• 1.mediumGOLD reward journals are keyed by config id while the GOLD balance is per wallet: re-pinning deploymentBlock (new config id) re-credits every historical UTC dayworld-source/server/economy-ledger.ts:127

  if(reward===0n)continue;const reference=`${config.id}:${day}:${who}`;

  settleEconomy writes one utc-reward journal per (config.id, day, wallet) and the economy_gold_apply trigger (migrations/0010_world_economy.sql:109-113) folds every journal into economy_gold_accounts, which is keyed by wallet only. economy_chain_state, economy_positions, economy_gold_days and economy_day_progress are all scoped by config.id, and config.id is the SHA-256 of [rule, chainId, token, stakingContract, paymentContract, treasury, deploymentBlock] (economy-config.ts:43).

  A later release that changes deploymentBlock for the same deployed contracts (for example correcting a mis-pinned start block or moving it earlier to pick up an early deposit) yields a new config id with an empty cursor; the indexer re-ingests the same finalized Staked/Withdrawn events under the new id, settlement re-walks every completed day, inserts a second reward journal per (day, wallet) and the wallet's spendable GOLD doubles.

  Nothing in defineEconomyConfig, settleEconomy or the schema detects that the same chain events were already credited to the wallet. This violates REQUIREMENTS.md rules 3 and 7 (one GOLD per share-day; no path may mint arbitrary GOLD) through an ordinary operational configuration change rather than an attack.

  Prerequisite: an operator redeploys the Worker with a different deploymentBlock (or any config-id field) while keeping the same contracts; the economy-config.ts:42 comment shows only catalogue edits were considered. The existing tests never define two configs over the same contracts.

  Fix (preserves design): make the reward journal reference independent of deploymentBlock (e.g. chainId:stakingContract:day:wallet) or add a UNIQUE guard per (wallet, day) for utc-reward journals and treat a conflict as already credited, and/or have defineEconomyConfig refuse a stakingContract that already has economy_chain_state rows under a different config id. Merged from audit_flow; reproduced here.

  Run against tests/d1-sqlite.mjs (real migrations) with viem available: A=defineEconomyConfig({chainId:1,token:ECONOMY_TOKEN,stakingContract:S,paymentContract:P,treasury:ECONOMY_TREASURY,deploymentBlock:'100',catalogue:[]}); B=same with deploymentBlock:'99'.

  Ingest into A: block 100 (timestamp M = UTC midnight 2026-10-01) with one Staked(wallet W, positionId 1, shares 1, amount 1e23); block 101 at M+86400000 with no events; settleEconomy(db,A,{nowMs:M+86400001}) -> settledDays 1, economyWalletSnapshot(db,A,W).gold === '1'.

  Then into B: empty block 99 at M-1000, the identical block 100 event, block 101, settleEconomy(db,B,{nowMs:M+86400001}).

  Expected: W still holds 1 GOLD for the single complete share-day.

  Actual (script output on this tree): 'config A settledDays 1 GOLD now 1' then 'config B (deploymentBlock re-pinned) settledDays 1 GOLD now 2'; economy_gold_journal holds two utc-reward rows reward:<A.id>:1790812800000:W and reward:<B.id>:1790812800000:W, each delta 1.

• 2.lowIdempotent replay of an already-completed GOLD payment throws CHALLENGE_EXPIRED once the 5-minute challenge window has passed, so a client that lost the first response is told the debited payment failworld-source/server/economy-ledger.ts:229

  if(challenge.expiresMs<=now)throw new EconomyConflict('CHALLENGE_EXPIRED');

  payEconomyOrderGold is documented as replay-safe ('Replayed completion never adds a second journal/entitlement', line 212) and line 230 returns the paid order when existing.status==='paid' and goldRequestId matches the request.

  But the challenge-expiry guard on line 229 runs before that early return, so a retry of the identical (requestId, signature) after challenge.expiresMs (at most 5 minutes after issuance; the order itself stays valid for 15 minutes) throws CHALLENGE_EXPIRED although the debit, journal, fulfillment and challenge consumption already committed. handleEconomyApi maps it to HTTP 409; EconomyClient.payGold rejects, and EconomyPane.payGold (EconomyPane.tsx:52) never calls readAccount on the throw path, so the pane shows the generic 'Unable to finish' message for a payment that succeeded until the player manually refreshes the ledger.

  No funds are duplicated or lost (balance stays decremented exactly once).

  Fix: evaluate the existing.status==='paid' && goldRequestId===requestId short-circuit before the challenge expiry/consumed checks (keep signature, clock lower-bound and idempotency-conflict checks). Merged from audit_economics and audit_flow (same root cause, same line); reproduced here.

  Replay the identical call with nowMs t0+100000 -> returns status 'paid' (idempotent).

  Replay the identical call with nowMs = challenge.expiresMs (t0+301000, order still valid until t0+900000).

  Expected: the paid order is returned exactly as the +100s replay.

  Actual (script output on this tree): 'replay at challenge.expiresMs -> threw CHALLENGE_EXPIRED | order status in DB: paid | balance 4'.

• 3.lowEmbeoPayments.pay marks (payer, orderId) paid for any nonzero amount, so one wrong-amount payment forwards unrefundable EMBEO to the treasury and permanently blocks the exact payment for that ordercontracts/src/EmbeoPayments.sol:30

  paid[msg.sender][orderId] = true;

  pay(orderId, amount) accepts any nonzero amount, sets paid[msg.sender][orderId] before transferring, and forwards the tokens to the immutable treasury. The contract cannot know the server quote, and the backend fulfils only a finalized Paid event whose amount equals the immutable order amount (economy-ledger.ts:62 UPDATE ... AND amount=?; economy-staging.ts:54 fold).

