PondPad is an IMD-paired token launchpad on Robinhood Chain (chain id 4663): Solidity 0.8.26, Foundry project in launchpad/contracts (cancun, via-IR), Uniswap v4 hooks. Other areas of the same commit are audited by separate jobs; stay on this one.\nREAD FIRST, in this repository:\n- launchpad/audit/THREAT-MODEL.md: actors and trust, the invariants (section 2), deliberate behaviour that is NOT a finding (section 3) and the severity scale (section 4). Use that scale.\n- launchpad/audit/FINDINGS.md: findings already fixed or accepted in earlier rounds. Do not re-report them unless the fix is wrong. Findings still open there are known; report them again only with a new, worse path. Check that every fix marked fixed for this area is correct and complete and opens no new path (each names its regression test).\n- Design: launchpad/ARCHITECTURE-v1.md. Reasons for every choice: launchpad/DECISIONS.md (cited as D-n).\n- Tests: cd launchpad/contracts && git submodule update --init --recursive && forge test --no-match-contract Fork\nFILES IN THIS AREA (read fully; follow calls into other files when needed):\n- launchpad/contracts/src/PondPadToken.sol\n- launchpad/contracts/src/PadSale.sol\n- launchpad/contracts/src/PaymentSwapper.sol\n- launchpad/contracts/src/IntegratorVault.sol\n- launchpad/contracts/src/PadMarketHook.sol\n- launchpad/contracts/upstream/CappedBurnHook.sol\n- launchpad/contracts/upstream/make_fork.py\n- launchpad/contracts/src/MarketController.sol\n- launchpad/contracts/src/PadBurner.sol\n- launchpad/contracts/src/LiquidityReserve.sol\n- launchpad/contracts/src/FeeSplitter.sol\n$PONDPAD (1B fixed supply) is sold on PadSale, an IMD bonding curve (600M sold, 300M to the pool, target ~8,460 IMD, 1% fee, snipe tax 80% -> 0 over 30 min, 15M per-wallet cap). At graduation the raise and 300M go to MarketController.launch, which opens PadMarketHook: our fork of POOL4's CappedBurnHook (upstream/CappedBurnHook.sol is the original; upstream/make_fork.py generates PadMarketHook.sol from it, so every change is in that script). Changes: IMD is currency0 ($PONDPAD address mined above IMD), ERC-20 quote instead of native ETH, dynamic LP fee 3% -> 1% over 7 days returned from beforeSwap, IMD-sized constants (cap floor 150M, decay 500k/day, 15% of trims to stakers). MarketController owns the hook forever; the only exit is migrate() (approved by the 7-day timelock, run by the team Safe, first 12 months).\nChanged since round 1 (D-78): MarketController.launch measures what openMarket took; migration needs approveMigration (7-day sinkAdmin) and is run only by the migrator (team Safe), and the new hook inherits the placement floor, reference tick and cap (inheritGuards in make_fork.py; floor and cap only raised).\nChanged since round 2 (D-79): IMD returned by an owner closeBackstop or a migration seed earns no keeper tip (untippedQuote, make_fork.py); a closed hook can't be reopened; migrate clears the old hook's allowances; sinkAdmin is immutable (no setSinkAdmin); PadSale.buyWith takes minImd, quoteBuy charges a completing buy only on the IMD it needs, graduation hands stray balances to the controller; new LiquidityReserve holds the 30M reserve until the market opens.\nChanged since round 3 (D-80): MarketController refuses a cap floor below the deploy floor and a decay above 5x the deploy pace; fundInventory refunds only what it pulled (other balances to the splitter / burner); make_fork.py: refTick steps maxRefStep per block elapsed since the last swap, and matured claims are not realised inside a swap while IMD or $PONDPAD is synced; owners are fixed (FixedOwnable); FeeSplitter.distributeToken only $PONDPAD.\nLook hardest at:\n- Did make_fork.py change anything beyond its listed changes? Does the ETH -> ERC-20 quote conversion keep every settle/take/sync correct? Does the dynamic fee leak into cap, trim, burn, backstop or keeper-tip math?\n- PadSale solvency, cap accounting across buyWith/sellFor and payment tokens, snipe tax timing, the completing buy's refund, graduation exactly once with the exact amounts and sqrt price.\n- MarketController: can launch, collectFees, fundInventory, policy setters or migrate ever send pool assets to a wallet, open twice, change openedAt, or migrate into a hostile or already-open hook?\n- Trim/burn/settleClaims/rebalance under adversarial keepers and outside routers (ordering, same block, partial settlement), PadBurner.\n- Sell-side $PONDPAD fees and their split (collectFees -> FeeSplitter.distributeToken).\nReport only issues with a concrete path (who calls what, with which values, what goes wrong), with a Foundry proof where possible.

