 ## Stage flow
 
-Before the first file mutation, code execution or paid asset operation, call `agc_register_delivery_contract` with the required `scope`, `changeKind` and a nonempty `requirements` array. Each requirement has a unique `id` and one kind: `artifact` with `path`, `command` with `program/arguments/cwd/purpose`, `visual`, or `gameplay` with its fixed `scenario`. Reading and ordinary chat need no contract. Register the scope once and do not expand it later. New Web projects must include the required build, visual, and gameplay checks. Do not self-report pass flags or hand-written evidence; completion requires actual changes or current trusted validation. Use `agc_delivery_status` when a required check is missing.
+When the user asks you to make, complete, or deliver a game, call `agc_register_delivery_contract` with `scope`, `changeKind` and nonempty visual/gameplay `requirements`. Interpret the actual user request. File edits, commands, image generation and validation do not require registration. Freeze the requested delivery scope once; never submit pass flags or fabricate evidence. New Web contracts retain the existing dual-viewport visual and gameplay minimums, returned in the registration result. `agc_delivery_status` only reports progress; automatic review happens after your response completes, so finish the user’s requested work and reply normally.
 
 Use `agc_apply_patch` for targeted source edits with the official Add/Delete/Update/Move syntax in the current project. Track progress with `agc_update_plan`; completed plan steps never replace delivery evidence. Independent patch, plan, read and resource calls can run concurrently. Wait for required inputs, earlier edits of the same file, and completed builds before starting dependent work. If user information is missing, ask through the normal conversation.

 2. **Project and asset inventory** — Inspect the existing project structure and call `agc_list_registered_assets` (and `agc_list_project_files` when needed). Record which requested visuals already have usable registered identities and which are missing. Do not invent asset identities from filenames.
 3. **Visual production** — For missing or unsuitable visuals, call the reviewed `agc_tools` workflow: use `taonier_prepare_game_art` for a complete package, or `agc_generate_image` / `agc_edit_image` for focused assets. Read returned paths, identities, and warnings. A warning or partial package requires a narrower retry or independent assets before continuing.
 4. **Game implementation** — Implement the complete playable loop and wire the returned project-relative asset paths into the actual runtime. Every required character, object, background, effect, and UI visual must have a real source or an explicit brief-level decision to remain code-native. Generated assets that are unused, documentation-only, or replaced by emoji/CSS placeholders do not satisfy this stage.
-5. **Build and local verification** — After the needed implementation, record the build through `agc_run_validation` with `purpose=build`, `program=npm`, `arguments=["run","build"]` and the package `cwd` (`game` for a new Web project). Confirm the actual playable entry under `dist` and fix build or asset-loading failures before preview. Use `purpose=test` for a declared focused test. A successful raw shell command does not replace the recorded `agc_run_validation` build result.
+5. **Build and local verification** — Build and test as needed using the available command tools or `agc_run_validation`. Inspect actual command results and fix build or asset-loading failures before preview. Build/test return values and file existence are not contract requirements; visual/gameplay checks still require their existing trusted browser evidence.
 6. **Validation** — Use the approved browser tool and fixed scenarios. Call `agc_browser_playtest` with `mode=visual` for art/layout checks or `mode=gameplay` for fixed real-input/state/restart checks. Use `agc_run_validation` for existing focused Node/npm tests when needed. Fix blocking findings and rerun only the affected layer after an actual change. Do not rerun a whole playthrough for a color or documentation edit. A visual pass does not establish gameplay or complete-level coverage.
 7. **Delivery** — Once required evidence matches the current input, stop and report the observed validation scope. Do not start another side effect, art cycle, or polish cycle. A fixed scenario is not a full long-level playthrough. List new nonblocking ideas as follow-up work. Missing required evidence remains an explicit gap.

 Use `agc_apply_patch` for official patch operations and `agc_update_plan` for progress updates. Use the names in the actual tool catalogue. Patches are bounded to the current project; successful plan steps are progress only. Independent calls may overlap a slow asset operation, while edits to the same file, asset integration that needs returned identities, builds, and checks retain their dependencies. Required in-flight work must settle before delivery. A nonzero patch result can retain partial changes; inspect current state before proposing a repair. Timeout, cancellation and uncertain execution require reconciliation, not automatic replay.
 
