# Audit report > Audit this expanded Ember World shared GOLD candidate at public commit d0a6f42c1e455f16472ea0c51c310f7f2710a9fd (selected projection of local source 57ce2d598eedf2ded2a2080582efcd29b4214adb). Review TypeScript, SQL and Python as well as the retained Solidity boundaries. Start with README.md, SCOPE.md, REQUIREMENTS.md, LOCAL_TESTS.md, the manifests and context/publication-projection.json. This is a selected source export, not a complete World artwork/web build. Check the implementation and reproducible tests; prior test results are evidence, not a substitute for your independent review. > > Highest-priority checks: > 1. EMBEO purchases of GOLD are one-way point topups, never an AMM or trading pair. GOLD is wallet-bound, cannot transfer to another wallet, cannot redeem/sell for EMBEO, and has no cash-out. Topup income goes to the existing confirmed treasury; staking principal must never fund purchases, service fees or administrator operations. Check immutable original-price/version orders, exact integer arithmetic and 18-decimal UI handling, canonical/finalized payment evidence, wrong payer/token/chain/amount, replay, concurrent confirmation and bounded partial-credit repair. Automatic reconciliation and admin repair together must credit only the original remaining entitlement once. Changed prices affect new orders, not a valid old order's locked price. > 2. One persistent GOLD book/available/held account must serve legacy payments, topups, staking, service jobs and R4 Mint. Available = book minus held; no legacy route or concurrent consumer may spend held funds. Check transaction/CAS boundaries, duplicate source/order/receipt keys, reservation ownership and chain/contract/chain-instance scope. A timeout, UI close, process restart or restored SQLite file must not by itself authorize release of a pending Mint hold. Settle/consume or cancel using proven chain outcomes. Test cross-consumer double spending, retries, rollback and partial writes. > 3. World authentication must authorize the current wallet and live session, including EOA/SIWE continuity, same-origin request checks and revalidation after asynchronous work and within SQL mutations. Check logout, wallet switch, expired/stale sessions, concurrent requests and expected-address mismatch. The three confirmed owner wallets do not grant ordinary players owner rights. Admin repair must be bounded by an evidenced entitlement; there must be no arbitrary balance setter or unlimited grant. Verify immutable actor/request/reason and atomic before/after evidence, duplicate repair prevention, and price/trial/pause control authorization. > 4. Paid service debit creates one durable delivery job. Verify attempt/lease fencing, saved result retrieval without a second charge, retry and recovery. Unknown provider timeout is not proven terminal nondelivery. Refund the original GOLD at most once only on the supported terminal-failure path. Late completion must not overwrite a refunded state, expose a result improperly, or trigger another debit/refund. Exercise debit/job creation atomicity, lease expiry, stale workers, refund/finish races and repeated callbacks. > 5. Historical staking correction must not mistake purchased GOLD, refunds or other non-staking sources for missed staking rewards. Preserve old finalized evidence; include the new sources and holds in reconciliation/restore invariants and atomic guards. Feature pause stops new admissions while valid pending payments/reconciliation, saved results, lawful refunds and principal withdrawals remain serviceable. Do not infer pending transaction failure from elapsed time alone. > 6. Staking remains positive multiples of 100000 EMBEO, with 1 GOLD per unit for each completed UTC calendar day after next-day finalized confirmation. Principal is withdrawable at any time; only the withdrawn units lose that day's yield. Preserve valid other-unit/other-day rewards. No rolling 24-hour or per-second replacement, burn or revenue sharing is intended. Existing staking/payment Solidity and R4 Mint Solidity are unchanged; verify their exact retained boundaries, adapters and projections rather than limiting