  A payment with a different amount is therefore indexed as an event that matches no order, the order stays 'pending', the tokens sit in the treasury with no refund entry point (contracts are ownerless and immutable by design), and a second call with the correct amount from the same wallet reverts OrderAlreadyPaid.

  Prerequisite: the payer calls pay() directly (block explorer, script, wallet that lets the user edit calldata, or a third-party/buggy client) with an amount other than order.amount; the shipped EconomyPane/EconomyWalletController always encodes the exact server amount and checks paid() before prompting (economyWallet.ts:110,140), and the mapping is per payer so no third party can block another wallet's order.

  It still means the rule-11 promise that 'a successful exact EMBEO payment is reconciled from its finalized receipt' becomes impossible for that order after one mistake, and nothing server-side flags the stranded tokens.

  Design-preserving mitigation: key the replay guard on (payer, keccak256(orderId, amount)) so the exact payment remains possible while exact replays stay blocked (server matching already requires wallet+orderId+amount and paid_event_id is UNIQUE, so no double fulfilment), and/or record indexed payment events whose (wallet, orderId) match a pending order with a different amount so operators can reconcile.

  Merged from audit_permissions, audit_economics and audit_flow (identical mechanism); reproduced by Foundry test in a scratch project (see reproduction).

  Deploy AdversarialToken (contracts/test/AdversarialToken.sol, plain 18-decimal fixed-supply token) and EmbeoPayments(token, treasury).

  Server order X quotes amount 1e18 for payer W.

  W approves 2e18 and calls pay(X, 1): succeeds, Paid(X, W, token, treasury, 1) is emitted, treasury balance +1 wei, paid(W, X) == true.

  Indexer: event amount '1' != order amount '1000000000000000000', so economy_orders stays 'pending' and no economy_fulfillments row is written.

  W then calls pay(X, 1e18).

  Expected (rule 11): the exact payment can still be made and reconciled.

  Actual: revert OrderAlreadyPaid(); order X can never be fulfilled by W and the 1 wei is not refundable (no admin/rescue function exists).

  Scratch forge test run on this tree: forge test on a test that expects the second pay(X,1e18) to succeed fails with OrderAlreadyPaid().

• 4.infoIdempotent order replay returns an expired pending quote rather than ORDER_EXPIREDworld-source/server/economy-ledger.ts:197

  if(previous){if(previous.payload!==payload)throw new EconomyConflict('IDEMPOTENCY_CONFLICT');const {payload:_,...order}=previous;return order;}

  createEconomyOrder returns the previously stored order for the same (wallet, requestId) without checking expires_ms.

  EconomyPane keeps orderAttempt (same requestId) for the same service/currency until the order is paid or renewOrder clears it, so a client that re-selects the same service later receives a pending order whose expiresMs is already past; the following GOLD challenge request then fails with ORDER_EXPIRED, and an EMBEO plan fails client-side with INVALID_ORDER (economyWallet.ts:101).

  No funds are at risk: an expired EMBEO quote is immutable and a late exact Paid event still fulfils it, and GOLD challenges cannot be issued on an expired order. The pane recovers through its expired-order notice and renewOrder. Returning ORDER_EXPIRED (or a fresh quote) on replay of an expired pending order would remove the timestamp-detection burden from clients.

  From audit_economics; reproduced here.

  whole finding

  createEconomyOrder(db,config,{wallet:W,requestId:'q'.repeat(20),serviceId:'svc',currency:'EMBEO',nowMs:D0}) then the same call with nowMs:D0+86400000.

  Actual (script output on this tree): 'same id true status pending expiresMs<nowMs true', i.e. the same order id is returned with status pending and expiresMs (D0+900000) < nowMs.

• 5.infoTrust assumption: immutable supply and code-hash binding turns any EMBEO supply/runtime change into permanent loss of withdrawals; mainnet runtime readback was not performed in this reviewcontracts/src/ExactEmbeo.sol:32

  if (address(token).codehash != tokenCodeHash || token.totalSupply() != tokenSupply) revert TokenChanged();

  Not a bypass. Every deposit, pay and withdraw first requires the token's current codehash and totalSupply to equal the values captured at construction. If mainnet EMBEO ever differs from the public fixture (contracts/fixtures/embeo-token-artifact.json: fixed-supply ERC-20 with no mint/burn/pause/proxy), a single supply change would make withdraw() revert forever and lock all principal, contradicting 'durable halt must not confiscate principal' at the contract layer.

  The binding is the requested token-identity check and should stay; the release gate must run contracts/tools/preflight.mjs against mainnet (runtime hash, decimals, totalSupply 1e27) and record the readback. This review made no mainnet RPC call, so the deployed token runtime, vault/payment immutables and deployment readback remain unverified release blockers. From audit_permissions.

  State: any vault with staked principal.

  Input: token.totalSupply() returns a value different from the immutable tokenSupply (AdversarialToken.changeSupply() in contracts/test/AdversarialToken.sol, or a real token exposing burn()/an upgraded proxy).

  Call withdraw(positionId, 1).

  Expected per REQUIREMENTS rule 5: principal is refundable at any time.

  Actual: revert TokenChanged() on every call, permanently.

1. Posted5 minto the first attempt
2. Audit mathAgent #1981found nothing

   I found no math defect I could back with a failing input, so .imd-findings.json is {"findings":[]}. That isn't proof the code is free of defects, and the coverage gaps listed below still apply.

   Both the Solidity and the TypeScript/D1/client economic boundaries were reviewed, but only for this task's area: math precision, boundaries and numerical gaps. I did not run any tests. The repo's Node test suite and Foundry tests weren't executed because world-source/node_modules isn't installed and I didn't install it. No Solidity finding was high enough to need a proof test.

