• 1.mediumHealth check and all inference share one 24-slot worker pool that idle, unauthenticated TCP connections exhaust before any request is readexamples/semantic-search/server.py:88

          if not self.workers.acquire(blocking=False):

  Server.process_request takes one of the 24 worker slots for every accepted TCP connection before a single byte has been read and releases it only when the handler thread exits. Handler.setup sets a 5 s socket timeout, so a connection that never sends a request line holds its slot for 5 s (up to the 10 s absolute deadline if bytes are dripped).

  GET /health, the manifest healthPath, is served from the same pool: once 24 slots are held, process_request calls shutdown_request on every new connection, which is closed with no HTTP response at all (not a 429 or 503). The orchestrator therefore sees the instance as down and will restart or deschedule it; each restart also clears the in-memory replay table. Keeping the pool full needs about 5 new idle connections per second from one source with no account or ticket.

  The README disclaims unlimited-load protection, but this is an application-level cap reachable at trivial rates, not host network capacity. Fix preserving the design: do not charge a slot until a request line has arrived (accept, read with a short ~1 s pre-header timeout, then admit), or reserve capacity that only /health can use (separate listener or reserved slot), and answer surplus connections with a 503 so the probe can distinguish overload from a dead process.

  Merged from two specialists (audit_flow, audit_permissions) reporting the same mechanism.

  whole finding

  State: Server/Handler from server.py with the real Engine and an Admission with a test key, serve_forever in a thread (the shipped test harness).

  Input: open 24 TCP connections to the port and send nothing; 0.3 s later issue GET /health with a 2 s timeout every 0.5 s.

  Expected: /health keeps returning 200 while the idle sockets wait.

  Actual (measured here): baseline /health 200; with the idle sockets open every probe at t=0.0, 0.5, 1.0, 1.5, 2.0, 2.5 s fails with RemoteDisconnected (server closed the socket without any response bytes; a raw 25th connection sending a complete GET /health received b''); probes return 200 again only from t=3.0 s, when the 5 s socket timeout in Handler.setup frees the slots.

  Re-opening the 24 sockets every ~4 s keeps the probe failing indefinitely.

  Admitted POSTs are refused the same way during the window because the slot check runs before admission.

• 2.mediumPer-principal fairness is defeated: one owner's free agent principals saturate the single inference slot and other principals get 429 inference_busyexamples/semantic-search/server.py:53

          if not self.lock.acquire(timeout=3):

  The service runs one model inference at a time (BoundedSemaphore(1)); any other admitted request waits at most 3 s and then fails with 429 inference_busy, which also consumes the caller's one-use ticket and a rate token. The only fairness control is per principal (one active request per sub, 120 burst / 2 per second, admission.py lines 67-72, mirrored in src/discovery/admission.mjs).

  The issuer binds sub to credential.principalId, and a project owner can mint agent principals for free: ACCESS_DEFAULTS allows 32 agents per project and 10 projects per owner (src/access/index.mjs line 8, src/identity/index.mjs line 246), each with its own mandate carrying service.call and so its own full allowance at issuer and model.

  With k agents each keeping one maximum-size request (16 texts truncated to 256 tokens) in flight, every other principal waits behind up to k inferences. The README claim that multiple credentials or projects do not create separate capacity holds per principal but not per owner, which is the actor who controls the agents. Issuer cost is small (about 8-12 tickets/s, under the 3000-per-5-minute global cap; the 300-per-peer cap only spreads minting over a few source addresses).

  Fix options that keep the design: carry the owner or project id in the ticket and key the active-request limit and bucket by it at the model; or bound in-flight inference with a FIFO queue so no admitted request waits behind more than N others; or lower the per-request ceiling so one slot cannot be held for a full inference of maximal size.

  whole finding

  State: real Engine, Server with Admission(test key), pinned to two CPUs with taskset -c 0,1 to match the 2-CPU lease. k attacker threads each use a distinct sub (agent0..agent{k-1}) and loop POST /v1/embeddings with {"input": [16 strings of ~1740 chars, each >256 tokens]} (body 29,655 bytes) and a fresh ticket per body; one legitimate sub posts {"input":"hello"} every 0.5 s for 12 s.

  Expected (README): the legitimate principal keeps being served because capacity is per principal.

  Actual (measured here, a single max-size inference takes 0.31-0.33 s on this CPU): k=1 median latency 0.10 s, all 200; k=4 median 0.97 s, all 200; k=8 median 2.12 s, max 2.21 s, all 200; k=12 median 2.98 s, max 3.01 s, 1 of 4 legitimate requests 429 inference_busy; k=16 median 2.92 s, 1 of 4 requests 429.

  The attackers still complete 3-7 requests each.

  A slower vCPU (the specialist measured 0.76-0.95 s per max inference) reaches the 429 cutoff at k=8.

  12 agents are well within one owner's free allowance of 320.

• 3.lowGlobal 2048-principal admission table lets one owner's free agent principals lock out every new principal with 503 admission_capacity for 60 s at a timeexamples/semantic-search/admission.py:65

              if len(self.used) >= 4096 or (previous is None and len(self.callers) >= 2048):

  Admission.begin keeps one entry per distinct ticket subject and refuses any subject it has not seen with 503 admission_capacity once 2048 entries exist. Entries are dropped only after 60 s of inactivity.

  Agent principals are free and distinct subs (32 per project x 10 projects per owner, src/access/index.mjs line 8), so seven owner wallets hold 2240 agent credentials; presenting one valid ticket per agent within 60 s (the body may be one that fails validation, so no inference is spent) fills the table and every first-time principal, including the operator's own caller after a restart, is refused for the following 60 s.

  Already-admitted principals continue, so the README statement that capacity rejection never evicts live protection holds, but the cross-tenant 503 is not described. Sustaining it needs about 2048 tickets per minute, above the issuer's 600-per-minute average, so the outage is roughly one minute per five-minute window.

  Fix: key the table (or a per-owner sub-bound) by the owner/project the issuer puts in the ticket, or make the newcomer limit per unit time rather than per table size and expire idle entries sooner. Merged from two specialists (audit_flow, audit_permissions).

  whole finding

  State: Admission(CONFIG, clock=lambda: now, monotonic=lambda: now) with a test key.

  Input: 2048 valid tickets with distinct sub values sub0..sub2047, each begin() then finish(), then one valid ticket for sub "fresh".

  Expected: fresh is admitted (its own 120-token allowance is untouched).

  Actual (measured here): begin() raises AdmissionError(503, "admission_capacity") for fresh, while a ticket for the existing sub5 is still admitted; after advancing the monotonic clock 61 s, fresh is admitted.

  The lockout is renewable by re-issuing one ticket per farmed principal within each 60 s window.

• 4.lowReplay table is pruned by the non-monotonic wall clock, so a clock step forward then back re-admits an already used ticketexamples/semantic-search/admission.py:60

              self.used = {k: v for k, v in self.used.items() if v > now}

  The one-use guarantee is kept by self.used keyed on nonce and pruned when the stored exp is not greater than the current wall-clock millisecond (now comes from self.clock, time.time). The per-caller refill correctly uses time.monotonic, but the replay prune and the exp check both use wall time.

  If the host wall clock steps forward past a ticket's exp, any later begin() call prunes the nonce; if the clock then steps back into the ticket's 20 s window (NTP correction, VM clock resync after migration), the same signed ticket passes the exp check again and its nonce is gone, so it is admitted a second time and consumes another inference. Requires a host clock change, not an unprivileged caller, hence low.

  Fix: store a monotonic expiry (used[nonce] = tick + (exp - now)/1000) and prune with v > tick, keeping the wall-clock exp check as is.

  State: Admission(CONFIG, clock=lambda: wall, monotonic=lambda: mono) with wall=1700000000.0, mono=1000.0.

  1. begin(T) for a valid ticket T (iat=now, exp=now+20000): admitted; finish(T).

  2. begin(T) again: AdmissionError 401 admission_used (correct).

  3. wall += 25, mono += 25; begin() for another sub runs the prune: used table shrinks to 1 entry (the new one), T's nonce is gone.

  4. wall -= 25 (back to the original second).

  5. begin(T).

  Expected: 401 admission_used.

  Actual (measured here): admitted, claims returned with T's nonce.

• 5.lowClient-caused failures inside the inference path (lone UTF-16 surrogate, deeply nested JSON) are answered 503 inference_unavailable instead of 400examples/semantic-search/server.py:204

          except Exception:

  do_POST maps only ValueError and UnicodeError to 400; every other exception becomes 503 inference_unavailable.

  Two inputs a direct caller controls reach that branch: (a) a string that JSON allows but cannot be UTF-8 encoded (a lone surrogate from the escape \ud800) passes the isinstance/strip/len checks in Engine.embed and makes tokenizers 0.21.4 encode_batch raise TypeError while the single inference semaphore is held (it is released by finally, no leak); (b) a body of 60,000 opening brackets within the 64 KiB cap makes json.loads raise RecursionError.

  In both cases the caller's malformed input is classified as a service outage, and the admitted one-use ticket and one rate token are consumed. Only a direct caller can trigger these; catalogue text produced by the network passes a well-formedness check.

  Fix: reject texts for which t.encode("utf-8") fails in the validation branch of embed, and add TypeError and RecursionError to the 400 handler (or wrap json.loads).

  whole finding

  Input A: POST /v1/embeddings with a valid ticket and body {"input":"a\ud800"} (json.loads yields a 2-character str that passes validation).

  Expected: HTTP 400 with a client error code.

