Method resolveCompletionBufferSize

cel/program.go:491–501

resolveCompletionBufferSize returns the size of the async completion channel. When unset, it defaults to the effective launch concurrency so that all in-flight calls can report completion without blocking. An unbuffered channel would make a completed call hold its launch slot until the evaluator dra
