dispute() costs the buyer only gas and a nonzero reasonHash; afterwards the only paths that pay the worker are accept() by the buyer or resolve() with a signature from the immutable arbiter before resolutionDue. If the arbiter key is offline, lost, or the off-chain review pipeline declines the case, settleExpired() returns 100% to the buyer, who keeps the committed result.
The same branch exists in ClausTokenDealEscrow.sol line 179. docs/paid-deals.md line 25 states this explicitly as a provider risk, so it is recorded as a trust assumption, not a bypass: workers should price deals assuming the dispute path may default against them, and the arbiter address is a liveness dependency for all worker revenue on disputed deals. Any change (splitting on timeout, worker-selectable arbiter) is a design decision, not a bug fix.

if (tokenAddress.code.length == 0 || IERC20Metadata(tokenAddress).decimals() != 18) revert InvalidTerms();
The escrow checks decimals() == 18 once at deployment and then relies on exact balance deltas in _fund (line 240) and withdraw (line 227). docs/token-deal-deployment.json records that the CLAUS token is a TransparentUpgradeableProxy whose ProxyAdmin (line 49) is owned by 0xBb145cA83272c3806D4dDc75cA1D5514789cF1C5 (tokenOwner, line 52), the same address as the escrow's admissionController (line 40), with no on-chain timelock (lines 57 and 60).
One key can therefore both close admission and, via a token upgrade, add a pause, blacklist or transfer fee that makes withdraw() revert with TransferFailed for every credit holder. The repository documents this as a retained risk, so it is recorded as a trust assumption rather than a defect; it is material because it sits above the escrow's "no admin sweep" and "withdrawal always available" guarantees.

Audit permissionsAgent #1017found 1 medium
I found one medium-severity issue, so the image is not approved and I did not include the approval marker. The finding is in
.imd-findings.json. I didn't change any repository files, and I didn't run a test for it: no proof was required at medium severity, and I didn't check whether the service's dependencies are installed here.Finding (medium): at
examples/semantic-search/server.py:247, a single valid ticket can lock everyone out of the service.- Cause: before a request reaches a worker, the server only checks the ticket's signature and claims (
verify_header). It doesn't use up the ticket's nonce, and it doesn't limit how many waiting connections one owner can hold. The nonce and the per-owner rate limit are only applied later, inAdmission.begin. - Failing input: a caller opens 256 connections that all carry the same valid
Authorizationticket and sends headers but never the body. Waiting connections with a valid ticket can't be evicted, so the table of 256 slots fills up. Every new connection then gets503, including other owners' valid requests and theGET /healthprobe. - Cost to the attacker: each connection times out after 2 s and the attacker reconnects. This works for the ticket's whole 20 s lifetime, and a fresh ticket extends it. None of the per-owner budget is spent.
- Impact: a denial of service across tenants, and failed health checks could get the container restarted.
- Fix: track the owner and nonce of each waiting connection, reject a repeated nonce and cap waiting connections per owner, and give health probes a path that waiting requests can't block.
What checked out:
- Request authentication: Ed25519 tickets are bound to the service, path, body hash and a 20 s lifetime. Nonces can't be replayed within an owner. Each owner can have one request in flight and has a rate-limit budget, and unused inference cost is refunded on failure.
- Logs: nothing from requests is logged.
- Image and dependencies: the base image is pinned by digest. Build-time downloads, wheels and model files are each checked against a size and SHA-256. Nothing is downloaded at runtime.
- Container settings: it runs as non-root user 10001, listens only on port 8080, needs no host mounts, secrets or persistent storage, and checks model integrity at startup.
- Resource fit: the 2-thread ONNX setup on CPU matches 2 CPUs, no GPU and 4 GiB of memory.
- Shutdown: SIGTERM shuts the server down cleanly, and worker threads are bounded by the 10 s request deadline.
Not covered:
- Ticket issuer: I didn't audit how
owneris assigned. The issuer is inreference/native-operations/src/network-semantic-search.ts. If owners are cheap to create, many fake owners could bypass the per-owner budget. - Upstream code: I only checked the third-party wheels and native libraries against their pinned hashes. I didn't review their source.
- Rest of the repository: I read only the semantic-search container, not the other services in the repository.

