本页包含已接线核心流程及可选扩展；具体子能力必须按设备、平台与用户授权求交集。参见支持范围、场景索引和命令手册。图中S编号只用于本文定位，不放入实际JSON。

前置条件

设备主动呼叫通过sessionCreate.targetParty指定授权用户或设备；不会仅凭可见设备ID得到拨打权限。展示取消、保持、转接与转人工子流程，媒体建立复用S06。

设备→用户、设备→设备、应用→设备使用同一呼叫组和独立端会话腿。已忙可拒绝或waiting，不自动hold旧通话；用户接听新来电才先hold旧通话并切焦点。挂断新通话也要按S18规则恢复旧通话。cancel仅取消尚未接通的组，若接听已先提交则返回409，调用者明确再hangup。这是控制请求失败，不是原呼叫失败：原会话腿、忙线所有权与媒体不因该拒绝被关闭；失败字段及原token去重顺序见callState。

D/D2是不同设备参与端，A是应用端，P是平台和媒体节点。各端分别使用鉴权Topic/登录态，不能冒用另一端身份。基础会话与媒体协商见S01/S06，复用时保留本场景sessionId并独立分配密钥和token。

正常设备转接中，D是转接发起方，成功后只结束D原会话腿；D2保留原会话腿与媒体端点，最终与新候选D3通话。候选真正接听、ICE/DTLS连通及匹配mediaState前，D↔D2原媒体不切换；拒接、候选取消或超时只失败本次操作，保留原呼叫、忙线和媒体。此语义不套用于下方独立AI转人工分支。

AI转人工示例中，原D的s-ai始终属于AI；s13-human-local是D的新人工会话腿，s13-human仅属于D3，二者同属s13-ai-human-group。这些由平台在原意图账本中一次分配，并通过escalate条件关联字段告知D，不能由设备猜测或自报。原AI能力与双方人际能力必须真实同时支持；当前独立AI/人际客户端不因此设计自动具备组合能力。

第三屏障还要求D已实际声明microphone/speaker整组焦点能力、原AI确有对应完整租约和唯一共享采集/播放驱动。普通独立桌面末端的speaker/display能力不能替代整组能力；本协议已新增C++共享宿主、HumanVoice适配及浏览器独立输入/输出门控，但真实组合验收仍未完成，不能把单测回执当实际交接。未声明或未取得完整资源时明确拒绝，不发虚构整组回执。原租约、原用户意图、全局revision和两腿关联必须在平台及设备可信账本存在；有Peer不等于有采集授权，priority=call也不自动抢原租约。

下方AI示例假设s-ai已消耗eventSeq至100、其真实整组租约为ai-conversation-focus、设备全局资源修订号为10；这些须来自原已确认账本与实际驱动，不能由设备猜测或初始化补造。成功分支M65消耗旧AI事件101，M46为102、M47为103；新人际本端腿M67为事件2、M55为3。拒接分支未执行M65时M58仍为101；若已发送M65则M58须用下一实际事件号，恢复分支已发送M70时须大于102，不重置共享水位。失败与成功分支互斥，不把所有示例串为一次执行。绝对到期、SDP和资源标识均为占位示例，不是可连接凭据；实际邀请截止为首次45秒候选期限、原会话/授权期限与邀请30秒上限的最早值，不因accept、重投或新token关联而延长。

完整时序

已完成AI转人工后的人工挂断

上方完整时序图末尾的M75–82为此分支；逐条JSON和应答关联见下方索引，不另定义一份字段契约。

首次通知／释放总截止为min(首次时点+10秒, 原请求总预算, Owner/两腿/两连接租约, 人工业务截止)，投递和首次ACK共用，不因重试重置。平台Peer及忙线只在原提交已确认后停止；SQL未知的后继确认仍核原写集。原已完成End操作固定保留600秒，只允许原主体／会话／token／不可变请求精确读回，以及原已完成释放ACK字节的只读确认；不是允许首次迟到释放的新窗口。未确认资源保持unknown，无权恢复旧AI或另一腿。

