 最新增量证据（2026-08-16）：
 
+- D-336/ADR-0428（已接受；公开发布结果待实际 tag）：D-335 的 90 天 workflow artifact 不再是长期唯一发布入口。完整 release set 现以单层 OCI artifact 发布到专用 `ghcr.io/<owner>/qinglong3-release-catalog`，固定 artifact/file media type、basename、四项 annotation 和 byte-exact round trip；`v<version>-<scope>` 仅作发现且 authority 明确为 `none`，部署权威是验证后的 catalog `@sha256:` immutable reference。发布后先按 digest 取回并逐字节比较、审计 raw manifest，再为该 digest 生成 exact workflow identity 的 keyless Cosign signature 与绑定 source tag/revision 的 GitHub OCI provenance；验证成功后才生成 canonical receipt 并为 receipt 增加 file provenance。release-set 新增不依赖短期 candidate/image-record 的 standalone inspect，重算结构、身份、Local/Cluster 镜像闭包与 self digest，同时显式声明未重放 source records。低配路由器可在可信工作站完成 registry/签名/provenance/Node 验真，只消费 `local` JSON 与镜像 digest，设备不增加工具、package、依赖或常驻资源；Cluster 使用同一 catalog 锁定 control、control-ai、worker、admin 四角色。真实本机 `ocidir://` 实验确认同一文件来自两个不同绝对目录时，`--file-title --strip-dirs` 产生相同 manifest digest `sha256:0443422e34edd448499a61f4580b01b9578dc35a117668c948c51a16638e4e9d`，immutable get 与源文件逐字节一致。定向发布契约/静态 workflow/Console 联动测试 93/93；backend 1282 项为 1280 pass、2 条件 skip、0 fail；18-package clean build/test 退出 0，package boundary 保持 18 packages、`singleSourcePackages=[]`、`shallowSourcePackages=[]`，release version、dependency、Edge import、Cluster/Worker deployment、image release、Local image 与 Console distribution 审计全部 compatible。14 档 Local artifact 均 compatible，默认 Edge/Standalone 为 2,589,890/2,589,968 bytes，MCP 为 7,315,930/7,316,038 bytes；Cluster Admin pack 保持 250 files、271,238-byte tarball、1,690,196-byte unpacked。本 Gate 无数据库/HA 拓扑变化，复用 D-331/D-333 PostgreSQL 18.6 arm64 142/142、timeline `1→2` 基线。公开 GHCR push、签名和 attestation 尚未执行，且 GHCR 保留/删除仍属于组织治理，因此不宣称 catalog 为 WORM 或已完成线上发布。
 - D-335/ADR-0427（已接受；公开发布结果待实际 tag）：发布矩阵不再让每个镜像验证成功后独立写 version/source tag。每个 publisher 只产生不可变 digest，在远端 manifest、Cosign、四类 GitHub attestation 与适用的 Local rollout 全部验证后生成绑定同一 candidate/scope/source/owner/repository/platform/digest 的 canonical image record；唯一 release-set 终态 job 只在完整 publish matrix 成功后下载 exact `run_id/run_attempt` record，重新生成 candidate，并要求 Local 一镜像、Cluster 四镜像或 All 五镜像集合无遗漏、无重复、顺序一致。独立审计通过后才统一 promotion，写前回读全部 source digest/既有 tag、冲突失败、缺失才 copy、写后再验 digest；明确不宣称 GHCR 跨仓库原子性，以 `verify_exact_digest_then_continue` 支持同源幂等恢复。最终 `qinglong/release-set@v1` 同时冻结 deployment family、五类可选镜像、image-record digest 和 `@sha256:` 引用，获得 GitHub file provenance 并作为 90 天 deployment digest-lock artifact 发布。Edge/Standalone 只消费 `local` set，Cluster 只消费四角色 set，`all` 不把两族运行时耦合；不新增 package、生产依赖、Pod、controller、listener、timer、watcher、数据库、migration、SQL、Pool 或低配设备常驻开销。定向 contract/workflow 回归 73/73，联动发布/Console distribution 回归 77/77；backend 1,264 pass/2 条件 skip/0 fail，18-package clean build/test 退出 0，package boundary 保持 18 packages、`singleSourcePackages=[]`、`shallowSourcePackages=[]`，dependency、Edge import、Cluster/Worker deployment、image release 与 Local image 审计均 compatible。14 档 Local artifact 全部 compatible，默认 Edge/Standalone 精确保持 2,589,890/2,589,968 bytes、315 files、56 modules，application+AI 为 4,493,043/4,493,175 bytes，MCP 为 7,315,930/7,316,038 bytes；Cluster Admin pack 保持 250 files、271,238-byte tarball、1,690,196-byte unpacked。本 Gate 无数据库/HA 拓扑变化，复用 D-331/D-333 PostgreSQL 18.6 arm64 142/142、timeline `1→2` 基线；公开 tag 尚未执行，因此不宣称真实 GHCR promotion 或线上 attestation 已成功。

