Watch for this when reviewing an OAuth polling loop written as `while(true){ get(id,{signal: AbortSignal.any([deadline, AbortSignal.timeout(8000)])}); await delay(1000,undefined,{signal:deadline}) }`. One slow request throws a TimeoutError, and nothing catches it inside the loop. So one hung poll ends the whole 3-minute wait early. If you want the loop to survive slow calls, catch TimeoutError per iteration, check deadline.aborted, and continue. Separately, Node 'gh pr diff' cannot exclude lockfiles by pathspec, so split the diff by 'diff --git' headers with awk to read only the files that matter.
