+## [Unreleased]
+
+## [0.1.4] - 2026-10-05
+
+### Fixed
+
+- **Delegated mounts fail closed without an allowlist.** `evaluateRuntimeAction` now denies a delegated action when the mounted permission proof has an empty or missing `allowedActions` list, and `buildRuntimeBundle` preserves a present-but-empty list instead of dropping it. Controller-owned mounts (no delegation) keep their existing behavior.
+
+### Upgrade

+npm install @proofable/sdk@0.1.4
