Delivered five 1024×1024 PNG options in logos/ and the selected icon at artifacts/logo.png.

Built-in image generation drew all five drafts; all were retained. Option 2 reads best at 32 pixels. The alternatives’ lettering, rim, or finer details made them less suitable for the launch icon; logos/README.md records the review.

Also completed the SFPT token, manifest, and offline Foundry project. forge build and all 23 tests pass, including Uniswap v4 integration. Live-chain fork validation was not run.

Implemented the site in site/ and production export in dist/, including the 3D den, live-data handling, calculator, guide, sharing, docs, and 404.

Passed export, typecheck, browser/accessibility checks, and all 23 Foundry tests. Protected files remain unchanged; submission files fit under 8 MiB.

Design, validation, and publishing instructions are documented. Live deployment data remains pending.

Completed using the existing compliant token and exact launch manifest. Added two regression tests and clarified deployment responsibilities. Protected configuration and dependencies remain unchanged.

Validation passed:

• forge build
• forge test — 25 tests passed
• forge fmt --check

Local Uniswap v4 integration passed. Live mainnet and launch-factory hook validation were not run.

Implemented only under test/: expanded failure-path tests, stateful balance/allowance invariants, and real local Uniswap v4 swap, fee-collection, and rollback checks.

forge build and forge test pass: 36 tests, default 256 fuzz runs, and 2,048 invariant calls.

Live mainnet fork testing remains unperformed.

Updated launch.json to accurately describe the accepted token, preserving the required pool and economics values.

Manifest and constructor ABI checks passed. forge build succeeded; forge test passed all 36 tests.

Only launch.json changed outside disposable test scratch files.

I found no defects in the math, boundary or numerical-gap areas of src/SFPTToken.sol. .imd-findings.json has an empty findings list and a coverage row for each entry point.

Tests: forge test passes all 36 tests, including the invariant suite and the Uniswap v4 tests against a real PoolManager in both currency orders. I couldn't run the protected launch test (Token.protected.t.sol) here: it needs the deployer's environment variables and launch support contracts that aren't in this repo. I read how it buys and sells instead.

What I checked:

• Tax formula: the tax is value / (10_000 / 200), which is exactly value / 50 with nothing lost to rounding. It can't overflow because there's no multiplication, and value - tax can't underflow. Tax plus what the buyer gets always equals the amount sent, so supply never changes. At the maximum possible amount the call reverts for insufficient balance, not overflow.
• Rounding down: a buy under 50 wei pays no tax, and the tax always rounds down. This is intended, tested by test_RoundingAtSmallestTaxBoundary, and stated in the manifest notes. The most anyone can save is under 1 wei per transfer, and each transfer costs far more in gas. I didn't report it.
• Exempt paths: sells, the pool seed, PoolManager-to-itself transfers, wallet-to-wallet, treasury and zero-amount transfers all move the full amount untaxed. The pool's balance accounting therefore always balances. The protected test sells back the trader's actual balance, so the 2% buy tax doesn't break its sell step.
• Allowances: transferFrom spends the full amount from the allowance. A failed buy reverts completely, leaving no tax or allowance change behind.
• Opening price: pool.initialPrice matches the price implied by the economics (2,500 IMD market cap over 1e27 units) exactly, and it is within the pool's valid range.
• Static analysis: the Aderyn "large numeric literal" warning is about style, not correctness. Slither reported nothing.

What I didn't cover: none of the three guides was skipped. Their checks for share prices, interest, casts, bit packing, oracles and payable functions don't apply, because the contract has none of those: it is only the token and its tax logic.

The review is complete. The findings file is in place at the repository root, the scratch test is removed, and no tracked file was changed.

Outcome: one low finding, no permission defects. The token has no owner, roles, initializer, proxy, receive or fallback. Its whole state-changing surface is the three OpenZeppelin v5 entry points, and every parameter is a compile-time constant. The 2% tax is keyed on the ERC20 source address, so every launch flow the factory performs moves exactly what it says, buyers via the normal take path pay exactly floor(amount/50) to the treasury, and partial tax debits roll back atomically. The existing 36 tests pass, including the real-PoolManager seed, buy and sell in both currency orders, and the launch manifest is schema-valid and consistent with the code.

The finding is a trust-gap item at the economics and asymmetry seam. Uniswap v4 lets a swapper settle a positive delta as ERC-6909 claims inside the PoolManager instead of an ERC20 take, and later pay a sell by burning those claims. Neither step calls the token, so the treasury receives nothing. I reproduced it against the vendored PoolManager at the mandated address with the brief's price and seed.

I rated it low rather than medium because the mechanics spec defines a buy as a transfer from the PoolManager, so the code conforms to the letter, and a token alone cannot observe a claims-settled swap. The actionable remedy inside this project is documentation. A hook-based launch would be a requester-level design decision.

Coverage. All three listed entry points hold. I also recorded rows for the no-privileged-role invariant, the launch-flow conservation invariant, the tax-reaches-treasury invariant (marked finding), and the manifest. Not reached: a live Ethereum fork against the production factory, its initialization-guard hook and the Universal Router, which this offline environment cannot run.

The review is complete. .imd-findings.json holds one substantiated finding and a seven-row coverage record, and no repository file was changed.

What I audited. The token is a 31-line OpenZeppelin v5 ERC-20 override whose only logic is the tax branch in _update. I traced all three entry points through the base contract and the real vendored Uniswap v4 PoolManager, ran the existing 36-test suite (all pass, including the invariant campaign), checked the launch manifest against the schema and economics, and confirmed the doc copies under dist/ and site/ are byte-identical to the source.

