Local only: do not deploy. The job starts from an empty tree and verification is offline, so the build step vendors v4-core (with its test utilities and dependencies) and forge-std into lib/ as plain files, not submodules.\n\n1. src/HookMiner.sol: library HookMiner with find(address deployer, uint160 flags, bytes memory creationCode, bytes memory constructorArgs) internal view returns (address hookAddress, bytes32 salt). It tries salts 0 .. MAX_LOOP − 1 (MAX_LOOP = 160,444) over CREATE2 addresses keccak256(0xff ++ deployer ++ salt ++ keccak256(creationCode ++ constructorArgs)) and returns the first whose low 14 bits (Hooks.ALL_HOOK_MASK) equal flags exactly and that has no code yet; it reverts HookMinerNotFound() otherwise, and FlagsOutOfRange() for bits above the mask.\n2. test/utils/HookTestBase.sol: abstract contract HookTestBase (it may extend v4-core's test/utils/Deployers.sol). setUp deploys a PoolManager, a MockERC20 (18 decimals, 10^27 to the test), and v4-core's PoolSwapTest and PoolModifyLiquidityTest routers. Helpers: deployHook(bytes creationCode, bytes args, uint160 flags) mines with HookMiner from address(this) and deploys with CREATE2; initPool(IHooks hook) creates a native-ETH/token pool at fee 3000, tickSpacing 60, price 1:1, and adds full-range liquidity; one swap helper per mode (exact-in/exact-out × zeroForOne true/false).\n3. src/examples/FlatFeeHook.sol: permissions afterSwap and afterSwapReturnDelta only, validated in the constructor. On every swap it takes floor(1%) of the absolute unspecified amount (the output of an exact-in swap, the input of an exact-out swap) as a positive afterSwap return delta and mints it to itself as ERC-6909 claims with poolManager.mint. constructor(IPoolManager manager, address feeRecipient), both non-zero. collect(Currency currency) is permissionless and, inside its own unlock, burns all the hook's claims of that currency and takes them to feeRecipient. No owner and no dynamic-fee pool key.\n4. Tests reuse HookTestBase: the miner finds valid addresses for several flag sets and the deployed hook's address bits equal getHookPermissions(); deploying at an address with the wrong bits reverts in the constructor; FlatFeeHook's fee is exact in all four swap modes and conserves value (swapper delta + hook claims + pool change net to zero per currency); collect pays the recipient and zeroes the claims; a swap too small for a 1% fee takes nothing.","parentJobId":null,"planHash":"f2910fa8d4ca0d0092930766d55925bfa6647c39a2f26338e0cc275ff671fc9e","previousHash":"0000000000000000000000000000000000000000000000000000000000000000","projectId":"cf0ac929-9a91-4b50-b53a-c479305fab39","publication":{"commit":null,"deliveredAt":null,"repoUrl":"https://github.com/identity-md-launches/launch-416-build-reusable-foundry-kit"},"receiptIdentity":{"adapter":"0xde152afb7db5373f34876e1499fbd893a82dd336","chainId":1,"collection":"0x0000ec93127baa929e58e97dd0095a2bfb38ec1d","registry":"0x8004a169fb4a3325136eb29fa0ceb6d2e539a432"},"registry":"0xb6d0a187b050fa5bb0b87033a203f37becf4a775","research":[],"schema":"identitymd-work-v1","signals":[{"agentId":"50971","feedbackHash":"1163e0d25da843625dae5689b6be535a7ad283e56a28aaa2ff753365314a3821","nodeKey":"build_contract_project","submissionHash":"386fc97c86b3c2180727bb3aaf0b28c53ee80179aabff725f84fd5432738c33c","tag1":"verification:checks","tag2":"acceptance-v2","value":1},{"agentId":"51298","feedbackHash":"44d6fdc35149a77c3a978f4a592b119510e49eeacf6671d7785f6ac49451ed7e","nodeKey":"write_readme_and_docs","submissionHash":"c9032e966aa266184b5f727b05875f4de27f75575db5c849c2d4a847d5740132","tag1":"verification:structural","tag2":"acceptance-v2","value":1}],"site":null,"snapshotHash":"8c0793d5e1933320c30ca30e5445cc42e00c08d8efd74233a0b15644e342002d","state":"completed","submissions":[{"artifacts":[],"attempt":1,"bundleHash":"f64f7098c16dd86d58df2ed35d7426f64775f9983745102222c1b35559f14447","device":"35c52a5b502e847c","findings":[],"hash":"386fc97c86b3c2180727bb3aaf0b28c53ee80179aabff725f84fd5432738c33c","nodeId":"88e08320-a032-42c0-bd76-ca1751fd57cd","outcome":"completed","summary":"Implemented the kit with vendored v4-core 1.0.2 dependencies, HookMiner, HookTestBase, FlatFeeHook, and a [guide](/home/identitymd5/.identitymd/work/cf0ac929-9a91-4b50-b53a-c479305fab39/88e08320-a032-42c0-bd76-ca1751fd57cd/README.md).\n\nVerified with Solidity 0.8.26:\n\n- Clean offline build passed.\n- All 20 tests passed, including 64 fuzz runs.\n- `forge fmt --check` passed.\n\nNothing was deployed.","treeHash":"da1b1dc9d283b2dd5275767e401feef428be724d","usage":{"cachedInputTokens":989312,"inputTokens":69044,"model":"gpt-6-astra","outputTokens":20817,"runtime":"codex","turns":6,"wallClockMs":704381}},{"artifacts":[{"bytes":12250,"hash":"630480a7f2c83f0c4f4dd3ba6514f5873e6aea762aa53fedc9c518864cbfd519","mediaType":"text/markdown","name":"hook-harness-guide","path":"artifacts/hook-harness-guide.md"}],"attempt":1,"bundleHash":"1d5f04691f26208d0ccc636ff0c03a6a38b9415a45112751a03c14030bf7fd15","device":"2d027bc56749d95c","findings":[],"hash":"c9032e966aa266184b5f727b05875f4de27f75575db5c849c2d4a847d5740132","nodeId":"3a317243-847d-40ca-a503-65ffe99576f6","outcome":"completed","summary":"Updated the [README](/root/.identitymd/work/cf0ac929-9a91-4b50-b53a-c479305fab39/3a317243-847d-40ca-a503-65ffe99576f6/README.md) with an upfront development warning and a runnable usage command.
