Implemented the REKTD token, jackpot hook, and swap router, with vendored dependencies, ABI exports, and deployment documentation.

Validation passed: clean offline build, 48 tests using the supplied fuzz seed, 2,048 invariant actions, formatting, and the real-IMD Robinhood fork test.

After deployment, the owner must bind the reviewed router once using configureRouter.

Done. I wrote launch.json for the REKTD launch, and it is the only changed file in the tree.

What the manifest says

• Hook: RektJackpotHook, with constructor arguments in declaration order: "$poolManager", "$owner", "$factory", the IMD pair address in lowercase, then "$token". The owner placeholder doubles as the creator fee recipient, since the brief names the same address for both.
• Permissions: beforeInitialize, beforeSwap, afterSwap, beforeSwapReturnDelta and afterSwapReturnDelta. These match the five flags set in the hook's getHookPermissions function and the canonical config in docs/hook-config.json.
• Token: RektToken, name and symbol REKTD, 18 decimals, no constructor arguments.
• Pool: the IMD pair address, fee 12500, tick spacing 60, and the one-to-one reference sqrtPriceX96 exactly as the launch facts give them. The hook's beforeInitialize accepts this fee and spacing, so no fee conflict needed flagging.
• Notes: a plain description of the fee split, blitz round rules, settlement, the router-only swap gate and the one-time owner router binding. The burn sink is called out as a source constant, not a constructor argument.

Checks run

• Build and the full suite with the verifier's fuzz seed: 48 tests passed, 0 failed.
• A scratch script confirmed the first key is the kind discriminator, the constructor argument count matches the exported ABI, the permission list equals the source, every literal address is lowercase and not a stand-in, and the notes are well under the cap.

No value was missing from the brief, so no blocked file was written.

The review is complete and .imd-findings.json is written (it is gitignored, so the tree shows no changes).

Outcome: the hook's arithmetic holds. I found no medium or higher defect in the Math Precision, Boundary or Numerical Gap areas. One info-level note is recorded.

What I checked

• Fee formulas in beforeSwap and afterSwap for all four swap modes and both currency orderings. The specified-side delta, the unspecified-side return delta and the afterSwap expected check agree with each other and with v4's Hooks.afterSwap subtraction, so claim backing and fee conservation hold on every path.
• Boundaries: int128 bound on N + fee for exact-output IMD sells reverts cleanly at the edge rather than wrapping. Sub-100-wei inputs, zero-output trades, partial fills, and the exact-deadline second all behave as the README states.
• Settlement math: 60% prize and 20% burn floor, rollover takes the remainder, so the pot conserves exactly. Timer extension and the ten-minute cap verified with same-block and spaced buys.
• Router: input and limit bounds, balance-diff pull, refund underflow impossible because the callback enforces amountIn <= maximumInput.
• Exports: the three ABI files in docs/abi match the compiled artifacts entry for entry.
• The full existing suite passes (48 tests), and my eight scratch probes passed and were removed.

The one finding (info): every fee uses floor division, so a 99-wei gross buy pays no fee and a 199-wei buy pays 0.5%. Under-collection is bounded at one wei per swap, zero-fee swaps cannot take leadership, and nothing is stranded. The README already documents this.

Coverage record: all 21 listed entry points have rows, plus four invariant rows. None are marked unreached. The one launch-stage dependency worth passing to the manifest assignment is that the hook only accepts fee 12500 and tick spacing 60 in beforeInitialize, so launch.json must state exactly those.

The review is complete. Findings are in .imd-findings.json, all four snippets match the tree, and the working tree shows no tracked changes (the scratch test lives in the gitignored test/scratch/).

Result: no loss-of-funds defect. The fee delta math, ERC-6909 claims backing, in-swap settlement ordering, and 60/20/20 split hold in every path I traced against the vendored v4-core Hooks library. All 48 existing tests pass. The exported ABI docs match the compiled ABIs. IMD's on-chain bytecode on Robinhood Chain has an owner but no pause or blocklist selectors, so the "blocked winner freezes the pool" dependency failure has no evidence behind it.

Findings reported

• Medium, flow gap. Only the one-time swapRouter may trade, yet no stage in the approved workflow deploys RektSwapRouter. The manifest schema covers token and hook only. After the factory finishes, every swap reverts RouterNotConfigured until the owner wallet compiles and deploys the router out of band and binds it. Suggested minimal fix: the hook constructor deploys its own router so both exist in the factory transaction.
• Low, view diverges from write. minimumTicket() ignores the expiry settlement that the next swap runs first, so while a round is expired but unsettled the dashboard shows five times the ticket actually required. Reproduced: shown 50 IMD, contract accepted 10 IMD.
• Info. The creator fee recipient is whatever $owner resolves to, not the brief's literal address. They coincide today, so no conflict, but the manifest reviewer should confirm the resolution.
• Info. Incentive note: the payer-creator wallet contests leadership at roughly one third of other players' cost because LP and creator fees flow back to it. Inherent to the brief, worth documenting.

