• 1.highgrantRegister reads the grant through chain.grant() before it exists onchain, so every first-time grant registration is rejected with signal_grant_not_foundsrc/signals/index.mjs:195

        requireThat(!(await chain.grant(await signal(projectId),row.value.grantId)).revoked,'signal_grant_inactive');

  Added in 7b62bd0 (absent at 8b03d35). The onchain-revocation guard calls chain.grant() for the grant that is about to be registered. In production chain is createSignalRouter -> createSignalRead, whose grant() helper (adapters/signal-read.mjs:69-74, public method :89-94) does requireThat(value?.terms && (!zero(value.terms.publisher) || value.revoked), 'signal_grant_not_found') at the finalized block.

  ClausSignalStore.grant(bytes32) returns grants[id] verbatim (contracts/src/ClausSignalStore.sol:125), and a grant that has not been registered is the zero struct: publisher address(0), revoked false. The guard therefore throws before chain.registerGrant is reached for exactly the documented case (docs/signals.md step 3, docs/pulse-walkthrough.md:156: signal_grant_prepare -> owner signs -> signal_grant_register -> publisher sends).

  The only ids that pass are grants already registered and finalized (a no-op repeat) or already revoked onchain (then rejected as signal_grant_inactive). Through the HTTP layer the code maps to 404 (interfaces/http.mjs).

  Net effect: no new publisher grant can be registered through the hosted API on Mainnet or Sepolia since this commit, which blocks every record publication by a new publisher (prepareRecord requires an active grant). This is a liveness regression introduced by this delta, not a permission bypass; writes still fail closed.

  The unit test added in this commit masks it because the fixture mock chain.grant() unconditionally returns {revoked:false}, and the Anvil lifecycle test calls signalChain.registerGrant directly, never signals.grantRegister.

  Minimal fix preserving the intended check: treat signal_grant_not_found as "not registered, not revoked", e.g. const g=await chain.grant(s,row.value.grantId).catch(e=>{if(e.code!=='signal_grant_not_found')throw e;return {revoked:false};}); requireThat(!g.revoked,'signal_grant_inactive'); (a pre-revoked slot still returns revoked:true from the adapter because the contract keeps revoked=true with a zero publisher), or expose a raw grant-state read in the adapter for this pre-check.

  Merged from four specialist reports (economics, permissions, flow, math) of the same defect.

  whole finding

  State: real Anvil (chain id 1) with real ClausApprovalExecutor, ClausPulseModule, ClausSignalFactory and ClausSignalStore from forge build; real adapters/signal-read.mjs behind the real createSignalRouter; real src/signals/index.mjs; only artifact-evidence validation stubbed. Steps: signal_store_prepare -> owner sends -> anvil_mine 96 -> signal_submit => confirmed; signal_grant_prepare {publisher, maximumWrites:3, minimumInterval:1, expiresAt: head+86400, nonce:"14"} => awaiting_signature; owner signs grant.typedData; onchain grant(grantId) is {publisher:0x0, revoked:false}. Input: grantRegister("owner","p",{operationId:grant.id, signature}). Expected (docs/signals.md step 3): state "prepared" with the publisher's registerGrant transaction intent. Actual: rejects with code signal_grant_not_found thrown from adapters/signal-read.mjs:72 via src/signals/index.mjs:195; the operation stays awaiting_signature. Control in the same test: signalChain.registerGrant(signalRow,binding,grant,signature) resolves with transaction.from === publisher and sending it registers the grant onchain, proving line 195 is the sole blocker.

  whole reproduction

• 2.mediumBoth documented ends of the grant expiresAt range are rejected by the new chain-clock bound, and signal_grant_expiry has no HTTP mapping so the client gets a retryable 503 service_unavailableadapters/signal-read.mjs:135

        requireThat(terms.expiresAt>Number(head.timestamp)+60&&terms.expiresAt<=Number(head.timestamp)+30*86400,'signal_grant_expiry');

  grantPrepare (src/signals/index.mjs:182) validates expiresAt against the SERVER clock with an inclusive range [floor(now/1000)+60, floor(now/1000)+30*86400], which is what docs/signals.md ("30 days") and the signal_grant_prepare openapi description advertise. The adapter added in this commit re-checks the same value against the LATEST block timestamp with a different comparator: exclusive > head+60 and <= head+30d.

  (a) Between blocks head.timestamp normally lags the server clock by 0-12 s, so the documented maximum now+30d exceeds head+30d and is rejected. (b) Whenever head.timestamp >= the server second (a block mined this second, or a few seconds of skew, both routine) the documented minimum now+60 fails > head+60.

  The rejection code signal_grant_expiry is new in this commit and absent from the errors map in interfaces/http.mjs:2-39; errorStatus() falls back to 503 because the code does not match the 400 regex, and errorBody() replaces it with {error:"service_unavailable",category:"availability",retryable:true}.

  A client following the documented range thus receives a deterministic validation failure labelled as a transient outage and will retry forever; operators see false dependency outages, the very thing this commit's discovery change set out to isolate.

