The findings file `.imd-findings.json` is in the repository root with two entries, and no source or configuration files were changed. The harness excludes the findings file and `test/scratch/` from git by design, which is why the tree reads clean.\n\n**Scope and method.** I applied the Math Precision, Boundary and Numerical Gap passes to all six contracts under `src/`, then checked authorization, replay, expiry, recovery, dependency changes, custody and denial of service across the same files. The existing suite of 41 tests passes offline. The code contains no multiplication, division, shifts or narrowing casts other than one `uint64(block.timestamp)`, so the arithmetic surface is small and I could walk every comparison, bound and external boundary by hand and with scratch tests.\n\n**Findings written to the file**\n\n- **Low, `src/ClausNativeVault.sol:15`.** The vault forwards a fixed 250,000 gas to the admission project, but the project loads its whole stored configuration with cold SLOADs before calling the module. Measured cost of the policy call was 16,547 gas at 64 bytes, 250,689 at 3,488 bytes, 252,877 at 3,520 bytes and 572,437 at the project's own 8,192-byte limit. From 3,520 bytes upward every deposit reverts with `DepositDenied` even though the policy returns admitted with no cap. Withdrawals are unaffected, so this is fail-closed, but it is an undocumented limit on the admission path that a reviewed allowlist-style policy would hit. The proof test under `test/scratch/VaultPolicyGasBudget.t.sol` fails on current code and passes once the budget covers the maximum configuration, for example 800,000 gas.\n- **Info, `src/ClausNativeVault.sol:44`.** Deposits via `receive()` cannot succeed under the 2,300-gas stipend, so `transfer` and `send` from contracts always fail with a misleading `DepositDenied`. Fail-closed and no principal credited. Verified with a scratch test.\n\n**Verified properties, not assumptions.** Every EIP-712 typehash matches its struct field order, so standard signing tooling produces matching digests. The uint128 spend accounting in the wallet is widened to uint256 before the total check. All timestamp bounds in the executor leave a non-empty execution window and the accepted delay can only increase. Withdrawals never touch the admission policy, so policy failures or upgrades cannot trap principal. Forced ETH is never attributed. Reentrancy into deposit or withdraw via the recipient callback reverts. Recovery scheduling and cancellation both advance the generation, invalidating approvals signed before or during the pause. Session nonces and quote hashes are scoped per session, and revoked session identifiers can never be reauthorized.\n\n**Trust assumptions retained, as documented by the requester.** The recovery owner can rotate the Claus signer after the delay and nobody else can cancel. Claus can burn any project's approval nonces outside a pending recovery. A project owner plus Claus can close vault deposits at will. The wallet owner holds arbitrary call authority. A contract owner or signer using ERC-1271 is trusted to validate correctly.\n\n**Not covered.** No static analyser ran, since none is provided. No fork or mainnet token behaviour was tested. A clean result on the remaining passes is evidence of review, not proof of absence of defects.","treeHash":null,"usage":{"cachedInputTokens":1496509,"inputTokens":546,"model":"claude-fable-5-1","outputTokens":37892,"runtime":"claude","turns":28,"wallClockMs":582001}},{"artifacts":[],"attempt":1,"bundleHash":null,"device":"d20c1a95c50699ea","findings":[{"citation":"resolved","description":"Merged from audit_math (1b683fec) and audit_economics (1b16ae90).

The review is complete.\n\n## Outcome\n\nThe pinned Claus Network contracts hold up under the Economic Security, Invariant and Flow Gap passes. I found no fund-loss, replay, authorization or recovery defect. The findings file `.imd-findings.json` carries two substantiated, non-critical items; neither warrants a proof test.\n\n**Findings written**\n\n- **Low, `src/ClausNativeVault.sol:15`.** The fixed 250,000 policy gas budget is spent copying the admission project's stored configuration before the module runs. A configuration of 4096 bytes or more makes every deposit revert with DepositDenied even when the module admits it. Unreachable with the shipped ClausVaultAdmission, which requires exactly 64 bytes, so it only matters if the admission module is later upgraded. Withdrawals are unaffected.\n- **Info, `src/ClausNativeVault.sol:44`.** The receive path runs the policy call, so senders forwarding the 2300-gas stipend via `transfer` or `send` can never deposit. No value is lost and accounting stays intact. A documentation note suffices.\n\n**Verified properties** (by reading plus 41 passing project tests and scratch probes I ran then deleted)\n\n- Vault: contract balance is always at least total principal, total principal equals the sum of per-account principal, and a deposit then full withdrawal returns exactly the deposited amount. Forced ETH is never attributed. Failed payouts keep the claim. Policy changes and policy failure never block or tax withdrawals.\n- Wallet: a session can move only its bound asset to its bound recipient, within per-payment and total limits, inside its time window. Nonce and quote replay are scoped per session. Revocation permanently retires an ID, including pre-signed future generations. Early renewal resets the spent counter, but combined outflow stays bounded by the sum of all owner-authorized totals, which I confirmed with a probe.\n- Executor: approvals are bound to chain, executor, target, versions, code hashes, policy, authority and Claus generations and a per-project nonce. Owner transfer and signer recovery pause upgrades immediately. Every ABA sequence bumps a generation. The queue delay is measured from the public queue call and cannot be shortened. Registration nonces, project IDs and the one-hour to 365-day delay bounds behave as documented.\n\n**Assumptions and trust, not defects**\n\n- The per-account deposit ceiling is Sybil-bypassable and sets no aggregate cap; the README states it as per-account.\n- The admission project owner, the recovery owner and the Claus signer hold the documented pause and invalidation powers. The recovery owner can pause indefinitely. Signer EOAs are assumed to stay plain EOAs, since the vendored SignatureChecker falls back to ERC-1271 for any signer with code.\n- ERC20 amounts are nominal; fee-on-transfer or rebasing assets reduce what a recipient receives, as the README discloses.\n\n**Coverage limits.** The Balance Lens and the admission module were read but are outside the assigned economic area.

Delay floors cannot be lowered.\n- Vault withdrawals never touch the policy. Forced ETH is not credited.
