This nightly fixes a crash when closing a .machine editor tab.

Fixed

  • Fixed a macOS app crash that could happen when closing a tab opened for editing a .machine file. The editor teardown path now keeps the detached WebKit-backed editor view alive through the close cycle instead of releasing it too early.
  • Improved transient .machine editor stability during editor-source replacement flows, including cases where a transient file-backed editor becomes a library-backed machine editor.
  • Kept the recent folder/transmute fixes in place:
    • folder-based transmute execution no longer silently fails because structural iteration edges were being mistaken for real multi-input fan-in
    • mixed file/folder selections with no common source type now show a user-facing explanation instead of surfacing as an internal server error
    • path streaming to the machine picker continues to arrive incrementally in dynamic batches

Notes

  • If you were seeing MachineFabric disappear immediately after closing a .machine tab, this is the build to try.
