Errata
Page 414 in Pacific J Math paper (2011): "the zerocycle e is given by (ι,1)" should be corrected as "the zerocycle e is given by (ι,2)". Theorem 3.1 of this paper still holds, and an alternative proof can be found as Corollary 4.9 in Pacific J Math paper (2023). The original proof relies on Lemma 4.5 in AGT paper (2008) that seems to miss factor of 2.
Sorry for misspelling the name of Thistleswaite in JKTR paper (2021).
AGT paper (2008) and Pacific J Math paper (2011) contain sign errors;
the signs of 7th, 8th and 9th graphs in the nontrivalent graph cocycle should be replaced by respectively +,  and +.
These corrections do not cause any problems on the results of these papers since these graphs do not essentially contribute to the integrals. (3 June 2013)
