If a mechanism existed that would allow Texas to leave the Union it would have been included just like it included the possibility of a pendactic (fancy Greek word for 5 way split) break up within the Union.

did you bother to actually READ the Constitution ( including the 9th & 10th Amendments to the BOR), instead of trying to think of an argument to try to avoid admitting that you are seriously in error???

but to answer your question, the RIGHT of secession was understood by educated people in 1845;nobody at that time needed any further explanation as to what the Constitution said/meant. (it is the STATISTS of 2009 that need to reevaluate their heresy/FOOLishness in reading the BOR.)

...or, if it was clearly understood at the time that ratification of the Constitution abrogated the perpetual nature of the Articles of Confederation, there would have been some contemporary written documentation for that abrogation.