  Fix: map signal_grant_expiry to 400/409 in interfaces/http.mjs, and make the two bounds consistent (validate grantPrepare against the same head timestamp the adapter uses, or document/derive the API range as (head+60, head+30d]).

  whole finding

  Same Anvil fixture as the first finding, API wired to the real adapter, with the API server clock set relative to the chain head. Case 1: server clock = head+3 s (head lags, the normal case); signal_grant_prepare {publisher, maximumWrites:3, minimumInterval:1, expiresAt: floor(serverNow/1000)+30*86400, nonce:"21"}; this passes the API range check at src/signals/index.mjs:182. Expected: awaiting_signature operation. Actual: rejects with code signal_grant_expiry; errorStatus(error)===503 and errorBody(error) deep-equals {error:"service_unavailable",category:"availability",retryable:true}. Concrete numbers: head=H, serverNow=H+3, expiresAt=H+3+2592000 > adapter bound H+2592000. Case 2: server clock = head (block mined this second); expiresAt: floor(serverNow/1000)+60 (documented minimum). Expected: accepted. Actual: signal_grant_expiry (H+60 is not > H+60).

• 3.lowScheduler finishes a run as failed and releases the lane once the engine row is confirmed/reverted even though the hash was never attached to the API operation (signal_submit kept failing)reference/pulse-scheduler.mjs:49

     const unresolved=signed&&!['confirmed','reverted','cancelled'].includes(signed.value.state);

  Before 7b62bd0 any chain-transactions row for the run's operation kept the run non-terminal (terminal=!signed&&(...)), so a hosted write whose signal_submit call to the network API failed kept retrying at 60 s until the hash was journaled. The new rule treats confirmed/reverted/cancelled engine rows as resolved and makes the run terminal on run.expiresAt<=now() or a listed code.

  But the engine hash reaches the API operation only through call("signal_submit") in reference/pulse-pipeline.mjs:45, which runs after publisher.step and throws an uncoded error on transport/5xx failure.

  The engine reports confirmed only after finality (~13 min on mainnet) while run.expiresAt can be as little as seconds away when the write is prepared (the pipeline checks run.expiresAt>now() just before signal_record_prepare), so a late write is routinely confirmed after run.expiresAt.

  If every signal_submit attempt from broadcast through that point failed (API origin or its RPC unavailable), one more failure after run.expiresAt makes terminal=true: the job finishes "failed" with error "reference_unavailable" and no transactionHash, the lane advances, and nothing ever retries signal_submit for that run.

  The signal-operations row stays "prepared" without a hash until it expires, no signal.record_confirmed event is emitted, and worker-health reports a failed run for a write that executed onchain; a reverted row is likewise reported as reference_unavailable instead of signal_transaction_reverted. Sequence continuity is unaffected because later runs read signal_latest from chain, and the hash remains in chain-transactions for manual recovery, hence low.

  Fix: count a confirmed/reverted engine row as resolved only once the API operation carries its hash (read signal-operations for run.write.operation.id and require transactionHash===signed.value.hash, or have the pipeline persist run.transactionHash from the engine before calling signal_submit and keep retrying while it is unattached).

• 4.lowdiscovery reports permanent admission faults (signal_factory_changed, wrong_chain, signal_evidence_invalid, missing artifact, no chain client) as the transient signal_dependency_unavailablesrc/signals/index.mjs:165

          return {chainId,profile:'claus-signal-v1',admission:'unavailable',reason:'signal_dependency_unavailable'};

  The catch-all added in 7b62bd0 special-cases three not_enabled codes and maps every other error to admission "unavailable" with a fixed reason. admission() can also fail with deterministic, operator-actionable, non-sensitive codes that no retry resolves: signal_factory_changed (adapters/signal-read.mjs:42-44: chainId mismatch, factory code hash changed, factory.executor() != config.executor), wrong_chain (:35), signal_evidence_invalid (adapters/signal-evidence.mjs: reviewed factory artifact does not reproduce the deployed code), artifact not_found/corrupt from artifacts.get, and signal_chain_unavailable (router has no client for the chain).

  All now look identical to an RPC blip in the public capabilities payload (src/access/index.mjs signalProfiles) and to worker-health consumers, so a misconfigured or tampered profile is advertised as "come back later" instead of being surfaced; the comment's claim that only "a chain dependency outage closes this profile" is not what the code does. Writes still fail closed with the precise code on the write paths, so this is a diagnostic gap, not a bypass.

  Fix: keep the generic reason for errors without a code (transport/RPC) and for signal_chain_unavailable/wrong_chain, and pass through the project's own coded admission failures (e.g. admission:"not_enabled", reason:error.code), which carry no RPC detail.

• 5.lowgrantRegister applies no inclusion margin and never consults chain time, so it prepares a registration intent for a grant that is seconds from (or already past) expiry and is guaranteed to revertsrc/signals/index.mjs:192

        requireThat(row.value.expiresAt > now() && row.value.input.expiresAt * 1000 > now(), 'signal_operation_expired');

  This commit adds a 60 s chain-clock margin at signal_grant_prepare (adapters/signal-read.mjs:135) and at record preparation (:158), and the delta description says it "requires 60s inclusion margin on grant/record validity".

  The step that actually emits the transaction the publisher broadcasts, grantRegister -> chain.registerGrant (adapters/signal-read.mjs:143-150), checks only owner, authorityGeneration and the signature; the API-side guard on this line compares the grant expiresAt against the server clock with zero margin.

  The grant operation row lives 24 h (src/signals/index.mjs:103) while a grant may have been prepared with 61 s of life, so an intent can be handed out with one second left, or already expired on chain whenever the server clock is behind block time.

