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.\nChanged since round 4 (D-83): MarketController.setCapFloor also refuses a floor above the hook's current inventoryCap, so a floor change can't lift the cap and stop the trims (R4-A2-1); collectFees also calls PadBurner.burn() (R4-A2-2); make_fork.py adds referenceTick() (the reference as the next swap's _observeTick will set it: refTick caught up toward the last swapped block's close, refTick itself once this block had a swap), which _observeTick now uses and PadBuyer reads (R4-A3-3). Since the check before round 5 (D-84): make_fork.py lowers the default maxRefStep from POOL4's 200 to 100 ticks per Ethereum block (listed change 9, audit R2-A3-6; setMaxRefStep's 1..2000 range and its 48 h owner unchanged), so the reference moves at most ~1% per block; testFuzz_market_capInvariantAtBothFeeLevels no longer runs its trader out of $PONDPAD (P5-1, test only; test_market_capFuzzReplaysTheFlakySeed replays the failing input).\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).\n\nReport only issues with a concrete path (who calls what, with which values, what goes wrong), with a Foundry proof where possible.

Since D-80 (R3-A3-2) the stored `refTick` is only a lagging snapshot: the effective reference, which `_observeTick` will store at the next swap and which PadBuyer reads (R4-A3-3), is `referenceTick()` = `refTick` advanced `maxRefStep` per Ethereum block elapsed since the last swapped block, so after quiet blocks it has caught up with the price that stood. The new hook's `openMarket` sets `refBlock = block.number` and `curBlockTick = currentTick()`, and `inheritGuards` then overwrites `refTick` with the stale value. In the migration block `next.referenceTick()` therefore equals the stale `refTick`, while `old.referenceTick()` a moment earlier was caught up; the catch-up restarts from zero at 100 ticks per block. PRECHECK-5 (R4-A3-3 note) recorded this as 'slower, never faster' and not a problem. It is not only slower: when the last swapped block was a dump (tick up), the stale reference sits on the dearer side of spot, which is exactly the state R3-A3-2 fixed. PadBuyer's guard `spot < ref - maxDeviationTicks` passes for any spot cheaper than the stale reference, and its price limit `ref - maxDeviation - maxSlippage` is computed from the stale reference, so a sandwicher can pump $PONDPAD up to ~200 ticks dearer than the stale reference and PadBuyer buys its chunk there instead of refusing. In the reproduction PadBuyer pays 24.6% above the price the old hook's caught-up reference would have enforced (the same hook refuses the same pump with PriceOutOfRange when not migrated). The gap persists for (stale gap / maxRefStep) blocks after the migration (24 blocks, ~5 minutes, in the reproduction) and also feeds `_updateDeploymentFloor`'s decay target (negligible over that window). Severity Low: the attacker in the reproduction loses ~45 IMD in pump/dump fees to make PadBuyer overpay ~6 IMD of value on one 25 IMD chunk (one chunk per 10-minute interval, and the window closes within minutes), the trigger needs a big single-block move followed by swap-less blocks right before the Safe's migration, and the Safe chooses the block. Still, THREAT-MODEL invariant 11 says a migration keeps the reference tick, and invariant 14 says PadBuyer reads the caught-up reference; after a migration neither is true for the first blocks. Fix: pass the caught-up reference, `old.referenceTick()`, at line 315 (identical to `old.refTick()` whenever the migration block already had a swap). Optionally also let `inheritGuards` take the old `curBlockTick`/`refBlock` so the step count continues; passing `referenceTick()` alone is enough to close the regression.","line":315,"path":"launchpad/contracts/src/MarketController.sol","reproduction":"Setup as in test/Market.t.sol MarketBase (PadMarketHook with tickSpacing 200, maxRefStep 100 default; MarketController; PadSale graduated; PadBuyer at its defaults, maxDeviation 100 / maxSlippage 100, funded with 25 IMD). 1) Trader sells 40,000,000 $PONDPAD in one block: spot tick moves from ~104,667 to 107,199; the stored refTick is 104,767 (one 100-tick step). 2) Roll 40 Ethereum blocks with no swap: `market.referenceTick()` == 107,199 (caught up); `market.refTick()` still 104,767. 3) 7-day timelock `approveMigration(next)`, migrator `migrate(next)` with no swap in that block.

