Implemented ADAM: 1,000,000,000 tokens, 18 decimals, minted once entirely to the deployer.

Vendored dependencies and documented assumptions, deployment parameters, and responsibilities in README.md.

Verified with Solidity 0.8.26:

• forge build passed
• forge test passed: 30 tests, including fuzz and invariant checks
• forge fmt --check passed

Taylor, the review is done. No defects found in the math, boundary, or numerical-gap area. .imd-findings.json holds an empty findings list and seven coverage rows, and no source files were changed.

What I checked

• Supply constant. The literal flagged by aderyn folds to exactly 10^27 with zero remainder against 18 decimals. It is minted once in the constructor and no mint, burn or rebase entry point exists.
• transfer and transferFrom arithmetic. Both unchecked blocks in the vendored OpenZeppelin _update and _spendAllowance sit behind an explicit bound check. I probed zero, full supply, supply plus one, max uint, self-transfer at full balance, and the infinite-allowance sentinel edge (max is infinite, max minus one is finite).
• approve. Plain overwrite, zero-spender revert, no arithmetic.
• Boundaries. No external calls, no payable surface, no receive or fallback, no bytes decoding. Ether sends and unknown selectors revert.
• Dependency integrity. All six vendored OpenZeppelin files hash-match both DEPENDENCIES.json and the upstream v5.1.0 commit.

Evidence

The three listed entry points are all marked holds. Nothing in the assigned area was left unreached.

Created launch.json matching ADAM’s constructor, exact supply, and verbatim economics.

Schema and constructor ABI checks passed. forge build succeeded; forge test passed all 30 tests. Only launch.json is changed outside scratch artifacts.

The review is complete. The findings file is written and valid, the scratch test is removed, and the working tree has no stray files.

Result: no defects found. .imd-findings.json holds an empty findings list and ten coverage rows, all holds.

What was reviewed

• src/ADAM.sol is a 15-line contract: canonical OpenZeppelin v5.1.0 ERC20 plus a constructor that mints one billion tokens with 18 decimals to the deployer. It has no owner, mint, burn, pause, blacklist, tax, hooks, proxy or external calls.
• The three state-changing entry points were traced through the Execution Trace, Periphery and First Principles guides. Every guard sits before every write, there is no stale read, no partial update, no sentinel path that skips validation, and the max-allowance behaviour is standard and documented.
• The vendored OpenZeppelin files were fetched from upstream at the declared commit and hash-match byte for byte, so the periphery the token trusts is exactly what it claims to be. No submodule is present.
• A scratch test deployed the token by CREATE2 from a factory contract, moved ten percent to a distributor, seeded a manager contract, and bought and sold back through transfer and transferFrom. Every balance was exact and total supply never changed. The runtime bytecode contains no DELEGATECALL, CALLCODE or SELFDESTRUCT.
• The existing 30-test suite, including the two stateful invariants, passes.

Static analysis leads

• Slither reported nothing. The aderyn large-numeric-literal note is a compile-time constant equal to the stated supply and is style only.

Trust assumptions, not defects

• Whoever calls the constructor holds the entire supply. Under the launch flow that is the factory, which is the intended design.
• The standard ERC-20 allowance replacement race exists and is documented in the README.

Nothing in the assigned area was left unreached.

The review is complete and the working tree holds only the findings file plus ignored build output.

Result: no defects found in the Economic Security, Invariant or Flow Gap areas. The findings file at .imd-findings.json has an empty findings list and a seven-row coverage record.

What I checked and how:

• Code under review. The token is fifteen lines: it inherits the vendored OpenZeppelin v5.1.0 ERC-20 and mints one billion tokens with 18 decimals to the constructor caller. The vendored files match the hashes recorded in DEPENDENCIES.json and read as canonical upstream content. The compiled ABI exposes only approve, transfer and transferFrom as state-changing functions, and the storage layout is the five standard slots.
• Economic Security guide. No external dependencies, oracles, callbacks or sentinel-address paths exist. Transfers deliver exact amounts with no fee, rebase, pause or blacklist. ERC-20 compliance holds, with reverts rather than false returns.
• Invariant guide. Total supply equals the manifest string and the sum of balances in every path. No mint or burn is reachable after construction. Allowances decrement exactly and roll back on failure. The existing 128-run stateful invariant suite and 30 unit tests pass.
• Flow Gap guide. I ran a scratch test modelling the launch: factory receives the whole supply under CREATE2, forwards the swarm share, settles the pool share by balance delta as Uniswap v4 does, forwards the remainder, and a trader buys and sells. Every flow arrived whole and the supply was conserved. The scratch directory was removed afterwards.
• Static analysis lead. The large-numeric-literal note is informational. The literal evaluates to exactly 10^27, which matches the manifest and README.

