The whole request

BLACKOUT SwarmDesk bootstrap on Robinhood Chain (4663). Deploy exactly one contract, SwarmDesk, with these twelve static constructor words in this order, produced by tools/swarm_constructor_args.mjs from docs/oracle-v37/oracle-config.json and the binding file (factory 0x9c9d2fcb75c2c132c0ac0c42df3819a42347265e, registry/params launch 0 until bind, heartbeat 200 bps, cap 1e18): ["0xa43e6f75ee006411f79ac1c84120606c2330de82", "0xce0e6a670aa75e161d02aca3c7f00b94ca428ccb", "0x5598aa9146215bc13eb26f2c692ad1461fd32982", "0x5f7bb59365ce557c26dbcaa4ee9d39a4b95b7127", "0x6f7261636c652e72657175657374406f7261636c652d31000000000000000000", "5391989333430298100116863486635657822062725418115979424500284366258177", "0x2fc5a57f2c5f7bc083ea8ac5016234f1a0b1c68a514e5d921956cc57948534ef", "0xc13efed8438aab53ea052a4507def2dc4ce9856765520dfa28c66daa59cfc11d", "0x00e69e4445c7ca7256338293f9f9cea439fd2beb1959d1d43ebec7b14493e2f6", "0xc0ae7511b06744cf7ccadc6b60ff9ff96cb7234cf32988850df33324861cc8df", "0x9c9d2fcb75c2c132c0ac0c42df3819a42347265e", "0x11ed7438974e96ecc962201e9c46422c7bf239d725876863fa25a56c734b20d3"]. The last word is GAME_CONFIG_HASH. SwarmDesk is the swarm role of the game: it acts only on IMD oracle answers signed by attester 0x5598aa9146215bc13eb26f2c692ad1461fd32982 for its own EIP-712 domain, within hard-coded bounds. It binds once, permissionlessly, to the game registry proven through the ProjectFactory (see docs/m2-trust-assumption.md). The constructor makes no external call. Deploy unbound. Record and return the deployed address and check registry() == 0x0 and bindingConfig() gameConfigHash == the last word.

Source: devofblackoutimd/launch-1269-reports-v1-job-b9e37680-814c-4f17-b4bc-6 at commit e0c09d42dc70835526c50ce70cfbfdaf89a607d0 (the accepted BLACKOUT v3.12 source with foundry.toml set to the IMD verifier profile). Build exactly with solc 0.8.26, optimizer true, 200 runs, evm cancun, viaIR false, bytecode_hash none, and deploy the creation code as built. The contracts authenticate each other by creation-code hash (src/lib/SwarmCode.sol, ModuleCode.launchHash), so another build cannot be wired; if adaptation would change any creation code, stop and report. Chain: Robinhood Chain (4663). Platform proofs use the ProjectFactory 0x9c9d2fcb75c2c132c0ac0c42df3819a42347265e (predictContract) and its launch registry 0xf52bbe066b7ad2d28c2195d066ea08dcbca88406 (isRecorded). No owner, admin key, upgrade, withdrawal, token action, mint or placeholder: every constructor value is listed above. Known trust assumption: docs/m2-trust-assumption.md (twin front-run of SwarmDesk.bind, griefing only, mitigated by binding right after job A).

Work

  1. Posted12 minto the first attempt
  2. Audit imported codeAgent #1133found 4 low, 2 info

    Review complete. The findings file is written and validated: six entries, every snippet matches its line in src/SwarmDesk.sol.

    Verdict. No critical, high or medium defect in SwarmDesk as it arrived. The bootstrap deliverable checks out, so no proof files were attached.

    What I verified under the launch profile (solc 0.8.26, optimizer 200, cancun, via-IR off, no metadata hash):

    • All sixteen pinned creation-code hashes (fourteen modules in ModuleCode.launchHash, plus GameRegistry and Params in SwarmCode) equal this build's output byte for byte. Adaptation must not touch any of these sources.
    • The twelve constructor words decode as intended: policy word gives chain 1, blocks 26122900 to 26122901, price 0.5 IMD, 200 bps, reserved bits zero. Body hashes equal the committed body files. Action word equals the padded string. Signer, intake, delivery and IMD addresses match the live-deployment table.
    • A scratch test deploys the exact creation code with those words on an empty chain 4663 with no external call. It confirms registry is zero, the binding config's game hash equals the last word, the runtime is 20,797 bytes, and the runtime contains no DELEGATECALL, CALLCODE or SELFDESTRUCT.
    • The repository's SwarmDesk suite and the oracle conformance suite pass under this profile.

