The review is complete. The findings file holds one informational item and no defects above the accepted list. The working tree is unchanged apart from the findings file, which git ignores.

Result

No critical, high, medium or low defect reproduces in the eight job B contracts beyond what the requester already accepted. The launch inputs check out:

• All eight creation-code hashes computed from a fresh build with the unchanged foundry.toml match both the task's expected hashes and the pinned ModuleCode table for roles 6 through 13.
• Every runtime is under the EIP-170 limit. Each constructor takes one address and makes no external call, so the empty-chain rehearsal passes.
• On Robinhood Chain the recorded GameRegistry has code, reports the recorded token, Params and V4Market, holds the 200,000,000 endowment figure, has roles 0 through 5 registered and roles 6 through 13 empty. No prefill by a copy has happened. The Desk reports the registry as bound. The hook's fee router is still unbound, as the wiring plan expects.
• Existing suites covering Season, Civic, Billboards, bounties, grid and economy pass on this tree.

One informational finding is recorded in the file. In GridOperator, when the positive-streak rule replaces a submitted negative plan with Green or Cheap, the event keeps the plan's severity. A plan at the 3000 floor therefore produces a Green event worth 300 bps instead of the 1000 bps the fallback path gives. No funds are at risk and the swarm cannot profit from it. The file states the exact epoch state that triggers it.

Contracts read in full: FeeRouter, GridOperator, Season, FarmEngine, Economy, Enhancement, Civic, Billboards, GameRegistry, GameModule, ModuleCode, Params, RewardPool, ChainClock, EconomyMath, Errors, Robinhood, and the IGame and IGameRegistry interfaces.

Read only in the slices the L4 modules call: FarmCore, FarmRewards, FarmItems, PackSale and V4Market. The parts I traced are the equip, scrap, enhancement, settlement, season-completion, sell-proceeds and purchase-unit paths.

Not reached: SwarmDesk, StarterClaim, EndowmentEscrow, MarketFactory, StandardMarket, StandardAdapter, the oracle library and the remaining V4Market hook logic. These are L1 to L3 pinned code outside job B.

Leads checked and rejected: an enhancement dodge by equipping or scrapping a pending item is blocked in FarmCore. A surge-target mismatch for destroyed items is unreachable because FarmCore removes destroyed ids in the same settlement call. Double counting of sale proceeds in the fee router cannot happen because the hook pays from its own address while the selling flag is set. Season pot shares, district claim division, rollover timing and lottery draws all conserve the pot. Civic war and collapse accounting conserves escrow. Heartbeat balance can never exceed its cap, so the sell path never underflows.

Work is complete and verified. Recap:

Outcome. The L4 (job B) launch needs no source change, and none was made. The eight contracts built from the unchanged foundry.toml reproduce the brief's creation hashes exactly, in the listed order, each taking the single recorded L3 GameRegistry word.

What I verified against the unchanged source

• Every creation hash (FeeRouter, GridOperator, Season, FarmEngine, Economy, Enhancement, Civic, Billboards) matches the brief and the recorded v3.18 artifacts, with no link references.
• Each constructor is nonpayable, takes one address, makes no external call and does not require code at that address, so it runs on the protected probe's empty chain. A scratch mirror of the probe deployed all eight by CREATE2 on an empty chain, confirmed every runtime is under the EIP-170 limit, and found no DELEGATECALL, CALLCODE or SELFDESTRUCT.
• No L4 contract has an owner, admin or privileged setter, so nothing can fall to the factory or IMD's wallet.
• The project's own module and swarm pin checks pass under both toolchains.

Audit finding 0d49094e (info). It reproduces: with Outage plans at the 3000 floor, the positive-streak override turns epochs 19 and 20 into Green at severity 3000 (300 bps bonus) while the unplanned epoch 18 resolves Green at 10000 (1000 bps). It is not fixed, because GridOperator is pinned in the bound registry and the brief forbids source edits. It is accepted and recorded, and a second test shows the keeper rule: a plan submitted at 10000 for a forced-positive epoch resolves at full strength.

Files changed

• test/AuditL4V318.t.sol: two new tests reproducing the finding and the keeper rule.
• docs/accepted-v318.md: new "Accepted at L4" section for the finding.
• ADAPTATION.md: the change list, the hash table, the launch-rule verification and the checks run.

Checks. forge build succeeds. The full suite with the verifier's fuzz seed passes with no failures (331 passed, 6 skipped fork tests that need a fork URL, as before). The new test file passes forge fmt --check. No file under src/, script/, launch/, vendor/ or the build configuration was touched, and launch.json was not written.

