Implemented NumosIMD.sol: NUMOS, 18 decimals, exactly 1,000,000,000 tokens minted once to the constructor caller.

Dependencies are vendored. README.md documents assumptions, deployment parameters, and operational responsibilities.

Verified with Solidity 0.8.26:

• forge build — passed
• forge test — 29 passed, including failure, fuzz, and invariant tests
• forge fmt --check — passed
• Clean offline build and parallel tests with an empty environment — passed

The protected Uniswap launch integration remains for the external verifier.

The findings file parses as valid JSON with zero findings and six coverage rows. Git status shows only the required output file, so nothing stray is left.

Result: no defects found in the control-flow area. The findings file at .imd-findings.json holds an empty findings list and a full coverage record.

What I checked, against the Execution Trace, Periphery and First Principles guides:

• Entry points. All three listed functions are the unmodified OpenZeppelin ERC20 paths. Transfer debits the sender before crediting the receiver, so self-transfers net to zero and no partial state survives a revert. Allowance spending reads once, reverts on shortfall, and treats max uint256 as infinite. There are no fees, callbacks, sentinels or external calls to diverge.
• Constructor. The supply constant evaluates at compile time to 10^27 and is minted once to the immediate caller, so a CREATE2 deploy from the factory credits the factory. No mint, burn, owner, pause or upgrade path exists after construction.
• Periphery. I downloaded the six vendored OpenZeppelin files at the pinned v5.0.2 commit and diffed them against lib/. They are byte-identical.
• Build and tests. The project compiles under solc 0.8.26 and formatting passes. All 29 existing tests pass, including the 512-run fuzz cases, the 128 by 64 stateful invariant and the opcode scan for DELEGATECALL, CALLCODE and SELFDESTRUCT.

The two static-analysis leads were benign. Slither reported nothing, and the aderyn large-literal note points at a compile-time constant.

One open item for the launch operator, not a code defect: the build targets Cancun, so the target chain must support PUSH0. The README already states this.

Created launch.json with exact supply, empty constructor arguments, verbatim economics, and the required paired currency.

Validation passed: supplied schema and refinements, constructor ABI, offline build, formatting check, and all 29 tests across two fuzz seeds.

Only launch.json is a deliverable change. Protected seed/swap integration requires infrastructure absent from this tree.

Review complete. No defects found in the economics, invariant or flow-gap areas.

Result: .imd-findings.json holds an empty findings list and nine coverage rows, all holds, covering the three listed entry points plus the invariants checked. The scratch test was removed, so the findings file is the only addition to the tree.

What was verified

• The token is a stock OpenZeppelin v5.0.2 ERC-20 with a single constructor mint of 10^27 units to the caller. All five vendored library files hash-match the upstream commit byte for byte, so there is no hidden transfer override.
• The compiled ABI exposes only approve, transfer, transferFrom and views. Twenty admin-style selectors (mint, burn, pause, blacklist, seize, upgrade, permit, rescue and others) all revert when called from the factory, and the deployer cannot pull a holder's balance without allowance.
• Launch flows move exact amounts: swarm share to the distributor, claims out of it, the pool share, the remainder, and the approve-plus-transferFrom pattern the PoolManager uses. Supply conservation held across the project's invariant suite and a scratch fuzz run.
• No external calls, callbacks, exemptions or fee branches exist, so no flow-gap seam between execution and periphery can arise. The aderyn large-literal lead is benign: the literal equals the manifest supply exactly.

Trust assumptions, not defects: whoever deploys the token (the factory in this launch) receives the full supply and is responsible for its distribution. There is no recovery path for tokens sent to unusable addresses, which the README already states.

The review is complete. No defects were found in the Math Precision, Boundary, or Numerical Gap areas, and .imd-findings.json holds an empty findings list with seven coverage rows (all three entry points plus four invariants, all holds).

What was checked

• The contract itself. NumosIMD is a 16-line wrapper around OpenZeppelin ERC20. Its only arithmetic is the compile-time constant for supply, which evaluates to exactly 10^27 and fits in 90 bits. The aderyn "large numeric literal" lead is style only.
• The vendored dependency. The SHA-256 of the vendored ERC20.sol matches the upstream v5.0.2 file byte for byte, so the arithmetic paths are the audited ones. Every unchecked block in _update and _spendAllowance sits behind an explicit revert guard, and the balance-add is bounded by a total supply that can never grow after construction.
• Boundary enumeration. The token has no payable function, no receive or fallback, no external calls, no bytes decoding, no downcasts, and no division. The only sentinel branches are OpenZeppelin's zero-address rejections. Value and unknown-selector calls revert.
• Empirical edges. A scratch suite of 14 tests passed, covering 1 wei transfers, full-supply and supply-plus-one, max-uint amount, self-transfer at full balance via both transfer and transferFrom, exact-allowance and allowance-plus-one, the max-uint infinite-allowance sentinel versus max-minus-one, zero-amount transferFrom with zero allowance, the token contract as recipient, an 8-holder fuzzed balance-sum conservation check, and a fuzzed 10% swarm / poolBps / remainder launch split landing exact. The existing 29 project tests, including the 128x64 stateful invariant, also pass.

