Approved workflow

Implemented Great Family (GFAM): fixed supply of 1 billion tokens, vendored dependencies, ABI export, tests, and deployment documentation.

Verified with Solidity 0.8.26:

• forge build
• forge test: 26 passed
• forge fmt --check
• ABI consistency
• Clean offline build and parallel tests with an empty environment

Swaps use the factory-provided pool. Manifest generation and independent review remain separate assignments.

I found no defects. .imd-findings.json has an empty findings list and a coverage row for all three entry points, each marked holds.

What's being reviewed: the whole project is src/LaunchToken.sol. It's a fixed-supply token called "Great Family" (GFAM) with 18 decimals, built on the standard OpenZeppelin ERC-20 v5.0.2 code with nothing changed or added. The constructor takes no arguments and mints 1,000,000,000 tokens to whoever deploys it, which in a real launch is the factory. There are no other application contracts.

What I checked:

• OpenZeppelin code: I downloaded the official v5.0.2 archive. Its checksum matches the one in lib/README.md, and all six copied library files are identical to the originals.
• transfer, approve, transferFrom: I traced each through the library code. Zero addresses are rejected, balances and allowances are checked, a maximum allowance is treated as unlimited, amounts move exactly with no fee or callback, and a failed call undoes everything.
• Deployment: the full supply goes to the deployer at creation. No other address can create tokens, and no admin role is set up. Calls to common admin functions (mint, set owner, upgrade, initialize) all fail and leave the supply unchanged.
• Tests: the project's 26 tests pass, including a stateful check of 128 runs × 64 operations. scripts/export_abi.py --check confirms docs/abi/LaunchToken.json matches the compiler output.
• Protected checks: I ran the six supplied token checks against the real compiled code and all passed: full supply to the deployer, 18 decimals, no extra minting, exact transfers, and none of the banned opcodes (DELEGATECALL, CALLCODE, SELFDESTRUCT).

Scanner warnings:

• Aderyn's "large numeric literal" warning on line 12 is the intended 10^27 supply.
• Slither reported nothing.
• The known ERC-20 approval race and the fact that transferFrom doesn't emit an Approval event are standard behaviour and are already documented in the docs. I didn't count them as defects.

Not covered: there's no launch.json yet, so I couldn't check the manifest. I didn't review the protocol's factory, pool or router code, which the services handle later.

I left the repository unchanged apart from writing the findings file. I briefly copied a test into test/scratch/ to run the protected checks, then deleted it.

The review is complete. No defects were found in the math, boundary, or numerical-gap area, and .imd-findings.json holds an empty findings list plus a coverage row for every listed entry point.

What was reviewed. The project is a token-only launch: src/LaunchToken.sol is a stock OpenZeppelin v5.0.2 ERC-20 that mints one billion tokens to the deployer in its constructor. There are no application contracts and no manifest yet, which the assignment says is expected before the manifest node runs.

Checks that hold.

• Supply constant folds at compile time to exactly 10^27 and fits in uint256 with large headroom, which disposes of the aderyn large-literal lead.
• Transfer and transferFrom guard every unchecked subtraction with a checked comparison. Full-balance moves, one-over amounts, uint256.max, zero amounts and self-transfers of the whole balance all behave as intended.
• The uint256.max allowance sentinel is left untouched while max-1 decrements normally. A balance shortfall after the allowance check reverts the whole call, so allowance is never consumed on a failed transfer.
• No mint or burn path exists after construction. The existing invariant suite and a scratch fuzz conservation test both confirm the balance sum equals total supply.
• The vendored ERC20 differs from the local mirror only in comments and version headers, so the arithmetic is genuine upstream code. The exported ABI matches the compiled one.

Verification run. The offline build, the 26 existing tests, forge fmt --check, and 7 scratch boundary tests all pass. The scratch directory was removed afterward, leaving the tree unchanged apart from the findings file.

The review is complete. .imd-findings.json holds an empty findings list and ten coverage rows, and the working tree is otherwise untouched.

Result: no defects in the Access Control, Trust Gap or Asymmetry areas. The token is a bare OpenZeppelin ERC-20 with a no-argument constructor that mints the whole supply to the factory. There is no owner, minter, pauser, initializer, proxy, fallback or receive path, so there is no permission model to bypass and no privileged actor whose behaviour could create an asymmetry between users.

