Implemented IDM with 18 decimals and exactly 1,000,000,000 tokens minted once to the deployer. No admin powers or further minting.

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

Passed forge build, seeded forge test (36 tests), and forge fmt --check using Solidity 0.8.26.

I found no defects in src/IDMToken.sol. The findings list in .imd-findings.json is empty, and every entry point has a coverage row.

What I checked (Execution Trace, Periphery and First Principles):

• The contract itself: IDMToken is a plain OpenZeppelin v5.0.2 ERC20 that mints 1,000,000,000 × 10¹⁸ once, to msg.sender, in the constructor. It changes nothing in the library and adds no owner, mint, pause, fee, hook or external call.
• The library code: the vendored ERC20.sol, IERC20.sol, IERC20Metadata.sol, Context.sol and draft-IERC6093.sol files match the sha256 hashes in DEPENDENCIES.json, so the library has not been altered.
• Transfers: I traced transfer and transferFrom through _update and _spendAllowance. Zero addresses revert, a short balance or allowance reverts, the exact amount moves, and an unlimited allowance is not reduced. With no fee or burn, the launch's own transfers move exactly what they say: factory to distributor, distributor to claimants, the pool seed, and swaps.
• Approvals: approve rejects zero addresses, sets the allowance exactly and emits the event.
• Supply: nothing can mint or burn after deployment, and there is no DELEGATECALL, CALLCODE or SELFDESTRUCT. Decimals are 18, name and symbol are "IDM", and the contract name IDMToken fits the manifest's 32-character limit.
• Static analysis lead: aderyn flagged the large number at line 12. It is 1_000_000_000 * 10 ** 18, which is correct and readable, so it is not a defect.
• Tests: forge test passed all 36 tests, including the invariant suite. I did not run the protected launch tests, because they need the factory environment variables and the floor harness.

Coverage rows: approve, transfer and transferFrom are all holds, plus two invariant rows (fixed supply, and decimals/name/symbol), also holds. No files in the repository were changed.

I found no math problems in the IDM token, so .imd-findings.json has an empty findings list. It also has a coverage row marked holds for each of the three entry points, plus three for the supply rules I checked.

What the code is: src/IDMToken.sol is OpenZeppelin's standard ERC20 (v5.0.2) with one constant, INITIAL_SUPPLY = 1_000_000_000 * 10 ** 18. The constructor mints that once to the deployer. There is no fee, burn, owner or later minting, and the only arithmetic is OpenZeppelin's balance and allowance bookkeeping. The vendored ERC20 and Context files match the hashes pinned in DEPENDENCIES.json.

Checked against the three guides:

• Math Precision: the constant is exactly 10^27, which fits easily in a uint256, and is computed at compile time. There are no divisions, decimal conversions, narrowing casts or shifts anywhere. The subtractions that skip overflow checks are each guarded by a comparison first.
• Boundary: I traced these edge cases:
  • Transfers of 0 succeed.
  • Transferring an account's full balance succeeds, and one unit more reverts.
  • Sending to or approving the zero address reverts.
  • An allowance equal to the amount drops to 0, and one unit short reverts.
  • An allowance of the maximum value is never reduced, which is OpenZeppelin's documented behaviour.
• Numerical Gap: with no rounding anywhere, nothing can drift. The supply only changes in the constructor, so the total always equals the sum of balances. Launch flows (seeding the pool, the distributor, swaps) move exactly the amounts they say.

Static-analysis lead: aderyn flagged src/IDMToken.sol:12 as a "large numeric literal". The value is correct; it's a style note, not a defect.

Tests: forge test passes all 36 existing tests, including the invariant suite (256 runs, 16,384 calls, no reverts). I didn't run the protected launch tests: they need the factory harness and Uniswap v4 code, which aren't in this tree. I wrote no proof tests because there was nothing to reproduce. Every guide item that applies to this code is covered.

Created launch.json matching IDMToken, its exact supply, empty constructor arguments, and the required pool and economics.

Validation passed: manifest and constructor ABI checks, forge build, and all 36 tests with the supplied fuzz seed. Only launch.json is changed for submission.

The review is complete and .imd-findings.json is written with one informational finding and eleven coverage rows. No repository files were changed.

Outcome. The permission model of src/IDMToken.sol holds across all three assigned guides. The contract is an unmodified OpenZeppelin v5.0.2 ERC-20 with a constructor that mints the full supply once to msg.sender and nothing else. There are no roles, owner, initializer, pause, blacklist, fee, exempt list or admin variant of any user function, so there is no guard gap, no escalation path, no asymmetric writer and no privileged actor whose action could redirect value between holder classes.

What I verified.

