Do the narrations of Hafs from Asim, through the طريق الشاطبية, differ from those through the طريق طيبة النشر in terms of vowels and letters, or is the difference limited to tajweed, and is the طريق الشاطبية more authentic than the طريق طيبة النشر?

"Tayyibat al-Nashr" included methods and additions to "al-Shatibiyyah" in both Usul (fundamental principles) and Farsh (word variants), and not solely in Tajweed (definition) (pronunciation rules). Examples include the recitation of the words {يَقْبِضُ وَيَبْسُطُ} (He withholds and extends), {بَصْطَةً} (an increase), {المصيطرون} (the controllers), and {بِمُصَيْطِرٍ} (a controller) with either seen (س) or saad (ص). While "al-Shatibiyyah" specifies the two instances in Surah (definition) Al-Baqarah and Al-A'raf with seen, and the instance in Al-Ghashiyah with saad, "Tayyibat al-Nashr" added the recitation of the two instances in Al-Baqarah and Al-A'raf with saad, and the instance in Al-Ghashiyah with seen. Additionally, "Tayyibat al-Nashr" added for Hafs the sakt (brief pause) on the silent letter before a hamza, the ghunnah (nasalization) on the letters lam and ra, the takbir (saying "Allahu Akbar"), the omission of the four specified saktat, and the differing opinions regarding the lengths of the mudud (prolongations). All these established methods are considered authentic and transmitted through continuous chains (mutawatir).
