In this second installment of the Alpay Algebra framework, I formally define identity as a fixed point that emerges through categorical recursion. Building upon the transfinite operator φ^∞, I characterize identity as the universal solution to a self-referential functorial equation over a small cartesian closed category. I prove the existence and uniqueness of such identity-fixed-points via ordinal-indexed iteration, and interpret their convergence through internal categorical limits. Functors, adjunctions, and morphisms are reconstructed as dynamic traces of evolving states governed by φ, reframing identity not as a static label but as a stabilized process. Through formal theorems and symbolic flows, I show how these fixed points encode symbolic memory, recursive coherence, and semantic invariance. This paper positions identity as a mathematical structure that arises from within the logic of change itself computable, convergent, and categorically intrinsic.
