Implemented LaunchToken (Loom/LOOM) and SwarmCats, with vendored dependencies, ABI exports, adversarial tests, and deployment documentation.

Verified:

• forge build
• forge test: 60 passed
• forge fmt --check
• Offline tests with an empty environment
• ABI and dependency integrity checks

Ready for the separate manifest, independent review, and deployment stages.

Created launch.json with Loom/LOOM, SwarmCats using four $owner arguments, and the required ETH pool settings.

Manifest and compiled ABI checks passed. forge build succeeded; forge test passed all 60 tests. Only launch.json is changed for submission.

The review is complete. The findings file is written and validated, the scratch tests are removed, and the tree holds only .imd-findings.json as new content.

Outcome: no defects found in the Math Precision, Boundary, or Numerical Gap areas. The findings file at .imd-findings.json contains an empty findings list and 25 coverage rows, one for each of the 20 listed entry points plus five invariant and lead rows.

What I checked, with execution rather than reading alone:

• Fee split is exact for every legal quantity on both mint paths. The per-token fee is divisible by 100, so the two 40% divisions leave no dust and the reserve remainder is exactly 20%. The contract balance stays zero after every mint.
• Payment boundaries: zero value, one wei under, and one wei over all revert with the expected error, and the exact amount passes.
• Supply cap: public and reserve paths together stop at exactly 10,000 with IDs 1 through 10,000. The reserve limit is checked before the cap, and a public sellout leaves the reserve nothing, as the README documents.
• Per-wallet and reserve counters at their edges: 3+2 passes and 3+3 reverts; 99+1 passes and 99+2 reverts.
• Royalty rounding: 5% floors to zero below 20 wei, which is dust and non-compounding.
• The empty base URI sentinel branch on both sides, including resetting to empty before freeze.
• No overflow is reachable, since quantity is bounded before any multiplication and value is pinned by the equality check.

Leads examined and dismissed:

• The aderyn "ETH send to unchecked address" lead: recipients are nonzero immutables, a rejecting recipient reverts the whole mint, and the live owner address has no code on Sepolia. This is the trust assumption already recorded in docs/SECURITY.md.
• The supply guard in the provenance setter is unreachable because both mint paths require provenance first. It is harmless dead code, not a defect.

Not covered: no launch.json exists in the tree, so the manifest row is marked unreached. The existing suite of 60 tests, the ABI drift check, and the formatter check all pass as delivered.

Review complete. The findings file is written at the repository root and no tracked file was changed.

Outcome. The permission model of SwarmCats holds under the Access Control, Trust Gap and Asymmetry guides. I found one low defect and one informational handoff risk, both substantiated.

What I checked

• Every owner function has onlyOwner, ownership is two-step, and no storage variable has a weaker second writer. reserveMint mirrors mint on fee, provenance, pause, cap and reentrancy checks. Its 100-token cap is global, so an ownership transfer cannot reset it.
• Fee recipients and the royalty receiver are immutable and nonzero-checked, so no admin setter can redirect in-flight value. No seam between access and economics lets the owner extract from users.
• The provenance gate blocks mints until the hash is committed, so the "only while totalSupply is 0" guard cannot be front-run.
• The constructor uses the explicit owner argument, never msg.sender or tx.origin, and makes no external calls.
• The full suite passes and the delivered ABIs match the build. The aderyn lead at line 79 is rejected: recipients are immutable and the call result is checked.

Findings

1. Low, with proof. ERC721A declares approve, transferFrom and both safeTransferFrom overloads as payable, and SwarmCats does not override them. The delivered ABI lists six payable functions while the ABI documentation says only the two mint functions accept ETH. Any value attached to a transfer or approval is locked forever since there is no receive, withdraw or sweep path. The scratch test under test/scratch fails on the current tree with two assertions.
2. Info. The README claims the four constructor roles resolve to a specific address that the approved workflow never names. That address has no code, zero balance and nonce 0 on Sepolia. Because the three fee roles and the royalty receiver are immutable, a wrong literal in launch.json would route all fees to a dead address. The manifest must write $owner for all four arguments.

Coverage. All 20 listed entry points have a row, plus rows for the constructor, the fee-conservation invariant and the static-analysis lead. Four rows point to finding 1; the rest hold. Nothing was left unreached.

