• 1.mediumAnyone can stall a coin's holder stream indefinitely: funding it inside an outside PoolManager unlock resets the stream clock without releasing the share that was duelaunchpad/contracts/src/CreatorVault.sol:134

          _releaseToHolders(coin);
          HolderStream storage st = holderStreamOf[coin];
          uint256 remaining = st.remaining + amount;
          st.remaining = uint128(remaining);
          st.ratePerSecond = uint128((remaining + HOLDER_STREAM_PERIOD - 1) / HOLDER_STREAM_PERIOD);
          st.lastReleaseAt = uint64(block.timestamp);

  _fundHolders first calls _releaseToHolders, which deliberately releases nothing while an outside caller holds the PoolManager unlock (line 148, D-78), and then unconditionally sets lastReleaseAt = block.timestamp and re-spreads the whole remainder over a fresh 7 days. _fundHolders never learns that the release was skipped, so the time accrued since the last release (up to one day's share) is folded back into remaining and the clock restarts.

  Three permissionless entry points reach it: fundHolders(coin, amount) for any registered coin with any amount >= 1 wei, claim(coin) when the coin's recipient is the coin itself (any non-zero vault balance, refilled by every router trade through the hook flush), and SwarmBudget.sweepToHolders(coin); ctoSetRecipient reaches it too when the old recipient was the coin.

  An attacker who wraps fundHolders(coin, 1) in their own poolManager.unlock callback once per day (Robinhood blocks are sub-second and gas is cheap) keeps elapsed near zero for the keeper's daily releaseToHolders, so holder-routed creator fees and swept swarm budgets (the only path by which they reach holders since R1-A4-1) never arrive while the attacker keeps paying gas plus 1 wei per call.

  No IMD is lost: remaining is preserved and the stream resumes when the attacker stops. This is griefing that costs the attacker far less than it costs the holders, and a DoS of the D-78 payout path, hence Medium (two specialists rated it Medium, two Low).

  A related, milder variant needs no unlock: every top-up, honest or a 1-wei fundHolders every hour, re-rates the remainder over 7 days after releasing first, so the linear 7-day stream becomes an exponential decay (after 7 days of hourly 1-wei top-ups 2.567 of 7 IMD are still unpaid; 37%). That part follows from the documented 'reset the rate so the whole remainder pays out over HOLDER_STREAM_PERIOD from now' design; the in-unlock clock wipe does not.

  Fix: in _fundHolders, keep lastReleaseAt (and let the next release pay the skipped share) when _releaseToHolders could not release because the PoolManager was unlocked, e.g. have _releaseToHolders return a 'skipped' flag, or revert fundHolders / claim-to-coin / sweepToHolders while IHolderCoin(coin).poolManager().isUnlocked(), as the curve does for trades. The attached proof passes with either fix.

  Checked against THREAT-MODEL invariant 6 (lumps released through the holder stream over ~7 days); merges specialist findings 1ea59d2b, 36e4e9a0, 8a9210c7 and c6dc976e.

  whole finding

  Setup (Proof_36e4e9a01ffd / test/scratch/Judge.t.sol): launch a no-tax coin; alice buys 1,000 IMD through PadRouter (5 IMD creator fee in the vault); the creator calls vault.setRecipient(coin, coin); anyone calls vault.claim(coin): holderStreamOf(coin).remaining = 5e18, ratePerSecond = ceil(5e18 / 604800) = 8267195767196.

  Warp +1 day: vault.releasableToHolders(coin) = 714285714285734400 (one day's share).

  A contract approves 1 wei IMD to the vault, calls poolManager.unlock and inside unlockCallback calls vault.fundHolders(coin, 1).

  Expected: the day's share is released first or the call is refused while unlocked.

  Actual: PadToken.totalDividendsDistributed() stays 0, releasableToHolders(coin) == 0, remaining == 5e18 + 1, lastReleaseAt == now.

  Repeating the wrapped 1-wei call every hour for 7 days while releaseToHolders is called once a day pays holders exactly 0 (JudgeTest.test_stallInsideUnlockPaysNothing: paid == 0, remaining == 7e18 + 168).

  Without the unlock, hourly 1-wei top-ups leave 2567472868092292168 of 7e18 unpaid after 7 days (test_hourlyOneWeiTopUpsSlowTheStream).

  Proof: test/scratch/Proof_36e4e9a01ffd.t.sol fails on this code with 'the day's share vanished back into the stream: 0 < 714285714285734400'.

• 2.lowctoSetRecipient executed inside an outside PoolManager unlock skips the hook flush silently, so creator fees pending in PadHook go to the new recipient (R1-A4-8 fix incomplete)launchpad/contracts/src/CreatorVault.sol:174

          if (hook.code.length != 0) IFeeFlusher(hook).flush(coin); // credits this vault before the switch

  The R1-A4-8 fix relies on PadHook.flush(coin) crediting the vault before the recipient switch, so creator fees still pending in the hook (from outside-router swaps since the last flush) are paid to the old recipient.

  Since D-78 PadHook.flush returns without doing anything whenever the PoolManager is already unlocked (PadHook.sol:341), and neither ctoSetRecipient nor CTOModule.execute (permissionless during the 3-day window, no unlock check, CTOModule.sol:294) refuses to run inside an outside unlock.

  So the party that benefits from the takeover, or anyone, can call execute(coin) from its own poolManager.unlock callback at the first second of the window: the vault balance is paid to the old recipient, the flush is a no-op, and the creator share of every outside-router swap since the last flush is credited to the new recipient on the next flush. The old recipient cannot defend reliably because the executor chooses the timing.

  Loss is bounded by the creator share (0.5% plus the creator's part of the coin tax) of outside-router volume since the last router trade on that coin, so Low like the original finding; the guarantee the fix states in the code comment ('including the ones still pending in the hook') does not hold.

  Fix: in ctoSetRecipient revert while IHolderCoin(coin).poolManager().isUnlocked() (the vault already reads it that way in _releaseToHolders), or make CTOModule.execute refuse an unlocked PoolManager; alternatively make flush revert instead of returning when called by the vault inside a foreign unlock. Merges specialist findings 7668d404, bd91afb2 and a739c556; reproduced here through the real CTOModule (council proposal) rather than a stub.

  whole finding

  JudgeTest.test_realCtoExecuteInsideUnlockSkipsHookFlush (test/scratch/Judge.t.sol): launch a no-tax coin, fill the curve, vault.claim(coin) so the vault balance is 0; the council proposes a takeover to a contract recipient (proposeByCouncil) and 7 days pass.

  An outside router (PoolSwapTest) buys the coin with 1,000 IMD: hook.pending(coin).creator == 5e18, nothing flushed.

  A contract calls poolManager.unlock and inside unlockCallback calls cto.execute(coin).

  Expected (R1-A4-8, test_cto_hookPendingFeesGoToOldRecipient): the creator receives the 5 IMD pending in the hook before the switch.

  Actual: execute succeeds, recipientOf(coin) == community, hook.pending(coin).creator is still 5e18, the creator's balance is unchanged; after hook.flush(coin) and vault.claim(coin) the community recipient holds 5e18 and the creator never gets it.

  The same test passes once ctoSetRecipient (or execute) reverts while the PoolManager is unlocked.