Nothing lowers inventoryCap except the ratchet in _applyCap, which is rate-limited to capDecayTokensPerDay (<= 2.5M/day after D-80) and only runs while the position holds less than the cap. fundInventory only adds to the cap and migrate -> inheritGuards keeps max(newCap, oldCap), so a lifted cap survives a migration too.\n\nState / input: market open after graduation (position ~300M $PONDPAD, inventoryCap ~300M, capFloor 150M, decay 500k/day). The 48 h timelock executes setCapFloor(X) with X above the position's holdings (400M in the proof; 1e27 or a fat-fingered 1e36 behave the same), then setCapFloor(150_000_000e18).\n\nExpected (controller NatSpec: the floor \"can be raised, and lowered back to that\"; ARCHITECTURE 5.4.2: both settings \"adjustable later\"; hook NatSpec: \"no owner can turn the deflation off\"): the floor is back at 150M and the cap is where the ratchet left it, so the next sell above the cap trims as before.\n\nActual: capFloor() reads 150M but inventoryCap() stays at X. A following 40M sell (position ~310-340M, far above the old cap) emits no Trimmed, totalBurned and retainedQuote do not move, so nothing is burned, nothing goes to stakers and the backstop gets no IMD. From 400M the ratchet needs (400M - holdings)/2.5M days of continuous buying to come back; from 1e27 it never does. The owner can already pause the ratchet reversibly (setCapDecay(0), setRatchetBps(0)); this path is different because it also stops the trims on net selling and cannot be undone, which is not in ARCHITECTURE 5.6's \"can do\" column.\n\nSeverity: Low. Owner-only through the 48 h timelock (visible for the delay), no asset leaves the pool, nothing goes to a wallet, invariant 11's \"owner settings can't let trading trim the position away\" is not broken (it is the opposite direction). It is an owner power whose effect exceeds its documented bound and is irreversible.\n\nFix (preserving the design): in MarketController.setCapFloor refuse a floor above the hook's current cap or holdings, e.g. `if (newFloor > hook.inventoryCap()) revert PolicyOutOfBounds();` (inventory is added through fundInventory, which raises the cap by exactly what it deposits); or, if lifting is wanted, make a floor decrease also set `inventoryCap = max(newFloor, tokensInPool())` in make_fork.py and document it. Add a raise-then-lower regression test (test_market_capFloorAndDecayAreBounded only checks the bounds).\n\nInvariants checked for this finding: 11 (bounded owner settings; no pool asset reaches a wallet: holds), 12 (fee never enters cap math: holds).","line":200,"path":"launchpad/contracts/src/MarketController.sol","proof":"// SPDX-License-Identifier: MIT\npragma solidity 0.8.26;\n\nimport {Test} from \"forge-std/Test.sol\";\nimport {ERC20} from \"solady/tokens/ERC20.sol\";\nimport {PoolManager} from \"v4-core/PoolManager.sol\";\nimport {IPoolManager} from \"v4-core/interfaces/IPoolManager.sol\";\nimport {Hooks} from \"v4-core/libraries/Hooks.sol\";\nimport {TickMath} from \"v4-core/libraries/TickMath.sol\";\nimport {PoolKey} from \"v4-core/types/PoolKey.sol\";\nimport {SwapParams} from \"v4-core/types/PoolOperation.sol\";\nimport {PoolSwapTest} from \"v4-core/test/PoolSwapTest.sol\";\nimport {PadConfig} from \"src/PadConfig.sol\";\nimport {FeeSplitter} from \"src/FeeSplitter.sol\";\nimport {IntegratorVault} from \"src/IntegratorVault.sol\";\nimport {PadSale} from \"src/PadSale.sol\";\nimport {PondPadToken} from \"src/PondPadToken.sol\";\nimport {PadBurner} from \"src/PadBurner.sol\";\nimport {PadMarketHook} from \"src/PadMarketHook.sol\";\nimport {MarketController} from \"src/MarketController.sol\";\n\ncontract MockIMD2 is ERC20 {\n    function name() public pure override returns (string memory) {\n        return \"IMD\";\n    }\n\n    function symbol() public pure override returns (string memory) {\n        return \"IMD\";\n    }\n\n    function mint(address to, uint256 amount) external {\n        _mint(to, amount);\n    }\n}\n\n/// Audit R4-A2: `MarketController.setCapFloor` can lift `inventoryCap` without bound, and lowering the floor back\n/// to the deploy value does not bring the cap back down.