this audit to Solidity. > 7. Free and paid R4 Mint open simultaneously, first successfully completed wins from one shared supply of 2222. One free Mint per eligible Active Agent wallet, with neither EMBEO nor GOLD fee, no three-day window and no reserved free pool. Paid Mint still needs both its EMBEO fee and GOLD; buying GOLD does not offset the EMBEO Mint fee. Check that the copied service awaits the shared persistent reservation/settlement ledger and cannot bypass it through a legacy/test path. > 8. AIMarket trial controls use authenticated World research sessions only. Check UTC half-open start/end boundaries, manual stop, claim/introspection authenticity and fresh rechecks in World and its Python consumer. Trial claims must not unlock direct external-site visitors or elevate a player to owner, and must not require a second research-login signature. Review privacy and consistency at this boundary. > > Reproduction and limits: LOCAL_TESTS.md distinguishes full-workspace tests from portable reproduction. The full workspace recorded 2804 passes, zero failures and five pre-existing Windows symlink skips; the selected financial suite, contracts and Python tests are reported separately. Local EDR, synthetic sessions, fixture providers/prices and local exact-production-SQL workerd D1 are fixtures, not proof of mainnet runtime/finality, real-wallet behavior, actual external AIMarket/fortune delivery, target VPS installation or production Workers CPU/D1 capacity. SQLite restore does not restore the memory-only EDR chain. The production Worker economy configuration still returns null. Fixture prices are not launch prices. Game development/reward issuance and production NFT/collection rights are deferred and are not delivered by this packet. > > Please report concrete exploit/failure paths, affected files/lines, severity, assumptions and actionable regression tests. Include negative controls and assess the cross-language/state-machine boundaries. Distinguish demonstrated implementation vulnerabilities from unresolved deployment-specific release gates; neither local fixture success nor absence of findings authorizes deployment. No paid audit submission, wallet signature, payment, deployment or production migration is authorized by preparation of this packet.

Nothing in the repository was changed or deployed. ## Findings ### 1. Medium: AIMarket consumer raises BridgeUnavailable instead of treating an ended trial as inactive, denying EMBEO holders at the campaign end boundary `aimarket/web/world_auth.py:249` ``` or (trial["active"] and (trial["endsMs"] is None or trial["endsMs"] <= _now_ms()))): ``` World computes world_trial.active with its own clock when it answers /api/aimarket-auth/session (server/aimarket-auth.ts:151 -> goldCampaign, half-open now=1, key set) as hard failures, but when active is True and endsMs <= _now_ms() normalise the trial to inactive (or simply let _world_trial's existing now ('0xaaaa..aa', True); active=False with endsMs=NOW-20 -> ('0xaaaa..aa', True). ### 2. Medium: Historical recovery planner and preflight crash with an unhandled TypeError on any database that has not applied migration 0014 `world-source/server/economy-recovery.ts:204` ``` const totals=new Map();for(const j of [...journal,...at(old,'world_gold_entries')])totals.set(j.wallet!,(totals.get(j.wallet!)??0n)+BigInt(j.delta!)); ``` snapshots() (lines 40-44) deliberately tolerates a pre-0014 database: when none of the world_gold_* tables exist it skips them and continues, which is the state of the deployed World D1 today and of any controlled pre-0013/0014 export. But build() later calls at(old,'world_gold_entries') unconditionally on this line, and at() (line 45) does s.find(...)