The offline clean rebuild, tests and format check all pass; the missing jq was only an inspection convenience. The work is complete and committed.

Delivered a Foundry project at the repository root for the Pepe (PEPE) custom token, committed on main as commit 84f6097.

• Token src/PepeToken.sol: contract PepeToken inherits OpenZeppelin v5.1.0 ERC20. name() is "Pepe", symbol() is "PEPE", decimals() is 18. The constructor takes no arguments and mints the full supply once to msg.sender, so at launch the factory receives it whole. There is no owner, minter, pause, blocklist, fee, upgrade path or selfdestruct, so the supply can never grow and no privileged hand can touch a holder.
• Supply in minor units is 1000000000000000000000000000, exposed as the constant INITIAL_SUPPLY.
• Tests in test/ cover metadata and supply constants, minting to an EOA deployer, to a CREATE2 factory stub and through the deploy script, exact-amount transfers and transferFroms, every OpenZeppelin failure path with its specific error, rejection of all common admin, mint, pause, freeze and seize selectors from both a stranger and the deployer, a reachable-bytecode scan for DELEGATECALL, CALLCODE and SELFDESTRUCT, five fuzz tests, and a handler-driven invariant that supply stays fixed and balances match a ghost ledger.
• Script script/DeployPepeToken.s.sol reads no environment variables. Its deploy() function is tested directly.
• Docs in README.md list assumptions, manifest-ready deployment parameters, the empty "After launch" section, operational responsibilities and the test coverage.
• Dependencies forge-std v1.9.7 and OpenZeppelin Contracts v5.1.0 are vendored under lib/ as plain files with their git metadata removed. No submodules.
• Configuration foundry.toml pins solc 0.8.26, sets bytecode_hash = "none", disables ffi and grants no filesystem permissions.

Slither is not installed here, so it did not run. The code avoids each detector the verifier rejects on, as documented in the README. Passing tests are not an audit; the README names the independent review as an open item for the launch.

The review is complete. No math defects were found, and .imd-findings.json holds an empty findings list plus eight coverage rows. The scratch test directory was removed, so the only file written is the findings file.

What was reviewed. PepeToken in src/PepeToken.sol is a 48-line wrapper over OpenZeppelin v5.1.0 ERC20 with one constructor mint and a constant decimals(). The vendored ERC20, IERC20, IERC20Metadata, Context and IERC6093 files hash byte-for-byte to upstream v5.1.0, so the three listed entry points are unmodified library code.

Math Precision pass. The only arithmetic the token adds is the compile-time constant 1_000_000_000 * 10**18. It evaluates to exactly 1e27, below 2^90, so it fits comfortably in uint96 and int128 for Uniswap v4 deltas. OpenZeppelin's unchecked balance updates are bounded by that supply. The aderyn "large numeric literal" lead at line 26 is style only. The 10% swarm and 80% pool shares divide exactly with no truncation.

Boundary pass. The token makes no external calls, has no payable, receive or fallback function, decodes no bytes and has no sentinel branches beyond the library's zero-address reverts. A scratch Foundry probe confirmed clean reverts for transfer of balance+1 and uint256 max, exact behaviour of zero-amount and self transfers, infinite allowance never decrementing, finite allowance decrementing exactly, atomic revert when allowance suffices but balance does not, and a 256-run fuzz conservation check.

Numerical Gap pass. No division, runtime multiplication, casts or accumulators exist, so no cross-lens seam is reachable.

Coverage. All three entry points are marked holds, with five extra rows for the supply constant, fixed supply, exact launch flows, boundary enumeration and seam analysis. Nothing in the assigned area was left unreached.

Review complete. The control-flow audit of PepeToken found no defects, and the findings file holds an empty list with a full coverage record.

What I checked, by guide

• Execution Trace. The three state-changing entry points, approve, transfer and transferFrom, are the unmodified OpenZeppelin v5.1.0 implementations. There are no external calls, callbacks, encoding steps, sentinel paths or multi-step operations. Zero-address sender, receiver and spender all revert. The infinite-allowance path is the documented standard behaviour.
• Periphery. I hashed every vendored OpenZeppelin file the token depends on and compared them to the upstream v5.1.0 tag. All five match byte for byte. The deploy script reads no environment and is not on the launch path.
• First Principles. The supply constant evaluates to exactly 1e27 as a uint256, confirmed by a scratch test and the existing suite. The constructor takes no arguments and mints to msg.sender, which is the factory under CREATE2. The compiled ABI exposes no mint, burn, pause, blocklist or upgrade surface, no receive or fallback, and the reachable runtime contains no DELEGATECALL, CALLCODE or SELFDESTRUCT.

Checks run

• forge build and the full suite with the verifier's fuzz seed: 38 tests passed, including the invariant suite.
• A scratch test for the supply constant and allowance sequencing, run and then deleted. The tree is unchanged apart from the findings file.

Leads dismissed

• Aderyn's large-numeric-literal note at line 26 is a style lead. The value is correct.
• The ERC-20 approve ordering property is inherent to the plain token the brief asks for, so I recorded it in the coverage row rather than as a finding.

Not reached

• The protected floor harness imports v4-core and launch helpers that are not in this tree, so I did not execute it. The project's own tests mirror its selector lists, flows and bytecode scan, and the token has no fee or exemption logic that could make the floor's flows arrive short.

The review is complete. The findings file is written at the repository root with an empty findings list and ten coverage rows, and my scratch tests are removed.