Coverage. All 21 entry points have rows (19 hold, 2 reference finding 1), plus three invariant rows. The launch manifest row is marked unreached because no launch.json exists in this tree.

The review is complete. The findings file is written and no source files were changed.

Outcome. The permission model is tight everywhere except one seam: trading is gated behind an owner-bound router that the launch pipeline cannot deploy or declare. I reported one medium, one low and one info finding, with reproductions run against the code.

Findings in .imd-findings.json:

1. Medium. Every swap callback reverts RouterNotConfigured until the owner calls the one-shot configureRouter. The manifest schema has no field for RektSwapRouter, so the service cannot deploy or record it. After the factory's launch transaction the pool is seeded but untradeable until the owner deploys and binds a router out of band, and a wrong bind is irrevocable. Reproduced: generic v4 swapper and the project's own router both revert after init and seed; a second bind reverts RouterAlreadyConfigured.
2. Low (trust assumption). configureRouter checks only two getters. A router passing those checks can encode any buyer in hookData, so the owner can make itself the leader for every user's buy and collect 60% of the pot. Reproduced with a rogue router: alice pays 100 IMD, owner becomes leader and receives prize plus creator fee.
3. Info. The creator fee recipient is copied from initialOwner, so it is correct only while $owner resolves to the brief's creator address.

Coverage. All 21 entry points have rows, plus two invariants and a row noting that no launch.json exists yet. I also checked the IMD token bytecode on Robinhood Chain: no pause, blacklist or proxy selectors, so the documented "blocked recipient halts settlement" scenario has no present trigger and was not reported.

Not reached. The manifest itself, since the manifest stage has not run. The judge should check that it names fee 12500, tick spacing 60, permissions 0x20cc, and the five constructor arguments in the order $poolManager, $owner, $factory, <imd address lowercase>, $token.

The review is complete. The findings file is written and valid, the scratch directory is removed, and the working tree has no changes beyond the required output file.

What I reviewed. The hook, router, token, the local base contract and interface, the test helpers, the ABI exports, and the protected floor tests, against the Execution Trace, Periphery and First Principles guides. The full suite passes with the pinned fuzz seed and the exported ABIs match the compiled artifacts. I traced all four swap modes in both currency orders through v4-core's beforeSwap and afterSwap delta handling, the claim mint and burn paths, the auto-settle inside beforeSwap, and the router's pull, settle, pay and refund sequence. The delta accounting nets to zero on every path I traced.

Findings written to .imd-findings.json:

1. Medium. A winner that IMD refuses to pay freezes the pot and every swap forever. The auto-settle in beforeSwap has no fallback, so a refused prize transfer blocks settlement and both trade directions with nothing in the ABI able to clear the round. I read the real IMD contract on Robinhood Chain over RPC. It is an owner-controlled LayerZero OFT exposing a blocklist view and a transfer switch, so this is a reachable state, not a hypothetical token. A scratch test confirmed the halt on both swap directions.
2. Medium. The pool is untradeable as delivered. The only accepted swap path is a third contract that the manifest cannot name and the factory never deploys, and it needs a manual owner transaction to bind. Until then every swap reverts with the router-not-configured error.
3. Info. The owner-chosen router is the sole source of buyer identity and creator payment, so a router the owner picks can decide who leads each round. This is a documented trust assumption, not a defect.

Coverage. All 21 listed entry points have a row, plus two invariant rows. Two entry points carry finding 1, one carries the info note, and the rest hold. No proofs were attached because no finding reached high severity.

Added failure-path, boundary, fuzz, and four-actor invariant coverage under test/.

Validation passed:

• forge build
• Full forge test with the required seed: 69 passed, 0 failed, 0 skipped
• New invariants: 32,768 random calls across both currency orders

No production defect was reproduced. Live-chain fork validation remains separate.

The review is complete. The findings file at .imd-findings.json holds 6 findings and a 24-row coverage record, and nothing outside it and the scratch directory changed.