-`agc_register_delivery_contract` must be called before any mutation, execution or paid generation. Supply requirements, never pass flags. Artifact requirements use project-relative paths; command requirements bind program, arguments, cwd and build/test purpose; visual and gameplay requirements use actual dual-viewport evidence. New Web games must include the required build, visual, and gameplay minimums. Unchanged pre-existing artifacts need current trusted validation; replaying a contract does not make them newly validated. Required in-flight work must settle before delivery. Trusted validation evidence is authoritative, not a project-side report or the model's final message.
+When the user requests making, completing or delivering a game, register the requested visual/gameplay requirements with `agc_register_delivery_contract`. Interpret intent from the user’s request. No contract is needed to permit ordinary file writes, commands, generation or validation. Artifact and command-return requirements are not supported. New Web contracts retain the existing visual/gameplay minimums shown in the registration result. Trusted browser evidence remains authoritative. Status queries and operation completion do not seal the turn; automatic delivery review follows a normally completed response, with required work settled before final delivery.
 
 Validation is layered: visual checks do not prove gameplay, and a bounded fixed scenario does not prove an unobserved full level. Browser and hosted external checks must not be evaded by switching tools. Reuse successful evidence for unchanged inputs; a blocking defect justifies only its affected validation layer. Once all required evidence exists, deliver. Optional polish is follow-up work, not another mandatory production cycle.

 ## Workflow
 
-Before the first mutation or command, register the bounded required scope with `agc_register_delivery_contract`; ordinary read-only diagnosis needs no contract. Declare actual artifact, command, visual or fixed gameplay requirements. Use `agc_run_validation` with `purpose=build` for the declared `npm run build`, then the affected validation layer. When the turn is completed, exhausted, or interrupted, stop; do not expand scope or continue through another tool.
+When the user asks you to make, complete or deliver a game, register the bounded visual/gameplay requirements with `agc_register_delivery_contract`. Interpret the user’s request. Ordinary file writes, commands, image generation and validation can proceed without registration. Build and test as needed using the available tools, then run the relevant browser checks; artifact and command-return requirements are not supported. Status checks do not stop execution; automatic contract review follows normal response completion. When the turn is completed, exhausted or interrupted, stop new operations.
 
 Make targeted source changes with `agc_apply_patch` using the official patch syntax. Use `agc_update_plan` for a multi-step task's progress. Independent edits, reads, plan updates and resource calls may run in parallel; wait for earlier edits to the same file and for dependencies needed by builds or validation. A failed patch may have partially changed the project, so read the current files before constructing a new patch. Stop on timeout, cancellation or `needsReconciliation=true`. For a complete text-file replacement, `agc_write_file` accepts the original UTF-8 body.