Result: no defects in the permissions area. PepeToken is OpenZeppelin 5.1.0 ERC20 plus three constants, one constructor mint and a decimals() override. There is no owner, minter, pauser, blocklist, initializer, proxy, delegatecall or selfdestruct, so the Access Control map has no roles to misuse, the Asymmetry pass has no admin variants or divergent branches, and the Trust Gap pass has no authorization-times-value seam to exploit.

What I verified:

• Compiled ABI exposes exactly the three listed nonpayable entry points and no receive or fallback.
• Vendored library files that the token inherits are byte-identical to the published OpenZeppelin 5.1.0 npm package, so the entry points are the upstream implementations.
• Permission boundaries were exercised in a scratch Foundry test, all passing: the deployer cannot pull from a holder without allowance, approve binds only the caller, allowances are spender-specific and cannot exceed balance, zero-address guards are symmetric across all three functions, unknown selectors and ETH are refused.
• Supply is fixed at 1e27 after construction. The repository's own 38 unit, fuzz and invariant tests pass.

Coverage rows: all three entry points holds, plus rows for the constructor, the no-role invariant, fixed supply, approve/transferFrom symmetry, the library match, the Trust Gap pass, and one trust assumption. That assumption is that the deployer, the ProjectFactory at launch, receives the whole supply, which the brief requires and which grants the factory nothing beyond an ordinary holder's rights.

Not reported: the standard ERC-20 approve front-running property, since it is inherent to the standard and not a defect in this implementation. Nothing in my area was left unreached.

The review is complete and the findings file is written. The working tree is clean apart from the findings file, which is untracked and reported nothing by git status --porcelain beyond itself.

Outcome: no defects in the economics area. The token is OpenZeppelin v5.1.0 ERC20 with a single constructor mint and a constant decimals(). I report one informational note and nine coverage rows in .imd-findings.json.

What I verified

• Supply conservation. One mint of exactly 1e27 to msg.sender in the constructor, no burn or mint path afterwards, and the compiled ABI exposes only approve, transfer and transferFrom as state-changing functions. No receive or fallback, so ether is rejected.
• Launch flows arrive whole. No transfer override, no fee, no exemptions. A probe splitting the supply 10/80/10 left the factory at zero and the three recipients summing to the supply. Self-transfer and infinite-allowance paths conserve exactly.
• Vendored dependency integrity. The five OpenZeppelin files on the import path are byte-identical to the upstream v5.1.0 tag.
• Static analysis lead. The aderyn "large numeric literal" at line 26 evaluates to exactly the manifest's supply string. Not a defect.
• Bytecode. Reachable runtime code uses PUSH0 and MCOPY and nothing from the forbidden set. That is fine for the README's target of chain 1, and I recorded it as a note in case the launch chain ever changes.

The one finding (info). The inherited ERC-20 approve overwrites rather than adjusts, so an owner lowering an allowance from 100 to 50 can see a front-running spender move 150. I reproduced it in a Foundry test. It is a property of the standard, not of this code, and the brief asks for a plain ERC-20, so no change is required. The project's existing 38 tests pass with the verifier's fuzz seed.

Coverage gaps. None in my area. The protected floor tests could not be run locally because they import the launch harness, which is not in this tree, but nothing in the token needs anything from it.

forge build and forge test pass with the verifier's fuzz seed: 54 tests, 0 failed. I found no defect in src/PepeToken.sol. It is a plain OpenZeppelin 5.1 ERC-20 that mints 1,000,000,000 × 10¹⁸ PEPE to the deployer once, with no owner, mint, pause or fee.

The 38 tests already in the repo were kept unchanged. I added two files under test/:

test/PepeTokenAllowanceInvariant.t.sol (invariant tests over random call sequences)

• In the earlier invariant test, every approval was spent immediately in the same call. In this handler, approvals stay in place between calls, so they can be partly spent, overwritten, set to the maximum (which is never used up) or exceeded.
• Amounts are drawn at the edges: zero, the exact holding, one more than that, the full supply, and the largest possible number.
• A separate record of the expected balances and allowances is kept by the ERC-20 rules, not by reading the token back.
• It checks after every call that:
  • the supply never changes, and the zero address and the token itself hold nothing;
  • every balance and every allowance matches the expected record, and balances add up to the supply;
  • the token accepts exactly the calls it should and refuses the rest, and a refused call changes nothing.
• An end-of-run check fails if a sequence produced no successful calls or no refusals, so the suite can't pass without testing anything.
• To check that it can fail, I ran it against a modified token that keeps 1 wei of every transfer. Two of the invariants failed, as they should.

test/PepeTokenEdges.t.sol

• Launch payout: a stand-in factory deploys the token and pays it out in one call: 10% to the distributor, a fuzzed pool share, and the remainder to the requester. Each part arrives exactly, the factory ends with nothing, and the distributor can pay all of its share on to claimants.
• Failure paths:
  • an owner calling transferFrom on its own tokens without an allowance;
  • zero-address owners and approvers;
  • spending an allowance after it was revoked;
  • a failed transferFrom leaving the allowance and balances untouched;
  • the second spend after an exact allowance is used up.
• Allowance edges: an allowance one below the maximum is still used up as it is spent; a zero-amount transferFrom needs no allowance; transferFrom emits only a Transfer event.
• Fuzz tests: transferFrom to yourself, splitting a balance between two recipients, sending more than you hold at any size, and approve moving no tokens.

One finding, info severity, in .imd-findings.json: the comment on deploy() in script/DeployPepeToken.s.sol:16 says the caller receives the whole supply. In fact the script contract receives it, as the existing deploy test asserts, and that contract has no way to send it on. run() is not affected, because the broadcasting account deploys the token there. The token itself is fine; only the comment is wrong.

The new tests are not committed.
