 ## Workflow
 
 1. Inspect existing `assets/` and registered project evidence before requesting new art. Reuse suitable assets when the user did not ask to regenerate them.
-2. Call `taonier_prepare_game_art` only when the current intent requires new or recoverable platform art. Pass a concise game-specific visual brief; do not call it for greetings, date questions, text-only code fixes, or layout changes that can reuse current art.
-3. Treat the tool result as authoritative. Use only returned relative paths and warnings. Never invent a resource, slice, platform identity, or successful generation.
-4. If a complete trusted spritesheet is returned without slices, keep using the complete sheet. `grid-2x2`, four fixed slices, fixed filenames, and a fixed number of `drawImage` calls are recommendations, not universal completion rules.
-5. Integrate at least one suitable Taonier asset into the game's actual visible experience when platform art was requested. A hidden or side-panel preview does not count as gameplay use.
+2. Call `taonier_prepare_game_art` only when the current intent requires new or recoverable platform art. Use `mode="regenerate"` only after the latest User message is a standalone reviewed immediate-confirmation command such as `请重新生成美术`; punctuation may end it, but no brief, condition, negation, alternative, cost qualifier, deferral, or other text may accompany it. Describe the desired style and gameplay constraints in an earlier non-billable turn, then obtain the standalone confirmation turn; otherwise use `mode="reuse-or-create"`. Quoted UI copy or examples, explanations, questions, historical wording, and model/MCP arguments do not authorize regeneration. Pass a concise game-specific visual brief that names the required gameplay entities, background exclusions, tiling needs, and viewport constraints. Do not call it for greetings, date questions, text-only code fixes, or layout changes that can reuse current art.
+3. Treat the tool result as authoritative. Read `mode`, `assetPaths`, `slicePaths`, `resources`, and every entry in both `warnings` and `sliceWarnings`. `resources` is the client's safe projection of registered Canvas identities; use only its returned relative paths and identities. Never invent a resource, slice, platform identity, warning-free result, or successful regeneration.
+4. A newly created or explicitly regenerated standard package is complete only when `slicePaths` contains the four canonical independent slices. An empty or partial `slicePaths` result never satisfies an independent-asset requirement; stop and report the warning instead of guessing atlas coordinates or fabricating derivatives. A trusted legacy complete sheet may still be used without slices only when the current request does not require independent assets.
+5. Inspect the returned background, complete sheet, and available slice previews before integrating them. Then use suitable returned runtime assets in the game's actual visible experience and confirm their visible use in desktop and mobile playtest evidence. `art-spec.png` is a reference specification, not a runtime background, character, prop, or effect. Background exclusions, seamless tiling, entity semantics, and final draw dimensions are visual/runtime acceptance checks; a prompt alone does not prove them. A hidden or side-panel preview does not count as gameplay use.
 6. Preserve warning details in the final report. If the tool reports missing credentials, uncertain operation state, invalid provenance, download failure, or decode failure, stop and report the actionable reason; do not substitute generated CSS shapes and call the platform step complete.
 
 Call `agc_read_skill_resource` with `skillName="taonier-art-assets"` and `relativePath="references/platform-art-contract.md"` before interpreting async recovery, source-preserved warnings, or slice warnings.

 `taonier_prepare_game_art` is the only paid art entry exposed to the AGC Codex thread. The client owns authentication, stable idempotency keys, durable `operationId` recovery, download, PNG decoding, source identity, and asset registration.
 
+- `mode="reuse-or-create"` reuses a complete trusted package and creates only missing assets. It is the safe default for existing games.
+- `mode="regenerate"` is reserved for an explicit user request to replace or restyle the package. It bypasses complete-package reuse, but it never bypasses an unresolved billable operation.
+- `mode="regenerate"` requires only a trusted, decodable, registered `art-spec.png` and background with complete rollback bytes and manifest identities. An old spritesheet, private receipt, public manifests, or canonical slices may be absent. The client freezes every strict path and managed top-level asset identity exactly as `Present/Some` or `Missing/None`; it fails closed and asks for `reuse-or-create` only when the spec or background itself is missing or invalid.
