The review is complete. The findings file holds six substantiated findings, none critical or high, so no proof files were attached.

Outcome. The CHEESE V2 source at commit 65924ab builds with the pinned toolchain, all 189 existing tests pass, all five runtimes are under the EIP-170 limit, and no reachable DELEGATECALL, CALLCODE or SELFDESTRUCT exists in any runtime. I found no reproducible loss-of-funds, accounting, reentrancy or arithmetic defect in the production contracts. The code has clearly been through prior revision rounds and the controller's defensive Core reads, farm accounting and fee paths held up under inversion.

Contracts read in full: CheeseEmissionController, CheeseFarm, CheeseToken, CheeseFarmERC20, CheeseFarmETH, CheeseFarmSIMD, SqueekIssuance, all interfaces, the deploy script, the mock Core and base fixture, SECURITY.md and the Squeekchain verification record. Test files were skimmed by name and coverage claims, not read line by line.

Live Squeekchain checks (read-only, Sepolia): the official deployment manifest and SqueekCore ABI were reachable. The proxy and implementation addresses, state() eight-word and configuration() eleven-word shapes, round duration 600, block units 1e9, genesis 1793735400 and issuance constants all match the controller. The anchor read roundPage(r, r, 0) returns the point position on the real proxy, including round 0, so activation will capture h0 correctly. I did not independently re-run the SqueekMining issued() comparison; the repository's verification record documents it. The real sIMD address remains unverified as the brief states.

Findings recorded:

• Medium: core wiring (bindToken, addPool, setAsset, activate) is post-deployment owner configuration. The brief mandates it and the circular references make it unavoidable, so this is a launch-policy conflict for the adapter and admission reviewers, not a code bug.
• Low: owner can route 100% of future emission to an owner-controlled contract through addPool. Reproduced: 117,586 CHEESE minted to a sink in one round.
• Low: the retained 14% fee flows to any remaining share. Reproduced: a 1-wei position captured 70 ETH of a 1000 ETH exit's fee.
• Low: just-in-time staking around a Core certification takes a full round's rewards. Reproduced: 14,698 CHEESE for a zero-duration 10 ETH stake.
• Low: sIMD pool points are forfeited until setAsset, and anyone can trigger forfeiture via claim. Reproduced: 29,396 CHEESE forfeited in one round.
• Low: renounceOwnership after pause freezes emission and deposits permanently.

Trust assumptions not reported as defects: owner and guardian can pause emission and deposits (holder balances are never frozen), owner can skim surplus to Treasury and repoint Treasury. Scheduled emission minting after launch is the product itself and is capped at 2.1B lifetime.

For the adapter: no Solidity change is required by these findings. The procedural items are to add the sIMD pool at weight 0 or set the asset before activation, keep the brief's owner-only checklist as pending actions, and treat the single-EOA owner's emission-routing power as a known trust assumption.

Prepared the launch package from commit 65924ab66aa6e2197d9a781220678c29553165cf, preserving production Solidity.

• Build and 189 original tests passed with the required seed.
• 14 launch/audit tests, 11 verifier tests, and 2 real-Core fork tests passed.
• All five bytecode hashes and local runtime bindings match.

See ADAPTATION.md, constructor values and owner Etherscan steps, and verification results.

Not deployed. No new addresses, transaction hashes, or Swarm Job URL are available. Wallet authentication, exact Forge 1.8.5 reproduction, independent review, and explorer verification remain pending. The explorer API returned HTTP 403. Emissions remain inactive; real sIMD remains unconfigured.

launch.json is written and verified. The full suite plus my scratch deployment check pass with the verifier's fuzz seed, and the only changed tracked file is launch.json.

What the manifest contains

Five contracts in constructor dependency order, matching the exact signatures in the accepted source and the brief:

• CheeseEmissionController takes $owner, the official Sepolia SqueekCore proxy, and the owner wallet as Treasury. Guardian defaults to the owner inside the constructor. The constructor only stores the core address, so it survives the empty-chain rehearsal.
• CheeseToken takes the owner wallet three times for the Team, Treasury and Liquidity premints, then the new controller as the immutable emission authority.
• CheeseFarmERC20 takes $owner, the new controller and the new CHEESE token as its asset.
• CheeseFarmETH and CheeseFarmSIMD take $owner and the new controller. The sIMD farm has no asset argument, so it deploys unconfigured and inactive as the brief requires.

