Nothing in the repository was changed or deployed. ## Findings ### 1. Medium: Finalized withdrawal of a position staked before the pinned deploymentBlock stalls ingestion forever without a durable halt reason; the same block's exact EMBEO payment never fulfills and no payment c `world-source/server/economy-ledger.ts:69` ``` catch(error){if(await bind(db,'SELECT id FROM economy_ingestions WHERE id=?',ingestionId).first())return {replayed:true,eventCount:events.length};throw error;} ``` The migration 0010 trigger economy_event_withdraw (world-source/migrations/0010_world_economy.sql:79-84) RAISEs ECONOMY_INVALID_WITHDRAWAL when a withdraw event names a position for which this config has no economy_positions row. A position staked in a block below config.deploymentBlock is exactly such a row, and the new 0013 earlier-deploymentBlock recovery scope exists because that operator state is anticipated. EmbeoStakingVault.withdraw succeeds on-chain (the contract checks ownership itself), the finalized Withdrawn log is decoded by economy-rpc.ts and passed to ingestEconomyEvents, the whole block batch aborts, and the catch at line 69 rethrows the raw SQLite error. Nothing calls haltEconomyChain, so economy_chain_state.halted_reason stays NULL and every later synchronize() run rejects on the same block: a permanent, silent cursor stall. The design surfaces a changed finalized hash as a durable FINALIZED_REORG halt visible through chain.haltedReason, but this inconsistency is not surfaced at all: the pane only shows an ageing 'Chain data through' value, players keep being quoted EMBEO orders, and an exact-amount Paid event in the stalled block (or any later block) never completes its pending quote and never produces an economy_payment_cases row, so the immutable payment-facts guarantee fails for that payer. stageEconomyBlock's INSERT..SELECT fold (economy-staging.ts:54-55) fires the same trigger and stalls the same way. Prerequisite: operator pinned deploymentBlock above the real first stake, then any such early staker withdraws (fully or partially) after the pin. Fix: in ingestEconomyEvents/stageEconomyBlock detect ECONOMY_INVALID_WITHDRAWAL and call haltEconomyChain(db,config,'UNKNOWN_POSITION_WITHDRAWAL') so the state is durable, visible and recoverable via the 0013 path; or make the trigger tolerant of a withdraw for an unknown position (record the event without touching positions) so the block, cursor, payment fulfillment and payment case still commit. Merged from audit_permissions. **Reproduction** Node 24, world-source/ with node_modules installed: openD1() over all migrations, c=defineEconomyConfig({...deploymentBlock:'100'}). ingestEconomyEvents(db,c,{fromBlock:'100',toBlock:'101',toBlockHash:H(101),throughTimestamp:T+DAY,events:[stake(position 2, block 100, T)]}). order=createEconomyOrder(db,c,{currency:'EMBEO',...}). Then twice: ingestEconomyEvents(db,c,{fromBlock:'102',toBlock:'102',toBlockHash:H(102),throughTimestamp:T+DAY+1000,events:[withdraw(position 1, never staked in range, 1 share, block 102, logIndex 0), payment(order.id, exact 1e18, block 102, logIndex 1)]}). Expected: block 102 indexes (position 1 is a legitimate on-chain position) OR economyChainState().haltedReason is a durable code. Actual (observed): both attempts reject with 'Error: ECONOMY_INVALID_WITHDRAWAL'; economyChainState = {lastBlock:'101', haltedReason:null}; economy_orders.status for the order stays 'pending'; economyWalletSnapshot(db,c,W).paymentCases is empty. Probe output: 'attempt 0 error: Error: ECONOMY_INVALID_WITHDRAWAL / attempt 1 error: Error: ECONOMY_INVALID_WITHDRAWAL / state after { lastBlock: 101, haltedReason: null } / order status pending cases 0'. ### 2. Medium: Payment-case classification is per ingesting config but dedup is per payment contract: when another live config sharing the EmbeoPayments contract ingests first, the player's own fulfilling exact paym `world-source/server/economy-reconciliation.ts:22` ``` AND NOT EXISTS(SELECT 1 FROM economy_payment_cases p WHERE p.chain_id=r.chain_id AND p.payment_contract=r.payment_contract AND p.tx_hash=e.tx_hash AND p.log_index=e.log_index) ``` economyPaymentEvidenceStatement writes one immutable economy_payment_cases row per physical Paid log (UNIQUE(chain_id,payment_contract,tx_hash,log_index) in migrations/0013_economy_reconciliation.sql:59, plus the NOT EXISTS guard at line 22), but the classification CASE at lines 16-19 is evaluated from the perspective of whichever config's ingestion commits first. defineEconomyConfig (economy-config.ts:33) permits two live configs that differ only in stakingContract while sharing chain/token/paymentContract/treasury; this is exactly the 'another legitimate vault' shape the objective asks to exercise and that tests/economy-reconciliation.test.mjs:43 uses (`separate`). Both indexers filter eth_getLogs on their own staking plus the shared payment address, so both ingest the same Paid log. If the config that does not own the order (no lineage link) ingests the block first, line 17 classifies the payment 'wrong-config' and inserts