Global Blockwise Morita Equivalences for the Spectral Langlands Category

This preprint proves unconditional global blockwise Morita equivalences for \ ( (₆ (X) ) \) in positive characteristic k= F_. For each spectral Bernstein block s and each depth stratum d, it establishes a fiberwise Morita equivalence between the heart of the restricted t-structure and the product of module categories over the finite-dimensional endomorphism algebras of the local Springer sheaves S_ᵏ. When the stratum has finitely many k-points, this product collapses to a single finite-dimensional algebra ₒ, ₃. The proof combines three unconditional inputs from earlier companion work — the spectral support package, the fiber algebra theorem for modular singular support, and the Springer projective-generator theorem — with two new ingredients developed here: the spectral Bernstein decomposition and spectral parabolic induction. The paper also proves Hecke intertwining, parabolic compatibility, and global gluing, and recovers both the characteristic-zero Arinkin–Gaitsgory theory and the depth-zero GLₙ local Langlands picture as special cases. The results are presented as the Morita-level abelian-categorical foundation for a later braided monoidal upgrade via the Springer Hopf diagonal and Schauenburg reconstruction.
