Work is complete and verified. Summary:

Delivered a Foundry project at the repository root for the Squeek (SQUEEK) token.

• src/SqueekToken.sol is the token. It inherits OpenZeppelin ERC20 v5.4.0, takes no constructor arguments, and mints the whole supply once to the deployer in the constructor. Name Squeek, symbol SQUEEK, 18 decimals, supply 1,000,000,000 × 10^18. It has no owner, mint, burn, pause, blacklist, fee or tax, so every launch flow in the protected floor test moves exactly what it says, and no privileged call can touch a holder's balance.
• test/SqueekToken.t.sol holds 32 tests: metadata and supply, constructor behaviour for both EOA and contract deployers, exact transfers and events, the factory to distributor to claimant flow, failure paths for balance, zero address and allowance, a sweep of eighteen admin selectors from both the deployer and a stranger, a bytecode scan for DELEGATECALL, CALLCODE and SELFDESTRUCT, the deploy script, and four fuzz tests.
• script/DeploySqueekToken.s.sol is a reviewable script whose deploy() is tested directly. The launch itself does not use it.
• README.md documents assumptions, the manifest parameters, operational responsibilities, and the security caveats.
• foundry.toml pins solc 0.8.26, sets bytecode_hash = "none", disables ffi and grants no filesystem permissions. Dependencies are vendored as ordinary files under lib/ with no git directories or submodules.

Checks run: forge build, forge test with the verifier's fuzz seed, forge test --offline under an empty environment, and forge fmt --check. All passed, 32 of 32 tests. The creation code contains no library link placeholders, and the ABI exposes only the standard ERC-20 surface plus the four public constants.

Not done, by design: no launch.json was written, and nothing was committed, since the brief leaves the commit to the submission step. The root directory holds sandbox device files such as .gitmodules and .bashrc that are not part of this work.

Done. launch.json is written and is the only changed file in the tree.

What the manifest says

• Kind custom_token, token contract SqueekToken, name Squeek, symbol SQUEEK, 18 decimals.
• constructorArgs is empty, matching the compiled ABI, which has no constructor inputs.
• totalSupply is 1,000,000,000 × 10^18 in minor units, exactly what the constructor mints to msg.sender.
• contracts is empty, since the accepted tree contains only the token and no application contracts.
• pool and economics are copied verbatim from the launch terms: IMD pair, fee 12500, tick spacing 60, one-to-one provenance price, 8000 pool bps, 1,000 IMD opening cap, remainder to the requester's address.
• Notes are about 1,500 characters and describe only SqueekToken and the launch terms.

Verification

• A script checked the manifest parses, uses only the schema's keys, and matches the required economics and pool objects.
• forge build succeeded and forge test passed all 32 tests under the verifier's fuzz seed.
• git status shows launch.json as the only addition.

The review is complete. The findings file is at the repository root with an empty findings list and nine coverage rows, and the scratch test directory has been removed.

Result: no defects in the Math Precision, Boundary or Numerical Gap areas. The token is OpenZeppelin ERC20 v5.4.0 plus three constants and a one-time mint. I diffed the five vendored files it compiles against the upstream v5.4.0 tag and they are byte-identical.

What I checked and why each entry point holds:

• Supply constant. The expression at src/SqueekToken.sol:29 evaluates to exactly 10^27, matching the manifest string in the README. The aderyn "large numeric literal" lead is a style note, not a defect.
• transfer and transferFrom. The only arithmetic is OpenZeppelin's balance subtract and add, guarded by the insufficient-balance check before the unchecked block. Zero amounts, self-transfers of the whole balance, supply plus one, and the maximum uint256 all behave as ERC-20 requires with no wrap.
• approve and allowance spending. Zero spender reverts, allowances overwrite, exactly max uint256 is infinite, max minus one decrements normally, and spending from self or from the zero address still needs an allowance.
• Boundary enumeration. There are no external calls, payable functions, receive or fallback, sentinel-address branches, bytes decoding, or narrowing casts anywhere in the token or its inherited code. Ether and unknown selectors revert.
• Numerical seams. With no division, fee, burn or mint, there is no precision loss to accumulate. A 256-run fuzz over three-hop transfers kept the sum of balances equal to total supply exactly.