!.rows, so with the snapshot absent the planner throws "TypeError: Cannot read properties of undefined (reading 'rows')" instead of returning a plan or a reviewed RECOVERY_* refusal. preflightEconomyRecovery (line 264) catches only RecoveryCapacityError, so the read-only diagnostic crashes identically. The staking-correction workflow (requirement 5) is therefore unusable on exactly the schema it must currently run against, and an operator cannot distinguish a schema gap from a planner bug. Every existing recovery test opens the database with all migrations, so this path is untested. Fix: treat a missing world_gold_entries snapshot as an empty row set (or return fail('RECOVERY_SCHEMA_MISSING') explicitly, matching the intent of snapshots()), and add a test that runs prepareEconomyRecovery and preflightEconomyRecovery on openD1(migrationFiles().filter(f=>!f.startsWith('0014'))). **Reproduction** Reproduced with test/scratch/repro.mjs case pre0014_recovery: two in-memory D1 adapters opened with migrationFiles().filter(f=>!f.startsWith('0014')); original DB gets economy_chain_state(config.id,last_block=102,last_hash=hash(102),through_ms=NOW+2d); shadow DB gets the same row for a successor config (deploymentBlock '99'); no events. prepareEconomyRecovery(db,shadow,from,to,{nowMs:through+1}) -> expected a plan with zero adjustments or a RECOVERY_* coded refusal; actual: TypeError: Cannot read properties of undefined (reading 'rows'). preflightEconomyRecovery with the same inputs -> expected {status:'ready'|'blocked'}; actual: the same TypeError. Negative control: the packaged test 'historical staking recovery preserves purchased GOLD and holds' passes with all migrations applied. ### 3. Low: Pausing the service feature does not stop GOLD debits and job admissions for quotes issued before the pause `world-source/server/economy-ledger.ts:277` ``` bind(db,`INSERT INTO economy_gold_journal(id,wallet,delta,kind,reference,created_ms) SELECT ?,?,-CAST(? AS INTEGER),'service-payment',?,? WHERE EXISTS(SELECT 1 FROM economy_orders WHERE id=? AND wallet=? AND status='pending' AND expires_ms>?) AND EXISTS(SELECT 1 FROM economy_gold_challenges WHERE order_id=? AND request_id=? AND nonce=? AND consumed_ms IS NULL AND expires_ms>?) AND ${auth.sql} AND NOT EXISTS(SELECT 1 FROM economy_chain_state WHERE config_id=? AND halted_reason IS NOT NULL)`,reference,wallet,existing.amount,reference,now,id,wallet,now,id,args.requestId,challenge.nonce,now,...auth.values,config.id), ``` world_gold_controls is consulted only when a quote is created (world-gold.ts goldQuote: goldFeature() plus the in-batch check on line 44). A quote stays payable for 15 minutes (expires_ms = now+900000). payEconomyOrderGold, the only path that debits GOLD for a World service order, and createEconomyGoldChallenge never read world_gold_controls, and reconcileWorldGold (cron, or POST /api/gold/orders/:id/reconcile by the player) then creates the queued delivery job. So after an owner pauses 'service', a quote obtained earlier still yields a new challenge, a book debit, a paid order and a queued job. REQUIREMENTS.md says a pause stops new admissions while already finalized work stays serviceable; an unsigned, undebited quote is not yet an admission and, unlike an on-chain EMBEO topup, can be refused server-side at no loss to the player. Fix: when the order has a world_gold_links row of kind 'service', add AND EXISTS(SELECT 1 FROM world_gold_controls WHERE feature='service' AND enabled=1) to this journal INSERT predicate (and refuse challenge creation while paused); leave reconcile, delivery and refunds of already-paid orders unaffected. Regression test: quote, pause, pay -> expect FEATURE_PAUSED, no journal row, order still pending; re-enable -> the same order pays exactly once. **Reproduction** Reproduced with test/scratch/repro.mjs case pause_service_bypass using the world-gold.test.mjs fixture shape: topup (book 10); id=goldQuote('research'); goldAdminCommand control service enabled:false version:0; negative control goldQuote('research') now rejects FEATURE_PAUSED; then createEconomyGoldChallenge + payEconomyOrderGold with a valid EOA signature for id, then reconcileWorldGold(db,NOW). Expected: payment rejected, book stays 10, no world_gold_jobs row. Actual: no error, book 7, world_gold_jobs has one row state 'queued' for id while world_gold_controls shows service enabled=0 version=1. ### 4. Low: An oversized provider result leaves a paid service job permanently non-terminal: never delivered, never failed, never refundable `world-source/server/world-gold.ts:80` ``` at(args.nowMs);const