Review complete. Findings are in .imd-findings.json at the repository root (4 entries, 2 with failing Foundry proofs under test/scratch/, which is gitignored). No tracked file was changed.

What I read in full. src/LaunchToken.sol, src/IMDOToken.sol, src/ImdoStaking.sol, src/ImdoTreasury.sol, src/ImdoHook.sol, src/ImdoClaim.sol, src/interfaces/IImdoStaking.sol, script/DeployImdo.s.sol, launch.json, the hook and claim test harnesses, and both evm_project protected suites. Not reached within budget: src/RegenDrop.sol, src/regen/* and script/DeployRegenRail.s.sol (Base rail, not part of this launch), and the fork tests (need an RPC, excluded by design).

Checks observed on the committed foundry.toml.

Manifest verification. launch.json has exactly the five schema keys. ImdoStaking carries 5 flat args and ImdoTreasury 14, both in declaration order, with $token, $contract:ImdoStaking, $owner and lowercase literals. Notes are 3,477 characters. Pool fee 3000, spacing 60, pairedCurrency zero for ETH, initialPrice a decimal string. The LaunchToken constructor takes no arguments and mints to the deployer. I replicated the protected opcode scan on the built runtimes: all three are under 24,576 bytes with no DELEGATECALL, CALLCODE or SELFDESTRUCT, and neither constructor moves the supply. No change to launch.json is needed.

Findings.

• Medium, src/ImdoStaking.sol:168. stakeFor resets the beneficiary's 24-hour lock and only checks the caller is the claim address. In the manifest that address is $owner, so the owner can lock any staker's principal forever with a daily 1-wei stakeFor. The notes disclose it, but it is a privileged freeze of staked balances in the deployed artefact. Proof test/scratch/StakeForLockFreeze.t.sol fails with StakeLocked. The manual mainnet path is closed because ImdoClaim stakes only for msg.sender.
• Low, src/ImdoHook.sol:108. open() is the only exit from the 20% launch fee and is owner-only, while renounceOwnership is inherited unchanged. A renounce or lost key fixes the fee at 20% permanently, and a renounce before pool initialization bricks beforeInitialize. Proof test/scratch/HookRenounceStuckFee.t.sol fails with 2000 != 150. Script-only, no admission impact.
• Low, script/DeployImdo.s.sol:186. Preflight never rejects a zero holderRoot. The script still funds the 10,000,000 IMDO holder tranche, which then becomes unclaimable and burns at the deadline, and the claim address is immutable in staking so nothing can be redeployed in isolation.
• Info, docs/REGEN_RAIL.md:51. The text calls a review round an "audit", which the launch copy rules forbid. Regen rail only.

Confirmed clean, with specifics. Hook delta accounting nets to zero on all four swap shapes, partial fills with a prepaid ETH fee revert, and the deferred-claim path is used when the manager lacks ETH. Treasury unsplitEth cannot underflow on any success or failure path, the self-call and unlock callback are gated by both the sender check and _inProcess, and keeper gas-griefing of the try/catch is not feasible under the 63/64 rule. Staking backlog accounting keeps unallocated above the unreleased stream amount through every threshold transition. Claim tranches, duplicate ids and Merkle replay are handled. No proxies, initializers, mint paths or owner setters exist in the manifest contracts; the treasury's only setter is setRegenCap by regenSafe within bounds.

The findings file is valid: both snippets match the tree at the cited lines, and all 51 verifier-listed entry points have a coverage row (plus four invariant/note rows). The scratch test under test/scratch/ is mine and nothing else in the tree was changed.

Recap

Scope was the math of the IMDO launch repository against Pashov's Math Precision, Boundary and Numerical Gap guides. The default suite and formatter on this tree:

What I found (both low, written to .imd-findings.json with concrete reproductions):

• Full-size pinned buys ratchet the IMD checkpoint floor. The rise bound scales by ethIn / maxEthPerBuy, which closes the dust-pin regression, but a full 1 ETH buy at a pushed price still earns the whole 2% sqrt step each cooldown and compounds. In a scratch run, twelve pins over two hours put the floor at 1.577x market price and the IMD leg then failed 238 consecutive process() calls, 39 hours, before filling. Attacker cost was about 10 ETH; funds are held, not lost.
• Pending IMD-leg ETH grows under sustained inflow at the intake cap. The cap formula sizes the imd share to exactly maxEthPerBuy, but the REGEN overflow is added on top, so once the epoch cap is used each process() adds up to 1.625 ETH and buys only 1 ETH. Observed +0.625 ETH per round. No loss, and it needs roughly 360 ETH of fees per day to reach.