  ClausSignalStore.registerGrant reverts with InvalidGrant when g.expiresAt <= block.timestamp (contracts/src/ClausSignalStore.sol:107-110), so the intent can only burn the publisher's gas and then surfaces as signal_transaction_reverted.

  Fix: in grantRegister (or registerGrant) read the latest block and require terms.expiresAt > head.timestamp+60, returning signal_grant_expiry, mirroring the prepare-time check. (On this tree the API path is reached only after the first finding is fixed, because line 195 throws first; the chain-time part is shown through the adapter call grantRegister delegates to.)

  whole finding

  API path (mock chain, unit fixture rows, chain.grant returning {revoked:false}): grantPrepare with expiresAt = floor(now/1000)+3600, then set now() = expiresAt*1000-1000 (one second of life left) and call grantRegister("owner","p",{operationId, signature}).

  Expected: rejection with signal_grant_expiry (margin) like prepare.

  Actual: returns state "prepared" with the registration transaction.

  Chain path (Anvil, case 3 of test/scratch/grant-register-anvil.test.mjs): terms.expiresAt = head+61; signalChain.prepareGrant succeeds; mine 70 blocks at 1 s so head >= expiresAt; signalChain.registerGrant(signal,binding,grant,ownerSignature) resolves with transaction.from === publisher instead of rejecting; sending that transaction from the publisher with gas 300000 yields a receipt with status "reverted".

   Review complete. The findings file holds one substantiated defect.

   Finding (high, liveness regression in this commit): the new onchain-revocation guard in grantRegister at src/signals/index.mjs:195 breaks every first-time grant registration on a real chain. It reads the grant through chain.grant, and the production adapter throws signal_grant_not_found whenever the onchain publisher is zero and the grant is not revoked. That is exactly what the store returns for an id that has not been registered yet, which is the only case signal_grant_register exists for. Only already-registered or pre-revoked ids get past the guard. The unit fixture hides it because its mock returns {revoked:false} unconditionally, and the Anvil lifecycle calls the adapter's registerGrant directly instead of the API. Reproduced with a scratch node test that drives createSignals with the real createSignalRead over a stub RPC returning the zero struct:

   Error: signal_grant_not_found
     at grant (adapters/signal-read.mjs:72)
     at async Object.grantRegister (src/signals/index.mjs:195:21)
   

   The minimal fix is to treat signal_grant_not_found as "not revoked" at that line while keeping the signal_grant_inactive rejection for revoked ids.

   Checked and not defective in the changed scope:

   • Replacement evidence match in reconcile lines up with the real engine's cancelled row: same key, preserved original hash, lowercase sender/to/data, chainId and value '0'. The engine only writes replacement from finalized history, and users cannot write chain-transactions.
   • Scheduler now releases the lane on confirmed, reverted and cancelled rows, matching when the engine frees the wallet slot. Unknown and prepared rows still hold it.
   • Pipeline reads the finalized grant once, clamps service expiry, and the terminal pulse_result_expiring only fires where nothing has been broadcast.
   • Discovery swallowing RPC errors no longer breaks the whole capabilities endpoint when the Mainnet client is absent, and leaks no RPC detail.
   • The 60 second grant and record margins are consistent with the contract's expiresAt and validUntil checks.

   The four existing changed test files pass on this commit. Dependencies were installed into the ignored node_modules only, and the reproduction lives under test/scratch/, which is not kept.

   • highgrantRegister's new onchain revocation check rejects every first-time grant registration with signal_grant_not_foundsrc/signals/index.mjs:195

     This commit adds a pre-registration guard in grantRegister that reads the grant through chain.grant(). With the production adapter (adapters/signal-read.mjs:69-74, exported at :89-94) that call does requireThat(value?.terms && (!zero(value.terms.publisher) || value.revoked), 'signal_grant_not_found').

     ClausSignalStore.grant(bytes32) (contracts/src/ClausSignalStore.sol:125) returns grants[id], which for any id that has not yet been registered is the zero struct: publisher 0x0, revoked false. A grant being registered through signal_grant_register is by definition not yet registered, so the adapter throws signal_grant_not_found before registerGrant is reached.

     The only ids that pass the guard are grants that are already registered (idempotent repeat) or that the owner already revoked onchain (which then correctly fails with signal_grant_inactive). The intended case, a fresh signed grant, can never be prepared. The unit fixture masks this because its mock chain.grant unconditionally returns {revoked:false}, and the Anvil lifecycle test calls the adapter's registerGrant directly, bypassing src/signals/index.mjs.

     Documented step 3 of docs/signals.md and line 156 of docs/pulse-walkthrough.md fail on Mainnet and Sepolia, so no new publisher can be onboarded through the API and the whole signal lifecycle after store creation is blocked.

     Minimal fix: treat signal_grant_not_found as not revoked here (catch that code, or read the raw GrantState and check only .revoked), keeping the signal_grant_inactive rejection for revoked ids.

     whole finding

     State: store registered for project p on chain 1; signal_grant_prepare succeeded (operation in awaiting_signature).

     Input: signal_grant_register {projectId:'p', operationId:, signature:<any 65-byte hex>} while chain.grant is the real createSignalRead adapter and the RPC returns the zero GrantState for the grant id (what ClausSignalStore returns for an unregistered id).

     Expected: operation moves to state 'prepared' with the registerGrant transaction (docs/signals.md step 3).

     Actual: the call rejects with code signal_grant_not_found thrown from adapters/signal-read.mjs:72 via src/signals/index.mjs:195, and the operation stays awaiting_signature forever.

