+**Fixed**
+
+* **Infinite recursion on image upload** — `wp_update_post()` (called to update the attachment GUID after S3 upload) was firing the `edit_attachment` WordPress action, which re-triggered the upload method, which called `wp_update_post()` again, creating infinite recursion. Xdebug killed the process at 512 stack frames, WordPress reported "The server cannot process the image". Fixed by: (1) removing the `edit_attachment` hook — `wp_update_attachment_metadata` covers all new-upload scenarios; (2) adding a static re-entry guard (`$in_progress` per attachment ID) as a safety net.
+
+* **Fatal error: fclose() on already-closed stream** — The AWS SDK (via Guzzle) closes file streams automatically after reading them for upload. The `finally` block was attempting to `fclose()` streams that were already closed, throwing `TypeError: fclose(): Argument #1 ($stream) must be an open stream resource`. Fixed by checking `is_resource($fh)` before calling `fclose()`.