  Actual (measured here with the pinned model): Engine().embed(["a\ud800"]) raises TypeError("TextEncodeInput must be Union[...]"), which do_POST answers as 503 {"error":"inference_unavailable"}; engine.lock value is back to 1 afterwards.

  Input B: body of b"[" * 60000 with a matching bodyHash.

  Expected: 400 invalid_json.

  Actual: json.loads raises RecursionError, answered 503.

• 6.lowReference client bounds documents by UTF-16 length while the service caps the body in bytes, so a non-ASCII catalogue page fails the whole search with 413reference/native-operations/src/network-semantic-search.ts:46

    docs.push({id:p.id,text:text.slice(0,2048).replace(/[\uD800-\uDBFF]$/,''),project:p});

  semanticNetworkSearch truncates each document to 2048 UTF-16 code units and posts 15 per request; the service (server.py MAX_BODY) rejects any request whose Content-Length exceeds 65,536 bytes with 413 request_size_invalid before parsing. A character limit and a byte limit only agree for ASCII.

  Project descriptions are validated with prose(description, 500) (src/projects/index.mjs line 172), non-ASCII allowed, and agent and service names are serialised into the same text, so CJK-heavy projects produce documents of up to 6,144 bytes each. When a 15-document window contains 11 or more such documents the batch exceeds the cap, the service answers 413, json() throws and semanticNetworkSearch aborts for every caller of that page.

  Any project owner can publish such text, but the page composition is needed, so low. Note this client is not the live client for the audited image (see the consumer-mismatch finding).

  Fix: measure Buffer.byteLength of the serialised batch and split or shrink documents until it is at most 65,536 bytes.

  whole finding

  Input: a network_overview page whose 15-document window contains 11 projects each serialising to 2048 three-byte characters.

  The client builds JSON.stringify({query:"q", documents: 15 x {id, text}, limit:5}).

  Measured here with node: 15 heavy CJK documents = 93,157 bytes; 11 heavy + 4 empty = 68,581 bytes; 10 heavy = 62,437 bytes; 15 x 2048 ASCII = 31,717 bytes.

  Expected: the client batches so each request stays within the documented 64 KiB body limit.

  Actual: server.py do_POST line 164 rejects int(Content-Length) > 65536 with 413 {"error":"request_size_invalid"}; the client throws network_request_failed and no results are returned.

• 7.infoResponses disclose the interpreter version through the stdlib Server header and unsupported methods return the stdlib HTML error pageexamples/semantic-search/server.py:133

          self.send_response(status)

  Handler.reply calls BaseHTTPRequestHandler.send_response, which emits Server: BaseHTTP/0.6 Python/3.12.x and Date headers on every response including the public /health. Unsupported methods and malformed request lines fall through to the stdlib send_error path, which returns text/html rather than the service JSON shape. No secret leaks, but the exact interpreter version of the pinned image is advertised to anonymous clients.

  Fix: override version_string (or set server_version/sys_version) on Handler and set error_message_format/error_content_type to a JSON body.

  Input: GET /health, then a raw PUT /v1/embeddings, from an anonymous client.

  Expected: no interpreter version in response headers and a JSON error body for unsupported methods.

  Actual (measured here): "Server: BaseHTTP/0.6 Python/3.12.15" on the 200 reply; for PUT a "501 Unsupported method ('PUT')" response with Content-Type text/html;charset=utf-8 and a 356-byte HTML page.

• 8.infoResource suitability for the 2-CPU, no-GPU, 4096 MiB, no-storage lease: adequate, but single-threaded inference leaves the second CPU idleexamples/semantic-search/server.py:41

          settings.intra_op_num_threads = 1

  Assessment, not a defect.

  The application matches the manifest: CPU-only onnxruntime provider (gpu null is correct); peak RSS measured here at 363 MiB after warm-up and three maximal batches against the 4096 MiB allowance; nothing is written at runtime (PYTHONDONTWRITEBYTECODE=1, UID 10001 cannot write /app, no volume) so storageGiB 0 is correct; one listening port 8080; /health answers immediately after the sub-second model load; SIGTERM stops accepting and drains within the 10 s connection deadline (shipped test passes).

  However intra_op_num_threads=1 together with a single inference permit means the second CPU of the lease is never used for inference; worst-case throughput is bounded to one maximal request per inference time (0.31-0.33 s here, 0.8-2.0 s on slower vCPUs per the specialists). With the 3 s semaphore wait plus a slow inference, requests approach the 10 s absolute deadline, at which point expire() closes the socket mid-inference and the model work is wasted.

  Setting intra_op_num_threads to the lease CPU count (2) is consistent with the design and roughly halves worst-case latency.

  whole finding

  Input: POST /v1/embeddings with 16 strings that each truncate to 256 tokens (body 29,655 bytes) and a valid ticket, process pinned with taskset -c 0,1.

  Expected for a 2-CPU lease: both CPUs used by one inference.

  Actual (measured here): 3 sequential maximal requests in 0.92 s with one core busy (0.31 s each); peak RSS 363 MiB; 12 concurrent maximal requests from distinct principals drive other principals to 429 (see the fairness finding).

The release under review is sha256:364adafb... with image digest sha256:bcb0a279..., build bfdb7c75... and profile claus-runtime-image-v1; none of these appear anywhere in the tree.

  The same client also posts to /v1/search with no Authorization header (network-access.ts json() with token undefined), whereas this image requires Authorization: Claus on both POST routes.

  Approving and running the reviewed release therefore does not make it reachable through the native network_semantic_search tool until this constant block and the request path are updated and re-reviewed, and the client that will actually mint tickets, hash bodies and batch documents for this release is not in the repository, so its sizing and error handling could not be audited. Operational consistency note; no code in the container depends on it.

• 11.infoTrust assumption: the operator Ed25519 key signs two protocols, and archive manifests carry no domain prefixsrc/portability/index.mjs:218

          const signature = sign(null, Buffer.from(canonical(manifest)), key).toString('base64');

  The image trusts the operator public key in admission-key.json (it equals the first operator key in docs/operators.json). The same signing key signs search-admission tickets with the prefix claus-semantic-admission/1\n (src/discovery/admission.mjs line 32) and project archive manifests with no prefix at all.

  Cross-protocol forgery is impossible at this commit only because canonical(manifest) always begins with "{" while a ticket message begins with "c", and because these are the only two sign() call sites. Any future unprefixed use of this key over attacker-influenced bytes would let that signature be presented to the model as a ticket. Recorded as a trust assumption; adding a domain prefix on the archive side removes the dependence on JSON shape.

  Not exploitable at this commit. Check: grep for "sign(null" across src, runtime, interfaces, adapters, api and reference returns exactly src/discovery/admission.mjs:32 and src/portability/index.mjs:218; canonical() returns "{"-prefixed text for objects, so no signed archive message can equal DOMAIN + ticket JSON.

2. Audit economicsAgent #1023found 1 info

   Review complete. The findings file at .imd-findings.json holds one info-level coverage finding and no medium, high or critical defects.

   Scope covered in depth (Economic Security, Invariant and Flow Gap passes, plus the validation gates):

   • ClausDealEscrow and ClausTokenDealEscrow: full deal and plan lifecycles, every settlement path, the arbiter resolution signature, the custody ceiling, withdrawal and the strict token balance deltas.
   • ClausNativeVault with ClausVaultAdmission and ClausReadonlyProject: principal conservation, forced ETH, policy failure modes.
   • ClausProjectWallet: session limits, generation renewal, nonce and quote replay, failed payouts.
   • ClausCapitalEscrow: by reading only, since it is not in the compiled tree.
   • The container application's economics: the ticket issuer token bucket in src/discovery/admission.mjs, the service-side admission in examples/semantic-search/admission.py and server.py, the pinned Dockerfile and model lock, and the off-chain arbitration and prepaid credit ledgers.
   • The existing suite of 83 Foundry tests passes on this commit.

   What I found. The invariants hold on every path I traced: escrow balance always covers locked plus credits, plan budgets flow into deals without double counting, deal and plan identifiers cannot collide or be squatted, and the review, dispute and expiry windows are mutually exclusive at their boundaries. Reentrancy during withdrawal cannot corrupt accounting in either escrow. The arbitration worker signs only within the on-chain resolution window with a one-hour margin.

   Retained risks that are documented, so not reported as defects:

   • A dispute that receives no arbiter signature within three days refunds the buyer in full. The docs call this a provider risk.
   • Idle withdrawable credits count against the custody ceiling, so parked credits can block new funding. Both the code comment and the docs state this.
   • The CLAUS token is an upgradeable proxy whose admin is the same key as the escrow admission controller. A token upgrade could block escrow withdrawals. The deployment record states this.
   • The semantic-search service rejects all callers once its bounded replay or caller maps fill. Its README states that bounded maps reject rather than evict.

   The one finding. contracts/ClausCapitalEscrow.sol is outside contracts/src, has no tests, is absent from the source manifest, and its exact pragma cannot build under the pinned compiler. Its value flows looked correct on reading, but nothing in the repository checks them.

   Coverage gaps. I did not run the Python service or the Node application. The broader Node codebase beyond the deal, admission and credit modules was not reviewed. No approval marker is emitted; that decision belongs to the final judge.

     Its exact pragma 0.8.26 also conflicts with the profile's pinned solc_version = "0.8.27", so it cannot be compiled by the project toolchain even if moved into src/. No test covers fund/release/refund, the EIP-712 release signature, the receiveWithAuthorization nonce binding or the mode-1 atomic delivery path.

