 最新增量证据（2026-08-14）：
 
+- D-314/ADR-0406（已接受）：Cluster Trusted Tool 的 encrypted completion 不再停留在 storage port。`@qinglong/cluster-control/trusted-tool-result-keyring` 新增只读 projected material authority：canonical v1 manifest 只含最多 16 个 canonical 32-byte key，不含 generation、active/state/retirement，provider 只有 `resolve(keyId)` 而没有 `active()`；因此 PostgreSQL `trusted-tool-results` catalog 仍是 active/decryptable 状态唯一 authority，completion 会以 catalog material proof 再次校验。runtime 每次调用重新执行 direct-root、in-root atomic symlink、single-link、64 KiB、只读/不可执行/other-inaccessible mode、dev/inode/size/mtime 与双 realpath fence，不持有 Kubernetes API、cache、watcher 或 timer。新增能力位于 Cluster Control 既有 `trusted-tool/key-management/`，并把 mounted Secret 与 keyring 的 projected-file/TOCTOU 逻辑收敛到 package-private `security/privateProjectedFile` 真源；公开 mounted Secret 行为不变，不新增 package、依赖、migration、连接、route 或默认 Profile importer。定向共享回归 7/7，Cluster Control 完整 234 pass/2 条条件 skip/0 fail；最终 18-package clean build/test 与 backend 1,207 pass/2 条件 skip/0 fail，package/dependency/Edge import/Cluster deployment 四项审计零 finding。workspace 仍为 18 package、无单文件或浅平 package；Cluster Control 54 个源码中仅 2 个 binary entry 位于根层，52 个处于嵌套领域目录。14 档 Local Profile artifact 全部通过，默认 Edge/Standalone 保持 2,589,812/2,589,890 bytes，AI 保持 3,121,108/3,121,198 bytes，MCP 保持 7,315,930/7,316,038 bytes。PostgreSQL 18.4 arm64 HA 125/125、timeline `1→2`，报告 SHA-256 为 `26c817647ed984d8d4627a7cae1c95de06017a5d6d32dd3dfd01414ba029e542`，证据审计与 Docker 容器/网络/卷零残留。下一 Gate 是独立 diagnosis Run 的 Tool/Model Step admission 与 Copilot encrypted model completion，不能借用终态源 Run 或 Plugin Prompt plan。
 - D-313/ADR-0405（已接受）：新增 `@qinglong/ai/failure-diagnosis-prompt`，把 ADR-0403 的潜在敏感日志投影收敛为固定 system instruction + canonical JSON data envelope；日志只存在于 `log.content` JSON string value，不能通过引号、换行、伪造 role/schema 或 delimiter 拼接出新 message。builder 重新校验完整 trust/redaction/profile byte 契约，拒绝伪造 `safe`、行动权、未知字段与 byte/signal drift；envelope 不带 Run/Attempt、Artifact、path、cursor 或 content digest。部署者必须通过 `qinglong/copilot-model-egress-policy@v1` 显式允许 `potentially_sensitive` 数据进入 `on_device|external` 边界并提供输入/output token 双预算，空 allowlist 与 external 未授权均在 Model Gateway/Provider I/O 前失败关闭。输出只含 content-free egress evidence，并固定要求模型 completion 继承潜在敏感、仅加密持久化、禁止明文审计且无行动权；真正 Cluster Trusted Tool/model completion 仍需后续组合门。能力以 `ql3-ai/src/copilot/failure-diagnosis/` 三个内聚文件和精确 subpath 交付，不新增 package、依赖、迁移、连接或常驻组件。定向 12/12、AI 221 pass/3 条件 skip/0 fail；最终 18-package clean build/test 与 backend 1,207 pass/2 条件 skip/0 fail，四项结构/部署审计零 finding，14 档 Local Profile artifact 全部通过。默认 Edge/Standalone 保持 2,589,812/2,589,890 bytes、315 files、56 modules，Edge/Standalone AI 保持 3,121,108/3,121,198 bytes、368 files、61 modules，MCP 保持 7,315,930/7,316,038 bytes、801 files、226 modules，证明未装配 subpath 被完全裁掉。PostgreSQL 18.4 arm64 HA 125/125、timeline `1→2`，报告 SHA-256 为 `2bbc8bdd0d90e6ec9ce82d2afcaec817679dddb82860c5d405a09d5e5458bece`，证据审计与 Docker 零残留。

