The review is complete. Findings are in .imd-findings.json at the repository root, and the tree is otherwise unchanged.

Verdict: the game contracts are sound. No loss-of-funds, wrong-payee, accounting, reentrancy, access-control or rounding defect reproduced, and none of the launch-forbidden patterns is present. Two medium findings block the launch as committed, both outside the game logic.

Contracts read in full: DrandBeacon, IdentityMachine, Parts, Shapes, art/Catalog, MachineViews, EthMinter, plus launch.json, script/Deploy.s.sol, the test harness, mocks, dev pool and the security suite. The bls-solidity library was read at the points DrandBeacon uses it. The floor's OwnerChecks.sol is not in the tree and could not be read. Nothing else was out of reach.

Findings:

• Medium, src/EthMinter.sol:47. The constructor requires code at the PoolManager and Quoter addresses and calls the quoter. The launch rehearsal deploys on an empty chain, so the fourth manifest contract reverts BadPool and parks the launch. A proof test is attached. The values themselves are right: on live Robinhood Chain the quoter reports that PoolManager, the ETH/IMD pool quotes, and the repository's own fork test passed against the live pool during this review.
• Medium, test/Deploy.t.sol:61. The suite does not pass as committed. One test reads a generated file under art/out that is neither committed nor ignored, so it fails on a fresh checkout. All other tests passed, with the three fork tests skipped.
• Info, src/IdentityMachine.sol:361. Seat 65535 can never claim an Agent Core because the seat-plus-one field overflows. The committed snapshot holds seats 0 to 1999, so no holder is affected by this launch.
• Info, src/IdentityMachine.sol:309. The live IMD token has an owner with a blocklist that can freeze the machine, the burn address or any player. That is a dependency to record, not a defect in these contracts.

Also checked: manifest schema, names, argument counts and order, and $owner as the dev payout; runtime sizes under the EIP-170 limit; no DELEGATECALL, CALLCODE or SELFDESTRUCT in any runtime; no owner, pause, freeze, proxy or post-deployment setup; drand signature canonicality and round arithmetic; the plug-pay, shared-income, prize, reserve and referral accounting; v4 swap delta decoding, settlement and refund paths.

Next for the adapter: move the PoolManager and Quoter checks in EthMinter out of the constructor to first use, and either commit art/out/templates.json or make that test generate or skip its fixture.

Implemented the launch fixes: deferred pool validation, restored the art fixture, and fixed seat overflow. Manifest arguments and compiler settings remain unchanged.

Validation: forge build passed; seeded forge test passed with 231 passed, 0 failed, 3 skipped. Two targeted Robinhood fork tests also passed.

Changes and the external IMD blocklist risk are documented in ADAPTATION.md.

I found no economic defects I could reproduce. .imd-findings.json has an empty findings list and a coverage record of 31 rows: all 29 entry points, each marked holds with a one-line reason, plus two invariant rows. I changed no files besides that one, which git ignores.

What I covered (the Economic Security, Invariant and Flow Gap guides, after the Senior Auditor's Mindset):

• Where each mint's money goes. The shares add up exactly to the price paid: 50% plug-pay, 26% (or 23% with a referral) shared income, 15% pot plus a matching amount from the reserve, 5% reserve, 2% burn, 2% developer. The shared slice takes the rounding remainder, so nothing is created or lost.
• Paying out. claim rounds each payout down and records what was paid before it moves the rest, so it never pays out more than it took in. Repeating an id pays nothing extra. The prize places add up to exactly 10,000 basis points. Pots of finished rounds can no longer be paid out, and the next round's pot can't receive money early.
• Prices. quote and price use the same mint count as _mint, including after the clock runs out, when the next mint ends the round and the price restarts.
• Randomness. Each mint is revealed by a drand round at least 9 seconds after it. The signature that produces the randomness is fixed, so nobody can retry for a better roll.
• EthMinter. The swap buys exactly the IMD needed, spends at most msg.value, refunds the rest and leaves nothing approved afterwards. The callback can only be entered once and only by the PoolManager.
• Live checks on Robinhood Chain. The quoter belongs to the listed PoolManager. The ETH/IMD pool (fee 10000, spacing 100, no hooks) is set up with liquidity, at about 0.00228 ETH per IMD. The IMD token is a cross-chain token with a blocklist and no transfer fee, so the exact-amount bookkeeping is right.

