A permanently rejected member reenters the retry set

Member previewVariant 3 · 3 implementations · 6 checks per implementation

Case contract

open(list of item IDs) establishes ordered batch. result(id,status,value) records first success, retryable failure, or permanent failure; unknown IDs ignored. retry returns unresolved/retryable items in original order including duplicates. done returns values or null in original positions. Success/permanent terminal entries cannot be overwritten by late responses.

Why this case matters

Offline deterministic model of HTTP request retries.

One recorded failure

Sample boundary fixture
