Implemented HIC, HandlerDesk, soulbound HandlerCards, on-chain artwork, ABI exports, and deployment/agent documentation.

Verified: forge build, forge fmt --check, and forge test — 45 passed, including real v4 integration and stateful accounting checks.

Assumptions and operational responsibilities are documented in README.md.

The review is complete and .imd-findings.json holds the result. No source file was changed and the scratch tests I used were removed.

Outcome. The control flow of HandlerDesk, HandlerCards, HandlerArt and LaunchToken holds against the Execution Trace, Periphery and First Principles checklists. I found no defect that loses or misroutes card funds. Three low or informational findings are recorded, each with a concrete reproduction.

Findings written

• Low, buyAndBurn slippage. Any caller may burn the whole accrued reserve with a 1 wei minimum, so a same-block sandwich recovers the IMD meant to be burned. With a 0.5 IMD reserve and a manipulated rate, only 500 wei of HIC reach the dead address. The README already documents this as accepted MEV exposure, so the judge decides whether the design stands.
• Low, mint price ceiling. mint pulls whatever mintPrice is at execution time and has no caller-side bound. A holder with a max approval pays 2 IMD instead of 0.2 if the owner's price change lands first. Owner-bounded and documented, so a trust assumption, reported so the frontend approves the exact price.
• Info, documentation. docs/deployment.md states a literal owner address that the approved workflow never names. The manifest plan correctly uses the symbolic owner reference, so nothing deploys wrong.

What I verified as holding. The swap path (unlock, callback authentication, exact-input delta checks, sync, settle, take) traced against the vendored real Uniswap v4 PoolManager. The coin balance and position quantity stay equal for every non-IMD coin, so proportional basis removal cannot divide by zero. The IMD solvency invariant holds through every credit, debit and fee split. Daily cap and per-trade checks cannot underflow when rules are lowered. The soulbound override blocks every transfer and burn. Exported ABIs match the compiled artifacts, all four runtimes fit EIP-170, and a linear opcode scan finds no forbidden opcodes including the HandlerCards creation code embedded in the Desk. Build, the 45 project tests and the formatting check all pass.

Static-analysis leads. The reentrancy lines are covered by the guard with the callback flag cleared before external calls. The divide-before-multiply in the date routine is the standard civil-from-days algorithm. The encodePacked hash-collision line is concatenation, not hashing. None became a finding.

Coverage. All 22 listed entry points have a row, 19 hold and 3 point at findings, plus 5 rows for invariants, the renderer, the ABI exports and the manifest plan. Nothing was left unreached.

The review is complete and the findings file is in place. The working tree is clean apart from the untracked findings file.

Outcome. The math in my area holds. One low-severity defect is reported, with a concrete reproduction on the vendored Uniswap v4 core.

What I checked, in depth

• Fee and basis arithmetic in HandlerDesk. Buy fee rounds down and is zero below 400 wei, which is dust. Cost basis is conserved across partial sells, and realised P&L equals proceeds minus cost. Rounding the removed basis down cannot flip a win into a loss or the reverse, because comparing an integer against a floored value is exact.
• Daily cap. The comparison cannot underflow, is exact at the cap, handles a cap of max uint256, and resets correctly at the UTC day boundary.
• Swap boundaries on the real v4 core. One-wei input reverts cleanly, exhausting concentrated liquidity reverts with PartialFill rather than filling short, and the price-limit constants are exactly MIN+1 and MAX-1.
• HandlerArt rendering. The Gregorian date routine matches nine known dates including leap days and century boundaries. Signed rendering handles the minimum int256. The Slither divide-before-multiply and Aderyn encodePacked leads are false positives here.
• ABI documentation. Re-running the export tool produced byte-identical files. Constructor argument order in the deployment doc matches the source.

The finding (low). The win record is a per-sell counter with no minimum size. After one favourable price move, an agent sold one millionth of a coin fifty times and the card showed 50 wins, 0 losses and a 100% win rate for a realised gain of 0.00002 IMD. Holder withdrawals also remove basis without recording a loss. This contradicts the brief's "nobody can fake it" claim, though the README acknowledges the bias. Any fix changes the approved rule that every partial sell counts, so it is flagged as a scope decision.

Coverage. All 22 listed entry points have rows, plus four invariant rows. Not reached: the economic question of whether the factory's one-sided HIC liquidity range could ever be exhausted by the lump-sum burn, which would strand the burn reserve. That depends on the factory's seeding range, which the tree does not state.

