We consider Khovanov complexes as a local system on the space of knots. We extend it to the singular locus and introduce the definition of a local system of finite type n. We show that Khovanov theory decomposes into a "Taylor series" over theories of finite type. We also discuss a 3-dimensional generalization of our construction.