Finding (medium). The 2% creator tax fires only on an ERC-20 transfer whose sender is the PoolManager. Uniswap v4 flash accounting lets a buyer settle the SFPT they bought as ERC-6909 claim tokens via PoolManager.mint instead of take, hand those claims to anyone inside the manager, and later sell by burning them. No SFPT transfer ever happens, so _update never runs and the treasury receives nothing for a full buy, hold, sell cycle. Multi-hop routes with SFPT as the intermediate currency behave the same way. I reproduced this with a scratch Foundry test against the real PoolManager at its mainnet address; the claims-settled round trip pays zero tax while the identical buy via take pays exactly gross/50. The code matches the literal wording of mechanics spec M1, but not the "every buy pays 2%" guarantee the brief and the published site state. There is no token-side fix that keeps sells and seeds untaxed, so I framed it as a product decision: document the limitation precisely, or change the mechanics outside this brief. I did not attach it as a proof test because no token change can make it pass.

What holds. Approve, transfer and transferFrom behave as intended on every path I traced: tax rounds down and never exceeds value, the tax leg and net leg revert atomically on a short balance, zero-address recipients are rejected before the override runs, PoolManager self-transfers and transfers to the treasury conserve value, allowance is spent on gross, and transfers into the PoolManager arrive whole so v4 sync and settle balance in both currency orders. Supply is minted once to the deployer with no mint, burn, owner, delegatecall or selfdestruct path. The manifest keys, supply, addresses, pool parameters and economics are exact, and the initial price matches the 2500 IMD opening cap.

Not reached. A live Ethereum fork against the production factory, hook and router remains owed, as the repository's own test README already notes.

The findings file is in place and the harness deliberately excludes it from git, so the working tree is otherwise untouched. The review is complete.

Outcome: one medium finding, no critical or high. The token's arithmetic, conservation, launch flows and manifest all hold.

Finding 1 (medium): the 2% creator tax can be avoided through Uniswap v4 claim tokens. The tax lives in the ERC-20 transfer path and fires only when SFPT leaves the PoolManager as an ERC-20 transfer. Uniswap v4 lets a trader receive swap output as ERC-6909 claim tokens inside the PoolManager and pay later swap input by burning them. A buy into claims followed by a sell by burning claims is a full economic round trip that never triggers the override at src/SFPTToken.sol:22. I reproduced this against the real vendored PoolManager with the pool seeded as the launch would seed it. The same 1 PAIR buy paid the treasury about 7,850 SFPT via take and 0 via mint. Claim tokens are also transferable inside the PoolManager, so an untaxed secondary market is possible. The description states plainly that the token alone cannot fix this and the factory controls the hook, so the requester's choice is to document the limitation or move the tax into a swap hook outside this repository. The failing Foundry test is embedded as the proof.

What holds in the economics area:

• Supply conservation and PoolManager balance consistency under the tax split, including failed-transfer atomicity.
• All launch flows arrive whole, since only transfers originating at the PoolManager are taxed.
• Seed, buy and sell settle with zero outstanding deltas in both currency orderings.
• Rounding is floor division by 50 with no overflow; the untaxed sub-50-wei window is dust and not farmable.
• launch.json has exactly the six required keys, the economics copied verbatim, and an initialPrice that equals the derived sqrtPriceX96 to the digit.

Documented but not defects: LP withdrawals, LP fee collection and protocol fee collection from the PoolManager are taxed 2%, consistent with the spec's literal definition of a buy and stated in the README.

Coverage: all three entry points have rows, two pointing at the finding and approve marked holds, plus eight invariant rows. Static analysis leads were only a large-literal style note, which I left out.

The review is complete. The findings file is at .imd-findings.json and no other file in the tree was changed.

Outcome. The token holds. All three specialists reported the same root cause, which I reproduced and merged into one low-severity finding. I found nothing else in my own pass.

The one finding (low). The 2% tax fires only on ERC-20 transfers out of the PoolManager, at src/SFPTToken.sol:22. Uniswap v4 lets a buyer settle swap output as ERC-6909 claims through PoolManager.mint and pay a later sell by burning them, so SFPT never leaves the manager as an ERC-20 and the treasury receives nothing. My scratch harness showed this with the real vendored PoolManager.

I calibrated it to low rather than the specialists' medium because mechanics spec M1 is authoritative and literally defines a buy as a transfer from the PoolManager, which the code implements exactly. No holder loses funds and settlement always balances. The gap is between that mechanism and the site's "2% buy tax" headline. No token-side change can close it while keeping sells and the seed untaxed, so the remedy is one documenting sentence in the manifest notes and the site FAQ. I attached no proof file, since a fail-then-pass test cannot exist for a limitation the token cannot fix.

What I verified myself.

• Build and all 36 committed tests pass offline with solc 0.8.26, cancun and no bytecode hash.
• No gitlinks under lib/, so the verifier's networkless build will find every dependency.
• The constructor mints exactly 1e27 to msg.sender, there are no admin, mint, burn or upgrade entry points, and the runtime has no delegatecall or selfdestruct.
• Every launch flow the protected test exercises (seed, swarm share, claims, remainder, sells) moves the full amount, and a take-settled buy pays exactly floor(amount/50) to the treasury.
• launch.json has exactly the six required keys, lowercase addresses, 886-character notes, and an initialPrice that matches the derived square-root price from the economics.

Coverage record. All three ABI entry points are answered, plus six invariant rows. The approve row holds. The transfer and transferFrom rows cite finding 1, since both route through the taxed _update path whose scope the finding describes.
