Release Farm (token symbol FARMX) on Sepolia as a univ4_hook launch. Token: Farm (FARMX), total supply 1,000,000,000 FARMX with 18 decimals, minted once to the deployer (a separate zero-argument ERC-20, no mint, owner or admin). Hook: LiquidityMiningHook, a Uniswap v4 hook on the token's native-ETH pool that streams a reward pool of the pool's currency1 (the launch token, for the launch pool) to staked liquidity pro rata to liquidity-seconds, Synthetix-style per pool: rewardPerLiquidity (scaled by 1e18) is updated before every stake change and claim. Staking: a position (the PoolManager's key: sender, tickLower, tickUpper, salt) is staked only when liquidity is added with a beneficiary in hookData (exactly 32 bytes, non-zero address). The first such add fixes the beneficiary for that key; later adds to the key count toward it with or without hookData; liquidity added before any beneficiary, including the factory's seed position, is never staked and never dilutes rewards. afterAddLiquidity (liquidityDelta > 0) adds liquidityDelta to staked[key] and totalStaked; afterRemoveLiquidity sets staked[key] = min(staked[key], the position's liquidity after the removal, read with StateLibrary), so fee collection (delta 0) changes nothing. Out-of-range liquidity earns like in-range liquidity: a disclosed simplification. Funding: anyone calls fund(poolKey, amount), which pulls currency1 with transferFrom (counting the balance change) and sets rate = (amount + unstreamed remainder + idle) / 30 days and periodEnd = now + 30 days. Stream time that passes while totalStaked is 0 accrues to idle, which the next fund() re-streams, so no tokens are stranded. claim(poolKey, positionKey), callable only by that key's beneficiary, pays its accrued tokens (CEI). The beneficiary never changes, even if a PositionManager NFT is transferred. ETH is never accepted. Events: Staked, Unstaked, Funded, Claimed. Views: earned(poolId, positionKey), rewardRate, periodEnd, staked, totalStaked, positionsOf(beneficiary). The symbol is FARMX, not FARM, which is an existing token's ticker. Deploy shape, matching the live Sepolia hook launches 170 and 186 (168 passed the mainnet PoolManager and is not a model): LiquidityMiningHook's only constructor argument is the Sepolia PoolManager 0xE03A1074c86CFeDd5C142C4F04F1a1536e203543; every rate, window and threshold here is a source constant; there is no owner, admin, setter, pause, upgrade or sweep, and no $owner or $token argument. Permissions are exactly afterAddLiquidity, afterRemoveLiquidity (low address bits 0x0500), all others false; the constructor calls Hooks.validateHookPermissions and the CREATE2 salt is mined for those bits. The factory initializes the pool (currency0 native ETH, currency1 FARMX, fee 3000, tickSpacing 60) and seeds one-sided FARMX liquidity, so nothing in the hook may revert that initialize or that liquidity add (launch 138 was parked when a beforeInitialize gate reverted the factory), and the first buy lands in a pool that holds no ETH. All state is keyed by PoolId; a pool on this hook whose currency0 is not native ETH gets zero deltas and no other effect. Every callback requires msg.sender == PoolManager. Tests (Foundry, a real v4-core PoolManager deployed in the test, hook at a mined address): a launch rehearsal that initializes at the manifest price, seeds one-sided FARMX liquidity like the factory and makes the first buy into the ETH-less pool; exact-in and exact-out in both directions; dust amounts; a pool whose currency0 is not ETH; direct callback calls from a non-PoolManager address revert; fuzzed sizes; and specifically: two stakers entering at different times split rewards by liquidity-seconds; a fund while nothing is staked is fully re-streamed by the next fund; the factory-style seed position earns nothing; fee collection does not unstake; partial removal reduces the stake; claims sum to at most funded tokens and the hook's token balance always covers earned plus unstreamed plus idle. An independent adversarial review (read-only) must attack: accumulator ordering (update before every stake change), removal paths through PositionManager (decrease, burn, delta 0), idle and rounding leakage, beneficiary hijack on shared keys, fee-on-transfer funding, and precision or overflow in rewardPerLiquidity. It reports each finding with the exact call sequence that triggers it. Website: one static page (dist/index.html) that reads the hook's views and events and pool and position state through Uniswap's Sepolia StateView, and sends every liquidity action through Uniswap's published Sepolia PositionManager (check it has code; never the unguarded PoolModifyLiquidityTest, whose positions anyone can remove). It shows the stream (rate, period end, total staked), a fund form (approve plus fund), the connected wallet's positions with earned rewards and claim buttons, and a PositionManager mint form for full-range positions only (ticks -887220 to 887220; token approval through Permit2, as the v4 SDK does) that puts the wallet in hookData; nothing else. Farm is a Sepolia test toy: its token and any pot have no value, and nothing here promises a return.

Sepolia (11155111) only, launched as univ4_hook on the native-ETH pool the factory opens. GitHub publication and IPFS hosting are approved. Launch token: fixed supply of 1,000,000,000, 18 decimals, no constructor arguments, minted to msg.sender, no mint or admin. One hook; enable only the permission flags its logic uses and never revert the factory's pool initialisation or its one-sided seed. Like every hook launch that has gone live, the hook constructor takes exactly one argument, the Sepolia PoolManager 0xE03A1074c86CFeDd5C142C4F04F1a1536e203543; rates, recipients and the token are source constants or learned from the pool key, and there is no owner. Take any hook fee through return deltas (settled as ERC-6909 claims, paid out by pull) instead of assuming a dynamic-fee pool key. Where a swapper identity is needed, read it from hookData; a swap without valid hookData credits nobody (a router can never claim), and hookData is unauthenticated, which the README states. No external oracles or VRF, no proxies, delegatecall or selfdestruct. foundry.toml sets bytecode_hash = "none". Any website is a static export with index.html in dist/. Site label lab-liquidity-mining-hook.

Build FARMX and LiquidityMiningHook (permissions afterAddLiquidity, afterRemoveLiquidity; PoolManager-only constructor) with a launch-rehearsal Foundry suite and an independent adversarial review, deploy them through the factory on Sepolia, then build the one-page site against the live pool.
