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

Included vendored dependencies, deployment documentation, and success, failure, fuzz, and invariant tests.

Verified with Solidity 0.8.26:

• forge build passed.
• forge test passed: 29 tests using the required seed.
• forge fmt --check passed.

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

forge build succeeded; all 29 local tests passed with the supplied fuzz seed. Only launch.json is changed for submission.

The review is complete and the findings file is written. No defects were found in the assigned area.

Result: .imd-findings.json holds an empty findings list and nine coverage rows, one for each of the three listed entry points plus six invariant and boundary rows.

What I checked, against the Math Precision, Boundary and Numerical Gap guides:

• The token is src/GoatPro.sol, a plain OpenZeppelin ERC20 with one constructor mint and no other code. The five vendored OpenZeppelin files hash-match upstream v5.0.2 byte for byte, so the unchecked arithmetic in _update rests on upstream's proven bounds.
• The supply literal evaluates to exactly 10^27, matching the README and manifest figure, and decimals is the literal 18. This resolves the aderyn large-literal lead as not a defect.
• The launch shares of 10%, 80%, 2% and 8% divide 10^27 with zero remainder and sum back exactly. Transfers carry no fee, burn or rounding, so the distributor, pool and remainder flows arrive whole.
• Boundary cases were exercised in a scratch test under test/scratch: full balance, one wei over balance, max uint, zero value, self-transfer, allowance one wei short, max and max-minus-one allowance, native value with and without calldata, and mint/burn selectors. All behave as intended. A 512-run fuzz confirmed conservation of supply.
• There are no external calls, no payable functions, no bytes decoding and no division, so no numerical-gap seam can open.

One behaviour worth knowing, not a defect: anyone can call transferFrom with value 0 on any holder without an allowance. It moves nothing and emits a zero-value Transfer event. This is standard ERC-20 behaviour and the project's own test suite documents it as intended.

No tracked source, config or library file was changed. The scratch test file is in the directory reserved for it and is not kept.

The review is complete. The findings file holds an empty finding list and nine coverage rows.

Result: no defects found. GoatPro is a 17-line wrapper over OpenZeppelin ERC-20 v5.0.2 that mints the full supply once to the deployer in the constructor and adds nothing else.

What I verified, in my area (Execution Trace, Periphery, First Principles):

• All three entry points hold. I traced approve, transfer and transferFrom through the inherited code. Zero-address sender and receiver revert, insufficient balance or allowance reverts atomically with allowance restored, the unlimited allowance is not decremented, and finite residuals are exact under fuzzing. A transferFrom with a zero sender cannot mint.
• Constructor and initial state hold. The supply is exactly 10^27 base units, credited to msg.sender, so a CREATE2 deploy through the factory credits the factory and not the wallet that called it. Decimals, name and symbol match the brief.
• No privileged surface exists. The compiled ABI exposes only the ten standard ERC-20 selectors. All 22 privileged selectors the protected harness probes revert from both the factory and a stranger. There is no receive or fallback, so empty-calldata and ETH calls revert.
• Runtime bytecode is clean. An opcode scan of the deployed code finds no DELEGATECALL, CALLCODE, SELFDESTRUCT, CALL or STATICCALL, and the size is well under the EIP-170 limit.
• Periphery is genuine. I downloaded the five vendored OpenZeppelin files from the published 5.0.2 package and they are byte-identical to the copies under lib/.
• Launch flows move exact amounts. A scratch test reproduced the distributor share, pool seed and remainder leaving the factory whole, a whole claim, and transfers to and from the pool address in both directions.

The project's own 29 tests and format check pass. The aderyn large-literal lead is a style note only, since the literal evaluates to the intended supply. The scratch test and temp download directory have been removed, so no tracked file was changed.

The review is complete. The findings file is written and validated, and the working tree holds no changes other than it.

Result: no defects in the assigned area. GoatPro is a 17-line wrapper over OpenZeppelin v5.0.2 ERC20 with one constructor mint. The Access Control, Trust Gap and Asymmetry checklists found nothing to fix.

What I verified:

• Permission model is empty by design. There is no owner, role, initializer, proxy, mint, burn, pause, blocklist, receive or fallback path. The compiled ABI is exactly the ERC-20 surface plus the INITIAL_SUPPLY constant.
• Constructor roles. The whole supply mints once to msg.sender, which is the factory under a CREATE2 launch. A fixture confirmed the factory's caller receives nothing and the deployer keeps no power over holders afterwards.
• Asymmetry pairs. The transfer and transferFrom paths share one debit routine with no branches, fees or exemptions. The approve and allowance-spend pair behaves as upstream documents, including the unlimited-allowance case.
• Dependency integrity. All five vendored OpenZeppelin files diffed byte-identical to the upstream v5.0.2 tag, so no trust gap hides in the library.
• Bytecode. The runtime contains no DELEGATECALL, CALLCODE, SELFDESTRUCT, CALL, STATICCALL or CREATE opcodes, so the protected floor's opcode test will pass.
• Existing suite. All 29 project tests pass, including the stateful invariant run.