+# ADR-0406：Cluster Projected Tool Result Key Authority
+
+- 状态：Accepted
+- 日期：2026-08-14
+- 关联 RFC：QL-RFC-0001 D-314、Phase 2
+- 关联 ADR：ADR-0163、ADR-0164、ADR-0166、ADR-0263、ADR-0403、ADR-0405
+
+## 问题
+
+ADR-0163~0166 已完成 Trusted Tool 成功结果的加密 Artifact、PostgreSQL catalog fence、rotation/
+rekey/retirement 协议和双方言 repository；Cluster runtime 也已经从同一 Pool 装配 completion、catalog
+与 rekey storage。但产品组合只有 storage port，没有可部署的 result-key material provider，因此
+ADR-0405 的日志 Tool 还不能在 Cluster 中兑现 encrypted completion。
+
+直接复用 Plugin Package Prompt output keyring 会混合两种密文域和轮换 ceremony；让投影文件携带
+`activeKeyId` 又会与 PostgreSQL `trusted-tool-results` catalog 形成双 active authority。把 key 写入环境
+变量、数据库或常驻缓存，则分别失去文件权限/轮换证明、违反数据库不保存 material 的约束，或引入撤权
+窗口。该能力也不足以形成新的部署制品或 workspace package。
+
+## 决策
+
+1. 在既有 `@qinglong/cluster-control` 的 `src/trusted-tool/key-management/` 中增加 Cluster Tool Result
+   projected keyring，并只通过精确 subpath `trusted-tool-result-keyring` 导出。它不进入 package root、
+   默认 control composition、Edge/Standalone 或普通 Worker closure。
+2. manifest 固定为 `qinglong/cluster-tool-result-projected-keyring@v1`，只含 canonical `keys` map；key ID
+   沿用 Runtime Core catalog 约束，material 必须是 canonical base64url 的 32 bytes。投影最多包含 16 个
+   key，与 catalog 的最大 decryptable key 数一致；文件最大 64 KiB 且必须是单行 canonical JSON 加换行。
+3. manifest **没有** generation、active key、state、retirement 或恢复字段。provider 只实现 `resolve(keyId)`，
+   不实现 `active()`；当前加密 key 与历史可解密状态只能由 PostgreSQL catalog 的 generation/digest/
+   material proof fence 决定。投影文件增删 key 不能自行改变 durable catalog 状态。
+4. `verify()` 只返回 key ID、Runtime Core domain-separated material proof 和整个投影的 content-free digest，
+   不返回 encoded/raw material。Trusted Tool completion 仍会在每次使用时以 catalog entry 的 proof
+   重新校验 material，调用完成后由既有 coordinator 清零 owned key bytes。
+5. runtime 每次 resolve 都重新打开投影，不使用 Kubernetes API、ServiceAccount、list/watch、cache、timer
+   或后台进程。允许 Kubernetes atomic-writer symlink，但 resolved regular file 必须留在 direct、非 symlink
+   root 下；同时校验 single-link、大小、只读/不可执行/other-inaccessible mode、dev/inode/size/mtime 和
+   root/target 二次 realpath，轮换竞争失败关闭。
+6. Cluster Control 内原有 mounted Secret provider 与新 keyring 共享 package-private
+   `security/privateProjectedFile` primitive。原公开类、错误码、文件名、大小和权限语义不变；抽取消除两套
+   TOCTOU/symlink 实现，后续安全修正只有一个真源。该 primitive 不新增公开 export。
+7. 本阶段不增加环境变量、volume、route 或 AI 启动前置条件。只有后续 Cluster Copilot composition 明确