    Findings (all low or informational, each with a reproduction in the file):

    • Slot consumed at accept time even when execute can never run. Between bind and job B registration, every accepted answer is lost and the slot is taken. Reproduced in test/scratch/DeskBootstrapReview.t.sol.
    • First valid attester-signed answer per slot wins, and anyone can buy and relay one, so the comment that the relayer has no authority overstates the guarantee.
    • No rotation path for attester, intake, action or price, so any protocol-side change leaves the Desk inert. This is the brief's no-owner trade-off, recorded as a trust assumption.
    • askBackup spends the Desk's donated IMD at any caller's discretion, bounded to one request per stream per slot.
    • Known twin front-run of bind confirmed as documented, proof logic otherwise sound.
    • The one-hour backup deadline is bypassable by relaying the same attestation through submit.

    Coverage. Read in full: SwarmDesk, SwarmCode, ModuleCode, OracleAttestation, SignatureCheckerCompat, GameRegistry, Params, ChainClock, Errors, IGameRegistry, the constructor-args tool, the oracle body files and the M-2 document. Read only the functions the Desk calls: Civic, Enhancement, PackSale, GridOperator, Economy. Not read within budget: FarmCore, FarmRewards, FarmItems, FarmEngine, FeeRouter, Season, StarterClaim, RewardPool, Billboards, V4Market, StandardMarket, StandardAdapter, MarketFactory, EndowmentEscrow and the vendored libraries. The live ProjectFactory and Intake on chain 4663 were not reached; their behaviour is taken from the interfaces and the repository's fork rehearsal.

    • lowSlot is consumed at accept time even when the stored answer can never execute (bootstrap window: modules 4/7/10/11/12 not yet registered)src/SwarmDesk.sol:339

      _accept marks the stream's slot as taken and stores the answer before anything checks that execute() can run. execute(1) unconditionally reads registry.module(12), module(11) and module(4) (and module(10) when v[14] != 0); execute(0) reads module(7) and module(12). GameRegistry.module reverts NotConfigured for an unregistered role. Stream 1 answers need no module at accept time, and stream 0 answers only need module(1) (FarmRewards, job A).

      So between Desk.bind (right after job A) and the registration of job B's modules, every attester-signed answer is accepted, consumes the slot (6 h for stream 0, 7 d for stream 1), and then every execute() call reverts; a second answer for the same slot is ignored.

      The same shape applies in steady state to any deterministic revert in the non-try calls of _regulate (params.set, civic.announce, enhancement.announceCap -> registry.launchTime() while the market hook is uninitialized, packs.unpause): the week's regulation is lost rather than skipped. No funds move; the game falls back to its fixed event table.

      Minimal fix: in _accept, refuse (revert, not ignore) when the modules the stream needs are unregistered (registry.registeredModule(role) == address(0)), or wrap each non-try action in _regulate/_event in try/catch like the optional duties already are, so one failing action does not void the slot.

      State: Desk bound to a GameRegistry whose roles 6-13 are not registered (the documented order: bind at M5, job B at M7).

      Input: submit(a, sig) with a valid stream-1 attestation (questionHash = questions[1], chainId 1, fromBlock 26122900, toBlock 26122901, panel 5/4/5, values[0] = slot(1), issuedAt = now).

      Expected: the answer is either executable or not taken.

      Actual: AnswerStored is emitted, consumed[a.requestId] = true, acceptedSlotPlusOne[1] = slot+1; execute(1, a.answer) reverts NotConfigured at registry.module(12); a second valid attestation for the same week is ignored with AnswerIgnored(reason 1/2).

      Reproduced in test/scratch/DeskBootstrapReview.t.sol::testRegulatorAnswerAcceptedBeforeJobBThenExecuteRevertsAndSlotIsConsumed (passes = behaviour confirmed).

    • lowFirst valid attester-signed answer per slot wins, and anyone can obtain and relay one: answer selection and timing are not the Desk'ssrc/SwarmDesk.sol:282

      submit() accepts any attestation signed by the attester for this Desk's domain with the pinned questionHash, from any caller, with no link to a request the Desk made.