• All three ABI entry points plus the constructor, traced through the vendored library, which matches its upstream checksum.
• Supply cannot grow after launch, the runtime has no DELEGATECALL, CALLCODE or SELFDESTRUCT, and launch flows move exactly the stated amount.
• The existing 36-test suite passes with the README's seed, and forge fmt --check passes.
• The aderyn large-literal lead is a compile-time constant equal to 1e27 and not a defect.

One informational finding, outside my area. DEPENDENCIES.json records SHA-256 values that 19 vendored forge-std files no longer satisfy, and the README states all checksums matched. I fetched the pinned archive, whose hash equals the recorded one, and confirmed every difference is forge fmt line re-wrapping with no token-level change. forge-std is test-only and does not reach the deployed bytecode, so this is a provenance inaccuracy rather than a security issue. The fix is to restore the upstream bytes or regenerate the recorded hashes and correct the README sentence.

Not reported as defects. The ERC-20 approve replacement race and the fact that whoever deploys receives the whole supply are both inherent to the requested standard token and the launch design. They are documented as trust assumptions in the coverage record.

The review is complete. The findings file is written and validated, and no tracked file was changed.

Result: no economic, invariant or flow-gap defect in IDMToken. The contract is an unmodified OpenZeppelin v5.0.2 ERC-20 with a single constructor mint of 1e27 units to the deployer and no owner, mint, burn, pause, fee or callback path. I verified the vendored OpenZeppelin sources byte for byte against the upstream commit, so the inherited transfer logic is exactly what it claims to be.

What I checked, in the assigned order:

• Economic Security: no external dependencies, no price-dependent operations, no sentinel-address paths beyond ERC-6093 reverts, no fee-on-transfer or exemption list that could short a launch flow. Nothing to extract.
• Invariant: the sum of balances equals total supply equals the constant forever, since _update is the sole writer and _mint is reachable only from the constructor. Allowance coupling and rollback hold. The project's seeded suite passed, with 36 tests and 16,384 invariant calls.
• Flow Gap: the factory to distributor to claimant flow, the pool seed, and a buy and sell through the PoolManager all move exact amounts with no callbacks. The manifest's only valid values are empty constructor arguments and the 1e27 supply, which the README documents.

Build, tests and forge fmt --check all pass.

One info-level note was recorded. The provenance record in DEPENDENCIES.json lists genuine forge-std v1.9.7 hashes, but 19 vendored forge-std files were reformatted to the project's line width and no longer match them. The diff is whitespace only, forge-std is test-only, and the README sentence claiming all checksums matched is therefore inaccurate. The reproduction is a single sha256sum on lib/forge-std/src/Vm.sol.

Coverage: all three listed entry points and five invariant or flow rows are answered, eight rows total. No high or critical findings, so no proof test was written.

Added 15 edge-case and fuzz tests covering allowance limits, revocation, failed-call rollback, and exact transfers. Expanded stateful invariants to 10 randomized actions plus holder balance recovery.

forge build and forge test pass with the required seed: 51 tests, 9,216 fuzz cases, and 32,768 invariant calls.

Only test/ changed. No implementation defects found.

The review is complete. The findings file is written and validated, and no repository file was changed.

Outcome: the IDM token has no defect that affects funds, supply or the launch flows. The two specialists who reported something both found the same provenance issue, which I reproduced and merged into one info finding. I added one more info finding of my own.

What I verified

• The token is an unmodified OpenZeppelin v5.0.2 ERC-20 with a parameterless constructor minting the full supply to msg.sender once. All six vendored OpenZeppelin files are byte-identical to the pinned upstream archive, which I re-fetched and hash-checked.
• All three entry points hold: approve, transfer and transferFrom are the untouched library implementations, with no fee, burn, hook, owner or bypass. The compiled runtime contains no DELEGATECALL, CALLCODE or SELFDESTRUCT, and the ABI exposes no mint, pause or blacklist call.
• The manifest is consistent with the code: contract name, metadata, empty constructor arguments and a supply equal to the constructor's mint.
• The project's 51 tests, including fuzz and invariant suites, pass with the README's seed. Formatting check passes.

Findings reported, both info severity

1. Nineteen forge-std files do not match the hashes in DEPENDENCIES.json, so the README's "all checksums matched" claim is false. The recorded hashes are the genuine upstream values, and the differences are whitespace-only reformatting of test-only code. The specialists' duplicates were merged into this one.
2. The README states the repository deliberately provides no launch.json, but the manifest step added one. Documentation only.

Dropped: the aderyn large-numeric-literal line, which is cosmetic. The protected launch test could not be run locally because it depends on v4-core sources not in this tree. No critical or high finding exists, so no proof test was needed.