json=JSON.stringify('result' in args.outcome?args.outcome.result:null);if(json.length>16000)fail('RESULT_TOO_LARGE'); ``` finishGoldJob rejects a successful delivery whose serialized result exceeds 16000 characters before touching the row. The job stays 'working' until its 60 s lease lapses, claimGoldJob (line 76) hands it to the next worker, the adapter (which must reuse orderId as idempotency key) fetches the same result and fails again. The job can never reach 'delivered'; because it never reaches 'failed', neither refundGold (line 70, REFUND_NOT_ENTITLED) nor the admin refund-service command (line 139 requires state IN ('failed','refunded')) can return the GOLD. The player is debited, has no result, and there is no bounded operator path. A size cap is reasonable, but a result that cannot be stored must become a terminal outcome (store by reference, truncate with a marker, or record a provider failure so the once-only refund applies). Only fixture adapters exist today, so this is a boundary defect a real provider adapter would hit. **Reproduction** Reproduced with test/scratch/repro.mjs case oversized_result: topup (book 10), paid research order (book 7), a=claimGoldJob(id,NOW); finishGoldJob({orderId:id,attempt:a,nowMs:NOW+1,outcome:{result:'x'.repeat(16001)}}) rejects RESULT_TOO_LARGE and the row stays state 'working'; refundGold(id,NOW+2) rejects REFUND_NOT_ENTITLED; admin refund-service rejects; claimGoldJob(id,NOW+3) returns null; claimGoldJob(id,NOW+60001) returns a new attempt and the same finish fails again, state 'working', book 7. Expected: a terminal state with the 3 GOLD refundable exactly once or the result retrievable. Negative control in the same case: finishGoldJob with outcome {failure:'provider-confirmed'} on the live attempt moves the job to 'refunded' and book back to 10. ### 5. Low: One int64-overflowing topup credit aborts the whole global reconciliation batch forever; the admin product cap of 2^63-1 makes it constructible `world-source/server/world-gold.ts:63` ``` if(statements.length)await db.batch(statements); ``` reconcileWorldGold selects up to 128 pending paid topups ordered by created_ms and executes every credit() INSERT in one db.batch (one SQLite transaction). If any single INSERT fails, all other wallets' credits roll back, and because the failing order stays pending and oldest it is selected on every later run, so the scheduled path (worker/app.ts:155) never credits anyone again. A failing credit is reachable through the published limit: goldAdminCommand accepts product gold up to ECONOMY_MAX_INTEGER (line 129, 9223372036854775807). After one such credit the wallet balance is 2^63-1; the next topup for that wallet makes trigger world_gold_entry_apply compute balance+delta, which SQLite promotes to REAL, and economy_gold_accounts CHECK(typeof(balance)='integer') aborts the transaction. Products, links and orders are immutable, so the admin cannot cancel the poisoned order, and repair-topup fails with the same CHECK. Per-order reconcile still works, so no GOLD is lost, but automatic reconciliation and the admin repair path for everyone else stay broken. This needs an admin pricing mistake (a documented power, see the trust-assumption note), so severity is low. Fix: cap product gold far below int64 (e.g. 10^15) in goldAdminCommand and the products CHECK, and commit reconcile credits per order (or catch and skip a failing order and log it) so one order cannot block the others. **Reproduction** Reproduced with test/scratch/repro.mjs case int64_poison: admin products 'pack' gold=10 and 'huge' gold='9223372036854775807' embeo='1' (both accepted). Wallet B: quote 'huge', pay, reconcileWorldGold -> B.book='9223372036854775807'. Wallet B: second 'huge' quote, pay. Wallet A: quote 'pack', pay. reconcileWorldGold(db,NOW+10) -> expected A credited 10 with B's order left pending; actual: throws "CHECK constraint failed: typeof(balance)='integer' AND balance>=0" and A.book stays 0. reconcileWorldGold(db,NOW+11,aOrderId) -> A.book=10 (negative control). A second global reconcile throws again; goldAdminCommand repair-topup for B's second order throws the same CHECK error. ### 