   Solidity (EmbeoStakingVault.sol, EmbeoPayments.sol, ExactEmbeo.sol)

   • Stake/withdraw math: shares * SHARE_SIZE is computed the same way on deposit and withdrawal, so they balance. It's checked arithmetic, so an oversized value reverts rather than wrapping. Shares are subtracted only after the owner and available-shares checks.
   • Exact-transfer checks: _transferExact checks the before/after balances on both sides and the total supply. No subtraction can underflow because a pre-check guards it.
   • Supply binding: the immutable supply check can't freeze principal for this token. I read mainnet totalSupply() through a public RPC: 1e27 wei (1,000,000,000 EMBEO). The pinned fixture says the token has a fixed supply and no mint or burn function.
   • Function selectors: every selector hard-coded in the client (economyWallet.ts:7) appears in the compiled runtime bytecode of the matching artifact.

   Off-chain ledger, indexer and client

   • Integer limits: every limit is checked before anything is written.
     • Event shares are capped at the SQLite 64-bit maximum (economy-rpc.ts:61).
     • Block timestamps are capped at MAX_SAFE/1000 before being multiplied by 1000 (:44).
     • logIndex is capped at 2³¹−1.
     • Share × amount equality is checked with BigInt at decode time (economy-rpc.ts:62) and again on ingest (economy-ledger.ts:31).
     • Amounts are canonical decimal strings with no leading zeros, so the amount=? text comparison in the order-payment update is exact.
     • The position padding has exactly 78 zeros, which fits the longest uint256.
   • UTC day boundaries:
     • A position counts for day D only if it was deposited at or before D 00:00 (deposited_ms<=day). A midday deposit starts the next day, matching ceil(first/DAY) and the client's firstEconomyDay.
     • The shares counted are those remaining at the last balance row before the day ends (at_ms<end). Shares only ever decrease within a position, so this equals the minimum held that day: only withdrawn shares lose the day. A withdrawal at exactly 00:00 counts against the new day, not the previous one.
     • A day is credited only when the indexed finalized time is at least the end of that day (through_ms>=end).
   • Settlement paging: position IDs are sorted and paged as text, consistently. Positions moving from open to closed between pages stay in the correct branch. A carried partial reward can't skip a wallet or credit it twice, and the position ceiling stops later deposits from joining an old day.
   • Overflow and capacity, using the measured supply:
     • The supply allows at most 10,000 shares in total, so rewards are at most 10,000 GOLD per day. No GOLD balance can reach the signed 64-bit limit.
     • The one-minute cron with 64 positions and 32 wallets per run gives about 92,160 position-days and 46,080 wallet-days per day, which is more than the 10,000 possible positions or wallets. So settlement can't fall permanently behind.
   • GOLD debit and clock checks:
     • -CAST(amount) stays within range.
     • balance>=0 is enforced by a CHECK constraint, so GOLD can't go negative.
     • A server clock that runs backwards is rejected before any write, with no clamping: challenge creation rejects a time before the order (economy-ledger.ts:182), and the debit rejects a time before the order or the challenge (:228).

3. Audit permissionsAgent #1925found 1 low, 2 info

   The review is complete and the findings file is written and validated. The working tree is unchanged apart from the ignored findings file.

   Outcome. Both the Solidity custody/payment contracts and the TypeScript/D1/client economic boundary were reviewed at commit 143ac7e. I found no critical, high, or medium defect. The ledger, finalized-chain ingestion, GOLD debit path, and client send controller held up against the rules in REQUIREMENTS.md and against adversarial probes.

   Findings written to .imd-findings.json:

   • Low, EmbeoPayments.pay. The replay guard is keyed on payer and order only, so a direct call with the wrong amount consumes the order's pay slot. The exact payment then reverts with OrderAlreadyPaid, the order can never be fulfilled, and the mistaken tokens sit in the treasury with no refund route. The shipped UI always encodes the exact amount, so this needs a manual contract call. Suggested fix keeps the design: key the guard on the order and amount tuple, and have the indexer flag mismatched payments for operator reconciliation.
   • Info, ExactEmbeo supply binding. Any EMBEO supply or code change would brick withdrawals forever. The public fixture is a fixed-supply token with no mint, burn, or delegatecall, so this is a trust assumption, but the mainnet runtime was not read back in this review.
   • Info, coverage statement. Records exactly what was verified and what remains open.

   What was verified locally:

   • Selected-source manifest matches all 71 files. Every line of contracts/SHA256SUMS matches. Artifacts equal the frozen baseline.
   • Recompiling the stored compiler input with the vendored official solc 0.8.37+commit.f401782d reproduced bytecode, deployed bytecode, and ABI byte-for-byte under optimizer 200, viaIR false, Cancun, no metadata hash.
   • The packet's ledger, settlement, adversarial, API, staging, and RPC tests passed 81 of 81.
   • Custom probes against the real SQLite migrations confirmed the UTC rules: midday deposits start the next day, a deposit exactly at midnight counts that day, a withdrawal exactly at the next midnight keeps the prior day, a withdrawal one second before midnight forfeits it, a closed-then-redeposited position inherits nothing, settlement never runs ahead of the indexed horizon, and 70 lots of one wallet page correctly.

   Not verified, still release blockers: mainnet EMBEO runtime and supply readback, deployed immutables, the excluded full-Worker test, real Workers CPU and D1 capacity, provider log completeness below the finalized head, and real wallet extension replacement behaviour. Tests ran on Node 22 rather than the pinned Node 24, so the packet's official runner receipt was not reproduced.

   • lowEmbeoPayments.pay marks an order paid for any amount, so one mis-amount payment permanently blocks the correct payment and strands the tokenscontracts/src/EmbeoPayments.sol:30

     The replay guard is keyed only on (payer, orderId) and is set before the amount is compared with anything. The contract cannot know the server quote, so any nonzero amount consumes the payer's single pay slot for that order.

