+- Platform provenance and manifest resource identity come only from approved client tools. Project-file discovery may report an unregistered path, but that path has no provenance until a client import/register transaction succeeds.

 - Browser evidence proves runtime behavior, not resource ownership.

 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. 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.

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.

 - `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 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.

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.

+- 素材读取区分三类来源：`asset.list` / `agc_list_registered_assets` 是当前项目本地 manifest，`agc_list_project_files` / `file.list` 只发现项目目录中实际存在但可能未登记的文件，`asset.library.list` 是当前登录账号素材库，项目画布资源读取是当前网页项目/画布的完整图片清单；账户素材库不能替代项目画布清单。
+- Agent 只接收稳定素材 ID、类型、尺寸和项目相对路径等安全投影。客户端负责重新校验账号/项目归属、换签下载、媒体校验，以及 manifest/画布原子登记；不得向 Agent 暴露绝对路径、签名 URL、objectKey、token 或 Cookie。
+- `canvas.asset_import` 支持账户/画布资源 ID 和项目内本地相对路径。项目文件发现结果以 `assetImportable` 明确区分当前可登记的 PNG/JPEG/WEBP 与仅可发现的 GIF/SVG/其它媒体，Agent 只能提交前者。导入拒绝路径穿越、`.agent`、符号链接/reparse point 及敏感配置文件；外部宿主文件须由 UI 原生文件选择器授权后导入，不开放任意绝对路径。
+- Runtime `asset.list` 与 `file.list` 的详情使用文件上下文上限，而不是普通工具短摘要上限，确保有界候选/目录清单不会因前部内容较长而整体丢失；`asset.list` 超出 48 项或 `file.list` 超出 40 项时仍显式返回剩余数量，Agent 再按候选父目录（例如 `assets`、`game/assets`）缩小范围查询。
+- 结果仅返回成功/跳过/失败数量、安全 ID、相对路径、来源、脱敏失败摘要和实际 `revisionAdvanceCount`；幂等跳过不得虚增 revision，部分失败仍须准确记录已发生的 revision 变化。
+- 普通 Prompt 上下文与错误诊断必须使用分离的脱敏边界：Prompt 继续对疑似凭据行整体隐藏；错误诊断保留 HTTP 状态以及 `code / field / message / reason / detail` 等安全字段，仅替换 Token、Cookie、私钥、配置名、URL 和宿主路径等敏感值。`agc_create_or_derive_resource.assetName` 是必填的人类可读资源显示名称，不接受项目路径、URL、objectKey、Token 或其它凭据。

 - `agc_tools` 新增 `agc_list_registered_assets` 与 `agc_create_or_derive_resource`。前者按 `kind / assetId / offset / limit` 有界查询客户端权威 manifest，并可显式返回角色动画正式序列帧的稳定 objectKey、assetObjectId 和尺寸；结果不包含完整 manifest、prompt、model、provider route、签名 URL、宿主路径或凭据。后者只接受 `kind / mode / sourceLocalAssetId / prompt / assetName`，`create` 仅允许无源视频、音效和背景音乐，`derive` 必须引用当前项目已登记的 localAssetId，角色动画固定为 derive。