• 3.lowThe first buy of a holder-tax coin (usually the creator's dev buy) gets its own holder tax back: the tax is parked because no holder is eligible yet and is credited at the next trade to the first buyelaunchpad/contracts/src/PadToken.sol:84

          if (amount == 0 || eligibleSupply < MIN_ELIGIBLE) return;

  BondingCurve.buy routes the holder share to the token and calls distribute() before the buyer receives tokens (BondingCurve.sol:227-231) so that 'a buyer never earns from their own buy'. But distribute() returns early while eligibleSupply < MIN_ELIGIBLE (1e18), which is always the case for the first buy of a coin (and again whenever every holder has sold back below one token in total).

  That buy's holder tax stays parked on the token (balance - accountedImd) and is credited at the next distribute(), which runs inside the next trade's _routeFees before that trade's buyer receives tokens: at that moment the first buyer is the only eligible holder and is credited the whole parked amount.

  With a dev buy at launch (exempt from snipe tax and max-buy, D-28) the creator therefore recovers 100% of the holder tax on an arbitrarily large dev buy, while every later buyer's holder tax goes to others. Nobody else loses funds and the amount is the first buyer's own tax, so Low: an asymmetry between the first buy and every other buy that contradicts the ordering the code comment promises.

  Fix preserving the design: when the holder part would be parked (eligible supply below the minimum), have BondingCurve.buy send that trade's holder part to the growth fund or the creator vault instead of the token, or let PadToken hold it in a bucket that is only credited after the buyer's own transfer; or document the behaviour. Merges specialist findings 8584adff and 79e1a878.

  JudgeTest.test_firstBuyHolderTaxReturnsToFirstBuyer (test/scratch/Judge.t.sol): launch a coin with CoinFees(300, 0, 10_000, 0) (3% holder tax) through PadRouter.launchWith with devBuy = true and 1,001 IMD (1 IMD launch fee + 1,000 IMD dev buy).

  Right after launch imd.balanceOf(coin) == 30e18 and PadToken.withdrawableDividendOf(creator) == 0 (parked, eligibleSupply was 0 at distribute).

  One hour later alice buys 1 IMD.

  Expected: the creator earns nothing from its own buy; alice and later holders share the holder tax of trades made after they bought.

  Actual: the creator's PadToken.claim() pays 30029999999999999999 wei (its own 30 IMD dev-buy tax plus alice's 0.03 IMD, minus 1 wei rounding).

  The same happens without a dev buy for whoever buys first (specialist 79e1a878: alice buys 100 IMD, bob buys 1 IMD, withdrawableDividendOf(alice) == 3029999999999999999).

• 4.infoPadHook._seed sweeps the hook's entire IMD and coin balances at every graduation, not only that graduation's rounding dustlaunchpad/contracts/src/PadHook.sol:194

          uint256 imdDust = SafeTransferLib.balanceOf(imd, address(this));

  The 'rounding dust' sweep reads the hook's whole balance of IMD (sent to the growth fund) and of the graduating coin (burned). Any IMD that reaches the hook by other means (a user transfer by mistake, a creator who set its fee recipient to the hook and claimed) is moved to the growth fund at the next graduation of any coin instead of being recoverable, and any of the coin's tokens sent to the hook before its graduation are burned.

  No protocol or third-party funds are at risk: the hook never legitimately holds IMD outside _flush (take and forward in one call, inside the hook's own unlock where no outside code runs) and _seed; the only loser is whoever sent tokens to the hook. Consider computing the dust from the amounts actually paid (amount0 / amount1 minus the settled delta) rather than from balances, or documenting that the hook address is a sink. Specialist finding 887ae4da, reproduced.

  whole finding

  JudgeTest.test_seedSweepsStrayHookImd (test/scratch/Judge.t.sol): alice transfers 1e18 IMD to address(hook); a no-tax coin is launched and its curve filled.

  Expected: the 1e18 IMD remains on the hook or is retrievable.

  Actual: after graduation imd.balanceOf(hook) == 0 and the growth fund's balance rose by more than 1e18 + the graduation fee (TARGET * 99 / 10_000).

• 5.infoARCHITECTURE-v1 §4.3 lists the coin snipe tax as a FeeSplitter inflow; the code, GrowthFund's header and HANDOFF send it to the GrowthFundlaunchpad/ARCHITECTURE-v1.md:157

  Inflows: protocol fee (curve and hook), launch fees, snipe tax. Graduation fees go straight to GrowthFund. `distribute()` is permissionless.

  BondingCurve.buy sends the snipe tax straight to config.growthFund() (BondingCurve.sol:229: if (snipe != 0) imd.safeTransfer(config.growthFund(), snipe);); the test test_snipeTax_decaysAndGoesToGrowth, GrowthFund.sol:9 ('graduation fees and snipe taxes') and HANDOFF agree. ARCHITECTURE-v1.md §4.3 instead lists the snipe tax among the FeeSplitter's inflows, which would give stakers 40%, workers 25%, growth 20% and the treasury 15% of it.

  DECISIONS names the destination only for the $PONDPAD sale's snipe tax (D-35, growth), not for coins. Documentation mismatch only; whichever is intended should be stated once in ARCHITECTURE and DECISIONS. Specialist finding 3237c66d, verified against the code and the docs.

  Launch a coin and buy 100 IMD inside the snipe window (test_snipeTax_decaysAndGoesToGrowth in test/PondPad.t.sol): the growth fund's IMD balance rises by the full snipe tax and the FeeSplitter receives only the 1% protocol part.

  Expected per ARCHITECTURE-v1.md line 157: the snipe tax reaches the FeeSplitter.

  Actual: it reaches the GrowthFund.

   Result: no Critical, High or Medium found in this area. Four findings written to .imd-findings.json: three Low, one Info.

   • Low, CreatorVault.sol:174 (proof attached). The R1-A4-8 fix is bypassable. A takeover executed from inside an outside PoolManager unlock makes ctoSetRecipient call PadHook.flush, which silently returns while unlocked. Creator fees still pending in the hook from outside-router swaps then go to the new recipient instead of the old one. The proof fails on the current code and tolerates a revert-while-unlocked fix.
   • Low, CreatorVault.sol:139 (proof attached). fundHolders with 1 wei from inside an outside unlock releases nothing but still resets the stream clock, so the day's share that was due is dropped. Anyone can repeat this to delay a holder-routed coin's dividends. No funds are lost.
   • Low, PadToken.sol:84. The first buy of a holder-tax coin, typically the creator's dev buy, finds no eligible holders. Its holder tax is parked and credited at the next trade to the first buyer alone, so the creator recovers 100% of the tax on an arbitrarily large dev buy.
   • Info, ARCHITECTURE-v1.md:157. The architecture lists the snipe tax as a FeeSplitter inflow. The code, HANDOFF and GrowthFund's header send it to the GrowthFund.

   What was checked and held. Invariants 1 through 9 of the threat model. Curve solvency and x·y ≥ k under random buy/sell sequences on one and on three coins sharing the curve's IMD balance, including completing buys inside the snipe window with full max-buy, a dev buy that completes the curve inside the launch transaction, and refunds. Graduation price equals E/R in both currency orderings across 512 fuzz runs. Hook accounting for exact-in and exact-out in both orderings: ERC-6909 claims always equal pending totals, fee is exactly the bps on the filled IMD, exact-out sell partial fills revert, flush leaves zero claims. Flash-borrowed pool tokens inside an unlock earn no dividends, even with IMD parked in the token. Lens pool quotes match real router trades exactly. Pool init, liquidity add and remove guards, hookData trust, integrator share only from the protocol fee, router leftover and ETH exactness, and permit handling were traced without finding a defect. Round 1 fixes R1-A1-1, A1-2, A1-4, A1-6, A1-8, A1-9, A4-1 and A4-4 are correct; R1-A4-8 is incomplete as above.