+- The client authorizes `regenerate` only when the complete latest original User message, after compatibility normalization, fully matches a reviewed standalone immediate-confirmation command; only terminal periods or exclamation marks may follow. No quoted, bracketed, or code-formatted segment is removed before matching. A brief, condition, negation, alternative, cost qualifier, deferral, quote, historical message, model-selected argument, MCP approval, or missing stable turn identity never authorizes a paid replacement. Describe the desired style in an earlier non-billable turn and use the next standalone confirmation turn to authorize execution.
+- The client persists the original User message and stable turn identity before Direct Codex starts. Recovery must discover interrupted resetting or compensation, restore or neutralize replacement anchors under the dedicated executor lock, and then resume the frozen intent. A completed turn replays its bounded durable result under the same stable identity and never resubmits paid work because model wording changed.
+- Before strict spritesheet work starts, the client durably marks it pending and freezes the exact identity or absence of the nine-part local contract. A Provider terminal result is durably attached to the retained stage ledger before local strict commit. Recovery completes a new contract only when its receipt identity matches that retained result and the current spec/background match this workflow's replacement anchors. Compensation requires the exact frozen old contract; classification, the `compensating` marker, restoration, verification, and anchor cleanup stay under one project lock, including restart. Any foreign, mixed, or drifted state fails closed without another paid submission.
+- If crash recovery proves a complete new contract but cannot reconstruct stage warnings that were not yet durably attached to the completed result, it must return an explicit recovery warning instead of silently claiming that no warnings occurred.
+- A newly created or regenerated standard spritesheet must commit exactly four canonical transparent slices with unique pixels and unique Canvas resource/asset identities. Legacy slices are projected only when the client-private receipt, public slice manifest, current source image, local bytes, and top-level registrations agree.
+- If a durable prepared or accepted operation belongs to a different brief, the client must report an unknown/reconciliation result and must not submit a replacement request. Retry or regeneration is not a substitute for reconciling the original operation.