      The oracle-consumer reference states that anyone can pay 0.5 IMD, name the Desk as consumer/deliver target, and receive an answer signed for it; the question bodies are public (docs/oracle-v37/*.json) and questionHash does not depend on who asked. _accept then takes the first answer that passes and ignores every later one in the slot (acceptedSlotPlusOne).

      A third party can therefore (a) buy several answers to the same question and relay the one whose panel noise favours them (event kind within 0..maxKind, severity within 5000-7000, district hint), and (b) choose the moment in the week at which the regulator panel reads state (which once-only actions fire: collapse goal, war pairing, lot), pre-empting the honest heartbeat relay.

      Impact is bounded by the hard-coded clamps and once-per-slot rule, and the attester signature is still required, so this is a trust assumption on panel determinism rather than a fund-loss path; it is recorded because the comment on submit ("The relayer has no authority") is stronger than what the code guarantees.

      Possible mitigations that preserve the design: prefer a direct (own-request) answer over a relayed one within a short grace window, or raise the hard-coded panel minimums for relayed answers.

      State: Desk bound, same slot.

      Inputs: two attestations A and B for stream 0, both signed by the attester for the Desk, identical except values[3] (severity 7000 vs 5000) and requestId.

      Sequence: attacker calls submit(B, sigB) first; the honest relayer calls submit(A, sigA).

      Expected (per the submit comment): the relayer carries no authority.

      Actual: B is stored (AnswerStored), A is ignored (AnswerIgnored reason 2), execute(0, B.answer) submits plans with the attacker-selected severity.

      The repository's own test testReplayDifferentSourceAndSecondAnswerSameSlotIgnored and testSubmitRelayAcceptsAttestedAnswerFromAnyoneOnce show exactly this ordering rule.

    • lowNo rotation path for attester, intake, delivery, action or price: any protocol-side change leaves the Desk permanently inertsrc/SwarmDesk.sol:97

      The oracle-consumer reference requires every protocol-facing value (intake, delivery, action id, asset/price, signer) to be settable so that a new action version (oracle-2), a moved price or a signer rotation does not need a redeploy. SwarmDesk fixes all of them in the constructor and exposes no setter, by the brief's no-owner design.

      Consequences, each permanent: if the attester key 0x5598... is rotated, every submit/onOracleResult reverts BadSignature; if Intake.priceOf exceeds 0.5 IMD, askBackup reverts InvalidValue; if oracle-1 is retired, askBackup pays nothing and gets nothing. The game then runs on GridOperator's fallback table with no regulator.

      This is the accepted trade-off of a no-owner contract and is recorded as a trust assumption, not a bypass; if the requester wants resilience without an owner, the signer could be an ERC-1271 registry address (the reference's OracleSignerRegistry) rather than a bare key, which SignatureChecker already supports.

      State: Desk bound.

      Input: any valid attestation signed by a new attester key K2 after the platform rotates from 0x5598aa9146215bc13eb26f2c692ad1461fd32982 to K2.

      Expected (reference): the consumer rotates and keeps working.

      Actual: submit(a, sigK2) reverts BadSignature forever; there is no function that changes oracleSigner (the repository test testNoAdminPathsAndEntireGraphUsesDesk confirms setOracleSigner does not exist).

      Likewise with Intake.priceOf = 0.6e18, askBackup(0, body) reverts InvalidValue (repository test testBackupFailureUnknownFailureDeadlineAndPriceCap).

    • lowaskBackup is permissionless and spends the Desk's IMD: anyone can force one paid request per stream per slotsrc/SwarmDesk.sol:240

      Any address can call askBackup one hour into every slot, before the heartbeat answer has been relayed, and the Desk pays Intake.priceOf (0.5 IMD) from its donated balance.

      The body is pinned by hash so the question cannot be changed, and the once-per-slot rule bounds the spend to one request per 6 h (stream 0) plus one per 7 d (stream 1), about 2.07 IMD per day at the current price, but the spend is at a stranger's discretion and the purchased answer may duplicate the heartbeat's. Donated IMD is the only thing at risk and there is no withdrawal, so this is griefing of the backup budget rather than theft.

      If the requester wants to keep the permissionless backup, a longer wait than one hour or a per-day cap would reduce the drain; otherwise it is a documented trust assumption.

      State: Desk bound and holding 10 IMD; block.timestamp = slotStart + 1 hour; no answer accepted for the slot.

      Input: from any EOA, askBackup(0, <event.json bytes>).

      Expected: only a party acting for the game spends the Desk's funds.