   Not done. No fork tests were run. The remaining open items from round 1 (R1-A1-3, A1-5, A1-7, A1-10) were not re-reported since no worse path was found.

   • lowR1-A4-8 fix is bypassable: a takeover executed inside an outside PoolManager unlock skips the hook flush, so creator fees pending in the hook go to the new recipientlaunchpad/contracts/src/CreatorVault.sol:174

     CreatorVault.ctoSetRecipient relies on PadHook.flush(coin) to move the creator fees still pending in the hook (from outside-router swaps since the last flush) into the vault before the recipient switch, so they are paid to the old recipient (audit R1-A4-8, marked fixed in 23549a8). But PadHook.flush returns silently while poolManager.isUnlocked() (PadHook.sol:341), and CTOModule.execute is permissionless with no unlock guard (CTOModule.sol:294).

     The takeover beneficiary, or anyone, can call execute(coin) from inside their own PoolManager unlock callback: ctoSetRecipient runs, the flush does nothing, the old recipient is paid only the vault balance, and every creator fee pending in the hook is flushed later to the new recipient.

     The R1-A4-8 guarantee ('fees accrued before the takeover are paid to the old recipient, including the ones still pending in the hook') therefore holds only when the caller does not choose the call context. Loss is bounded by the creator share of outside-router volume since the last flush, so Low, like the original finding.

     Fix: in ctoSetRecipient revert while IHolderCoin(coin).poolManager().isUnlocked() (or have CTOModule.execute refuse an unlocked PoolManager), so the flush can never be skipped. The attached proof passes with either.

     whole finding

     Graduated coin whose creator fees go to the creator.

     (1) Any wallet buys the coin with 100 IMD through a v4 router other than PadRouter (PoolSwapTest in the proof): hook.pending(coin).creator == 0.5e18 and the vault balance is unchanged.

     (2) A contract calls poolManager.unlock and, inside unlockCallback, executes an executable takeover to newRecipient (CTOModule.execute; the proof uses a stub with the same body, vault.ctoSetRecipient(coin, newRecipient), since the module has no unlock guard).

     Expected: the 0.5 IMD is flushed and paid to the old recipient before the switch.

     Actual: hook.pending(coin).creator is still 0.5e18 after the switch; the next hook.flush(coin) + vault.claim(coin) pays 0.5 IMD to newRecipient and the old recipient gets 0.

     Proof: test/scratch/ProofCtoFlush.t.sol (fails now: 'old recipient must get the pre-takeover fees: 0 != 500000000000000000').

   • lowCreatorVault.fundHolders called inside an outside PoolManager unlock restarts the holder stream clock without releasing, dropping the share that was duelaunchpad/contracts/src/CreatorVault.sol:139

     _fundHolders first calls _releaseToHolders, which returns 0 without touching the stream while the PoolManager is unlocked (line 148), and then unconditionally sets lastReleaseAt = block.timestamp and recomputes ratePerSecond from the new remainder. fundHolders is permissionless for any registered coin and accepts 1 wei, so anyone can, from inside their own unlock callback, reset a coin's holder stream: the up-to-one-day share that was releasable is not paid and the schedule restarts from now.

     Repeating this shortly before each keeper release keeps releaseToHolders paying nothing or close to it for as long as the attacker keeps it up (Robinhood blocks are sub-second and cheap). No IMD is lost (remaining is preserved) and the attacker pays gas plus 1 wei per call, so this is griefing that delays holder dividends, not theft; it also silently weakens the D-78 promise that a stream pays out over about 7 days.

     The same path exists through claim(coin) when the recipient is the coin, and through SwarmBudget.sweepToHolders, but those need a non-zero balance.

     Fix: in _fundHolders skip the lastReleaseAt / rate reset when _releaseToHolders could not release because the PoolManager is unlocked (return a flag from _releaseToHolders), or revert fundHolders / claim-to-coin while unlocked. The attached proof passes with either.

     whole finding

     Graduated coin whose recipient is the coin itself; vault.fundHolders(coin, 700e18) at t0.

     At t0 + 1 day, vault.releasableToHolders(coin) is about 100e18 (one day's share).

     A contract then calls poolManager.unlock and, inside unlockCallback, vault.fundHolders(coin, 1).

     Expected: the due share is released first or the call is refused while unlocked.

     Actual: releasableToHolders(coin) == 0 right after, releaseToHolders(coin) returns 0 and sends nothing to the coin, holderStreamOf(coin).remaining == 700e18 + 1 and lastReleaseAt == now.

     Proof: test/scratch/ProofStreamReset.t.sol (fails now: 'the day's share must not be dropped by a 1 wei top-up: 0 < 100000000000000051200').

   • lowThe first buy of a holder-tax coin (usually the creator's dev buy) pays its holder tax to itself: the tax is parked because no holder is eligible yet and is credited at the next trade to the first buylaunchpad/contracts/src/PadToken.sol:84

     BondingCurve.buy routes fees before the buyer receives tokens (BondingCurve.sol:228), so on the very first buy of a coin PadToken.distribute() sees eligibleSupply == 0 < MIN_ELIGIBLE and returns, leaving the holder-tax IMD parked in the token (accountedImd unchanged). The next call to distribute(), which happens inside the next trade's _routeFees before that trade's buyer receives tokens, credits the whole parked amount to the holders at that moment: only the first buyer.

     With a dev buy at launch (exempt from snipe tax and max-buy, D-28), the creator thus recovers 100% of the holder tax on an arbitrarily large dev buy, while every later buyer's holder tax goes to others. Nobody else loses funds and the amount is the creator's own tax, so Low: an asymmetry between the first buy and every other buy, and a mild inconsistency with the 'buyer never earns from their own buy' comment at BondingCurve.sol:227.

     A fix that preserves the design: in distribute(), when eligibleSupply < MIN_ELIGIBLE, do nothing (as now) but have BondingCurve.buy send that trade's holder part to the growth fund or the creator vault instead of the token when the coin has no eligible holders yet, or document the behaviour.

     whole finding

     Launch a coin with CoinFees(300, 0, 10_000, 0) (3% holder tax) through PadRouter.launchWith with devBuy = true and 1,000 IMD: imd.balanceOf(coin) == 30e18 and withdrawableDividendOf(creator) == 0 right after launch.

     One hour later alice buys 1 IMD.

     Expected: alice (and later holders) share the holder tax of trades made after they bought; the dev buy's 30 IMD tax should not return to the creator.

     Actual: the creator's claim() pays 30.03 IMD (its own 30 IMD dev-buy tax plus alice's 0.03 IMD).

     Scratch test test_firstBuyHolderTaxIsCreditedBackToTheFirstBuyer in test/scratch/Audit3.t.sol reproduces this (it asserts the actual behaviour and passes).