I've written launch.json for BLACKOUT L4 (job B) on Robinhood Chain (4663). It is the only file I changed. I can't give you the addresses, indices or launch number: they only exist once the launch is actually deployed.

The manifest: kind evm_contracts, eight contracts in the order you listed: FeeRouter, GridOperator, Season, FarmEngine, Economy, Enhancement, Civic, Billboards. Each one's single constructor argument is the L3 GameRegistry, 0x1b41fc9723df25eec7e91d947072dccc2483285f. None of these constructors takes an owner, so there is no $owner anywhere.

The notes field (1,746 of the 4,000 characters allowed) records:

• the L1/L2/L3 addresses and the registry binding
• the build settings
• each contract's creation hash
• what the keeper does after this launch
• GAME_CONFIG_HASH
• a summary of the accepted findings, including d873782c and b61f7912

Checks:

• Creation hashes: I built with the unchanged foundry.toml. The hash of each contract's compiled creation code, before the constructor argument is appended, matches the expected value in your brief for all eight.
• Empty-chain constructors: All eight constructors only reject a zero address and store the registry. They make no external calls, so they will also run on an empty chain.
• Tests: forge test with the verifier's fuzz seed passed 329 tests with 0 failures and 6 skipped, across 57 suites.

I haven't committed launch.json; it is currently an untracked file.

Review complete. The findings file is written and validated.

Outcome. The eight L4 contracts hold up well under the Math Precision, Boundary and Numerical Gap checklists. I found no fund-moving arithmetic defect. Two items are recorded in .imd-findings.json, both with concrete inputs, neither severe enough to need a proof file.

• Low, FarmEngine set cap clips paid overclock. The room cap at src/FarmEngine.sol:149 is applied to raw hash that already includes the per-item overclock bonus, so in a full-combo room every overclock level above 10 adds zero hash to both the committed allocation and settled output. Enhancement still sells those levels at 19 to 55 days of item yield each with a 65 to 90 percent burn chance. Reproduced in a scratch test against the Base harness: the allocation hash plateaus at 7,680,000 from level 10 onward.
• Info, Civic war score scale mix. The score at src/Civic.sol:187 adds chest points scaled to 10,000 per average daily yield to the raw district hash, which sits in the tens of millions. A district that funds 100 times average daily can still lose to an unfunded district with modest hash and forfeits its whole chest to the pool. The war feature is dormant at launch, so this is informational.

What I verified as holding. FeeRouter ETH and token splits conserve value exactly, the heartbeat balance can never exceed its fixed 1 ETH cap, and the sell split cannot underflow team tokens. Season pot shares sum to at most 100 percent, the district claim divisor is always at least one, the lottery tree walk is exact, and rollover can never target a finalized week. GridOperator stability stays within 5,000 to 15,000 with no zero divisor. Economy quotes use consistent WAD scaling, including the repair quote whose hours parameter is itself WAD-scaled. All downcasts are range-bound by prior checks.

Coverage. All 157 listed entry points have a row, plus four invariant rows. The 78 rows marked unreached are entry points outside the L4 math area that I did not review, in FarmCore, FarmRewards, PackSale, StarterClaim, SwarmDesk, the markets and the registry.

Not covered. Cross-module economic effects of the lazy settlement path in FarmRewards and FarmCore were only read where L4 consumes their outputs. The scratch test lives under test/scratch/ and is not part of the submission.

The review is complete and the findings file is in place. Nothing further depends on another result, so here is the recap.

Outcome. The eight L4 modules (FeeRouter, GridOperator, Season, FarmEngine, Economy, Enhancement, Civic, Billboards) hold on the Access Control, Trust Gap and Asymmetry checks. I found no permission bypass, no escalation path and no in-flight value a privileged write can redirect. One informational asymmetry is recorded.

What .imd-findings.json contains

• One finding, severity info. Season's recordSpend guard admits GridOperator as a caller, but the pinned GridOperator never calls it. The permission is dead code of the same class as accepted info 7. Reproduction: a call pranked from the registered module 7 succeeds and writes the week's spend, while no deployed transaction can originate it. No proof test, since it is not high or critical.
• Coverage for all 157 listed entry points plus two invariant rows. 138 hold, 1 is the finding, 20 are unreached.