The only working-tree additions are my scratch tests under `test/scratch/` and the findings file.\n\n**What I verified before judging**\n\n- `upstream/make_fork.py` regenerates the committed `PadMarketHook.sol` byte for byte. The full upstream diff contains only the listed changes: ERC-20 quote plumbing (sync, transfer, settle on both payer paths), the dynamic fee returned from `beforeSwap`, IMD constants, the migration helpers, and the round 2 and 3 fixes.\n- The full local suite passes, 182 tests.\n- Both specialist proofs fail on this code for the stated reason.\n- My own probes ran the backstop fill path, a migration in the trim's own block with the band in range, and the supply-lag claim. The fill and migration paths hold every ledger check: claims equal the hook's ERC-6909 balances, real IMD backs retained minus claims, IMD is conserved across the migration, and the keeper tip stays under both the configured reward and the fee on converted principal.\n\n**Findings kept**\n\n1. **Low, with proof.** `MarketController.setCapFloor` raises the hook's cap to any floor above the holdings, and lowering the floor back never lowers the cap. The ratchet is the only way down, at 2.5M per day at most, and `inheritGuards` keeps the lifted cap across a migration. One 48 h timelock action therefore stops every trim, staker share and backstop refill, irreversibly. The two specialist reports described the same mechanism and fix, so they are merged into one finding. The suggested fix refuses a floor above the current cap, or makes a floor decrease reset the cap to the holdings.\n2. **Info.** The hook counts a trim as burned when it only holds ERC-6909 claims. The tokens reach `PadBurner` on settlement and leave supply only when someone calls its `burn`, which no permissionless controller path does. Reproduced: after a 5M sell, settling and collecting fees, supply is unchanged until a manual burn.\n3. **Info.** Six untested paths, merged from three specialist notes: the backstop fill settlement, migration in a trim's block, a pay-first sell router, cap-floor raise then lower, a USDG-paid completing sale buy, and `sellForWithPermit`. All behave as specified when run.\n\n**Invariants checked**\n\nInvariant 10 (sale solvency, 15M cap across payment tokens, graduation once with exact amounts and sqrt price), 11 (market opens once from the sale, no pool asset to a wallet, bounded owner settings, migration guards, `openedAt` fixed), 12 (fork matches upstream except listed changes, fee never enters cap or trim math) and 15 (splitter outputs equal inputs, `distributeToken` only $PONDPAD).

So after the 48 h owner raises the floor to any value above the market's holdings (e.g. 1e27 = 1B $PONDPAD, or simply a fat-fingered 1e36) and later sets it back to the deploy floor (150M), the floor reads 150M again but the cap stays where it was raised to. Consequences: (1) `_applyCap` never finds `held >= inventoryCap`, so no sell is ever trimmed: the burn programme (85% burned / 15% to stakers, THREAT-MODEL 11/12, D-21, ARCHITECTURE 5.4.2 'the burn runs at about capDecayTokensPerDay') and the backstop refill (`retainedQuote` only grows from trims) are off; (2) coming back needs the cap to ratchet from 1e27 to ~300M at <= 2.5M/day, i.e. ~4e20 days: effectively never; (3) `fundInventory` only adds to the cap, and `migrate` -> `inheritGuards(..., oldCap)` keeps `max(newCap, oldCap)`, so a migration into a fresh hook cannot reset it either. The hook's own NatSpec states the design intent that 'no owner can turn the deflation off'; ARCHITECTURE 5.4.2 says the floor is 'adjustable later', which reads as reversible. This is an owner-only path (48 h visible, no funds move, nothing goes to a wallet), hence Low; it is reported because it is irreversible, not listed in ARCHITECTURE 5.6's 'can do' column, and a single mistaken value has permanent effect. Fix options (preserving the design): in `MarketController.setCapFloor`, refuse a floor above `max(initialCapFloor, hook.tokensInPool())` (the floor's purpose is to stop the cap ratcheting below a level, not to lift the cap above the holdings); and/or, in make_fork.py, let a floor decrease also set `inventoryCap = max(newFloor, tokensInPool())` so the floor stays reversible.

