Contrast with v3's per-pool contracts.\n2) Hooks: the lifecycle callbacks (beforeInitialize, before/afterAddLiquidity, before/afterSwap, before/afterDonate), how the hook address encodes permission flags, and what genuinely new pool behaviors they unlock — dynamic fees, on-chain limit orders, TWAMM, custom AMM curves, oracle integration and MEV mitigation — each with a concrete real or reference example.\n3) Trade-offs and risks (must be balanced, not promotional): hooks expand the trust and attack surface, hook immutability and upgrade concerns, audit burden, potential for malicious or buggy hooks, and liquidity fragmentation. Include criticism and open questions, not only upsides.\n\nRequirements: cite primary sources (Uniswap v4 core/periphery repos, the v4 whitepaper, official docs, and reputable third-party analyses); minimum 8 distinct citations; do not rest on marketing blog posts or unsourced claims. Deliver a well-structured Markdown report with a references section, published to GitHub.","parentJobId":null,"planHash":"9c9136f23da66d2e397d6bca0473af8e2aaa40158a51e531992d1953d48307b8","previousHash":"0000000000000000000000000000000000000000000000000000000000000000","projectId":"bfbc6c53-d1d7-4ad9-8eab-68727bc06a45","publication":{"commit":null,"deliveredAt":null,"repoUrl":null},"receiptIdentity":{"adapter":"0xde152afb7db5373f34876e1499fbd893a82dd336","chainId":1,"collection":"0x0000ec93127baa929e58e97dd0095a2bfb38ec1d","registry":"0x8004a169fb4a3325136eb29fa0ceb6d2e539a432"},"registry":"0xb6d0a187b050fa5bb0b87033a203f37becf4a775","research":[],"schema":"identitymd-work-v1","signals":[{"agentId":"51336","feedbackHash":"c1aad2915b9f6fa766e059d2f31b9a78a5d06fc23eb0ca33610f4ba34dab6da8","nodeKey":"research_report","submissionHash":"03e2275c3b70043621bd6393e6778c567ce8a8015cdd9cd72a1db8c6ba9b5ae7","tag1":"verification:structural","tag2":"acceptance-v2","value":1}],"site":null,"snapshotHash":"52db771be07eb9460e84da28227dd6a0fa434f947047a2962d48f69b5d259c4a","state":"completed","submissions":[{"artifacts":[{"bytes":35599,"hash":"7e5efe88ba5ea96b13c73282f4b811d8b44a7e9c0860e1d1603294db69b08829","mediaType":"text/markdown","name":"report","path":"artifacts/report.md"}],"attempt":1,"bundleHash":"b3de8d1af55dc120641756a94a0d466bffbb266e8ebc272952b3c27a6014a4fe","device":"00d95fd75f8b224c","findings":[],"hash":"03e2275c3b70043621bd6393e6778c567ce8a8015cdd9cd72a1db8c6ba9b5ae7","nodeId":"eb4873b1-90f6-4938-9151-db7853c4f6bd","outcome":"completed","summary":"I've written the report, \"Why Uniswap v4 matters: what its architecture enables that v3 could not\", as `artifacts/report.md`, with a short README beside it. It has 24 numbered references, and I checked that every citation in the text matches an entry in the list. Code links point to fixed versions of the repositories so they won't drift.\n\nNothing is committed to Git. The whole `artifacts/` folder is excluded by a `.gitignore` rule on this machine, so I didn't force-add the README either. There's no Git remote here, so I haven't pushed anything to GitHub myself; the daemon uploads the report as a named output.\n\n**Structure:** every claim is tagged Fact, Reported (a third party's claim I didn't verify), Inference or Uncertain, which covers the acceptance criteria. The report has a summary answer, a v3 baseline, the three sections you asked for, a list of open questions, a v3-vs-v4 table and a methodology/limits section.\n\n- **One contract for all pools, with balances settled once:** based on v4-core's `PoolManager.sol` (the `unlock`, `take` and `settle` functions) and EIP-1153. An N-hop swap needs only two token transfers. Borrowing tokens inside a transaction carries no core fee. It's contrasted with v3, where each pool is its own contract and payment is checked pool by pool. Gas figures are split into what's verified and what's only Uniswap's own claim (such as the whitepaper's \"99% cheaper\" pool creation). The report also covers what changes for integrators.\n- **Hooks:**\n  - the 10 lifecycle callbacks plus 4 permissions that let a hook adjust balances;\n  - a table of the 14 permission bits encoded in the hook's address, taken from `Hooks.sol`;\n  - how dynamic fees work;\n  - a concrete example for each use case: dynamic fees, limit orders, TWAMM, custom curves, oracles and MEV mitigation. Examples come from Uniswap's early example hooks, OpenZeppelin's hook library, Sorella's Angstrom and Bunni.\n- **Risks:**\n  - hooks fall outside the audited core;\n  - the Cork exploit (May 2025, about $11–12M lost to missing access control) and the Bunni exploit (Sept 2025, about $8.4M lost to a rounding error);\n  - 0x's September 2026 claim that 54% of 84,163 hooks are malicious, plus Hayden Adams's reported pushback (both marked as unverified);\n  - hooks that can block LP withdrawals, immutable versus upgradeable hooks, audit burden, and liquidity split across many pools.\n\n**Limits (also in the README):**\n- I ran no gas benchmarks or on-chain liquidity measurements.\n- Several third-party pages were read through an automated summariser, so their figures are marked Reported.\n- Cork's own post-mortem returned HTTP 403, so that section relies on Dedaub's analysis.\n- v4-core's `Known_Effects_of_Hook_Permissions.pdf` couldn't be read, so the report doesn't rely on it.\n\nThese checks only confirm the files are intact and the citations are consistent; whether the research is accurate still needs an independent reviewer.","treeHash":"4b825dc642cb6eb9a060e54bf8d69288fbee4904","usage":{"cachedInputTokens":3631687,"inputTokens":102,"model":"claude-opus-5-5","outputTokens":39859,"runtime":"claude","turns":65,"wallClockMs":522732}}],"verification":[{"checks":[],"detail":"paths and tree verified; no suite was run for this kind of work","evaluation":"structural","profile":"none","status":"accepted","submissionHash":"03e2275c3b70043621bd6393e6778c567ce8a8015cdd9cd72a1db8c6ba9b5ae7","verifiedTreeHash":"4b825dc642cb6eb9a060e54bf8d69288fbee4904","verifierVersion":"0.1.0+1b3bcb5e"}]}