     The server ledger (world-source/server/economy-ledger.ts:62 and economy-staging.ts:54) only fulfils an order when the finalized Paid event carries exactly the quoted amount, so a payment with the wrong amount is indexed as an event but never matches the order, and a second call with the right amount reverts with OrderAlreadyPaid. The treasury keeps the mismatched tokens, there is no refund entry point (contracts are immutable, no admin), and the order can never become 'paid'.

     Prerequisite: the payer must call pay() directly (wallet UI, etherscan, script) with an amount other than order.amount; the shipped EconomyPane/economyWallet controller always encodes the exact server amount, so this is user error or a third-party integration error, not an attack on other users.

     It still violates rule 11 ('a successful exact EMBEO payment is reconciled from its finalized receipt') in the sense that the exact payment becomes impossible after one mistake, and there is no server-side flag for operators to detect the stranded funds.

     Minimal fix preserving the design: key the replay guard on the exact tuple, e.g. mapping(address payer => mapping(bytes32 key => bool)) with key = keccak256(abi.encode(orderId, amount)), so a later exact payment still fulfils the order while exact replays stay blocked (server matching is already exact on wallet, orderId and amount, and paid_event_id is UNIQUE so double fulfilment cannot occur).

     Separately, have the indexer record payment events whose (wallet, orderId) match a pending order but whose amount differs, so operators can reconcile refunds.

     whole finding

     State: server order {wallet: P, currency: EMBEO, amount: 100000000000000000000, status: pending}.

     Step 1: P calls pay(orderId, 1) after approving 1 wei: succeeds, Paid(orderId, P, token, treasury, 1) emitted, paid[P][orderId] == true.

     Step 2: indexer ingests the event: UPDATE economy_orders ...

     AND amount='100000000000000000000' matches nothing, order stays pending.

     Step 3: P calls pay(orderId, 100000000000000000000): expected (per rule 11) the exact payment is accepted and the order is fulfilled from its finalized receipt; actual: revert OrderAlreadyPaid(), order can never be fulfilled, and 1 wei (or any mistaken amount) sits in the treasury with no refund route.

     Local check: deploy EmbeoPayments against the AdversarialToken/fixture token in contracts/test/runtime.mjs, approve 1, call pay(id,1), then approve 100000e18 and call pay(id,100000e18): second call reverts with OrderAlreadyPaid.

4. Audit flowAgent #1572found 1 medium, 2 low

   The review is complete and .imd-findings.json holds three substantiated findings. The working tree is otherwise unchanged (git status shows only the untracked findings file, which is the deliverable).

   Scope actually reviewed. Both economic boundaries were read in full: the three Solidity contracts, and the TypeScript server (API, ledger, settlement, staging, finalized RPC indexer, migrations 0010/0011) plus the client controller, response validator and pane. Existing auth/ownership/gateway modules were treated as dependency context only, as the scope file instructs. The full-Worker suite, production D1 capacity, real wallet UX and mainnet deployment remain unreviewed and unprovable here.

   Findings written to the file

   • Medium, GOLD double-credit across config ids (world-source/server/economy-ledger.ts:127). Reward journals are keyed by config id, but the wallet balance has no config dimension. A re-pinned deploymentBlock yields a new config id that re-indexes the same chain events and re-issues every historical day. Reproduced on the real migrations: one share-day produced a balance of 2 GOLD.
   • Low, idempotent replay broken after the challenge window (economy-ledger.ts:229). A retry of an already-committed GOLD payment throws CHALLENGE_EXPIRED instead of returning the paid order. Reproduced with a real signature.
   • Low, wrong-amount pay burns the order for that payer (contracts/src/EmbeoPayments.sol:30). Not third-party exploitable, but unrecoverable for the payer.

   Checks that passed

   • Mainnet EMBEO runtime at the pinned address hashes to the fixture, exposes only plain ERC-20 functions, has no mint/burn/pause surface, and reports 18 decimals. The vault's codehash and totalSupply binding therefore cannot be tripped by a third party.
   • Contract sources, OpenZeppelin 5.4.0 dependency files and the vendored solc payload match the recorded hashes. An independent forge compile with solc 0.8.37, Cancun, optimizer 200, viaIR off reproduced the ABI and runtime bytecode exactly, apart from the 12-byte CBOR solc-version tail.
   • Reentrancy, exact balance deltas, custody separation, order replay, payer/amount/receiver matching, finalized header continuity, reorg halt, receipt-log binding, atomic staging fold, server-clock lower bounds, GOLD signature binding and the client's nonce-bound intent and Web Lock flow all held up under reading and targeted probes. The shipped ledger test file passed 15/15 locally.

   Not done. No Foundry proof files were needed because no critical or high Solidity defect was found. Settlement load behaviour under Workers 50 ms CPU and D1 limits, large-receipt handling against a real provider, and the private full-World gate were not measured.

   • mediumGOLD reward journals are keyed per config id while the GOLD balance is per wallet: re-pinning deploymentBlock (or any config field) re-credits every historical UTC dayworld-source/server/economy-ledger.ts:127

     settleEconomy writes one reward journal per (config.id, day, wallet) and the economy_gold_accounts trigger folds every journal into a single wallet balance that has no config dimension (migrations/0010_world_economy.sql:92-113). economy_chain_state, economy_positions, economy_gold_days and economy_day_progress are all scoped by config.id, and config.id is the digest of [rule, chainId, token, stakingContract, paymentContract, treasury, deploymentBlock] (economy-config.ts:44).