+- 验证失败和源码漂移影响对应证据，不阻断无关工作。远端不确定结果沿资源自身 operation/幂等记录核对；本地执行器失控或持久状态损坏仍结束回合。
+- 保留累计执行时间、整轮墙钟、原生执行前审批、关闭时清理与原回合写入/付费提交检查。模型执行结束时先关闭准入，确认清理后才允许交付反馈继续；普通失败不进入关闭阶段。
+- `validation.maxRuns` 只保留交付回复复核用途；合同的创建与两类要求简化见下条决策，视觉/玩法判据保持原样。图片工具仍等待结果，Codex 调度不变。
+- v2 执行账本只对白名单 v1 字段迁移，保留预算与终态，不恢复旧活动权限；没有可信时间记录的更早项目侧账本不授予同回合新预算。
+- 权威边界与验收入口：[AI 游戏创作智能体 App 实施计划](../../technical/【技术方案】AI游戏创作智能体App实施计划-2026-06-24.md#direct-操作控制2026-10-04)。Windows Job 退出证明仍须由 Windows 环境验收。
+
+## 2026-10-04：Direct 合同按用户意图登记、正常响应结束后复核
+
+- 合同自动检查只在模型正常结束响应后触发；删除操作结算与补丁成功触发的提前封口，状态查询保持只读评估。异常终止与预算耗尽仍独立处理，不以证据齐备覆盖失败事实。
+- 提示 Agent 在用户要求制作、完成或交付游戏时登记合同，由 Agent 理解用户意图；首次输入也按同一用户意图条件登记，提示与技能不另设空项目或首次输入的免登记说明。无合同既不阻断普通操作，也不阻断正常结束。
+- 删除 artifact/command 合同要求及宿主自动补入项，保留普通文件、命令与构建能力。视觉/玩法的现有判据和证据真实性校验不改，仅在主动注册后应用原有新 Web 视觉/玩法补充；用户于 2026-10-05 确认这两类检查保持现状。
+- 旧未完成合同不得因过滤退役要求变成成功；保留旧预算、终态和操作身份，版本迁移与恢复有独立验收。
+- 权威规则：[Direct 合同规则](../../technical/【技术方案】AI游戏创作智能体App实施计划-2026-06-24.md#宿主验收与执行许可合同)。运行时已实现；验证边界保留在主规范，不以协议夹具代替真实模型或 Windows 专项证据。

 - 不修改 Provider 的 maxRetries；不减少引擎或任意代码执行的合法能力，不引入平行 Agent 框架，不改公开 API/数据库，不提交私密运行记录。
 
+### Direct 操作控制（2026-10-04）
+
+本节与下节共同描述当前 Direct 操作控制，执行/返修批次与全局 Draining 已移除。操作控制不改变 Codex 的工具调度、模型循环或图片工具的等待返回方式。
+
+- 普通操作开始前，宿主检查原回合是否活动、时间预算是否足够、并发容量是否可用，并执行原有权限、路径及资源约束。交付合同是否存在、前一个工具是否成功不构成普通操作的准入条件。
+- 操作成功、失败或取消后结算占用与用时，返回真实结果，由 Agent 决定后续操作。没有全局 Draining、执行/返修批次计数及对应重试门禁；验证输入变化只使相关证据失效，不使无关工作停顿。不新增租约到期续租、Agent 释放租约或独立后台任务接口。
+- 保留原时间预算数值与累计口径、并发上限及回合身份。回合关闭、取消或时间耗尽后拒绝新操作，取消自有在途工作并核实本地进程退出；等待资源锁后的写入及每次新增付费提交仍核验原回合权限。操作记录清除不能代替执行结束证明。
+- 普通工具失败和资源级结果不确定不终止整个回合；资源自身的幂等、operation ID、恢复及对账继续有效，不能因客户端取消而推断远端取消，也不能盲目重复付费。宿主控制状态损坏或无法确认自有执行器退出仍按实际控制失败处理。
+- 交付复核与操作准入分离。合同由 Agent 按用户制作/交付游戏的意图登记，验收仅在正常响应结束后启动，当前只保留视觉/玩法要求。`validation.maxRuns` 暂保留现有交付复核次数用途，不再用于执行/返修批次；时间配置不变。
+- 同回合重试或进程重启不刷新预算；仅保留预算、回合归属、必要退出记录和资源自身恢复所需的持久状态，不恢复旧租约为可执行权限。旧版本未结束状态须先确认旧执行器退出，不能通过直接删除账本解除控制。
+
+验收至少覆盖失败图片与长命令并存时无关写入成功、连续工具失败不触发返修次数限制、所有退出路径释放并发占用、关闭后零新增执行/付费提交、迟到写入被拒绝，以及远端不确定任务不重复提交。Linux 进程组清理不冒充 Windows Job 的完整子树退出证明。

+验证边界：Linux 定向回归已覆盖操作准入、合同复核与恢复、实际子进程退出、无合同及 ready 合同完整回复、进程扫描不确定性、迟到关闭通知与收尾预算报告。用户已确认手动 GUI 检查完成。未提供 Windows Job 完整子树退出及 Windows 捆绑补丁专项结果，也未以真实模型多语言意图或付费 Provider 场景替代协议夹具；这些边界不因合入或清理临时计划而视为已验证。后续目标平台验证沿用现有测试与本规范。