the only row. When the owning config ingests, its UPDATE economy_orders fulfills the quote correctly, but the evidence INSERT is skipped by the dedup, so the sole immutable record of a fully successful payment says 'wrong-config'. Triggers economy_payment_case_no_change/no_delete make it permanent; reconcileEconomyPayments uses the same NOT EXISTS and cannot repair it; recordEconomyPaymentDisposition can only append and will accept 'acknowledged-no-entitlement' for a payment that did deliver the service. economyPaymentCases returns it (classification<>'matched') with correctPaymentEvent pointing at the owning config's event id, so the payer's pane lists their own fulfilling payment under payment reconciliation as 'Disposition pending', and the operator case export counts it as an unreviewed exception. The outcome depends on cron/isolate ordering between the two configs' sync flights, so the evidence table is nondeterministic. No funds move and fulfillment stays exactly-once; this is an integrity defect of the new immutable reconciliation evidence. Fix: classify against the physical event rather than the ingesting namespace (treat as 'matched' when the order owned by any config is fulfilled by this tx_hash:log_index), or let only the order-owning config or its lineage write the case for an order it owns, or reject configs that share a paymentContract in defineEconomyConfig. Merged from audit_permissions, audit_flow and audit_economics (three reports of the same mechanism at lines 17/22). **Reproduction** Node 24, world-source/: openD1(); X=defineEconomyConfig({stakingContract:0x11..11,paymentContract:0x22..22,deploymentBlock:'100',...}); Y=same but stakingContract 0x44..44. order=createEconomyOrder(db,X,{wallet:W,requestId:'order-under-x-0000001',serviceId:'svc',currency:'EMBEO',nowMs:T+DAY}). e={kind:'payment',transactionHash:0x..0bcc,logIndex:0,blockNumber:'102',blockHash:H(102),timestamp:T+DAY+1000,wallet:W,orderId:order.id,amount:'1000000000000000000',token:EMBEO,receiver:TREASURY}. ingestEconomyEvents(db,Y,{fromBlock:'100',toBlock:'102',toBlockHash:H(102),throughTimestamp:T+DAY+1000,events:[e]}) then ingestEconomyEvents(db,X,{same batch}). Expected: order paid under X and no non-matched payment case for W (or a 'matched' row). Actual (observed): economy_orders.status='paid', paid_event_id=':0x..0bcc:0', one fulfillment row, but economy_payment_cases holds exactly one row with config_id=, event_id=':0x..0bcc:0', classification='wrong-config'; economyWalletSnapshot(db,X,W).paymentCases=[{classification:'wrong-config',expectedAmount:'1000000000000000000',actualAmount:'1000000000000000000',correctPaymentEvent:':0x..0bcc:0',disposition:'unreviewed'}]; reconcileEconomyPayments(db,X) returns {remaining:0} and leaves the row 'wrong-config'. Reversing the order (X ingests first) yields one 'matched' row and an empty player case list, demonstrating order dependence. ### 3. Info: Dead ternary in ingestion ordering loop: both arms assign e.logIndex, so previousLog is never reset at a block boundary `world-source/server/economy-ledger.ts:47` ``` previousLog=block===previousBlock?e.logIndex:e.logIndex;previousBlock=block;previousTime=e.timestamp;previousHash=e.blockHash; ``` Both arms of the conditional assign the same value, so the expression equals previousLog=e.logIndex. The evident intent was to reset the per-block log cursor when the block number changes. No ordering or money defect follows: the only consumer is the guard on line 45, which compares logIndex against previousLog only under block===previousBlock, so a stale value carried across a block boundary is never read. Readability/intent note only. Fix: write previousLog=e.logIndex, or reset to -1 on a new block to match the intent. From audit_math; confirmed by reading and by exercising the guard. **Reproduction** Input: ingestEconomyEvents with events (block 100, logIndex 7) then (block 101, logIndex 0). Expected: accepted. Actual: accepted. Input: (block 100, logIndex 7) then (block 100, logIndex 7). Expected: EVENT_ORDER_OR_RANGE. Actual: EVENT_ORDER_OR_RANGE. The ternary has no observable effect in either version. ### 4. Info: Unreachable upper time bound in recovery replay: time>horizon+DAY can never hold for an event that passed the build() validation `world-source/server/economy-recovery.ts:43` ``` if(timehorizon+DAY||seen.has(identity))return fail('RECOVERY_EVENT_CONFLICT');priorTime=time;seen.add(identity); ``` horizon is Math.floor(clock(a.through_ms)/DAY)*DAY (line 75), so through_msthrough_ms with the horizon passed explicitly. From audit_math; confirmed by reading. **Reproduction** State: original DB through_ms=T, rebuilt DB through_ms=T. Any event with at_ms>T is rejected at line 87 (RECOVERY_EVENT_CONFLICT) before replay() runs; any event with at_ms<=T satisfies at_mshorizon+DAY. The fixture tests (tests/economy-reconciliation.test.mjs) and the earlier differential fuzz never hit this branch. --- Judge's submission `47a6a2add16ca9bc3fb1a17095355c0ce86bfaeb29bc9d176e833f9a443cf1e1`, 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.