     Any later release that changes deploymentBlock for the same deployed contracts (for example correcting a wrongly pinned start block, or moving it earlier so an early deposit is picked up) produces a new config id with an empty cursor.

     The indexer then re-ingests the same finalized Staked/Withdrawn events under the new id, settlement re-walks every completed day and inserts a second reward:<newConfigId>:<day>:<wallet> journal for each of them, and the wallet's spendable GOLD doubles. Nothing in defineEconomyConfig, settleEconomy or the schema prevents two configs for the same stakingContract from co-existing or detects that the same chain events were already credited.

     This violates REQUIREMENTS.md rules 3 and 7 (one GOLD per share-day; no path may mint arbitrary GOLD) through an ordinary operational change; the comment at economy-config.ts:43 ("Price changes do not reset finalized chain cursors") shows only catalogue edits were considered.

     Fix: make the reward reference independent of deploymentBlock (e.g. key journals by chainId:stakingContract:day:wallet, or add a UNIQUE index on utc-reward journals per (wallet, day) and have settlement treat a conflict as already-credited), and/or make defineEconomyConfig refuse to index a stakingContract that already has economy_chain_state rows under a different config id. The existing tests never define two configs over the same contracts, so this path is untested.

     whole finding

     Using tests/d1-sqlite.mjs (real migrations): A=defineEconomyConfig({chainId:1,token:EMBEO,stakingContract:S,paymentContract:P,treasury:T,deploymentBlock:'100',catalogue:[]}); B=same but deploymentBlock:'99'.

     Ingest into A: block 100 (timestamp = UTC midnight M) containing one Staked(wallet W, positionId 1, shares 1, amount 1e23); block 101 at M+86400000 with no events; settleEconomy(db,A,{nowMs:M+86400001}).

     Then into B: empty block 99, the identical block 100 event, block 101, settleEconomy(db,B,...).

     Expected: wallet W holds 1 GOLD for the single complete share-day.

     Actual: economyWalletSnapshot gold = '2'; economy_gold_journal holds two utc-reward rows for the same day and wallet (reward:<A.id>:M:W and reward:<B.id>:M:W).

     Script run on this tree printed: 'config A settledDays 1 GOLD now 1' then 'config B (deploymentBlock re-pinned) settledDays 1 GOLD now 2'.

   • lowIdempotent replay of an already-completed GOLD payment fails with CHALLENGE_EXPIRED once the 5-minute challenge window has passed, so a client that lost the first response is told the payment failedworld-source/server/economy-ledger.ts:229

     payEconomyOrderGold is documented as replay-safe ("Replayed completion never adds a second journal/entitlement") and line 230 returns the paid order when existing.status==='paid' and goldRequestId matches.

     But the challenge-expiry guard on line 229 runs before that early return, so a retry of the identical (requestId, signature) after challenge.expiresMs (at most 5 minutes after issuance) throws CHALLENGE_EXPIRED even though the debit, journal and fulfillment already committed.

     The pane maps the unknown code to the generic 'Unable to finish' error and never calls readAccount on the throw path (EconomyPane.tsx:52), so a player whose first POST response was lost (network drop, tab reload after the signature, Worker timeout after commit) sees a failure for a payment that was debited; refreshing the ledger is the only way to learn it succeeded. No funds are duplicated or lost; this is a consistency/UX defect on the documented idempotence path.

     Fix: move the existing.status==='paid' return (line 230) above the clock and expiry checks, or exempt an already-paid order with a matching goldRequestId from CHALLENGE_EXPIRED.

     whole finding

     With tests/d1-sqlite.mjs: seed wallet W with 5 GOLD, createEconomyOrder (GOLD, price 1) at t0, createEconomyGoldChallenge at t0, sign challenge.message with W's key, payEconomyOrderGold(...,{requestId,signature,nowMs:t0,now:()=>t0}) -> status 'paid', balance 4.

     Call payEconomyOrderGold again with the identical requestId and signature but now = challenge.expiresMs (t0+300000, order still valid until t0+900000).

     Expected: the paid order is returned (idempotent replay).

     Actual: throws EconomyConflict('CHALLENGE_EXPIRED') while economy_orders.status is already 'paid'.

   • lowEmbeoPayments.pay marks the (payer, orderId) pair paid for any amount, so a mis-amount payment sends EMBEO to the treasury with no fulfillment and permanently blocks a correct payment for that order fcontracts/src/EmbeoPayments.sol:30

     pay(orderId, amount) accepts any non-zero amount and sets paid[msg.sender][orderId] before transferring. The server fulfils only an event whose amount equals the quoted order amount (economy-ledger.ts:62, economy-staging.ts fold UPDATE), so a payment with the wrong amount is irrecoverable: the tokens reach the immutable treasury, the order stays 'pending', and a second, correct pay(orderId, exactAmount) from the same wallet reverts with OrderAlreadyPaid.

     The bundled client always encodes the server amount, so this is only reachable by a wallet/UI that lets the user edit calldata, by a manual contract call, or by a client bug; no third party can trigger it against a victim (the mapping is per payer). It is a design limitation worth documenting or hardening (no refund role exists by design).

     Possible mitigation without adding admin power: have the contract bind the amount into the replay key (paid[msg.sender][keccak256(orderId, amount)]) or let the server-issued order id commit to the amount so a mismatched event can be reconciled by a new quote; at minimum the client/README should state that a wrong-amount payment is unrecoverable.

     whole finding

     Deploy EmbeoPayments(token, treasury) with a fixed-supply 18-decimal token; wallet W holds and approves >= 2 units.

     Server order X quotes amount A=1e18.

     W calls pay(X, 1) -> succeeds, Paid(X, W, token, treasury, 1) emitted, 1 wei moved to treasury, paid[W][X]=true.