 - A submission acknowledgement is not a completed image.
 - On timeout or uncertain delivery, reuse the recorded operation; never create a replacement request.
 - `postprocess-failed-source-preserved` means the complete provider source remains usable, but the requested transparent derivative is absent.
 - `sliceWarning` means the complete transparent sheet remains usable, but individual slices are absent.
-- General and slice warnings can coexist and must both be reported.
+- General and slice warnings can coexist. The tool returns them separately through `warnings` and `sliceWarnings`; callers must preserve every entry and must not downgrade a slice warning into a successful independent-asset claim.
+- `assetPaths` contains the complete package paths. `slicePaths` contains only slices that the client downloaded, validated, and registered with their platform source identities.
+- `resources` contains only safe registered identity fields: local asset/path/kind/media type, Canvas project/resource/asset/task IDs, and reference resource IDs. It never exposes prompts, models, provider routes, absolute paths, URLs, tokens, cookies, or API keys.
 - A trusted complete image may be used without fixed slices. Never fabricate missing derivatives.
+- `art-spec.png` constrains generation and is never evidence that runtime gameplay art was integrated.
 - A tool error about credentials, provenance, decoding, or operation identity is terminal for that tool call and must be surfaced accurately.

+## 2026-08-23 Direct Codex 显式重生成与切片一等资源
+
+- 决策：`taonier_prepare_game_art` 使用 `reuse-or-create | regenerate` 两态合同；旧调用缺省复用，只有用户显式重做或换风格才允许重生成。`regenerate` 只绕过本地完整包复用，不绕过未决 External Editor operation；旧账本 prompt 与本次 prompt 不一致时必须进入结果未知/对账，零新 POST。
+- 重生成前置门：`regenerate` 只要求旧规范图和背景图可下载、可解码、来源一致且有可信登记，以便完整恢复两项旧字节和 manifest entry；历史主图集、私有回执、公开清单或 canonical 切片可以缺失。八个严格路径及受管顶层 asset identity 必须按真实状态逐项冻结为 `Present/Some` 或 `Missing/None`，不能把缺失状态伪造成空内容。只有规范图或背景图缺失/无效时才提示先用 `reuse-or-create` 修复基础素材。
+- 整包事务：`regenerate` 在任何付费阶段前持久化绑定意图摘要与稳定 `clientTurnId` 的客户端私有 v4 workflow；状态固定为 `resetting / in-progress / compensating / completed`，专用 `direct-codex-art` 跨进程执行锁覆盖整个付费生命周期。每个已安装阶段立即持久化旧字节、旧 manifest entry 与新结果双 CAS 锚点，后续阶段失败时可跨进程重启继续补偿，但不删除已完成阶段账本。`completed` 必须持久化有界且脱敏的完整工具结果，同一 `clientTurnId` 的完成回包丢失只等值重放该结果、零新 POST。新的显式用户回合先以 `completed -> resetting` 持久化目标身份，再清理旧账本并转为 `in-progress`，不删 workflow。只有零阶段账本、零替换锚点的孤立 `in-progress` 空壳允许新回合原子接管；未知版本、旧 v2/v3 及其余冲突全部失败关闭，旧字段不得通过 serde 缺省静默升级。