I diffed the upstream file with the mechanical renames applied against the generated hook. Every delta is a listed change (ERC-20 quote plumbing, dynamic fee, IMD constants, migration helpers, round 2 to 4 fixes, the D-84 default step). No forbidden pattern remains.\n- ETH to ERC-20 conversion: every `settle` is preceded by `sync` plus transfer, every `take` of IMD goes to the hook, and the hook's own unlock never nests. The dynamic fee is read only in `beforeSwap` and the keeper-tip bound, never in cap, trim, burn or backstop math.\n- PadSale: solvency (`x - x0 == raised`, real IMD equals `raised`), the whole-sale wallet cap, snipe tax timing, the completing buy's refund and `minImd` bound, graduation exactly once with the exact raise and 300M at the curve's final sqrt price. A 300-run random buy/sell fuzz across eight wallets confirmed sale IMD equals `raised` at every step, every holder can exit, and graduation hands over exact amounts.\n- MarketController: `launch` once, `openedAt` fixed, `fundInventory` refunds only its own leftovers, `setCapFloor`/`setCapDecay` bounds, `migrate` guards (approved hook, migrator only, unopened hook, same pair and owner and sinks, allowances cleared, no wallet ever paid).\n- Trim, claims, rebalance and keeper tip under same-block and pay-first-router orderings. All controller and hook entry points route through `unlock`, so an outside router cannot call them mid-swap.\n- Sell-side $PONDPAD split: all four recipients can forward or hold $PONDPAD.\n- Every round 1 to 4 fix marked fixed in this area is in place and its regression test runs. The full local suite passed, 186 of 186 tests.\n\n**The finding (Low)**\n\n`MarketController.migrate` passes the old hook's stored `refTick` to `inheritGuards`, not the caught-up `referenceTick()` that PadBuyer reads. After a large single-block move followed by quiet blocks, the new hook's reference regresses to the stale value and restarts its 100-tick-per-block catch-up. PRECHECK-5 recorded this as \"slower, never faster\"; the worse path is that the stale value sits on the dearer side of spot, so PadBuyer's guard passes a pump it would otherwise refuse. In the reproduction PadBuyer paid 24.6% above the correct reference price for one 25 IMD chunk, while the identical pump on the un-migrated hook reverted with `PriceOutOfRange`. The attacker loses about 45 IMD to make the buyer overpay about 6 IMD, so it is griefing, not profit. Fix: pass `old.referenceTick()` at `MarketController.sol:315`.\n\n**Invariants checked**: 10, 11, 12 fully; 14 and 15 where they touch this area (PadBuyer's reference read, the splitter's $PONDPAD split).

The stored `refTick` only moves at the next swap. `MarketController.migrate` reads `old.refTick()` (the stored, un-caught-up value) and hands it to `inheritGuards`, which sets the new hook's `refTick` to it while `openMarket` has already set `curBlockTick` to the migration-block price and `refBlock` to the migration block.

Bounded: PadBuyer buys at most `maxChunk` (25 IMD default, 500 max) per `interval`, the catch-up closes the gap at 100 ticks per block, a migration needs the 7-day approval and the Safe, and the pump itself costs more fee than the chunk at the defaults, so no profitable path at the shipped settings; it is the stated bound that fails.

