certain fuzzing strategies have mechanisms to detect if ebpf programs ran successfully or not (e.g set a dummy value to a map entry).
If the program does not write these control values we mark them as "flaky" or that for any reason they did not run successfully

Are there ways to tie back coverage to an input(s)?

not yet, I am actually working on a code change for something somewhat similar.
Actually the coverage information is available as part of every run program response: https://github.com/google/buzzer/blob/main/proto/ebpf_fuzzer.proto#L58
