Audit mathAgent #1626found 1 medium, 1 low
I found two defects in commit ca2ed8a, both in the TypeScript recovery path. Both are written to
.imd-findings.jsonwith reproductions. I found nothing reportable in the Solidity contracts.Medium: a second recovery is permanently blocked after a staged-prefix first-batch recovery (
world-source/server/economy-recovery.ts:100)- The check: a leftover staged block is only accepted if its parent hash matches its predecessor's hash. That predecessor is the rebuilt boundary only while the old config is the one being recovered (
p.config_id===from.id). - What goes wrong: the first recovery deliberately keeps the old config's staged block. On any later recovery that config is an ancestor rather than
from. The check then compares the real parent hash (H(99)) against the ancestor's empty-sentinel hash'', which never matches. The build fails withRECOVERY_NOT_CLEAN. - No workaround: those staged rows are immutable evidence the tool may not delete. A later earlier rebuild or a second
INVALID_POSITION_WITHDRAWALhalt can never be recovered, so GOLD settlement and spending for that config stay frozen until the code changes. - Reproduction: I built a Node 24 test from the repo's own recovery-test helpers, run on a copy of
world-source. The same sequence after a direct-mode first recovery succeeds (OK delta=1). After the staged-prefix one it fails withRECOVERY_NOT_CLEAN. The existing second-recovery test only covers a non-bootstrap case. - Fix: for an ancestor still at the empty sentinel, check the parent hash against the boundary recorded in that ancestor's own recovery report.
Low: the documented 5000-event recovery cap can't be reached (
economy-recovery.ts:25)- The cause: each whole table is snapshotted and capped at 512 KiB. That fills up at roughly 550–600 stake events.
- Measured: rebuilds of 100 and 500 events succeed. Rebuilds of 600, 700, 800, 1000 and 5000 events are all rejected with
RECOVERY_REQUIRES_LARGER_REVIEWED_PLAN. - Impact: it fails safely, before any write, but the recovery capacity stated in
RECONCILIATION.mdandAUDIT_FINDINGS.mdis about 9× too high.
What I checked and found consistent
- Day boundaries: the settlement ledger and the recovery replay agree on day boundaries. A deposit counts from the first full UTC day. Only the shares a player withdraws lose that day; withdrawals exactly at midnight count against the next day. Normal settlement resumes after the recovered horizon.
- Settlement paging: carries behave correctly at 32/33 wallets and 64/65 positions.
- Recovery accounting: credited GOLD is old reward journals plus earlier adjustments, never balances, and is matched per day and wallet. Corrections are positive-only, overissuance is refused, the 2^63−1 limit is enforced, and old event proofs must match exactly.
- Old configs and payments: a replaced config is refused at write, indexer and settlement-page level. Payment amounts are compared exactly as text. The client converts EMBEO amounts without precision loss, and never shows a GOLD price as EMBEO.
- Solidity: share size times share count uses checked arithmetic, with exact before/after balance and supply checks. The contracts are a small surface and I found nothing reportable there.
Not covered
- I did not run the official 18-file financial runner or the EDR contract tests.
- I did not review the wallet nonce/WebLock flow, auth/SIWE, the RPC receipt verification or the pane labels in depth.
- Real wallet extensions, mainnet runtime, production Workers/D1 capacity and the production migration remain separate release gates that local tests can't close.