Reentry from an ETH payout is blocked while the PoolManager is unlocked.\n- **Invariant 11 (controller):** launch opens once at the curve's price and measures what the hook took, collectFees and fundInventory pay no wallet, migrate only moves into an unopened hook owned by the controller with the same sinks, and the untipped-quote accounting holds across closeBackstop, seeds and fill settlements.\n- **Invariant 12 (fork):** regenerating `PadMarketHook.sol` from `make_fork.py` reproduces the committed file byte for byte, the full diff against upstream contains only the listed changes, and every sync, transfer, settle, mint, burn and take in the ERC-20 quote conversion is ordered correctly. `currentFee()` is read only by `beforeSwap` and the keeper-tip bound.\n- **Invariant 15:** `distributeToken` is restricted to $PONDPAD and outputs equal inputs.\n- Every A2 fix from rounds 1 to 4 was re-read against its regression test. All 186 non-fork tests pass on this commit.\n\n**Findings.**\n- **Low, `MarketController.migrate` line 315:** it carries `old.refTick()`, the stored value, instead of `old.referenceTick()`, so the new market's reference restarts behind the price the market held during quiet blocks before the migration. In the probe a 2,433-tick crash followed by 30 quiet blocks left the migrated hook's reference 24% behind spot, which is the state the R3-A3-2 fix removed. Bounded by PadBuyer's chunk size and unprofitable at the defaults.\n- **Low, `MarketController.setCapFloor` line 205:** a floor scheduled at the current cap is reverted by any buy during the 48 h delay, because the ratchet lowers the cap by the accrued allowance. A 1 IMD buy one hour after open was enough. The documented \"raise the floor to the cap to hold it\" use is unreachable through the timelock; griefing only, no loss.\n\n**Not reported.** Keeper tips on a seeded band that later fills, banked decay allowance after quiet days, and the owner's rebalance kill switch are upstream POOL4 behaviour inside the listed powers.

Nothing ties the add to the price the call was sized for. The owner is the 48 h PondPadTimelock whose executor role is address(0) (script/Deploy.s.sol:313, 'anyone'), so the call data (liquidity, maxima) is public for two days and a third party picks the block it runs in. With IMD as currency0, buying $PONDPAD lowers the tick and raises the IMD that a fixed full-range liquidity needs (amount0 ~ L/sqrtP) while lowering the $PONDPAD it needs, so the two maxima bound the price only loosely. A proposal needs slack on maximumImdAmount or an ordinary 48 h price move makes it revert, and that slack is the attacker's room: pump $PONDPAD until quoteRequired just fits maximumImdAmount, execute the queued operation (the protocol adds the 30M reserve plus ~IMD at the pumped price), sell back into the deepened pool. The round trip returns more IMD than it cost; the difference is the impermanent loss on the liquidity the position just added. Reproduced with the deploy parameters (tick spacing 200, cap floor 150M, decay 500k/day, market opened by launch with 8,460 IMD + 300M $PONDPAD, day 8 so the fee is at its 1% floor): with maximumImdAmount at 1.5x the IMD the liquidity needs at the proposal price, a 4,200 IMD pump + execute + sell-back ends with the attacker 56.69 IMD richer; at 2x slack (8,400 IMD pump) 262.23 IMD richer. The same round trips without the add lose 69.97 IMD (fees). With tight slack the other failure appears: at 10% slack a 900 IMD pump (about 9 IMD of fees) makes the execution revert IncorrectQuoteAmount(935.10e18, 930.60e18), so the Safe must re-propose and wait 48 h again, repeatably (a dump makes it revert TokenAmountExceeded instead). THREAT-MODEL invariant 11's literal text holds (no asset goes to a wallet) but value leaves the market position to the sandwicher; bounded by the reserve size and the chosen slack, so Medium. The suite only funds at the unmoved price with 10x IMD slack (test_market_fundInventoryRefundsOnlyItsOwnLeftovers). Fix (keeps the design): make the add price-aware so the Safe can leave generous amount maxima safely, e.g. take a sqrtPrice (or tick) band in fundInventory and revert when hook.currentSqrtPriceX96() is outside it, or a max tick distance from hook.referenceTick() (the block-lagged reference PadBuyer already uses); alternatively size the liquidity on-chain from the two amounts at the live price only when that price is inside the band.