     Indexer: event amount '1' != order amount '1000000000000000000' so economy_orders row stays 'pending' (no fulfillment).

     W then calls pay(X, 1e18) -> reverts OrderAlreadyPaid.

     Expected per rule 11 ("successful exact EMBEO payment is reconciled"): some path for W to complete order X.

     Actual: order X can never be fulfilled by W and the 1 wei is not refundable; W must obtain a new order (new requestId) and pay again.

5. Audit economicsAgent #253found 1 low, 2 info

   Tree is clean again. The rewritten artifact only recorded the local runtime (Node version, platform, native EDR package); the pinned compiler payload hash and every source/ABI/bytecode hash matched the frozen baseline, which is why the projection check and all 29 contract tests passed.

   Outcome

   The findings file .imd-findings.json holds three entries: one low-severity defect and two informational notes. No critical or high finding was substantiated in either the Solidity or the TypeScript/D1/client economic boundary, so no Foundry proof file was written. Both boundaries were reviewed.

   What was checked and passed

   • Solidity (EmbeoStakingVault, EmbeoPayments, ExactEmbeo): ownerless custody, exact balance-delta and supply/codehash binding, nonReentrant plus checks-effects-interactions, position ownership on withdraw, per-payer order replay guard, immutable treasury. The EMBEO fixture is a fixed-supply ERC-20 with no mint or burn selector, so the totalSupply binding cannot brick withdrawals.
   • Indexer (economy-rpc.ts, economy-staging.ts): finalized-head identity and optional witness, parent-hash chain over every header in a page, anchor re-read before commit, canonical receipt status and exact log equality, allowlisted methods, bounded bisection, busy-block staging with atomic fold, reorg halt.
   • Ledger (economy-ledger.ts, migrations): contiguous cursor CAS, immutable event and journal triggers, non-negative GOLD CHECK, atomic debit/order/challenge batch, clock lower bounds, late EMBEO payments fulfilling immutable quotes.
   • Client (economyClient.ts, economyWallet.ts, EconomyPane.tsx): canonical challenge revalidation before and after signing, no token RPC for GOLD signing, intent persisted before the wallet prompt under a Web Lock, replacement proof requiring finalized inclusion, fail-closed locks and storage.

   Local verification

   Suite	Result
   Contract tests (EDR 31337, official solc 0.8.37)	29/29 pass
   Selected financial tests	188/188 pass
   Source manifest bytes	match

   My own adversarial scripts confirmed the UTC-day rules: a midday deposit earns nothing that day, partial withdrawal forfeits only the withdrawn shares, a closed lot is excluded, a 65-position wallet settles correctly across pages, and a same-block stake plus withdrawal folds correctly through staging.

   Findings

   1. Low. A replay of a completed GOLD payment with the same request and signature, arriving after the 5-minute challenge window, returns CHALLENGE_EXPIRED instead of the paid order. No double debit occurs, but the client shows a failure for a payment that succeeded. Reordering the already-paid short-circuit ahead of the expiry check fixes it.
   2. Info. Idempotent order replay returns an expired pending quote rather than ORDER_EXPIRED. The pane recovers via its expired-order flow.
   3. Info. A wrong-amount manual pay() call forwards tokens to the treasury and permanently blocks the exact retry for that payer. This is the documented design and is reachable only by bypassing the client.

   Scope gaps and release notes

   • The economy is not enabled: the deployment gate returns null, so no mainnet runtime, immutable readback, or production reward issuance was verified. Those remain preconditions before enabling real funds.
   • The full Worker and renderer test gate is private and was not run. Workers 50 ms CPU, D1 capacity, large receipts, and real wallet extension behavior are not established by desktop timing.
   • The documented engineering ceiling stands: a valid finalized block with more than 10,000 matching logs, or an RPC provider log limit on a single block, stalls the cursor rather than crediting anything.
   • Below the announced finalized height the indexer trusts RPC ancestry and log completeness. No independent finality proof exists, as the code itself states.

   • lowReplayed GOLD payment completion after challenge expiry returns CHALLENGE_EXPIRED instead of the already-paid orderworld-source/server/economy-ledger.ts:229

     payEconomyOrderGold checks the challenge expiry (line 229) before the already-paid short-circuit (line 230). A legitimate retry of the same requestId/signature (network retry, pane reopen, duplicate click resolved late) that arrives more than the 5-minute challenge window after issuance is answered with 409 CHALLENGE_EXPIRED even though the debit, journal, fulfillment and challenge consumption already committed.

     The ledger stays correct (no second debit, balance unchanged), but the documented idempotent contract ("Replayed completion never adds a second journal/entitlement" and returns the order) is broken for late replays: EconomyClient.payGold surfaces an error and the pane shows a failed-payment message for a payment that succeeded, until the player manually refreshes the ledger.

     Fix: evaluate the existing.status==='paid' && goldRequestId===requestId short-circuit before the challenge expiry/consumed checks (keep the signature and clock lower-bound checks), so a replay returns the paid order regardless of elapsed time.

     5. Call payEconomyOrderGold again with identical arguments but nowMs:t0+2000+301000.

     Expected: returns the paid order (idempotent replay, exactly as the same call at nowMs:t0+102000 does, returning status paid).

     Actual: throws EconomyConflict CHALLENGE_EXPIRED (HTTP 409 via handleEconomyApi).

     Balance remains decremented by exactly 2 in both cases, so there is no double debit.

   • infoIdempotent order replay returns an expired pending quote rather than ORDER_EXPIREDworld-source/server/economy-ledger.ts:197

     createEconomyOrder returns the previously stored order for the same (wallet,requestId) without checking expires_ms. A client that reuses its requestId (EconomyPane keeps orderAttempt for the same service/currency until the order is paid or renewOrder clears it) receives a pending order whose expiresMs is already past; the following challenge request fails with ORDER_EXPIRED and an EMBEO plan fails client-side with INVALID_ORDER.

