Abstract
For , let be the annular closure of We prove that triply graded annular Khovanov homology over detects the underlying unoriented annular link . If , the only ambiguity is overall orientation reversal. If , the only ambiguity is independent reversal of components; every such reorientation has the same homology, so this is sharp. The proof combines braid detection from the extremal annular grading with a rigidity theorem: the Jones polynomial and exponent sum determine up to conjugacy in .