 ### 宿主验收与执行许可合同
 
 - 正式 GUI 和 CLI 的共同 Direct 回合入口建立宿主控制状态，绑定 canonical 项目路径、稳定 clientTurnId 和原始用户输入摘要；宿主私有目录保存权威账本并独占该回合，项目 `.agent` 仅允许保存展示副本。配置或项目侧文件被改写、工具切换、Provider 重试和进程重启不得刷新同一回合的预算。
 - Direct 回合集成测试也按生产入口计算原始用户输入的 SHA-256 十六进制摘要（64 字符），不能用请求名称替代。用户回显过滤回归继续覆盖实时消息去重、回合起止身份关联及历史落盘过滤。
-- 直接启动 Direct 工具桥的图片生成通知测试，须复用真实宿主执行会话与已登记交付合同夹具，再发起工具请求；继续验证资源提交后发出 manifest 失效通知，以及空提示词被参数校验拒绝且不发通知，不绕过执行许可门禁。
-- 普通聊天与读取不要求交付合同。首次修改、代码执行或付费扩项之前，模型通过结构化工具登记本轮必需范围与验收项；合同非空、有界且只冻结一次。模型只能声明要求，不能提交“通过”作为证据。后续扩项留到新的用户回合。
-- 明确新 Web 创建由宿主可信脚手架凭证及尚未交付的宿主记录判定，CLI 同样据此判定，不从提示文本猜测；这种回合即使模型没有调用工具或没有登记合同，也不得按普通聊天宣布交付。已有项目只有未激活合同且从未产生副作用时才允许直接聊天结束。
-- 验收项为明确类型的产物、构建/测试命令、双端视觉或指定固定场景的双端玩法。可信新 Web 游戏由宿主补充构建、双端视觉和玩法底线，不能由模型声明“已有项目”降低。已有项目按冻结的变更范围选择层级；平台美术只在用户目标要求时成为必需项。
-- 同一份双端玩法证据可同时满足视觉项，避免重复浏览器运行。构建证据分别绑定源码输入摘要与输出摘要，正常生成 dist 不算源码漂移；浏览器证据绑定构建后的实际运行输入。只有宿主验证完成产生的结构化结果和证据文件摘要能满足合同，项目内自行写出的验证 JSON 无效。
-- 产物项的初始摘要由宿主冻结，模型不能提供或在重放时重算。仅登记已经存在的文件不能立即交付：产物必须实际变化/新出现，或有当前指纹的宿主可信验证证据；原生修改和工具修改遵守相同判据。
-- `validation.maxRuns` 保留已配置值，语义为执行/返修批次上限；首次执行开启第一批。开发期正常成功命令和源码编辑共享本批，不逐条消耗次数。开始验证后绑定输入，执行失败或验证期间输入漂移使本批进入排空状态，关闭新的执行入口，等已受理操作结束后才开启下一返修批次。读取与结构化编辑不单独消耗次数。
-- `validation.maxExecutionSeconds` 默认 900，必须为正整数，是整个 clientTurnId 的累计执行时间上限，换批次不清零。并行操作分别计时累加，内置工具不与 app-server 的外层 MCP 事件重复计费。时间耗尽立即拒绝新执行、写入和付费扩项，保留最近证据与未完成项；Provider 的重试次数保持独立。
+- 直接启动 Direct 工具桥的图片生成通知测试，须复用真实宿主执行会话夹具，再发起工具请求；继续验证资源提交后发出 manifest 失效通知，以及空提示词被参数校验拒绝且不发通知，不绕过执行许可门禁。
+- 交付合同不参与普通工具准入。模型通过结构化工具登记本轮游戏交付的必需范围与验收项；合同非空、有界且只冻结一次。模型只能声明要求，不能提交“通过”作为证据。后续扩项留到新的用户回合。
+- 当用户要求制作、完成或交付游戏时，由 Agent 理解意图并登记合同。首次输入也按同一用户意图条件登记；宿主不做关键词或 LLM 意图分类。无合同回合可以正常写入、执行、生成和验证，也可在必要清理后结束，不触发缺合同返修或生成游戏交付证明。系统提示、工具描述及随包技能遵循同一条件。