     No funds are at risk: an expired EMBEO quote is immutable and a late exact Paid event still fulfils it, and GOLD challenges cannot be issued on it. The pane recovers through the expired-order notice and renewOrder. Returning ORDER_EXPIRED on replay of an expired pending order would remove the timestamp-based detection burden from clients.

     createEconomyOrder(db,config,{wallet,requestId:'q'.repeat(20),serviceId:'svc',currency:'EMBEO',nowMs:D0}) then the same call with nowMs:D0+86400000.

     Expected: ORDER_EXPIRED conflict or a fresh quote.

     Actual: the same order id is returned with status pending and expiresMs (D0+900000) < nowMs.

   • infoA wrong-amount pay() permanently marks the order paid for that payer and forwards tokens without fulfilmentcontracts/src/EmbeoPayments.sol:29

     pay(orderId, amount) records paid[msg.sender][orderId]=true for any non-zero amount and forwards the tokens to the immutable treasury. The backend fulfils only an event whose amount equals the immutable quote, so a manual or buggy call with a different amount both forfeits the tokens (no refund path exists by design) and makes the correct-amount retry for the same order impossible from that wallet (OrderAlreadyPaid).

     The reviewed client always encodes the exact server amount and checks paid() before prompting, so this is reachable only by bypassing the client. This is the documented design (Calling pay does not grant a service) and is recorded as a trust/UX assumption, not a release blocker. A design-preserving mitigation is to key paid by (payer, orderId, amount), or to let the backend accept a later exact payment for the same order.

     EDR/Foundry: deploy the token fixture and EmbeoPayments(token, treasury).

     Payer approves 2e18 and calls pay(orderId=0x11..11, 1e18) while the server quote is 2e18.

     Then payer calls pay(0x11..11, 2e18).

     Expected from the payer's perspective: the exact payment can still be made.

     Actual: the second call reverts OrderAlreadyPaid(); 1e18 EMBEO sits in the treasury and the server never marks the order paid because the event amount 1e18 differs from the order amount 2e18.

   Outcome: 6 findings recorded in .imd-findings.json, every one reproduced against the pinned tree. No critical or high defects were found, so no Foundry proof attachments were needed. Both the Solidity and the TypeScript/D1/client economic boundaries were reviewed.

   Kept findings, after merging duplicates

   • Medium, reward re-credit on config re-pin (world-source/server/economy-ledger.ts:127). Reward journals are keyed by config id, but the GOLD balance is per wallet. Re-pinning deploymentBlock for the same contracts produces a new config id, re-indexes the same events, and doubles every wallet's historical GOLD. Reproduced: a one-share day settled to 1 GOLD under config A and 2 GOLD after config B re-indexed the identical block. This is the one material fix before launch.
   • Low, late replay of a completed GOLD payment (economy-ledger.ts:229). The challenge-expiry check runs before the already-paid short-circuit, so a retry after the 5-minute window gets CHALLENGE_EXPIRED although the debit committed. Merged from two specialists. Reproduced: balance stays at 4, order is paid, replay throws.
   • Low, wrong-amount pay() strands tokens and blocks the exact payment (contracts/src/EmbeoPayments.sol:30). Merged from three specialists. Reproduced with a scratch Foundry test outside the repo using solc 0.8.37: the second exact pay() reverts OrderAlreadyPaid. Reachable only by bypassing the shipped client.
   • Info, expired quote returned on idempotent order replay (economy-ledger.ts:197). Reproduced; no funds at risk.
   • Info, trust assumption on supply/code-hash binding (contracts/src/ExactEmbeo.sol:32). Any supply change locks withdrawals forever, so mainnet readback is a release gate.
   • Info, coverage statement listing what was verified and what remains unverified.

   Verification run on this tree: all 39 contract hash sums match, the selected-source manifest matches, and 156 of 162 economy tests pass out of tree. The 6 failures are gaps in my review environment, namely missing EDR contract runtime, missing TypeScript package and no Web Locks on Node 22, not code defects. Extra probes confirmed the UTC day rules, single debit under concurrent challenges, wrong-signer and insufficient-balance rejection, and clock-rollback rejection before any write.

   Not verified, remaining release blockers: mainnet EMBEO runtime and deployed immutables readback, the full-Worker gate, real Workers CPU and D1 capacity, real wallet-extension replacement behaviour, and the absent production catalogue.

   • mediumGOLD reward journals are keyed by config id while the GOLD balance is per wallet: re-pinning deploymentBlock (new config id) re-credits every historical UTC dayworld-source/server/economy-ledger.ts:127

     settleEconomy writes one utc-reward journal per (config.id, day, wallet) and the economy_gold_apply trigger (migrations/0010_world_economy.sql:109-113) folds every journal into economy_gold_accounts, which is keyed by wallet only. economy_chain_state, economy_positions, economy_gold_days and economy_day_progress are all scoped by config.id, and config.id is the SHA-256 of [rule, chainId, token, stakingContract, paymentContract, treasury, deploymentBlock] (economy-config.ts:43).

     A later release that changes deploymentBlock for the same deployed contracts (for example correcting a mis-pinned start block or moving it earlier to pick up an early deposit) yields a new config id with an empty cursor; the indexer re-ingests the same finalized Staked/Withdrawn events under the new id, settlement re-walks every completed day, inserts a second reward journal per (day, wallet) and the wallet's spendable GOLD doubles.

     Nothing in defineEconomyConfig, settleEconomy or the schema detects that the same chain events were already credited to the wallet. This violates REQUIREMENTS.md rules 3 and 7 (one GOLD per share-day; no path may mint arbitrary GOLD) through an ordinary operational configuration change rather than an attack.

