Tests cover both parities and the fee bounds. Deliver a pinned/vendored Foundry project: the hook contract under src/, a Foundry test suite under test/ that exercises it against a real PoolManager from vendored v4-core (initialize a pool, add liquidity, run swaps through a router or PoolSwapTest), and a README. Validate the pool at afterInitialize where the design needs a dynamic fee (the pool must carry LPFeeLibrary.DYNAMIC_FEE_FLAG) and revert otherwise. Authenticate every callback as coming from the canonical PoolManager and never trust sender or hookData for identity. Keep per-PoolId state isolated, keep LP exits possible, and add no owner or admin powers beyond what the design names. No token, no deployment, no launch manifest, no website: this is source and tests for GitHub publication only.","parentJobId":null,"planHash":"3b060a37b144d8fc821e7c14a2fd6277d1eb1c4e94be9140a2ed2799f96e8c30","previousHash":"0000000000000000000000000000000000000000000000000000000000000000","projectId":"ca470b98-5e99-4771-8b9b-da4c01310a18","publication":{"commit":null,"deliveredAt":null,"repoUrl":"https://github.com/Identity-md/launch-76-build-blockparityfeehook-simple-creative"},"receiptIdentity":{"adapter":"0xde152afb7db5373f34876e1499fbd893a82dd336","chainId":1,"collection":"0x0000ec93127baa929e58e97dd0095a2bfb38ec1d","registry":"0x8004a169fb4a3325136eb29fa0ceb6d2e539a432"},"registry":"0xb6d0a187b050fa5bb0b87033a203f37becf4a775","research":[],"schema":"identitymd-work-v1","signals":[{"agentId":"50992","feedbackHash":"55a440b7972d27a48e8c6fa632be4280d69e27da056a08a24009233c670b60bc","nodeKey":"adversarial_review","submissionHash":"eca2cc8fc7eb1319ced76ebba2196bc2daac19d45dadceabc1c8e1e537ebb087","tag1":"review:submission","tag2":"acceptance-v2","value":1},{"agentId":"50906","feedbackHash":"2158225ac48e5a2a6fce4cae841c3f411e28acf2126c58bce66ed7de96ea1cfb","nodeKey":"build_contract_project","submissionHash":"89018d3681a3afb19c50f08de002f8be656791341c72568147c416b6bf3b2c19","tag1":"verification:checks","tag2":"acceptance-v2","value":1}],"site":null,"snapshotHash":"31fcfc593be61f9db73567d7e650b8e7a0ee9ecd5ab2c43ff361f33b1b39a72c","state":"completed","submissions":[{"artifacts":[],"attempt":1,"bundleHash":"992f6dc0303a0e10fe7cd08dd8f999eabb5227af9413a2e9792f97ae1bf854f6","device":"90f1f5c3374333a0","findings":[],"hash":"89018d3681a3afb19c50f08de002f8be656791341c72568147c416b6bf3b2c19","nodeId":"8b51de64-838b-46f6-88d4-5783ba75763c","outcome":"completed","summary":"Implemented the hook, pinned vendored dependencies, real PoolManager integration tests, and README.\n\nThe hook authenticates callbacks, requires dynamic-fee pools, applies immutable parity fees, and leaves LP exits unrestricted.\n\nValidation passed:\n\n- `forge build --offline`\n- `forge test --offline` — 12 tests passed\n- `forge fmt --check`\n\nREADME documents parameters, assumptions, responsibilities, and the 100% fee limitation.","treeHash":"f41da7b7de98d36851a54f3b74c023706eef6758","usage":{"cachedInputTokens":549504,"inputTokens":37337,"model":null,"outputTokens":8593,"runtime":"codex","turns":5,"wallClockMs":315442}},{"artifacts":[],"attempt":1,"bundleHash":null,"device":"62761ac059990ff7","findings":[{"description":"Fee parity is read from block.number.

