+## Ownership
+- Module owner: Proxy Auth Access lane (`WT-05`).
+- Scope owner: Shared Modules team for proxy auth/access SDK boundary.
+
+## Purpose
+Define the additive v1 module boundary for proxy auth/access SDK contracts and interfaces before
+any breaking code migration.
+
+## Interfaces (Contract-First)
+- `AccessSDK` public interface with initialize/authorize/provider lookup operations.
+- `AuthProvider` interface with provider identity, credential validation, and authorization.
+- Registry behavior is defined by `docs/contracts/proxy-auth-access-sdk.contract.json`.
+
+## Migration Boundaries
+- No runtime code moves in this step.
+- No fallback, shim, or compatibility behavior.
+- Existing call paths remain unchanged until a dedicated migration rollout.
+
+## Integration Notes
+- Downstream implementations must satisfy the registry and semver contract.
+- Contract changes require an explicit semver evaluation and contract version bump.