Outside my area I also confirmed the launch floor expectations: the whole supply goes to the deploying contract, launch flows arrive whole with no exemption list, and no admin selector exists. The existing suite of 32 tests passes.

The review is complete and the findings file is written. The tracked tree is unchanged.

Result: no defects found. .imd-findings.json holds an empty findings list and eight coverage rows, one for each of the three state-changing entry points plus the invariants and economic properties I checked.

What I verified in the assigned area

• Economic Security. The token has no external dependencies, no oracle, no hooks, no fee, tax, reflection, blacklist, pause or max-wallet rule. Every launch leg (factory to distributor, distributor to claimant, factory to pool, pool to trader and back) moves exactly the requested amount, so nothing can arrive short or revert on the token side. Sentinel checks hold: the zero address cannot be a sender, receiver, spender or approver, even for a zero value.
• Invariant. The only mint is the constructor's single call to the deploying sender for exactly one billion tokens at 18 decimals. There is no burn path, since transfers to the zero address revert. A scratch invariant run driving transfer, transferFrom and approve across seven actors kept the sum of balances equal to the constant supply throughout. Allowance semantics are exact: finite allowances decrement by the amount moved, and max allowances stay sticky.
• Flow Gap. The token crosses no periphery boundary, has no receive or fallback, and its runtime contains no DELEGATECALL, CALLCODE or SELFDESTRUCT. There is no seam between execution, periphery and intent to exploit.

Other checks. The vendored OpenZeppelin ERC20 matches v5.4.0 upstream verbatim. The compiled ABI exposes only the three listed nonpayable functions. The project's 32 tests pass, including with a fixed fuzz seed. The aderyn large-literal lead evaluates to exactly the manifest supply and is not a defect.

By design, not reported. The standard ERC-20 approve race, where a spender front-runs an allowance change, is inherent to the requested plain token and is already disclosed in the README. I noted it in the coverage row rather than as a finding.

Not reached. The protected floor test cannot run here because Uniswap v4 core is not vendored, so the real PoolManager seed and swap were simulated with plain transfers rather than executed against the manager.

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

What I reviewed. The Access Control, Trust Gap and Asymmetry guides from the Pashov reference, applied to src/SqueekToken.sol and the OpenZeppelin base it inherits. The token is a fixed-supply ERC-20 with no constructor arguments, no owner or role of any kind, and a single constructor mint of 1e27 units to msg.sender.

What I checked and how it held up:

• Permission map. The compiled ABI exposes only the ERC-20 methods and four constant getters. There is no fallback or receive function, no initializer, no proxy, no delegatecall path, so there is no guard to be inconsistent and no role to escalate.
• Vendored base. All five dependency files compiled into the token hash identical to upstream OpenZeppelin v5.4.0, and Context returns plain msg.sender. A tampered base was the only place a hidden permission could live, and it is not there.
• Three entry points. I wrote a scratch Foundry suite of seven adversarial probes: the deployer, a stranger and the token itself cannot pull a holder's balance without allowance, approve cannot grant over another account, a failed transferFrom leaves allowance intact, transfer and self-approved transferFrom move identical amounts, the deployer is an ordinary holder once it has transferred, and fuzzed delivery to any recipient is exact. All seven passed. The scratch directory was removed afterwards since it held no proof of a defect.
• Launch floor. With no fee, exemption list or privileged selector, nothing in the token can short the factory-to-distributor, claim, seed or swap flows that the protected test checks.

Static analysis leads. Slither reported nothing. Aderyn's low-impact large-numeric-literal note on line 29 is a style remark about the supply constant and is not a defect.

Trust assumptions to record, not defects. The deployer holds the whole supply until it moves it, which at launch is the factory. The standard ERC-20 allowance race on approve exists as in every OpenZeppelin ERC-20 and the brief did not ask for permit or increase/decrease helpers.

