   - Kafka client、direct publish、refresh replay、projector 和 live SSE consumer group。
 - production 与 development 共享同一个 HWLAB Gitea PaC Repository CR；两个 lane 使用独立 consumer，并由 consumer params 覆盖 source branch、snapshot、Pipeline 和 runtime identity。
 - 共享 Repository 避免同一镜像仓库重复声明 PaC Repository；独立 consumer 仍保持 production 自动交付路径与 development 完全隔离。
+- `lanes.production.targets.NC01.sourceAuthority.giteaMirrorRepoKey` 已统一为共享 authority `hwlab-nc01-v03`，不再引用不存在的 production repo key。
+- delivery authority parser 以 consumer params 解析 branch 与 snapshot：
+  - 显式 consumer override 优先；
+  - 未显式覆盖时继承 Repository 默认；
+  - 多分支镜像优先匹配同 branch authority；
+  - 唯一共享镜像允许 production consumer 复用同一 Repository。
 - 通用 HWLAB lane parser 和 plan 已投影 migration ledger，并从 owning YAML 动态生成合法 lane 提示。
 - `config/platform-infra/kafka.yaml` 已声明 production Cloud API Kafka ACL，未改变 topic、实时和回放架构。
