Implemented IMD RISK (RISK): 1,000,000,000 tokens with 18 decimals, minted once to the deployer. Includes vendored dependencies, deployment documentation, and 34 tests.

Passed forge build, seeded forge test, and forge fmt --check. Offline rebuild and tests also passed with an empty environment.

Full factory/Uniswap integration remains for the external protected verifier.

I found no defects in the math of src/RiskToken.sol, so .imd-findings.json holds an empty findings list and a coverage row for each entry point. The existing test suite passes: 34 tests, none failing.

There is very little math to check. The contract is a plain OpenZeppelin ERC20 that sets the name to "IMD RISK" and the symbol to "RISK", uses 18 decimals, and mints a fixed constant of 1_000_000_000 * 10**18 once to the deployer. It has no fees, burns, taxes, rounding or casts of its own, and no other functions.

Entry point	Verdict	Why
approve(address,uint256)	holds	No arithmetic. A zero-address spender reverts, and a maximum allowance is treated as unlimited by design.
transfer(address,uint256)	holds	The balance is checked before the subtraction. The receiver's addition can't overflow because all balances add up to the fixed 1e27 supply. Transfers of 0 and of a full balance move exactly that amount.
transferFrom(address,address,uint256)	holds	The allowance is checked before it is reduced. Nothing is taken off a transfer, so the launch transfers (factory to distributor, the pool seed, swaps) arrive whole.
Supply invariant	holds	The supply is a compile-time constant, minted only in the constructor, and no function can mint or burn afterwards.

Both tool leads were empty: Slither had no results, and Aderyn's "large numeric literal" flag at line 10 is a style note with no numerical effect.

All three of my guides (Math Precision, Boundary and Numerical Gap) were covered for every entry point; nothing was left unreached.

I found no defects in RiskToken, so .imd-findings.json has an empty findings list. It also has a holds coverage row for each of the three entry points, plus one for the fixed-supply rule.

What the code is: src/RiskToken.sol is a 17-line OpenZeppelin v5.4.0 ERC20. It has no overrides, and its constructor mints 1,000,000,000 × 10^18 to msg.sender once, with name "IMD RISK", symbol "RISK" and 18 decimals. The ERC20.sol, Context.sol and IERC20.sol files in lib/ match the pinned hashes, so the inherited code is the standard library, unmodified.

Execution Trace guide:

• transfer: the zero-address checks hold, an amount above the balance reverts, and the unchecked arithmetic is bounded by the balance check and the total supply.
• transferFrom: the allowance is spent before the transfer, so a revert undoes both. A finite allowance is reduced exactly; the maximum allowance is never reduced, which is intended. A zero amount needs no allowance and moves nothing.
• Settling transfers to self or of zero: both leave balances unchanged.
• approve: changing a nonzero allowance has the usual ERC-20 approve race. That's part of the standard, so I didn't report it.

Periphery guide: the only inherited code is the pinned OpenZeppelin ERC20 and its Context, interface and errors.

First Principles guide: the total supply can't change after the constructor. There are no mint or burn functions, no owner, no pause, no fee or burn on transfer, and no DELEGATECALL, CALLCODE or SELFDESTRUCT. Launch transfers to the distributor and the pool manager therefore arrive whole.

Static analysis: aderyn's one low lead, the large number at line 10, is the supply constant written as 1_000_000_000 * 10 ** 18, which is correct. Slither reported nothing.

Checks: the project's 34 existing tests pass, including the invariant run. I also ran a 7-test scratch file covering transfers to self, over-balance and zero-address reverts, infinite and finite allowances, zero-amount transferFrom and the token's name, symbol and decimals. All passed, and I deleted the file afterwards.

Not covered: I didn't run the two protected floor tests, because the harness and Uniswap v4 files they import aren't in this tree. No pass was cut short; the whole area was covered.

The working tree is unchanged apart from .imd-findings.json, which git ignores.

Created launch.json matching RiskToken, its constructor supply, and the exact pool and economics values. No other submitted files changed.

Validation passed: manifest and constructor ABI checks, forge build, and all 34 tests using the supplied fuzz seed.

The review is complete. No defects were found in the assigned area, and the findings file records that with full coverage.

Outcome: .imd-findings.json holds an empty findings list and nine coverage rows. All three listed entry points are marked holds, with five additional invariant rows and one unreached row. No repository file was changed, and the scratch test directory was removed.