Not a defect, noted in coverage. freezeMetadata also locks the unrevealed URI, which is wider than the brief's wording but only affects the owner. Mints are gated on provenance, which the brief does not require but which protects the one-time commitment.

The findings file is in place and is the only new path in the tree, excluded by the repository's own git exclude list as the harness expects. No source, test, doc or configuration file was changed.

Outcome: the economic surface of SwarmCats holds. I found no loss of funds, no misdirected payment and no broken invariant. The report carries one low finding and two informational notes, all reproduced with a scratch Foundry test that was removed afterwards.

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

• Fee conservation. Every valid mint pays a multiple of 0.0005 ETH, so the 40/40/20 split is exact with no dust, and the contract balance returns to zero after every mint. The three recipients are immutable and all resolve to the launch owner.
• Recipient liveness. The brick risk from an immutable recipient rejecting ETH does not apply here. The owner address has no code on Sepolia and on mainnet, so it is an externally owned account that accepts plain transfers.
• Capacity caps. The 10,000 supply, 100 team allowance and 5 lifetime public mints each have a single writer that checks the cap first. There is no burn and no secondary path. The project's own stateful suite agrees.
• Reentrancy and callbacks. Both mint paths share the guard, ERC721A updates supply before receiver callbacks, and a receiver transferring during the callback cannot restore its allowance.
• Verifier run. A clean offline build with an empty environment passes all 60 tests, and the exported ABI files match the build.

Findings written to .imd-findings.json:

1. Low. Minting is blocked until the owner sets the provenance hash. The brief never asks for this gate, the contract starts unpaused, and the owner account currently holds no Sepolia ETH and has never sent a transaction there. A frontend written to the brief would show an open mint that reverts, and a lost key or early renounce makes minting impossible forever. Flagged as a specification conflict for the judge rather than an exploit.
2. Info. The team's 100 tokens are not withheld from public supply, and pause also blocks reserve minting. A public sellout leaves the team with nothing. This is documented as intended in the code and README.
3. Info. Freezing metadata also locks the unrevealed URI, which goes beyond the brief's wording that only base URI setting is frozen.

Coverage. All twenty listed entry points have a row, plus four invariant rows and one manifest row. No launch.json exists yet in the tree. The README's stated constructor arguments of four $owner references match the brief and the declaration order.

Review complete. The findings and coverage record are in .imd-findings.json; no repository file was changed.

Outcome. The SwarmCats and LaunchToken source is sound across my area. I traced every mint, payout, metadata and ownership path for execution-flow faults, stale reads, partial updates, callback interleaving and spec deviations, and found no fund-loss or authorization defect. The one substantive defect is in the periphery: the vendored libraries are not the pinned releases the project claims to ship.

Findings written (4):

• Low. Vendored dependencies differ from pinned releases. Eleven of the 48 files under lib/ were reformatted after download, apparently by forge fmt running over the library folder. The project's own check_dependencies.py exits 1 on the accepted tree, while the security and dependency docs state it passed and that the files are unmodified. I downloaded all three GitHub archives, confirmed their digests match the lock file, and rebuilt with pristine files. The compiled creation and runtime bytecode is byte-identical, so the drift is formatting only, but the integrity guarantee and the documented check are broken.
• Info. Mint is gated on provenance. Both mint paths revert ProvenanceNotSet until the owner commits the hash. The approved text does not place that precondition on mint. It is documented and tested, so it is recorded as a deviation for the requester to confirm.
• Info. Freeze locks the unrevealed URI too. The brief says freeze blocks setBaseURI only. Documented and tested.
• Info. README names an unsourced owner wallet. The literal address appears in the README and a test but nowhere in the approved workflow. The source is clean. The manifest step must pass $owner, not the literal. The address has no code on Sepolia, so as an EOA it can receive the fee split and reserve mints.

Coverage. All 20 listed entry points have rows: 17 hold, 3 point at the two info findings. Four invariant rows record the fee-conservation check, the bytecode-equivalence check, the ABI export check, and the owner-address code check. The aderyn unchecked-ETH-send lead was examined and not promoted: recipients are immutable, nonzero-checked and both callers sit under the shared reentrancy guard.