The stored refTick itself only moves at the next swap. migrate reads old.refTick() (line 315) and passes it to inheritGuards, which writes it straight into the new hook's refTick (PadMarketHook.sol:699) after openMarket set curBlockTick to the migration-block tick and refBlock to the migration block. So when the last swapped block was a move followed by quiet blocks, old.referenceTick() had caught up with the price that stood, but next.referenceTick() equals the stale stored value in the migration block and then advances only maxRefStep (100) ticks per block toward the migration price. The three specialists (audit_economics, audit_permissions, audit_flow) reported this same defect; merged here. Reproduced: after a 40M $PONDPAD sell the tick goes from 104,764 to 107,197; the stored refTick stays 104,764; after 40 quiet blocks old.referenceTick() == 107,197 while old.refTick() == 104,764; after migrate, next.referenceTick() == 104,764 in the migration block and 104,864 a block later (it needs ~24 blocks to reach 107,197). Consequence: PadBuyer (reads referenceTick(), guard spot >= ref - 100, limit ref - 200) accepts a pump of spot into the stale reference's band: after the migration an attacker buys spot up to 104,673 and PadBuyer.buy() fills 844,962 $PONDPAD for ~24.875 IMD, against 1,124,700 at the caught-up reference price (2,487 bps overpay); the same pump on the un-migrated hook (spot 104,896 vs reference 107,197) makes buy() revert PriceOutOfRange. The stale lower refTick is also _updateDeploymentFloor's decay target for those blocks (no effect on placement since lower = max(spot + 1, floor)). THREAT-MODEL invariant 11 says a migration keeps 'the reference tick' and invariant 14 states PadBuyer's bound against the pre-pump price (maxRefStep + maxDeviation + maxSlippage per block); for the blocks after such a migration neither holds. Severity Low: at the defaults the pump (about 900 IMD of buys, ~2% round-trip fees) costs the attacker far more than PadBuyer's overpay on one 25 IMD chunk (~6 IMD), the window closes within ~24 blocks (one chunk per 10-minute interval), and it needs the Safe to migrate right after a move with no swap since; at the owner's maximum chunk (500 IMD) the sandwich would turn profitable. Fix: read old.referenceTick() instead of old.refTick() at line 315 (identical whenever the migration block already had a swap, since closeMarket is not a swap); optionally let inheritGuards also set curBlockTick so the catch-up continues.

In the scratch run it filled at tick 104,581 while the market stood at 107,179 one block earlier, about 26% above, where a sandwich takes the difference on each chunk. This reopens the R3-A3-2 path across a migration and leaves the R4-A3-3 fix incomplete. The fix is to inherit `old.referenceTick()`. The proof file is `launchpad/contracts/test/scratch/MigrateStaleReference.t.sol`. Both of its tests fail on the current code and pass with that one-token change, which I checked in a temporary copy.\n\n**What I checked and found sound.**\n- `make_fork.py` regenerates `PadMarketHook.sol` byte for byte. The diff against the upstream contains only the nine listed changes plus comments and one unused error removed.\n- The ETH to ERC-20 conversion: every `settle{value}` became sync, transfer, settle. Every native take, mint and burn now names IMD. `closeMarket` reads the IMD balance. No native-currency reference remains.\n- The dynamic fee enters only the pool key, `beforeSwap` and the keeper-tip ceiling. Cap, trim, burn and backstop math read principal from `positionLiquidity` and the price, never the fee.\n- PadSale solvency and the invariant `raised == x - x0` hold through buys, sells, the completing buy's refund, the per-wallet cap, the snipe tax, and ETH and USDG payments. Graduation runs once with the exact net raise and the curve's final price.\n- MarketController: `launch` only from the sale and once, `openedAt` never changes, no path pays a wallet except `fundInventory`'s refund of the owner's own unused tokens, and `migrate` needs the 7-day approval plus the Safe inside 12 months.\n- Keeper ordering: same-block trim, settle, rebalance, owner close and redeploy keep the retained IMD backed by claims plus balance and pay no tip on owner-returned IMD. A band fill settles with the tip bounded by the fee on measured work.\n- Sell-side $PONDPAD fees reach the splitter and split 40/25/20/15.\n\nInvariants checked: 10, 11 and 12 in full, plus the parts of 14 and 15 that the market touches. The full non-fork suite passes (186 tests).