     The economic review of this file is therefore by reading only; its value-flow invariants (USDC in == amount; mode 1 pays only after delivery balance delta == deliveryAmount; mode 0 release-before-expiry / refund-at-or-after-expiry are mutually exclusive) were checked manually and no defect was found, but none of that is enforced by the repository's checks. This is a coverage gap, not an exploit.

     whole finding

     From contracts/: copy ClausCapitalEscrow.sol into test/scratch/ and run forge build --contracts test/scratch/<copy>.sol.

     Expected: the file compiles and is part of the reviewed build.

     Actual: `Error: Encountered invalid compiler version ...

     No compiler version exists that matches the version requirement: =0.8.26. forge test` (83 tests) reports no suite for this contract; SOURCE_MANIFEST.json lists no hash for it.

3. Audit permissionsAgent #558found 2 medium, 1 low, 4 info

   The review is complete and the findings file is written at the repository root. No tracked files were changed.

   What was reviewed. The container application is the semantic-search service under examples/semantic-search, built from the pinned Dockerfile and called through tickets minted by the network issuer. I read the Dockerfile, asset lock, fetch script, server, admission verifier, key file, README and tests, then followed the trust chain into the issuer, the identity and authorization model, the HTTP auth layer, the rate-limit defaults, and the second use of the operator signing key. I ran the service locally with the pinned wheels and model. Its own suite passes 12 of 12, including SIGTERM drain, and I added probes for admission edge cases, worker-pool exhaustion and inference saturation.

   Findings written to .imd-findings.json:

   • Medium: per-principal fairness defeated by free agent principals. Inference is strictly serialized with a 3 s wait. Fairness is per sub, but one owner can mint 320 agent principals at no cost, each with a full allowance at the issuer and the model. Measured locally: 4 agents push a legitimate caller to a 2.3 s median wait, 8 agents produce 429 inference_busy failures.
   • Medium: health check starved by anonymous idle connections. Every accepted connection takes one of 24 worker slots before any byte is read. 24 idle sockets, renewed every 5 s, make GET /health close with no response. Measured locally.
   • Low: shared first-time-caller table. The 2048-entry table is shared across owners, so about 2240 free agent principals can refuse every new principal for 60 s.
   • Info: the operator key signs archive manifests without a domain prefix, so protocol separation rests on canonical JSON starting with a brace. The network-side tool pins a different release and image than this build. The Debian pool URLs are hash-checked but not immutable. A coverage statement lists verified properties and gaps.

   Verified clean within the assigned area. Signature verification before parsing, exact claim set, path and body binding, one-use nonces, strict Content-Length, no transfer-encoding, no input logging, unprivileged UID, no runtime network client or writes, all downloads pinned by digest and re-checked at startup. The CPU-only single-threaded model fits the 2 CPU, 4096 MiB, no-GPU manifest.

   Not covered. The registry image digest could not be pulled or compared here, the base-image tag was not resolved, and the remaining roughly 600 source files outside the identity, access, discovery and portability modules were not reviewed. No Solidity findings are claimed. Because two medium findings are open and the image binding could not be independently checked, the approval marker is not warranted.

   • mediumPer-principal fairness is defeated: free owner-minted agent principals saturate the single inference slot and other principals get 429examples/semantic-search/server.py:53

     The service runs one model inference at a time (BoundedSemaphore(1)) and any other admitted request waits at most 3 s before failing with 429 inference_busy. Its only fairness control is per principal: one active request per sub and a 120-burst / 2-per-second allowance (admission.py lines 67-72), mirrored by the issuer in src/discovery/admission.mjs.

     But the issuer binds sub to credential.principalId, and a project owner can mint agent principals for free: 32 agents per project (src/identity/index.mjs line 246) across 10 projects per owner, each with its own mandate and credential and each carrying service.call. Every agent is a distinct sub with its own full allowance at both the issuer and the model.

     A maximum-size request (16 texts x 2048 chars, truncated to 256 tokens each) occupies the inference lock for roughly 0.76-0.95 s single-threaded on this reviewer's machine, and longer on the 2-CPU target. With k agent principals keeping one max-size request in flight each, a legitimate principal waits behind up to k inferences; at k>=4 the median wait is already ~2.3 s and at k>=8 it hits the 3 s cutoff and requests fail with 429.

     The README's isolation claim ('Multiple credentials or projects do not create separate capacity for the same principal') holds per principal but not per owner, which is the actor that actually controls the agents. Issuer-side cost is small: the attacker needs ~8 tickets/s, within the global 3000-per-5-minute cap (src/access/index.mjs line 14), and the per-peer 300-per-5-minute cap only forces the tickets to be minted from ~8 source addresses. No funds are needed.

     This is an access x asymmetry trust gap: the authorization path (owner -> agent mandate with service.call) is legitimate, and the capacity formula is correct per sub, but the pairing lets one owner take a k-fold share of a strictly serialized resource and deny it to everyone else.

     Fix options that preserve the design: key admission capacity (and the active-request limit) at the model by the owner/project that minted the principal (the issuer knows mandate.ownerId and can put it in the ticket), or add a global in-flight queue cap with FIFO fairness so a principal never waits behind more than N other inferences, or lower the per-request cost ceiling (smaller batch/token budget) so a single slot cannot be held for ~1 s.

     whole finding

     State: one owner identity with one project; create 8 agents (identity.createAgent), grant each a mandate with scope service.call, issue a credential per agent.

     Input: each agent loops POST /v1/embeddings with body {"input": [16 strings of ~2030 chars]} and a fresh ticket for that body.

     Expected (README): other principals keep getting served because capacity is per principal and each principal has one active request.

     Actual (measured locally against the pinned model, test harness: Server with Admission(test key), 8 attacker threads each with its own sub, 1 legitimate thread posting a short text every 0.5 s for 20 s): with 4 attackers the legitimate principal's median latency is 2.29 s (all 200); with 8 attackers the legitimate principal receives 429 inference_busy on 2 of 6 requests with median latency 3.00 s, while each attacker still completes 6-7 requests.

     Max-batch inference measured at 0.76-0.95 s per call; single short text 0.001-0.002 s.

   • mediumHealth endpoint and admitted requests share a 24-connection pool that anonymous idle connections exhaust before any admission check; excess connections are dropped without a responseexamples/semantic-search/server.py:88

     process_request takes one of 24 worker slots for every accepted TCP connection before a single byte is read, so anonymous connections that never send a request consume the same budget as authenticated POSTs and as the orchestrator's GET /health. A connection that sends nothing holds its slot until the 5 s socket timeout in Handler.setup (line 126) fires (the absolute 10 s deadline is the upper bound).

     When all 24 slots are held, the 25th connection, including the platform health check at the manifest's healthPath, is closed immediately with no HTTP response at all (not a 429/503), so the health check fails with a reset. Keeping the pool full needs only ~5 new idle connections per second from one source, no account and no ticket.

     The manifest binds liveness to /health, so sustained failure removes the instance from service and can cause restarts, which also clear the in-memory replay table the README relies on. The README disclaims 'unlimited load' DDoS protection, but this is an application-level cap, not host capacity, and it is reachable at trivial rates.

     Fix preserving the design: do not charge pre-admission connections against the same pool as admitted work (for example a short dedicated pre-read deadline of ~1 s before any header arrives, a separate larger accept budget for anonymous connections, or serve /health from a reserved slot), and answer surplus connections with a 503 so health probes can distinguish overload from a dead process.

     whole finding

     Input: open 24 TCP connections to port 8080 and send nothing; 0.3 s later issue GET /health from another connection.

     Expected: 200 {"status":"ok",...} (health is documented as public and the connections carry no request).

     Actual (measured locally against the pinned code): the health request fails with RemoteDisconnected 'Remote end closed connection without response'; the 24 idle sockets are closed by the server about 4.7 s later and only then does GET /health return 200 again.

     Repeating the 24-connection batch every ~4.5 s keeps /health failing indefinitely.

   • lowShared first-time-caller table (2048) lets one owner's free agent principals lock out every new principal with 503 admission_capacityexamples/semantic-search/admission.py:65

     callers is keyed by sub and only evicts entries idle for 60 s; once it holds 2048 entries every principal not seen in the last 60 s is refused with 503 admission_capacity, while already-seen principals continue. Because agent principals are free and distinct subs (32 per project x 10 projects per owner, src/identity/index.mjs line 246), seven owner wallets can hold 2240 agent credentials and present one ticket each within 60 s.

     That is 2048+ successful begin() calls, which fits under the issuer's global 3000-per-5-minute cap (src/access/index.mjs line 14) when spread over ~7 source addresses for the 300-per-peer cap; the tickets can even carry a body that fails validation (e.g. {"input":[]}) so no inference is spent.

     Result: every first-time principal is refused for the following 60 s. Sustaining it needs 2048 tickets/minute, above the issuer's 600/minute average, so the outage is ~1 minute per 5-minute window rather than permanent. The README describes the bounded tables as a deliberate choice; the gap is that the bound is shared across owners while the thing that fills it is minted per owner for free.

     Keying the table by owner/project of the ticket, or making the issuer carry the owner in the claims and bounding entries per owner, closes it without changing the design.

     whole finding

     State: 7 owner identities, 10 projects each, 32 agents per project with service.call mandates and credentials (2240 subs).

     Input: within 60 s each sub POSTs /v1/search once with a valid ticket.

     Then a fresh principal P (never seen by this instance) POSTs /v1/search with a valid ticket.

     Expected: P is admitted (its own allowance is untouched).

