What's Changed
- Added exported OS 27 automation header support for Display and Stage Manager triggers.
- Added conservative catalog coverage for Mac External Drive, File Modified, and Folder Changed automation exports.
- Reject bare lossy Mac drive/file/folder trigger headers instead of presenting invalid picker-less automations as import-ready.
- Bumped Claude and Codex plugin manifests plus install docs to 1.2.1.
This is a compatibility/support release on top of 1.2.0. Existing macOS 26 users remain on the conservative default validation surface unless they explicitly target OS 27.