The notes field records the imported commit, tokenomics, Hamster Bite fee split, the read-only SqueekMining reference, and the full pending owner-only Etherscan checklist ending with activate(). It is well under the character limit and emissions are not activated by the launch.

Checks run

• Manifest shape check: exactly the keys kind, contracts and notes, string arguments, unique names.
• Scratch test in test/scratch deploys all five with the manifest's arguments through a factory-style CREATE2 probe on an empty chain, then asserts owners, treasury, guardian, core binding, emission authority, the 210M premint to the owner wallet, farm controller and asset bindings, runtime size under the EIP-170 limit, and that the factory owns nothing.
• Full suite with the pinned fuzz seed: 190 tests passed, 0 failed.

Left for the deployment stage

The Swarm job URL, transaction hashes, deployed addresses and on-chain bytecode verification can only be produced by the deployment service after this manifest is admitted, so they are not in this deliverable. The owner-only configuration calls listed in the notes remain pending for the requester.

The review is complete. .imd-findings.json holds two substantiated items and a coverage row for all 57 listed entry points plus three invariants. No production file was changed; the scratch test lives under the gitignored test/scratch/.

Outcome: no permission bypass found. Every state-changing entry point in the controller, the three farms and the token has a guard that matches its effect. The full suite of 189 tests passes on this tree.

What I reported

• Low, finding 1. One-step renounceOwnership() is inherited by the controller and all three farms although the brief says ownership must never be renounced. Paired with the asymmetry that the guardian or owner may pause but only the owner may unpause, an owner renounce followed by a guardian pause freezes the protocol permanently. Deposits revert on every farm and no emission is ever priced again. Reproduced in a scratch test. The repo already documents this as an operational rule in docs/OFFICIAL_SEPOLIA.md, so it is a trust assumption on the owner key, not an outsider bypass.
• Info, finding 2. The owner can register any contract answering the two farm getters as a pool and reweight the real pools to zero, routing the whole remaining schedule to an address of its choice. It is prospective and schedule-bounded, touches no principal or pulled rewards, and docs/SECURITY.md item 16 already acknowledges it. Recorded so the judge can weigh it against the brief's "no arbitrary owner minting" wording.

What I traced and found sound in the permissions area

• Access Control pass. Roles map cleanly: owner, guardian (pause only), pool farm (pullRewards by msg.sender == pool.farm), controller (onPoolRegistered), self (transferTreasuryToken), emission authority (mintEmission). Constructors take an explicit owner and reject zero, so the factory never holds a role. Zero-address locks are blocked on setTreasury, setGuardian and setAsset.
• Asymmetry pass. Every allocation writer syncs and settles before changing weights, so no in-flight emission is redirected. Disable keeps accrued pullable; enable resets the accumulator. Deposit blocks while paused or unsynced; withdraw and claim never do. Pre-registration deposits earn nothing retroactively (confirmed by scratch test).
• Trust Gap pass. setTreasury redirects deferred treasuryOwed, which is intended and the brief sets treasury equal to owner. Reentrancy through ETH or token pushes is closed by nonReentrant and the self-call boundary.
• Deployment config matches the brief: the approved address for owner, treasury, guardian and all three premint recipients, official SqueekCore, no activation, sIMD unconfigured.

Not reached within budget. Economics-side checks (Hamster Bite rounding, share-price edge cases) and the Squeek schedule math belong to other specialists and were not re-derived here. I did not verify the live Sepolia SqueekCore bindings on chain.

The review is complete. The findings file is written, all snippets match the tree, and all 57 entry points have coverage rows.

Outcome: the math in CHEESE V2 at commit 65924ab holds up. I found one low-severity precision defect and two informational notes, and no critical or high issues in the Math Precision, Boundary or Numerical Gap areas.

