Implemented Squeek (SQK): 1,000,000,000 tokens with 18 decimals, minted once to the deployer. Dependencies are vendored, and deployment assumptions and responsibilities are documented in README.md.

Verified with Solidity 0.8.26:

• forge build — passed, including a clean offline build.
• forge test — 30 passed using the supplied fuzz seed.
• forge fmt --check — passed.

Protected launch integration tests require the verifier’s separate harness.

I found no defects in Squeek's access control, so .imd-findings.json has an empty findings list plus a coverage record. I changed nothing else in the repository.

What I checked: src/Squeek.sol and the OpenZeppelin v5.0.2 code it builds on in lib/, covering the Access Control, Trust Gap and Asymmetry failure modes.

• No privileged roles: the token has no owner, admin, minter, pause, blacklist, burnFrom, upgrade or forwarder logic. Its only state change outside normal ERC-20 behaviour is the one-time _mint(msg.sender, 1e27) in the constructor, so the deployer (the factory) gets the whole 1,000,000,000 SQK supply, and nothing can mint more later.
• Standard sender: _msgSender() returns plain msg.sender, with no trusted-forwarder override. approve and transfer act only on the caller's own allowance or balance. transferFrom checks and reduces the allowance before moving tokens, and an unlimited (type(uint256).max) allowance is left untouched.
• No asymmetry: there are no fees, burns or exemptions, so the transfers to the distributor, the pool seed and the swaps all move exact amounts.
• No tampering: the vendored OpenZeppelin files match standard v5.0.2. I compared them by reading the code, not by checking their hash.
• Static analysis: the only tool lead, aderyn's "large numeric literal" at src/Squeek.sol:11, is the supply constant written with underscores and is not a defect. The well-known approve front-running race is standard ERC-20 behaviour, so I did not report it.

Coverage: approve, transfer and transferFrom are all marked holds, with one extra row confirming there is no privileged role and the supply cannot grow. Nothing was left unreached.

Tests: the existing suite passes (30 of 30). I wrote no proof test because there was no finding to prove. The project's protected launch checks need launch settings this machine doesn't have, so I traced them by reading rather than running them.

I found no math defects in Squeek, so .imd-findings.json has an empty findings list and four coverage rows, all marked holds.

What the code is: src/Squeek.sol is 16 lines. It mints 1_000_000_000 * 10 ** 18 (exactly 1e27) to the deployer once, in the constructor. Everything else is the unmodified OpenZeppelin v5.0.2 ERC20 the project includes. The token has no division, rounding, scaling, downcasts, external calls, payable functions, bytes decoding or address-sentinel branches. So most items in the Math Precision and Boundary guides have nothing to apply to, and the Numerical Gap guide has no pair of precision, invariant and boundary concerns to combine.

What I checked:

• Unchecked arithmetic in OpenZeppelin's code:
  • The balance subtraction only runs after the fromBalance < value check reverts on an overdraw.
  • The allowance subtraction only runs after the currentAllowance < value check.
  • Adding to a recipient's balance can't overflow, because all balances add up to the fixed 1e27 supply and no mint or burn is possible after deployment.
• Edge inputs, in a scratch test that passed and was then deleted:
  • Transfers of 0, of the full supply, and of the balance + 1 (reverts).
  • A self-transfer, and a transfer to address(0) (reverts).
  • An allowance of type(uint256).max stays unchanged when spent.
  • An exact allowance drops to 0 after use, and the next 1-wei spend reverts.
  • transferFrom for 0 works with no allowance.
  • A fuzz test showed the total of all balances stays at 1e27.
• Existing tests: 32 passed, 0 failed, including the invariant suite (128 runs, 8,192 calls).
• Aderyn's "large numeric literal" warning: a style flag only. The value is computed when the contract is compiled, and the test confirmed it equals exactly 1e27 with decimals() == 18.

I didn't run the protected launch tests, because they import harness files (floor/, src/LaunchLiquidity.sol) that aren't in this tree.

The tree has untracked files I didn't create: .bashrc, .profile, .zshrc, .gitconfig, .mcp.json, .claude/, .vscode, .idea and .gitmodules. I didn't open or change them. Check them before anything is packaged from this directory, since a submission that includes configuration files is rejected.

I found no defects in the economics of Squeek (SQK). .imd-findings.json contains an empty findings list and a coverage row for each of the three entry points, plus three invariant rows. Nothing in the tree was changed: the one test I wrote under test/scratch/ was deleted after it ran.

The code: src/Squeek.sol is a plain OpenZeppelin v5.0.2 ERC-20. The constructor takes no arguments and mints 10^27 units (1 billion × 10^18) once to whoever deploys it. There is no owner, no fee or burn on transfer, and no pause, blacklist, mint or burn function. The compiled ABI matches: the only functions that change state are approve, transfer and transferFrom.