What I left out:

• Some things I rejected as intended design or already known:
  • self-referral as a 3% rebate, which the code comments allow;
  • plugging new parts into your own parts to recover plug-pay;
  • holding cheap early-round parts to compete for the last-ten prize;
  • mints that are never revealed, which an existing test accepts;
  • the IMD owner's blocklist, already recorded as an outside dependency in ADAPTATION.md.
• Static-analysis leads. The flagged weak randomness, divide-before-multiply, strict-equality and reentrancy lines all came to nothing once traced.
• Not checked in depth. The wiring and geometry rules in Shapes and Catalog, beyond how the tier and shape rolls are chosen, and MachineViews beyond how its earnings views compare with claim. Both are outside the economics area.
• DevEthPool and DevIMD are local test stand-ins that are not deployed; their rows say so.

No finding needed a proof, so I wrote and ran no test files. A clean result here doesn't prove the code has no defects.

The review is complete. The findings file is written and valid, and no tracked file was changed.

Outcome. Within the Access Control, Asymmetry and Trust Gap lenses I found no permission bypass, no inconsistent guard, and no asymmetric value path in the four launched contracts. The build and all 231 non-fork tests pass. The findings file holds two info-level items and 32 coverage rows, one for each of the 29 listed entry points plus three invariants.

What I checked

• Every state-changing entry point of IdentityMachine, Parts, DrandBeacon and EthMinter: the caller each assumes, the guard that enforces it, and the storage it writes. No function takes an owner from msg.sender or tx.origin, Parts is bound to the machine in the constructor, and EthMinter holds only immutables.
• Paired surfaces: the four mint variants share one fee split; mint versus Agent Core claim; reveal inside and outside build; claim, referral claim and dev payout all zero balances before transfer; round end by endRound and by the next mint run the same code.
• Trust gaps: the plug-pay recipient is chosen by the payer and self-referral is allowed, but both are documented design. The callback in EthMinter is reachable only from the immutable PoolManager while a nonReentrant mint is in flight.
• The manifest: argument counts and order match the three constructors, $owner fills the dev payout slot, and on live Robinhood Chain the IMD token, PoolManager and Quoter have code, the quoter reports that PoolManager, and the ETH/IMD pool with fee 10000 and spacing 100 is initialized with liquidity.

Findings reported

1. Info, launch.json notes. The notes say EthMinter's constructor validates the PoolManager and Quoter. The accepted adaptation moved those checks to first use, so a wrong pool address would deploy fine and only fail at the first checkout. A scratch test under test/scratch confirms it. The live arguments are correct, so only the note needs rewording.
2. Info, trust assumption. The IMD token's owner, a single key, keeps a blocklist and can freeze every mint, claim and payout by blocking the machine or the burn address. The author already records this in ADAPTATION.md and the fork test. It is listed so the external privileged actor is in the review record.

Not covered. Randomness timing is outside my area and I did not substantiate it: the mint's drand round sits only nine seconds after the block timestamp, so a chain whose timestamps lag wall clock by that much would let a minter see the signature first. I could not reproduce that locally, so it stays a lead for the randomness specialist, not a finding.

The review is complete. The findings file is valid JSON with an empty findings list and 33 coverage rows, the scratch directory is removed, and the working tree is clean.

Outcome: no substantiated defect in the Math Precision, Boundary or Numerical Gap area. Every formula I traced holds at its edges, and four scratch probes confirmed the seams empirically before I deleted them.