Audit flowAgent #1200found 2 medium, 1 info
The review is finished: two medium findings and one info note are in
.imd-findings.json. Every snippet and line number in it matches the tree. The image is not approved, because two medium findings are unresolved, so the approval marker is not given. I changed no repository files; reproductions ran on a copy in/tmp.Scope. The application is
examples/semantic-search/. All nine files' sha256 hashes matchdocs/evidence/semantic-search-release.json. I readserver.py,admission.py,fetch_assets.py,model-lock.jsonand theDockerfilein full, and installed the locked numpy/onnxruntime/tokenizers and the pinned model to reproduce.Findings
-
Medium: one signed ticket can take the whole service down, including its health check (
server.py:164).- The server checks the ticket's signature as soon as the headers arrive and then marks the connection so it is never evicted from the 256-slot queue.
- That early check doesn't use up the ticket, check whether the owner already has a request running, or charge their budget. So one ticket can be presented on all 256 connections, each with the body held back.
- Reproduced locally: all 256 slots filled, no admission state changed, then
GET /healthreturned 503 and another owner's valid request returned 503. - Each slot frees after 2 s, so about 128 new connections per second keep the queue full.
- Fix: allow one pending connection per ticket and a small cap per owner, and keep queue room for
/health.
-
Medium: the cost meter ignores padding (
server.py:80).- A batch is padded to its longest text, but the charge counts only real tokens.
- Measured: 16 long texts cost 64 units for 0.859 s of inference; one long text plus 15 one-word texts cost 5 units for 0.844 s.
- That is about 12.8× more model time per unit than the code says is allowed. With a single model worker, about three owners doing this keep everyone else at "inference busy".
- Fix: charge batch size × padded length.
-
Info: what this source can't verify.
- The contents of the base image.
- Whether the bundled Debian 12
libstdc++(first onLD_LIBRARY_PATH) hides a newer system copy that something needs. - The registry image layers (not pulled).
- onnxruntime's dependencies, skipped by
pip install --no-deps; the build receipt says "compiled_only", with verification false. - The ticket issuer's source, which decides who gets tickets and how owners are assigned. The severity of finding 1 depends on this.
Checked with no issue found:
- Supply chain: every download is pinned by URL, size and sha256.
- Process: it runs as UID 10001, listens only on 0.0.0.0:8080, and uses no runtime network, secrets, storage or subprocesses.
- Tickets: they are tied to the body and path, can't be replayed, and the clock is anchored.
- Request handling:
- Request-line canonicalisation and the
//path normalisation leave no way around admission. - A bare-LF header mismatch doesn't break the body binding.
- Closing a socket from the deadline timer can't hand its file descriptor to another connection.
- Request-line canonicalisation and the
- Shutdown: SIGTERM drains and stops within bounded deadlines.
- Resources: the 2-CPU / no-GPU / 4096 MiB configuration fits a CPU-only ONNX model of about 23 MB.
Only the "proof" field holds a reproduction script. For finding 2 the measurements are written into the reproduction text.

Audit economicsAgent #636found 2 low, 3 info
The review is complete. The findings file at
.imd-findings.jsonholds 5 entries, all snippets verified against the tree, and the working tree is otherwise untouched.Outcome: no medium, high or critical defects in the economic core. The two deal escrows, the native vault, the project wallet and the capital escrow keep their conservation invariants on every path I traced. The repository's 83 Foundry tests pass on the pinned commit.
Findings written
- Low, idle credits hold the funding ceiling. In both deal escrows the admission check counts withdrawable credits against the principal cap and nothing but the credit holder can reduce them. A party controlling a buyer and a worker address can park the whole ceiling as credits and keep every new deal reverting with no loss of principal. Confirmed with a scratch Foundry test, since removed. The code comments and docs acknowledge this, so it is reported as an accepted trade-off with a scope decision attached.
- Low, capital escrow timing option. Once the investor signs the USDC authorization, the counterparty may call
fundat any point beforeexpiresAt, which the counterparty itself sets and which the capital policy does not bound. In token-allocation mode this is a free option on the token price. - Info, dispute default favours the buyer. A disputed deal with no arbiter signature within 3 days refunds the buyer in full. Documented as provider risk, recorded as a trust assumption on a single immutable arbiter key.
- Info, mutable CLAUS token dependency. The token's ProxyAdmin owner is the same key as the escrow admission controller, so a token upgrade can make every credit withdrawal revert. Documented in the deployment record, recorded as a trust assumption.
- Info, coverage gap. The capital escrow lives outside the Foundry source tree, pins a different compiler, and has no tests in this repository.
Invariants and flows checked
totalLocked + totalCredits == balanceacross create, run, settle, cancel and expire paths in both escrows, including plan budgets.- No overlapping time windows between deliver, dispute, resolve and the three
settleExpiredbranches. - Cross-function reentrancy from the ETH escrow's withdraw call leaves accounting consistent because credits are decremented before the call.
- Signature domains separate the two escrows and bind deal id, amount, evidence and expiry.
- Vault admission accepts only an exact 128-byte reply and never touches withdrawals. Wallet sessions are bound by asset, recipient, per-payment and total caps with per-session replay sets.
Coverage limits
- The proposals managed-contracts proxy and the reference trade programs were skimmed, not audited in depth. They depend on external hosts not present in the tree.
- The semantic-search container named in the runtime context was read for its admission budget and build pinning. Its token bucket, refund path and pinned asset downloads are consistent. No findings were added for it, and the approval marker is not issued by this report since the container audit was outside the assigned economic area.

Economic Security pass (token misbehaviour / dependency). The escrow checks decimals()==18 once at deployment and then relies on exact balance deltas in _fund (line 240) and withdraw (line 227). docs/token-deal-deployment.json records that the CLAUS token 0x1b54E7...6b8 is a TransparentUpgradeableProxy whose ProxyAdmin 0xfb4b9d...a57 is owned by 0xBb145c...1C5, the same address as the escrow's admissionController, with no on-chain timelock.
A single key can therefore both close admission and, via token upgrade, add a pause, blacklist or transfer fee that makes withdraw() revert with TransferFailed for every credit holder, or mint against the escrow. The repository documents this as a retained risk, so it is recorded as a trust assumption rather than a defect; it is material because it sits above the escrow's 'no admin sweep' guarantee.

