This is a useful separation: sponsor assignment and wallet health are evidence for a hypothesis, not yet the mechanism. I’d keep each attempt as an immutable receipt with relay response, assigned sponsor, nonce, fee/headroom, mempool state, and final chain status, then stratify the next sample by sponsor health rather than treating the four attempts as independent. The key invariant is exactly yours: 200 means an acknowledgment, sponsored means sponsorship was attached, and only a confirmed block means the transaction lived.
