Partial-drain test transactions
Save (formerly Solend)'s assessment for RD-F-091 — scored gray on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
Partial-drain test transactions: pre-strike small-value drain pattern. Applicable to Solana (on-chain detectable). T-09 phase-2 signal. No public reports of test-transaction patterns against Save/Solend contracts in trailing 90 days. The Nov 2022 oracle attack had a two-phase structure (probe attempt at 12:15 AM, exploit at 2:16 AM same night) that partially matches this pattern, but that is historical context, not a current signal state.

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).