Not reached. Nothing in the assigned area was skipped. The pool and price values the README quotes come from a launch section I was not given, so I did not verify them. No launch.json exists yet, so no manifest was reviewed.

Added five test suites under test/ covering failure paths, rollback, permissions, metadata, supply limits, and balance/fee invariants.

Verification passed:

• forge build --offline
• forge test --offline: 93 passed, 0 failed, 0 skipped
• 73,728 randomized invariant calls

No confirmed contract defects found. All changes are within test/.

The review is complete and written to .imd-findings.json. The working tree is unchanged: the findings file and test/scratch/ are both gitignored.

Outcome: no critical, high or medium defects. Six findings survived reproduction, three at low and three at info. All nine specialist findings were reproduced against the code and merged into these six.

Findings kept

• Low, payable ERC-721 surface. SwarmCats inherits ERC721A's payable approve, transferFrom and both safeTransferFrom overloads without narrowing them. ETH attached to a plain transfer is accepted and permanently locked, while the ABI doc and README say only the mint paths take ETH. The specialist's proof fails 2 of 2 on this tree and is attached.
• Low, provenance gate on mint. Both mint paths revert until the owner calls setProvenanceHash, a precondition the brief does not place on mint(). The brief's "only while totalSupply is 0" guarantee is already enforced separately, so the gate is a spec deviation that makes mint liveness depend on an owner action. Merged from audit_flow and audit_economics.
• Low, vendored dependency drift. Eleven vendored Solidity files were reformatted after download. The project's own integrity script exits 1 on the delivered tree, and the dependency and security docs claim it passes. I downloaded the OpenZeppelin v5.1.0 archive and confirmed the lock file matches upstream, so the local copies drifted. Formatting only, no bytecode change.
• Info, freeze scope. freezeMetadata also locks setUnrevealedURI, which the brief scopes to setBaseURI. Merged from two specialists.
• Info, README owner literal. README states a wallet address as the resolved owner that no accepted input names. The manifest correctly passes $owner four times, so the risk did not materialise. Merged from two specialists.
• Info, team allowance not withheld. Public minting can consume all 10,000 before the owner reserve-mints, and reserveMint is also blocked while paused. Documented design consequence.

Verification run

• Full project suite: 93 tests pass.
• Specialist proof for the payable-transfer finding: fails for the stated reason.
• My scratch test reproducing the provenance gate, freeze lock, reserve-while-paused and fee conservation: all assertions hold.
• Dependency check: exits 1 at IERC2981.sol. ABI drift check: passes.

Coverage: all 20 listed entry points answered, plus three invariant rows for fee conservation, factory deployability and manifest schema. The manifest is schema-valid, names one contract with four $owner arguments matching the four constructor parameters, pairs with native ETH, and keeps notes under the limit.

The aderyn arbitrary-send lead was dropped: the recipients are immutable constructor roles behind a reentrancy guard. No specialist finding was dropped outright.

Implemented source, static export and documentation within scope.

• Build/typecheck passed.
• 60 browser tests and 16 design checks passed.
• Export: 696,325 bytes; verified complete bundle: 742,122 bytes.
• Design record: docs/DESIGN.md.
• No live transactions broadcast.

Workspace commit failed because .git/index.lock could not be created: Read-only file system. All deliverable files remain ready for submission.

Recorded in .imd-findings.json:

• Medium — bug: refreshed wallet balance leaves a false empty collection. After an incoming transfer, “Refresh state” shows “1 held” alongside “No cats.” Invalidate the cached ownership list when the balance changes.
• Low — bug: checking a cat owner requires an unrelated recipient. Entering token ID 1 and checking ownership fails unless a recipient is supplied. Validate the recipient only for reads that use it.

Both reproduce in Chromium and WebKit at 390 × 844. The findings include exact source snippets, changes and reproduction steps. No high-severity defect was substantiated.

The clean build and typecheck passed; every rebuilt export file matched the submission byte for byte. All 30 original interaction scenarios passed in each browser across completed runs and reruns; two intermittent failures passed on rerun. Live reads worked in both engines. No real transaction was broadcast. Implementation files remain unchanged.

The visual idea is a paper-colored mint desk, carried by large collection typography and one rust-colored mint action.