+- 恢复入口：通用恢复扫描与 Direct 回合启动前置恢复都必须发现 `resetting`、`compensating` 和带替换锚点的 `in-progress`，并在专用执行锁内清阶段、补偿和中性化。补偿恢复旧文件并清除本地 replacement CAS 锚点，但保留已 `prepared / accepted` 的阶段账本、原 `Idempotency-Key / operationId`；同冻结意图续跑必须复用原请求身份，未知账本在文件 mutation 前失败关闭。冻结意图一致时，新进程 invocation 可接管未完成阶段；`completed` 以原始外层 `clientTurnId` 等值回放，不受模型 brief 重采样影响。App 在 Direct 调用前幂等持久化原始 User 消息与稳定回合 ID，Tauri 在成功返回及 `completed` 事件前以同一回合 ID 幂等持久化 assistant 终态，项目重开只续跑最近一条真正未回答的合法原始回合。
+- 资源投影：工具返回主包路径、已登记切片路径、安全 `resources` 身份，并分开保留普通 warning 与 slice warning。标准核心图集首次创建和重生成都必须严格提交恰好四张 canonical 切片；alpha、可见像素、规范像素唯一、Canvas resource/asset identity 唯一任一不满足即失败。旧项目补登记与已有完整登记都必须由客户端私有回执交叉验证，不能把可编辑公开清单或顶层 manifest 中的自述身份单独升级为权威源；部分登记要么按私有回执事务补全，要么明确 warning。规范图只作 reference，不再计为运行态平台素材。
+- 隐私投影：成功结果中的普通 warning 与 slice warning 也必须逐条经过宿主路径、凭据、URL 脱敏及长度限制，不能只保护错误分支。
+- 权限边界：开放的是 `regenerate / registered resources / playtest` 等产品语义，不是原始最高权限。`regenerate` 只由当前请求最新一条原始 User 消息授权并绑定客户端稳定 `clientTurnId`；模型参数、MCP 自动批准和缺失 clientTurnId 都失败关闭。授权输入先对完整原文做 Unicode NFKC 与撇号规范化，随后整串必须完整匹配审核过的独立立即执行指令，只允许句号/感叹号收尾；不得剥离引号、方括号或代码片段，动作前后也不得携带 brief、条件、否定、选择、确认、费用、延迟或其它文本。复杂风格需求先单独描述，再由下一条独立确认消息授权，不能用开放式 deny 词表推断付费同意。同一进程重复水合相同 stable turn 时，“回合仍在运行”只作为非终态占用提示，不得以该 turn 的稳定 assistant messageId 持久化并覆盖原执行结果。DirectProject 的 cwd、sandbox writable root 与文件批准根只允许 canonical 且非 symlink/reparse point 的真实 `game/`，canonical 项目根的原生 OS 路径字节和权威 manifest `projectId` 经域标签及独立长度前缀编码后共同绑定连接池与 thread 身份；项目根、`assets/`、`.agent/` 不可写，网络关闭，命令、MCP 扩权和额外权限批准全部拒绝。受控 `agc_tools` 只在客户端内部从同一真实 `game/` cwd 反查已校验的 canonical 项目根，不把项目根加入 Codex writable roots。Codex 不获得任意 Tauri invoke、Token/Key/Cookie；`resources` 也只投影稳定身份与相对路径，不返回 prompt、provider route、URL 或绝对路径。
+- 验收边界：程序证明切片真实 alpha、可见像素、内容唯一、稳定身份和实际渲染；背景语义、无缝地面、实体含义与绘制尺寸继续由工具图片和双视口试玩验收，不把 prompt 描述外推为视觉事实。game-chat 的有效旧包语义替换仍是独立 replace route，不能复用 Direct 开关或伪装为 missing。
+- Direct 恢复 claim：同一 App 实例重复水合相同 stable turn 并收到“仍在运行”时，必须释放该 `projectPath + clientTurnId` 的恢复 claim，且不得写稳定 assistant 终态。后续显式刷新对话可按原身份重新读取或续跑；不新增无界自动重试。
+- 严格图集崩溃收口：workflow 在严格图集调用前先持久化 `strictSpritesheetPending` 并冻结底层严格事务覆盖的九项旧合同身份；旧路径可精确冻结为缺失。Provider 完成结果先绑定原 retained stage ledger。恢复在同一项目锁内对账严格事务；只有新九项合同、规范图/背景图替换锚点与 retained spritesheet result 三者一致才补写 `completed`，旧九项合同才允许补偿。旧合同判定、写 `compensating`、恢复两项素材与登记、回读和清锚点必须在同一项目锁内，重启已有 `compensating` 也重新判定；第三种混合、漂移或 foreign result 状态进入 reconciliation。不能在主图集与四切片已整体提交后仍按两文件 rollback 制造混合包；若中断前阶段告警尚未进入 durable completed result，恢复结果追加“原阶段告警无法完整重放”的明确 warning，不静默清空。
+- Direct 对话恢复从新到旧扫描全部合法 User 回合，遇到较新已回答回合继续向前，不得丢失更早未回答回合。成功返回时 Rust 已先持久化 assistant，前端冗余 append 失败也不得重跑 Provider；普通错误终态的显式 append 失败后，恢复 claim 必须保持到 React fallback writer 对同一稳定 assistant messageId 的写入明确成功或失败，不能在 writer 尚在途时按旧 `/history` 快照重跑。fallback 成功后释放 claim；fallback 失败时跳过该 writer 的无界迟到重试并释放 claim，后续显式 `/history` 才可复用原稳定 `clientTurnId`。终态收敛后删除 claim，避免长会话无界增长。