+- 新合同格式为 `agc-direct-delivery.v2`，只接受非空、有界的 visual/gameplay 要求。artifact/command 类型、初始文件变化摘要及 host-entry/host-build 已删除；普通文件、命令、构建和 agc_run_validation 工具及真实失败回执保留。主动登记新 Web 合同时，宿主沿用首次交付事实补充既有双端视觉/玩法底线并返回完整要求；未登记不补合同。冻结后同参重放复用 newWebGame，不重算范围。用户于 2026-10-05 确认视觉/玩法检查保持现状，本次重构不继续调整这两类判据。
+- 同一份双端玩法证据可同时满足视觉项，避免重复浏览器运行。视觉/玩法仍校验双端、固定场景及版本、当前运行指纹、报告与截图摘要；只有宿主真实验证回执有效，项目内自行写出的验证 JSON 无效。删除 artifact 要求不删除浏览器证据文件的防篡改校验。
+- `validation.maxRuns` 保留已配置值，仅用于交付回复复核次数；普通执行成功、失败、取消和验证输入漂移均不消耗该次数。验证证据继续绑定输入，失败或漂移仅使相应证据不能证明交付；Agent 可以继续无关工作。
+- `validation.maxExecutionSeconds` 默认 900，必须为正整数，是整个 clientTurnId 的累计执行时间上限，同回合重试不清零。并行操作分别计时累加，内置工具不与 app-server 的外层 MCP 事件重复计费。时间耗尽立即拒绝新执行、写入和付费扩项，保留最近证据与未完成项；Provider 的重试次数保持独立。
 - `validation.maxTurnSeconds` 默认 1800，必须为正整数，是同一宿主回合从开始起的墙钟上限，重启不重置，用于约束模型空转和超出单个工具事件边界的后台会话。墙钟上限与累计执行时间分别记录，任一耗尽都收束自有执行器；不能把模型等待时间报告成工具执行时间。
 - 捆绑 app-server 的原生命令使用已验证的逐次审批能力；宿主只返回单次接受/拒绝，不允许会话授权或 exec policy 修订。第三方 MCP 必须显式启用逐调用询问，不能依赖不可信 readOnlyHint。询问缺少调用 ID 时，按服务器与回合中的并发组保守管理，不能解析展示文案猜测归属。
-- 原生、内置与第三方所有入口都经过同一宿主状态；独立工具继续并行，只有身份、批次切换、收尾与必要资源冲突形成短临界区。能力检测失败不得退回无控制执行。
+- 原生、内置与第三方所有入口都经过同一宿主状态；独立工具继续并行，只有身份、回合关闭、收尾与必要资源冲突形成短临界区。能力检测失败不得退回无控制执行。
 - 上述回合控制适用于 DirectProject。独立客户端 HTTP MCP 显式使用 ExternalClient 来源，保持其原有权限、幂等和浏览器能力，不借用当前项目另一条 Direct 回合的预算或可信证据；新交付合同与托管验证命令工具要求 Direct 会话。服务端 external_mcp 不变。
-- 必需证据齐备后，宿主先进入封口状态，拒绝新副作用，再确认在途归零、收束模型执行器并取得进程退出证明，最后重新核对源码、产物和证据摘要；核验成功原子进入 completed 并产出宿主报告。不能先写 completed 再尝试停止后台进程。宿主主动结束模型回合属于交付终态，不触发普通错误反馈或重试。未达标不得用模型最终回复替代验收。
-- Windows app-server 在任何模型工具执行前绑定不可脱离的自有 Job，超时/取消/断连时验证整个 Job 已退出。其它平台继续保留受控进程组；未取得完整子树退出证据时按不确定状态报告，不宣称全部后台执行已停止。已受理的远端付费任务保留原不确定围栏，断连不构成自动重放授权。