     Reproduced with test/scratch/grant-register-not-found.test.mjs (node --test): Error: signal_grant_not_found at grant (adapters/signal-read.mjs:72) ... at async Object.grantRegister (src/signals/index.mjs:195:21).

3. Audit permissionsAgent #939found 1 high, 1 low, 1 info

   Review complete. Findings are written to .imd-findings.json, with reproductions under test/scratch/.

   Scope reviewed: the runtime delta between 8b03d35 and HEAD only: src/signals/index.mjs (discovery isolation, grant registration revocation checks, replacement evidence in reconcile), adapters/signal-read.mjs (chain-time grant ceiling and 60s inclusion margins), reference/pulse-pipeline.mjs (finalized grant read and expiry clamp), reference/pulse-scheduler.mjs (unresolved-row retention), plus the engine code those paths depend on. The existing targeted suites pass locally. Solidity, permissions and intake were not re-audited.

   Findings

   • High. Grant registration through the API is broken for every fresh grant. The new onchain pre-check in grantRegister calls the real adapter's grant read, which throws signal_grant_not_found for any grant id whose store entry is the zero struct. An unregistered, unrevoked grant is exactly that struct, so the walkthrough's signal_grant_register step fails before the intent is built. The unit fixture masks it with a mock that always returns revoked:false, and the Anvil test bypasses the API method. test/scratch/grant-register-fresh.test.mjs fails on this tree with that code.
   • Low. A confirmed hosted write can be dropped as a failed run. The scheduler now treats a confirmed engine row as resolved, but the hash only reaches the API operation through signal_submit on the same step. If that call keeps failing past run expiry, the job finishes as failed, the lane is released, and the operation stays prepared with no hash and no confirmation event. The pre-delta code retained the lane here. test/scratch/scheduler-confirmed-orphan.test.mjs shows failed where unavailable was expected.
   • Info. Discovery collapses permanent admission faults into a transient reason. A factory code mismatch, invalid evidence, missing artifact or absent mainnet client all surface as signal_dependency_unavailable. Writes still fail closed, so this is observability only.

   Checked and found sound: replacement evidence is only accepted from the internal engine row and requires exact hash, chain, sender, target, calldata and zero value; signal_submit cannot inject it. Revoked grants are rejected at both API and chain level before a registration intent exists. The 60-second margins and the 30-day ceiling are checked against the latest block, and the pipeline clamps publication and record validity to the finalized grant. Unknown and prepared engine rows still hold the lane across expiry and restart.

   • highgrantRegister now reads the grant through the real adapter before registration, so every fresh grant fails with signal_grant_not_foundsrc/signals/index.mjs:195

     Commit 7b62bd0 added an onchain revocation pre-check to grantRegister that calls chain.grant() for the grant being registered. In production chain is createSignalRouter -> createSignalRead, whose grant() helper (adapters/signal-read.mjs:72) throws 'signal_grant_not_found' whenever the store returns a GrantState with a zero publisher and revoked == false.

     ClausSignalStore.grant(id) returns grants[id] verbatim, and a grant that has not been registered yet is exactly that zero struct (contracts/src/ClausSignalStore.sol:125). The pre-check therefore rejects the normal case: a signed, unrevoked, not-yet-registered grant. The only grants that pass are ones already registered (where registerGrant is a no-op repeat) or ones pre-revoked onchain (which then fail the .revoked check).

     The unit fixture in test/signals.test.mjs masks this because its mock chain.grant always returns {revoked:false}; the Anvil lifecycle test calls signalChain.registerGrant directly and never goes through signals.grantRegister.

     Net effect: the hosted API flow signal_grant_prepare -> signal_grant_register (docs/pulse-walkthrough.md step 4, docs/signals.md step 3) is broken for every new grant on Sepolia and Mainnet since this commit; no publisher grant can be registered through the API, so no record can be published by the hosted path. This is a liveness regression introduced by this delta, not a permission bypass.

     whole finding

     State: a verified project signal store on chain; owner has called signal_grant_prepare and signed the typed grant; the grant id is not registered and not revoked onchain (ClausSignalStore.grant(id) returns {terms:{publisher:0x0,...},used:0,lastWrite:0,revoked:false}).

     Input: POST /v1/projects/{projectId}/signal/grants/register {operationId, signature}.

     Expected: operation returned with state 'prepared' and the registerGrant transaction intent for the publisher to sign.

     Actual: 404 'signal_grant_not_found' thrown from adapters/signal-read.mjs:72 via src/signals/index.mjs:195 before chain.registerGrant is reached; the operation stays 'awaiting_signature' until it expires.

     Reproduced by test/scratch/grant-register-fresh.test.mjs (createSignals wired to createSignalRead({client: mock node returning the zero GrantState}).grant): fails on this tree with code 'signal_grant_not_found'.

     Fix: treat 'signal_grant_not_found' from chain.grant as 'not registered, not revoked' in grantRegister (catch that code and continue), or expose a raw grant-state read in the adapter for this pre-check; keep rejecting only when revoked === true.

     whole reproduction

   • lowScheduler releases a confirmed hosted write as a failed run when signal_submit keeps failing past run expiry, leaving the API operation without its hashreference/pulse-scheduler.mjs:49

     Before this commit any signed engine row kept the lane (terminal=!signed&&...). Now only rows outside confirmed/reverted/cancelled do. The engine row reaching 'confirmed' or 'reverted' does not mean the API operation has been reconciled: the pipeline attaches the engine hash to the API operation only through call('signal_submit') on the same step (reference/pulse-pipeline.mjs:45), and a failed signal_submit throws out of step() into this catch.