+# ADR-0428：持久化 OCI Release Catalog 与独立部署验真
+
+- 状态：Accepted
+- 日期：2026-08-16
+- 关联 RFC：QL-RFC-0001 D-03、D-14、D-333、D-334、D-335、D-336
+
+## 上下文
+
+ADR-0427 已用 canonical `qinglong/release-set@v1` 闭合一个 deployment family 的全部镜像 digest，
+但唯一分发路径仍是保留 90 天的 GitHub Actions artifact。稳定版本可能在该窗口之后才部署或恢复；同时，原
+release-set 完整审计依赖同一次 workflow attempt 的短期 image record，部署者无法在记录过期后独立复验文件的
+结构、身份与自身 digest。
+
+低配路由设备不应为了发布验真安装 registry、Cosign、GitHub CLI 或 Cluster 依赖；Cluster 运维者则必须从同一个
+可发现入口得到 control、control-ai、worker、admin 四个角色的完整 digest lock。两类部署需要同一发布事实，但不应
+承担相同的本机工具和运行时成本。
+
+## 决策
+
+1. 成功生成并完整审计 release set 后，发布 workflow 把原始 canonical JSON 作为单层 OCI artifact 发布到独立的
+   `ghcr.io/<owner>/qinglong3-release-catalog` repository。artifact/file media type 固定为
+   `application/vnd.qinglong.release-set.v1+json`。
+2. 发现入口固定为 `v<version>-<scope>`，但 discovery tag 的 authority 明确为 `none`。部署与恢复只接受解析并验证
+   后的 `ghcr.io/<owner>/qinglong3-release-catalog@sha256:<manifest-digest>`；不能把 tag 直接写入生产 rollout。
+3. publication plan 必须绑定 source repository、release identity、release-set self digest、内容 SHA-256、字节数、
+   确定性 basename、OCI media type、四个精确 annotation 与恢复策略。publisher 必须同时使用 `--file-title` 和
+   `--strip-dirs`，禁止 runner 的绝对临时路径进入 layer title，从而保证跨 runner manifest digest 确定性。
+4. 发布后必须从 immutable catalog reference 按确定性 filename 取回文件并逐字节比较，再读取 raw manifest。契约只
+   接受一个 exact layer、empty OCI config、预期 title/annotation、内容 digest/size 和 raw manifest SHA-256。
+5. catalog immutable digest 必须获得 exact workflow identity 的 keyless Cosign signature 与绑定 source tag、source
+   revision 的 GitHub OCI provenance，并在生成 receipt 前完成远端验证。canonical
+   `qinglong/release-catalog-receipt@v1` 冻结 plan、manifest digest、immutable reference 和验证结论；receipt 本身再获得
+   GitHub file provenance。
+6. release-set 新增独立 `inspect` 模式。它无需已过期的 candidate/image-record 文件，仍会 exact-shape 校验 release、
+   scope、owner、镜像集合、双架构、全部 digest reference、Local/Cluster family，并重算 self digest。结果必须显式
+   声明 `sourceRecordsReplayed=false`，不能冒充发布阶段的完整 source-record replay。
+7. 90 天 workflow artifact 继续作为便利 bundle，包含 release set、catalog plan 和 receipt；它不再承担长期唯一归档
+   职责。OCI catalog 也不被宣称为 WORM：组织仍须保留 GHCR package/repository 的读取权限和保留策略，发布 workflow
+   不获得删除 catalog 的 authority。
+
+## 部署与资源影响
+
+- Edge/Standalone 的推荐路径是在可信维护工作站解析 discovery tag、验证 immutable catalog 的 Cosign/GitHub
+  provenance、取回并独立 inspect `local` release set，然后只把 canonical JSON 和其中的 Local image digest 交给
+  设备。设备无需安装 Node、regctl、Cosign、GitHub CLI、Kubernetes 或 PostgreSQL 依赖，运行时 artifact、模块数和常驻
+  内存保持不变。
+- Cluster 运维者用相同 ceremony 验证 `cluster` release set，并要求 control、control-ai、worker、admin 四个角色精确