6. Low: settleMintGold releases a held Mint reservation before its stored deadline on any non-empty evidence object; the ledger never checks the proven chain outcome itself `world-source/server/world-gold.ts:105` ``` if(!o.evidence||!Object.keys(o.evidence).length)fail('MINT_EVIDENCE_REQUIRED'); ``` Requirement 2: a timeout, UI close, restart or restored file must not by itself authorize release of a pending Mint hold; settle or cancel on proven chain outcomes. In the shared persistent ledger that rule exists only in the fixture adapter (scripts/world-gold-local-runtime.mjs:31 refuses release while used||(!revoked&&chainTime<=deadline)). settleMintGold stores deadline in world_gold_mints but never reads it; the only evidence check is Object.keys(o.evidence).length>0, and trigger world_gold_mint_update (migrations/0014:77-80) only requires evidence_json IS NOT NULL. Any server caller (a future production adapter, a maintenance script, a retry handler that treats an RPC timeout as 'released') can release a hold whose signed PaidAuthorization is still executable on chain. Once released the player's available GOLD rises and can be spent elsewhere; when the on-chain paid Mint later executes within order.deadline, the consume path fails MINT_STATE_CONFLICT and the Mint completes with its GOLD cost never debited (cross-consumer double spend). No HTTP route reaches settleMintGold and the shipped adapter is correct, so this is a missing defence at the boundary the production adapter is said to await. Fix: for state 'released' require nowMs>row.deadline or an evidence shape the ledger can verify (e.g. evidence.revoked===true with a block hash), and mirror the deadline rule in the world_gold_mint_update trigger; keep 'consumed' unchanged. **Reproduction** Reproduced with test/scratch/repro.mjs case early_release: fresh DB after all migrations, topup product gold=10, wallet A pays and reconciles (book 10). reserveMintGold(db,{id,wallet:A,auth:{x:1},gold:'8',chainId:1,contract,chainInstance:'run-1',deadline:NOW+300000},NOW) -> snapshot [book,reserved,available]=['10','8','2']. settleMintGold(db,{id,chainId:1,contract,chainInstance:'run-1',state:'released',evidence:{timeout:true}},NOW+1). Expected: rejected (NOW+1 < deadline and nothing proves revocation). Actual: succeeds; snapshot ['10','0','10']. A research service is then paid from the freed GOLD (book 7). settleMintGold(...state:'consumed',evidence:{tx}) for the on-chain execution of the same authorization throws MINT_STATE_CONFLICT with book still 7: the 8 GOLD is never debited. Negative control: the packaged test 'different private chain instance and empty outcome cannot release' passes, and the fixture adapter release() throws MINT_AUTH_EXECUTABLE in the same state. ### 7. Low: A pending Mint hold whose chain instance or in-memory order map is gone can never be consumed or released; no evidenced operator or reconciliation path exists `world-source/server/world-gold.ts:103` ``` if(!row||row.chain_id!==o.chainId||row.contract!==economyAddress(o.contract)||row.chain_instance!==o.chainInstance)fail('MINT_SCOPE_MISMATCH'); ``` Holds are scoped to (chain_id, contract, chain_instance). The local EDR instance id (mint.runId) is regenerated on every process start or reset, and mint.orders, which the adapter's consume()/release() require, is memory-only; reconcileOrders (mint/service/chain.mjs:131) iterates only that map. After a restart, a SQLite restore or a reset, every 'held' row of the previous instance is unreachable: settleMintGold rejects both 'consumed' and 'released' with MINT_SCOPE_MISMATCH, no admin action (product/campaign/control/repair-topup/refund-service) can touch world_gold_holds, and worldGoldSnapshot subtracts the amount from available forever. Not releasing on restart alone is correct; the gap is that the packet provides no bounded, evidenced path at all (for example an admin or reconciliation step over world_gold_mints WHERE state='held' that settles from stored scope plus chain reads of paidOrderTokenId / paidOrderRevoked / block.timestamp > deadline, recorded with before/after state). In production the Worker contains no Mint settlement