Conversation

Archive relies on the checkpoint TTL to reclaim a checkpoint whose physical delete failed (the claim is already gone, so the ck is unpinned and only the TTL sweep can remove it). With
checkpoint_ttl_hours=0that rare orphan is never reclaimed — emit a startup warning so the misconfiguration is visible.One-line change in
