If there were truly “selective sweeps,” then those cases also don’t map cleanly to the Mk3 flaw. The randomness bug doesn’t give an attacker partial access. it gives them the full seed. Once the seed is weak, every UTXO derived from it is equally exposed.
Selective movement means something else was different between those UTXOs: a separate backup path, a reused seed, a partially‑exposed key, or an external leak. The Mk3 flaw is deterministic. Selective behavior isn’t.
