How code 19 preserves the quran?

We hear these days that the code preserves Quran....Though there is not a single sentence in the fully detailed quran about some mathematical system or code 19 preserving, protecting and prooving Quran, believers of the code doctrine proudly boast with phrases(i am paraphrasing): the code preserves quran, the code protecs quran, the code prooves Quran etc But how, actually, it preserves and protects the Quran gentlemans?

Does it really protects or its just a wishfull thinking and empty boasting?

The code actually prooves the corruption of the Quran... The fact is that almost there is no a single feature- word, initials,etc.counted,calculated,used- without being some exces in the words or leters or without some cheathing in the method or without being exception(inclusion and exclusion etc)this and that-for which the followers of the code say "disregard it while counting" or "we should count this way and not that way" or "we should "exclude" it from counting" (from this reason or that) etc.etc.etc. The most glaring example for this are counts of bismillah`s words and counts of initials... Even after the deletion of 9/128-129(!)-the fact is that NOT A SINGLE count of bismillah`s word is 19 divisible...19 divisible counts are product of manipulations with counts -the counts are actually doctored-false... Also, counts of initials...There are many errors in khalifas counts and methods of analysis and this is admited by other researchers- proponents and opponents. Rashad himself changed his counts during years many times and according his freind Edip Yuksel( a proponent of the code) Rashad was also aware of these errors after they were indicated by critics and they intended to make a new research to resolve the problems but early death stopped him. Having this in mind and analysing counts of initials in a consistent way, the fact is that no matter how counts of initials are analysed we get nothing...in the best cases we get only a few 19 divisible hits. An objective statistical analysis shows only normal statistical variations of 19 divisibility- that is-inside the low of the probability. That is, in regards of 19 divisibility, the counts of initials are nothing special, nothing significant and not to speak about divinity or miraculousness of these counts! "The code",that is,the datas presented and considered as the code actually proves that there is no code embeded in Quran OR that the Quran is totally changed and corrupted and full of false insertions even after corrections made by Rashad. I only wonder what next will be deleted under the disguise of the divine preservation of the Quran. Besides that all, how it happened that so important doctrine -code 19- which have so important and crutial functions preserving, prooving, protecting,purifying of the Quran etc is not mentioned at all in fuly detailed Quran? Allah mentions in the quran diferent sort of details in regerds of all things, it detaily describes the signs of moses which occured in the past, but it forgots to list such important functions of no 19 preserving , protecting, prooving etc. It even does not say that 19 is a sign??!! So accordingly, if the code is the truth then it only further prooves the corruption of the quran - the verses that proves and supports the code must have been be deleted as well?
