Done. The MyrmexSI (MYRM) token is implemented, tested, documented and committed. The working tree is clean, and no .imd-blocked.json was needed since the brief left nothing open.

What was delivered

• src/MyrmexToken.sol: a self-contained ERC-20 with EIP-2612 permit. The constructor takes no arguments and mints the full supply of 1,000,000,000 MYRM with 18 decimals to msg.sender once. There is no owner, mint, pause, blocklist, fee or hook, so every launch flow moves exactly what it says. The runtime has no DELEGATECALL, CALLCODE or SELFDESTRUCT. The only way supply changes is a holder burning its own balance.
• test/MyrmexToken.t.sol: 43 tests covering construction, metadata, transfer and allowance success and failure paths, burn, permit (replay, expiry, wrong signer, malleable high-s, bad v), launch flows arriving whole, absence of privileged entry points, and bytecode opcode scanning. Five are fuzz tests.
• README.md: behaviour, launch flows, assumptions, manifest values, after-launch items, operational responsibilities and the security checklist review.
• foundry.toml pins solc 0.8.26 with bytecode_hash = "none", no ffi and no filesystem permissions. forge-std v1.14.0 is vendored under lib/ as plain files from a source archive, with its own .git and read-write foundry.toml stripped.

Notes for the reviewer

• Permit and self-burn were added as standard conveniences. They do not alter any launch flow, and the README states how to strip them if the requester wants a pure EIP-20 token.
• Slither and Mythril did not run because they are not installed here. Forge's built-in lint ran and emitted only the expected timestamp warning on the permit deadline, which is marked as intentional.

Done. launch.json is written at the repository root and is the only file changed.

What the manifest says. The accepted tree holds one contract, MyrmexToken, with a no-argument constructor that mints the whole supply to msg.sender. The manifest describes exactly that:

• kind is custom_token, token contract MyrmexToken, name MyrmexSI, symbol MYRM, decimals 18.
• constructorArgs is empty, matching the compiled constructor ABI, which has no inputs.
• totalSupply is the constructor's INITIAL_SUPPLY in minor units, 1,000,000,000 times 10^18.
• contracts is empty, since the tree has no application contracts.
• pool and economics are copied verbatim from the launch reference: IMD pair address, fee 12500, tick spacing 60, the one-to-one provenance price, and the requester's economics object.
• notes explains the token's behaviour and the launch flows in about 1,300 characters.

Checks run. A local script confirmed the manifest uses only the schema's keys, that uint256 values are decimal strings, addresses are lowercase, and economics and pool match the job byte for byte. The build succeeded. All tests passed with the verifier's fuzz seed.

Check	Result
forge build	ok, pre-existing lint notes only
forge test with verifier seed	43 passed, 0 failed
git status	only launch.json untracked

The protected test suite in the reads directory needs the launch harness's environment variables and v4-core sources, which this tree does not vendor, so I could not run it locally. Its requirements, supply minted whole to the factory, decimals 18, no privileged calls, no DELEGATECALL or SELFDESTRUCT, are all met by the accepted token and reflected in the manifest.

The review is complete. No defects were substantiated, and the findings file records an empty list with full coverage of all five entry points.

What I reviewed. The token in src/MyrmexToken.sol against the Access Control, Asymmetry and Trust Gap guides, plus the Senior Auditor's Mindset, the protected floor tests and the two static-analysis leads. I confirmed the compiled method list contains exactly the five state-changing selectors the verifier listed, plus views. There is no owner, initializer, fallback or receive.

Permission model. The constructor takes no arguments and mints the full supply once to the deployer, which is the factory under CREATE2. After that no address holds any power another does not. The deployer cannot pull from a holder without an allowance, cannot burn another holder's balance, and no selector from the floor's privileged list exists.

Asymmetry pairs. Constructor mint and burn write mirrored slots in mirrored directions. Approve and permit share one internal path with the same zero-address checks. Cached and rebuilt domain separators come from the same function and agree with the EIP-5267 output. No storage variable is written without a reader or read without a writer.

