// Package llm — context-overflow classification for adaptive retry.
//
// When a request's prompt exceeds the model's context window, every
// provider fails it — but each phrases the error differently (the
// HTTP providers relay their API's wording, the local llama.cpp
// provider its own, the CLI providers whatever their binary printed).
// IsContextOverflow recognises that failure mode across all of them so
// the assist layer can react to it (see the svc package's adaptive
// chunk-bisection retry) instead of surfacing a hard error.