component, so the same orphaned state arises whenever the external Mint service is redeployed with a new instance id. Liveness/operability gap, not theft: available never goes negative and no GOLD is created. Merged from audit_economics (REPRO-2) and audit_permissions (runtime reopen) reports of the same gap. **Reproduction** Reproduced with test/scratch/repro.mjs case orphan_hold: topup (book 10); reserveMintGold with chainInstance 'edr-run-1', gold 8, deadline NOW+300s -> 10/8/2. Simulated restart: settleMintGold with chainInstance 'edr-run-2' at NOW+1e9 (deadline long past) for state 'released' and 'consumed' -> both fail MINT_SCOPE_MISMATCH; admin repair-topup and refund-service on the mint id fail their predicate check (CHECK constraint failed: accepted=1); worldGoldSnapshot at NOW+1e9 still shows ['10','8','2']. Also confirmed on the real EDR runtime (test/scratch/reset.mjs): after mint.admin({action:'reset'}) mint.orders.size is 0 and runId changed, so the injected release(id) throws MINT_ORDER_MISSING and the hold stays 'held' with available reduced by 1. ### 8. Low: Copied Mint service resetChain() silently replaces the injected shared persistent GOLD ledger with the in-memory fixture ledger and strands existing holds `mint/service/chain.mjs:33` ``` this.gold=new LocalGoldLedger();this.orders=new Map();this.records=[];this.receipts=[];this.packets=new Map();this.submissions=new Set(); ``` SCOPE.md and REQUIREMENTS.md require the copied R4 Mint service to await the injected shared persistent ledger and not bypass it through a legacy/test path. Injection is instance assignment after construction (world-source/scripts/world-gold-local-runtime.mjs:23 mint.gold={view,reserve,consume,release}), but resetChain() unconditionally re-creates this.gold=new LocalGoldLedger() and clears this.orders, and admin({action:'reset'}) (line 166) calls it. The world-gold preview blocks that action only at its HTTP layer (scripts/world-gold-preview.mjs:30 LOCAL_ACTION_FORBIDDEN); the standalone mint server (mint/service/server.mjs /api/admin) and any in-process caller can still trigger it. After one reset the paid-Mint path reserves from the fixture balances (A=10,B=10) with no world_gold_holds row, while mint.beforeApproval (feature pause) still fires, so the pause survives but the money path does not; every hold that was 'held' before the reset is orphaned because mint.orders is empty and runId (chain_instance) changed. Expected: a service that received a shared ledger keeps it across reset or refuses reset. Fix: in resetChain() preserve an injected ledger (only construct LocalGoldLedger when this.gold is unset or is itself a LocalGoldLedger) and refuse 'reset' while shared holds are outstanding, instead of relying on one caller's route filter. **Reproduction** Reproduced with test/scratch/reset.mjs on the real EDR runtime (cwd repo root, contracts and world-source dependencies installed): r=await createGoldLocalRuntime(); wallet A quotes and pays 'gold-pack' (shared book 10). r.mint.gold.reserve(id,'A',1n,{auth:{wallet:A,deadline,orderId:id},packet:{}}) -> one world_gold_holds row 'held'. Negative control: the same reserve for wallet C (no GOLD) rejects. await r.mint.admin({action:'reset'}) -> r.mint.gold instanceof LocalGoldLedger is true, r.mint.orders.size is 0, runId changed. r.mint.gold.reserve(id4,'A',1n) succeeds against the fixture ledger (fixture view A book 10 reserved 1) while world_gold_holds still has only the original held row; mint.state() reports wallets' gold from the fixture ledger (B book 10 although B never bought GOLD). The shared snapshot for A stays [10,1,9] permanently because the original hold can no longer be settled. ### 9. Low: Paid service GOLD debit and delivery-job creation are not one transaction, and the scheduled job/refund pass is gated behind chain RPC sync succeeding `world-source/worker/app.ts:155` ``` await reconcileWorldGold(env.DB,at); ``` Requirement 4 says a paid service debit creates one durable delivery job. payEconomyOrderGold (economy-ledger.ts:276-280) commits the journal debit, paid status and consumed challenge in one batch that contains no world_gold_jobs