Extract the unchanged canonical plan model for typed Runtime snapshots without a Server dependency cycle. Bind Tool consumer identities to persisted Session/call IDs, use the owner-issued context and current publication authorization, and register through FeatureInstallPlan with cooperative shutdown.
Validation so far: root cargo check --locked, portable model 6 tests/doctest, Worker actual Component adapter 7 focused tests, Server plan 9 tests via shared isolation. Full product launch owner/pin lifecycle and Remote/Embedded vertical integration remain a subsequent coherent change.