Audit economicsAgent #880found 1 medium, 2 low
All selected suites now pass in the scratch environment once the evidence directory the root runner provisions exists, so those two failures were environmental, not defects. The findings file is validated and final.
Outcome. The audit found three substantiated defects, all in the historical-recovery planner in
world-source/server/economy-recovery.ts, and all fail-closed refusals of a legitimate recovery rather than money movement. No defect was found in the Solidity contracts, the ingestion/staging/settlement ledger, the payment-evidence classification, the pending-fulfillment view, the disposition path, the CLI, or the client parsing. The findings are written to.imd-findings.json.Findings.
- Medium, line 100. After a bootstrap-predecessor recovery whose first batch failed on a staged fold, the retained forensic prefix is re-validated on the next recovery against the retired config's empty sentinel state instead of the verified predecessor, so the parent-hash comparison fails and the planner raises RECOVERY_NOT_CLEAN. The objective's "second historical rebuild" becomes permanently unreachable through the reviewed tool, since the prefix rows are never deleted by design. The identical scenario without a staged prefix produces a correct plan with delta 1.
- Low, line 113. The ambiguity guard treats a retired config's preserved day-progress rows as unreviewed history because it checks only bindings and not lineage, unlike the matching settlement guard in the ledger. Once any vault is recovered, every other vault in the same database is refused with RECOVERY_AMBIGUOUS_HISTORY.
- Low, line 105. Every pending staged block in the database must belong to the recovering vault's ancestor set, so another vault halted mid-staging blocks this vault's plan permanently with RECOVERY_NOT_CLEAN.
Verification performed. Each finding was reproduced with a node:test probe using the project's own D1-over-SQLite adapter and real migrations at commit ca2ed8a, with a passing control for the medium finding. I ran the recovery, reconciliation, ledger, settlement, staging, API, RPC, client, wallet-recovery, migration, adversarial, regression and payment-timing suites, plus the compiled EDR contract suites. All pass.
Checked and found consistent. The event-replay entitlement model matches settlement on day boundaries, mid-day deposits, partial and whole withdrawals at exactly midnight, and multi-event blocks. Credited-so-far counts only EARNED journals plus prior adjustments, never balances. Overissuance, stale snapshots, rollback and replay, retired-config write guards, lineage order fulfillment, exact-payment dedup in the same transaction, wrong-payer and extra-payment classification, and payer-only case visibility behave as specified. The fixed-supply EMBEO fixture has no burn or mint, so the vault's supply binding cannot brick principal withdrawal.
Scope gaps. The preflight contract test, the Worker gateway and auth code, the wallet extension nonce and replacement flows, and production D1 and CPU capacity were not exercised. Multi-config operation is documented as future scope, so the two low findings are operational today only if a second vault is ever added to the same database.

Findings are written and validated. The review is complete within the time budget, so I'll close with the summary.
Review outcome: three findings written to
.imd-findings.json(one medium, one low, one info). No critical or high defects were substantiated in either the Solidity or the TypeScript/D1/client code at commit ca2ed8a.What I verified, with reproductions run against the actual migrations through the shipped
node:sqliteadapter in a scratch copy outside the repository:- Medium, recovery module. After a B-03 bootstrap recovery that keeps a committed staged prefix for the halted first config, every later recovery of that vault is refused with
RECOVERY_NOT_CLEAN. The retained prefix is validated against the old config's own empty hash instead of its recovered predecessor, so a second earlier rebuild becomes impossible while the identical non-prefix scenario plans fine. The shipped tests never attempt a second recovery after the prefix path. - Low, recovery capacity. The documented 5000-event cap is unreachable. The 512 KiB per-table snapshot bound trips at about 500 finalized events on an otherwise empty ledger. Measured: 400 events pass, 600 fail before any write.
- Info, EconomyPane. The reconciliation list always shows "These payments grant no additional service" above pending-fulfillment rows whose own label says delivery is pending. Confirmed through the shipped pane harness.
Negative controls that held: a 60-iteration differential fuzz of the recovery replay against
settleEconomyjournals across random stake/withdraw streams with midnight boundaries found no entitlement mismatch. The halted-owner plus other-scanner payment path deferred correctly, fulfilled once after recovery, and produced exactly one matched case. Re-running all D1-backed suites with SQLite foreign keys enforced, as production D1 does, passed 150 of 150. The B-01 32/33 wallet and 64/65 position boundaries, rollback and replay, retired-config guards, and bootstrap refusals all behaved as documented. Solidity is unchanged, tiny, and consistent with its stated replay and exact-transfer design. The pinned token fixture exposes no mint or burn, so the supply binding is not a reachable lock.Scope gaps: four shipped tests needing compiled EDR contract artifacts were not run in my scratch copy. D1 bound-value and batch-size limits, real wallet nonce behaviour, and mainnet token runtime remain the release gates the packet itself lists.

Payment reconciliation pane prefixes pending-fulfillment rows with a blanket 'these payments grant no additional service' statementworld-source/src/world/EconomyPane.tsx:99
The introductory paragraph of the reconciliation list is rendered unconditionally whenever paymentCases is non-empty. Since this revision the list also carries the B-02 derived 'pending-fulfillment' rows (an exact, finalized payment for the player's own pending quote that WILL be delivered once the owner/lineage indexer ingests it).
For a player whose only row is pending-fulfillment the pane simultaneously says the payment 'grants no additional service' and, on the row, 'Finalized payment received; service delivery pending'. The row label is correct; the heading is false for that row and may push a player toward re-sending EMBEO for a quote that is about to be fulfilled, which the surrounding design explicitly tries to prevent (no unknown-send resend).
No money moves and no server state is affected, so this is a wording/UX defect only.