insert; the job is derived later by reconcileWorldGold (world-gold.ts:61), which the browser calls after payment or the Worker cron calls here. In syncEconomy the call is sequential after await syncEconomyChain (line 154) with no separate try/catch, and only when economy.config() is non-null and ECONOMY_CHAIN_LIMITER is bound; the scheduled() handler swallows any throw of the whole syncEconomy promise. So any chain-sync failure (ECONOMY_RPC_RATE_LIMITED from the limiter wrapper on line 151, an RPC outage, a halted economy) skips GOLD job creation and the 'failed'->'refunded' pass for that run, although neither needs chain data. Until the player manually posts /api/gold/orders/:id/reconcile, a debited service order has no job and a provider-confirmed failure stays unrefunded, precisely during the RPC incidents when degradation is likely. No GOLD is lost (the paid order is immutable, reconcile is idempotent), so this is a liveness and specification-conformance defect. Fix: insert the world_gold_jobs row in the payEconomyOrderGold batch (INSERT..SELECT guarded by a world_gold_links row of kind 'service', when the shared tables exist), and run reconcileWorldGold independently of syncEconomyChain (own try/catch, regardless of chain sync outcome). Merged from audit_flow (cron gating) and audit_math/audit_economics (atomicity) reports. **Reproduction** Atomicity reproduced with test/scratch/repro.mjs case job_not_atomic: fresh DB, research product gold=3, wallet book 10; goldQuote('research'), createEconomyGoldChallenge + payEconomyOrderGold with a valid signature -> economy_orders.status='paid', yet SELECT COUNT(*) FROM world_gold_jobs WHERE order_id=? returns 0 until reconcileWorldGold runs (then 1, state 'queued'). Cron gating verified in code: worker/app.ts:146-156 awaits syncEconomyChain on line 154 before reconcileWorldGold on line 155 inside one async function whose rejection is caught only at scheduled() line 195; a throw from the rpc wrapper (line 151, ECONOMY_RPC_RATE_LIMITED) or from syncEconomyChain therefore prevents line 155 from executing. Expected: the job row exists when payEconomyOrderGold returns, and reconcile/refund run even when chain sync fails. ### 10. Info: world_gold_write_checks grows by one permanent row per quote predicate, reservation and admin command with no pruning `world-source/server/world-gold.ts:8` ``` const check=(db:D1Database,predicate:string,...args:unknown[])=>st(db,`INSERT INTO world_gold_write_checks(id,accepted) SELECT ?,CASE WHEN ${predicate} THEN 1 ELSE 0 END`,crypto.randomUUID(),...args); ``` The CAS-in-SQL pattern records every accepted predicate as a row keyed by a fresh UUID. Only admin actions need their before_json row kept (the audit insert on line 125 joins it); quote and reserve check rows are never read again, yet nothing deletes them and the scheduled housekeeping in worker/app.ts does not touch the table. On D1 this is unbounded row growth driven by any authenticated player (two rows per /api/gold/quote, bounded only by the per-IP ECONOMY_LIMITER), and the recovery planner snapshots the whole table into every plan (TABLES includes WORLD_GOLD_TABLES), so growth also pushes recovery toward RECOVERY_REQUIRES_LARGER_REVIEWED_PLAN. Fix: prune rows with before_json IS NULL in the cron (or use a rollback-only predicate such as a trigger-raised scratch insert deleted in the same batch), and exclude non-audit rows from the recovery snapshot. **Reproduction** Reproduced with test/scratch/repro.mjs case write_checks: after setup with one admin product the table has 3 rows; 20 goldQuote calls by one wallet add 40 rows (one auth check plus one product/control check each), none removed afterwards (43 rows). Expected: bounded storage or rows scoped to the audit trail only. Actual: linear growth with player quotes. ### 11. Info: Deployed Worker creates queued service jobs but contains no claim/finish consumer, so production paid service orders would have neither delivery nor a lawful refund path `world-source/worker/app.ts:155` ``` await reconcileWorldGold(env.DB,at); ``` The minute cron only calls reconcileWorldGold, which turns paid GOLD service orders