Coverage. Eight rows in .imd-findings.json, all holds: the three entry points plus five invariants covering the absence of privileged roles, constant supply, unmodified base library, whole-arrival of launch flows, and the constructor's mint target and decimals. Nothing in my area was left unreached. No repository file other than the findings file was changed.

The findings file is in place at the repository root, excluded from git by the harness's own .git/info/exclude entry, the scratch test is removed, and the tree is otherwise unchanged.

Result: no defects found. .imd-findings.json holds an empty findings list and nine coverage rows, one for each of the three entry points and six for the invariants I checked.

What I covered in my area

• Execution Trace. Traced approve, transfer and transferFrom through the vendored ERC20 into _update, _approve and _spendAllowance. Each path reverts before any state change on zero addresses, short balance or short allowance, moves exactly the requested amount, and makes no external call. The only cross-transaction behaviour is the standard ERC-20 approve overwrite race, which the README documents as the holder's responsibility and OpenZeppelin v5 chose deliberately. I recorded it on the approve row, not as a defect.
• Periphery. The five Solidity files compiled into the token are byte-identical to upstream OpenZeppelin v5.4.0, which I cloned and diffed. The other library differences are forge fmt reformatting in files the token never imports. forge-std differs only in whitespace. No extra files sit under lib/, and no non-ASCII characters appear in the token's sources or its compiled dependencies. The deploy script only wraps a no-argument new SqueekToken().
• First Principles. The constructor is the only path with a zero from, and it mints the exact manifest supply to msg.sender. I verified this for an EOA deployer and for a CREATE2 deployment from a contract, mirroring the protected harness. An invariant fuzz across all three entry points kept the sum of balances equal to the constant supply. An opcode scan of both creation and runtime code found no CALL, STATICCALL, DELEGATECALL, CALLCODE, CREATE, CREATE2 or SELFDESTRUCT. The aderyn large-literal lead is the intended supply constant.

Not reached. The protected pool seed and swap test needs Uniswap v4 core, which this tree does not vendor, so I could not execute it locally. Since _update is not overridden and transfers move exact amounts with no exemptions, nothing in the token can tax or block the PoolManager, but that step remains the verifier's to run.

Added failure-path and fuzz tests, plus stateful invariants for supply conservation, balances, allowances, and holder spendability. Changes are confined to test/.

Validation passed: forge build and forge test — 59 tests passed, including 32,768 randomized invariant calls. No defects found.

Review complete. The audit of Squeek is clean, and .imd-findings.json holds zero findings with a full coverage record.

What the specialists reported. All four areas and the independent tester reported no findings, so there was nothing to reproduce or merge. The two static-analysis leads were a slither run with no results and an aderyn style note on the supply literal, which I checked and did not promote.

What I verified myself.

• The token in src/SqueekToken.sol is an unmodified OpenZeppelin v5.4.0 ERC20 with an argumentless constructor that mints exactly 1e27 units to msg.sender. The ABI exposes only approve, transfer and transferFrom as state-changing, with no receive or fallback.
• I read the vendored ERC20.sol and Context.sol line by line against upstream. Nothing in the transfer, allowance or sender logic is altered.
• A scratch Foundry test deployed the token through CREATE2 from a contract and confirmed the factory holds the whole supply, the distributor and claimant flows arrive whole, transferFrom cannot pull from a holder without approval, and ether or unknown selectors revert. The project's own 59 tests also pass.
• The compiled artifact has no link references and no CALL, DELEGATECALL, CALLCODE, CREATE or SELFDESTRUCT opcodes in creation or runtime code, and both are well under the size limits.
• The manifest in launch.json uses only schema keys, and its contract name, constructorArgs, decimals, totalSupply and lowercase addresses all match the source.

Coverage. All three entry points are marked holds with a one-line reason each, plus rows for the mint-once invariant, CREATE2 deployability, the vendored-library check, the manifest, and the aderyn lead. The scratch test directory was removed, so the only file written is the findings file.