What I checked in depth

• Mint split arithmetic. The six floored slices sum to at most 77% of the batch total, so the shared remainder never underflows. Plug-pay fits uint112 even at uint32 mint counts, and the drand round fits uint48.
• Reward accumulator. Claims keep the remainder in debt, so repeated micro-claims pay the same as one claim. With 1-wei sponsors over weights 1, 2 and 5 and a three-mint batch, the machine held exactly its obligations plus 1 wei of dust.
• Plug split and prize table. Per-link dust goes to the pot, the ten-place table sums to exactly 10,000 bps, the eleventh place reads zero, and the 70% floor's dust carries to the next pot.
• Quote parity. The machine's quote and the ETH checkout's total match the IMD actually pulled, including at the exact clock expiry where a new round opens at the base price.
• ETH checkout boundaries. Zero, short and excess msg.value paths, the int128 cap, the v4 delta lane decoding, the exact-output partial-fill check and the refund all behave as intended. The live quoter on Robinhood Chain answered normally for the manifest's fee and spacing, and quoter.poolManager() matches the PoolManager address.
• External token. IMD is a plain 18-decimal, non-proxy ERC-20, so the 0.10 IMD base price is correct. Its owner-held blocklist is already recorded as a trust assumption in the tree.
• Geometry limits. Footprint coordinates use checked int32 math, the bound checks allow the edge cell and require room for the next one, and the open-socket counter cannot underflow.

Noted but not reported as defects

• The 9-second sequencer-lag limit on drand reveal timing is a documented, accepted assumption with its own tests.
• DevEthPool locks ETH with no withdraw, but it is chain-id-gated to local Anvil and absent from the manifest.
• Each shared distribution strands fewer than totalWeight wei. That is dust with no compounding.

What I could not reach: nothing in my area was left unreached. The live end-to-end drand fork test was not run, and the dev harness contracts were covered only to the extent of confirming they cannot deploy on the target chain.

The deliverable is complete and verified. No further work remains, so nothing new to request.

I wrote launch.json as the single changed file, deploying the four accepted contracts in dependency order on Robinhood Chain:

• DrandBeacon with no arguments.
• IdentityMachine with the IMD token address, the beacon reference, $owner as the dev payout, the seat Merkle root, 0.10 IMD base price, and 172800 seconds delay.
• MachineViews with the machine reference.
• EthMinter with the machine reference, the PoolManager and Quoter addresses, fee 10000, tick spacing 100.

Every value was cross-checked against the accepted sources: the constants in script/Deploy.s.sol, the seat root in app/public/seats.json (Ethereum block 26132002), and the constructor parameter lists and declaration order in src/. The committed Deploy test that asserts the manifest equals the deploy script's constants passes unchanged, so the manifest describes exactly the accepted implementation.

The one repair was in the notes text: it claimed EthMinter's constructor checks the pool contracts and the quoter-to-PoolManager relationship, which describes the old timing before the accepted fix. The constructor now checks only that the machine has code plus fee and tick spacing, while the pool checks run on first use. I corrected that sentence, clarified that the launch deploys no new token, pool or distributor, and named the IMD token argument. No constructor argument or contract entry was altered.

Verification results:

• forge build passes.
• forge test with the pinned seed passes: 231 passed, 0 failed, 3 skipped, including the one-transaction CREATE2 rehearsal on an empty chain in test/LaunchDeployment.t.sol.
• A local schema check confirms only kind/contracts/notes, unique names within 32 characters, one entry per constructor parameter, backward-only $contract: references, static ABI words elsewhere, and notes under the 4000-character limit.
• Git shows exactly one modified file, launch.json; my scratch checks live under test/scratch and are excluded from the tree.

The review is complete and .imd-findings.json holds the result. The working tree is otherwise unchanged (the scratch test was removed, and out/ and cache/ are ignored).

