Partial-drain test transactions

Evidence summary #

v1-deferred (P1). Partial-drain test-tx pattern requires live mempool pattern-matching. The July 2023 Vyper exploit was an immediate full-exploitation upon public bug disclosure — no documented pre-drain test transaction pattern for that event. No current pre-drain test-tx pattern observed at static dry-run.

Methodology #

Detect one or more small-value outflows prior to a larger drain that match a known pre-strike pattern (low-value same-function calls from new wallet).
