+# RAIL-FAB-WP-0006 - Multi-Repo Registry Onboarding
+
+## Goal
+
+Make the registry useful with real ecosystem data by registering available
+Railiance repositories, feeding their graph snapshots and library inventory, and
+documenting the operating loop agents should use before inspecting the combined
+model.
+
+## Tasks
+
+### T01 - Onboarding Manifest
+
+```task
+id: RAIL-FAB-WP-0006-T01
+status: todo
+priority: high
+state_hub_task_id: "4a17b588-daa2-4b79-b17a-b5806d96a111"
+```
+
+Define the repo onboarding manifest and expected local path, remote, graph,
+artifact, and SBOM inputs for registry sync.
+
+### T02 - Multi-Repo Sync Command
+
+```task
+id: RAIL-FAB-WP-0006-T02
+status: todo
+priority: high
+state_hub_task_id: "d993b52a-d253-4869-9de5-a7e1f1b268ce"
+```
+
+Add a local command that can register and sync multiple available Railiance
+repositories into the registry service.
+
+### T03 - Verification And Operating Notes
+
+```task
+id: RAIL-FAB-WP-0006-T03
+status: todo
+priority: medium
+state_hub_task_id: "e256b295-eacd-4321-b386-a08c143cdc77"
+```
+
+Verify the multi-repo registry loop and document how agents should run it before
+inspecting the ecosystem model.