本事件的failed是原requestToken关联的转接操作终态，不是原呼叫组或任一原会话腿的终态；不得随后结束D/D2，原实际媒体与忙线保持。候选拒绝、30秒未接听、首次45秒总窗到期、媒体失败、权限撤销或修订变化均只撤该候选代次；已分配时可携带原candidateSessionId，未分配不能编造ID。及时接听仅切换至原总窗剩余预算，原邀请字节及两项截止不因重投续期；旧邀请计时回调不得撤已接听候选。

发起者撤销候选（不改变原M01至M47编号）

在M16之后、候选实际媒体就绪原子切换之前，D可沿本端s13-session发送以下取消；平台必须核原主体/原转接账本/candidate代次及expectedRevision。此分支只结束候选D3，原D↔D2实际媒体继续；不执行M17/M18，不向原腿发送sessionEnded。不带candidateSessionId的已接通cancel仍按409 invalidState拒绝。

独立callState事件采用同一active/revision/candidateSessionId/reason并带requestToken=s13-candidate-cancel，事件自身使用新msgToken/eventSeq。candidateCancelled是操作结果，不是整体CallPhase。

异常、状态与资源释放

路由与信封见公共约定；阶段性状态不代表最终完成。操作终态时限见命令手册；编号、超时等元信息不发送。

能力不足422、无权限403、资源/修订号冲突409、超时504按S11处理，不静默开启设备能力。同token只重放原结果；事件按eventSeq去重，旧会话/端代次不可恢复。验证本页正常路径、alt分支及支持范围断言。文档通过不代表代码或硬件已实现。

D2为原被叫，D3为另一个已授权转接或人工端，彼此鉴权Topic和会话腿不得复用。原呼叫主叫同时申请麦克风sendonly和扬声器recvonly，不以只有上行的轨宣称双向通话。候选失败时撤销其邀请/Peer/令牌，原呼叫与资源占用继续；转人工分支是另一独立AI会话的示例。

AI转人工的失败与切换边界（扩展契约，须确认支持）

下表描述尚未实际suspend的失败。进入第三屏障后发生同类撤权、超时或取消，须按后面的分阶段补偿核对真实资源与路由提交结果，不能直接套用“原AI实际继续”。

触发原AI作用域结果新人际两腿清理原AI及共享驱动
D3或D拒接；忙线为sessionReject.reason=resourceBusyM58 reason=transferRejectedM59/M60 reason=userRejected原仍授权AI继续，不把拒接当AI终态
首次候选45秒或更早邀请截止到期M58 reason=transferTimeoutM59/M60 reason=inviteTimeout不续期；旧超时不作用于新候选
任一Peer协商/连通失败M58 reason=transferMediaFailedM59/M60 reason=mediaFailed不切麦克风/播放，释放候选Peer
目标明确撤权M58 reason=transferPermissionRevokedM59/M60 reason=permissionRevoked不向目标共享正文；原AI仍授权才继续
原主体权限读取未知或目标不可用M58 reason=transferUnavailableM59/M60 reason=mediaFailed未知不猜撤权或完成，不安装候选
D在提交前撤原候选M61/M62 state=active、reason=candidateCancelledM59/M60 reason=callerCancelled不发原AI sessionEnded；原token只重放
原AI用户结束或自身明确撤权原AI沿原sessionEnd/终态路径结束其尚未提交候选不用“失败保AI”绕过原权限或用户终止

M56–64示例分别展示拒接与取消的互斥路径；M59/M60的示例reason=userRejected只对应尚未suspend的拒接，其他提交前失败按表替换，并按各腿实际eventSeq推进。M58的failed是本次escalate操作失败，不把s-ai改成失败终态；但原AI会话保留不等于实际采集/播放已恢复。尚未分配双腿的422不带localSessionId/callGroupId，沿原token返回不支持原因，不凭service字面量选择管理员。

