Implemented squeek (SQK): 18 decimals, 1 billion tokens minted once to the deployer, with no administrative powers.

Included vendored dependencies, tests, and deployment/operations documentation.

Passed forge build, forge test (34 tests), forge fmt --check, and a clean offline build.

An additional fully empty-environment run hit a Foundry runtime error: could not detect user home directory.

I found no defects in SqueekToken's permissions, and .imd-findings.json holds an empty findings list with a coverage row for each entry point.

What I reviewed: src/SqueekToken.sol is a 16-line contract that inherits the vendored OpenZeppelin v5 ERC20 (it uses the v5 _update hook) without changing it. The constructor mints INITIAL_SUPPLY (1,000,000,000 × 10^18) once to msg.sender, the factory. It adds no functions of its own.

The three guides:

• Access Control: there is no owner or role system, and no mint, burn, pause, blacklist, freeze or upgrade function. Nobody holds any role after deployment, and the supply cannot grow.
• Trust Gap: the token makes no external calls and has no hooks, callbacks or special-cased addresses. That means the transfers from the factory, the PoolManager and the distributor move exactly what they say.
• Asymmetry: transfer and transferFrom both go through the same _update path, so buys and sells through the pool behave the same. transferFrom checks and spends the allowance before moving anything, and a maximum allowance is never reduced. approve only ever sets the caller's own allowance.

Coverage: all three entry points (approve, transfer, transferFrom) are marked holds, each with a reason. I added two invariant rows: no privileged role or supply growth, and no trust gap or asymmetry. Nothing in the area went unreached.

Leads: Slither reported nothing. Aderyn's only line, the large numeric literal at line 11, is the intended supply constant and not a defect.

Tests: the existing suite passes, 34 of 34 including the invariant run. I modified no repository files. The findings file is ignored by git and is the only thing I wrote.

I found no defects in squeek (SQK) in my area: execution flow, the libraries it depends on, and its basic assumptions. .imd-findings.json has an empty findings list and a coverage row for each of the three entry points, all holds.

What the code is. src/SqueekToken.sol is a plain OpenZeppelin v5.1.0 ERC-20. Its constructor mints INITIAL_SUPPLY = 1_000_000_000 * 10 ** 18 (10^27 base units) once to msg.sender. It adds nothing on top: no extra functions, fees, hooks, owner, fallback or receive.

How I checked it:

• Dependencies: I downloaded the five vendored OpenZeppelin files (ERC20, IERC20, IERC20Metadata, Context, draft-IERC6093) at the pinned commit 69c8def and compared them. All five are byte-identical, so _msgSender, _update and _spendAllowance are the standard code.
• Execution trace:
  • transfer: zero addresses are rejected, and the balance check comes before the unchecked subtraction. The unchecked credit can't overflow because the supply is fixed at 10^27. A self-transfer leaves the balance unchanged.
  • transferFrom: spending the allowance and moving the tokens happen in one call. If it reverts, both changes roll back. A type(uint256).max allowance skips only the decrement, not the balance or address checks. from = 0 reverts.
  • approve: rejects a zero owner or spender and simply overwrites the allowance. The usual ERC-20 race when changing an allowance is standard behaviour and the README documents it.
  • No path reaches _mint or _burn after construction.
• Launch flows: transfers move exactly the stated amount, with no fees or callbacks. The factory → distributor → claimant and PoolManager settle flows therefore arrive whole.
• Bytecode: a scan of the reachable code in the 1,752-byte compiled runtime found no DELEGATECALL, CALLCODE, SELFDESTRUCT, CALL or CREATE. The ABI has only the standard ERC-20 functions.
• Tests: forge build succeeded. forge test with the verifier's seed passed 34 of 34 tests (unit, fuzz and invariant).
• Static analysis: aderyn's only line, a large numeric literal at src/SqueekToken.sol:11, is a style note and not a defect. Slither reported nothing.

What I didn't run: the protected suite. It needs the network's launch harness (floor/, LaunchLiquidity, v4-core and its environment variables), which isn't in this tree. I checked the token against each of its assertions by reading the code instead.

I changed no files. The untracked dotfiles in the repo root are /dev/null device nodes that the sandbox mounts, not files written by this review.

Created launch.json matching SqueekToken’s constructor, supply, and required launch economics and pool settings.

Validation passed: forge build and all 34 tests with the specified fuzz seed. Only launch.json was changed.

The review is complete. No defects were found in the economics area, and the findings file is written with an empty findings list and a full coverage record.