Outside my area nothing severe surfaced either: supply mints once to msg.sender (the factory), decimals match the manifest, no mint, burn, pause, blacklist, delegatecall, or selfdestruct exists in the ABI or runtime.

Not reached: the real Uniswap v4 seed and swap integration in the protected test needs launch infrastructure and environment inputs not present here, so that path was reasoned about from the token's transfer semantics rather than executed.

The scratch test directory was removed. The working tree is unchanged apart from the findings file.

The findings file is in place and excluded from git by the harness, the scratch directory is gone, and the tracked tree is unchanged. The review is complete.

Outcome: no defects in the assigned area. NumosIMD is a bare OpenZeppelin v5.0.2 ERC20 with one constructor mint. It has no owner, role, modifier, initializer, fallback, receive, hook, or external call, so there is no permission model to bypass. One info-level provenance note is recorded in .imd-findings.json.

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

• Permission map. The compiled ABI exposes exactly three state-changing functions. Storage is the five OpenZeppelin slots. The runtime bytecode contains no CALL, DELEGATECALL, CALLCODE, STATICCALL, CREATE, CREATE2 or SELFDESTRUCT opcodes.
• Confused deputy and library trust. All six vendored OpenZeppelin files hash-match upstream commit dbb6104 byte for byte. Context returns plain msg.sender, so no forwarder path exists.
• Deployer power. Supply is minted to msg.sender, which is the CREATE2 factory, not tx.origin or the requester. The factory cannot pull a holder's balance without allowance. Strangers cannot spend or set others' allowances.
• Asymmetry. transfer and transferFrom move identical amounts with identical supply and event effects. Infinite allowance is never decremented, finite allowance is. Zero-value transferFrom without allowance moves nothing.
• Launch flows. Factory to distributor to claimant, and factory to pool to trader and back, all arrive whole. No tax, burn, or exemption logic exists.
• Static-analysis lead. The aderyn large-literal note is a compile-time constant equal to 10^27 and is not a defect.

The one recorded item (info). Six of the 26 vendored forge-std files differ from the pinned commit 3b20d60 by whitespace only, so the README's claim that lib/dependencies.json records the exact source is not byte-accurate. This is test tooling only and has no effect on the deployed token.

Coverage. All three entry points are marked holds, plus rows for the constructor and three invariants. The existing 29 tests and my 8 scratch probes all passed. Trust assumptions to carry forward, not defects: the launch factory holds the entire supply after deployment, and the standard ERC20 approve-overwrite race applies, which the README already documents.

Added 16 boundary, failure-path, and fuzz tests; expanded invariants to 32,768 randomized calls checking supply, balances, allowances, and rollback.

forge build and forge test pass offline: 45 passed, 0 failed.

Only test/ changed. No implementation defects found.

The review is complete. The findings file is valid JSON, the cited snippet matches line 13 of the dependencies record, and no tracked file changed.

Outcome: the token is clean. NumosIMD is the unmodified OpenZeppelin v5.0.2 ERC-20 with a parameterless constructor that mints the manifest supply of 10^27 minor units once to the factory. It has no owner, mint, burn, pause, blacklist or upgrade surface. All three entry points in the ABI behave as the library specifies, and the launch flows the protected test exercises move exactly what they say.

Specialist findings settled

• The one finding from the permissions area reproduces. I fetched all 26 forge-std files from the pinned commit and 6 differ only in whitespace, while the 6 OpenZeppelin files are byte-identical to their pinned commit. Kept at info severity since it affects only test-harness provenance, never the deployed token.
• The other three areas and the independent tester reported nothing, so there were no duplicates to merge.

My own pass found nothing further. I checked constructor arguments against the manifest, recomputed the manifest's sqrt price from the stated economics and supply and it matches, confirmed decimals and supply agree with the manifest, confirmed there are no git submodules, and ran the full project suite with all 45 tests passing. The static-analysis lines were a clean slither run and one aderyn style note on the supply literal, which is not a defect.

Coverage answers all three entry points as holds, plus three invariant rows covering supply minting, absence of privileged powers, and manifest consistency.