   • infoARCHITECTURE §4.3 says the snipe tax flows into the FeeSplitter; the code (and GrowthFund's header, HANDOFF) send it to the GrowthFundlaunchpad/ARCHITECTURE-v1.md:157

     BondingCurve.buy sends the snipe tax straight to config.growthFund() (BondingCurve.sol:229: if (snipe != 0) imd.safeTransfer(config.growthFund(), snipe);), and the test test_snipeTax_decaysAndGoesToGrowth, GrowthFund.sol:9 and HANDOFF agree. ARCHITECTURE-v1.md §4.3 lists the snipe tax among the FeeSplitter's inflows (split 40/25/20/15, so stakers would get 40% of it).

     Documentation mismatch only; whichever is intended should be stated once (DECISIONS has no entry naming the coin snipe tax destination; D-35 does for the sale).

     Launch a coin and buy 100 IMD inside the snipe window: the growth fund balance rises by the full snipe tax and the FeeSplitter receives only the 1% protocol part (test_snipeTax_decaysAndGoesToGrowth).

     Expected per §4.3: the snipe tax reaches the FeeSplitter.

     Actual: it reaches GrowthFund.

3. Audit economicsAgent #1812found 1 medium, 1 low

   Review complete. The findings file is written at the repository root and no source or config files were changed; only launchpad/contracts/test/scratch/ holds my throwaway tests.

   Outcome: 1 Medium, 1 Low, no High or Critical in area A1.

   Medium: CreatorVault holder stream clock can be wiped by anyone inside an outside PoolManager unlock (launchpad/contracts/src/CreatorVault.sol:139). The _fundHolders path first calls the release, which silently returns while the PoolManager is unlocked, then unconditionally sets lastReleaseAt to now and re-spreads the remainder over 7 days. An attacker's contract unlocks the PoolManager and, in the callback, calls the permissionless claim(coin) on a holder-routed coin (or fundHolders(coin, 1) or SwarmBudget.sweepToHolders). The day's accrued share vanishes and the stream never pays while the attacker repeats this at gas cost. Foundry proof included: it fails on the current code with 0 < 714285714285734400 and is written to pass under either fix (skip or revert when unlocked, or only move the clock after a real release).

   Low: the first buyer gets its own holder tax back (launchpad/contracts/src/PadToken.sol:84). distribute() returns early below one eligible token, so the first buy's holder tax is parked and credited at the next trade, when the first buyer is the only holder. With a 3% holder tax, alice recovered 3 of 3 IMD. No third party loses; it contradicts the curve's documented ordering.

   Checked and found sound (invariants 1 to 9 of the threat model):

   • Curve math: 512-run stateful fuzz over buy/sell sequences, snipe window, completing buy and refund. raised == x − x0, curve balance covers every coin, k never shrinks, pool opens at E/R within 1e-12 in both currency orderings.
   • Graduation: only the hook can initialize or add liquidity, removals always revert, inline graduation under the locked check, 1% fee and matching reserve burn keep the price continuous.
   • PadHook v4 accounting: traced the vendored Hooks.beforeSwap/afterSwap delta signs and tested exact-out buy, exact-out sell and exact-in sell through an outside router in both orderings. Fee is exactly the coin's bps on the gross IMD, pending always equals the hook's ERC-6909 claims, flush leaves zero claims, exact-out partial fill reverts.
   • PadToken dividends: corrections make flash-borrowed or in-unlock tokens earn nothing; distribute runs only when locked or from the hook's own flush.
   • PaymentSwapper/PadRouter: ETH and IMD leftovers are zero after a completing buy paid in ETH and a curve sell paid out in ETH; reentrancy through ETH receivers is blocked by the curve's locked check and the router's guard.
   • Integrator share, FeeSplitter sums, SwarmBudget reservations, PadLens quotes against the real hook maths, deployer one-time setters (all consumed in Deploy.s.sol).

   Round-1 fixes in this area re-verified: R1-A1-1, A1-2, A1-4, A1-6, A1-8, A1-9 are correct and complete. R1-A1-6's fix (claim to the coin feeds the stream) is what the new Medium rides on.

   Not covered: fork tests against mainnet IMD/USDG were not run (no network use in the verification profile); the invariant/exact-out gaps noted as open in R1-A1-10 are now exercised by my scratch tests but those are not kept.

   • mediumCreatorVault holder stream: funding inside an outside PoolManager unlock wipes the accrued share and restarts the clock (permissionless, gas-only griefing of holder dividends)launchpad/contracts/src/CreatorVault.sol:139

     _fundHolders first calls _releaseToHolders, which returns 0 without touching state while the PoolManager is unlocked (CreatorVault.sol:148), and then unconditionally sets st.lastReleaseAt = block.timestamp and re-spreads remaining over 7 days.

     So any funding call that runs inside an outside unlock deletes the time accrued since the last release: the share that was due (up to one day's worth, ratePerSecond * elapsed) is never paid for that period and the whole remainder is stretched over a fresh 7 days.

     Three permissionless entry points reach _fundHolders: CreatorVault.claim(coin) when the coin's recipient is the coin itself (any non-zero balanceOf[coin], which every router trade refills through the hook flush), CreatorVault.fundHolders(coin, 1 wei), and SwarmBudget.sweepToHolders(coin). An attacker unlocks the PoolManager from its own contract and calls one of them in unlockCallback, repeatedly (every few minutes, or ahead of each keeper release).

     Holders of every holder-routed / CTO'd coin then receive at most rate * (time since the last reset) per release instead of the ~7-day stream D-78 promises, for as long as the attacker pays gas; the IMD stays locked in the vault's stream (not stolen). This is the part of invariant 6 (holder lumps released through the stream over ~7 days) that was checked.

     Note also that even outside an unlock every re-fund re-spreads the remainder over 7 days, so a stream that is re-funded daily (legit claims, or 1-wei fundHolders calls) decays geometrically: with daily re-funds 34% of a lump is still unreleased after 7 days; that part is the documented design, the in-unlock clock wipe is not.

     Fix: in _fundHolders, move lastReleaseAt only when _releaseToHolders actually released (or carry the skipped amount in an accrued bucket), or make the funding paths revert / return while isUnlocked(), as the curve does for trades.

     Launch a coin (no tax); creator calls vault.setRecipient(coin, coin); alice buys 1,000 IMD via PadRouter (0.5% creator fee = 5 IMD in the vault); anyone calls vault.claim(coin) -> holder stream remaining = 5e18, rate = ceil(5e18 / 7 days).

     Warp +1 day: vault.releasableToHolders(coin) = 714285714285734400 (one day's share).

     Alice buys 10 IMD (0.05 IMD lands in the vault).

     Attacker contract calls poolManager.unlock(...) and inside unlockCallback calls vault.claim(coin).

     Expected: the 0.714 IMD is released to holders or still releasable afterwards.

     Actual: PadToken.totalDividendsDistributed() is unchanged and vault.releasableToHolders(coin) == 0 (assert 0 < 714285714285734400 fails); lastReleaseAt was moved to now and the remainder (5.05 IMD) re-spread over 7 days.

     Repeating the call keeps the stream at zero release indefinitely.

     whole proof

   • lowThe first buyer of a coin (eligible supply below 1 token) is paid back its own holder tax at the next distribute(), contradicting the curve's 'a buyer never earns from their own buy' orderinglaunchpad/contracts/src/PadToken.sol:84

     BondingCurve.buy routes the holder share to the token and calls distribute() before the buyer receives tokens (BondingCurve.sol:227-231) so that a buyer never shares in its own holder tax. But distribute() returns early while eligibleSupply < MIN_ELIGIBLE (1e18), which is always the case for the first buy of a coin launched without a dev buy (and again whenever every holder has sold back below one token).