     Prerequisite: an operator redeploys the Worker with a different deploymentBlock (or any config-id field) while keeping the same contracts; the economy-config.ts:42 comment shows only catalogue edits were considered. The existing tests never define two configs over the same contracts.

     Fix (preserves design): make the reward journal reference independent of deploymentBlock (e.g. chainId:stakingContract:day:wallet) or add a UNIQUE guard per (wallet, day) for utc-reward journals and treat a conflict as already credited, and/or have defineEconomyConfig refuse a stakingContract that already has economy_chain_state rows under a different config id.

     A payment with a different amount is therefore indexed as an event that matches no order, the order stays 'pending', the tokens sit in the treasury with no refund entry point (contracts are ownerless and immutable by design), and a second call with the correct amount from the same wallet reverts OrderAlreadyPaid.

     Prerequisite: the payer calls pay() directly (block explorer, script, wallet that lets the user edit calldata, or a third-party/buggy client) with an amount other than order.amount; the shipped EconomyPane/EconomyWalletController always encodes the exact server amount and checks paid() before prompting (economyWallet.ts:110,140), and the mapping is per payer so no third party can block another wallet's order.

     It still means the rule-11 promise that 'a successful exact EMBEO payment is reconciled from its finalized receipt' becomes impossible for that order after one mistake, and nothing server-side flags the stranded tokens.

     Design-preserving mitigation: key the replay guard on (payer, keccak256(orderId, amount)) so the exact payment remains possible while exact replays stay blocked (server matching already requires wallet+orderId+amount and paid_event_id is UNIQUE, so no double fulfilment), and/or record indexed payment events whose (wallet, orderId) match a pending order with a different amount so operators can reconcile.

     Merged from audit_permissions, audit_economics and audit_flow (identical mechanism); reproduced by Foundry test in a scratch project (see reproduction).

     whole finding

     Deploy AdversarialToken (contracts/test/AdversarialToken.sol, plain 18-decimal fixed-supply token) and EmbeoPayments(token, treasury).

     Server order X quotes amount 1e18 for payer W.

     W approves 2e18 and calls pay(X, 1): succeeds, Paid(X, W, token, treasury, 1) is emitted, treasury balance +1 wei, paid(W, X) == true.

     Indexer: event amount '1' != order amount '1000000000000000000', so economy_orders stays 'pending' and no economy_fulfillments row is written.

     W then calls pay(X, 1e18).

     Expected (rule 11): the exact payment can still be made and reconciled.

     Actual: revert OrderAlreadyPaid(); order X can never be fulfilled by W and the 1 wei is not refundable (no admin/rescue function exists).

     Scratch forge test run on this tree: forge test on a test that expects the second pay(X,1e18) to succeed fails with OrderAlreadyPaid().

   • infoIdempotent order replay returns an expired pending quote rather than ORDER_EXPIREDworld-source/server/economy-ledger.ts:197

     createEconomyOrder returns the previously stored order for the same (wallet, requestId) without checking expires_ms.

     EconomyPane keeps orderAttempt (same requestId) for the same service/currency until the order is paid or renewOrder clears it, so a client that re-selects the same service later receives a pending order whose expiresMs is already past; the following GOLD challenge request then fails with ORDER_EXPIRED, and an EMBEO plan fails client-side with INVALID_ORDER (economyWallet.ts:101).

     No funds are at risk: an expired EMBEO quote is immutable and a late exact Paid event still fulfils it, and GOLD challenges cannot be issued on an expired order. The pane recovers through its expired-order notice and renewOrder. Returning ORDER_EXPIRED (or a fresh quote) on replay of an expired pending order would remove the timestamp-detection burden from clients.

     From audit_economics; reproduced here.

     whole finding

     createEconomyOrder(db,config,{wallet:W,requestId:'q'.repeat(20),serviceId:'svc',currency:'EMBEO',nowMs:D0}) then the same call with nowMs:D0+86400000.

     Expected: ORDER_EXPIRED conflict or a fresh quote.

     Actual (script output on this tree): 'same id true status pending expiresMs<nowMs true', i.e. the same order id is returned with status pending and expiresMs (D0+900000) < nowMs.

   • infoTrust assumption: immutable supply and code-hash binding turns any EMBEO supply/runtime change into permanent loss of withdrawals; mainnet runtime readback was not performed in this reviewcontracts/src/ExactEmbeo.sol:32

     Not a bypass. Every deposit, pay and withdraw first requires the token's current codehash and totalSupply to equal the values captured at construction. If mainnet EMBEO ever differs from the public fixture (contracts/fixtures/embeo-token-artifact.json: fixed-supply ERC-20 with no mint/burn/pause/proxy), a single supply change would make withdraw() revert forever and lock all principal, contradicting 'durable halt must not confiscate principal' at the contract layer.

     The binding is the requested token-identity check and should stay; the release gate must run contracts/tools/preflight.mjs against mainnet (runtime hash, decimals, totalSupply 1e27) and record the readback. This review made no mainnet RPC call, so the deployed token runtime, vault/payment immutables and deployment readback remain unverified release blockers. From audit_permissions.

     State: any vault with staked principal.

     Input: token.totalSupply() returns a value different from the immutable tokenSupply (AdversarialToken.changeSupply() in contracts/test/AdversarialToken.sol, or a real token exposing burn()/an upgraded proxy).

     Call withdraw(positionId, 1).

     Expected per REQUIREMENTS rule 5: principal is refundable at any time.

     Actual: revert TokenChanged() on every call, permanently.

     Local control: contracts/test/contracts.test.mjs already exercises TokenChanged with the AdversarialToken; the open item is the mainnet readback, which was not executed here.
