Sota Check

One repeatable pass that stops fak from re-inventing known kernel art - before writing or optimizing a compute kernel (a quantized GEMM, a fused attention, a KV-cache reuse, a MoE dispatch, a Metal/CUDA kernel), it checks the SOTA prior-art matrix for the production reference (llama.cpp / Marlin / CUTLASS / FlashInfer / vLLM / SGLang / a named paper), decides the route (borrow / bind / stay-minimal), holds the result to the named oracle, and records what was consulted in a Prior-art trailer. Runs `fak sota <op|file>` to surface the reference, reads it, routes deliberately, and (when the matrix has a blind spot) adds the missing row so the next person inherits the map. The inward kernel-engineering counterpart of industry-score (the outward field map). Use before any kernel-optimization commit, when the PRIOR_ART advisory gate fires, when onboarding a new compute operation, or on a /loop cadence to keep the matrix honest against the tree.