+## Direct 美术工具不能把“包存在”当成“本次已生成”（2026-08-23）
+
+- 现象：用户明确要求重做美术或切换游戏主题，工具仍立即返回 `assets/art-spec.png`、`assets/direct-game-background.png`、`assets/art-spritesheet.png`；新需求没有 Provider operation，游戏继续使用旧图。切片虽然已经落盘，也可能不出现在资源管理或工具结果中。
+- 原因：旧 Direct 工具只有 `brief`，完整包校验成功后无条件短路；固定阶段账本恢复又未比较本次生成 prompt。切片只写文件和切片清单，未作为顶层 manifest asset 投影；工具桥只返回三条主路径并丢失切片与 warning。
+- 处理：显式重做使用 `mode=regenerate`，普通请求使用 `reuse-or-create`。重生成必须由当前最新 User 消息明确授权并绑定客户端稳定 `clientTurnId`。授权先对完整原文做 Unicode NFKC 与撇号规范化，随后整串必须完整匹配审核过的独立立即执行指令，只允许句号/感叹号收尾；不得剥离引号、方括号或代码片段，动作前后也不得携带 brief、条件、否定、选择、确认、费用、延迟或其它文本。风格需求先单独描述，再由下一条独立“请重新生成美术”消息确认；不要靠扩充 deny 同义词推断付费同意。同一调用完成回包丢失只从 `completed` 持久结果等值重放，不能因重试再次扣费。App 必须在 Direct 调用前落盘原始 User 消息和回合 ID，Tauri 必须在成功返回前幂等落盘同 ID assistant 终态；同进程重复水合若命中“回合仍在运行”，只能显示瞬时占用提示，不得以稳定 assistant messageId 写成终态并抢占原执行的成功回复。恢复扫描与启动前置恢复必须发现 `resetting / compensating / anchored in-progress` 并在专用锁内恢复，重开项目只续跑真正未回答的原身份。整条付费链必须持有专用跨进程执行锁；换新回合时先持久化 `resetting` 再清理旧阶段账本，不得通过删除 workflow 留出无主窗口。崩溃补偿只恢复旧文件并清 replacement CAS 锚点，已 `prepared / accepted` 阶段账本、原 `Idempotency-Key / operationId` 必须保留，同冻结意图续跑复用旧请求；未知账本在文件 mutation 前失败关闭。只有没有任何阶段账本和替换锚点的孤立 workflow 空壳可原子接管；旧 schema 和其余冲突失败关闭。遇到 prompt 或当前 art-spec 身份不一致的未决账本必须保留原 operation 并返回对账错误。Direct app-server 可写边界只限真实 canonical `game/`，canonical 项目根的原生 OS 路径字节与权威 manifest `projectId` 经域标签和独立长度前缀编码后共同绑定连接池和 thread 身份，不得写项目根、`assets/`、`.agent/`，也不得获得网络、命令、MCP 或权限扩权；受控工具如果需要项目级客户端状态，只能从同一真实 `game/` cwd 经相同校验内部反查项目根，不能扩大模型可写根。标准图集首次创建和重生成都要求四张透明、可见、像素及平台身份唯一的 canonical 切片；工具只回传通过私有回执、公开清单、源图和顶层登记交叉验证的 `slicePaths` 与安全 `resources`。部分/opaque/重复/缺回执切片必须告警，不能把公开清单或顶层自述身份当作 Canvas 权威。
+- 验收：不要把规范图当运行态素材，也不要用 prompt 证明图片内容。程序门检查透明/可见像素、唯一性、来源、登记和源码/双视口渲染；背景排除实体、无缝地面、管道或角色尺寸等仍需观察返回图与真实试玩截图。Direct 修复不能外推为 game-chat 已支持有效旧包强制替换。
+- 同进程恢复补充：命中“同一 stable turn 仍在运行”后除禁止写 assistant 终态外，还必须删除当前 App 实例的恢复 claim。这样原调用随后成功时显式刷新能读取其终态，随后失败时也能按相同 `clientTurnId` 再次续跑；不要靠重载 WebView 清理进程内 claim，也不要用无界定时轮询制造并发调用。
+- 严格图集崩溃补充：规范图和背景图的两文件 rollback 不覆盖严格图集事务已经整体修改的 `.agent/manifest.json`、私有回执、公开清单、主图集、四切片和切片清单。必须在严格调用前持久化 pending 及九项旧合同身份；重启恢复先对账底层严格事务，完整新合同直接收口完成，完整旧合同才补偿前两阶段，混合或漂移状态失败关闭。不要在严格提交成功后局部恢复前两张图。
+- 部分旧包补充：rollback 的规范图/背景图必须保存旧字节与旧 manifest entry，不能把这两项缺失隐式当成空内容；显式 `regenerate` 因此只在这两项可信可回滚时开放。历史主图集、私有回执、公开清单或 canonical 切片可以缺失，但八个严格路径与受管顶层 asset identity 必须逐项冻结其真实 `Present/Some` 或 `Missing/None` 状态，补偿也必须恢复相同存在性。不要因为旧美术包缺切片而阻断重生成，也不要把本轮新建的严格文件误记成旧文件。
+- 对话扫描与 claim 补充：历史中出现 `User A / User B / Assistant B` 时，B 已回答不代表 A 已回答，扫描必须继续寻找 A。成功 Direct 回复在 Rust 返回前已经落盘，前端冗余 append 失败不能据此重跑；普通错误回复的显式落盘失败时，恢复 claim 要保持到 React fallback writer 的同一 messageId append 明确收敛。writer 成功或明确失败后才释放；失败路径要停止该消息的自动迟到重试，再由显式 `/history` 复用原 stable turn。终态后及时删除 claim，避免 Set 无界增长。