     Actual: begin() raises AdmissionError(503,'admission_capacity') for P until 60 s after the attackers' last ticket; attackers' subs, already in callers, continue to be admitted.

     Unit-level check: construct Admission(CONFIG), call begin() for 2048 distinct subjects, then begin() for subject 'fresh' -> 503.

   • infoOperator Ed25519 key signs two protocols; archive manifests are unprefixed and separation relies on canonical JSON starting with "{"src/portability/index.mjs:218

     The image trusts the operator public key in admission-key.json (it matches the first operator in docs/operators.json). The same CLAUS_ARCHIVE_SIGNING_KEY signs search-admission tickets with the prefix 'claus-semantic-admission/1\n' (src/discovery/admission.mjs line 32) and project archive manifests with no prefix at all.

     Cross-protocol forgery is currently impossible only because canonical(manifest) always begins with '{' while a ticket message begins with 'c', and because no other sign() call site exists in src/, runtime/, interfaces/, adapters/ or api/. Any future unprefixed use of this key over attacker-influenced bytes would let a signature over those bytes be presented to the model as a ticket.

     Record as a trust assumption; adding a domain prefix on the archive side removes the dependency on JSON shape.

     Not exploitable at this commit. Check: grep for sign(null in the tree shows exactly two call sites; canonical() returns '{'-prefixed text for objects, so no signed archive message can equal DOMAIN + ticket JSON.

   • infoThe network-side semantic search tool pins a different release and image than the build under reviewreference/native-operations/src/network-semantic-search.ts:4

     The native read_network operation only talks to the model when the approved release, project, image and runpod resource match hard-coded values. Those values (releaseId sha256:ea3b4e5f..., image claus/dcd63b69...@sha256:b3faaf7c...) differ from this review's runtime context (releaseId sha256:364adafb..., image claus/bfdb7c75...@sha256:bcb0a279...).

     Approving this release does not make the pinned tool use it; the tool must be updated and re-pinned, and until then the network tool would report semantic_search_release_not_approved against this build. Reported so the asymmetry between the reviewed artifact and its consumer is explicit.

     Compare the runtime context releaseId/image in the review input with semanticSearchRelease in this file; semanticSearchEndpoint() throws 'semantic_search_release_not_approved' for approval.releaseId !== 'sha256:ea3b4e5f...'.

   • infoBuild-time downloads are hash-pinned but the Debian pool URLs are not immutable; a superseded package version will make the pinned build unreproducibleexamples/semantic-search/model-lock.json:77

     fetch_assets.py verifies exact size and SHA-256 for every model file, wheel and .deb, so substitution is detected (verified: all 12 assets fetched and matched during this review). The PyPI and Hugging Face commit URLs are content-stable, but deb.debian.org/debian/pool keeps only current package versions; when gcc-12 receives a point update these two URLs will 404 and the build stage fails. Availability-of-reproduction only; no integrity impact.

     Mirror the two .deb files under a stable snapshot URL (snapshot.debian.org) or vendor them.

     Expected: the pinned Dockerfile rebuilds indefinitely. Actual once libstdc++6/libgomp1 12.2.0-14+deb12u1 is superseded in the pool: urlopen() raises HTTP 404 in fetch_assets.py and docker build fails; the hash check never runs.

   • infoCoverage statement and resource-suitability assessment for this reviewexamples/semantic-search/Dockerfile:1

     Reviewed in depth: examples/semantic-search (Dockerfile, model-lock.json, fetch_assets.py, server.py, admission.py, admission-key.json, README, test_service.py), the issuer path src/discovery/admission.mjs, the identity/authorization model in src/identity/index.mjs, HTTP auth and rate limiting in interfaces/http.mjs and runtime/server.mjs, src/access defaults, and the second signing use in src/portability/index.mjs.

     Executed: the pinned test suite (12/12 pass with the pinned wheels and model, including SIGTERM drain), plus probes for admission edge cases, worker-pool exhaustion and inference saturation.

     Verified properties: Ed25519 verification with domain prefix before JSON parsing; exact claim set, aud, path, 20 s window, body hash bound and re-checked after read; one-use nonces; tickets consumed on body mismatch or validation failure (by design); no transfer-encoding, strict Content-Length <= 64 KiB; no logging of inputs; unprivileged UID 10001 with read-only use of root-owned files; no runtime network client, secrets, volumes or writes (PYTHONDONTWRITEBYTECODE=1, storageGiB 0 is consistent); base image, wheels, model and .deb pinned by digest/SHA-256 and checked for size; model integrity re-checked at startup; CPU-only ONNX Runtime with single-threaded inference, 24 HTTP threads and a 23 MB quantized model fit 2 CPU / 4096 MiB / no GPU (one core does inference, the second serves HTTP).

     SIGTERM stops accepting and drains in-flight requests under the 10 s deadline.

     Not covered: the registry image digest sha256:bcb0a279... could not be pulled or compared against a local build (no Docker here), so the receipt binding is taken from the task context; the base-image digest's tag was not resolved; onnxruntime's import without its declared pip dependencies was only confirmed on this x86_64 host, not inside the image; the remaining ~600 source files of the repository (contracts/, src/* outside identity/access/discovery/portability, hosting/, worker/, reference/) were not reviewed; no Solidity findings are claimed.

     Agent principal minting limits were read from src/access/index.mjs defaults, not from the live policy.

4. Audit flowAgent #460found 1 medium, 1 low, 4 info

   The review is complete. Six findings are recorded in .imd-findings.json, one medium, one low, four informational. No repository file was modified.

   What was audited. The container is the semantic-search model service under examples/semantic-search: its Dockerfile, lock file, build-time fetcher, admission verifier, HTTP server and test suite, plus the ticket issuer in src/discovery/admission.mjs, the manifest validator, the runtime-release approval rules, the build-plan Dockerfile binding, and the OCI workflow and runner config. I resolved the pinned base digest on Docker Hub (python 3.12.15 slim-bookworm, amd64 only), downloaded all twelve pinned assets and confirmed every size and SHA-256, installed the exact wheels with no other packages present, and ran the shipped twelve-test suite against the real model. All tests pass. The public key baked into the image equals the operator key in docs, and the issuer's claim shape matches the verifier.

   Findings

   • Medium: health check starved by idle anonymous sockets. Every accepted TCP connection takes one of 24 worker slots before any byte is read, and /health shares that pool. From one host, 24 idle connections make every health probe fail. Measured against the real entrypoint, 14 of 18 probes failed over 12 seconds while the sockets were refreshed, and authenticated requests are refused in the same window. The orchestrator will see the instance as down. The README disclaims flood-type load, but this needs no load at all.
   • Low: 2048-principal admission map. A farm of distinct network principals, each minting one ticket within 60 seconds, makes the service answer 503 to any principal not already seen. Existing callers are unaffected.
   • Info: version disclosure. Responses carry the stdlib Server: BaseHTTP/0.6 Python/3.12.x header and HTML error pages for unsupported methods.
   • Info: resource fit. CPU-only provider, peak RSS about 450 MiB, no disk writes, non-root UID, clean SIGTERM drain. All consistent with 2 CPU, no GPU, 4096 MiB, 0 GiB storage. Inference is pinned to one thread, so a maximal 16-text request takes about 2 seconds and 24 concurrent maximal requests yield 21 refusals. Using both leased CPUs would roughly halve latency.
   • Info: reference consumer pins the previous release. The native semantic-search consumer in reference/ hardcodes the earlier release and image digest, so it will reject the release under review until updated.
   • Info: coverage. The container application, its issuer and the infrastructure code named above were read in full. The remaining roughly one thousand repository files were not reviewed. No Docker daemon was available, so the image itself was not built; the dpkg extraction and library path override were reviewed by reading.

   What was not found. No secret in the image, no runtime download, no writable state, no SSRF surface, no host mount, privileged mode or volume reference, and no tenant-isolation break in the ticket protocol. Because one medium finding is open, the approval marker should not be issued for this release as it stands.

   • mediumHealth check and all inference share one 24-slot worker pool that idle, unauthenticated TCP connections exhaustexamples/semantic-search/server.py:88

     Server.process_request takes one of the 24 worker slots for every accepted TCP connection before a single byte has been read, and only releases it when the handler thread exits. Handler.setup sets a 5-second socket timeout, so a connection that never sends a request line holds its slot for 5 s (10 s if bytes are dripped, via the absolute deadline).

     GET /health is served from the same pool: once 24 slots are taken, process_request closes every new connection immediately, including the orchestrator's health probe. The manifest for this release declares healthPath /health, so the orchestrator sees the instance as down and will restart or deschedule it; each restart also clears the in-memory replay table.

     No ticket, signature or body is needed for this; the README's statement that anonymous connections share finite network capacity describes load, whereas this needs only 24 idle sockets from one host, refreshed every few seconds.

     Fix options that preserve the design: do not consume a bounded worker slot until a request line has arrived (accept, peek with a short 1 s timeout, then admit), reserve slots that only /health may use, or answer /health from a separate listener/thread outside the bounded pool; a shorter pre-request-line timeout (1 s instead of 5 s) further shrinks the window.

     whole finding

     State: server running as shipped (CMD python server.py).

     Input: from one client, open 24 TCP connections to port 8080 and send nothing, then issue GET /health with a 2 s timeout every 0.5 s.

     Expected: /health keeps returning 200 while the idle connections wait, or the idle connections are dropped before they can block the health path.

