+## 2026-09-24 UI 设计文档三个工具的持久回执明细与入参摘要改为可读白名单
+
+- 背景：动作回执的"安全明细"是一份白名单——只有认识的工具才把明细整理成安全字段。`ui.workflow.run` 退役时删掉了它那段分支，接管的 `ui-design-doc.*` 三个工具没补，于是统一落到兜底：明细整块变成 `detailUnavailable`，模型与审计都看不到；入参那一栏也只剩哈希。原始明细既不落盘也不给模型，所以**没有宿主路径泄露**，丢的是可用性（例如切分没登记上的素材清单）。
+- 决策：按既有白名单口径给三个工具各补一条分支。`from-images` 放 `assetId` / `relativePath` / `imageIds` / `revisionAdvanceCount`；`run-workflow` 再放文档 `revision`、恢复标记、识别与绑定计数、`backfillErrors` 与总数；`into-js` 只放相对路径与计数（导出名清单只用来核对数量，不逐项外传）。
+- 决策（校验口径）：身份字段走 `agent_runtime_action_receipt_identity_text`（禁控制字符、限长、含 file URI 或绝对路径即失败关闭）；相对路径必须归一化后落在 `ui/` 下；回填说明是自由文本，按既有口径把绝对路径脱敏成占位符，含控制字符或超长则整条明细失败关闭。
+- 决策（体积）：回执明细总长仍受 `AGENT_RUNTIME_ACTION_RECEIPT_SAFE_DETAIL_MAX_CHARS`（500）约束。设计图身份与回填说明按长度上限能放多少放多少，放不下的部分用 `backfillErrorCount` 表达总数；必需字段本身就超限时整条明细不可用。
+- 决策（入参摘要）：`agent_runtime_tool_action_input_summary` 为三个工具产出可读摘要（设计图逐张身份或目标文档 id），并把工具名加进 `agent_runtime_public_action_input_summary` 的可读名单，不再退化成只报哈希。
+- 验证方式：`tests::runtime_actions::action_execution::ui_design_doc_receipts_*` 两条用例（三个工具都能留下可用明细且不超长；宿主路径被脱敏；`ui/` 之外与宿主路径身份失败关闭）与 `action_audit::ui_design_doc_public_input_summary_tests` 两条用例；`cargo test --bin genarrative-ai-game-creator-shell receipt` 55 条全绿。

 ## 2026-09-24 UI 设计文档三个工具纳入项目变更门禁（成功返回即算改过项目）
 
 - 背景：`ui.workflow.run` 退役时，项目变更门禁的两处工具名单（`agent/runtime_actions/project_gates.rs` 的 `is_agent_runtime_project_mutation_observation` 与 `agent_runtime_observation_advances_project_revision`）只删未补，新接管的 `ui-design-doc.from-images` / `ui-design-doc.run-workflow` / `ui-design-doc.into-js` 都没登记。后果：改完项目可能被判定"没改过"，于是不要求验证就判完成、自动模式的 liveness 判据看不到进展；`agent_runtime_pending_expected_project_revision` 少算推进量又会误报 `pending_project_revision_drift`（"并行项目变更使旧动作过期"）。
