I found no economic defects, so I wrote .imd-findings.json with an empty findings list and a coverage row for each of the three entry points, all marked holds.

What the code is: src/YOLO.sol is the unchanged OpenZeppelin v5.1.0 ERC20 with nothing overridden. Its constructor mints INITIAL_SUPPLY = 1_000_000_000 * 10 ** 18 (10^27) to msg.sender, which is the factory, once. It has no mint, burn, owner, pause, fee or upgrade function and no constructor arguments. The OpenZeppelin files match their recorded checksums.

Economic Security, Invariant and Flow Gap passes:

• Supply: the only mint is in the constructor and nothing can call one later, so the supply can't grow. It stays exactly what the manifest states and lands at the factory.
• Launch flows: no code runs on transfer. The swarm's 10% to the distributor, each claim, the pool seed, the remainder and trades through the PoolManager each move exactly the amount stated. Nothing depends on distributorOf.
• Allowances: transferFrom takes exactly the amount from the allowance (an unlimited allowance stays unlimited), then makes the same exact move. Nothing can move or freeze a holder's balance without their approval.
• Value extraction: with no fees, burns or price inputs, there is nothing to sandwich or round against.
• Checks run: the project's 29 tests pass, including the invariant suite of 256 runs and 16,384 calls. I could not run the protected floor test, because it needs the deployer's environment variables and floor files that aren't on this machine.
• Static analysis: the aderyn lead (large numeric literal at src/YOLO.sol:12) is style only; the value is correct at 10^27.

Outside my area (not reported as a finding): 7 vendored forge-std files don't match DEPENDENCIES.sha256, though DEPENDENCIES.md says they're unmodified. They're used only by tests and don't affect the deployed bytecode, but the integrity claim in DEPENDENCIES.md is wrong.

A clean review doesn't prove the code has no defects.

launch.json is written and verified. It is the only new file in the tree.

What the manifest says

• Kind custom_token, token contract YOLO, name and symbol YOLO, 18 decimals.
• Constructor arguments are an empty list. The compiled ABI confirms the constructor takes no parameters.
• Total supply is the constructor's single mint to msg.sender, 10^27 minor units, matching the INITIAL_SUPPLY constant.
• No application contracts, since the accepted tree contains only the token.
• Pool and economics objects are copied exactly as the launch defines them: IMD pair, fee 12500, tick spacing 60, the one-to-one provenance price, and the requester's 60% pool / 2,300 IMD cap / remainder address.
• Notes describe the token's fixed supply, full-value transfers, and absence of any privileged functions, at 962 characters.

Checks run

• forge build compiled cleanly with solc 0.8.26.
• forge test with the verifier's fuzz seed passed all 29 tests across 3 suites, including the two stateful invariants.
• A script confirmed the manifest has only the six schema keys, the supply string equals 1,000,000,000 times 10^18, and pool and economics match the job verbatim.
• git status shows only the untracked launch.json. No other file was touched.

The protected tests run in the verifier's own harness with resolved launch environment variables, so they were read rather than executed here. The token's plain OpenZeppelin ERC-20 behavior satisfies each of their requirements: whole supply to the factory, untaxed transfers, no supply growth, no privileged calls, and no DELEGATECALL, CALLCODE or SELFDESTRUCT.

The review is complete. .imd-findings.json holds one low finding and eight coverage rows; the working tree is otherwise untouched.

Math area verdict: clean. YOLO is OpenZeppelin v5.1.0 ERC20 plus one constructor mint, and the vendored ERC20 closure matches upstream byte for byte. There is no division, scaling, downcast, fee or external call anywhere in the token, so the Math Precision, Boundary and Numerical Gap failure modes have nothing to attach to. I confirmed the edges directly with a scratch Foundry test, since removed:

• Supply constant is exactly 1e27 and equals one billion times ten to the decimals() power.
• Transfers at balance, balance plus one, zero and max uint behave as documented, from both full and empty accounts.
• Allowance at max is infinite, at max minus one is finite and decrements, and a failed transfer rolls the allowance back.
• Every basis-point split of 1e27 is exact, so the swarm's 10% and any pool share leave no dust.
• Sum of balances equals total supply under fuzzing, and the project's own 256 by 64 stateful invariant run passes.
• No payable, receive or fallback path exists; ETH sent with any calldata reverts.

The aderyn "large numeric literal" lead is cosmetic: the constant is compile-time checked and correct.

One finding, outside my area, low severity. The README documents sha256sum --check DEPENDENCIES.sha256 as a build step and DEPENDENCIES.md claims forge-std is unmodified upstream. Both are false on the submitted tree: seven forge-std files were re-wrapped by a formatter after the hash file was written, so the check reports seven failures and exits nonzero. The recorded hashes are the genuine v1.9.7 ones. The files are test-only and the token bytecode is unaffected, but the deliverable's provenance claim does not hold. The fix is to restore the files from the v1.9.7 archive or regenerate the hashes and amend the note.

All three ABI entry points are marked holds, with extra rows for the constructor, the conservation invariant, launch split arithmetic, boundary classes and metadata. Nothing in my area was left unreached.

The review is complete and the findings file is written and validated. The working tree is otherwise unchanged.

Outcome. The YOLO token's permission model is clean. It is OpenZeppelin v5.1.0 ERC-20, byte-identical to upstream, plus a constructor that mints 1e27 units once to the deployer. There are no roles, owner, initializer, proxy, hooks, fee exemptions or callbacks, so none of the Access Control, Trust Gap or Asymmetry failure modes have a surface to attach to.