+- 工具完成结果同时返回主包 `assetPaths`、实际成功持久化的 `slicePaths`、安全身份投影 `resources`，并把普通 `warnings` 与 `sliceWarnings` 分开。每张本地切片都以真实 Canvas `resourceId / assetObjectId / taskId` 和源图集 `sourceResourceId` 登记为顶层 manifest asset；同路径替换保留本地 asset ID。严格图集事务继续覆盖主图、四张 canonical 切片、公开切片清单、私有回执和 `.agent/manifest.json`，失败时整组恢复。旧项目缺顶层切片登记时只能由客户端私有回执授权补登记；可编辑的公开切片清单不能单独成为 `.agent` Canvas 身份来源。
+- `regenerate` 授权只取当前请求中最新一条原始 `role=User` 消息，并绑定外层稳定 `clientTurnId`；引号或代码中的按钮文案/示例、历史消息、模型自行填写的 `mode`、MCP 自动批准和缺失 clientTurnId 均不能形成付费替换授权。授权判定先对完整原文做 Unicode NFKC 与常见撇号规范化，随后整串必须完整匹配审核过的独立立即执行指令，只允许句号/感叹号收尾；不得剥离引号、方括号或代码片段，动作前后也不得携带 brief、条件、否定、选择、确认、费用、延迟或任意其它文本。复杂风格需求必须先在非付费消息中描述，再由下一条独立“请重新生成美术”确认消息签发授权；不能靠开放式 deny 词表猜测当前付费同意。工具桥只保留授权判定和摘要，不保存或回传用户原文。同一进程重复水合相同 `clientTurnId` 时，“回合仍在运行”只属于瞬时占用状态，前端不得以稳定 assistant messageId 将其写成终态；原执行的成功回复仍由 Tauri 在返回前持久化。DirectProject app-server 的 cwd、sandbox writable root 和文件变更批准根统一收窄到经 canonical 校验且非 symlink/reparse point 的真实 `game/`；canonical 项目根的原生 OS 路径字节与权威 manifest `projectId` 通过域标签和各自长度前缀编码后共同进入 Direct 连接池和 thread 身份，稳定符号链接改指其它项目、同路径重建项目、不同非 UTF-8 路径或内嵌 NUL 的项目 ID 都不能复用旧连接。项目根、`assets/` 与 `.agent/` 不可写，网络关闭，命令执行、MCP 扩权和额外权限申请一律拒绝。受控 `agc_tools` 子进程只能从同一真实 `game/` cwd 经相同权限校验反查 canonical 项目根供客户端内部桥使用，不能把该根加入 Codex writable roots。`resources` 只返回本地 asset/path/kind/media type、Canvas project/resource/asset/task ID 与 reference resource IDs，不返回 prompt、model、provider route、绝对路径、URL、Token、Cookie 或 API Key。
+- 成功响应中的 `warnings / sliceWarnings` 与错误响应采用同一脱敏边界：逐条移除宿主绝对路径、凭据与 URL，并设置固定长度上限；非阻断告警不成为绕开错误分支隐私保护的旁路。
+- Direct 同进程重复水合若收到“同一 stable turn 仍在运行”，必须释放当前 App 实例的恢复 claim；该结果不落 assistant 终态，后续显式刷新对话可按原 `clientTurnId` 再次读取已落盘回复或续跑，不要求重载整个 WebView，也不启动无界自动轮询。
+- 对话恢复从新到旧扫描全部合法 Direct User 回合；较新的 User 已有稳定 assistant 时必须继续寻找更早未回答回合，不能提前结束扫描。普通成功回复或普通错误回复若终态 assistant 持久化失败，同样必须释放当前 App 实例的恢复 claim，使后续显式 `/history` 能以原稳定 `clientTurnId` 重试；claim 只表示当前实例内正在恢复，不能成为磁盘终态的替代品。
+- Direct 的运行态素材验收不再把 `assets/art-spec.png` 当作背景、角色、道具或反馈；规范图只作为派生 reference。标准核心图集无论首次创建还是显式重生成，都必须原子取得恰好四张 canonical 独立切片后才算本次生成成功；每张切片必须有真实 alpha、可见像素、唯一规范像素内容及唯一 Canvas `resourceId / assetObjectId`。旧项目只在私有回执与公开清单、当前源图和顶层登记完全一致时投影四条 `slicePaths`；部分、opaque、重复或缺回执状态只返回 warning，不得猜测或伪造衍生素材。
+- 机器门只证明 PNG、真实 alpha、非空可见像素、切片像素唯一、稳定平台身份、顶层登记及源码/双视口实际渲染。背景是否混入实体、地面是否无缝、素材语义是否匹配、最终绘制尺寸是否满足玩法仍由 Codex 检查工具图片和 desktop/mobile 试玩截图；prompt 约束本身不算通过证据。
+- 本节只修 Direct Codex 工具链。`project-supervisor-game-chat` 对“已有有效包但用户显式要求视觉替换”的 replace route 仍需独立 Goal Contract 与授权设计，不能把语义不兼容伪装为结构缺失，也不在本次变更中放宽。