into world_gold_jobs rows in state 'queued'. claimGoldJob/finishGoldJob are invoked only by the local fixture runtime (scripts/world-gold-local-runtime.mjs:42). Because a refund requires state 'failed', which only finishGoldJob can set, a player debited for research/fortune in production would have no delivery, no refund, and no admin remedy (refund-service requires state IN ('failed','refunded')). This is consistent with SCOPE.md (real providers are a release gate; the Worker economy config returns null), so it is a documented deployment gap rather than an implementation vulnerability. Release checklist items: a durable worker that claims jobs with orderId as the provider idempotency key; an explicit classification where only proven terminal nondelivery maps to {failure}; and a check that the 'service' feature cannot be enabled while no consumer is bound. **Reproduction** grep -rn 'claimGoldJob\|finishGoldJob' world-source/worker world-source/server returns only the definitions in server/world-gold.ts; no Worker code path calls them. State walk: with migration 0014 applied, a 'service' product enabled and a non-null economy config, a paid GOLD order reconciled by cron becomes world_gold_jobs state 'queued' and stays there; refundGold/refund-service then reject with REFUND_NOT_ENTITLED (requires state 'failed'), as the packaged test 'timeout does not refund' shows for the queued/working states. ### 12. Info: Trust assumptions bounding the permission model: admin product grants are unbounded in gold, the treasury wallet is also an administrator, and settlement facts are trusted from server callers `world-source/server/world-gold.ts:129` ``` const gold=economyUint(cmd.gold,ECONOMY_MAX_INTEGER),embeo=cmd.kind==='topup'?economyUint(cmd.embeo):null; ``` Documented powers, not bypasses. (1) The three admin wallets (server/aimarket-admin.ts:8-12) include the production treasury (economy-config.ts), so the payment receiver is also the price/pause/campaign administrator. (2) The 'product' action lets an admin publish a topup version with any embeo >= 1 wei and gold up to 2^63-1 on this line; through the self-serve quote route that is economically an unbounded GOLD grant to whoever buys at that version. It is versioned, immutable, audited and never alters a paid order's locked price, so it is a documented power rather than the forbidden arbitrary balance setter, but it is also the enabler of the int64 batch-poisoning finding. (3) settleMintGold (line 101) and finishGoldJob (line 79) trust their server caller for chain evidence and for the terminal-failure classification; the only callers in this packet are the local fixture adapter. (4) reserveMintGold performs no session check; wallet identity for Mint reservations is delegated to the Mint service, whose packet authentication is a loopback session token. Checked and found sound in this review: same-origin and Sec-Fetch-Site gating and Origin requirement on writes (world-gold-api.ts:30,33), expected_address matching, double readSession plus SQL-level session EXISTS inside quote/admin batches (authCheck), EOA/ECDSA requirement for writes, admin idempotency with payload comparison, version CAS on controls/products/campaigns, hold/available triggers covering legacy GOLD debits, once-only topup/refund references, half-open UTC campaign bounds in World, trial never unlocking the external profile, and the recovery planner's balance=journal+entries invariant. **Reproduction** Not an exploit path. Verification: goldAdminCommand(db,{wallet:OWNER,...,command:{action:'product',product:'huge',kind:'topup',title:'h',gold:'9223372036854775807',embeo:'1',enabled:true,version:1}}) succeeds (test/scratch/repro.mjs case int64_poison); grep -rn settleMintGold world-source/worker world-source/server returns only the definition; AIMARKET_ACTIVITY_ADMIN_WALLETS in server/aimarket-admin.ts lists the treasury address from server/economy-config.ts. --- Judge's submission `8ddc35ffcf9ca9167f1ac2a3584dadaff09e3dcad1325ee91c0f4f0ec6ae1557`, accepted on the IdentityMD network. Acceptance means the report met the job's checks; it is not a guarantee that the code has no other defects.
