 ## [Unreleased]

 ### Changed (upstream PR #554 sync)
 - **BREAKING**: `:on-permission-request` is now **required** when calling `create-session`, `resume-session`, `<create-session`, and `<resume-session`. Calls without a handler throw `ExceptionInfo` with a descriptive message. This matches upstream Node.js SDK where `onPermissionRequest` is required in `SessionConfig` and `ResumeSessionConfig` (upstream PR #554).
 - `create-session` and `<create-session` no longer accept a 0-arity (no config) form — a config map with `:on-permission-request` must always be provided.