     With the row already 'confirmed' and the thrown error carrying no code (network failure -> 'reference_unavailable'), unresolved is false, so once run.expiresAt (at most one interval, 1h) has passed the job is finished as 'failed' with no transactionHash, the next slot is scheduled, and nothing ever retries signal_submit for that run.

     The signal-operations row for that record stays 'prepared' with no transactionHash until it expires, no signal.record_confirmed event is emitted, signal_operation never shows the confirmed receipt, and worker-health reports a failed run for a write that actually landed. The same applies to a 'reverted' row: the run is marked failed with error 'reference_unavailable' instead of 'signal_transaction_reverted' and the API operation never learns the hash.

     Recovery requires an operator to find the hash in chain-transactions and call signal_submit by hand. Sequence continuity for later runs is unaffected because the pipeline reads signal_latest from chain.

     whole finding

     State: reference-pulse scheduler run R with run.write.operation.id = X; chain-transactions row 'signal-record:X' in state 'confirmed' (engine broadcast and finalized); the API origin is unreachable so client.call('signal_submit') rejects with a plain Error (no code).

     Steps: tick() once -> 'unavailable' (retry); advance now() past R.expiresAt (intervalMs later); tick() again.

     Expected (and pre-7b62bd0 behaviour): the lane is still held and the hash keeps being retried against the API ('unavailable'), since the confirmed hash has not been attached to the API operation.

     Actual: jobs.finish(state:'failed', result.run without transactionHash), tick returns {state:'failed', error:'reference_unavailable'}, a new slot is scheduled, and signal-operations X remains 'prepared' with no transactionHash.

     Reproduced by test/scratch/scheduler-confirmed-orphan.test.mjs, which fails on this tree with actual 'failed' vs expected 'unavailable'.

     Fix: treat a confirmed/reverted engine row as resolved only once the API operation carries that hash (e.g. also read signal-operations X and require transactionHash === signed.value.hash before allowing terminal), or have the pipeline persist run.transactionHash from the engine before calling signal_submit and let the scheduler keep retrying while run.transactionHash is unattached.

     whole reproduction

   • infodiscovery reports permanent admission faults (factory code mismatch, missing artifact, evidence invalid) as a transient 'signal_dependency_unavailable'src/signals/index.mjs:165

     The new catch-all only special-cases three codes and maps every other error to admission 'unavailable' with a fixed reason. admission() can also fail with deterministic, operator-actionable codes that are not RPC outages: 'signal_factory_changed' (deployed factory bytecode or executor no longer matches network-capabilities signal:), 'signal_evidence_invalid' (factory artifact does not reproduce the deployed code), 'artifact_not_found' (factory artifact missing from artifact-store), 'wrong_chain', and 'signal_chain_unavailable' (no mainnet client configured).

     All of these now look identical to a flaky RPC in the public capabilities payload and worker-health consumers, so a misconfigured or tampered profile is advertised as 'come back later' rather than being surfaced to the operator. Writes still fail closed (admission() is rethrown on the write paths), so this is an observability gap, not a bypass.

     The intent of not leaking RPC error text is sound; the fix is to keep the generic reason for unknown/transport errors but pass through the project's own coded, non-sensitive admission failures (or at least distinguish 'misconfigured' from 'unavailable').

     whole finding

     State: network-capabilities signal:1 enabled, reviewed and assessed, but factoryCodeHash differs from keccak256 of the code at config.factory (real adapter validateAdmission throws requireThat(...,'signal_factory_changed')).

     Input: GET capabilities (access.discovery -> signals.discovery(1)).

     Expected: a distinguishable, non-transient admission state/reason such as 'signal_factory_changed'.

     Actual: {chainId:1, profile:'claus-signal-v1', admission:'unavailable', reason:'signal_dependency_unavailable'}.

     Shown by test/scratch/discovery-misconfig.test.mjs, which passes on this tree by asserting the current (collapsed) output.

4. Audit flowAgent #1614found 1 high, 1 medium, 1 low

   The Anvil node is stopped (the only match is the shell's own command line), no tracked file changed, and the findings file validates with all three snippets matching the tree.

   Review of 7b62bd0 against 8b03d35 is complete. Three substantiated defects are in .imd-findings.json, ranked by severity.

   • High, grant registration is unreachable through the API. The new onchain-revocation guard in grantRegister calls the adapter's grant reader before registration. The contract's grant(id) getter returns a zeroed struct for an unregistered id, and the adapter turns that into signal_grant_not_found. So every first registration of a freshly owner-signed grant is rejected, which blocks the documented lifecycle and every later record. Reproduced on real Anvil with the real contracts and adapter: the adapter's own registerGrant accepts the signature, the API method throws. The unit test misses it because its mock reader always returns an unrevoked grant.
   • Medium, scheduler finalizes a confirmed write as a failed run. Confirmed and reverted engine rows now count as resolved. If the pipeline's hash hand-off to the API fails once past the one-hour run deadline, which is routine since the engine only confirms after finality, the run is marked failed, the lane advances, and the operation never receives its transaction hash. Reproduced with the scheduler and an in-memory store.
   • Low, discovery mislabels permanent admission failures. The catch-all maps coded, non-transient errors such as a changed factory code hash, wrong chain id, invalid artifact evidence or a missing artifact to a "dependency unavailable" outage. Writes still fail closed with the precise code, so the impact is diagnostic.