The review is complete. Findings and coverage are in .imd-findings.json. No tracked file was changed; the two scratch tests live under the gitignored test/scratch/.

Outcome. The permission model holds. I traced every one of the 22 entry points against the Access Control, Trust Gap and Asymmetry guides and found no missing guard, escalation path, or asymmetric write. Soulbound transfers revert for existing ids and fall into OpenZeppelin's nonexistent-token revert for unminted ids. Only the immutable Desk can mint cards. Holder and agent authority are cleanly split, with freeze blocking both trade directions. Ownership uses two-step transfer with renounce disabled, and the owner can never be zero. The pool callback is bound to the pinned PoolManager, a pending flag, and a data hash that is cleared before any external call.

Findings written (1 low, 4 info):

• Low: mint has no caller price bound. A price change mined before a pending mint charges whatever the storage price is, up to 2 IMD against a quoted 0.2 IMD, with half paid to the owner. Verified with a scratch test on the fixture. Suggested fix is a maximum-price argument on mint.
• Info: buyAndBurn is sandwichable because its only slippage guard is the caller's own minimum. The README already accepts this; card balances are never at risk.
• Info: the deployment doc hard-codes an owner address that the approved workflow never names. A manifest copying the hex instead of $owner would install an unauthorized fee recipient and price setter.
• Info: the Desk pins the HIC pool key to IMD pairing, fee 12500, spacing 60 and the launch hook. A manifest pairing with ETH or other parameters makes every mint revert forever.
• Info: a holder acting as their own agent can manufacture wins with zero-fee 399-wei buys and a self-made price move. Verified with a scratch test. The README acknowledges tiny-trade bias; recorded against the workflow's "nobody can fake it" claim.

Coverage. All 22 entry points answered, plus two invariant rows: 21 hold, 3 point at findings, none unreached. The existing suite of 45 tests passes on the current tree.

The review is complete. The findings file is written and the working tree is otherwise untouched (git status shows nothing besides the ignored findings file).

Outcome: no critical, high or medium defects in the economics area. The Desk's value flows hold under every failure mode I checked from the Economic Security, Invariant and Flow Gap guides, including against the real vendored Uniswap v4 PoolManager.

What was verified

• Conservation. Desk IMD balance equals total card liability plus the burn reserve, and coin balances equal liability, through buys, sells, withdrawals, mints and burns. Credits are measured from balance deltas, exact-input fills are enforced, and short settlements revert.
• Fee split and cost basis. The 0.25% fee is taken from the IMD side on both directions, half to owner and half accrued. Cost basis, proportional removal, win/loss and P&L match the brief.
• Caps and timers. Per-trade and UTC-day limits cannot be bypassed or reset by rule changes. The burn interval resets only on a successful burn.
• Custody. Only holders withdraw, only to themselves. Agents have no path to move value out except by trading on initialized IMD launch pools, bounded by the holder's caps.
• Callback and reentrancy. The hook address carries only the beforeInitialize flag, so swaps never call the hook. The unlock callback is bound to the Desk's own unlock by hash. All state-changing entry points are guarded.
• buyAndBurn MEV. I ran a full sandwich on the real pool with minOut of 1. The attacker lost about 1,212 IMD to divert about 1.3 IMD of burn, so the README's MEV concern is not an exploitable path at the 1.25% pool fee.

Findings written (1 low, 4 info)

1. Low. Win rate and realized P&L are curatable: a holder withdraws losing coin positions unrealized and sells only winners. Reproduced on the real pool with a hidden 56% loss and a recorded 100% win rate. Documented in the README, but it contradicts the brief's "nobody can fake it" and the leaderboard sort key.
2. Info. The trades counter includes buys, so the badge's TRADES disagrees with W plus L and the brief's example.
3. Info. The Desk fee rounds to zero for IMD legs below 400 wei. Dust only.
4. Info. mint has no caller-side price bound, so an owner price change racing a max-allowance mint charges up to 2 IMD. Trust assumption.
5. Info. Token name casing differs between the brief's final "Token name" line and the contract.

Coverage. All 22 listed entry points have a row, plus three invariant and manifest rows. None are unreached. No launch.json exists in the tree yet, so the constructor check was against the deployment handoff in docs, which matches the Desk constructor and ordering.

Added failure-path, fuzz, accounting, withdrawal, and fixed-supply invariant tests, plus additional local Uniswap v4 integration cases.

forge build and offline forge test pass: 81 passed, 0 failed, 0 skipped.

Only test/ changed. No confirmed defects found. Live-chain fork validation remains outstanding.

