Narrated Ibn `Abbas:The Prophet (ﷺ) fixed Dhul-Hulaifa as the Miqat for the people of Medina, Al-Juhfa for the people of Sham, Qarn-al-Manazil for the people of Najd, and Yalamlam for the people of Yemen; and these Mawaqit are for those living at those very places, and besides them for those whom come through them with the intention of performing Hajj and Umra; and whoever is living within these Mawaqit should assume Ihram from where he starts, and the people of Mecca can assume Ihram from Mecca

The label above is the grade most of these scholars gave — one dissenting opinion no longer speaks for all of them. If any scholar calls a narration fabricated, that verdict is shown instead, whatever the others say. Each scholar's own wording:
Every narration in Sahih al-Bukhari is accepted as Sahih (authentic) by the established status of the book.