     The holder tax of that buy is parked on the token (balance - accountedImd) and is credited at the next distribute(), i.e. inside the next trade's _routeFees, at which point the first buyer is the only (or dominant) eligible holder and receives its own tax back.

     Effect: the first buyer pays no holder tax in practice (up to 3% of its buy); nobody else loses, so the impact is a documented-ordering violation with a small, bounded value.

     Fix: credit the parked amount to a pendingDistribution that is only released once eligible supply exists and the buyer has been excluded (e.g. distribute after the transfer when eligibleSupply was below the minimum, or send the parked part to the creator vault / growth fund), or document the behaviour.

     whole finding

     Launch a coin with CoinFees(300, 0, 10_000, 0) (3% holder tax), no dev buy; warp past the snipe/max-buy windows.

     Alice buys 100 IMD through PadRouter: holder tax 3e18 IMD is transferred to the token, distribute() returns early (eligibleSupply 0), imd.balanceOf(coin) - accountedImd() == 3e18, withdrawableDividendOf(alice) == 0.

     Bob buys 1 IMD: distribute() now credits 3.03e18 to holders and withdrawableDividendOf(alice) == 3029999999999999999, i.e. alice recovers her whole 3 IMD holder tax.

     Expected (per the code comment at BondingCurve.sol:227): alice earns nothing from her own buy.

4. Audit flowAgent #1294found 2 low, 1 info

   The review is complete. The findings file is written and only scratch tests were added to the tree.

   Result: no Critical, High or Medium in area A1. The findings file holds two Lows and one Info, each with a concrete reproduction. Two carry a Foundry test under test/scratch/.

   Findings

   • Low, CreatorVault.sol:174. The R1-A4-8 fix is incomplete. ctoSetRecipient relies on PadHook.flush, which silently returns inside any unlock, and CTOModule.execute is permissionless with no unlock check. Running execute from inside one's own PoolManager unlock skips the flush, so creator fees pending in the hook go to the new recipient instead of the old one. Bounded by outside-router volume since the last flush. Test confirms the path.
   • Low, CreatorVault.sol:138. fundHolders(coin, 1 wei) is permissionless and restarts the 7-day stream clock on the whole remainder. Hourly 1-wei calls leave 2.57 of 7 IMD unpaid after 7 days where the honest timeline pays everything. Delay only, no loss.
   • Info, PadHook.sol:192. The graduation dust sweep moves the hook's entire IMD and coin balances, so anything sent to the hook by mistake is burned or sent to growth at the next graduation.

   What I verified and found sound

   • Invariants 1, 2, 3, 4, 6, 7, 8, 9 and 15 from the threat model were checked against the code.
   • Curve solvency and graduation: a stateful fuzz over random buy and sell sequences, targets of 1,000 to 10,000 IMD, graduation fees of 0 to 2%, snipe tax up to 90% and both token orderings. The curve's IMD always equals the sum raised, graduation never reverts, and the pool opens at E/R within rounding. The completing buy's net raise lands within 2 wei of the target.
   • PadHook accounting: exact-in and exact-out, buys and sells, both currency orderings, through an outside router. The fee equals the coin's bps on the filled IMD in every case, ERC-6909 claims always equal pending totals, flush drains both, and an exact-out sell beyond the pool's IMD reverts with PartialFill.
   • Unlock guards: curve trades, holder-stream releases and hook flushes all refuse to act inside an outside unlock, and nested unlocks are impossible, so the R1-A1-1 fix opens no DoS path.
   • Router and PaymentSwapper: ETH is fully settled or the unlock reverts, partial fills on payment routes revert rather than strand funds, the shared reentrancy guard blocks re-entry from ETH receivers, and hook data is trusted only when the sender is the router.

   Earlier fixes rechecked: R1-A1-1, A1-2, A1-4, A1-6, A1-8, A1-9, A4-1, A4-4 and A4-11 are correct and complete. R1-A4-8 is the one with a gap, reported above.

   Not covered: Fork tests against the live Robinhood PoolManager were not run (no network in the verifier). Slither and other static tools were not available.

   • lowctoSetRecipient executed inside an outside PoolManager unlock skips the hook flush, so the old recipient loses the creator fees pending in PadHook (R1-A4-8 fix incomplete)launchpad/contracts/src/CreatorVault.sol:174

     R1-A4-8 was fixed by having CreatorVault.ctoSetRecipient call PadHook.flush(coin) before paying the old recipient, so creator fees still pending in the hook (from outside-router swaps since the last flush) go to the old recipient. But PadHook.flush (src/PadHook.sol:340-343) returns silently whenever the PoolManager is already unlocked, and CTOModule.execute (src/CTOModule.sol:294-304) is permissionless with no unlock check.

     Anyone can therefore run execute() from inside their own PoolManager.unlock callback: flush() is a no-op, the vault pays the old recipient only its own balanceOf[coin], the recipient switches, and the fees still pending in the hook are credited to the new recipient at the next flush. The timing is fully under the executor's control (first transaction at executableAt), so the old recipient cannot defend by flushing first.

     Loss is bounded by the creator share of outside-router volume since the last router trade on that coin, which is why this is Low rather than Medium.

     Fix: in ctoSetRecipient revert (or in CTOModule.execute refuse) while poolManager.isUnlocked(), e.g. if (IPoolManager(pm).isUnlocked()) revert PoolManagerUnlocked(); before the flush, mirroring BondingCurve._checkLocked; alternatively make PadHook.flush revert instead of returning when called by the CreatorVault inside a foreign unlock.

     whole finding

     State: graduated coin, no tax, creator = recipient.

     An outside router (PoolSwapTest) buys 100 IMD of the coin: hook.pending(coin).creator = 0.5e18, not flushed. vault.claim(coin) so balanceOf[coin] = 0.

     A contract that is the vault's ctoModule (standing in for CTOModule.execute, which anyone can call) calls poolManager.unlock and, in its callback, vault.ctoSetRecipient(coin, community).

     Expected (R1-A4-8): creator receives the 0.5 IMD pending in the hook before the switch.

     Actual: hook.pending(coin).creator stays 0.5e18, creator receives 0; after hook.flush(coin) and vault.claim(coin) the new recipient holds 0.5e18.

     Proof: test/scratch/CtoUnlock.t.sol test_ctoSetRecipient_insideOutsideUnlock_skipsHookFlush (passes on current code, demonstrating the path).

   • lowAnyone can slow a coin's holder stream indefinitely: fundHolders(coin, 1 wei) re-spreads the whole remainder over a fresh 7 days and restarts the clocklaunchpad/contracts/src/CreatorVault.sol:138

     CreatorVault.fundHolders is permissionless for any registered coin and accepts any non-zero amount. _fundHolders releases what is due, then recomputes ratePerSecond = ceil(remaining / 7 days) and sets lastReleaseAt = now. A griefer who adds 1 wei every hour turns the intended linear 7-day payout into an exponential decay with a 7-day time constant: after 7 days ~37% of the lump is still unpaid, after 21 days ~5%.

     When fundHolders is called from inside an outside PoolManager unlock the preceding _releaseToHolders releases nothing (D-78 guard) but lastReleaseAt is still reset, so the accrued (up to one day) elapsed time is discarded as well. No IMD is lost (remaining is never reduced without a transfer), so this is a bounded delay/griefing, Low.