One row is marked unreached. A real Uniswap v4 PoolManager seed and swap could not be run because v4-core is not vendored and the protected harness needs launch environment parameters. For a plain ERC-20 with exact transfers, the modelled settlement is equivalent, so I expect that check to pass when the harness runs.

Trust assumptions to note for the author. The whole supply sits with the deployer after construction, which is the factory in this launch design. The standard ERC-20 approve replacement race exists and is documented in the README. Neither is a defect.

Extended the existing tests with failure paths, allowance boundaries, rollback checks, and random-sequence invariants.

forge build and forge test pass: 40 tests, 1,000 runs per fuzz test, and 16,384 invariant handler calls.

Only the two test files changed. No defects found.

The review is complete and the findings file is written and validated. The working tree is unchanged apart from the required .imd-findings.json.

Result: no permission, trust-gap or asymmetry defect in the ADAM token. The contract is the vendored OpenZeppelin v5.1.0 ERC-20 plus a constructor that mints exactly 10^27 units to the deployer. There is no owner, role, initializer, pause, blacklist, mint path, fee, hook or external call. The compiled ABI exposes only approve, transfer and transferFrom as state-changing functions, and the runtime bytecode contains no DELEGATECALL, CALLCODE, SELFDESTRUCT, CALL or STATICCALL.

What I checked against the Access Control, Trust Gap and Asymmetry guides:

• Access surface. Every writer of balances, allowances and supply is one of the three ERC-20 paths, authorized by msg.sender alone. The deployer or factory cannot move a holder's balance without an allowance.
• Supply after deployment. The mint branch is reachable only from the constructor. The 128-run stateful invariant and the admin-selector probes confirm supply stays fixed.
• Paired-function symmetry. transfer and transferFrom share the same debit and credit path. transferFrom only adds the allowance check, with the sticky max allowance behaving as OpenZeppelin documents.
• Launch flows. Transfers deliver exact amounts, so the factory, distributor and PoolManager need no exemptions and the swarm share arrives whole.
• Dependency trust. All six OpenZeppelin files are byte-identical to the pinned upstream commit.

One info-level finding was recorded: DEPENDENCIES.json records hashes for seven forge-std files that do not match the committed copies. The files were reflowed by forge fmt after vendoring. Stripping whitespace makes them identical to upstream, so no code changed, but the provenance record the README offers does not verify. The fix is to re-record the hashes or re-vendor the unformatted files.

Coverage has eight rows: the three listed entry points and the constructor all hold, three invariants hold, and the forge-std provenance row points at the finding. No high or critical finding exists, so no proof test was written.

One deployment note outside my area: the runtime uses PUSH0 and MCOPY, so the target chain must support the Cancun EVM. The chain is not named in this repository, so I did not record it as a finding.

Review complete. The findings file is written and validated. No source files were changed; the only new file is the required .imd-findings.json, which git does not show because the working tree status is clean apart from it being untracked-and-ignored or not yet listed.

Outcome: the ADAM token is clean. It is an unmodified OpenZeppelin v5.1.0 ERC-20 whose argument-free constructor mints exactly the manifest's supply to msg.sender. I kept one specialist finding, at info severity, and found nothing new.

What I reproduced

• The one specialist finding holds. Seven forge-std files under lib/ hash differently from the values recorded in DEPENDENCIES.json. I re-fetched each of the seven from the pinned upstream commit: upstream hashes match the record, and stripping whitespace from upstream and committed copies gives identical bytes. It is a formatting-only reflow with no code change. The six OpenZeppelin files, the only production dependency, verify byte-for-byte. Severity stays info since only the README's offline provenance claim is affected.
• The other three specialists and the independent tester reported nothing, so there were no duplicates to merge.

My own pass over the code

• All three entry points behave as standard OpenZeppelin ERC-20: zero-address and insufficient-balance reverts, exact amounts moved, infinite allowance preserved, finite allowance decremented with rollback on revert.
• The compiled ABI exposes no owner, mint, burn, pause, blacklist, or upgrade surface. Decimals return 18.
• I scanned the runtime and creation bytecode myself: no DELEGATECALL, CALLCODE, SELFDESTRUCT, CALL, STATICCALL or CREATE opcodes.
• The manifest is consistent with the code, including the supply constant and the provenance sqrtPriceX96 for ETH as currency0. Economics cannot be checked against the job from this tree.
• Build, format check, and the full suite of 40 tests plus 2 invariants pass offline. The aderyn large-literal lead is the intended supply constant and is not a defect.

Coverage record: all three entry points marked holds, plus four invariant rows. No proof test was needed since nothing reached high or critical.