Outcome: no critical, high or medium defect in the control flow. The project builds, all four launch contracts are under the EIP-170 size limit, and the committed suite passes with the fork tests excluded:

Suite scope	Result
forge test excluding test/Fork.t.sol	231 passed, 0 failed, 1 skipped

Findings written (3):

1. Low, src/IdentityMachine.sol:294. The mint commits to drand round roundAt(block.timestamp) + 3, a 9-second margin. On an Arbitrum Orbit chain the sequencer may stamp blocks behind real time, and any lag of 10 seconds or more makes the chosen round already public, so a minter can compute the part off-chain and mint only on a favourable roll. A scratch test confirmed the mechanics: with the randomness already set, mint and reveal succeed in the same block and the tier matches the pre-computed one. This is an unstated trust assumption on the sequencer clock rather than state corruption.
2. Info, launch.json:36. The notes still say EthMinter's constructor checks the PoolManager and Quoter. Since the accepted adaptation those checks run on first use. Schema, argument counts, order, $owner placement and notes length are all valid.
3. Info, src/IdentityMachine.sol:649. The per-weight rounding remainder in _distribute is never claimable but is added to totalPaid. Confirmed with a scratch test: three parts placed, sponsor(1) raises totalPaid by one wei that no part can claim.

Coverage: all 30 listed entry points have a row, plus two invariant rows and one for the read-only views. The eight DevEthPool and DevIMD entries are local-only mocks that are not in the manifest. I traced the full mint, reveal, build, place, claim, round-end and ETH checkout paths, the Uniswap v4 struct layouts and native-settle semantics, the Parts ledger, the BLS beacon's canonical-encoding uniqueness, and the Shapes and Catalog geometry tables. Not done: an on-chain check of the IMD, PoolManager and Quoter addresses on Robinhood Chain, and the fork test suite.

Added offline launch tests covering manifest deployment, failure rollback, real drand proofs, and three custody invariants.

forge build passed. Full tests with the supplied seed: 237 passed, 0 failed, 3 fork-only tests skipped.

Changes are confined to test/.

Review complete. The findings file is written and validated: all three snippets match the tree at their lines, and the coverage record answers all 29 entry points plus the manifest and the IMD conservation invariant.

Outcome of the specialist findings

• Kept, low: the 9-second drand margin (audit_flow). I reproduced it on this tree with a scratch test: when the beacon already holds the randomness for roundAt(block.timestamp) + 3, a mint and its reveal succeed in the same block and the revealed design equals the one computed before paying. Nothing at mint time checks that the committed round is still unpublished, so a sequencer clock 10 s or more behind real time lets a minter pick outcomes. No funds move wrongly, so low.
• Kept, info: _distribute rounding dust counted in totalPaid (audit_flow). Reproduced: three weight-1 caps placed, sponsor(1) raises totalPaid and the machine balance by 1 wei while the parts' claimable sum is unchanged.
• Kept, info, as a trust assumption: the external IMD token's owner blocklist can halt mints, claims and payouts (audit_permissions). Not a defect in this code; the token is fixed by the brief. Recorded with the existing fork test as its reproduction.
• Dropped: both specialists' "launch.json notes still claim constructor-time pool validation" findings. The notes in this tree already say the pool contracts and quoter relationship are checked on first use, so the mismatch does not reproduce.

My own pass found nothing further. I checked the leads the tools raised and the areas most likely to hide a loss of funds: the BLS signature path (the library requires exactly 64 bytes and the pairing precompile rejects coordinates above the field prime, so the beacon's randomness is not malleable), the Uniswap v4 delta decoding and settle/take flow in EthMinter, the mint split and plug-pay conservation, placement geometry and the growth-exit check, round settlement, and the manifest's argument order, owner placement and constructor dependencies. The project builds, and the unit suites pass with 226 tests. Invariant and fork suites were not rerun within the time budget. The scratch test directory was removed, so the working tree is clean.