What I checked

• Economic Security. The token is OpenZeppelin v5.1.0 ERC20 plus one constructor mint. There is no oracle, fee, callback, hook, owner, pause, blacklist, mint, burnFrom, proxy, delegatecall or selfdestruct. The five vendored OpenZeppelin files hash byte-for-byte to the upstream commit named in DEPENDENCIES.md. A runtime opcode scan mirroring the protected floor found no reachable forbidden opcode.
• Invariant. The sum of balances equals the total supply of exactly 10^27 base units for the contract's life. Only the constructor reaches the mint path, the burn helper is never called, and transferFrom from the zero address reverts for every value, so there is no phantom mint. The aderyn large-literal lead resolves to the correct supply constant.
• Flow Gap. Every transfer moves exactly the stated amount with no external call, so the factory-to-distributor, distributor-to-claimant, pool seed and swap legs settle whole under Uniswap v4's before/after balance accounting. The standard ERC-20 approve race is the ordinary semantics the brief asked for and is documented in the README, so it is not reported.

Verification run

• Project suite: all 34 tests pass, including the 256-run stateful invariant suite, with the verifier's fuzz seed.
• A scratch test I wrote and then removed confirmed supply and recipient, exact launch legs, zero-sender revert paths and the opcode scan.
• The protected harness itself needs v4-core and environment variables not present here, so only its token-side checks were reproduced locally. That limit is recorded in the coverage rows.

Output. The repository root holds .imd-findings.json with zero findings and seven coverage rows: one holds row for each of the three listed entry points, plus rows for the supply invariant, the constructor mint, the economic-security surface and the launch flow seam. No tracked file was changed.

The math review of the squeek (SQK) token found no defects. The findings file at .imd-findings.json holds an empty findings list and ten coverage rows, all holds.

What was reviewed. The token is a 16-line contract: one constant and one constructor that mints it, inheriting OpenZeppelin v5.1.0 ERC20 unchanged. I checked it against every failure mode in the Math Precision, Boundary and Numerical Gap guides.

• Precision. The supply literal folds to exactly 1e27. It divides evenly by 10**18, 1,000 and 10,000, so the launch floor's swarm, pool and probe shares leave no remainder and sum back to the supply. There is no division, downcast, decimal scaling, or share math anywhere in the contract.
• Boundary. No external calls, no payable or fallback path, no bytes decoding. The only sentinel branches are the zero-address checks, and each reverts rather than silently succeeding. Allowance at max is infinite, max minus one is finite and decrements, allowance equal to the amount spends to zero, and a zero-address source fails in the allowance path.
• Numerical gap. The sum of balances equals totalSupply exactly under the project's stateful invariant suite and my own split-and-merge fuzz. The runtime ABI exposes only approve, transfer, transferFrom and views, so no path can ever grow or shrink the supply after construction.

Verification performed. The full project suite passed with the verifier seed, 34 tests including 256 invariant runs with zero reverts. Eight scratch tests I wrote for the edges above all passed and were then removed. All five vendored OpenZeppelin files hash identically to upstream at the pinned commit. A reachability scan of the runtime bytecode finds no DELEGATECALL, CALLCODE or SELFDESTRUCT. The aderyn "large numeric literal" lead is stylistic only and is not reported.

Not covered. Nothing in my area was left unreached. Permissions, economics and control flow belong to the other three specialists, though the entry points were all traced end to end here since the contract is so small.

Added 13 boundary and failure-path tests, and expanded invariants to 12 randomized actions.

forge build and forge test pass with the required seed: 47 tests passed, including 32,768 invariant handler calls.

All changes are under test/. No implementation defects were found by these checks.

I found no defects in the squeek (SQK) token, so the findings list in .imd-findings.json is empty. All three entry points are marked holds, and two extra rows cover the invariants I checked.

• Specialists and tools: none of the four specialists or the independent tester reported anything, so there was nothing to reproduce or merge. Slither found nothing. Aderyn flagged one low item, a "large numeric literal" at src/SqueekToken.sol:11. That line is just 1_000_000_000 * 10 ** 18, the intended supply of 10^27 base units, so it isn't a defect.
• The code: SqueekToken is the vendored OpenZeppelin v5.1 ERC20 with nothing changed. Its constructor takes no arguments and mints the whole supply once to whoever deploys it. It has no other mint or burn, no owner, no fees, no pause or blacklist, and no upgrade path. I read the vendored ERC20 source and confirmed its standard behaviour:
  • approve reverts if the spender is the zero address.
  • transferFrom doesn't reduce an unlimited allowance and reverts if the allowance is too small.
  • transfer moves exactly the amount asked for and reverts if the balance is too low or the receiver is the zero address.
• Launch flows: since nothing is taxed or burned, the swarm's 10% share, the pool seed and pool swaps all move exact amounts.
• Manifest and deployment: launch.json matches the code. Constructor arguments are [], supply is 1000000000000000000000000000, and decimals are 18. The contract name SqueekToken is within the 32-character limit. The deployed code is about 1.75 KB, far under the 24,576-byte limit, and contains no DELEGATECALL or SELFDESTRUCT. foundry.toml sets bytecode_hash = "none", as the launch requires.
• Tests: the project's own tests pass (47 of 47). I didn't run the protected floor tests, because they need the launch's environment variables.

I didn't change any repository files. The findings file was the only thing I wrote, and it is excluded from git, so the working tree is still clean.