+  闭合。catalog 只存在于外部 registry 与短生命周期发布 CI，不增加 Pod、controller、listener、timer、watcher、Pool、
+  schema、migration 或 SQL。
+- `all` 仍只是同时发布两族的维护者入口；设备按所选 deployment family 消费，不因 catalog 耦合 Local 与 Cluster
+  运行时。
+
+## 恢复模型
+
+同一 source/version/scope 重跑时允许向 discovery tag 重发相同内容，但每次都必须重新解析 tag、按 immutable digest
+取回、逐字节比较并完成签名与 provenance 验证。若 tag 被外部改写，旧 receipt 中的 immutable reference 仍是历史部署
+事实；新部署不得信任 tag 的当前值，必须重新执行完整验证并取得新的 receipt。registry 删除、repository visibility 或
+组织 retention 变更属于外部治理事件，不能由 release contract 隐藏。
+
+## 被拒绝的替代方案
+
+### 仅延长 Actions artifact retention
+
+拒绝。它仍把长期部署入口绑定到 workflow run 生命周期，且不能提供 registry-native 的 immutable discovery 与
+signature/provenance 验证。
+
+### 让 discovery tag 成为部署 authority
+
+拒绝。tag 可被改写，不能替代 manifest digest；它只能帮助发现候选 immutable reference。
+
+### 在路由器上执行完整供应链工具链
+
+拒绝。验证可以在可信工作站完成。把 registry、签名与 GitHub 客户端带入低配设备会扩大镜像、内存、网络和密钥面，
+但不会增强设备实际消费的 digest lock。
+
+### 增加常驻 release-catalog 服务
+
+拒绝。OCI registry 已提供所需的存储、digest addressing 和 referrer 能力；常驻协调服务会引入新的可用性与运维故障域。
+
+## 验证
+
+- release-catalog contract 覆盖 Local/Cluster/All plan、receipt、owner/release drift、OCI media/blob/title/annotation/raw digest
+  drift、closed CLI、canonical no-replace、rename/symlink/open-mode 拒绝；release-set 同时覆盖独立 inspect 与 drift 拒绝；
+- workflow 静态门要求 standalone inspect、catalog plan、checksum-pinned regctl、`--strip-dirs`、immutable get、byte-exact
+  compare、raw manifest、catalog Cosign/GitHub provenance、先验证后 receipt、receipt provenance 和 90 天 bundle 的精确顺序；
+- 使用官方 regctl v0.11.5 在本机 `ocidir://` 进行真实实验：相同 canonical release set 从两个不同绝对目录发布时，
+  `--file-title --strip-dirs` 得到相同 manifest digest
+  `sha256:0443422e34edd448499a61f4580b01b9578dc35a117668c948c51a16638e4e9d`，按 basename 从 immutable reference 取回后
+  与源文件逐字节一致；仅使用 `--file-title` 会泄漏绝对路径并破坏该性质；
+- 定向发布契约、静态 workflow 与 Console distribution 联动测试 93/93；backend 1282 项为 1280 pass、2 条件 skip、
+  0 fail；18-package clean build/test 退出 0；release version、package boundary、dependency、Edge import、Cluster/Worker
+  deployment、image release、Local image 与 Console distribution 审计全部 compatible；
+- package boundary 保持 18 packages、`singleSourcePackages=[]`、`shallowSourcePackages=[]`；14 档 Local artifact 全部
+  compatible，默认 Edge/Standalone 为 2,589,890/2,589,968 bytes，MCP 为 7,315,930/7,316,038 bytes；Cluster Admin
+  pack 保持 250 files、271,238-byte tarball、1,690,196-byte unpacked；
+- 本 Gate 不修改 schema、migration、SQL、role、Pool、连接或 HA 拓扑，复用 D-331/D-333 PostgreSQL 18.6 arm64
+  142/142、timeline `1→2` 基线，不把未重跑的数据库门冒充本阶段新证据；
+- 本 ADR 接受源码、契约、静态 workflow 门与本地 OCI 互操作证据。公开 tag 尚未运行，因此不宣称真实 GHCR catalog
+  push、Cosign 或 GitHub attestation 已成功；它们必须由实际 release run 取得。