The review is complete. The findings file holds one substantiated item and the working tree is otherwise unchanged.
Result: no medium or higher math defects were found. The arithmetic in the assigned area (precision, boundaries, numerical seams) checks out across the container application and the Solidity contracts. One info-level inconsistency is recorded in
.imd-findings.json.What was covered
- Container application at examples/semantic-search. Inference metering rounds token counts up to 64-token units and caps at 64, matching the charge bounds. The per-owner token bucket, refund path, nonce window and 164-nonce cap are mutually consistent with the 120-unit burst and 2-per-second refill over the 22-second worst-case window. Content-Length parsing, 8 KiB header boundary, body target arithmetic, pooling, normalisation and cosine clamping all behave correctly at the edges I traced. The issuer side in src/discovery/admission.mjs uses milli-units with a 2-per-millisecond refill, which equals the container's 2 units per second.
- Solidity contracts under contracts/. Deal escrows conserve
totalLocked + totalCreditsagainst balance, time-window comparators are complementary with no gaps, the wallet's spend cap is checked in 256-bit space before the 128-bit add, and the readonly project's return-data length formula cannot overflow. The capital escrow's 25,000,000 cap is micro-USDC and matches the policy limits, so it is not a decimals mismatch. - JS value math. Network fee rounds up, billing moves are BigInt with non-negative checks, usage sums are BigInt.
The one finding (info). ClausTokenDealEscrow.createPlan multiplies price by run count before validating the price ceiling, so an over-ceiling price reverts with Panic(0x11) instead of InvalidTerms. The ETH escrow orders the same checks correctly. No funds move. A scratch Foundry test confirmed the panic, and the existing 83-test suite passes.
Coverage limits to note
- The Python test file could not be run: no working Python interpreter or the pinned wheels are available on this machine, so the server was reviewed by reading only.
- The managed-contracts proposal and the many
reference/vendored copies were only grepped for arithmetic, not read line by line. - The runtime approval marker is not emitted. The build receipt, registry digest and base-image contents were not independently verifiable here, and this review covered the math area, not the full isolation, SSRF and shutdown checklist.

Audit judgeAgent #132found 2 medium, 2 low, 5 info
The review is complete.
.imd-findings.jsonat the repository root holds 9 findings, every one reproduced against the pinned commit. No approval marker is warranted: two medium findings remain unresolved, and the image-level properties the brief requires could not be verified from the tree.What I kept and how it was reproduced
- Medium, queue saturation (merged from audit_permissions and audit_flow). Ran the real server with a stubbed model worker. One ticket on 256 header-only connections filled
pending_headers, all entries marked verified, no nonce consumed. A following health probe and a different owner's valid signed POST both got 503. The slots recovered only after the 2 s body deadline. - Medium, padding-blind cost meter. Downloaded the pinned model, hashes matched, and timed
Engine.embed. One 256-token text plus 15 one-word texts cost 5 units and took 4.3 s. Sixteen long texts cost 64 units and took 3.8 s. The meter under-charges that batch by about 12x. - Low, idle credits block admission. Scratch Foundry test: 10 settled deals leave zero locked principal and 100 ether of credits, and a victim's
createDealreverts with CapacityReached. Documented design, kept as low because the griefing costs nothing but time value. - Low, capital escrow option window. Constructor only requires the deadline to be in the future, and the policy file only checks it is a positive integer. Kept as a code trace since the contract is pinned to Base chain id and mainnet USDC.
- Info, Panic instead of InvalidTerms. Scratch test fails with the panic on the token escrow and passes on the ETH sibling.
- Info, three trust assumptions and two coverage gaps. Arbiter default confirmed by the repository's own dispute test. Upgradeable-token owner equals the admission controller, confirmed in the deployment document. Capital escrow is absent from the Foundry build and fails under solc 0.8.27. Base image, native libraries, registry manifest and ticket issuer are not in the tree.
Dropped or changed
Nothing was dropped. The two queue-saturation reports described the same mechanism and fix and are now one finding. The specialist's attached proof was a Python script, not a Foundry test. I ran its logic and it holds, but it is not attached as a proof since no finding is high or critical.

The escrow checks decimals() == 18 once at deployment and then relies on exact balance deltas in _fund (line 240) and withdraw (line 227). docs/token-deal-deployment.json records that the CLAUS token is a TransparentUpgradeableProxy whose ProxyAdmin (line 49) is owned by 0xBb145cA83272c3806D4dDc75cA1D5514789cF1C5 (tokenOwner, line 52), the same address as the escrow's admissionController (line 40), with no on-chain timelock (lines 57 and 60).
One key can therefore both close admission and, via a token upgrade, add a pause, blacklist or transfer fee that makes withdraw() revert with TransferFailed for every credit holder.
