I've written the review to
.imd-findings.json(9 findings) and changed no repository files. The one test I wrote undertest/scratch/has been run and then deleted, and the working tree is clean. Nothing was deployed or submitted. So there is no launch record, no addresses, no transaction references and no new commit; the source is still commit56673ae.What I read: all 16 source files (the four factories, the hook, the crew token and its IMD wrapper, the ledger, buyback, price-oracle and V4-engine modules, the fee library, the swap router, the airdrop, the VRF adapter and the plan verifier), plus
launch.json,foundry.toml,README.mdand the test suites. The existing tests pass (92 passed, 2 skipped because they need a mainnet RPC). I didn't reach: the live Chainlink VRF coordinator, the Uniswap V4 PoolManager on mainnet, IMD's real ProjectFactory,floor/OwnerChecks.sol(not supplied), the future V2 receiver contract, and the inputs behind the committed hook hash.Findings, most severe first:
- High – the season can freeze permanently if randomness never arrives (
MugiIMDGameHook.sol:223). Once an elimination is requested, the only way forward is the VRF callback. There is no timeout, no way to request again, and no recovery after launch. If the Chainlink request is never fulfilled (for example the subscription is underfunded until the request expires, or it is cancelled), all pool ETH is locked and every crew token is frozen. A Foundry proof is attached; it fails on the current code for exactly this reason. - Medium – the committed V2 target is not enforced (
:406). The hook's constructor checks the V2 target argument and then discards it.migrateToV2lets the owner send all leftover ETH and the hook's remaining survivor tokens to any contract they choose, and can be called more than once. - Medium – players lose unclaimed survivor tokens at finalize (
MugiIMDLedger.sol:165). Players earn survivor tokens from eliminated crews but can only claim them while the season is live and before the cutoff. Anyone can callfinalize()at that cutoff, which wipes these claims, and the tokens backing them go to the V2 target. - Medium – things the
evm_contractsrules forbid, which admission must explicitly accept:- the owner can pause all trading with no time limit (
:218); - token transfers are frozen outside the live window, forever for eliminated crews, and forever for every crew after finalize or an abort (
:438). The brief doesn't mention the freeze of the surviving crew after finalize; - the hook mints new crew tokens after launch (
:295,:278); - the four recorded factories create 19 descendants that need configuring after deployment, and only the factories' bytecode is in the signed artifact set (
MugiV1IMDDeploymentFactory.sol:94).
- the owner can pause all trading with no time limit (
- Low – whoever owns the plan verifier can be any address. That owner can change the oracle signer and get a skewed buyback plan approved, within the ±25% band per crew.
- Info – the committed hook hash
0xbc3c…4359can't be checked from this repository. The team, community, V2 target and supply values behind it aren't stated anywhere I could find. If it doesn't match the compiled hook,deployHookcan never succeed and a new factory launch would be needed.
Admission-floor check: the four factories should pass. Their runtimes are 7,748, 18,646, 16,219 and 12,215 bytes, all under the 24,576-byte limit. A copy of the protected check's opcode scan finds no reachable DELEGATECALL, CALLCODE or SELFDESTRUCT. None of their constructors call another contract.
launch.jsonmatches the brief's manifest exactly.The disclosed architecture is incompatible with standard
evm_contractsrules on four points: the pause, the transfer freezes, minting after launch, and setup after deployment. It can only launch if source admission explicitly accepts these disclosed rules.

proof · a Foundry test the fix has to passmediumv2MigrationTarget_ constructor argument is validated and then discarded; migrateToV2 sends all residual ETH and survivor inventory to any owner-chosen contractsrc/imd/MugiIMDGameHook.sol:406
Deploy the hook with v2MigrationTarget_ = X (a contract).
Run the season to Finalized.
Owner deploys Y whose receiveV1Finale(uint8,address,uint256) payable forwards msg.value to the owner EOA and calls migrateToV2(Y).
Expected: revert because Y != X (committed target).
Actual: succeeds; Y receives the final pool's ETH principal plus all non-reserved hook ETH and the survivor token inventory.
A second migrateToV2 call later also succeeds and sends any ETH that arrived since.
mediumPlayers' unclaimed survivor-token escrow (earned from earlier eliminations) is erased at permissionless finalize and handed to the V2 targetsrc/imd/modules/MugiIMDLedger.sol:165
Alice holds crew 0 tokens; crew 0 is eliminated in round 1, so previewAccount(Alice) shows claimable survivor tokens.
Alice does not call claimTokens before the 9th round's nextCutoff.
Anyone calls finalize() at nextCutoff.
Expected: Alice can still claim her escrowed survivor tokens (or they are earmarked for her).
Actual: previewAccount(Alice).claimableTokens are all 0, claimTokens reverts InvalidState (phase Finalized), and migrateToV2 moves the backing tokens to the owner-chosen target.
mediumAdmission: owner can pause all trading at any time with no bound (setPaused)src/imd/MugiIMDGameHook.sol:218
The owner can toggle paused at any time; _requireLive then reverts every beforeSwap (all buys/sells through the V4 pools) and every executeBuyback/executeOwnBuyback. There is no maximum duration or timelock. Elimination, settlement and claims still proceed (as disclosed), so holders can be forced to ride eliminations without being able to sell.
The launch rules forbid pausing/freezing holder balances; the brief discloses this pause intentionally and asks it not be silently removed. It must be explicitly accepted by evm_contracts source admission or the launch is incompatible.
Live season, Alice holds crew 3 tokens.
Owner calls setPaused(true).
