Isnads of al Nashr

Two types of sanads which Ibn al-Jazarī mentions in his book "Al-Nashr fī al-Qirāāt al-˘Ashr". The sanads of Ibn al-Jazarī which end by the author of a book (Secondary Turuq) are sanads of transmission i.e. he transmits the qirāāt (or knowledge) in the book via that sanad and did not necessarily recite the Qur'an according to what is found in that book whereas a sanad reaching to Rāwī ( such as - Hafs, Ibn Wardān , warsh...) is a sanad in which each link in the chain has read the entire Qur'an to the link above them. My Question is - Is the description I have given above correct & Is it forbidden to Partial recitation (Not a entire Quran recitation) and Ijazah of the rest of the Quran in Nashr.?Please give me a detailed answer.