     Fix: only reset lastReleaseAt / ratePerSecond when the added amount is material relative to remaining (e.g. keep the existing rate and only add the new amount's own rate: rate += ceil(amount / 7 days)), or restrict fundHolders to SwarmBudget and the vault itself, or require a minimum amount.

     whole finding

     Coin with recipient = coin; vault.fundHolders(coin, 7e18) (1 IMD/day stream).

     Honest timeline: releaseToHolders once a day for 7 days -> holderStreamOf(coin).remaining == 0.

     Griefer timeline from the same state: bob calls vault.fundHolders(coin, 1) every hour for 7 days (168 calls, 168 wei) -> holderStreamOf(coin).remaining == 2567472868092292168 (2.57 of 7 IMD still unpaid after 7 days; expected 0).

   • infoPadHook._seed sweeps the hook's entire IMD and coin balances, not only this graduation's dustlaunchpad/contracts/src/PadHook.sol:192

     The 'rounding dust' sweep reads the hook's whole balance of IMD and of the graduating coin. Any IMD or coin tokens that reach the hook by other means (a user transfer by mistake, a creator who set feeRecipient = hook and claimed) are moved to the growth fund / burned at the next graduation of any coin instead of being recoverable.

     No protocol or third-party funds are at risk because the hook never legitimately holds IMD outside _flush (which takes and forwards in one call) and _seed; the only loser is whoever sent tokens to the hook. Consider computing the dust from the amounts actually paid (amount0/amount1 minus -delta) rather than from balances, or documenting that the hook address is a sink.

     Transfer 1e18 IMD from alice to address(hook).

     Launch and fill a coin's curve.

     Expected: 1e18 IMD remains on the hook (or is retrievable).

     Actual: growth fund balance increases by 1e18 plus the graduation fee and dust; hook IMD balance is 0.

5. Audit mathAgent #1401found 1 medium, 1 low

   The review is complete. The findings file is valid, both snippets match the tree, and the working tree holds only the allowed scratch tests.

   Outcome: two findings, no Critical or High. The coin trading core's math held up under every probe I ran. The defects are both in CreatorVault's D-78 holder stream, the fix added in round 1.

   Findings written to .imd-findings.json:

   • Medium, CreatorVault.sol:139. Anyone can stall a coin's holder stream for the price of gas. Funding the stream with 1 wei from inside an outside PoolManager unlock skips the release (by design) but still resets the stream clock, so the day's share that was due folds back into the remainder. Repeated hourly against a daily keeper, holders received about 4% of a 5 IMD stream over its full 7 days instead of all of it. Carries a self-contained proof that fails now and passes with a one-line guard.
   • Low, CreatorVault.sol:174. The R1-A4-8 fix is incomplete. Executing a takeover from inside an outside unlock makes the hook flush a silent no-op, so creator fees pending in PadHook go to the new recipient instead of the ousted creator. Bounded by one flush interval of outside-router volume.

   What I verified and found sound (invariants 1 to 9 and 15 of the threat model):

   • Graduation fuzzed over the full target range, every graduation fee, both currency orderings and random trade histories: the pool always opens at the curve's final price, the hook holds no dust, and the curve ends empty.
   • Multi-coin sell-everything stays exactly solvent; the completing buy lands at the ceiling of k/V with the correct refund.
   • Exact-out buys and sells through an outside router in both orderings charge exactly the fee on the filled IMD, and claims flush to zero.
   • PadLens quotes equal real trade outputs on both the curve and the pool across fuzzed sizes.
   • Flash-borrowed pool tokens capture nothing through distribute, flush, releaseToHolders, graduate or claim.
   • All round-1 fixes marked fixed for this area are in place, apart from the incomplete R1-A4-8 above.

   Scratch tests remain under launchpad/contracts/test/scratch/, which the task designates as disposable. No repository file was changed.

   bundlenone

   • mediumCreatorVault holder stream can be stalled by anyone: fundHolders / claim / sweepToHolders inside an outside PoolManager unlock reset the stream clock without releasing the due sharelaunchpad/contracts/src/CreatorVault.sol:139

     _fundHolders first calls _releaseToHolders, then unconditionally overwrites lastReleaseAt with block.timestamp and re-rates the whole remainder over 7 days. _releaseToHolders deliberately releases nothing while the PoolManager is unlocked by an outside caller (line 148, D-78), but _fundHolders does not know the release was skipped: the day's share that was due is folded back into remaining and the clock restarts. fundHolders(coin, amount) is permissionless for any registered coin with any amount >= 1 wei, and claim(coin) / SwarmBudget.sweepToHolders(coin) reach the same code.

     An attacker who wraps fundHolders(coin, 1) in their own poolManager.unlock therefore pushes lastReleaseAt forward at the cost of gas plus 1 wei, every time, and the permissionless releaseToHolders (keeper, daily) then finds elapsed close to zero.

     The holder stream is the only path by which holder-routed creator fees and swept swarm budgets reach holders (R1-A4-1 fix), so this is a cheap, repeatable denial of that path: funds are not lost but never arrive while the attacker keeps calling. The honest path outside an unlock is unaffected (it releases first).

     Seam: boundary (unlock early-return) x invariant (stream pays remaining over <= 7 days).

     Fix: in _fundHolders, keep lastReleaseAt (and the old rate for the elapsed part) when _releaseToHolders skipped a non-zero due amount, e.g. revert fundHolders / the stream funding while poolManager().isUnlocked(), or accumulate the skipped amount in a due field that the next release pays regardless of elapsed.

     whole finding

     Setup (test/scratch/Stream.t.sol::test_streamStalledByOneWeiInsideUnlock): coin with 1.5% base fee, alice buys 1,000 IMD on the curve -> 5 IMD creator fee in the vault; creator calls setRecipient(coin, coin); anyone calls claim(coin) -> stream remaining = 5e18, rate = 8267195767196 wei/s, lastReleaseAt = T.

     Warp T + 1 day: releasableToHolders(coin) = 714285714285714 wei (one day's share, ~5e18/7).

     Attacker contract: approve 1 wei IMD, poolManager.unlock(...), inside the callback vault.fundHolders(coin, 1).

     Expected: either the due day's share is released first or the call is refused.

     Actual: remaining = 5e18 + 1, lastReleaseAt = T + 1 day, releasableToHolders(coin) = 0, PadToken.totalDividendsDistributed() = 0.

     Repeating the 1-wei unlock call every hour while the keeper calls releaseToHolders once a day pays holders 204649783459837200 wei (~0.2 IMD, 4%) over the full 7-day period instead of 5 IMD (100%).

     The same sequence outside an unlock (test_streamHonestFundReleasesFirst) pays the day's share first.

   • lowctoSetRecipient executed inside an outside PoolManager unlock skips the hook flush silently, so creator fees pending in PadHook go to the new recipient (R1-A4-8 fix incomplete)launchpad/contracts/src/CreatorVault.sol:174

     The R1-A4-8 fix relies on PadHook.flush(coin) crediting the vault before the recipient switch.

     Since D-78 flush returns without doing anything whenever the PoolManager is unlocked (PadHook.sol:341), and ctoSetRecipient neither checks that nor requires the flush to have happened. CTOModule.execute(coin) is permissionless during the 3-day window and has no unlock check, so anyone (in practice the party that benefits from the takeover) can execute it from inside their own poolManager.unlock callback: the vault balance accrued on the curve is paid to the old recipient, but the creator share of every outside-router swap since the last flush stays pending in the hook and is credited to the new recipient on the next flush.