Summary of what was done and found:\n\n## Scope and method\n\nRead in full: `THREAT-MODEL.md`, `FINDINGS.md`, `ARCHITECTURE-v1.md`, `DECISIONS.md` (D-77…D-81), all eleven area files, plus `PadConfig`, `Route`, `FixedOwnable`, `Base.t.sol`, `Market.t.sol`, `PadSale.t.sol`, the deploy wiring, and the pinned v4-core settle/sync/take/fee-override internals. Ran the pashov passes (execution trace, periphery, first principles, invariant, asymmetry, boundary, access map) as review passes by one reviewer, not twelve agents.\n\n**Verified:**\n- `make_fork.py` regenerates `src/PadMarketHook.sol` byte-for-byte; the 922-line upstream diff contains only the listed changes (renames, ERC-20 sync/transfer/settle in `_payQuote`/`_addPosition`, `take(quote)`, dynamic fee via `beforeSwap`, IMD constants, migration helpers, R2/R3 fixes). Every settle/take/sync was traced; the fee enters only `currentFee()` and the keeper-tip bound.\n- PadSale math: `x·y ≥ k` holds across buys/sells, `raised == x − x0`, every seller is payable, the completing buy's `net ≥ netNeeded`, `raised ≥ target` at graduation, pool price = `raised/R` within wei.\n- Every fix marked fixed for A2 (R1-A2-1…5, R2-A2-1…7, R3-A2-1…6, R3-A3-2, R3-A3-8) re-read against its path and regression test; none wrong or incomplete.\n- Tests: full local suite 182/182. Scratch work (`test/scratch/`, not kept): a stateful invariant harness (1,920 calls: adversarial pay-first / stale-sync / double-swap routers, owner actions, two migrations per run) holding cap, backing, controller-empty and `openedAt` invariants; 8 scenario tests (pay-first *sell* during claim maturity, trim→migrate same block, exact net raise, keeper tip ≤ fee on fresh trims, sale cap across payment tokens, liquidity-margin fuzz).\n\n**Invariants checked:** 9 (sale part), 10, 11, 12, 15 (splitter), 22 (step-7 wiring).\n\n## Findings (1 Low, 1 Info; no High/Critical)\n\n1. **Low** — `MarketController.setCapFloor` (line 199): raising the floor lifts `inventoryCap` to it, but lowering the floor back never lowers the cap; the ratchet (≤ 2.5M/day), `fundInventory` (adds only) and `migrate` → `inheritGuards` (keeps the max) can't undo it. One 48 h action (`setCapFloor(1e27)` then `setCapFloor(150M)`) leaves the floor reading 150M while trims — the burn programme and the backstop refill — are off for good. Owner-only and no funds move, hence Low; carries a self-contained proof that fails now (a 40M sell after the restore burns 0) and passes once the raise is bounded or a lowering also lowers the cap.\n2. **Info** — coverage edges at `Market.t.sol:668`: pay-first sell router, trim-and-migrate in the same block, floor raise-then-lower, stale `sync` (with the note that Foundry resets transient storage between top-level calls).\n\nI dropped a third draft entry about in-swap claim settlement after re-tracing it: `_maybeRedeemMaturedClaims` runs before `_collectFees`, so the first swap of each new block does settle the prior block's claims — not a defect.","treeHash":null,"usage":{"cachedInputTokens":9728080,"inputTokens":840,"model":"claude-fable-5-1","outputTokens":125589,"runtime":"claude","turns":68,"wallClockMs":2813944}},{"artifacts":[],"attempt":1,"bundleHash":null,"device":"fa2b7fcb5f53535a","findings":[{"citation":"resolved","description":"`MarketController.setCapFloor` only checks `newFloor >= initialCapFloor` (150M) and forwards to `PadMarketHook.setCapFloor`, which does `if (inventoryCap < newFloor) inventoryCap = newFloor;` (src/PadMarketHook.sol:447). Raising the floor therefore raises the cap to any value, and lowering the floor back to 150M leaves the cap where it was lifted: the hook's cap only ever comes down through the ratchet, which is rate-limited to `capDecayTokensPerDay` (at most 2.5M/day, D-80). The controller's own NatSpec says the floor \"can be raised, and lowered back to that\", and THREAT-MODEL invariant 11 / ARCHITECTURE 5.4.1 present the floor as a bounded policy knob; neither says a floor raise permanently resets the cap. Consequence: one 48 h timelock operation `setCapFloor(X)` with X far above the pool's holdings (e.g. 1e30) means `held > inventoryCap` can never be true again, so no sell is ever trimmed, nothing is burned, no IMD reaches the backstop and stakers receive no trim share, for ever (the ratchet can reduce the cap by at most 2.5M/day, so from 1e30 it never returns). Even a modest raise undoes all burn progress: after 10 days of ratcheting (cap 295M), `setCapFloor(400M)` then `setCapFloor(150M)` leaves the cap at 400M, so a 40M sell that would have trimmed ~35M trims nothing. This is not a theft and needs the 48 h owner, so Low: an owner power that exceeds its documented bound (THREAT-MODEL 3: report ways to exceed listed powers). Minimal fix preserving the design: in `MarketController.setCapFloor` refuse a floor above the hook's current `inventoryCap` (`if (newFloor > hook.inventoryCap()) revert PolicyOutOfBounds();`), so the floor moves only between 150M and the cap and can never lift the cap (inventory is added through `fundInventory`, which raises the cap by exactly what it deposits); or, if lifting is wanted, document it and make lowering the floor set `inventoryCap = max(newFloor, tokensInPool())`. Checked invariants: 11 (owner settings bounded; no asset leaves the pool here, so only the \"bounded settings\" part is affected), 12 (fee never enters cap math: unaffected).","line":200,"path":"launchpad/contracts/src/MarketController.sol","proof":"// SPDX-License-Identifier: MIT\npragma solidity 0.8.26;\n\nimport {Test} from \"forge-std/Test.sol\";\nimport {ERC20} from \"solady/tokens/ERC20.sol\";\nimport {PoolManager} from \"v4-core/PoolManager.sol\";\nimport {IPoolManager} from \"v4-core/interfaces/IPoolManager.sol\";\nimport {Hooks} from \"v4-core/libraries/Hooks.sol\";\nimport {TickMath} from \"v4-core/libraries/TickMath.sol\";\nimport {PoolKey} from \"v4-core/types/PoolKey.sol\";\nimport {SwapParams} from \"v4-core/types/PoolOperation.sol\";\nimport {PoolSwapTest} from \"v4-core/test/PoolSwapTest.sol\";\nimport {PadConfig} from \"src/PadConfig.sol\";\nimport {FeeSplitter} from \"src/FeeSplitter.sol\";\nimport {IntegratorVault} from \"src/IntegratorVault.sol\";\nimport {PadSale} from \"src/PadSale.sol\";\nimport {PondPadToken} from \"src/PondPadToken.sol\";\nimport {PadBurner} from \"src/PadBurner.sol\";\nimport {PadMarketHook} from \"src/PadMarketHook.sol\";\nimport {MarketController} from \"src/MarketController.sol\";\n\ncontract MockIMD2 is ERC20 {\n    function name() public pure override returns (string memory) {\n        return \"IMD\";\n    }\n\n    function symbol() public pure override returns (string memory) {\n        return \"IMD\";\n    }\n\n    function mint(address to, uint256 amount) external {\n        _mint(to, amount);\n    }\n}\n\n/// Audit R4-A2: `MarketController.setCapFloor` can lift `inventoryCap` without bound, and lowering the floor back\n/// to the deploy value does not bring the cap back down.