     Actual (measured with the Server/Handler classes from this file, model loaded): every /health attempt fails with RemoteDisconnected for the first ~4 s (until the 5 s socket timeout frees the slots), and when the 24 idle connections are re-opened every ~4 s, 18 of 18 health probes over 9 s failed; after the idle sockets were closed /health returned 200 again.

     Authenticated POSTs are refused the same way during the window because process_request rejects them before admission runs.

     Repeated against the real entrypoint (python server.py as a subprocess with the shipped admission key, PORT=18931): baseline /health 200; with 24 idle sockets re-opened every ~3.5 s, 14 of 18 health probes over 12 s failed; 200 again 5.5 s after the sockets were closed.

   • lowGlobal 2048-principal admission map lets a principal farm lock out every new caller for 60 s at a timeexamples/semantic-search/admission.py:65

     Admission.begin keeps one entry per distinct ticket subject (the network principal id) and refuses any principal it has not seen before with 503 admission_capacity once 2048 entries exist. Entries are only dropped after 60 s of inactivity (or never, while active).

     A single actor who controls many network principals (wallet-signed identities are free to create, each needing only service.call on its own project) can therefore mint one valid ticket per principal within a 60 s window and make the service answer 503 to any principal that has not already been admitted on this instance, including the Claus operator's own semantic-search caller after a restart.

     Already-admitted principals are unaffected, so the README's statement that capacity rejection never evicts live protection holds, but the 503 is a cross-tenant availability effect that the README does not describe.

     A minimal fix is to make the new-principal limit per time rather than per table size (e.g. cap distinct new subjects admitted per minute and expire idle entries sooner), or to key capacity by a larger bound than the 4096 replay table so that the replay table, not the caller table, is the first limit.

     whole finding

     State: fresh Admission with the service's key.

     Input: 2048 valid tickets with distinct sub values (sub0..sub2047), each admitted and finished within 60 s, then one valid ticket for a sub not seen before.

     Expected: the newcomer is admitted (it has its own untouched 120-token allowance).

     Actual (measured against this file): begin raises AdmissionError(503, 'admission_capacity') for the newcomer while a ticket for an existing sub (sub5) is still admitted; the lockout persists until 60 s have elapsed since the farm's last admission and is renewable by re-issuing one ticket per farmed principal.

   • infoResponses disclose the Python runtime version through the stdlib Server header and default HTML error pagesexamples/semantic-search/server.py:133

     Handler.reply calls BaseHTTPRequestHandler.send_response, which emits Server: BaseHTTP/0.6 Python/3.12.x and Date headers on every response, including the public /health endpoint. Unsupported methods and malformed request lines fall through to the stdlib send_error path, which returns text/html error pages (Error code: 501 Unsupported method ('PUT')) rather than the service's JSON shape.

     Neither leaks secrets, but the exact interpreter version in the pinned image is advertised to anonymous clients.

     Fix: set server_version/sys_version (or override version_string) on Handler and set error_message_format/error_content_type to a JSON body.

     Input: GET /health, or PUT /v1/embeddings, from an anonymous client.

     Expected: no interpreter version in the response headers and a JSON error body for unsupported methods.

     Actual (measured): 'Server: BaseHTTP/0.6 Python/3.12.3' on the 200 reply, and for PUT a 501 with Content-Type text/html;charset=utf-8 and the stdlib HTML error page.

   • infoResource fit for the 2-CPU, no-GPU lease: single-threaded inference leaves one CPU idle and bounds worst-case throughput to about one maximal request per 2 sexamples/semantic-search/server.py:41

     Suitability assessment, not a defect. The application matches the manifest: CPU-only onnxruntime provider (gpu null is correct), peak RSS measured at about 450 MiB against the 4096 MiB allowance, nothing written to disk (storageGiB 0 is correct, PYTHONDONTWRITEBYTECODE=1, UID 10001 cannot write /app), one listening port 8080, /health answers immediately after the 0.3 s model load, and SIGTERM drains within the 10 s connection deadline.

     However intra_op_num_threads=1 with a single inference permit means the second CPU of the lease is never used for inference. A maximal request (16 texts truncated to 256 tokens) took 1.8-2.0 s on one thread here; with the 3 s wait on the inference semaphore, 24 concurrent maximal requests from distinct principals produced 3 x 200 and 21 x 429 inference_busy, and every 429 also consumed the caller's one-use ticket.

     On a slower cloud vCPU the 3 s wait plus a 2-4 s inference approaches the 10 s absolute connection deadline, at which point expire() closes the socket mid-inference and the model work is wasted. Setting intra_op_num_threads to the lease's CPU count (2) is consistent with the design and roughly halves worst-case latency.

     whole finding

     Input: POST /v1/embeddings with 16 strings of 2048 dense ASCII characters (each tokenizes to >256 tokens, body ~33 KiB) with a valid ticket, pinned to two CPUs with taskset -c 0,1.

     Expected for a 2-CPU lease: both CPUs used by the single inference.

     Actual: latency 1.79-2.04 s per request with one core busy; 24 such requests at once from 24 principals: 3 succeed, 21 receive 429 inference_busy within 5.7 s.

Those constants name release sha256:ea3b4e5f... and image digest sha256:b3faaf7c..., while the release under review is sha256:364adafb... with image digest sha256:bcb0a279... and build bfdb7c75..., none of which appear anywhere in the tree.

     Approving and running the reviewed release therefore does not make it reachable through Claus's native network_semantic_search until this reference constant block is updated and re-reviewed; the operator's own approval check will throw semantic_search_release_not_approved. This is an operational consistency note about the consumer in reference/, not a defect in the container, and no code in the container depends on it.

     State: approval record {approved:true, releaseId:'sha256:364adafb90e97ca36af0934596a90e3e20cd069e1937c9d803b4ed61ae646fca', projectId:'prj_de70d4aa-0804-4a94-8097-7a9a34f0a28a', image:'claus-network-api.vercel.app/claus/bfdb7c75...@sha256:bcb0a279...'} for a running resource.

     Expected: semanticSearchEndpoint returns the runpod endpoint.

     Actual: it throws Error('semantic_search_release_not_approved') because approval.releaseId !== semanticSearchRelease.releaseId.

   • infoCoverage statement: container application fully read and exercised; wider repository only partially coveredREADME.md:1

     Read in full and tested: examples/semantic-search (Dockerfile, model-lock.json, fetch_assets.py, admission.py, server.py, admission-key.json, test_service.py, README, LICENSE), the ticket issuer src/discovery/admission.mjs and test/search-admission.test.mjs, src/infrastructure/manifest.mjs, src/infrastructure/runtime-release.mjs (requirement lines), src/infrastructure/build-plan.mjs (Dockerfile binding), .github/workflows/claus-oci.yml and config/oci-runner.json.

     Verified externally: the pinned base digest resolves on Docker Hub to a single-platform linux/amd64 python 3.12.15 slim-bookworm image (config digest 4f228bc1..., 4 layers, ~47.6 MB compressed); all 12 pinned downloads (4 model files, 6 wheels, 2 Debian packages) match the lock's size and SHA-256; the exact wheels installed with --no-deps import cleanly with no other packages present, and the shipped 12-test suite passes against the real model.

     Public key in admission-key.json equals the operator key in docs/operators.json; ticket claim shapes match between issuer and verifier; principal ids (usr_ + hex) satisfy the verifier's sub pattern.

     Not covered: the remaining ~1000 files of the repository (network core, adapters, runtime workers, contracts, reference implementations) beyond the paths named above; no Docker daemon was available so the image itself was not built, and the build-time dpkg-deb extraction and LD_LIBRARY_PATH override were reviewed by reading only. No host credential, host mount, privileged mode or persistent volume is referenced by the Dockerfile or server; the image sets USER 10001:10001.

5. Audit mathAgent #354found 3 low, 2 info

   The review is complete and the findings file is written and validated against the tree.

   Outcome. No medium, high or critical defects were found in the container application. Three low findings and two coverage notes are in .imd-findings.json. Nothing in the repository was modified, and the working tree is clean.

   What I verified in depth (math, boundary and numerical-gap passes on the container):

   • Ran the service's own 12 tests with the pinned numpy, onnxruntime, tokenizers and cryptography versions and the pinned model files, all passing.
   • Drove the admission module with injected clocks: the 120-token bucket drains at the 121st request, refills at one token per 0.5 s, rejections do not move the refill clock, and a 60 s idle period resets to a full bucket consistently with the prune rule.
   • Checked the ticket time edges (iat up to now+2000 ms accepted, now+2001 rejected; exp boundary), header length at the maximum subject size, Content-Length parsing, batch and limit ranges, pooling and normalization floors, and cosine scores for identical texts (1.0000000064, inside the client tolerance).
   • Measured resource fit: 1.1 s for a full 16-text batch on one thread, under 400 MiB resident with 8 concurrent batches. The 2 vCPU, 4 GiB, no-GPU, no-storage manifest is adequate.

   Findings written:

   • Low: a lone-surrogate text makes the tokenizer raise TypeError, which the server reports as 503 instead of 400, consuming the ticket and a token.
   • Low: the replay table is pruned by wall-clock time, so a clock step forward then back re-admits a used ticket. Needs a host clock change.
   • Low: the in-tree client packs 15 documents by UTF-16 length while the service caps bodies at 64 KiB bytes. Eleven CJK-heavy documents produce a 68 KB body and a 413 that aborts the whole search.
   • Info: the only client in the tree sends no admission ticket and pins a different release and profile, so the live client for this release is not auditable here.
   • Info: the image digest and build could not be rebuilt without Docker, the runtime sourceHash does not match any subset of the example directory, the base image and archive size were not resolved, and the issuer key correspondence could not be checked from the tree.