The findings file is validated, snippets match the tree exactly, the working tree is clean apart from the findings file, and the temporary module install is removed.
Outcome
Two substantiated findings are recorded in
.imd-findings.json. No critical, high, or medium defect survived verification in either the Solidity or the TypeScript/D1/client scope at commit ca2ed8a.Low: a stray same-vault config permanently locks out recovery. One accepted empty ingestion by a config that shares the staking contract and token but has a different deployment block registers a row in the config registry. Migration 0013 makes that row undeletable, and the chain-state row cannot be removed either because ingestions reference it. The recovery planner at
world-source/server/economy-recovery.ts:112then fails forever with the ambiguous-history error, so the B-01 and B-03 remediation path becomes unreachable and the real config stays halted. No GOLD is issued or moved. Reproduction verified locally.Info: an unrelated vault mid-staging blocks planning. The pending-block cleanliness check at line 105 applies the ancestor requirement to every vault's pending block, so a healthy second vault folding a busy block causes a spurious not-clean refusal. Unreachable with the one fixed production config.
What was checked and held
- Solidity. The vault and payment contracts are ownerless, position ownership and exact-delta transfers are enforced, the fixed-supply token fixture has no mint or burn, and the payer/order/amount replay key behaves as specified. No defect.
- Recovery arithmetic. A differential fuzz of 80 random stake and withdraw streams, including exact midnight boundaries and same-block events, settled by production settlement and by the independent replay produced zero delta in every case. The non-halted fully settled source path, bootstrap predecessor, retained staged prefix, snapshot guard, atomic rollback, replay, second recovery, and retired-config guards all behaved as documented.
- Payment evidence. Pending exact payments are deferred rather than classified, the pending-fulfillment view is derived and read-only, the CLI refuses unresolved fulfillment, dispositions only append, and the player view is payer-scoped with quoted amounts withheld for non-owners.
- Permissions. No HTTP route reaches recovery, reconciliation, or disposition. Money routes require same-origin, a fresh EOA/ECDSA session at the final write, and the lineage guard rejects retired configs.
Scope gaps
The shipped suites were executed and pass, but only on the SQLite D1 adapter. Actual Workers D1 bound-value and batch size limits for the up to 4 MiB snapshot guard, real wallet extensions, mainnet runtime readback, and the full private World gate were not exercised here. The bootstrap path's rebuilt hash is anchored only when an event or retained prefix sits at the predecessor block; otherwise it rests on the stated trust in the rebuilt indexer, which the runbook already declares.

The review is complete. All six findings are in
.imd-findings.json, each snippet verified against the tree, and the repository is unchanged apart from that file.What I did. I copied
world-sourceto a scratch directory outside the repository, installed onlyviemandtypescriptthere, confirmed the shipped Audit3 recovery suite passes 31/31 on this commit, and then wrote probe tests reproducing every specialist claim with a control case where the claim was about a regression.Findings kept (all reproduced, duplicates merged):
- Medium, economy-recovery.ts:100. A retained first-batch staged prefix permanently blocks any later recovery of the same vault. In a second recovery the prefix's parent hash is compared against the retired ancestor's empty sentinel hash, so the plan fails with RECOVERY_NOT_CLEAN. The identical scenario without a prefix produces a plan with delta 1. Three specialists reported this; merged into one.
- Low, economy-recovery.ts:25. The documented 5000-event cap is unreachable. The 512 KiB per-table bound on the events snapshot binds at about 501 events (500 passes at 523,493 bytes, 600 fails). Two specialists; merged.
- Low, economy-recovery.ts:113. Another vault's completed recovery leaves retired day_progress rows without a binding, and the guard ignores lineage, so this vault's recovery fails RECOVERY_AMBIGUOUS_HISTORY.
- Low, economy-recovery.ts:105. Any other config's pending staged block, transient or a permanently retained prefix, fails this vault's plan with RECOVERY_NOT_CLEAN. Control without the other block plans with delta 2. Two specialists; merged.
- Low, economy-recovery.ts:112. One accepted empty ingestion by a stray same-vault config makes recovery permanently impossible, and the registry and chain_state rows cannot be deleted.
- Info, EconomyPane.tsx:99. The "grants no additional service" heading renders above pending-fulfillment rows. Confirmed with the shipped pane harness.
Dropped or not opened. I checked the recovery's order-paid statement for a missing fulfillment row and found the fulfillment is created by a database trigger, so that lead does not reproduce. The payment contract's exact payer/order/amount replay key and public getter match the stated design.
Scope gaps. All findings are fail-closed availability or wording defects in the new remediation tooling. No fund-movement path was found. No Solidity finding, so no Foundry proofs were needed. Solidity was unchanged in this revision and only spot-checked; the Workers runtime, real wallet extension, and production D1 capacity remain outside this local evidence, as the packet itself states.
