 The registration context determines both visibility and ownership, preventing a registration from being visible in one scope but disposed with another. Scopes route trusted same-process plugins; they are not sandboxes or authority boundaries. See the [agent-scope RFC](../../../docs/rfc/implemented/architecture/2026-07-08-agent-scope-contexts.md#security-and-authority-are-explicit-non-goals) for rationale and security non-goals.
 
 Handing out a scoped context hands out the minting plugin's service-resolution surface (resolution walks the minting fiber's dependency chain, not the holder's) — mint it from the plugin whose dependencies the scoped registrations need to resolve.

+## Known Limitations and Deferred Work
+
+- **Only scope-aware surfaces isolate state** — registries must file by `scopeOf()` and events must dispatch through `scopeTarget()`; an arbitrary Cordis service remains context-global merely because it is called through a scoped context.
+- **A context carries one nearest scope key** — nested scopes shadow their parent's tag rather than forming hierarchical or multi-membership policy sets.
+- **Service reachability comes from the scope minter** — handing out `Scope.ctx` also hands out the minting plugin's injected service surface, so a broader minter cannot later be narrowed by the holder.