What I checked in my area

• Access Control: every storage writer is one of approve, transfer or transferFrom, each guarded only by msg.sender or allowance, with no second writer to any slot. Fourteen admin-style selectors called from the deployer and from a stranger all revert with empty returndata. Reachable runtime code contains no DELEGATECALL, CALLCODE or SELFDESTRUCT.
• Trust Gap: no privileged actor exists, so no access-times-economics seam is possible. The factory holds the whole supply after construction and has no power over holders beyond ordinary ERC-20 rules. The deployer's transferFrom without allowance reverts.
• Asymmetry: transfer and transferFrom with max allowance leave identical balances and supply. approve and transferFrom mirror each other correctly. The one inherent ERC-20 approve front-run is possible and is already documented in the README.

One finding, low severity, outside my area. The README's documented step sha256sum --check DEPENDENCIES.sha256 fails on the committed tree. Seven forge-std files were reformatted after their hashes were recorded. I confirmed the recorded hashes are upstream v1.9.7 and the committed files differ only by line reflows, so the test library is semantically intact and the token is unaffected. The deliverable's provenance claim is nonetheless false as shipped. The fix is to regenerate the hash file or restore the upstream bytes.

Coverage. All three listed entry points hold, plus rows for the constructor and four invariants. The full project suite passed under the README's fuzz seed. The protected launch harness could not run here because it depends on v4-core sources not in this tree, so I mirrored its opcode and privilege checks in a scratch test, which passed, and then removed it.

Review complete. The findings file is written and validated, and the working tree holds only .imd-findings.json beyond the original commit.

Outcome: the YOLO token itself is clean in my area. The one defect found is a low-severity provenance issue in the vendored test dependency.

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

• src/YOLO.sol is a 17-line contract: unmodified OpenZeppelin v5.1.0 ERC20 plus a constructor that mints 1e27 units to msg.sender. I traced approve, transfer and transferFrom through _approve, _spendAllowance, _transfer and _update for sentinel inputs, zero and max amounts, partial-update and stale-read paths. All failure paths revert atomically and there are no external calls, callbacks, hooks or admin surface.
• Periphery: I hashed the five vendored OpenZeppelin files against the upstream v5.1.0 tag. They match byte for byte, so the production dependency closure is genuinely unmodified.
• First principles: supply constant equals 1,000,000,000 × 10^18, decimals default to 18, name and symbol are YOLO, the whole supply lands on the immediate deployer under CREATE2, and launch flows (factory to distributor, claims, pool round trips via transfer and transferFrom) move exact amounts. A scratch Foundry probe confirmed these plus the rejection of 22 common mint, pause, freeze and seize selectors from both a stranger and the deployer, and an opcode scan of the runtime found no DELEGATECALL, CALLCODE, SELFDESTRUCT or CALL.
• The project's own 29 tests, fuzz and invariants pass with the README's seed, and forge fmt --check passes.

Finding (low): the README and DEPENDENCIES.md tell the operator to run sha256sum --check DEPENDENCIES.sha256, and that command fails with seven mismatches in lib/forge-std/src. The recorded hashes are the real upstream v1.9.7 hashes. The vendored copies were reformatted after the hash file was written. Content is identical once whitespace is removed, so behaviour is unaffected, but the documented integrity step is red and the "unmodified upstream" claim is false for forge-std. Fix by restoring the seven files from the v1.9.7 archive or regenerating the hash file and amending the note.

Coverage: all three listed entry points plus the constructor and four invariant or periphery rows are recorded as holds, with the forge-std row pointing at finding 1. Nothing in my area was left unreached. The protected launch test's pool seed and swap paths need the network harness and v4-core sources that are not in this tree, so I could not execute them here. The token has no fee or hook logic that could affect them.

Added failure-path and fuzz tests covering allowance lifecycles, authorization, rollback, and transfer properties. Expanded invariants to 11 actions across four actors.

Offline build and tests passed with the required seed: 48 tests passed, including 32,768 invariant calls.

Only test/ changed. No implementation defects were found.

The review is complete and written to .imd-findings.json. No tracked file was changed.

Outcome: the token is clean. The YOLO contract in src/YOLO.sol is an unmodified OpenZeppelin v5.1.0 ERC20 with a no-argument constructor that mints exactly one billion tokens with 18 decimals to the deployer. I confirmed the five OpenZeppelin files match the upstream tag byte for byte, the build succeeds, all 48 project tests pass, and the bytecode is far under the size limits with no delegatecall or selfdestruct. The manifest's constructor arguments, supply and decimals agree with the code.

Findings kept: one, at low. Three specialists reported the same root cause and I merged them.

• Documented hash check fails. Running the sha256sum --check step the README names reports seven forge-std files as mismatched. The recorded hashes are the genuine upstream v1.9.7 hashes. The vendored copies differ only by whitespace, which I verified by stripping whitespace from both sides and comparing. These files are test-only and the token is unaffected, so the defect is a false provenance claim, not a security issue. The fix is to restore the seven files or regenerate the hash file and amend the dependency note.

Dropped or absent: the test writer and the economics specialist reported nothing, and the static-analysis lead about the large numeric literal checked out as correct.

Coverage: all three entry points hold, plus three invariant rows for the supply, deployability under the launch floor, and the static-analysis lead. No proofs were attached since nothing reached high or critical.