No tracked file was changed; only the untracked scratch tests and the findings file were added.\n\n**What I checked**\n\n- The generator `upstream/make_fork.py` reproduces `src/PadMarketHook.sol` byte for byte, and the full diff against the upstream `CappedBurnHook.sol` contains only the listed changes (IMD quote with sync/transfer/settle, dynamic fee via `beforeSwap`, IMD-sized constants, migration helpers, and the round 2 and 3 fixes). Every settle, take and sync in the ERC-20 conversion is in the hook's own unlock or correctly offset by ERC-6909 claims, and the dynamic fee reaches only the pool fee and the keeper-tip ceiling.\n- PadSale: curve solvency (`raised == x - x0`, balance equals `raised`), the per-wallet cap across buys and sells, snipe-tax timing, the completing buy's refund (pays exactly `grossNeeded`), and one-time graduation with the exact amounts and sqrt price.\n- MarketController: launch once, `openedAt` fixed, fee collection to the splitter only, `fundInventory` refunds, policy bounds, and migration only by the migrator into the approved unopened hook with inherited guards.\n- Adversarial keeper and router paths: same-block trims and rebalances, pay-first routers, migration with a partially filled backstop and claims minted in the migration block (IMD conserved to 1 wei), and a manufactured backstop fill at the 3% fee (tip of 18 IMD against 5.7M $PONDPAD in fees paid).\n- Invariants 10, 11, 12 and the sale part of 9 hold.

A rename-normalised diff against `upstream/CappedBurnHook.sol` shows only the listed changes (IMD quote plumbing, dynamic fee via `beforeSwap`, IMD constants, `seedRetainedQuote`/`inheritFeeSchedule`/`inheritGuards`, `untippedQuote`, never-reopen, per-block `refTick` catch-up, synced-currency skip). `currentFee()` is read only in `beforeSwap` and `_keeperRewardDue`; nothing in cap/trim/burn/backstop reads it. Every former `settle{value}`/`safeTransferETH`/`receive()` is replaced by `sync`+transfer+`settle` or `safeTransfer`, all inside the hook's own unlock; `take`s of IMD inside a swapper's unlock are only in `_redeemClaims`, which the R3-A2-3 skip guards. I traced ledger backing (`balance + quoteClaims ≥ retainedQuote`; 6909 balances = claim ledgers) with a scratch test over trim/rebalance/settle interleavings in the same and later blocks — holds.\n\n**PadSale (invariant 10).** Proved solvency: `x·y ≥ k` after every trade, `y + sold == y0`, so any sell's `gross ≤ x − x0 == raised`; a 512-run random buy/sell fuzz confirmed `IMD balance == raised`, `x − x0 == raised`, token balance `== 900M − sold`. The completing buy charges fee/snipe only on `grossNeeded`, refunds the rest in IMD, lands `x_end = 2·target + 1 wei`, pool opens at `raised/300M` = curve's `x/y` (±rounding); launch leftovers are 300 $PONDPAD burned and ~0.008 IMD to the splitter. Per-wallet cap is cumulative over the whole sale; snipe tax decays from `startTime`; `minImd` bounds the payment swap; `graduate()` is the only fallback and cannot be blocked or front-run (pool init is hook-only).\n\n**MarketController / migration (invariant 11).** `launch` measures what `openMarket` took, is sale-only and once; `openedAt` never changes; `fundInventory` refunds only its own leftovers; policy setters are bounded (floor ≥ 150M, decay ≤ 2.5M/day, reward share ≤ 30%, tip < threshold ≤ 40 IMD); no path reaches `withdrawRetainedQuote`, ownership transfer or `closeMarket` outside `migrate`. Stress-tested `migrate` with a partially filled backstop, a trim in the migration block, pending claims and a different tick spacing on the new hook: old hook ends with zero balances/claims/band, controller holds nothing, the new hook inherits price, fee clock, floor, ref tick and cap, seeded IMD is untipped. Closed hooks can't reopen; a hook whose pool was pre-initialised can't be a target.\n\n**Keeper/tip economics.** Tip is bounded by `currentFee × work` so manufacturing idle IMD or a fill costs at least the tip; `untippedQuote` correctly excludes owner-close and migration-seed IMD in every ordering I tried. `rebalance` cannot be DoSed (band is always strictly above spot). Reward-share wash trading beyond the first trim is limited to the paced decay allowance — the documented burn programme running at its intended rate, not a defect.\n\n**Sell-side fees (invariant 15).** `collectFees → withdrawFees → distribute/distributeToken` splits $PONDPAD 40/25/20/15 exactly; `distributeToken` accepts only $PONDPAD.\n\n### Earlier fixes for this area\nR1-A2-1/2/3/4/5, R2-A2-1/2/3/4/5/7, R3-A2-1/3/5 all verified correct and complete; none opens a new path.\n\n### Reported\n- **Info** — `totalBurned`/`Trimmed` count tokens as burned while they sit in `PadBurner`; no permissionless controller path calls `burn()`, so `totalSupply` lags the hook's figures.