   Checked and found sound: the replacement-evidence match in reconcile lines up field by field with what the transaction engine actually writes, cancelled rows without broadcast can never carry an attached hash, the HTTP layer maps uncoded RPC errors to a generic 503 so no RPC detail leaks over the wire, and the grant and record expiry margins are consistent between the adapter, the pipeline clamp and the contract ceiling. Existing targeted suites pass as a baseline. Scratch tests live under test/scratch/ and are not part of the submission.

   • highgrantRegister can never prepare a first grant registration: the new onchain-revocation guard reads grant(id) of a not-yet-registered grant and the adapter throws signal_grant_not_foundsrc/signals/index.mjs:195

     This line was added in 7b62bd0 (absent at 8b03d35). It calls chain.grant() before chain.registerGrant(). adapters/signal-read.mjs grant() (line 69-74) does requireThat(value?.terms && (!zero(value.terms.publisher) || value.revoked), 'signal_grant_not_found'), and ClausSignalStore.grant(bytes32) (contracts/src/ClausSignalStore.sol:125) returns the zeroed GrantState for any id that has not been registered yet (publisher == address(0), revoked == false).

     So for the normal case, a freshly owner-signed grant that has never been registered onchain, the guard throws signal_grant_not_found and grantRegister never reaches registerGrant. The only grants that pass the guard are ones already registered (where re-registration is a no-op per the contract) or pre-revoked ones (which are then rejected as inactive).

     The documented lifecycle (docs/signals.md step 3 'Call signal_grant_register ...', docs/pulse-walkthrough.md:156 call('signal_grant_register',{operationId:grant.id,signature:grantSignature})) is therefore unreachable through the API at this commit: no new publisher grant can be registered via the service, which blocks every new record (prepareRecord requires an active grant).

     The unit test in test/signals.test.mjs does not catch this because its mock chain.grant() always returns {revoked:false}; test/signal-integration.test.mjs calls the adapter's registerGrant directly and never exercises the API method.

     Minimal fix: treat signal_grant_not_found as 'not registered, not revoked', e.g. const g=await chain.grant(s,row.value.grantId).catch(e=>{if(e.code!=='signal_grant_not_found')throw e;return {revoked:false};}); requireThat(!g.revoked,'signal_grant_inactive'); (the pre-revoked case still returns revoked:true from the adapter because the contract keeps revoked=true with a zero publisher).

   • mediumScheduler finalizes a run as failed and releases the lane when the engine row is confirmed/reverted but the hash was never accepted by the API (signal_submit failed), leaving the operation permanentlyreference/pulse-scheduler.mjs:49

     Before 7b62bd0 any chain-transactions row for the run's operation kept the run non-terminal (terminal=!signed&&(...)), so a confirmed hosted write whose signal_submit call to the network API failed kept retrying at 60s until the hash was journaled. The new rule treats confirmed/reverted engine rows as 'resolved' and makes the run terminal on run.expiresAt<=now() or any listed code.

     But the pipeline attaches the engine hash to the API operation only via call('signal_submit',...) in reference/pulse-pipeline.mjs:45, which runs after publisher.step and can throw an uncoded transport/5xx error. The engine (finalized:true) reports confirmed only after finality (~13 min on mainnet), while run.expiresAt is now+intervalMs (1h) from slot start, so a write broadcast late in the slot is routinely confirmed after run.expiresAt.

     Then a single failed signal_submit (or signal_operation) call makes terminal=true: the job is finished 'failed' with error 'reference_unavailable', the lane advances to the next slot, and the signal-operations row stays 'prepared' with no transactionHash forever, although the publish executed onchain.

     This contradicts docs/signals.md ('Any earlier uncertain transaction keeps its original hash and remains independently reconcilable' - here the API never learns the hash) and misreports a successful write as a failed run in worker-health. The same applies to 'reverted' rows (publisher.step returns the hash with error signal_transaction_reverted and the pipeline still calls signal_submit first).

     Minimal fix: only count a confirmed/reverted engine row as resolved once the API operation carries its hash, e.g. read 'signal-operations' for run.write.operation.id and require op.transactionHash===signed.value.hash (or op.state in confirmed/failed) before treating the row as resolved; cancelled rows (no broadcast / replacement proven) may stay as they are.

     The catch-all added in 7b62bd0 is meant to isolate RPC outages without exposing RPC details, but it also swallows the adapter's definitive, coded admission failures: adapters/signal-read.mjs factory() throws 'signal_factory_changed' (config.chainId mismatch, factory code hash changed, factory.executor() != config.executor) and 'wrong_chain' (RPC serves a different chain id); adapters/signal-evidence.mjs throws 'signal_evidence_invalid' when the reviewed factory artifact does not reproduce the onchain bytecode; artifact-store throws 'not_found'/'artifact_corrupt'.

     None of these resolve by retrying, yet the public capabilities endpoint (src/access/index.mjs:93 signalProfiles) now labels the profile 'unavailable' with a reason that says 'dependency unavailable', so operators and clients cannot distinguish a misconfigured or tampered admission from an RPC blip, and the comment's own claim that only 'a chain dependency outage closes this profile' is not what the code does.

     Writes still fail closed with the precise code, so impact is diagnostic, not a bypass.

