 - D-305/ADR-0393（已接受）：Plugin Package Manifest 的逻辑 Secret requirement 获得按 resource generation 固定的不可变 binding。binding 精确覆盖 Manifest requirements，只保存同 Project、显式 version 的 `qlsecret://` 引用与 `approved-action-execution|local-owner-confirmation` authority evidence digest，不保存 Secret 明文；required 不可为空，optional 可显式为 `null`。发布由当前 active installation head、lock、generation 与 Manifest digest 联合 fencing，相同事实幂等、不同事实冲突；domain-separated digest、最多 64 项和 64 KiB 单行预算同时约束 Local 与 Cluster。SQLite 追加 `0091` ledger 与 capability v46，PostgreSQL 追加 `pg-0059`、capability v58，并只向 package executor 授予 `SELECT, INSERT`。不新增 package、daemon、timer、watcher、连接、缓存或集群 workload，低配路由设备只承担一个有界表和三个索引。D-305 不冒充 Secret 已进入执行路径：现有 materialization 拒绝仍保留，D-306 再完成用户授权、Secret resolution、runtime consumption 与 lifecycle/rebinding 语义。core 509/509、SQLite 232/232、PostgreSQL 316 pass/1 条件 skip；完整 18-package clean build/test 退出 0，backend 1,188 pass/2 skip，五项边界审计零 finding，workspace 仍无 single-source/shallow-source package。PostgreSQL 18.4 arm64 HA 125 项 gate 全绿、timeline `1→2`，报告 SHA-256 为 `acf0fea7ca7699989dfe70f5dd0061cdf5fb1968c691094331fea06ce01b96dc`。
 - D-306A/ADR-0394（已接受）：Package Task source 以 `package-secret` placeholder 引用逻辑 requirement，materialization 只用当前 generation 的 D-305 binding 编译为已有、固定 version 的 Task `SecretRef`；Package source 直接携带 SecretRef、缺失 binding、未批准 `secret.use`、跨 binding 引用和 optional/required 漂移全部失败关闭。binding 快照不含明文并进入 materialized revision digest，Local/Cluster 启动发布复用既有 repository/pool，Task dispatch、Local 短时解密和 Cluster offer/lease-fenced delivery 不另造协议。SQLite/PostgreSQL INSERT trigger 同时防止直接写库绕过；Local 只读 readiness 继续不加载 DDL。Local contract v47、Cluster v59；不新增 package、表、索引、连接、daemon、watcher、timer、cache 或 workload。完整 18-package clean build/test 退出 0；backend 1,188 pass/2 条件 skip/0 fail；五项 package/dependency/edge/service-manager/local-image 审计零 finding，workspace 仍无 single-source/shallow-source package，两个有序 migration ledger 精确为 PostgreSQL 61、SQLite 95 个 source；PostgreSQL 18.4 arm64 HA 125 项 gate 全绿、timeline `1→2`，报告 SHA-256 为 `f9107e8e54892a788779758f0573ac8d6a80f6d086516a1f5f5bbacb59bbb4be`。D-306A 不冒充产品闭环：Local bind/rebind 命令、Cluster Approved Action/API 与新 generation rotation/revocation 编排属于 D-306B。

-- 已冻结共享 transition plan v1 的 lineage 与差异分类语义；Local/Cluster activation 前发布和持久化门仍待实现，因此 ADR 保持 Proposed。
+- 已冻结共享 transition plan v1 的 lineage 与差异分类语义，并完成 Local/Cluster 的 activation 前持久化门：SQLite capability v48 通过 migration 0095/0096、PostgreSQL capability v61 通过 migration pg0062，把 repository 写入和数据库 trigger 同时约束为“当前 active target”或“由完整上一 active lineage 支撑、且为 durable install history 最大 generation 的 staged target”。`queued|activating|failed`、陈旧/跳代 staged target、断裂 lineage 与直接 SQL 绕过均失败关闭；readiness 校验 exact trigger/function attachment，避免 schema 名义升级但约束缺失。
+- 本切片没有新增 workspace package、第三方依赖、表、连接、daemon、timer、watcher 或常驻资源；Edge/Standalone 只增加 SQLite schema guard，Cluster 复用既有 PostgreSQL Pool/role。完整 18-package 串行测试与 backend 门已通过；真实 PostgreSQL 18.4 的 migration/runtime role 门证明 active、合规 staged 与 exact replay 可写，activating、陈旧/非最大 staged 以及直接 SQL 可被拒绝。
+- Local Owner 与 Cluster management/executor 尚未消费 transition plan，完成“审批 → 发布 binding → materialize → active CAS”的产品纵切面；真实 Kubernetes rotation/revoke、升级失败回滚及物理低配设备证据也仍待完成。因此 ADR 继续保持 Proposed，下一切片只补产品编排，不再扩张 package 或常驻部署面。