+   启用并把该 provider 与 PostgreSQL catalog、Trusted Tool coordinator 连接时，部署者才需要投影它；
+   adapter 存在不等于执行 authority 已开放。
+
+## 低配与集群影响
+
+- 默认 Edge/Standalone 和默认 Cluster Control 没有新 importer、listener、连接、timer、watcher、cache、
+  migration、表或常驻内存；workspace 继续保持 18 个 package。
+- Cluster AI 后续只在一次 Tool completion 时读取最多 64 KiB 的一个 manifest，内存 key 数硬限 16；
+  PostgreSQL 继续是 active/decryptable state 的唯一事实源。
+- 实现使用既有 package 的嵌套领域目录，不创建单文件 package，也不把文件平铺到 `src/` 根。
+
+## 被否决方案
+
+1. **复用 Prompt output keyring/root**：跨加密域复用 material 与 rotation ceremony，扩大单 key 泄露半径。
+2. **manifest 自带 activeKeyId**：会让文件和 PostgreSQL catalog 同时选择 active generation。
+3. **把 raw/wrapped key 放进 PostgreSQL**：违反 ADR-0166 的 catalog/material 分离与数据库最小泄露面。
+4. **使用环境变量或进程缓存**：缺少轮换文件身份，且产生撤权窗口和长期明文驻留。
+5. **为 provider 新建 workspace package**：没有独立进程、制品、权限角色或第二个生产 consumer。
+6. **复制 mounted Secret 的安全读取代码**：会让 symlink、mode 与 TOCTOU 修复发生行为漂移。
+
+## 当前验证
+
+1. 新增 3 项 keyring 测试，覆盖无 `active()` authority、material proof、owned bytes、原子投影轮换、
+   historical/missing key、非 canonical JSON、错误 key 长度、可写文件、逃逸 symlink、symlink root 和路径逃逸。
+2. 共享 projected-file 抽取与既有 mounted Secret 回归合计 7/7；Cluster Control 完整测试为
+   234 pass、2 条 PostgreSQL/S3 条件 skip、0 fail。
+3. `pnpm run test:packages:ql3` 完成 18-package clean build/test；完整 backend 为 1,207 pass、2 条
+   条件 skip、0 fail。package boundary、Cluster dependency、Edge import 与 Cluster deployment 四项审计
+   均为 compatible 且零 finding。
+4. workspace 仍为 18 个 package，无单文件或浅平 package；Cluster Control 共 54 个源码文件，只有
+   `aiCli.ts`、`cli.ts` 两个 binary entry 位于 `src/` 根，其余 52 个均处于嵌套领域目录。
+5. 14 档 Local Profile artifact 全部通过；默认 Edge/Standalone 为 2,589,812/2,589,890 bytes，
+   AI 为 3,121,108/3,121,198 bytes，MCP 为 7,315,930/7,316,038 bytes。证明新增 Cluster-only
+   subpath 没有进入低配设备的本地闭包。
+6. PostgreSQL 18.4 arm64 HA 为 125/125 Gate、timeline `1→2`；报告 SHA-256 为
+   `26c817647ed984d8d4627a7cae1c95de06017a5d6d32dd3dfd01414ba029e542`，独立证据审计零 finding，
+   Docker 容器、网络与卷零残留。
+
+## 后续门禁
+
+1. 定义独立 Copilot diagnosis Run admission，在同一诊断 Run 中创建 Tool Step 与 Model Step；不能把 Tool
+   Step 追加到已终态的源失败 Run，也不能借用 Plugin Package Prompt plan 冒充 Copilot plan。
+2. 组合 Project Tool snapshot、invocation Artifact key、S3 log reader、result-key provider 和统一 Trusted
+   Tool completion，证明 response-loss replay 不会重复执行 adapter。
+3. 将 ADR-0405 builder 与现有 Model Gateway 连接，并建立 Copilot 专用 encrypted model completion；
+   禁止把 live response、普通 model completion 或 Prompt output Artifact 冒充潜在敏感诊断完成记录。
+4. 最后才开放默认关闭的认证/Policy/audit/credential-fenced Cluster route，并补多副本 HA、真实 S3、
+   外部 Provider fault injection 与 plaintext audit negative evidence。