The one entry in the file is informational. It records the standard ERC-20 approve-overwrite race with a concrete front-run sequence. It is inherent to the standard the requester asked for and is already documented in the README, so it needs no code change.

Coverage rows answer all three listed entry points as holding, plus six invariant rows covering the constructor, supply growth, privileged calls, launch flows, forbidden opcodes and dependency integrity. The scratch test directory was removed after use.

Review complete. The findings file is written and no repository files were changed.

Result: no defects found. GoatPro is a 17-line contract that inherits the vendored OpenZeppelin v5.0.2 ERC20 and does one thing: mint 1,000,000,000 GPRO with 18 decimals to the deployer in its constructor. I checked it against the Economic Security, Invariant and Flow Gap guides and could not substantiate a single failing input.

What I verified:

• Supply invariant. The constructor's single mint equals the manifest value exactly. The compiled ABI exposes only the ten standard ERC-20 functions plus the supply constant. Mint, issue, owner, initialize, receive and fallback probes all revert.
• Flow exactness. Transfers from a CREATE2 factory to a distributor, a pool address and a remainder address sum to the whole supply with no shortfall, and the factory cannot overdraw by one wei afterward.
• No privileged power. There is no owner, pause, blacklist or seize path. The factory cannot pull a holder's balance without an approval.
• Dependency integrity. I downloaded the upstream v5.0.2 archive, confirmed its checksum matches the one in DEPENDENCIES.md, and found all five vendored files byte-identical.
• Runtime. An opcode scan found no DELEGATECALL, CALLCODE, SELFDESTRUCT or external call opcodes.
• Tests. The project's 29 tests pass, including the fuzz and invariant suites. My four scratch tests also passed and were removed. One early fuzz failure was my own test double-counting the test contract as a recipient, not a token defect.

The aderyn large-numeric-literal lead is a style note only. The literal evaluates to the correct supply. The one piece I could not reach is the protected Uniswap v4 seed-and-swap harness, which needs the verifier's launch infrastructure. A plain OpenZeppelin ERC20 has no transfer hook that could interfere with it.

The coverage record has ten rows: the three entry points plus seven invariants, all marked as holding.

Added 18 tests covering failure paths, allowance boundaries, and rollback. Expanded invariants to exercise invalid calls, balance conservation, and holder transfers.

Validation passed: forge build --offline and all 47 tests with the required seed, including 32,768 invariant calls.

Only test/ files changed. No implementation defects found.

I found no defects in GoatPro, so .imd-findings.json has an empty findings list plus coverage rows. No other file in the tree was changed.

The specialist finding: only the permissions specialist reported anything: the approve-overwrite race, rated info. I dropped it. It's true that a spender can front-run a change of allowance and spend both the old and new amounts. But every ERC-20 behaves this way by design, so it isn't a defect in this code. The README already tells holders to revoke an allowance and wait for confirmation before granting a new one. There was nothing to merge, since no other specialist reported anything.

What I checked myself:

• Contract: src/GoatPro.sol inherits OpenZeppelin v5 ERC20 and overrides nothing. The constructor runs _mint(msg.sender, INITIAL_SUPPLY) once, for 1,000,000,000 tokens at 18 decimals.
• No privileged powers: there is no owner, role, further mint, burn, pause, blocklist, receive or fallback.
• Library code: I read the vendored _update, _approve and _spendAllowance and they are standard. Transfers move exactly the amount asked, with no fee or burn. That means the launch steps arrive in full: the factory paying the distributor, seeding the pool, and the PoolManager's transferFrom during settlement.
• Static analysis: aderyn's only line, a "large numeric literal" at line 10, is the supply constant written with digit separators. It's not a defect.
• Manifest: launch.json matches the code and the schema. It has empty constructorArgs for the zero-argument constructor, totalSupply of 1000000000000000000000000000, decimals 18, and only schema keys.
• Build and tests: forge build succeeds and forge test passes all 47 tests in the 3 suites.

Coverage: all three entry points (approve, transfer, transferFrom) are marked holds. A fourth row records that the supply is fixed and minted once to the deployer.

I couldn't run the protected floor tests, because the harness files they import aren't in this tree.