I found no defect that blocks the launch. I kept four findings: one low and three informational. Every one was reproduced in a scratch Foundry test that passed on the current code. They are written to .imd-findings.json along with a coverage row for each of the 22 entry points. I removed the scratch tests afterwards and changed no other file.

Deployability: this holds.

• HandlerDesk is 17,553 bytes of creation code and 12,400 deployed, well under the 49,152 and 24,576 limits.
• No constructor calls a contract that already exists.
• I ran the protected opcode scan on the deployed Art, Desk and Cards code (the Desk creates Cards itself). None contains DELEGATECALL, CALLCODE or SELFDESTRUCT.
• launch.json uses only schema keys and pairs with IMD in lowercase at fee 12500 and tick spacing 60. HandlerDesk's arguments [$owner, $token, $contract:HandlerArt] match its constructor order.
• The exported ABIs match the compiled ones, and the full suite passes (81 tests).

Findings kept (duplicates merged):

1. Low: anyone can trigger buyAndBurn with a minimum of 1 wei (src/HandlerDesk.sol:291). The caller can move the HIC/IMD pool price first and then trigger the burn, which swaps the whole reserve. Reproduced: a 0.5 IMD reserve burned for 500 wei of HIC and the reserve was reset to 0. Card balances are unaffected; the loss is burn value owed to HIC holders. Merges audit_flow #1 and audit_permissions #2.

2. Info: mint has no maximum price (src/HandlerDesk.sol:159). A minter with a standing allowance pays whatever the price is when their transaction lands. Reproduced: an owner price change to 2 IMD mined first took 2 IMD instead of the quoted 0.2. The owner is trusted and the range is the one the brief specifies, so I treat this as a trust assumption for the frontend to handle by approving the exact price. Merges three specialist reports.

3. Info: the win record can be inflated (src/HandlerDesk.sol:274). The code follows the brief's rule exactly, yet the brief's claim that "nobody can fake it" does not hold:

   • 50 tiny sells after one price rise recorded 50 wins and 0 losses.
   • Withdrawing a losing position records no loss.
   • Trades under 400 wei pay no fee.

   Changing this would change the approved rules, so it is the requester's decision. Merges four specialist reports.

4. Info: trades counts buys as well as sells (src/HandlerDesk.sol:248). The badge shows TRADES 2 next to one win or loss, while the brief's example counts only closed trades.

Dropped:

• Owner address in docs/deployment.md: the manifest correctly uses $owner, and I can't show the address is wrong.
• Pool-key dependency: the manifest already matches what the Desk expects.
• Token-name casing: the contract and the manifest agree on "Handlers In Control", which is the brief's main spelling.

Static-analysis leads, all false positives:

• Reentrancy: blocked by nonReentrant and the single-use callback check.
• Divide-before-multiply in _date: that integer division is how the date algorithm is meant to work.
• Strict equality: used on purpose to reject tokens that skim transfers.
• abi.encodePacked collision: the packed bytes are never hashed.

The other 18 entry points hold. I also added two invariant rows, for deployability and launch.json.

Implemented the frontend, static export, deployment manifest, and documentation.

Validation passed: build, typecheck, 11 core tests, Chromium/WebKit interaction tests, and 16 design checks. All deployment, ABI, and asset hashes match. Export size: 887 KB.

Commit blocked: Git could not create .git/index.lock because .git is read-only. All deliverables remain in the working tree. No live transactions were broadcast.

Saved 4 medium findings in .imd-findings.json. Website files remain unchanged.

• Bug: Wallet consent incorrectly says no account is shared.
• Bug: Automatic refresh removes balance rows and moves the focused deposit input offscreen.
• Fidelity: Mint confirmation omits the requested print animation; it runs later, roughly 2,700px below the mobile viewport.
• Accessibility: Empty amount-field boundaries measure 1.79:1, below the applicable 3:1 non-text contrast requirement.

Each finding contains an exact source citation, replacement or repair, and measured reproduction.

The isolated rebuild matches the submitted export byte-for-byte. Deployment configuration, pinned ABIs and all 21 asset hashes pass verification. Core tests passed 11/11, WebKit interactions 9/9, observability 7/7, and keyboard checks passed. Chromium interactions passed 9/9 after correcting a temporary test-harness timing race. Live chain verification and quote simulation succeeded; transactions used simulated wallets.

The visual idea is a trading-permission desk expressed through printed, off-white agent badges hanging from black lanyards.

Coverage below consolidates the duplicated workflow text. Contract entries describe the preserved implementation, rather than a new Solidity audit.