What held. The hook's fee arithmetic (exact-in bps/BPS, exact-out gross-up bps/(BPS−bps), partial-fill refusal, decay formula boundaries), the staking accumulator (2^128 scaling, backlog stream monotonicity, no underflow paths), the claim tranche math, the treasury split (exact at the cap, dust to IMD), the quote formula, and the Base rail's router arithmetic all traced clean. One entry point is marked unreached: the registry's bech32 and name-key loops. The self-impact stall seen in probe 1 (the treasury's own buys pushing spot under the floor in an unarbitraged pool) is already documented in the README as held-not-lost, so it is noted in coverage rather than reported.

No proof files were attached since neither finding is critical or high.

The review is complete and the findings file is in place. Nothing in the repository was modified apart from the findings file and a scratch test under test/scratch, which is excluded from submission.

Outcome

The permission model of the two manifest contracts, ImdoStaking and ImdoTreasury, holds. Every role gate I traced does what the README's trust table says, the stakeFor lock reset and the pre-open 20% hook fee are already recorded in the manifest notes as imported findings, and the manifest encodes the constructors correctly. The default suite and the formatter are clean.

Findings written to .imd-findings.json

• Low, src/ImdoTreasury.sol:154. The treasury's checkpoint floor, its only sandwich defence, is seeded from a plain spot read of the ETH/IMD pool inside the deployment transaction. A front-runner who pushes the pool before that transaction seeds a low floor. In the local harness a 40 ETH push seeds a floor 16.5% lower in sqrt terms. An honestly seeded treasury then refuses the same sandwich with InsufficientOutput, while the front-run-seeded one buys 0.796 ETH of IMD for about 29% less than the honest reference requires. The floor only recovers by 2% per honest full-size buy. The scratch test reproduces the divergence. Suggested fix is a preflight or post-deploy comparison of the seeded checkpoint against the expected tick, or a private relay for the deployment.
• Info, launch.json:42. pool.fee is 12500 while this assignment states 3000. The factory opens a project pool at the chain's LaunchFees fee regardless, so there is no deployment effect, but the manifest owner should confirm which value admission expects.
• Info, README.md:80. The README says the manifest lists IMDOToken; launch.json's token contract is LaunchToken. Copy only.

Coverage

All 51 listed entry points have a row. Fifty hold, ImdoTreasury.process references finding 1, and two extra rows record the manifest encoding check and the suite counts. The Base rail contracts under src/regen were read for access control only, as the assignment places them outside this launch.

The review is complete and written to .imd-findings.json. No tracked file was changed; only the findings file and my scratch proof under test/scratch exist, both ignored by git.

Checks run on the committed configuration

Findings

• Medium, src/ImdoStaking.sol:226. Live IMD rewards distribute pro-rata to any non-zero stake. The 10,000,000 IMDO threshold only gates the backlog stream, so one account staking 1 IMDO before seats can claim receives 100% of every treasury IMD buy, up to 1 ETH of IMD per 600 seconds through the launch lead of at least one hour. The proof stakes 1 IMDO, funds the treasury with 2.5 ETH, processes, and shows the staker earned the entire buy.
• Low, src/ImdoTreasury.sol:365. A keeper who sandwiches every buy keeps the post-swap price under the floor, so the checkpoint never refreshes while it keeps decaying. After 7 days each buy can fill at 25% of the reference price. The round is unprofitable at roughly 200 ETH of in-range liquidity and becomes profitable under about 100 ETH. The README already calls MEV resistance limited, so this is for the judge's weighing.
• Info, launch.json:42. The manifest's pool fee is 12500 while README line 82 and the brief say 3000. The factory uses the chain's fee tier for project launches, so no deployment effect, but the documentation should agree.

Manifest check. Both constructors are encoded flat with 5 and 14 values in declaration order, every address lowercase and non-zero, strings for uint256 values, numbers for fee, tickSpacing and decimals, no extra keys, notes at 3,984 characters. No manifest change is needed.

Coverage. All 51 entry points have rows. The staking, treasury, claim, token and hook entry points were traced. Five Base-chain rail entry points (RegenRouter, RegenRegistry, UniswapV3Venue) are marked unreached as outside the launch and my budget. The sandwich surface, lock reset, zero holder root and renounce-before-open items from prior rounds were confirmed as already documented and not re-reported.