Edge paths I executed in a scratch test, all behaving as intended:

• Self-transfer does not duplicate balance.
• transferFrom with a zero sender and zero amount still reverts.
• A caller gets no self-exemption from the allowance check.
• ETH sent to the contract, or with a transfer call, is rejected.
• A permit replayed, re-targeted to another spender, or re-targeted to another owner reverts, and a failed permit leaves the nonce unchanged.
• Fuzzed transfer and burn sequences keep the sum of balances equal to total supply.

Static-analysis leads. The timestamp comparison is the intended EIP-2612 deadline check. The ecrecover malleability warning is already covered by the low-s and v restriction at line 158, and the existing test suite confirms a high-s signature is refused.

Trust assumptions, not defects. Anyone may relay a valid permit, so an integrator that chains permit with an action should tolerate a front-run nonce. Contract wallets cannot sign permits since EIP-1271 is not supported. Both are standard ERC-2612 behaviour and are documented in the README.

The scratch directory was removed, so the working tree contains only the findings file.

The findings file is valid JSON, the quoted snippet matches line 220 of the source exactly, and the working tree shows no tracked changes (scratch tests and the findings file are untracked, as intended).

Review result: no defects of severity low or above in MyrmexToken. One informational note recorded.

What I covered (Execution Trace, Periphery and First Principles guides, applied to every entry point):

• transfer / transferFrom: zero-address and balance guards precede the unchecked arithmetic. Self-transfer and self-transferFrom keep the balance because the credit re-reads storage. Unlimited allowance is left untouched. Failures revert atomically, so no partial state.
• burn: only the caller's balance, bound-checked before the unchecked decrement of balance and total supply.
• permit: inclusive deadline, nonce folded into the signed struct, low-s and v in {27, 28} enforced, zero recovered address and non-owner rejected, chain-id-aware domain separator. Replay, tamper, expiry and zero-owner inputs all revert.
• approve: plain overwrite with zero-spender guard.
• Constructor and surface: whole supply minted once to the constructor's sender, no arguments, no roles, no receive or fallback, no DELEGATECALL, CALLCODE or SELFDESTRUCT.
• Invariant: a stateful fuzz run of 128,000 calls across transfer, approve plus transferFrom and burn kept the sum of balances equal to total supply and never above the initial supply.
• Static-analysis leads: the timestamp comparison is the intended EIP-2612 semantics, malleability is closed by the half-order bound, and the large literal is the specified supply constant. None is a defect.

The one note (info): a zero-amount transferFrom emits an Approval event naming the owner and caller even though the owner never approved anyone. No storage or balance changes, so no loss. The reproduction is in the findings file.

Coverage rows are written for all five listed entry points plus the invariant, constructor and static-analysis leads. Scratch tests live under test/scratch/ and nothing else in the tree was changed.

The review is complete and the findings file is written. The tree is unchanged apart from the ignored findings file and build cache.

Result: no math, boundary or numerical-gap defect in MyrmexToken. The token has no division, no fixed-point scaling, no downcast, no external call, no payable path and no bytes decoding, so most items in the three guides have no surface here. What remains is the unchecked arithmetic, the supply invariant and the permit signature bounds, and all of it holds.

What I verified, with a scratch Foundry suite (22 tests, since deleted) on top of the existing 43:

• Supply invariant. A stateful invariant over transfer, transferFrom and burn across four actors ran 128,000 calls with zero reverts and never broke sum of balances equals total supply equals 1e27 minus burned.
• Unchecked blocks. Every subtraction is preceded by a balance or allowance check, and balances cannot exceed the fixed 1e27, so none of the unchecked operations can wrap. Max-uint transfer and burn revert cleanly. Self-transfer preserves the balance because the destination slot is read after the source write.
• Allowance edges. Max is unlimited and untouched, max minus one is finite and decreases, and no fuzz input underflowed.
• Permit bounds. The half-order constant equals floor(n/2) exactly. s at the half order passes the guard, s one above is refused before ecrecover. v outside 27 and 28, r or s zero, r at or above n, a wrong chain id and a tampered value all revert. A failed permit does not consume the nonce. Deadline zero at time zero works, deadline max never expires.
• Launch arithmetic. The 10%, 80% and 10% basis-point splits divide 1e27 with no remainder, so the launch flows carry no dust.

