Where the article explains it
Disconfirmed if mainstream RAG frameworks in 2028 still expose a single global and a single global k with no per-workload override as their primary configuration surface.
The passage around this formula
One. Hybrid weight and reranker candidate count will increasingly be treated as workload-specific values recorded and versioned alongside the index build, rather than global defaults set once at launch and left alone. Disconfirmed if mainstream RAG frameworks in 2028 still expose a single global and a single global k with no per-workload override as their primary configuration surface.