What I verified

• Issuance schedule against the live chain. The compiled-in SqueekIssuance.issued equals the live Sepolia SqueekMining issued() at all 17 boundary inputs I probed, including the bonus end, each halving, the schedule end and the uint64 maximum. The live issuanceSchedule() fields are identical to the constants.
• SqueekCore boundary. Live state() and configuration() return exactly the 256 and 352 byte payloads the controller requires, with a 600 second round and 1e9 units per block. Live roundPage(r, r, 0) returns start == end == the position after round r, which is exactly the h0 semantics the controller and the mock assume.
• Share, fee and reward arithmetic. No overflow in any intermediate, including the 512-bit reward debt path with a 1-share attacker. Gross never exceeds the principal reserve, so the last-depositor path cannot underflow. Inflation through the retained fee costs an attacker roughly a thousand times the victim's rounding loss because of the virtual offset.
• Weight accounting. All uint16 casts are preceded by uint256 bound checks, and the batch lower-then-raise ordering keeps every intermediate sum within 1,000 points.
• Full suite. 189 tests pass.

Findings written to .imd-findings.json

1. Low. Hamster Bite rounds down. A withdrawal with gross 6 wei pays no fee at all, and gross 50 wei yields fee 7, retained 7, Treasury 0. Reproduced on the fixture. Dust-scale impact, but the 85/14/1 split does not hold for small withdrawals and this edge is below the fuzz bounds.
2. Info. Reward dust stranded. Floor-accumulator plus ceil-debt leaves up to 1 wei per harvest in the reward reserve with no path to claim or sweep it.
3. Info. Allowance-equality completion branch is dead. The schedule totals 591,990 wei under the allowance, exactly as SQK does, so completion relies solely on the block count.

Not reached in depth: the deploy script, release manifest and protected tests were only skimmed, since they lie outside the math area. The permissions, economics and control-flow passes belong to the other three specialists.

Review complete. The findings file is written and verified against the tree, with two Foundry proofs that fail on the current code.

Scope covered. Economic Security, Invariant and Flow Gap passes over all production sources, the three farms, the issuance library and the token. The existing 158-test suite passes. The live-Core anchor read for h0 is covered by the authors' recorded fork test, so I did not raise it.

Findings written to .imd-findings.json:

1. High: Hamster Bite retained share captured by a zero-duration depositor. A dust deposit mined in front of a dominant staker's exit becomes the "remaining" share and sweeps the farm on its own exit. With a sole staker leaving 10 ETH, a 1000 wei front-run nets the attacker about 1.19 ETH and the Treasury receives 0.31 ETH instead of the promised 1.5 ETH. The attack also profits against honest co-stakers whenever the exiting staker holds over roughly 56% of a farm. Proof in test/scratch/RetainedFeeFrontRun.t.sol.

2. Medium: round-chunked emission split with no time weighting. Emission lands per certified round and is spread over shares at pull time. A deposit placed ahead of the Reporter's settle transaction earns a full round share. On the CHEESE farm with 100k CHEESE of honest stake, a 100k same-block deposit nets about 14,400 CHEESE after the 15% exit fee and halves the honest staker's round. Profitable whenever farm TVL is under one chunk's emission divided by 0.15. Proof in test/scratch/RewardJit.t.sol.

3. Info: exits during a Core outage or pause forgo certified-but-unpriced emission. Traced and confirmed numerically. The authors document this; recorded as a coverage note only.

Coverage record. All 57 listed entry points have rows, plus four invariant rows. Twelve rows point at the two findings, the rest hold.

Not reached in depth. The real Sepolia roundPage semantics beyond the recorded fork evidence, and the live sIMD token behaviour, which remains unverified by the brief's own statement.

Added failure-path, bytecode-integrity, and invariant tests for all three farms.

• forge build passed.
• Seeded forge test: 217 passed, 0 failed.
• New invariants: 16,384 calls, no unexpected reverts.
• All five pinned bytecode hashes match.

Only test/ changed. No live deployment occurred. Verification limits are documented in test notes.
