Such data are in one-to-one correspondence with an infinite set of defect correlation functions. We identify algebras and traces for known boundary conditions. Ward identities expressing the (twisted) periodicity of the trace highly constrain its structure, in many cases allowing for the complete solution. Our main examples in this paper are: the universal enveloping algebra   <math> <mi>U</mi> <mfenced> <mi>g</mi> </mfenced> </math>  $$ U\\left(\\mathfrak{g}\\right) $$  with the trace describing the Dirichlet boundary conditions; and the finite W-algebra   <math> <mi>W</mi> <mfenced> <mi>g</mi> <msub> <mi>t</mi> <mo>+</mo> </msub> </mfenced> </math>  $$ \\mathcal{W}\\left(\\mathfrak{g},{t}_{+}\\right) $$  with the trace describing the Nahm pole boundary conditions."