     The amount is bounded by 0.5% (plus creator tax share) of outside-router volume since the last flush, so the loss to the ousted creator is small; the invariant the fix states ("fees accrued before the takeover are paid to the old recipient, including those pending in the hook") is broken.

     Fix: in ctoSetRecipient revert when IPoolManager(...).isUnlocked() (the vault can read it through the coin as _releaseToHolders does), or make flush revert instead of returning when called by the vault inside an unlock.

     whole finding

     test/scratch/Stream.t.sol::test_ctoInsideUnlockSkipsFlush (CTO module = a contract that calls ctoSetRecipient from its unlockCallback): graduate a no-tax coin; an outside router (PoolSwapTest) buys with 1,000 IMD -> hook.pending(coin).creator = 5e18 and nothing flushed.

     Execute the takeover to community from inside poolManager.unlock.

     Expected (R1-A4-8): the creator receives the vault balance plus the 5 IMD pending in the hook.

     Actual: the creator receives only the vault balance (10456852791878172588 wei from the curve phase); hook.pending(coin).creator is still 5e18 after the switch; after hook.flush(coin) and vault.claim(coin) the 5 IMD are paid to community, the creator never gets them.

6. Audit judgeAgent #729found 1 medium, 2 low, 2 info

   The review is complete. The findings file is at the repository root with five findings, and no source or configuration file was changed.

   Verdict for area A1. No open Critical or High. The eleven specialist reports collapse into five findings after reproduction and merging: one Medium, two Low, two Info.

   • Medium, CreatorVault holder stream stall. Funding a stream from inside an outside PoolManager unlock skips the release but still resets the stream clock, so a 1 wei top-up per day keeps holder payouts at zero for as long as the attacker pays gas. Funds are never lost. Four specialist reports merged into one. The attached proof fails on the current code and passes with a one-line guard, which I verified and then reverted.
   • Low, CTO takeover skips the hook flush. Executing a takeover from inside an outside unlock makes the flush a no-op, so creator fees pending in the hook go to the new recipient. I reproduced it through the real CTOModule via the council path, not a stub. Three reports merged.
   • Low, first buy gets its own holder tax back. The first buy's tax is parked because no holder is eligible yet, then credited to the first buyer at the next trade. A dev buy recovers its whole holder tax. Two reports merged.
   • Info, hook balance sweep at graduation moves any stray IMD on the hook to the growth fund.
   • Info, architecture doc lists the snipe tax as a FeeSplitter inflow while the code sends it to the GrowthFund.

   What I checked and found sound. Curve rounding and solvency, completing-buy refund, graduation price continuity and the 1% fee plus 1% burn, pool initialisation guards, liquidity add and remove guards, hook delta accounting for exact-in and exact-out in both currency orderings (my own scratch test, since the suite lacks exact-out coverage), partial-fill and zero-fill reverts, claims and flush accounting, hook data trust, dividend flash-borrow and same-block paths, router and swapper refunds, slippage, permit handling and reentrancy, integrator share bounds, FeeSplitter sums and PadLens quotes against real trades. Invariants 1 through 9 of the threat model hold on the code as reviewed. The full suite passes, 113 tests.

   Open for the owner. The Medium needs either a revert while the PoolManager is unlocked on the three stream-funding entry points, or a skipped-release flag that leaves the clock alone. The same guard on ctoSetRecipient closes the Low.

   • mediumAnyone can stall a coin's holder stream indefinitely: funding it inside an outside PoolManager unlock resets the stream clock without releasing the share that was duelaunchpad/contracts/src/CreatorVault.sol:134

     _fundHolders first calls _releaseToHolders, which deliberately releases nothing while an outside caller holds the PoolManager unlock (line 148, D-78), and then unconditionally sets lastReleaseAt = block.timestamp and re-spreads the whole remainder over a fresh 7 days. _fundHolders never learns that the release was skipped, so the time accrued since the last release (up to one day's share) is folded back into remaining and the clock restarts.

     Three permissionless entry points reach it: fundHolders(coin, amount) for any registered coin with any amount >= 1 wei, claim(coin) when the coin's recipient is the coin itself (any non-zero vault balance, refilled by every router trade through the hook flush), and SwarmBudget.sweepToHolders(coin); ctoSetRecipient reaches it too when the old recipient was the coin.

     An attacker who wraps fundHolders(coin, 1) in their own poolManager.unlock callback once per day (Robinhood blocks are sub-second and gas is cheap) keeps elapsed near zero for the keeper's daily releaseToHolders, so holder-routed creator fees and swept swarm budgets (the only path by which they reach holders since R1-A4-1) never arrive while the attacker keeps paying gas plus 1 wei per call.

     No IMD is lost: remaining is preserved and the stream resumes when the attacker stops. This is griefing that costs the attacker far less than it costs the holders, and a DoS of the D-78 payout path, hence Medium (two specialists rated it Medium, two Low).

     A related, milder variant needs no unlock: every top-up, honest or a 1-wei fundHolders every hour, re-rates the remainder over 7 days after releasing first, so the linear 7-day stream becomes an exponential decay (after 7 days of hourly 1-wei top-ups 2.567 of 7 IMD are still unpaid; 37%). That part follows from the documented 'reset the rate so the whole remainder pays out over HOLDER_STREAM_PERIOD from now' design; the in-unlock clock wipe does not.

     Fix: in _fundHolders, keep lastReleaseAt (and let the next release pay the skipped share) when _releaseToHolders could not release because the PoolManager was unlocked, e.g. have _releaseToHolders return a 'skipped' flag, or revert fundHolders / claim-to-coin / sweepToHolders while IHolderCoin(coin).poolManager().isUnlocked(), as the curve does for trades. The attached proof passes with either fix.

     Checked against THREAT-MODEL invariant 6 (lumps released through the holder stream over ~7 days); merges specialist findings 1ea59d2b, 36e4e9a0, 8a9210c7 and c6dc976e.

     whole finding

     Setup (Proof_36e4e9a01ffd / test/scratch/Judge.t.sol): launch a no-tax coin; alice buys 1,000 IMD through PadRouter (5 IMD creator fee in the vault); the creator calls vault.setRecipient(coin, coin); anyone calls vault.claim(coin): holderStreamOf(coin).remaining = 5e18, ratePerSecond = ceil(5e18 / 604800) = 8267195767196.

     Warp +1 day: vault.releasableToHolders(coin) = 714285714285734400 (one day's share).

     A contract approves 1 wei IMD to the vault, calls poolManager.unlock and inside unlockCallback calls vault.fundHolders(coin, 1).

     Expected: the day's share is released first or the call is refused while unlocked.

     Actual: PadToken.totalDividendsDistributed() stays 0, releasableToHolders(coin) == 0, remaining == 5e18 + 1, lastReleaseAt == now.

     Repeating the wrapped 1-wei call every hour for 7 days while releaseToHolders is called once a day pays holders exactly 0 (JudgeTest.test_stallInsideUnlockPaysNothing: paid == 0, remaining == 7e18 + 168).

     Without the unlock, hourly 1-wei top-ups leave 2567472868092292168 of 7e18 unpaid after 7 days (test_hourlyOneWeiTopUpsSlowTheStream).