本次实现收敛：撤候选的双腿结束复用人际通话已有callerCancelled，不使用表中原设计的userHangup，因为撤销尚未提交候选不是挂断原AI。拒接ACK的result.state=ended并保留原请求的userRejected/resourceBusy/privacyEnabled；异步候选终态规范为userRejected。这些限定仅针对本次新人际voice候选，不能据此改变现行视频或其他用途的应答格式。

第三屏障与分阶段补偿（扩展契约，须确认支持）

阶段及证据平台与设备处理不能声称的结果
尚未实际suspend；M72仅在原驱动保证未执行时回denied清候选，原仍授权AI及实际归属保持；M65回执缺失不属于明确未执行不把未知suspend当保持原物理归属
M66已确认suspended；M69明确未acquire且路由明确未提交复核原AI权限、用户意图、原租约/完整组、截止和当前CAS，再发M70；只在M71实际restored后显示AI输入/播放恢复不凭原模型仍在线、候选已关闭或restore受理宣称active
acquire或路由提交未知，包括原回执/提交回复丢失保留原token、字节、代次与绝对截止，进行有界原操作查询或重放；设备保留实际单一归属/围栏，过期按原许可停止，不能续期或新建恢复意图不盲目restore导致双采集，不发transferred；不因没收到ACK推断未执行
M68原整组实际acquired且当前授权/候选代次/原连接/期限/CAS仍有效平台持久确认原回执与人际路由提交；之后M45/M55，再M46/M47M68本身不等于提交；Broker接纳、单轨active和mediaState.connected均非第三屏障
路由已提交后，本地驱动/人际媒体又失败按已提交新人际通话失败与资源归属收尾；迟到候选取消不能倒退提交阶段不回滚已经变化的路由、不以旧AI恢复伪装本次未切换、不冒报仍正常通话

M65–72不添加新method或焦点operation。M65/M66固定原AIs-ai/ai-conversation-focus，M67/M68固定原本端新人际腿s13-human-local/human-local-focus；关联来自原escalate账本，不按全局当前会话推测。每次操作只在完整实际组完成后推进设备全局revision；M69/M72拒绝不推进，原token重放原结果不再次切换。示例M70的expiresAt须是原AI仍有效许可、原租约与该次授权截止的最早值；M67须服从原候选/会话/授权截止，不因共享同一示例数字续期。若存在其他合法资源变化，先核实际新CAS，不能照抄11。

此处在途截止和已接通业务截止必须分离。内部HumanBusinessDeadline从原AI已配置且已授权的会话业务Deadline固定（双方IM授权若有更早截止取最早），并写入新人际双腿业务Deadline；45秒候选与30秒邀请只限制准备，双Peer实际就绪后首次固定的FocusDeadline最多15秒且不得越过原45秒或业务截止。M67的租约expiresAt取原持久人工业务截止，不取邀请期限；其请求/实际ACK和三屏障提交仍须在原焦点操作预算内完成。提交仅改变阶段，不刷新任何截止。旧意图缺这些来源保持未知/拒绝最终切换，不从ended、请求期限或Redis忙线续租补授权。当前期限分离已接入准备事务，最终人际组路由及持续Owner生命周期尚待接线和真实端云验收；完成后原AI模型/UDP结束只释放旧AI上下文，不能调用通用Owner关闭撤掉人工组，人工自身断连、撤权、租约失效或业务截止才按实际资源终态收尾。

仅对原授权escalate账本绑定的prepared候选，在建立前严格特批M67及其M68/M69回执；目标腿、原AI、呼叫组、原连接、能力、候选/媒体代次和期限都须固定验证，普通negotiating会话仍不得操作焦点。后端已实现原内部出处的有限特批、原Queue/完整ACK及生成RPC边界回归；实际共享宿主与最终平台提交尚未闭环，不能用组件回归倒推端云已支持。