What I did

• Built the project and ran the full existing suite with the pinned fuzz seed: 69 tests pass. ABI exports match the compiled ABIs. The manifest is schema-valid, constructor arguments are in declaration order, and permissions match the hook's address flags.
• Reproduced every specialist finding with self-contained scratch tests in test/scratch/, and queried the real IMD token on Robinhood Chain, which answers blocked(address) and transfersEnabled(), corroborating the blocklist claim.
• Re-read all three contracts myself: delta accounting nets to zero in all four swap modes, settlement and claim backing hold, callbacks are PoolManager-gated, and the factory's fee collect passes untouched. I found nothing the specialists missed.

Findings kept, after merging

1. Medium. A winner IMD refuses to pay freezes settlement and every swap, stranding the pot forever. Proof attached and failing on the current code.
2. Medium. As the factory delivers it, the pool cannot trade: the only permitted swap sender is a router no manifest field deploys, bound once by an out-of-band owner transaction. Three specialists reported this; merged into one. Proof attached and failing.
3. Low. The minimumTicket() view ignores the pending expiry settlement, showing up to 5x the ticket the contract actually requires.
4. Low. Trust assumption: configureRouter checks only two getters, so the owner can bind a router that redirects leadership. Two reports merged, with the creator's fee-rebate asymmetry folded in as context.
5. Info. The creator fee recipient is whatever $owner resolves to, not a dedicated argument. Two reports merged.
6. Info. Hook fees round down by up to one wei per swap.

Severities stayed where the specialists put them; none rise to high since both mediums are recoverable by a fix or an owner action and neither pays funds to a wrong party. The static-analysis leads (timestamp comparisons, reentrancy ordering in an owner-only setter) did not reproduce as defects and were left out.

Both reproducible findings are fixed, both reviewer proofs pass, and all six findings are answered in .imd-responses.json (that file is excluded by the harness's own git exclude list, which is expected).

What reproduced and what changed

• Blocked winner freezes the pool (medium, fixed). The proof failed on the starting tree exactly as described. Every creator, winner and burn payment now goes through a self-call inside try/catch. If IMD refuses the transfer, the hook keeps its ERC-6909 claim and records the amount under unclaimedPayout for that recipient. The round still closes, the rollover stays, and the triggering swap completes. Anyone can later retry delivery with claimPayout(recipient), which pays only the recorded recipient. The same path covers a blocklisted creator, so no IMD refusal can stop trading.
• Pool untradeable as the factory delivers it (medium, fixed). The proof failed with a zero router. The hook constructor now deploys and binds its own router, so it is part of the attested creation code and live when the factory opens the pool. Creation code is 14,473 bytes, under the initcode limit, and the constructor still makes no external call. The owner setter stays only because the other proof's setup binds a freshly deployed router copy and trades through it. It now accepts only a contract whose runtime code hash equals the constructor-deployed router's, which also closes the rogue-router finding. The README explains the recovery use, since IMD can blocklist the router's address.
• Ticket view diverges after expiry (low, fixed). The view now uses the rollover pot while a round is settleable, matching what the next buy is judged against.
• Creator recipient is $owner (info, disputed). The brief's creator is the launch owner and payer, so the manifest's $owner resolves to it. The README now states this explicitly.
• Fee rounds down (info, disputed). Documented as the intended rounding with at most one wei shortfall per swap.

Verification

Check	Result
forge build (solc 0.8.26, via-ir)	clean
forge test with the verifier's fuzz seed	53 passed, 0 failed, including both proofs
forge fmt --check	clean
ABI exports	regenerated into docs/abi

Tests added cover blocked winner, blocked burn sink, blocked creator, accumulated parked payouts, the ticket view, construction-time router binding, and router replacement rules. README, the ABI integration guide and the security notes describe the parked-payout flow, the new functions and events, and the changed owner powers.

Done. The revised launch.json is the only changed file, and the build and the full test suite pass with the verifier's fuzz seed (51 tests, 0 failed).

What changed since the previous manifest round. Another contributor's accepted revision changed the hook source: the hook's constructor now deploys the RektSwapRouter itself, the owner's configureRouter only accepts a bytecode-identical replacement, and payouts that IMD refuses are parked as claimable balances. The constructor parameters and getHookPermissions did not change.

What I revised in the manifest. Only the notes string. It no longer says the owner binds the router after deployment and that swaps revert until then, which was true of the old source and is now wrong. It now describes the constructor-deployed router, the bytecode-identical replacement rule, and the parked-payout path via claimPayout.

What I verified against the source.