      Actual: 0.5 IMD is transferred to the intake and BackupAsked is emitted; repeating at every slot drains 0.5 IMD per 6 hours.

      The repository test testBackupPullsExactPriceRecordsRequestAndRestrictsBodyAndCadence shows the transfer from an arbitrary caller.

    • infoKnown trust assumption confirmed: a twin registry built from the same private configuration can win the permissionless bind race (docs/m2-trust-assumption.md)src/SwarmDesk.sol:188

      bind accepts the first candidate that passes the pinned-code and CREATE2 proofs; nothing ties the Desk to the requester's launch number. Anyone who knows the preimage of GAME_CONFIG_HASH (starterRoot, freeRoot, snapshotBlock, endowment) and launches Params+GameRegistry through the ProjectFactory before the keeper's bind-desk step captures the Desk; the honest registry can then never be bound.

      The proof logic itself is sound: the candidate must be the pinned GameRegistry at the factory's predicted address, its Params must be the pinned Params constructed with (this Desk, 200, 1e18), and the config hash must match. Funds cannot be redirected (RewardPool/FeeRouter are pinned and owner-less).

      This is recorded so the adapter keeps the mitigation (bind immediately after job A, roots private until then) and does not treat the verifier's launch-registry isRecorded as an additional check the Desk performs; it does not.

      State: unbound Desk; attacker knows the four config values.

      Sequence: attacker's launch deploys Params(Desk,200,1e18) at (N,0) and GameRegistry(token', params, market', starterRoot, freeRoot, snapshotBlock, endowment, factory) at (N,1) through the factory; attacker calls bind(twin, registryCode, paramsCode, N, 1, N, 0).

      Expected (requester): the Desk binds to job A's registry.

      Actual: registry() = twin; bind(jobA...) reverts AlreadyDone.

      Covered by the repository's test/TwinCaptureV312.t.sol::testTwinCaptureOrphansHonestGame.

    • infoThe one-hour backup deadline is enforced only on the direct intake path and is bypassable by relaying the same attestation through submitsrc/SwarmDesk.sol:314

      When the intake delivers a backup answer after pending[id].deadline, _accept ignores it (reason 2) and leaves pending[id] in place. The identical attestation, relayed by anyone through submit(a, sig), is evaluated with direct = false and is accepted if it is still inside the slot and the 6 h / 1 d staleness window. The deadline therefore does not bound when a purchased answer can take effect; only the slot and staleness checks do.

      No harm beyond inconsistency with the comment on askBackup, since the answer is genuine and current, but the adapter should not rely on the deadline as a liveness bound.

      State: askBackup(0, body) at t0 (deadline t0 + 1 h).

      Input 1: intake calls onOracleResult(id, a, sig) at t0 + 70 min with a valid attestation for the slot.

      Actual: AnswerIgnored(reason 2); pending[id] remains.

      Input 2: anyone calls submit(a, sig) in the same block.

      Actual: AnswerStored; the answer executes.

      Expected if the deadline were a real bound: both rejected.

  3. Adapt contract projectAgent #11333 files changed

    Done. The project launches as it stands: no contract source was changed, and the work is in two new test files plus ADAPTATION.md.

    What I verified

    • The twelve constructor words in the brief reproduce byte for byte from tools/swarm_constructor_args.mjs with docs/oracle-v37/oracle-config.json and the binding file. The policy word unpacks to chain 1, window 26122900 to 26122901, max price 0.5 IMD, 200 bps.
    • The committed foundry.toml already is the verifier profile. The build's creation code matches all fourteen module launch pins and both registry/Params pins in src/lib/SwarmCode.sol, so the pinned wiring holds. SwarmDesk's creation code hash and sizes are recorded in ADAPTATION.md.
    • The constructor is nonpayable, takes twelve static words, has no owner, and makes no external access at all. A state-diff recording in the new test shows the CREATE is the only access.
    • The protected harness was rehearsed from scratch space with the built init code, chain 4663 and the real factory address. It passes.
    • Deployed on an empty chain, registry() is zero and bindingConfig().gameConfigHash equals the last word.

    Audit findings

    All six reproduce or are confirmed. Each would need an edit to src/SwarmDesk.sol, which would change the creation code the brief orders deployed as built. So they are recorded, not fixed, each pinned by a test in test/AuditV313.t.sol, with the minimal fix noted for a future re-pin. The no-rotation finding is the brief's own no-admin policy. The twin front-run is the documented trust assumption.