人工取得屏障包含两端，不仅本端D。双Peer prepared之后，平台先向D3的原remote腿按M67合同发送独立完整组focusControl.acquire；D3按M68合同回原token实际acquired后，才对D发M65/M66，随后D的M67/M68。D3必须是明确pureHuman接收端并具有自己的首次完整idle出处；D3已有AI租约、资源未知或在途控制均拒绝，不能隐式取消目标AI。两端各有独立连接/Owner栅栏、focusId、资源CAS及实际ACK，expiresAt均取原持久HumanBusinessDeadline，不越过原阶段期限取得。最终三CAS需核两个当前完整组实际租约；prepared、CheckVoice、Broker接纳和一端ACK都不足以切换。本段没有新增报文method、escalate ACK字段或设备自报权限，双端真实移交仍待验。

共享采集对象在候选等待期始终由原AI持有。M66之后旧AI转发停止，M68只在同一物理对象已实际归属新人际采集/播放后成立；候选媒体仍由平台屏障禁转，直至原持久提交明确成功。M43/M53只证明网络连通；M45/M55是完成第三屏障与路由提交后的确认，不再触发尚未证实的移交。D须把它们同原关联及已完成焦点事实核对，才能呈现M46或释放M47的旧AI资源；跨会话事件不可按最新session猜测。旧AI释放不得顺带关新人际驱动，晚到旧AI音频/文本/工具结果必须围栏。全过程扩展契约，须确认支持，不以一次mediaState或“transferred”文本认定切换。

后端旧AI完整组正式释放已接原Owner持续入口：四条最终通知的原ID/SHA都已交Broker后才排唯一focusControl.release，实际设备仍需核原AI终态及原资源；不把Broker接纳称设备完成。原生成入口的完整成功ACK写独立原释放墓碑，连接全局CAS前进而新人际租约与Peer不变。后继Human保持/恢复仍以原callControl token跨两腿各自focusControl关联，不能混用呼叫修订与资源修订；双完整组实际ACK之后才发held/active。原十秒释放截止、SQL未知读回和原实例替换均有受控回归，私有上下文原合法读取/留存ACK不因精确旧AI释放失效；这不是实际两共享宿主/模型/Broker端云通过记录。

合法保持/恢复须先确认原旧AI正式释放完成；四通知仍pending、释放排队或未知都不能先停人工RTP或占用双方焦点。原typed409拒绝不改媒体，业务期限及Owner到期仍精确关闭人工组，不以等待释放延长授权。

第一实现阶段可保持不分享上下文，但授权分享仍是后继必须实现项：需要真实Consent引用校验、撤销及限定范围交付。拒接、忙线、撤销、超时不需要分享同意，不能为候选清理要求额外consent。

后继实施验收断点

  • 正式AI Owner受理escalate，原token幂等、修订冲突、授权目标与两腿关联；当前拒绝入口不能假装支持。
  • 两个邀请乱序抵达、错组/错腿/错原token、关联超时有界丢弃；普通来电不自动抢占AI。
  • 仅D3 accept或仅一腿网络就绪时，原AI实际输入/回复持续；同时验证只有一条物理采集路径。
  • 无原完整租约、仅speaker能力、缺实际microphone驱动、普通negotiating腿及错候选关联均拒绝；不凭priority提权或开启第二套采集。
  • M65–72完整资源/token/CAS关联、单资源假成功/迟到代次拒绝；实际suspend后明确未acquire才允许受授权restore，实际restored前不报active。
  • 原回执丢失、路由提交回复丢失、恢复拒绝及授权/期限变化均保守未知；不盲恢复、双采集或续期，不回滚已提交路由。
  • 两腿真实双向非静音解码、整组实际acquired后的再次授权/代次复核与持久提交，以及旧AI关闭不影响人工媒体。
  • 拒接、忙线、45秒到期、撤候选、目标撤权、未知读失败保留仍授权AI；原AI结束并发候选就绪不得复活。
  • 成功/失败终态后迟到的旧AI内容、旧候选事件与旧定时器不能污染新腿；原token重放不重复邀请/切换/续期。

上述为待实现测试用例，不是新增真实通过记录；人际第16轮保持/恢复事实及原历史产物不因本次文档hash变化重写。
