Implemented Forever Cult Fund (FOREVER): 1 billion tokens, 18 decimals, minted once to the deployer.

Included offline dependencies, deployment documentation, and success/failure tests.

Passed with Solidity 0.8.26:

• forge build
• Seeded forge test: 32 unit/fuzz tests plus both stateful invariants
• forge fmt --check

I found no defects, and .imd-findings.json contains an empty findings list.

What the token is: src/ForeverToken.sol is a standard OpenZeppelin ERC20 with nothing changed. It has no overrides, hooks, fees, burns, owner, pause, or mint/burn functions. The constructor mints exactly 1e27 (1,000,000,000 tokens with 18 decimals) once, to msg.sender.

What I checked:

• Execution trace: I followed transfer and transferFrom through OpenZeppelin's internal transfer and balance-update code. They move the exact amount and make no outside calls, so there is no reentrancy risk. They revert as a whole on a zero address, a short balance or a short allowance. An unlimited approval is never reduced.
• Periphery: The token makes no outside calls and has no callbacks or oracles. Transfers from the factory, the pool manager and the distributor all arrive in full, which is what the launch requires.
• First principles: The total supply can never change after deployment, and no address has special powers.
• Static-analysis lead: The aderyn "large numeric literal" warning at line 10 is just the supply constant written out, and the value is correct.
• Tests: The project's existing suite passes (33 tests).

Coverage record: The file marks all three listed entry points (approve, transfer, transferFrom) as holds, plus a fixed-supply row. Nothing was left unreached.

Created launch.json matching ForeverToken, with no constructor arguments or application contracts, the exact supply, and the required economics and pool settings.

forge build succeeded. forge test passed all 33 tests using the supplied fuzz seed. Only launch.json changed.

The review is complete and found no defects. The findings file holds an empty findings list and a full coverage record.

What was reviewed. The deliverable is a single 16-line contract, ForeverToken, which inherits OpenZeppelin v5.1.0 ERC20 unchanged and mints the whole supply to the deployer in its constructor. I checked it against the Access Control, Asymmetry and Trust Gap guides from the Pashov reference plus the Senior Auditor's Mindset, and against the protected launch floor tests.

Why it holds in my area.

• Access control: there is no owner, minter, pauser, initializer, proxy or settable parameter. The compiled ABI exposes only approve, transfer and transferFrom as state-changing functions. The constructor hands out no role; it mints 10^27 units to msg.sender, which is the factory under the launch's CREATE2 path.
• Asymmetry: transfer and transferFrom share the same debit and credit path. The only extra write in transferFrom is the allowance decrement, skipped only for the max-uint sentinel, which is documented standard behaviour.
• Trust gap: with no privileged actor, no fee, no exemption list and no formula, every caller class executes identical code, so no seam between authorization, economics and asymmetry exists.

Verification performed.

• The five vendored OpenZeppelin files are byte-identical to the upstream v5.1.0 tag. I fetched them and compared SHA-256 hashes rather than trusting the repository's own dependencies.json.
• A linear opcode scan of the runtime bytecode found no CALL, DELEGATECALL, CALLCODE, CREATE or SELFDESTRUCT.
• The existing 33 tests, including the 256-run stateful invariant suite, pass with the README's seed.
• The aderyn large-numeric-literal lead is a style note. The constant evaluates to exactly 10^27, matching the brief.

Not in scope and not needed. No launch.json exists in the tree, which is expected before the manifest step. The standard ERC-20 allowance replacement race is inherent to the specification, is documented in the README, and is not a defect of this code, so I did not report it.

The working tree is unchanged apart from the findings file. Nothing was left under test/scratch, and the temporary fetch directory outside the repository was removed.

The review is complete. .imd-findings.json holds zero findings and eight coverage rows, and the working tree is otherwise unchanged (the findings file is gitignored, so git status is clean).

Outcome: no defects found in the Economic Security, Invariant or Flow Gap areas.

What the token is. src/ForeverToken.sol is 16 lines: it inherits OpenZeppelin v5.1.0 ERC20, sets the name and symbol, and mints 10^27 units to msg.sender once in the constructor. The compiled ABI has only the nine standard ERC-20 methods plus the INITIAL_SUPPLY constant. There is no owner, mint, burn, pause, blacklist, hook, callback, receive or fallback.