Nothing unlisted.\n- **Math passes** (precision, boundary, numerical-gap guides): sale curve (`x·y ≥ k` kept, `y − remaining ≡ 600M` so `netNeeded = 2E − x` exactly, completing-buy `grossNeeded`/refund rounding always leaves `net ≥ netNeeded`, sell `gross ≤ raised` since circulating $PONDPAD = `sold` during the sale), `openingSqrtPriceX96` and `fullRangeLiquidity` (512-bit intermediates, 1 ppm haircut vs v4's round-up), cap ratchet clock (`lastCapDecayAt` can't pass `block.timestamp`; `uint128` decay bound), trim rounding (pool-favouring, non-compounding), band inversion (floor twice → `quoteUsed ≤ quoteAmount`), `currentFee()` monotone 30 000→10 000, `_observeTick` int256 step with `MAX_CATCHUP_BLOCKS`, keeper tip ≤ fee paid at trim time (fee only decreases).\n- **Settle/take/sync audit:** every `sync→transfer→settle` and `burn→take` in the hook traced; the only takes inside a swapper's unlock are the matured-claim redemptions, and the R3-A2-3 guard covers both the IMD (buy) and $PONDPAD (sell) pay-first cases.\n- **Invariants checked:** 9 (sale half), 10, 11, 12, 15 (`distributeToken` only $PONDPAD). All hold.\n- **Earlier fixes in this area re-verified against their paths:** R1-A2-1/2/3/4/5, R2-A2-1/2/3/4/5/7, R3-A2-1/3/5/6 — each correct, complete, with its regression test passing; no new path opened.\n- **Tests:** full non-fork suite 182/182 pass. My probes (`test/scratch/Probe*.t.sol`, 13 tests incl. 512-run fuzzes) exercised the untested backstop **fill** path (tip 1 IMD vs ~40 IMD of fees paid), ledger conservation under random op ordering (claims == PM ERC-6909 balances, `retainedQuote − quoteClaims` == hook balance, cap/floor), migration with the band in range (old hook ≤ 1 wei, controller empty), launch across the whole 1k–50k IMD target range, `quoteBuy == buyWith` inside the snipe window, USDG-paid completing buy with refund, pay-first sell router, upkeep calls inside an outside unlock (all revert cleanly), a 5M-block gap, and `sellForWithPermit`.\n\n### Leads examined and rejected (not reported)\n- `_addBandLiquidity` double-ceil could revert `IncorrectQuoteAmount` only if the exact real-valued amount is an integer — measure-zero, self-healing on the next trim.\n- `setCapFloor` is unbounded upward (can park the cap above holdings and stop trims) — within the listed 48 h power; invariant 11 bounds only the floor's lower side.\n- 1 ppm haircut burns ~300 $PONDPAD per migration — D-40 \"dust is burned\", no wallet.\n- Keeper tip is paid from backstop IMD — POOL4's design, fee-bounded, listed.\n\n### Limitations\nFork tests (`FORK_RPC`) not run (no network needed for this review; local suite only); no Slither; fuzz at 512 runs (launch fuzz at 48 runs, ~100 buys each).","treeHash":null,"usage":{"cachedInputTokens":8061565,"inputTokens":814,"model":"claude-fable-5-1","outputTokens":98245,"runtime":"claude","turns":66,"wallClockMs":2567573}}],"verification":[]}