+

+owner='<lowercase-owner>'
+repository='<owner>/<source-repository>'
+version='<source-derived-version>'

+  --deny-self-hosted-runners
+```
+
+`inspect` 会重算 release-set self digest 并验证结构、身份、镜像闭包和 family，但不会重放发布时已经过期的 image
+records；其输出必须保持 `sourceRecordsReplayed:false`。
+
 ## 准入检查
 
-1. 只接受来自成功、未重跑替换的同一 release workflow attempt 的 artifact，并验证 release-set 文件
-   provenance。
+1. 只接受已验证 Cosign exact workflow identity 与 GitHub source tag/revision provenance 的 catalog immutable
+   reference；discovery tag 无 authority。
 2. `schema` 必须为 `qinglong/release-set@v1`；`release.version`、`release.sourceRef`、
    `release.sourceRevision`、`release.scope` 必须与变更单一致。
 3. 镜像集合必须与上表精确相等；每个 `reference` 必须是 digest reference，且 owner/repository 与部署目标一致。
 4. Kubernetes overlay 用 `newName` 加 digest 或等价的 immutable image reference；不得把生产 placeholder 改成
    `newTag`。Local compose/rollout 同样固定 `@sha256:`。
-5. rollout 前再次向 registry 解析 version/source tag。它们可以用于发现，但只有解析到 release set 的同一
-   digest 才算一致；部署仍以 digest 为准。
+5. rollout 前再次确认 catalog receipt/immutable reference 与已检查文件一致。version/source/catalog tag 都只能用于
+   发现；部署始终以 release set 中的镜像 digest 为准。
+
+## 低资源设备
+
+路由器或其他低配 Edge 设备不需要安装 Node、regctl、Cosign 或 GitHub CLI。维护者在可信工作站完成上述 ceremony，
+再向设备传输已检查的 canonical JSON，并只把 `local` family 的 immutable image reference 写入 compose/rollout。
+设备不下载 Cluster 四镜像，也不加载 Kubernetes、CloudNativePG、PostgreSQL driver 或 Worker 私有发布证据。
+
+如果设备本身不运行容器 registry client，可由工作站按 digest 拉取并通过既有离线交付渠道传送镜像；离线包的哈希与
+导入后 image digest 必须继续匹配 release set，不能退回 tag。
 
 ## 发布失败与恢复
 
 GHCR 不提供跨 repository tag 事务，release set 明确记录 `crossRepositoryAtomicity=false`。如果 promotion 中途
 失败，不删除已经正确的 tag，也不重新构建镜像。使用原 source tag/revision 重跑 release workflow：它会先验证
-每个 source digest 和既有 tag；既有 tag 指向同一 digest 时继续，指向其他 digest 时立即失败。只有最终
-release-set artifact 和 provenance 都生成后，才能宣布该 deployment family 可部署。