   Because the image digest, source hash and the actual client remain unverified, I have not asserted the approval marker. That decision belongs to the final judge with those gaps in view.

   • lowUnencodable text (lone UTF-16 surrogate) is reported as a 503 server fault instead of a 400 client errorexamples/semantic-search/server.py:204

     Boundary: the tokenizers encode_batch call inside Engine.embed.

     Assumption: bad text raises ValueError/UnicodeError, which do_POST maps to 400.

     Actual: for a str that cannot be encoded as UTF-8 (a lone surrogate, which json.loads accepts from the JSON escape \ud800 and which passes the isinstance/strip/len checks), tokenizers 0.21.4 raises TypeError ('TextEncodeInput must be Union[TextInputSequence, Tuple[InputSequence, InputSequence]]'). TypeError is not in the 400 handler, so it falls through to the generic handler and is answered 503 inference_unavailable.

     The caller's malformed input is classified as a service outage, and the admitted one-use ticket plus one rate-limit token are consumed. The exception is raised while the single inference semaphore is held (released by finally, so no leak). Only a direct caller of the service can trigger it; catalogue text produced by the network passes sourceText().isWellFormed(), so the in-tree client cannot be made to send it by a third party.

     Verified against the pinned model.

     whole finding

     Input: POST /v1/embeddings with a valid ticket and body {"input":"a\ud800"} (well-formed JSON; json.loads yields 'a\ud800', length 2, passes validation).

     Expected: HTTP 400 with a client error code.

     Actual: Engine.embed -> tokenizer.encode_batch raises TypeError -> except Exception -> HTTP 503 {"error":"inference_unavailable"}.

     Same for /v1/search with such a document text or query.

     Reproduced locally with Engine().embed(['abc\ud800']) -> TypeError.

     Fix: in the validation branch of embed reject texts for which t.encode('utf-8') fails (or add TypeError to the 400 handler) before acquiring the inference lock.

   • lowReplay table is pruned by the wall clock, so a wall-clock step forward then back re-admits an already used ticketexamples/semantic-search/admission.py:60

     Seam boundary x invariant. Invariant (README): a ticket is accepted once per running instance. It is kept by self.used keyed on nonce and pruned when the stored exp is not greater than the current wall-clock millisecond.

     The expiry test and the prune both read self.clock (time.time), which is not monotonic, while the per-caller refill correctly uses time.monotonic. If the host wall clock steps forward past a ticket's exp (any later begin() call prunes the nonce) and then steps back into the ticket's window (NTP correction, VM clock resync), the same signed ticket passes the exp check again and its nonce is gone from self.used, so it is admitted a second time and consumes another inference.

     Requires a host clock change, not an unprivileged caller, hence low.

     State: Admission(config, clock=wall, monotonic=mono) with wall=1700000000.000.

     1. begin(T) for a valid ticket T (iat=now, exp=now+20000): admitted, used[nonce]=exp; finish(T).

     2. begin(T) again: 401 admission_used (correct).

     3. wall += 25 s, then any begin() call runs the prune: used[nonce] has exp <= now and is dropped.

     4. wall -= 25 s (back to the original second).

     5. begin(T): exp > now and nonce not in used.

     Expected: 401 admission_used.

     Actual: admitted (claims returned).

     Reproduced by driving the module with injected clocks exactly as above.

     Fix: store a monotonic expiry, e.g. used[nonce] = tick + (exp - now)/1000, and prune with v > tick.

   • lowClient packs 15 documents by UTF-16 length while the service caps the body in bytes, so a non-ASCII catalogue page fails the whole search with 413reference/native-operations/src/network-semantic-search.ts:46

     Seam boundary x precision between two scales. The client bounds each document to 2048 UTF-16 code units and sends 15 per request; the service (examples/semantic-search/server.py, MAX_BODY) bounds the request to 65536 bytes and answers 413 request_size_invalid before parsing. A character limit and a byte limit only agree for ASCII.

     Project descriptions are validated with sourceText (length <= 500 code units, well-formed, non-ASCII allowed), so a page of CJK-heavy project JSON (name, description, agents, services) produces documents of up to 6144 bytes each. Measured sizes with json serialisation: 15 documents x 2048 CJK chars = 93,316 bytes; 11 such documents = 68,325 bytes (> 65,536); 15 x 2048 ASCII = 31,876 bytes.

     When one batch exceeds the cap the service replies 413, json() throws network_request_failed and semanticNetworkSearch aborts for every caller of that page. Any project owner can publish such text, but the exact page composition (>= 11 heavy documents in the same 15-item window) is needed, so low.

     Note this client also sends no Authorization: Claus ticket and pins releaseId sha256:ea3b4e5f... / profile claus-runpod-cpu-v1, not the audited release, so it cannot be the live client for this image (see the coverage entry).

     whole finding

     State: a network_overview page whose 15-document window contains 11 projects each with text of 2048 three-byte characters (for example description and agent/service names in CJK); query 'q'; limit 5.

     The client builds body = JSON.stringify({query, documents: 15 x {id, text}, limit}) = 68,325 bytes for 11 heavy + 4 empty documents (93,316 bytes if all 15 are heavy).

     Expected: the client batches so that each request is within the service's documented 64 KiB body limit (for example by splitting on Buffer.byteLength), or truncates by bytes.

     Actual: server.py do_POST rejects with 413 {"error":"request_size_invalid"} because int(Content-Length) > 65536; the client throws and no results are returned.

     Fix: measure Buffer.byteLength of the serialised batch and split or shrink documents until it is <= 65536.

   • infoCoverage: no in-tree client speaks this release's admission protocol; the only integration posts without a ticket and pins another release and profilereference/native-operations/src/network-access.ts:74

     The container requires Authorization: Claus on both POST routes (admission.py). The only consumer in the tree calls json() with token undefined (no Authorization header), so against this image every call returns 401 admission_required; it also requires releaseId sha256:ea3b4e5f... and profileId claus-runpod-cpu-v1, whereas the runtime context under review is releaseId sha256:364adafb... with profile claus-runtime-image-v1.

     The issuer side (src/discovery/admission.mjs) is consistent with admission.py: Ed25519 over the same domain string, exp - iat = 20000, 32-hex nonce, 64-hex bodyHash, path in the allowed set, sub = principalId matching [A-Za-z0-9_:.-]{1,160}, and a 120 / 2-per-second bucket in integer milli-token units.

     The client that will actually mint tickets, hash bodies and batch documents for this release is not in the repository, so its request sizing and error handling could not be audited.

     whole finding

     Input: run the reference client's network_semantic_search against this image.

     Expected: a Claus ticket minted via POST /v1/projects/{projectId}/search-admission and a 200 ranking.

   • infoCoverage: image digest, source hash and base image were not reproduced; resource fit measured locallyexamples/semantic-search/Dockerfile:1

     What was verified: all 9 files of examples/semantic-search read; model-lock.json pins 4 model files, 6 wheels and 2 Debian packages by URL, size and SHA-256 and fetch_assets.py enforces both; the 4 model files were downloaded here and matched their pinned digests; Engine re-verifies size and SHA-256 of every model file at start; the service's own 12 tests pass with the pinned numpy 2.2.6 / onnxruntime 1.22.1 / tokenizers 0.21.4 / cryptography 50.0.2; runtime stage runs as UID 10001, writes nothing (PYTHONDONTWRITEBYTECODE, storageGiB 0 is adequate), has no outbound client, keys or secrets, listens on 8080 with /health public.

     Math checked with concrete inputs: token bucket (121st request 429, refill 0.5 s per token, idle 60 s resets to 120, rejections do not move the refill clock), iat skew edge (now+2000 accepted, now+2001 rejected), exp edge, header length 635 <= 1800 at the 160-char sub maximum, Content-Length digit/width/range checks, 1..16 texts, 1..15 documents, limit 1..15, mean pooling with mask floor 1, norm floor 1e-12, finite check, cosine of identical texts 1.0000000064 (within the client tolerance 1.00001), 2048-char CJK/emoji/zero-width inputs all truncate to <= 256 tokens.

     Resource fit on this host: engine RSS 139 MiB after load, 256 MiB after one 16 x 256-token batch, 388 MiB with 8 concurrent batches; one 16 x 256 batch takes 1.1 s on one thread (OMP/ORT pinned to 1), so 2 vCPU / 4096 MiB / no GPU is adequate and the GPU-less manifest matches the CPU-only provider list.

     Not verified: (a) the registry image digest sha256:bcb0a279... and the build receipt could not be rebuilt (no Docker on this worker); (b) the runtime sourceHash sha256:8ee6795a... does not equal createOciBuildPlan's digest over any subset of the example directory tried (with or without README/LICENSE/test_service.py, with or without the examples/semantic-search/ prefix), so the snapshot that was built contains other files not identifiable from the tree; (c) the base image digest's Debian release and the final archive size were not resolved, and the standard public build lane caps archives at 32 MiB (src/infrastructure/builds.mjs) while the pinned model alone is 22.9 MB and the two large wheels 33 MB, so which lane produced the receipt could not be confirmed; (d) the issuer public key in admission-key.json (91OURUkw...) is the only copy in the tree and the signing key is an operator environment secret, so key correspondence was not checked; (e) 7 of the 12 catalogue passes (access control, economics, execution trace, invariants, periphery, asymmetry, trust/flow gaps) were applied only lightly to the container and the Solidity sources, which contain no division, fee or share arithmetic (only guarded add/sub and uint64 timestamp casts).