The findings are in `.imd-findings.json`. I ran `forge test --offline` and all 12 tests passed.\n\nThe code checks out against the requested design:\n- **Caller checks:** `afterInitialize`, `beforeSwap` and the fallback all reject any caller other than the PoolManager.\n- **Permissions:** the address flags (`0x1080`) match `getHookPermissions`, with only `afterInitialize` and `beforeSwap` enabled.\n- **Dynamic fee:** `afterInitialize` requires the fee to equal `DYNAMIC_FEE_FLAG` exactly.\n- **Swap fee:** `beforeSwap` returns a zero delta and an override fee taken from `block.number` alone.\n- **Isolation and exits:** the hook keeps no state, so pools stay isolated, and it never gates liquidity removal.\n- **Admin powers:** there is no owner or admin role.\n- **Tests:** they run against a real PoolManager and check the emitted `Swap` fee on both parities.\n\nFindings, ranked by severity:\n1. **Low:** on chains like Arbitrum, `block.number` is an approximate L1 block number, so many L2 blocks share one parity. The README doesn't say this.\n2. **Low:** `test_WrongAddressFlagsRejected` uses a bare `expectRevert()`. It passes on any revert, so it doesn't prove the address-flag check fires.\n3. **Info:** `oddFee = 1_000_000` is allowed. An exact-input odd-block swap then returns zero output, and exact-output reverts. This is documented and tested, so it is not a defect.\n4. **Info:** a summary entry recording that no high or medium defects were found.\n\nI changed no files other than writing the findings file.","treeHash":null,"usage":{"cachedInputTokens":215700,"inputTokens":12,"model":"claude-sonnet-5","outputTokens":2977,"runtime":"claude","turns":6,"wallClockMs":40463}}],"verification":[{"checks":[{"durationMs":1860,"exitCode":0,"name":"build","output":"Compiling 74 files with Solc 0.8.26\nSolc 0.8.26 finished in 1.77s\nCompiler run successful!\n","passed":true},{"durationMs":202,"exitCode":0,"name":"test","output":"No files changed, compilation skipped\n\nRan 12 tests for test/BlockParityFeeHook.t.sol:BlockParityFeeHookTest\n[PASS] testFuzz_CallbackAuthentication(address) (runs: 256, μ: 27501, ~: 27501)\n[PASS] testFuzz_InvalidFeeBounds(uint24,uint24) (runs: 256, μ: 39441, ~: 39435)\n[PASS] testFuzz_ParityIgnoresSenderAndData(uint64,address,bytes) (runs: 256, μ: 20808, ~: 20811)\n[PASS] testFuzz_RealSwapsBothParitiesDirectionsAndModes(bool,bool) (runs: 256, μ: 301310, ~: 296448)\n[PASS] test_BoundaryFeesInRealPoolAndExit() (gas: 65787068)\n[PASS] test_InclusiveFeeBoundsAndEqualFees() (gas: 167134295)\n[PASS] test_PermissionsAndImmutableConfiguration() (gas: 20081)\n[PASS] test_RuntimeHasNoEscapeHatches() (gas: 646438)\n[PASS] test_StaticPoolInitializationRevertsAtomically() (gas: 61350)\n[PASS] test_TwoPoolsStayIndependentAndLPsExit() (gas: 653714)\n[PASS] test_WrongAddressFlagsRejected() (gas: 39391)\n[PASS] test_ZeroManagerRejected() (gas: 36496)\nSuite result: ok. 12 passed; 0 failed; 0 skipped; finished in 94.38ms (265.26ms CPU time)\n\nRan 1 test suite in 95.17ms (94.38ms CPU time): 12 tests passed, 0 failed, 0 skipped (12 total tests)\n","passed":true}],"detail":"all checks passed","evaluation":"checks","profile":"foundry","status":"accepted","submissionHash":"89018d3681a3afb19c50f08de002f8be656791341c72568147c416b6bf3b2c19","verifiedTreeHash":"f41da7b7de98d36851a54f3b74c023706eef6758","verifierVersion":"0.1.0+eab70f1b"}]}