     Fix: whitelist the transient classes instead of blacklisting the three not_enabled codes, e.g. return 'unavailable' only for errors without a code (transport/RPC) or for 'signal_chain_unavailable'/'wrong_chain', and map the coded permanent failures to admission:'not_enabled' with reason:error.code (they already carry no RPC detail).

     whole finding

     State: the rows from test/signals.test.mjs fixture (network-capabilities signal:1 enabled, reviewed case, accepted assessment) and chain.validateAdmission that throws a coded error, e.g. requireThat(false,'signal_factory_changed') (what the real adapter throws when config.factoryCodeHash no longer matches the chain).

     Call signals.discovery(1).

     Expected: a definitive state such as {admission:'not_enabled', reason:'signal_factory_changed'} (or the error surfacing), since retrying cannot change it.

     Actual: {chainId:1, profile:'claus-signal-v1', admission:'unavailable', reason:'signal_dependency_unavailable'}.

     Verified for codes signal_factory_changed, wrong_chain, signal_evidence_invalid and an artifacts.get that throws 'artifact_not_found': all four return the identical outage payload (scratch test with createSignals({chain:{validateAdmission:async()=>requireThat(false,code)}, artifacts:{get:...}}) passed for each).

5. Audit mathAgent #1850found 1 high, 1 medium, 1 low

   The review is complete. The findings file holds three substantiated defects, all in the changed runtime delta, each reproduced on a real Anvil chain through the real createSignalRead adapter. No tracked file was modified.

   Findings written to .imd-findings.json

   • High, src/signals/index.mjs:195. The new on-chain revocation guard in grantRegister calls the adapter's grant() for a grant that has not been registered yet. That helper treats a zero publisher with revoked=false as "not found" and throws. In the documented prepare, sign, register flow the grant is always unregistered at this point, so every first-time registration fails with a 404. The unit test mocks chain.grant to always succeed and the lifecycle test bypasses the API, which is why 466 passing tests did not catch it. Reproduction: test/scratch/grant-register-anvil.test.mjs.

   • Medium, adapters/signal-read.mjs:135. The API validates expiresAt against the server clock inclusively, then the adapter re-validates it against the latest block timestamp exclusively. With the head lagging the server by a few seconds the documented maximum of 30 days is rejected, and with the head at or ahead of the server second the documented minimum of 60 seconds is rejected. The new signal_grant_expiry code is missing from the HTTP error map, so the client receives a retryable 503 service_unavailable, turning a deterministic validation rejection into an apparent outage. Reproduction: cases 1 and 2 of test/scratch/grant-expiry-boundaries.test.mjs.

   • Low, src/signals/index.mjs:192. The 60-second chain-clock margin exists only at prepare. Registration checks the server clock with no margin, so a grant already expired on chain is still handed out as a prepared intent that reverts with InvalidGrant and costs the publisher gas. Reproduction: case 3 of the same scratch test.

   What was checked and found sound. The scale handling in the pipeline's grant clamp, the ms and seconds Math.min operations, the 900s and 1000ms freshness margins, the record validity bounds against the contract's publish checks, the scheduler's unresolved-state set against the engine's actual states, and the replacement-evidence matching in reconcile all hold under the inputs I traced. The RPC-outage, mismatched replacement, revoked registration, restart and unknown-broadcast cases in the repo's own tests pass.

   Limits. Scratch tests stub only artifact validation, since the admission path needs the project's own compiler output. The Anvil lifecycle test in the repo stayed skipped because its environment variables are not provided here. Solidity was not re-audited per the task scope.

   • highgrantRegister reads the on-chain grant before it exists, so every first-time grant registration is rejected with signal_grant_not_foundsrc/signals/index.mjs:195

     The new on-chain revocation guard in grantRegister calls chain.grant() for the grant that is about to be registered. The real adapter (adapters/signal-read.mjs:69-74) implements grant() as requireThat(value?.terms && (!zero(value.terms.publisher) || value.revoked), 'signal_grant_not_found'): the zero-publisher sentinel means 'not found' unless the slot is already revoked.

     In the documented flow (docs/signals.md steps 2-3, docs/pulse-walkthrough.md:149-156) signal_grant_register is called after signal_grant_prepare and BEFORE the publisher sends the registration transaction, so grants[id].terms.publisher is still address(0) and revoked is false. chain.grant() therefore throws signal_grant_not_found (HTTP 404 per interfaces/http.mjs:28) on every genuine registration; the only grants that pass the guard are ones already registered on chain (a no-op) or already revoked (then rejected by the guard).

     The unit test in test/signals.test.mjs mocks chain.grant to always return a found grant, and the Anvil lifecycle test calls the adapter's registerGrant directly, so neither exercises this path.

     Boundary: the zero-address sentinel has two meanings in the read path ('absent' in grant()/latest() versus 'not yet registered' in grantRegister).

     Fix: resolve on-chain state without throwing on absence, e.g. read the raw grant in grantRegister and treat {publisher:0, revoked:false} as unregistered (allowed) and revoked===true as inactive, or add an adapter method such as grantRevoked(signal,id) that returns the revoked flag for an empty slot.

     whole finding

     Real adapter on Anvil (chain id 1), script test/scratch/grant-register-anvil.test.mjs: deploy ClausApprovalExecutor + ClausPulseModule, register a project, deploy ClausSignalFactory, create the store through signalChain.prepareStore/observe, then: (1) terms={publisher,maximumWrites:3,minimumInterval:1,expiresAt:head+86400,nonce:'14'}; grant=await signalChain.prepareGrant(signal,binding,terms); await signalChain.grant(signal,grant.grantId) rejects with code signal_grant_not_found, while signalChain.registerGrant(signal,binding,grant,ownerSignature) resolves with the registration transaction (adapter alone is fine).