Alice sells through MugiIMDSwapRouter.sell(3, amount, 0, deadline): reverts (beforeSwap -> _requireLive -> InvalidState).
Anyone calls requestElimination/settleRound at the cutoff; if crew 3 is drawn, Alice's position is converted at 3/4 while she was unable to exit.
Expected under evm_contracts rules: no owner trading pause.
Actual: unbounded owner pause.
mediumAdmission: crew-token transfers are frozen outside the live window, permanently for eliminated crews, and permanently for every crew after finalize or abortsrc/imd/MugiIMDGameHook.sol:438
beforeTokenTransfer reverts TransferFrozen for any non-protocol transfer unless phase == Live, before nextCutoff, and the crew is alive.
Consequences: (a) all transfers freeze in Setup, AwaitingRandomness, OutcomeReady, Settling; (b) eliminated-crew balances can never move again; (c) after finalize() (phase Finalized) even the surviving crew token is non-transferable forever in V1; (d) after abortPrelaunch (phase Aborted) every token, including airdrop or LP-returned balances, is frozen forever.
This is the disclosed elimination rule, but it is a freeze of holder balances that the evm_contracts recipe forbids; admission must accept it explicitly. Item (c) is not stated in the brief and should be disclosed (survivor holders keep only a non-transferable V1 receipt).
Run a season to Finalized.
Bob holds 100 survivor tokens and calls token.transfer(carol, 1).
Expected (standard ERC20 / evm_contracts): succeeds.
Actual: reverts TransferFrozen because phase == Finalized.
Likewise after owner abortPrelaunch(): any transfer reverts TransferFrozen permanently.
mediumAdmission: crew tokens are minted after launch by the hook during settlementsrc/imd/MugiIMDGameHook.sol:295
After launch the hook mints new survivor-crew supply in every settlement: _addMatchedLiquidity mints the tokens matched to re-added ETH (line 295) and _beginSettlement mints migration escrow (line 278, minted[i] from ledger.recordElimination). mint/burn are restricted to the hook (MugiCrewToken.onlyHook), as disclosed, but post-launch minting is listed as forbidden by the evm_contracts launch rules; admission must accept it explicitly. Supply is not capped at initialSupply.
Launch a season with SUPPLY = 1,000,000e18 per crew.
After round 1 settleRound(10), totalSupply() of each surviving crew token exceeds 1,000,000e18 by the minted escrow plus matched-liquidity tokens (each seeded at initialSupply, then mint(address(this), needed)).
Expected under evm_contracts rules: no mint after launch.
Actual: supply increases every round.
mediumAdmission: the four recorded factories exist to create 19 descendants that are configured after deployment; only the factories' bytecode is in the IMD artifact setsrc/imd/MugiV1IMDDeploymentFactory.sol:94
Execute the IMD launch of the four factories: no hook, token, module or pool exists afterwards (MugiV1IMDDeploymentFactory.hook() == address(0), tokens(0) == address(0)).
Only after owner calls deployHook(salt, initCode), deployModules(config), deployForHook x2, bindAccounting, configure and 10x seedPool does a playable application exist.
Expected under evm_contracts: application fully configured in constructors.
Actual: 19 descendants and multiple owner configuration calls after deployment.
MugiIMDVerifier owner (arbitrary imdVerifierOwner) can rotate the oracle signer and pin any buyback plansrc/game/MugiIMDVerifier.sol:90
deployModules passes c.imdVerifierOwner unchecked. That owner can setPolicy to its own signer (panel/quorum minimum 2 is self-reported in the signed struct) and pinRequest any plan hash, so any plan whose per-crew allocations lie within the 75%-125% band enforced by MugiIMDBuybacks.approve can be approved by one key.
Impact is bounded to redistributing a round's buyback budget between crews, but it is an additional privileged party not named in the brief (protocol owner is 0x20714d50...).
deployModules with imdVerifierOwner = V. V calls setPolicy(V_signer,2,2,1 days), pinRequest(id, q, h, t) for a plan giving crew A 125% and crew B 75% of the equal share, signs an attestation with panelSize=quorum=agreed=2. approvePlan(plan, proof) succeeds and executeBuyback spends the skewed allocation.
Committed hookInitCodeHash 0xbc3c...4359 cannot be verified from the repository; a mismatch makes the deployment factory permanently unusablesrc/imd/MugiV1IMDDeploymentFactory.sol:96
hookInitCodeHash covers MugiIMDGameHook creation code plus abi.encode(owner, manager, team, community, v2MigrationTarget, initialSupply). The brief gives owner 0x20714d50f4675c366de30b603728a90ddddb240f but not team, community, v2 target or supply, and no test or inventory entry pins 0xbc3c1605...4359, so the reviewer could not reproduce it. The hash is immutable; deployHook also requires the hook's owner_ to equal the factory owner.
If the hash was produced from any other compiler setting, source byte, or argument, deployHook reverts InvalidHookInitCode forever and a new factory launch is needed.
Compute keccak256(abi.encodePacked(type(MugiIMDGameHook).creationCode, abi.encode(0x20714d50f4675c366de30b603728a90ddddb240f, 0x000000000004444c5dc75cB358380D2e3dE08A90, TEAM, COMMUNITY, V2, SUPPLY))) from this tree with the pinned foundry.toml and compare with 0xbc3c1605ac7a5e7781e7923e764c5e673c9480991b0d532f1799b78af4ac4359 before launch. If not equal, deployHook(salt, initCode) reverts InvalidHookInitCode for every initCode except a preimage of the hash.