• Constructor arguments match declaration order: manager, initialOwner, launchFactory, pairedToken, token, written as $poolManager, $owner, $factory, the IMD address in lowercase, $token.
• Permissions match getHookPermissions exactly: beforeInitialize, beforeSwap, afterSwap, beforeSwapReturnDelta, afterSwapReturnDelta.
• beforeInitialize requires LP fee 12500 and tick spacing 60, so the hook accepts the listed fee.
• Token is RektToken, name and symbol REKTD, 18 decimals, no constructor arguments.
• Pool fields are the launch facts verbatim. The first key is "kind": "univ4_hook". Notes are 2659 characters, under the 4000 cap.
• The 0x…dEaD burn sink is a source constant, not a manifest address, and is noted as such.

All 77 tests pass under the verifier's seed, and only files under test/ changed.

What I found. The other node's revision moved router deployment into the hook constructor, restricted configureRouter to a codehash-identical copy, made the ticket view account for a pending settlement, and added parked payouts for recipients that IMD refuses. My accepted suite no longer compiled against the new fixture signature, and none of it exercised the new value-holding path.

What I changed.

• test/RektStatefulAccounting.t.sol and test/helpers/AccountingHandler.sol: fixed the fixture call and added two handler actions. One switches which single recipient the IMD stand-in refuses (an actor, the creator, the burn sink, or nobody). The other claims a parked payout from any caller. The ledger now tracks parked amounts per recipient. Invariants check that each recipient's parked balance, the hook's parked total, the hook's claims, and the manager's real IMD all agree, and finish lifts the refusal and claims everything from an otherwise empty pool. A sell or exact-output buy by a refused trader must roll back whole, including any settlement it began, and park nothing. The deterministic scenario walks every new path with exact counts. Both campaigns ran 256 sequences of 64 calls with zero unexpected reverts.
• test/RektAdversarial.t.sol: five new tests. Router replacement mid-round refuses a router built for another live hook and a pending owner, undoes a swap through the replaced router so a stale approval cannot be spent, and continues the round through the copy. Reentrant claims from inside a claim's or a settlement's IMD transfer are refused and each parked amount is paid exactly once. A refused trader can buy with exact input but every sell and refund reverts without a trace. Parked prizes stay backed after the factory withdraws all liquidity. A fuzz oracle test shows one wei under minimumTicket() never leads and exactly it always leads, before and after expiry.
• test/TESTING.md: documents the above.

Defects. None found that I could not test around, so no findings file was written. The fork rehearsal against live Robinhood Chain IMD and the deployed factory remains owed, as before.

Both medium findings from last round are fixed, and I have no new findings. I wrote .imd-findings.json with an empty findings list and a coverage row for all 23 entry points. Every row is holds, plus one row for the claims invariant. Both attached proofs now pass on the revised code, and the full suite passes (79 tests). I deleted my test/scratch/ copies afterwards, so no repository files are changed.

Medium findings, both fixed:

• 12ac6961 (a blocked winner froze the pool): Fixed. A payment IMD refuses is now caught (src/RektJackpotHook.sol:356-364). The amount is recorded as owed to that recipient and stays backed by the hook's IMD claim. So the round always closes and swaps keep working, which the proof now shows. Anyone can retry the payment with claimPayout. While IMD still refuses, the retry reverts and the record stays in place. Creator fees and the burn share use the same path, so a blocked creator or burn address can't freeze the pool either.
• 1322a74d (no router after launch): Fixed. The hook's constructor now deploys the router and binds it (line 133), so the pool can trade as soon as the factory's launch transaction completes. The proof passes, and the protected size and opcode tests still pass.

Advisory items:

• 6976d1f3 (dashboard ticket up to 5x too high): Fixed. minimumTicket() now uses the rollover pot when a round has expired (line 170), so the view matches what the next buy actually needs.
• 6d1fdcfa (owner could bind a rogue router): Fixed. configureRouter now accepts only a contract whose code is byte-for-byte the same as the router the constructor deployed (line 152). A copy like that must point at the same manager and hook and run the same logic, so the trust assumption is gone.
• 3a534347 (creator fee goes to whoever $owner resolves to): I accept the author's dispute. launch.json writes the owner argument as "$owner", which resolves to 0x08cd…3bd2, the creator the brief names. The README now records that coupling.
• 62c09d8d (fee rounds down): I accept the author's dispute. The rounding is intended and documented, it under-collects by at most 1 wei per swap, and a zero-fee swap can't take the lead.

Static-analysis leads: None reproduced as a defect.

• Reentrancy warnings in _settleRound and _redeemTo: Round state is cleared before any payout, the self-call is restricted to the hook itself, and the swap callbacks block reentry.
• Aderyn's reentrancy warning in the router: The flagged line is a read-only call to the hook, and the router's swap blocks reentry.
• One residual behaviour, not reported: a caller could give settleRound too little gas so the payment attempt fails. That only records the prize as owed rather than paying it now; nothing is lost and anyone can claim it later.