What was checked, against the Economic Security, Invariant and Flow Gap guides:

• The token is an unmodified OpenZeppelin v5.4.0 ERC-20 with one constructor mint. Every vendored library file hashes identically to the upstream commit and to the hashes recorded in the tree.
• The compiled ABI exposes exactly ten functions and no receive or fallback. Only approve, transfer and transferFrom change state, and none touches total supply.
• A scratch Foundry test reproduced the launch split of ten, eighty-eight and two percent, per-contributor claim shares, round trips at one wei and full balance, self-transfers, zero transfers, finite and infinite allowances, and rejection of ether. Every leg moved the exact amount and supply stayed at one billion tokens.
• A 512-run fuzz and the repository's own stateful invariant confirmed conservation of balances against supply.
• The supply fits the Uniswap v4 PoolManager's signed 128-bit deltas and 128-bit liquidity width.
• The repository's 34 tests pass under the pinned fuzz seed.

Not reached: the live pool seed and swap in the protected harness. The v4-core and floor contracts it imports are not in this tree, so that leg was reasoned from the token's exact-transfer semantics rather than executed.

Noted but not reported as defects: the standard ERC-20 approve-ordering race and the inability to recover tokens sent to the token contract itself. Both are inherent to plain ERC-20, are documented in the README, and have no attacker-profitable path here.

Review complete. The findings file is written and validated, and the working tree has no other changes.

Outcome. The token's permission model holds. RiskToken exposes only approve, transfer and transferFrom as state-changing entry points, all unguarded by design and all routed through unmodified OpenZeppelin code. There is no owner, role, initializer, pause, blacklist, mint, burn or upgrade path, and the runtime bytecode contains no CALL, DELEGATECALL, CALLCODE, CREATE or SELFDESTRUCT. The constructor mints exactly 10^27 units once to the immediate deployer, which in the launch is the factory, and _mint is unreachable afterwards.

One finding, low severity. The repository's own provenance record is false for the test library. lib/dependencies.json records SHA-256 digests that describe genuine upstream forge-std at the pinned commit, but seven of the thirty vendored forge-std files in the tree were reformatted after download and no longer match those digests or the "copied unchanged" claim. I confirmed the differences are line-wrapping only: every one of the seven is byte-identical to upstream once whitespace is stripped, so the test assertions are not tampered with and nothing in production is affected. The defect is that the documented verification method fails, which defeats its purpose. The production dependency is clean: all six OpenZeppelin files match both the recorded digests and upstream v5.4.0 byte for byte, and both release tags resolve to the pinned commits.

What I checked, by guide:

• Access Control: role map, inconsistent-guard search across every storage writer, initialization, escalation, confused deputy, delegatecall and proxy. Nothing reachable.
• Asymmetry: the approve/spend pair, transfer/transferFrom pair, mint/burn branches of _update, storage lifecycle. All mirror correctly, with the max-allowance sentinel honoured on both sides.
• Trust Gap: no privileged actor and no economic formula exist, so the seams reduce to deployment trust and dependency provenance, which produced the finding.
• Also run: the full delivered suite with the README's fuzz seed, format check, ABI and storage-layout inspection, opcode scan, and the launch floor's conditions from the protected test.

Not reported as defects. The ERC-20 approve race and zero-value transferFrom emitting events from any address are both standard-mandated, documented in the README and tested, so they appear only as notes in the coverage rows. The static-analysis lead about the large numeric literal is a style note; the constant evaluates to the correct supply.

Coverage record. All three listed entry points are marked holds with reasons, plus seven invariant rows, one of which points to the finding. No scratch test was needed since the only finding is low.

Added 16 tests and expanded stateful invariants to cover rejected calls, allowance changes, replayed spending, and integer boundaries.

Offline verification with the required seed passed:

• forge build
• All 50 tests
• 9,000 fuzz cases
• 32,768 invariant calls

Only test/ changed. No confirmed defects found.

The review is complete and the findings file is written. The working tree is clean apart from the findings file and the ignored scratch test.

Outcome: one low finding kept, no defects in the production contract.

• Kept, low: the specialist's forge-std provenance finding reproduces exactly. Seven vendored forge-std files differ from the digests in lib/dependencies.json and from the "copied unchanged" claim. I fetched each from the pinned upstream commit: the recorded digests describe upstream, and the vendored copies are whitespace-only reformats, so behaviour is unchanged and only the test library is affected. The six OpenZeppelin production files are byte-identical to upstream v5.4.0.
• Dropped: the aderyn large-numeric-literal lead. The constant is a readable expression equal to the manifest's supply.
• No specialist duplicates: three areas and the test writer reported nothing, so there was nothing to merge.

My own pass on RiskToken found nothing. It is an unmodified OpenZeppelin ERC20 with a no-argument constructor minting 10^27 units to the deployer. The compiled ABI exposes only the standard ERC-20 surface and INITIAL_SUPPLY. The runtime has no DELEGATECALL, CALLCODE or SELFDESTRUCT, and both creation and runtime sizes are far below the protocol limits. launch.json matches the contract on name, symbol, decimals, empty constructor arguments and total supply. The delivered suite passes, and my scratch test mirroring the protected harness flow passes as well.