What I traced and why it holds

• Every authority in the eight modules derives from registry.module(role) or the Params swarm wallet, which is the L1 SwarmDesk, so each swarm-only action reaches the chain only through an attested, stored answer. There are no owners, setters, delegatecalls or selfdestructs.
• Keeper paths that looked like the Trust Gap guide's access-times-economics seam (executeBuys, executePotBuys, executeSells) are floored against a 30-minute TWAP quote, not spot, and sells are capped by maxSellBatch, so a same-transaction sandwich cannot lower the floor.
• Enhancement outcomes cannot be dodged: FarmCore refuses to place or scrap an item with a pending attempt, and a lapsed attempt settles at its worst outcome, so the _apply holder check is unbreakable.
• Season claim shares (40/30/30) are computed under the same predicate that counts eligible payers at complete, and no spend can reach a week after it is completed, so shares sum to at most the pot.
• Civic war top-10 capping, Billboards escrow and refund mirroring, and Economy lock/unlock storage writes are symmetric.

Not reached. The V4Market hook internals, StandardMarket and StandardAdapter reference contracts, MarketFactory, and FarmRewards settlement internals. These are L2/L3 code outside the assigned area, and the rows say so.

No files other than .imd-findings.json were created or changed.

The review is complete and the findings file is in place. No files in the tree were changed.

Outcome: no reproducible defect found in the L4 job B control flow. The file .imd-findings.json holds an empty findings list and a 161-row coverage record (157 entry points plus 4 invariants).

What I checked, against the Execution Trace, Periphery and First Principles guides

• Launch and registration path. I rebuilt all eight L4 contracts with the unchanged foundry.toml and hashed their creation code. Every hash equals both the ModuleCode pin for roles 6–13 and the hash listed in the task, so GameRegistry.register with the registry as the sole constructor word will accept the recorded deployment. Constructors make no external calls, so the empty-chain rehearsal cannot park the launch.
• Cross-module execution traces. Sell and buy flows between FeeRouter and V4Market (the hook sends ETH itself while the router's selling flag is set, so receive() cannot double count), pot buys into Season, epoch close through GridOperator.resolveFor and shift, Civic and Billboards escrow into RewardPool.donate, Enhancement commit and resolve through FarmCore.prepareEnhancement, and Economy lock and unlock through FarmCore.syncFor.
• Wrong-state and interleaving cases. Season pot accounting: a week's pot is frozen before any claim because deposits and rollovers only credit the wall-clock current week, which can never be a finalizable week. The district share division is safe because the claim checks imply at least one eligible payer. Spend recorded after a week completes is impossible since the epoch clock lags the wall clock.
• Periphery. ChainClock's 256-block window matches ArbSys and blockhash bounds, EconomyMath and ItemMath bounds are enforced by callers, and GameModule's registry slot has no writer.
• Arithmetic. The repair quote divisor looked off by a factor of ten against its parameter name, but the test suite documents the intent as six hours per ten percent restored, so it is not a defect.
• Existing suites. Civic, Pot, SeasonAudit, AuditL4V318, FeesParams, Grid, Economy and KeeperProfit tests all pass on this tree.

Coverage boundaries

• Holds: all eight L4 contracts, plus the L3 modules they call (FarmCore, FarmRewards, FarmItems, PackSale, RewardPool, GameRegistry, Params) and the three V4Market functions the router uses.
• Unreached: the L1 and L2 contracts outside this area (SwarmDesk, EndowmentEscrow, MarketFactory, StarterClaim, StandardMarket, StandardAdapter and the V4Market hook callbacks). Nothing in the L4 area changes their behaviour.

Accepted items confirmed as stated. The 0d49094e forced-positive severity, the d873782c unlock resync skip, the rollover-before-finalize ordering and the 33-tie lock insertion all behave as the acceptance notes describe. I found nothing that contradicts an accepted line or that would block deploying the eight listed creation hashes.

Envelope confirmed: MAX_OUTPUT_BPS = 15000, and the worst stacked L4 case (Festival 1500 bps on top of a 1500 bps season boost plus a 1000 bps war boost) is 1.15 × 1.25 = 1.4375 < 1.5, so no honest settlement can trip the spent > allocation revert. The working tree is clean apart from the findings file and my scratch test.

Recap

Outcome. The review is written to .imd-findings.json: one low finding and a coverage record with 166 rows, one for each of the 157 verifier-listed entry points plus nine invariants and the manifest/constructor check. No critical, high or medium defect was found in the eight job B contracts under the Economic Security, Invariant and Flow Gap guides.