6. Audit judgeAgent #540found 2 medium, 4 low, 7 info

   The review is complete. The findings file is written and validated, and the working tree holds no stray files.

   Outcome: 13 findings in .imd-findings.json, all reproduced here against the code at the pinned commit. The approval marker is withheld because two medium findings remain unresolved.

   What I verified before judging. I built a Python 3.12.15 environment with the exact pinned wheel versions, installed them with the same no-dependencies flag the Dockerfile uses, downloaded the four pinned model files (sizes and SHA-256 matched), and ran the shipped 12-test suite, which passed in both environments. Every specialist finding was then re-run with its own script against the real server, admission module and model.

   Kept at medium:

   • Worker pool exhaustion of the health check. 24 idle TCP connections, no ticket needed, made every /health probe fail with a closed socket for about 3 seconds per batch, renewable indefinitely. Two specialists reported this; merged into one.
   • Per-owner saturation of the single inference slot. Twelve free agent principals from one owner, each keeping a maximal request in flight, pushed a legitimate principal to 3 s median latency and a 429 response on a 2-CPU pin.

   Kept at low: the 2048-subject admission lockout (merged from two specialists), the wall-clock replay re-admission, client-caused errors answered as 503 (I added a second input, deeply nested JSON, with the same root cause), and the reference client's UTF-16 versus byte sizing.

   Kept at info: interpreter version in the Server header, resource suitability for the 2-CPU lease, the reference consumer pinning the previous release and sending no ticket (three specialist entries merged), mutable Debian pool URLs, the shared operator signing key as a trust assumption, the escrow contract outside the Foundry tree (reproduced the compiler error), and one merged coverage statement.

   Dropped or merged: the four separate coverage entries became one. Nothing failed to reproduce. No critical or high findings exist, so no Foundry proofs were required.

   Not verifiable here: the registry image digest and build receipt could not be rebuilt without a Docker daemon, the runtime source hash was not reproduced from the tree, and the wider repository outside the paths named in the coverage statement was not re-audited.

   • mediumHealth check and all inference share one 24-slot worker pool that idle, unauthenticated TCP connections exhaust before any request is readexamples/semantic-search/server.py:88

     Server.process_request takes one of the 24 worker slots for every accepted TCP connection before a single byte has been read and releases it only when the handler thread exits. Handler.setup sets a 5 s socket timeout, so a connection that never sends a request line holds its slot for 5 s (up to the 10 s absolute deadline if bytes are dripped).

     GET /health, the manifest healthPath, is served from the same pool: once 24 slots are held, process_request calls shutdown_request on every new connection, which is closed with no HTTP response at all (not a 429 or 503). The orchestrator therefore sees the instance as down and will restart or deschedule it; each restart also clears the in-memory replay table. Keeping the pool full needs about 5 new idle connections per second from one source with no account or ticket.

     The README disclaims unlimited-load protection, but this is an application-level cap reachable at trivial rates, not host network capacity. Fix preserving the design: do not charge a slot until a request line has arrived (accept, read with a short ~1 s pre-header timeout, then admit), or reserve capacity that only /health can use (separate listener or reserved slot), and answer surplus connections with a 503 so the probe can distinguish overload from a dead process.

     Merged from two specialists (audit_flow, audit_permissions) reporting the same mechanism.

     whole finding

     State: Server/Handler from server.py with the real Engine and an Admission with a test key, serve_forever in a thread (the shipped test harness).

     Input: open 24 TCP connections to the port and send nothing; 0.3 s later issue GET /health with a 2 s timeout every 0.5 s.

     Expected: /health keeps returning 200 while the idle sockets wait.

     Actual (measured here): baseline /health 200; with the idle sockets open every probe at t=0.0, 0.5, 1.0, 1.5, 2.0, 2.5 s fails with RemoteDisconnected (server closed the socket without any response bytes; a raw 25th connection sending a complete GET /health received b''); probes return 200 again only from t=3.0 s, when the 5 s socket timeout in Handler.setup frees the slots.

     Re-opening the 24 sockets every ~4 s keeps the probe failing indefinitely.

     Admitted POSTs are refused the same way during the window because the slot check runs before admission.

   • mediumPer-principal fairness is defeated: one owner's free agent principals saturate the single inference slot and other principals get 429 inference_busyexamples/semantic-search/server.py:53

     The service runs one model inference at a time (BoundedSemaphore(1)); any other admitted request waits at most 3 s and then fails with 429 inference_busy, which also consumes the caller's one-use ticket and a rate token. The only fairness control is per principal (one active request per sub, 120 burst / 2 per second, admission.py lines 67-72, mirrored in src/discovery/admission.mjs).

     The issuer binds sub to credential.principalId, and a project owner can mint agent principals for free: ACCESS_DEFAULTS allows 32 agents per project and 10 projects per owner (src/access/index.mjs line 8, src/identity/index.mjs line 246), each with its own mandate carrying service.call and so its own full allowance at issuer and model.

     With k agents each keeping one maximum-size request (16 texts truncated to 256 tokens) in flight, every other principal waits behind up to k inferences. The README claim that multiple credentials or projects do not create separate capacity holds per principal but not per owner, which is the actor who controls the agents. Issuer cost is small (about 8-12 tickets/s, under the 3000-per-5-minute global cap; the 300-per-peer cap only spreads minting over a few source addresses).

     Fix options that keep the design: carry the owner or project id in the ticket and key the active-request limit and bucket by it at the model; or bound in-flight inference with a FIFO queue so no admitted request waits behind more than N others; or lower the per-request ceiling so one slot cannot be held for a full inference of maximal size.

     Expected (README): the legitimate principal keeps being served because capacity is per principal.

     Actual (measured here, a single max-size inference takes 0.31-0.33 s on this CPU): k=1 median latency 0.10 s, all 200; k=4 median 0.97 s, all 200; k=8 median 2.12 s, max 2.21 s, all 200; k=12 median 2.98 s, max 3.01 s, 1 of 4 legitimate requests 429 inference_busy; k=16 median 2.92 s, 1 of 4 requests 429.

     The attackers still complete 3-7 requests each.

     A slower vCPU (the specialist measured 0.76-0.95 s per max inference) reaches the 429 cutoff at k=8.

   • lowGlobal 2048-principal admission table lets one owner's free agent principals lock out every new principal with 503 admission_capacity for 60 s at a timeexamples/semantic-search/admission.py:65

     Admission.begin keeps one entry per distinct ticket subject and refuses any subject it has not seen with 503 admission_capacity once 2048 entries exist. Entries are dropped only after 60 s of inactivity.

     Agent principals are free and distinct subs (32 per project x 10 projects per owner, src/access/index.mjs line 8), so seven owner wallets hold 2240 agent credentials; presenting one valid ticket per agent within 60 s (the body may be one that fails validation, so no inference is spent) fills the table and every first-time principal, including the operator's own caller after a restart, is refused for the following 60 s.

     Already-admitted principals continue, so the README statement that capacity rejection never evicts live protection holds, but the cross-tenant 503 is not described. Sustaining it needs about 2048 tickets per minute, above the issuer's 600-per-minute average, so the outage is roughly one minute per five-minute window.

     Fix: key the table (or a per-owner sub-bound) by the owner/project the issuer puts in the ticket, or make the newcomer limit per unit time rather than per table size and expire idle entries sooner. Merged from two specialists (audit_flow, audit_permissions).

     Actual (measured here): begin() raises AdmissionError(503, "admission_capacity") for fresh, while a ticket for the existing sub5 is still admitted; after advancing the monotonic clock 61 s, fresh is admitted.

     The lockout is renewable by re-issuing one ticket per farmed principal within each 60 s window.

The per-caller refill correctly uses time.monotonic, but the replay prune and the exp check both use wall time.

     If the host wall clock steps forward past a ticket's exp, any later begin() call prunes the nonce; if the clock then steps back into the ticket's 20 s window (NTP correction, VM clock resync after migration), the same signed ticket passes the exp check again and its nonce is gone, so it is admitted a second time and consumes another inference. Requires a host clock change, not an unprivileged caller, hence low.

     Fix: store a monotonic expiry (used[nonce] = tick + (exp - now)/1000) and prune with v > tick, keeping the wall-clock exp check as is.

     State: Admission(CONFIG, clock=lambda: wall, monotonic=lambda: mono) with wall=1700000000.0, mono=1000.0.

     1. begin(T) for a valid ticket T (iat=now, exp=now+20000): admitted; finish(T).

     2. begin(T) again: AdmissionError 401 admission_used (correct).

     3. wall += 25, mono += 25; begin() for another sub runs the prune: used table shrinks to 1 entry (the new one), T's nonce is gone.

     4. wall -= 25 (back to the original second).

     5. begin(T).

     Expected: 401 admission_used.

     Actual (measured here): admitted, claims returned with T's nonce.

   • lowClient-caused failures inside the inference path (lone UTF-16 surrogate, deeply nested JSON) are answered 503 inference_unavailable instead of 400examples/semantic-search/server.py:204

     do_POST maps only ValueError and UnicodeError to 400; every other exception becomes 503 inference_unavailable.

     Two inputs a direct caller controls reach that branch: (a) a string that JSON allows but cannot be UTF-8 encoded (a lone surrogate from the escape \ud800) passes the isinstance/strip/len checks in Engine.embed and makes tokenizers 0.21.4 encode_batch raise TypeError while the single inference semaphore is held (it is released by finally, no leak); (b) a body of 60,000 opening brackets within the 64 KiB cap makes json.loads raise RecursionError.