What I verified, and how:

• Library integrity. I downloaded the upstream OpenZeppelin v5.1.0 archive and compared all five vendored files byte for byte. They are identical, so _update, _approve and _spendAllowance are the audited upstream code.
• Supply conservation. The only _mint is in the constructor. Sum of balances equals total supply by construction of _update, confirmed by the project's 256-run stateful invariant and my own flow test.
• Launch flows exact. A CREATE2 factory receives the whole supply. The 10 percent to a distributor, the distributor's claim, a v4-style pull by approve plus transferFrom, the push to a trader, and the sell-back all move exactly the requested amount with no fee, tax or burn.
• Boundaries and sentinels. Transferring the whole supply works; one wei more reverts atomically. Transfers, approvals and transferFrom involving the zero address revert with ERC-6093 errors. The token's own address is an ordinary sink. Direct ETH sends revert.
• Forbidden opcodes. The same reachable-opcode scan the protected floor uses finds no DELEGATECALL, CALLCODE or SELFDESTRUCT in the runtime, which is well under the EIP-170 limit.
• Decimals. The OZ default returns 18, matching the brief.

Static analysis leads. Slither reported nothing. Aderyn's single low-impact "large numeric literal" at line 10 is the supply constant 1_000_000_000 * 10 ** 18, which equals the manifest's 10^27 exactly. Not a defect.

Trust assumptions and notes for the judge. The standard ERC-20 approve replace-race exists, as in every OZ token, and the README documents it; I did not report it because it is inherent to the specification the requester asked for. The one item outside the token's control is that msg.sender must be the factory at deployment, which the launch path guarantees and the protected floor re-checks.

Coverage. All three listed entry points are marked holds, plus five invariant and dependency rows. Nothing in my area was left unreached.

The review is complete and .imd-findings.json is written. No tracked file changed.

Result: the math holds. The token's only arithmetic is the compile-time constant 1_000_000_000 * 10 ** 18 in src/ForeverToken.sol:10, which equals exactly 10^27, the manifest's minor units, and is minted once in the constructor. Everything else is unmodified OpenZeppelin v5.1.0 ERC20, whose six vendored files match their recorded hashes.

What I checked against the three guides

• Math Precision: no division, no fixed-point conversion, no downcasts, no decimal mixing. The unchecked balance additions in OpenZeppelin cannot wrap because the sum of balances equals a fixed 10^27 supply with no mint or burn path after construction.
• Boundary: the token makes no external calls, has no receive or fallback, decodes no bytes, and the only zero-address branches are OpenZeppelin's guards, which revert on every public path. I probed 1 wei, exact balance, balance plus one, max uint, self-transfer, self-transferFrom at exact allowance, max and max-minus-one allowances, and ETH sends with and without calldata.
• Numerical Gap: the launch's 10/80/10 split of 10^27 is exact with no dust, and the conservation invariant holds to the wei under the project's stateful invariant suite plus a fresh fuzz run.

All of these ran as a scratch test under test/scratch/, 10 passing probes, which are not submitted.

One finding, informational and outside the math area. Seven forge-std files under lib/ do not match the SHA-256 hashes recorded in lib/dependencies.json, while the README claims every vendored file was verified. forge-std is test-only, so there is no on-chain impact. The finding gives the exact recorded and actual hashes for reproduction. The aderyn large-numeric-literal lead is style only and is recorded as holds.

Coverage: all three entry points (approve, transfer, transferFrom) are holds, plus five invariant and boundary rows. Nothing was left unreached.

Added 13 boundary/fuzz tests and expanded invariants to cover rejected calls, allowance rollback, supply conservation, and full-balance transfers.

forge build and seeded forge test pass: 46 tests, including 32,768 invariant calls. No defects found. Only test/ files changed.

The review is complete and .imd-findings.json holds the result. The working tree is clean apart from the gitignored findings file.

Outcome: no defects in the token. ForeverToken is OpenZeppelin v5.1.0 ERC20 with a parameterless constructor that mints 10^27 units to the deployer once. I built it, ran the project's 46 tests, and ran my own scratch test exercising approve, transfer and transferFrom including revert paths, unlimited allowance, and probes for mint, burn, owner and ETH receive. All three entry points hold. The ABI exposes no privileged function, the runtime has no DELEGATECALL or SELFDESTRUCT, and both size limits are met. The vendored ERC20.sol matches upstream v5.1.0 byte for byte.

One finding kept, at info severity. The audit_math specialist's report reproduces: seven vendored forge-std files do not match the hashes in lib/dependencies.json. I traced the root cause further than the specialist did. The recorded hashes are the correct upstream v1.9.7 hashes, so the vendored copies were altered, and stripping whitespace shows the only change is line wrapping from forge fmt running over lib/. There is no semantic change and no effect on deployed bytecode. The defect is that the README's provenance claim is false. The fix is to re-vendor the exact files and exclude lib/ from formatting, or regenerate the seven hashes.

Manifest checked. launch.json uses only schema keys, the contract name and constructor arguments match the code, totalSupply equals what the constructor mints, addresses are lowercase, and economics match the reference values for this launch.

Coverage record: all three listed entry points marked holds, plus rows for the supply invariant and the manifest.
