保护。绑定session变化属于不同范围，不承诺自动跨绑定迁移。