Checks I ran:

• Library is unmodified: I downloaded the OpenZeppelin v5.0.2 archive; its SHA-256 matches DEPENDENCIES.json. All six vendored files are byte-identical to it.
• Economic Security guide:
  • Transfers move exactly the amount sent, with no fee or rebase, so a pool balance check reads exactly what arrived.
  • The token calls no outside contract, oracle or price feed.
  • Nobody holds a special role that could take or freeze balances.
  • The ERC-20 behaviour is standard: an unlimited allowance never decreases, and calls with zero amounts or zero addresses behave as OpenZeppelin defines.
• Invariant guide:
  • The total supply stays fixed and equals the sum of all balances, because minting happens only in the constructor and nothing can burn.
  • A finite allowance drops by exactly the amount spent.
  • A failed call (low balance or low allowance) reverts and changes nothing.
  • The repo's 30 tests, including the invariant suite, all passed.
• Flow Gap guide: I ran a 512-run fuzz test of the launch flow:
  • A stand-in factory deploys the token via CREATE2 and holds the whole supply.
  • It sends 10% to a distributor address, 80% to a pool-manager address and the rest to the remainder address.
  • A trader buys from and sells back to the pool address.
  • Every balance change was exact and the supply never changed. It passed.
• Static analysis: the one tool hit (a "large numeric literal" at line 11) is the supply constant, which is correct as written, so I didn't report it.

What I couldn't cover:

• Protected integration tests: the repo doesn't include the launch harness or Uniswap v4 code they need, so I couldn't run them. The real pool seed and swaps are untested here; my fuzz test only used plain addresses in place of the pool manager and distributor.
• Manifest: there is no launch.json yet, so it wasn't reviewed.

The README already documents the usual ERC-20 limits: the approval race, and tokens sent to the contract itself being stuck. I didn't count these as defects.

Created launch.json matching Squeek’s constructor, supply, and required pool/economics values.

forge build passed. All 30 repository tests passed with the supplied fuzz seed. Only launch.json is changed for submission.

The review is complete. The findings file is written and the tree holds no other changes.

Result: no defects found in Squeek. The file .imd-findings.json holds an empty findings list and seven coverage rows, all holds.

What I checked, against the Execution Trace, Periphery and First Principles guides:

• Execution flow. Each of the three state-changing entry points was traced through the vendored OpenZeppelin v5.0.2 code to its storage writes and revert paths. Zero-address sender, receiver and spender all revert. Insufficient balance or allowance reverts atomically, with the allowance rolled back. Finite allowances decrement, the maximum stays sticky, and a spender equal to the owner still needs allowance. Every transfer moves its exact amount with no fee, callback or exemption logic, so the launch flows arrive whole.
• Periphery. I downloaded the upstream v5.0.2 archive. Its hash matches the one recorded in DEPENDENCIES.json, and all five vendored Solidity files plus the license are byte-identical to upstream. No base-contract logic was altered.
• First principles and deployment. The constructor takes no arguments, is nonpayable, makes no external call, and mints exactly 10^27 units to its immediate deployer under both CREATE and CREATE2. The compiled ABI exposes no mint, burn, admin, initialize, upgrade, receive or fallback surface. Disassembly of the runtime shows no CALL-family or SELFDESTRUCT opcodes. Metadata hash is none and decimals return 18, matching the README.
• Static-analysis lead. The aderyn large-literal note is a compile-time constant that evaluates to exactly the stated supply, so it is not a defect.

The existing suite of 30 tests passed with the README's seed. Ten additional scratch probes covering constructor reentrancy, value rejection, allowance boundaries, stranded transfers and fuzzed round-trips all passed and were removed afterwards. The one behaviour worth noting as a trust assumption rather than a defect is the standard ERC-20 approve race, which the README already documents.

Added 17 boundary and failure-path tests, and expanded invariants to mix successful and rejected operations across four actors.

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

Only test/ changed. No implementation defects found.

I found no defects in Squeek, so the findings list in .imd-findings.json is empty. All four specialists and the test writer also reported nothing, so there was nothing to reproduce or merge.

• The contract: src/Squeek.sol is a plain OpenZeppelin ERC-20. Its constructor mints 1_000_000_000 * 10 ** 18 once to the deployer, and nothing else can mint. It has no owner, no admin functions, no transfer fee or burn, and it doesn't override any ERC-20 functions. That means transfers to the distributor, seeding the pool and swaps all move exactly the amount stated.
• Coverage: I traced each of the three entry points and marked them holds: approve, transfer and transferFrom. I added a fourth row for the fixed-supply invariant.
• The manifest: launch.json matches the contract. The supply is 1000000000000000000000000000, decimals are 18, constructorArgs is empty to match the constructor, there are no application contracts, and the contract name is short enough. It uses only keys from the schema.
• Static analysis: slither reported nothing. aderyn's one line, "large numeric literal" at src/Squeek.sol:11, is about how the supply constant is written, not a defect, so I didn't report it.

I didn't run the protected test suite. I read the contract and checked it by hand, and the review changes no files.