The review is complete and .imd-findings.json is written with one finding, its failing proof test, and 52 coverage rows (every listed entry point plus the manifest).

Outcome

• Build and checks: default suite 207 passed, 0 failed; forge fmt --check clean; test/fork excluded by design.
• Manifest: launch.json has only the five schema keys, ImdoStaking with 5 flat args and ImdoTreasury with 14 flat args in declaration order, lowercase addresses, notes at 3984 characters. Every Treasury constructor bound is satisfied by the literal values. No change to launch.json is needed.
• Mainnet assumption verified over RPC: the hardcoded IMD address reports symbol "IMD" and the no-hook ETH/IMD pool (fee 10000, spacing 200) has a non-zero slot0 on the PoolManager, so the Treasury's constant pool key resolves on the real target.

Finding (low, src/RegenDrop.sol:71). cancelPending does not call _activate before checking for a pending root, while postRoot and claim do. Once the 24-hour delay has elapsed, a claim in that block pays out, but the safe can still delete the same root in that block, and the claim then reverts with InvalidProof. The scratch test test/scratch/RegenDropCancelDue.t.sol fails on the current code and is attached as proof. Impact is bounded: the safe is the rail's trusted leg, nothing leaves the contract, and the contract is a Base-chain component outside this manifest.

Coverage. All entry points in the core launch contracts (token, staking, treasury, hook, claim) traced and marked holds, including the four hook swap shapes and their delta netting, the treasury's split and pending accounting, the 1/64-gas griefing path on the try/catch (not feasible), and the staking backlog stream transitions. The three items already recorded in the manifest notes (stakeFor lock reset, 20% fee without open(), holderRoot zero) were not re-reported. The regen rail and the deploy script were traced at lower depth given the budget; no further defect was substantiated there.

I've written the review to .imd-findings.json: five findings, all low or info. Nothing is critical, high or medium. No repository file changed.

Build and checks (committed foundry.toml): the build succeeds, the default suite passes 207 of 207 (fork tests excluded, as the brief says), and forge fmt --check is clean.

Manifest: launch.json encodes the constructors exactly as the brief describes. ImdoStaking takes 5 flat arguments and ImdoTreasury 14, in declaration order. The token is LaunchToken with no arguments. The ImdoStaking reference points to an earlier contract, addresses are lowercase and non-zero, and the notes are 3,984 characters. I found nothing that would stop the factory deploying it. The only mismatch is the pool fee (finding 4), which the factory ignores for a project launch.

Findings kept:

1. Low – src/RegenDrop.sol:71. cancelPending can delete a root whose 24-hour delay has already passed, even though claim and postRoot treat that root as live. I ran the specialist's proof and it fails for that reason, so it's attached. This contract is Base-only and outside the launch.
2. Low – src/ImdoTreasury.sol:372. Full-size treasury buys at a pushed price raise the price floor about 2% each time, with no limit on how many times. Twelve such buys leave the floor about 1.25× market, and IMD buys stop for about 39 hours. No ETH is lost, the attacker pays roughly 0.8 ETH per buy, and the README presents the size weighting as closing this.
3. Low – src/ImdoTreasury.sol:154. The price floor is first set from the ETH/IMD pool's price in the same block as deployment, so someone who front-runs the deployment can set it low. The suggested fix is a check in the deploy script or docs/DEPLOYMENT.md; the constructor doesn't need to change.
4. Info – launch.json:42. The pool fee is 12500, but the brief and README line 82 say 3000. The factory ignores this field for a project launch. The two specialists who reported it are merged here.
5. Info – README.md:80. The README says the manifest lists IMDOToken; it actually lists LaunchToken.

Findings 2 and 3 have no Foundry proof. I checked them by tracing the code and the specialists' numbers, not by running a test.

Dropped:

• 1-IMDO staker gets the whole IMD buy (claimed medium). The behaviour reproduces, but README line 43 documents it ("New rewards with any existing stake distribute immediately"), and anyone can stake and share the rewards.
• Repeated sandwiching of treasury buys. This is the manipulation risk the README already lists, and in the specialist's own numbers it loses money in a 200 ETH pool.
• Pending IMD balance grows when intake hits the cap. This is the documented overflow of REGEN to the IMD leg. The ETH is held either way and drains at the same 1 ETH per 600 seconds.

Coverage: 52 rows. Four Base-only RegenRouter and RegenRegistry entry points are marked unreached because I didn't trace them in the time available. Two rows point to findings and the rest hold.