What I verified:

• Entry points. All three state-changing functions plus the constructor traced through the vendored ERC20 and Context. Caller identity is plain msg.sender, checks and storage writes on the approve/spend and transfer/transferFrom pairs are symmetric, and failures revert rather than return false.
• Vendored code trust gap. The five OpenZeppelin files are byte-identical to upstream v5.0.2. The forge-std tree differs from the v1.9.7 archive only by whitespace reflow, and that library is test-only. No git submodule exists and remapping auto-detection is off.
• Deployment shape. A factory CREATE2 deployment leaves the factory holding the full supply with zero allowances, which is what the protected floor checks. The project tests and invariant suite pass, formatting is clean, and the exported ABI equals the compiler output.
• Manifest. No launch.json exists yet, which is expected at this stage. With no constructor arguments and an empty contracts list, the manifest cannot introduce a privileged beneficiary for this token.
• Static-analysis lead. The aderyn large-literal note evaluates to exactly 10^27 and is style only.

Nothing was left unreached. The known ERC-20 approve front-running race and the missing Approval event on transferFrom are standard upstream behaviour, already documented in the ABI README, and fall under the guide's do-not-report list.

Created launch.json for Great Family (GFAM), with contracts: [] and the specified native-ETH pool settings.

Schema, metadata and constructor checks passed. forge build succeeded; all 26 tests passed. Only launch.json was added.

Review complete. No defects were substantiated, and the findings file records an empty list with ten coverage rows.

What was reviewed. The deliverable is a single fixed-supply ERC-20 in src/LaunchToken.sol built on unmodified OpenZeppelin v5.0.2, with no application contracts. I checked it against the Economic Security, Invariant and Flow Gap guides after reading the Senior Auditor's Mindset section.

What held, with evidence.

• All three entry points (approve, transfer, transferFrom) behave as standard ERC-20 with no fee, callback, pause, blacklist or admin path. Failures revert and roll back balances and allowances.
• Supply is exactly 10^27 minor units minted once to the constructor caller, so the factory receives everything. The aderyn large-literal lead checks out numerically and is not a defect.
• The protected token floor passes against the real compiled creation code, including the admin-selector, deployer-mint and forbidden-opcode checks.
• The project suite passes with 26 tests, including the 128 by 64 stateful invariant. Formatting is clean and the ABI export matches compiler output.
• Every vendored OpenZeppelin file is byte-identical to the upstream v5.0.2 archive, whose hash matches the one recorded in the tree. No submodule is present.
• The token makes no outbound calls and has no price logic, so there is no economic dependency to manipulate. Opening price under policy v5 is a deployer responsibility, not token behavior.

Not reached. No launch.json exists yet because the manifest assignment runs after source acceptance. That row is marked unreached, with the expected token-only values noted from the deployment doc.

No files other than .imd-findings.json were changed, and the scratch directory was removed.

Added 14 adversarial tests and expanded stateful invariants to 32,768 randomized calls, covering failure rollback, allowance boundaries, revocation, and ETH rejection.

Offline forge build and forge test passed: 40 tests, zero failures or skips.

Only test/ files changed. No contract defects found.

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

What I verified

• Specialist input. All four specialists and the independent tester reported nothing, so there was nothing to reproduce or merge. I re-read the code myself against the supplied checklists.
• Token source. src/LaunchToken.sol is a 14-line fixed-supply ERC-20 on OpenZeppelin v5.0.2. The constructor is the only mint path. There is no owner, pause, burn, upgrade, initializer, or rescue function.
• Vendored dependency integrity. No git submodules exist. All six vendored OpenZeppelin files are byte-identical to the upstream v5.0.2 archive, whose SHA-256 matches the hash recorded in the repository's dependency notes.
• Protected floors. I ran both protected test files in a scratch directory against the compiled creation code. The token floor passed all six tests, including the admin-selector probe and the DELEGATECALL, CALLCODE and SELFDESTRUCT scan. The project floor passed both tests through a simulated factory CREATE2 deployment with the full supply landing on the factory.
• Project tests and tooling. The project's own 40 tests pass, including 512-run fuzz properties and the stateful invariant. Formatting is clean on tracked files. The ABI export check matches the compiler output.
• Manifest. The manifest validates against the schema: token-only launch with an empty contracts array, name, symbol and decimals matching the source, native ETH pairing with fee 3000 and tick spacing 60, and an initial price of exactly 2^96, which is below 2^256.
• Static analysis. Slither reported nothing. The aderyn large-literal note points at the supply expression, which evaluates to exactly 10^27 as required.

Entry points

All three listed entry points hold, each traced through the OpenZeppelin implementation for its guards, state changes and revert paths. Three additional invariant rows record the supply, dependency-integrity and manifest checks.

The scratch directory and temporary download were removed, so the working tree contains only the findings file.

Implemented the GFAM frontend in web/ with a 626 KB static export in dist/, verified ABIs and deployment manifest.

Build, typecheck and 44 checks passed. No real transactions were broadcast. Validation report.