     Proof: test/scratch/Proof_36e4e9a01ffd.t.sol fails on this code with 'the day's share vanished back into the stream: 0 < 714285714285734400'.

   • lowctoSetRecipient executed inside an outside PoolManager unlock skips the hook flush silently, so creator fees pending in PadHook go to the new recipient (R1-A4-8 fix incomplete)launchpad/contracts/src/CreatorVault.sol:174

     The R1-A4-8 fix relies on PadHook.flush(coin) crediting the vault before the recipient switch, so creator fees still pending in the hook (from outside-router swaps since the last flush) are paid to the old recipient.

     Since D-78 PadHook.flush returns without doing anything whenever the PoolManager is already unlocked (PadHook.sol:341), and neither ctoSetRecipient nor CTOModule.execute (permissionless during the 3-day window, no unlock check, CTOModule.sol:294) refuses to run inside an outside unlock.

     So the party that benefits from the takeover, or anyone, can call execute(coin) from its own poolManager.unlock callback at the first second of the window: the vault balance is paid to the old recipient, the flush is a no-op, and the creator share of every outside-router swap since the last flush is credited to the new recipient on the next flush. The old recipient cannot defend reliably because the executor chooses the timing.

     Loss is bounded by the creator share (0.5% plus the creator's part of the coin tax) of outside-router volume since the last router trade on that coin, so Low like the original finding; the guarantee the fix states in the code comment ('including the ones still pending in the hook') does not hold.

     Fix: in ctoSetRecipient revert while IHolderCoin(coin).poolManager().isUnlocked() (the vault already reads it that way in _releaseToHolders), or make CTOModule.execute refuse an unlocked PoolManager; alternatively make flush revert instead of returning when called by the vault inside a foreign unlock. Merges specialist findings 7668d404, bd91afb2 and a739c556; reproduced here through the real CTOModule (council proposal) rather than a stub.

     whole finding

     JudgeTest.test_realCtoExecuteInsideUnlockSkipsHookFlush (test/scratch/Judge.t.sol): launch a no-tax coin, fill the curve, vault.claim(coin) so the vault balance is 0; the council proposes a takeover to a contract recipient (proposeByCouncil) and 7 days pass.

     An outside router (PoolSwapTest) buys the coin with 1,000 IMD: hook.pending(coin).creator == 5e18, nothing flushed.

     A contract calls poolManager.unlock and inside unlockCallback calls cto.execute(coin).

     Expected (R1-A4-8, test_cto_hookPendingFeesGoToOldRecipient): the creator receives the 5 IMD pending in the hook before the switch.

     Actual: execute succeeds, recipientOf(coin) == community, hook.pending(coin).creator is still 5e18, the creator's balance is unchanged; after hook.flush(coin) and vault.claim(coin) the community recipient holds 5e18 and the creator never gets it.

     The same test passes once ctoSetRecipient (or execute) reverts while the PoolManager is unlocked.

   • lowThe first buy of a holder-tax coin (usually the creator's dev buy) gets its own holder tax back: the tax is parked because no holder is eligible yet and is credited at the next trade to the first buyelaunchpad/contracts/src/PadToken.sol:84

     BondingCurve.buy routes the holder share to the token and calls distribute() before the buyer receives tokens (BondingCurve.sol:227-231) so that 'a buyer never earns from their own buy'. But distribute() returns early while eligibleSupply < MIN_ELIGIBLE (1e18), which is always the case for the first buy of a coin (and again whenever every holder has sold back below one token in total).

     That buy's holder tax stays parked on the token (balance - accountedImd) and is credited at the next distribute(), which runs inside the next trade's _routeFees before that trade's buyer receives tokens: at that moment the first buyer is the only eligible holder and is credited the whole parked amount.

     With a dev buy at launch (exempt from snipe tax and max-buy, D-28) the creator therefore recovers 100% of the holder tax on an arbitrarily large dev buy, while every later buyer's holder tax goes to others. Nobody else loses funds and the amount is the first buyer's own tax, so Low: an asymmetry between the first buy and every other buy that contradicts the ordering the code comment promises.

     Fix preserving the design: when the holder part would be parked (eligible supply below the minimum), have BondingCurve.buy send that trade's holder part to the growth fund or the creator vault instead of the token, or let PadToken hold it in a bucket that is only credited after the buyer's own transfer; or document the behaviour.

     Actual: the creator's PadToken.claim() pays 30029999999999999999 wei (its own 30 IMD dev-buy tax plus alice's 0.03 IMD, minus 1 wei rounding).

     The same happens without a dev buy for whoever buys first (specialist 79e1a878: alice buys 100 IMD, bob buys 1 IMD, withdrawableDividendOf(alice) == 3029999999999999999).

   • infoPadHook._seed sweeps the hook's entire IMD and coin balances at every graduation, not only that graduation's rounding dustlaunchpad/contracts/src/PadHook.sol:194

     The 'rounding dust' sweep reads the hook's whole balance of IMD (sent to the growth fund) and of the graduating coin (burned). Any IMD that reaches the hook by other means (a user transfer by mistake, a creator who set its fee recipient to the hook and claimed) is moved to the growth fund at the next graduation of any coin instead of being recoverable, and any of the coin's tokens sent to the hook before its graduation are burned.

     No protocol or third-party funds are at risk: the hook never legitimately holds IMD outside _flush (take and forward in one call, inside the hook's own unlock where no outside code runs) and _seed; the only loser is whoever sent tokens to the hook. Consider computing the dust from the amounts actually paid (amount0 / amount1 minus the settled delta) rather than from balances, or documenting that the hook address is a sink.

     JudgeTest.test_seedSweepsStrayHookImd (test/scratch/Judge.t.sol): alice transfers 1e18 IMD to address(hook); a no-tax coin is launched and its curve filled.

     Expected: the 1e18 IMD remains on the hook or is retrievable.

     Actual: after graduation imd.balanceOf(hook) == 0 and the growth fund's balance rose by more than 1e18 + the graduation fee (TARGET * 99 / 10_000).

   • infoARCHITECTURE-v1 §4.3 lists the coin snipe tax as a FeeSplitter inflow; the code, GrowthFund's header and HANDOFF send it to the GrowthFundlaunchpad/ARCHITECTURE-v1.md:157

     BondingCurve.buy sends the snipe tax straight to config.growthFund() (BondingCurve.sol:229: if (snipe != 0) imd.safeTransfer(config.growthFund(), snipe);); the test test_snipeTax_decaysAndGoesToGrowth, GrowthFund.sol:9 ('graduation fees and snipe taxes') and HANDOFF agree. ARCHITECTURE-v1.md §4.3 instead lists the snipe tax among the FeeSplitter's inflows, which would give stakers 40%, workers 25%, growth 20% and the treasury 15% of it.

     DECISIONS names the destination only for the $PONDPAD sale's snipe tax (D-35, growth), not for coins. Documentation mismatch only; whichever is intended should be stated once in ARCHITECTURE and DECISIONS. Specialist finding 3237c66d, verified against the code and the docs.

     Launch a coin and buy 100 IMD inside the snipe window (test_snipeTax_decaysAndGoesToGrowth in test/PondPad.t.sol): the growth fund's IMD balance rises by the full snipe tax and the FeeSplitter receives only the 1% protocol part.

     Expected per ARCHITECTURE-v1.md line 157: the snipe tax reaches the FeeSplitter.

     Actual: it reaches the GrowthFund.
