The final acceptance token appears only after code, correction, phase, and rounds agree. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.
highlighted = computed this step
The phase bridge source is part of the audit
The phase source restores mapped word 111, and the round source gives correction index 1.
mfixed=111c=1
All cited fields agree in the accepted audit
The accepted audit has syndrome 11, correction index 1, and fixed word 111. The accepted bit is 1.
