The deliverable is complete and verified.

What was built

• src/IDMToken.sol: contract IDMToken, OpenZeppelin v5.7.0 ERC20, name "Intelligent Dance Markets", symbol "IDM", 18 decimals. The constructor takes no arguments and mints the full 1,000,000,000 IDM once to msg.sender. There is no owner, mint, pause, blocklist, fee or burn hook, so every launch flow moves exactly what it says.
• foundry.toml: solc = "0.8.26", evm_version = "cancun", optimizer at 200 runs, bytecode_hash = "none", ffi off, no filesystem permissions, remappings for the two vendored libraries.
• lib/forge-std (v1.17.0) and lib/openzeppelin-contracts (v5.7.0) vendored as plain files from release tarballs. No submodules, no .git directories, so the offline verifier can build.
• script/DeployIDMToken.s.sol: an argument-free deploy() helper for local review, tested directly. The launch itself deploys from creation code through the factory and does not use it.
• README.md: assumptions, the manifest values for the launch, an empty "After launch" section (nothing is owner-settable), operational responsibilities and the test inventory.

Tests cover the success and failure paths of transfer, approve and transferFrom with ERC-6093 errors, the one-time mint with a single Transfer event, the 10/70/20 launch split through a CREATE2 factory stand-in, the swarm share arriving and being claimable whole, all common mint, ownership, pause, freeze, blocklist and seize selectors reverting from both a stranger and the factory, an opcode scan for DELEGATECALL, CALLCODE and SELFDESTRUCT, and four fuzz properties on supply conservation and allowance bounds.

Not done, by the rules

I did not run git commit, since .git/ is off limits. All deliverable paths are untracked in the working tree and ready for the harness to commit. The untracked dotfiles such as .bashrc and .gitmodules are sandbox device mounts that predate this task and are not mine.

I found no defects in IDMToken under the Economic Security, Invariant and Flow Gap guides, so .imd-findings.json holds an empty findings list plus a coverage record.

What I checked

• The token itself: src/IDMToken.sol is the vendored OpenZeppelin 5.x ERC20 with nothing overridden. It mints TOTAL_SUPPLY = 1_000_000_000 * 10**18 to msg.sender once, in the constructor. It has no other mint or burn path, no owner, no pause or blocklist, and no fee, burn or hook on transfer.
• The library code: I read the vendored OpenZeppelin ERC20.sol itself (transfer, approve, transferFrom, _update, _approve, _spendAllowance), not just the import, and it has no local changes.
• Economic invariants:
  • The supply is fixed and cannot grow after launch.
  • No privileged call can move or freeze anyone's balance.
  • Every transfer moves exactly the amount asked, so the launch flows (factory to distributor, distributor to claimant, the pool seed, and buys and sells) arrive whole. That is what the protected launch test requires.
  • decimals() returns 18, matching the brief.
• Static-analysis leads: Slither reported nothing. Aderyn's one line, "large numeric literal" at line 26, points at the supply constant, which is correct as written.
• Tests: the repository's own suite passed locally, 38 of 38. I did not run the protected launch tests, because they need launch settings (supplied by environment variables) that only exist at launch time; I read them instead.

Coverage rows: all three entry points, approve, transfer and transferFrom, are marked holds. I added four invariant rows (fixed supply, no privileged hand, exact flows, decimals), all also holds.

I left out one known general ERC-20 trait: changing an existing allowance with approve can be front-run by the spender. That is standard ERC-20 behaviour, not an economic defect in this token.

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

Validation passed against the compiled constructor ABI. forge build succeeded; all 38 tests passed with the supplied fuzz seed.

Only launch.json is included in the deliverable.

The review is complete. The findings file is written and valid, the scratch directory is removed, and the working tree holds nothing new beyond the required output.

Result: no defects found in the assigned area. .imd-findings.json holds an empty findings list and nine coverage rows, all holds.

What the token is. src/IDMToken.sol is OpenZeppelin v5.7.0 ERC20 with one constructor line minting the constant supply to the deployer. The compiled ABI exposes only the standard ERC-20 surface plus four public constants, with no payable function, receive, fallback, external call, sentinel branch, or bytes decoding. That leaves very little math to audit, and what exists is sound.