The only item reported is one info-level note: a zero-amount transferFrom lets any caller emit an Approval event for any owner and spender pair with no state change. The emitted value equals the real allowance, so nothing is misled and no funds move. The reproduction is in the file.

The three static-analysis leads were checked and not promoted: the timestamp comparison is the standard EIP-2612 deadline, signature malleability is blocked by the low-s and v checks, and the large literal is the correct half-order constant.

Coverage in the findings file answers all five entry points plus three invariant rows: four hold, transferFrom carries the info finding.

The findings file is in place and is hidden from git only by the workspace's own exclude rule, which is expected. The review is complete.

Result: no defects found in the assigned area. The findings file at the repository root holds an empty findings list and a 12-row coverage record, with every one of the five listed entry points marked holds.

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

• Conservation. The supply is written only in the constructor and in burn, and balances only move between two parties or shrink with the supply. An invariant fuzz harness driving transfer, transferFrom, approve, permit and burn across seven actors for 16,000 random calls never broke sum(balances) == totalSupply or totalSupply == initial - burned.
• Unchecked arithmetic. Every unchecked subtraction follows a balance or allowance bound check. The unchecked add to a receiver is bounded by the 1e27 supply, so no path can mint by wrapping.
• ERC-20 and ERC-2612 compliance. Self-transfer, zero amounts, whole-supply round trips, max allowance, self transferFrom, and transferFrom from the zero address all behave as specified. Permit refuses expired deadlines, tampered fields, other-chain and other-contract signatures, high s, bad v, zero r or s, and replays. The half-order constant equals n/2 exactly and the supply literal equals the README's manifest string exactly.
• Launch flows. The token has no fee, hook, callback or external call, so the swarm share, the pool seed via sync/transfer/settle, trader buys and sells, and the remainder all move exactly what they say.
• Static-analysis leads. All three are refuted: the timestamp comparison is the intended deadline check, malleability is blocked by the low-s guard plus the nonce, and the large literal is correct.

Notes that are not defects, for the author's awareness:

• A permit submitted by a front-runner makes a bundled permit-plus-transferFrom call revert, though the allowance still lands. This is inherent to EIP-2612 and is handled on the integrator side.
• transferFrom emits an Approval event on a finite allowance decrease, which EIP-20 allows but OpenZeppelin v5 no longer does.
• Tokens sent to the token contract itself are irrecoverable, as the README already states.

Not reached: bytecode determinism and explorer verification, which belong to another specialist and the deployer. The scratch tests I used as evidence were removed after running, as nothing under that directory is kept.

I found nothing in MyrmexToken that blocks the launch. The only finding is one info-level item, and the findings and coverage are in .imd-findings.json.

The specialist findings: audit_flow and audit_math reported the same problem, so I merged them into that one info finding at src/MyrmexToken.sol:220. Anyone can call transferFrom(owner, to, 0) and the token emits an Approval(owner, caller, allowance) event even though the owner approved nothing. I confirmed this with a scratch Foundry test, then deleted the test. Nothing in storage changes and no tokens move. OpenZeppelin v4 behaves the same way and EIP-20 allows it, so it is only a stray event. It carries no proof, since proofs are only required for critical and high findings.

Static-analysis leads, all dropped:

• Timestamp check in permit: this is the standard EIP-2612 deadline check.
• ecrecover malleability: the code already refuses high-s signatures, any v other than 27 or 28, and a zero recovered address.
• Large number at line 41: it is the correct supply, 10^27.

My own read found nothing more:

• Supply: it is fixed. The constructor is the only mint, there is no owner or privileged role, and burn only touches the caller's own balance.
• Transfers: they move the exact amount, with no fee or hook. So the factory's transfer to the distributor, the pool seed and swaps all arrive whole.
• Balances: every unchecked subtraction is guarded by a balance check first.
• Manifest: launch.json matches the code. It has no constructor arguments, the supply is 1e27 and decimals are 18. The deployed contract is about 4.3 KB, well under the size limit.

Coverage: all five entry points are answered. approve, burn, permit and transfer hold; transferFrom is marked finding because of the info item. I also added two rows: one for the fixed-supply rule and one for the manifest matching the code.

All 105 of the repo's tests pass, and the scratch test was the only file I added; the working tree is clean.