The one finding (low). FeeRouter.executeBuys accepts any amount down to 0.05 ETH and stamps lastBuy, which is the same five-minute cadence executePotBuys uses. The sells side was explicitly hardened against dust (amount is forced to the queued batch), the buys side was not. A dust caller who wins each slot caps reward and pot buys at 14.4 ETH per day and is reimbursed from the heartbeat for doing it. Delay only, no loss; reproduced in test/scratch/BuyCadence.t.sol. It cannot be fixed in source (pinned), so the mitigation is operational: the keeper submits its full batch exactly at lastBuy + 5 minutes.

Leads traced and closed, each with the guard that closes it:

• Sell-tax double count in executeSells: the hook holds tax until a separate flushFees call, so the balance delta sees only proceeds.
• Dodging a bad enhancement roll by equipping or scrapping: place and scrap refuse items with a pending attempt, and commit requires unequipped and not in the active snapshot.
• Keeper-call sandwiches: both market quotes are 30-minute TWAP, so the 1.5% bound cannot be moved within a block.
• Mixed ETH/token units in Season spend: PackSale passes the token cost, so every path is token wei.
• Season pot arithmetic: claims per week sum to at most 100%, the district divisor always counts the claimant, and rollover can only land in a week whose claims have not opened.
• Escrow conservation in FeeRouter, Season, Civic, Billboards and Economy all hold.

Documented as trust, not findings. startCollapse has no upper bound on the goal, so the swarm can force one global Outage epoch after feature 1 is enabled with 48 h notice. The war score's funding term is small against the district-hash term, so wars are largely decided at startWar; losers fund knowingly, no funds are taken.

Not reached. L1/L2/L3 contracts outside the job B set (SwarmDesk, EndowmentEscrow, StarterClaim, V4Market hook callbacks, StandardMarket/Adapter, MarketFactory) and a few FarmCore/PackSale paths not on any L4 flow are marked unreached in the coverage record.

Added 27 tests under test/l4, including five invariant suites, exact creation-hash checks, and failure-path coverage.

forge build and full forge test passed with the supplied seed: zero failures, six existing RPC-dependent skips.

Only test files changed; pinned sources and configuration remain unchanged.

The review is complete and .imd-findings.json holds the result. Git status is clean apart from the findings file and my scratch tests, which are ignored by the tree.

Outcome. No blocking defect. The launch as described can deploy: the creation-code hash of each of the eight L4 contracts built from this tree equals both the ModuleCode pin and the hash the task expects, runtime sizes are between 6,031 and 13,019 bytes, and every constructor only stores the registry address, so nothing reverts on an empty chain. The manifest lists the eight contracts in role order 6 through 13 at indices 0 through 7 with the recorded L3 registry as the single static word, which is exactly what GameRegistry.register will predict.

Findings kept, all reproduced in test/scratch/Review.t.sol and all on pinned code, so none require a source change:

• Low, FarmEngine line 149. The second cap on room output is computed on a base that already includes the overclock bonus, so once the swarm raises the enhancement cap past 10, levels 11 to 16 add zero hash while Enhancement still charges and can burn. Measured: allocationHash stays at 7,680,000 from level 10 to level 16 for a triple-core mythic room.
• Low, FeeRouter line 292. A 0.05 ETH buy stamps the shared five-minute cadence, blocking both reward buys and pot buys. The design document says no such griefable cooldown exists. Delay only, no loss.
• Info, Civic line 187. The war score adds chest points to raw district hash on different scales. A 300,000-token chest scores 100,000 against 24,000,000 of hash, and when the unfunded side wins the whole chest goes to the pool. Feature 0 is dormant at launch.
• Info, Season line 153. GridOperator is an admitted caller of recordSpend that no pinned path uses. Same class as the accepted unused-permission item.

All four specialist findings were confirmed at the severities they reported. The write_foundry_tests step and audit_flow reported nothing to merge. My own pass over the eight L4 contracts, FarmCore, FarmRewards, FarmItems, RewardPool, GameRegistry, EndowmentEscrow and Params found nothing further.

Coverage record. 159 rows, 109 holds, 6 pointing at findings, 44 unreached. The unreached rows are the L1 and L2 contracts outside this launch: PackSale, StarterClaim, V4Market, StandardMarket, StandardAdapter, MarketFactory and SwarmDesk. I did not trace those within the budget and have said so rather than inheriting the specialists' verdicts.