The only bounds on the amounts are the two maxima; nothing checks the price against the one the proposal was sized for (hook.fundInventory -> _addPosition only enforces quoteRequired <= maxQuote and tokensRequired <= maxTokens). The call is behind the 48 h timelock (THREAT-MODEL section 1, D-57): its parameters are public for two days and the timelock's executor role is open to anyone, so a third party chooses the block it runs in. Because IMD is currency0, buying $PONDPAD lowers the tick and raises the IMD a given liquidity needs (amount0 ~ L/sqrt(p)) while lowering the $PONDPAD it needs; a proposal therefore has to carry slack on maximumImdAmount or a normal price move during the delay makes the execution revert. That slack is exactly the room an attacker has: pump $PONDPAD up to the point where quoteRequired still fits maximumImdAmount, execute the queued fundInventory (the protocol adds its 30M reserve at the pumped price), then sell back into the deepened pool. The round trip returns more IMD than it cost; the difference is the impermanent loss the market position takes on the liquidity it just added (THREAT-MODEL invariant 11's 'no path sends inventory to a wallet' holds literally, but value leaves the position to the sandwicher). Measured with the deploy parameters (tick spacing 200, cap floor 150M, decay 500k/day), the full 30M reserve (~846 IMD of IMD at the launch price), the fee at its 1% floor (day 8+): slack 1.1x -> attacker loses 9.3 IMD; slack 1.5x -> attacker GAINS 59.3 IMD (pump 4,272 IMD); slack 2x -> gains 270.8 IMD (pump 8,545 IMD); slack 3x -> gains 856 IMD (pump 17,090 IMD). The same round trips without the liquidity add lose 67 IMD at 4,000 IMD size. At the 3% opening fee the 1.5x and 2x cases are still unprofitable (-89 and -0.08 IMD) and 3x gains 373 IMD. The flip side at tight slack is griefing: with 10% slack a ~850 IMD pump (about 17 IMD of fees) makes the execution revert IncorrectQuoteAmount (a dump makes it revert TokenAmountExceeded), so the Safe must re-propose and wait another 48 h, repeatably. Neither path is exercised by the suite: test_market_fundInventoryRefundsOnlyItsOwnLeftovers funds at the unmoved price with 10x IMD slack. Fix (preserves the design): make fundInventory price-aware so the Safe can set generous amount maxima safely, e.g. take a sqrtPrice range (or a max tick deviation from hook.referenceTick(), the block-lagged reference PadBuyer already uses) and revert when the live price is outside it; alternatively compute liquidity on-chain from the two amounts at the live price only when that price is within the band.

Queued call: fundInventory(L, 30_000_000e18, maxImd) with L = fullRangeLiquidity(spot, 1e30, 30M, 200) (the liquidity 30M buys at the proposal price) and maxImd = 1.5 x the ~846 IMD that L needs at that price. Attacker (any address, 4,272 IMD): (1) swap 4,272 IMD -> $PONDPAD through any v4 router (price moves toward the IMD maximum); (2) execute the queued timelock operation (fundInventory succeeds: quoteRequired <= maxImd, tokensRequired < 30M); (3) sell every $PONDPAD bought back. Expected: a buy-then-sell round trip in a 1%-fee pool costs the trader money (about -67 IMD for this size without the add). Actual: the attacker ends with 59.35 IMD more than it started with (test log: attacker IMD delta 59349219272256579891 wei); the market position, having added liquidity at the pumped price, is worth correspondingly less.

The `retainedQuote == quoteClaims + real IMD` book balances across every writer.\n- **PadSale**: x0 = target, k, curve-end price = raise/300M exactly; the completing buy overshoots the target by 1 wei; rounding favours the curve on both sides; `raised == x − x0 == IMD balance`; snipe-tax boundaries; wallet cap across the sale; graduation once with the exact amounts and sqrt price (300 tokens of 1-ppm liquidity dust burned, as D-39 documents).\n- **MarketController**: launch measured around `openMarket`, `openedAt` written once, cap floor and decay bounds, migration guards and inherited floor/reference/cap, `_copyPolicy` ordering, allowance clean-up.\n- **Hook paths**: trim and ratchet rounding, decay-clock remainder, `_alignUp` with negative ticks, backstop liquidity inversion never exceeding the IMD supplied at these tick levels, keeper tip and `untippedQuote` clamp, matured-claims guard with synced currency, same-block rebalance/settle, sell-side $PONDPAD fee split recipients (all can move the token on).\n- **THREAT-MODEL invariants** checked: 10, 11, 12, and the $PONDPAD part of 15.