     In both cases the caller's malformed input is classified as a service outage, and the admitted one-use ticket and one rate token are consumed. Only a direct caller can trigger these; catalogue text produced by the network passes a well-formedness check.

     Fix: reject texts for which t.encode("utf-8") fails in the validation branch of embed, and add TypeError and RecursionError to the 400 handler (or wrap json.loads).

     whole finding

     Input A: POST /v1/embeddings with a valid ticket and body {"input":"a\ud800"} (json.loads yields a 2-character str that passes validation).

     Expected: HTTP 400 with a client error code.

     Actual (measured here with the pinned model): Engine().embed(["a\ud800"]) raises TypeError("TextEncodeInput must be Union[...]"), which do_POST answers as 503 {"error":"inference_unavailable"}; engine.lock value is back to 1 afterwards.

     Input B: body of b"[" * 60000 with a matching bodyHash.

     Expected: 400 invalid_json.

     Actual: json.loads raises RecursionError, answered 503.

     Same for /v1/search document text or query.

   • lowReference client bounds documents by UTF-16 length while the service caps the body in bytes, so a non-ASCII catalogue page fails the whole search with 413reference/native-operations/src/network-semantic-search.ts:46

     semanticNetworkSearch truncates each document to 2048 UTF-16 code units and posts 15 per request; the service (server.py MAX_BODY) rejects any request whose Content-Length exceeds 65,536 bytes with 413 request_size_invalid before parsing. A character limit and a byte limit only agree for ASCII.

     Project descriptions are validated with prose(description, 500) (src/projects/index.mjs line 172), non-ASCII allowed, and agent and service names are serialised into the same text, so CJK-heavy projects produce documents of up to 6,144 bytes each. When a 15-document window contains 11 or more such documents the batch exceeds the cap, the service answers 413, json() throws and semanticNetworkSearch aborts for every caller of that page.

     Any project owner can publish such text, but the page composition is needed, so low. Note this client is not the live client for the audited image (see the consumer-mismatch finding).

     Fix: measure Buffer.byteLength of the serialised batch and split or shrink documents until it is at most 65,536 bytes.

     whole finding

     Input: a network_overview page whose 15-document window contains 11 projects each serialising to 2048 three-byte characters.

     The client builds JSON.stringify({query:"q", documents: 15 x {id, text}, limit:5}).

     Measured here with node: 15 heavy CJK documents = 93,157 bytes; 11 heavy + 4 empty = 68,581 bytes; 10 heavy = 62,437 bytes; 15 x 2048 ASCII = 31,717 bytes.

     Expected: the client batches so each request stays within the documented 64 KiB body limit.

     Actual: server.py do_POST line 164 rejects int(Content-Length) > 65536 with 413 {"error":"request_size_invalid"}; the client throws network_request_failed and no results are returned.

   • infoResponses disclose the interpreter version through the stdlib Server header and unsupported methods return the stdlib HTML error pageexamples/semantic-search/server.py:133

     Handler.reply calls BaseHTTPRequestHandler.send_response, which emits Server: BaseHTTP/0.6 Python/3.12.x and Date headers on every response including the public /health. Unsupported methods and malformed request lines fall through to the stdlib send_error path, which returns text/html rather than the service JSON shape. No secret leaks, but the exact interpreter version of the pinned image is advertised to anonymous clients.

     Fix: override version_string (or set server_version/sys_version) on Handler and set error_message_format/error_content_type to a JSON body.

     Input: GET /health, then a raw PUT /v1/embeddings, from an anonymous client.

     Expected: no interpreter version in response headers and a JSON error body for unsupported methods.

     Actual (measured here): "Server: BaseHTTP/0.6 Python/3.12.15" on the 200 reply; for PUT a "501 Unsupported method ('PUT')" response with Content-Type text/html;charset=utf-8 and a 356-byte HTML page.

   • infoResource suitability for the 2-CPU, no-GPU, 4096 MiB, no-storage lease: adequate, but single-threaded inference leaves the second CPU idleexamples/semantic-search/server.py:41

     Assessment, not a defect.

     The application matches the manifest: CPU-only onnxruntime provider (gpu null is correct); peak RSS measured here at 363 MiB after warm-up and three maximal batches against the 4096 MiB allowance; nothing is written at runtime (PYTHONDONTWRITEBYTECODE=1, UID 10001 cannot write /app, no volume) so storageGiB 0 is correct; one listening port 8080; /health answers immediately after the sub-second model load; SIGTERM stops accepting and drains within the 10 s connection deadline (shipped test passes).

     However intra_op_num_threads=1 together with a single inference permit means the second CPU of the lease is never used for inference; worst-case throughput is bounded to one maximal request per inference time (0.31-0.33 s here, 0.8-2.0 s on slower vCPUs per the specialists). With the 3 s semaphore wait plus a slow inference, requests approach the 10 s absolute deadline, at which point expire() closes the socket mid-inference and the model work is wasted.

     Setting intra_op_num_threads to the lease CPU count (2) is consistent with the design and roughly halves worst-case latency.

     whole finding

     Input: POST /v1/embeddings with 16 strings that each truncate to 256 tokens (body 29,655 bytes) and a valid ticket, process pinned with taskset -c 0,1.

     Expected for a 2-CPU lease: both CPUs used by one inference.

     Actual (measured here): 3 sequential maximal requests in 0.92 s with one core busy (0.31 s each); peak RSS 363 MiB; 12 concurrent maximal requests from distinct principals drive other principals to 429 (see the fairness finding).

   • infoThe only in-tree consumer pins the previous semantic-search release and profile and sends no admission ticket, so it cannot use the release under reviewreference/native-operations/src/network-semantic-search.ts:4

     semanticSearchEndpoint requires approval.releaseId, the running resource manifest.releaseHash and image to equal the constants in semanticSearchRelease (release sha256:ea3b4e5f..., image sha256:b3faaf7c..., profile claus-runpod-cpu-v1 at line 19). The release under review is sha256:364adafb... with image digest sha256:bcb0a279..., build bfdb7c75... and profile claus-runtime-image-v1; none of these appear anywhere in the tree.

     The same client also posts to /v1/search with no Authorization header (network-access.ts json() with token undefined), whereas this image requires Authorization: Claus on both POST routes.

     Approving and running the reviewed release therefore does not make it reachable through the native network_semantic_search tool until this constant block and the request path are updated and re-reviewed, and the client that will actually mint tickets, hash bodies and batch documents for this release is not in the repository, so its sizing and error handling could not be audited. Operational consistency note; no code in the container depends on it.

     Merged from three specialist entries (audit_flow, audit_math, audit_permissions).

     Expected: semanticSearchEndpoint returns the endpoint and a ranking is produced.

     Actual: it throws Error("semantic_search_release_not_approved") at line 14 because approval.releaseId !== semanticSearchRelease.releaseId; and even with matching constants, POST /v1/search without Authorization is answered 401 {"error":"admission_required"} by admission.begin(None, path).

   • infoBuild-time downloads are hash-pinned but the two Debian pool URLs are not immutable, so a superseded gcc-12 point release makes the pinned build unreproducibleexamples/semantic-search/model-lock.json:77

     fetch_assets.py verifies exact size and SHA-256 for every model file, wheel and .deb, so substitution is detected. The Hugging Face commit URLs and PyPI file URLs are content-stable, but deb.debian.org/debian/pool keeps only current package versions; when gcc-12 receives a point update these two URLs 404 and the build stage fails before any hash check runs. Availability of reproduction only, no integrity impact.

     Mirror the two .deb files from snapshot.debian.org or vendor them.

     Checked here: both URLs currently answer HTTP 200 and the pool directory lists exactly one libstdc++6 amd64 build (12.2.0-14+deb12u1).

     Expected: the pinned Dockerfile rebuilds indefinitely.

     Actual once that version is superseded: urlopen() in fetch_assets.py raises HTTP 404 and docker build fails; the SHA-256 check never runs.

   • infoTrust assumption: the operator Ed25519 key signs two protocols, and archive manifests carry no domain prefixsrc/portability/index.mjs:218

     The image trusts the operator public key in admission-key.json (it equals the first operator key in docs/operators.json). The same signing key signs search-admission tickets with the prefix claus-semantic-admission/1\n (src/discovery/admission.mjs line 32) and project archive manifests with no prefix at all.

     Cross-protocol forgery is impossible at this commit only because canonical(manifest) always begins with "{" while a ticket message begins with "c", and because these are the only two sign() call sites. Any future unprefixed use of this key over attacker-influenced bytes would let that signature be presented to the model as a ticket. Recorded as a trust assumption; adding a domain prefix on the archive side removes the dependence on JSON shape.

     Not exploitable at this commit. Check: grep for "sign(null" across src, runtime, interfaces, adapters, api and reference returns exactly src/discovery/admission.mjs:32 and src/portability/index.mjs:218; canonical() returns "{"-prefixed text for objects, so no signed archive message can equal DOMAIN + ticket JSON.

     contracts/ClausCapitalEscrow.sol (the Base USDC milestone / token-allocation escrow referenced by reference/capital-execution/src/capital/escrow.json and reference/review-evidence-payer/src/capital/escrow.json) is not under contracts/src, so forge build and forge test under contracts/foundry.toml never compile or exercise it, and SOURCE_MANIFEST.json lists no hash for it.

     Its exact pragma 0.8.26 also conflicts with the profile's pinned solc_version 0.8.27, so it cannot be compiled by the project toolchain even if moved. Coverage gap, not an exploit; its value-flow logic was reviewed by reading only.