-- 付费许可始终绑定原回合和原租约，不能在容量或同动作锁排队结束后借用新回合。排队可取消，每次新 POST 前与封口共用宿主状态短锁，核对原许可、期限与阶段并持久化提交边界；封口、终止或耗尽后不得新增提交。已经越过提交边界的请求不丢弃，其 operation ID 和不确定状态继续持久化并允许原 GET 对账，多阶段生成的下一次 POST 仍须重新核验。ExternalClient 与手工资源操作保持既有语义。
+- 自动交付验收只在模型正常结束本次响应后启动；操作结算、AGC 补丁成功、登记与状态查询都不触发封口。正常完成后证据齐备则进入 Sealing，拒绝新副作用，确认在途归零和执行器退出，再复核运行输入及证据，成功才进入 Completed 并返回宿主报告。未达标仍在原预算与复核次数内反馈修复；取消、耗尽、断连等异常终止保持其原因，不能因证据齐备改成成功。
+- Windows app-server 在任何模型工具执行前绑定不可脱离的自有 Job，超时/取消/断连时验证整个 Job 已退出。其它平台继续保留受控进程组；受控归属退出可用于回合收尾及合同完成，但进程组证明不宣称逃逸后代或完整子树均已退出。正常操作回合在 Closing 清理后返回 Working，再由回复复核完成；已封口回合保持 Sealing 直至验收完成。缺失或失败的归属清理仍进入 Interrupted。已受理的远端付费任务保留原不确定围栏，断连不构成自动重放授权。
+- Linux 进程组检查排除僵尸；目录枚举失败或数字 PID 的状态不可读取、不可解析时，不以不完整扫描证明组为空，回退到进程组存在性检查。已确认消失的 PID 可以忽略；非进程目录不参与扫描。
+- 无合同收尾在预算检查中产生终态报告时，回复复核优先返回已持久化报告；没有终态报告的关闭失败仍保留真实错误，不把预算耗尽改成 Completed。
+- 宿主正常关闭连接产生的迟到通知仅作为诊断，不为 Working/Closing/Sealing 生成终态报告，也不改写 Completed 的回复；只有 Interrupted/Exhausted 的既有失败终态可以追加收尾说明。
+- 付费许可始终绑定原回合和原操作，不能在容量或同动作锁排队结束后借用新回合。排队可取消，每次新 POST 前与封口共用宿主状态短锁，核对原许可、期限与阶段并持久化提交边界；封口、终止或耗尽后不得新增提交。已经越过提交边界的请求不丢弃，其 operation ID 和不确定状态继续持久化并允许原 GET 对账，多阶段生成的下一次 POST 仍须重新核验。ExternalClient 与手工资源操作保持既有语义。
+- 执行账本使用 `agc-direct-execution.v3`，删除 requiresContract，保留回合预算、归属、活动操作、退出证明及合同证据。读取 v1/v2 只白名单移除退役字段，未知字段仍拒绝；旧终态不重开，含旧合同的非终态保留要求并转为 Interrupted，提示新用户回合继续，不因删除要求宣告成功。旧无合同账本移除强制标记后仍按原预算与活动操作恢复规则处理；更早项目侧验证账本缺少可信时间，不能授予同回合新预算。旧合同终态可查询历史但不再按新标准评估。
+- 模型一次执行结束时先进入 Closing，关闭新操作和迟到提交，核实自有执行器退出及活动操作归零后才能回到 Working 接受交付反馈；整个用户回合结束后撤销旧许可。Closing 只用于实际关闭，不由普通工具失败触发。普通无合同回合完成不宣称游戏验收通过。
 - 本地写事务未结算或失败仍需核对时不得封口。与失败写入重叠的旧写入/旧验证不能清除该围栏；只有失败之后新准入的成功修复或可信验证可以恢复验收。普通文件写入与账户/本地资产导入显式携带原写入许可，取得项目锁后再与宿主状态锁共同核验期限并提交短本地事务；等待锁或下载期间终止的请求不得继续落盘，网络等待不持宿主状态锁。