What I verified, with concrete inputs run under Foundry:

• Supply constant. The expression at line 26 constant-folds to exactly 1e27, matching the manifest's totalSupply. The aderyn "large numeric literal" lead is cosmetic.
• Transfer boundaries. Amounts of 0, exact balance, balance plus one, and type(uint256).max behave correctly. The over-balance cases revert with ERC20InsufficientBalance and nothing wraps, because the checked guard runs before the unchecked subtraction. Self-transfer does not double count. A four-party fuzz conserved the sum of balances across 512 runs.
• Allowance boundaries. Max allowance is never decremented, max minus one is decremented exactly, allowance zero with value zero passes as the standard specifies, and an infinite allowance still cannot move more than the owner's balance. Self-transferFrom does not double count.
• Launch split. 10%, 70% and 20% of 1e27 all have zero remainder and sum to the supply. The 7e26 pool share fits the Uniswap v4 int128 delta domain. The token takes no fee, so every launch flow arrives whole.
• Decimals. decimals() returns the OZ default 18 and matches the DECIMALS constant and the manifest.
• Bytecode. Runtime is 2200 bytes and the project's opcode-scan test confirms no DELEGATECALL, CALLCODE or SELFDESTRUCT.

The project's own 38 tests pass with the verifier's fuzz seed.

One maintenance note, not a finding. The DECIMALS constant feeds TOTAL_SUPPLY but is not wired into decimals(), which still returns OZ's hardcoded 18. Both agree today, so there is no failing input. A future edit to one without the other would silently desynchronise the supply math from the reported decimals. I recorded this in the coverage row rather than as a finding, since the acceptance criteria require a concrete failing state.

Coverage limits. The MerkleDistributor's equal split of the swarm share and the deployer's price derivation live outside this tree, so any rounding dust there was not reviewable here.

The review is complete. The findings file is written, valid, and the working tree is clean (the findings file is gitignored, and I modified no repository files).

Summary

Assigned area: Access Control, Trust Gap, and Asymmetry for the IDM custom token.

Verdict: no defects in the assigned area.

IDMToken (src/IDMToken.sol) is a bare, fixed-supply OpenZeppelin v5.7.0 ERC20. It:

• overrides no ERC20 internals (_update, _approve, _transfer, _spendAllowance are all stock);
• declares no privileged surface — no Ownable/owner, no roles, no initialize, no second mint path, no pause/blacklist/freeze/seize/burnFrom, no delegatecall or assembly;
• mints the whole 1,000,000,000 × 10¹⁸ supply once to msg.sender in the constructor and takes no constructor arguments.

All three state-changing entry points are caller-scoped with no access-control asymmetry:

• approve sets only msg.sender's allowance;
• transfer moves only msg.sender's balance;
• transferFrom spends only the caller's granted allowance.

Because the Access Control / Trust Gap / Asymmetry guides concern privilege boundaries and role misconfiguration, and this token exposes no privilege whatsoever, there is nothing in-area to report. The one static-analysis lead (aderyn large-numeric-literal at line 26) is the intended compile-time supply constant — not a defect, and outside my area.

Coverage: all 3 compiled entry points verified as holds, plus two invariants (no privileged surface; constructor grants no lasting privilege). The findings file contains {"findings": []} with the full coverage record.

Added 20 edge-case/fuzz tests and three multi-actor invariants covering supply, balances, allowances, failure paths, and transfer liveness.

forge build and forge test pass with the required seed: 59 tests passed, including 32,768 invariant calls.

Only test/ changed. No implementation defects found.

The review is complete and .imd-findings.json holds the result.

Outcome: the IDM token is clean. All four specialists and the independent tester reported no findings, and I found no defect in the code myself. The file carries one info-level note and a full coverage record.

What I verified against the code

• src/IDMToken.sol is an unmodified OpenZeppelin v5.7.0 ERC20 whose constructor mints the whole supply to the deployer once. The only state-changing entry points are approve, transfer and transferFrom. There is no owner, mint path, fee, hook, receive or fallback.
• The five OpenZeppelin files the token compiles, plus the whole of forge-std, are byte-identical to the upstream v5.7.0 and v1.17.0 release tarballs. Other vendored OpenZeppelin files differ from upstream only by formatter reflow and are not imported.
• Compiled runtime is well under the size limits, has no link references, and contains no DELEGATECALL, CALLCODE or SELFDESTRUCT.
• The project's own 59 tests pass with the verifier's fuzz seed. My scratch test in test/scratch/Review.t.sol reproduces the floor's checks: CREATE2 mint to the factory, whole-amount swarm and claim flows, allowance semantics, failure reverts, and privileged selectors reverting from the deployer. All five pass.
• launch.json is schema-shaped and matches the contract: empty constructor arguments, 18 decimals, and a total supply that equals the contract's constant.
• The one aderyn lead, a large numeric literal, is the supply constant and is correct.

One info note kept. The README still says launch.json is deliberately absent from the tree, but the accepted manifest step has since added it. That is documentation drift only.

Coverage record. All three listed entry points are marked holds, with four extra invariant rows for the constructor mint, no supply growth or privileged controls, factory deployability, and dependency integrity. No files outside .imd-findings.json and test/scratch/ were changed.