     (2) Wire createSignals with chain={...createSignalRouter({mainnet:signalChain}),validateAdmission:async()=>{},validateStoreBuild:async()=>{}} and the same store rows the unit fixture uses; op=await api.grantPrepare('owner','p',{...terms,nonce:'15',idempotencyKey:'grant-15'}) -> state awaiting_signature; sig=await owner.signTypedData(op.typedData); api.grantRegister('owner','p',{operationId:op.id,signature:sig}).

     Expected: {state:'prepared', transaction:{from:publisher,...}}.

   • mediumBoth ends of the documented grant expiresAt range are rejected by the chain-clock bound, and the new signal_grant_expiry code has no HTTP mapping so clients receive a retryable 503 service_unavailableadapters/signal-read.mjs:135

     grantPrepare (src/signals/index.mjs:182) admits expiresAt in the inclusive server-clock range [floor(now/1000)+60, floor(now/1000)+30*86400], which is what docs/signals.md:31 ("30 days") and the openapi description advertise. The adapter then re-checks the same value against the LATEST block timestamp with a different comparator and clock: exclusive > head+60 and <= head+30d. Two boundary × invariant seams follow.

     (a) On any live chain head.timestamp is normally behind the server clock by 0-12s (nothing was mined this second), so the documented maximum now+30d fails <= head+30d by the lag. (b) Whenever head.timestamp >= the server second (a block mined this second, or a few seconds of clock skew, both routine on mainnet) the documented minimum now+60 fails > head+60.

     The rejection code signal_grant_expiry is thrown through the HTTP layer but is absent from the errors map in interfaces/http.mjs:2-39; errorStatus() falls back to 503 because the code does not match the /^(invalid_|...)/ 400 regex, and errorBody() then replaces the code with 'service_unavailable', category 'availability', retryable:true.

     A client that follows the documented range therefore sees a deterministic validation failure as a transient outage and retries it forever; operators monitoring 503s see a false dependency outage, which is exactly what this commit's discovery change set out to isolate.

     Fix: map signal_grant_expiry to 400 (or 409) in interfaces/http.mjs, and make the two bounds consistent, e.g. have grantPrepare validate against the same head timestamp the adapter uses, or derive the API range as [head+61, head+30d] and document it, or relax the adapter upper bound to head+30d+(now_s-head) so the contract's registration-time check expiresAt <= block.timestamp + 30 days remains the binding limit.

     whole finding

     Real adapter on Anvil, script test/scratch/grant-expiry-boundaries.test.mjs (same deployment as the first finding; createSignals wired to the real createSignalRead with only artifact validation stubbed).

     Case 1: mine the finality blocks with 0s spacing so head.timestamp ~= wall clock, wait 3s so the head lags the server by ~3s, then api.grantPrepare('owner','p',{publisher,maximumWrites:3,minimumInterval:1,expiresAt:Math.floor(Date.now()/1000)+30*86400,nonce:'21',idempotencyKey:'max'}).

     Expected: an awaiting_signature operation (value is inside the documented and API-validated range).

     Actual: rejects with code 'signal_grant_expiry'; errorStatus(error)===503 and errorBody(error) deep-equals {error:'service_unavailable',category:'availability',retryable:true}.

     Case 2: evm_setNextBlockTimestamp(floor(Date.now()/1000)+5) then mine one block, then grantPrepare with expiresAt:Math.floor(Date.now()/1000)+60 (documented minimum).

     Expected: accepted.

     Actual: 'signal_grant_expiry', status 503.

   • lowgrantRegister prepares a registration intent for a grant whose expiresAt has already passed on chain, which is guaranteed to revert with InvalidGrant and waste the publisher's gassrc/signals/index.mjs:192

     The 60s chain-clock margin added at adapters/signal-read.mjs:135 runs only at signal_grant_prepare. The step that actually emits the transaction the publisher will broadcast, grantRegister -> chain.registerGrant (adapters/signal-read.mjs:143-150), checks owner, authorityGeneration and the signature but never consults chain time; the API-side guard on this line compares the grant's expiresAt only against the server clock with no margin.

     The grant operation row lives for 24h (expiresAt: now()+86400000 at src/signals/index.mjs:103) while a grant may be prepared with as little as 61s of life, so there is an unbounded window in which a signed-but-expired grant is still turned into a 'prepared' intent.

     ClausSignalStore.registerGrant reverts with InvalidGrant when g.expiresAt <= block.timestamp (contracts/src/ClausSignalStore.sol:107-110), so the intent can only burn the publisher's gas. docs/signals.md:78 states the margin is not an inclusion guarantee; this case is not about the margin but about an already-expired grant being handed out as a valid intent.

     Fix: in registerGrant (or before calling it in grantRegister) read the latest block and require terms.expiresAt > head.timestamp + 60, returning signal_grant_expiry, mirroring the prepare-time check.

     whole finding

     Case 3 of test/scratch/grant-expiry-boundaries.test.mjs on Anvil: terms={publisher,maximumWrites:3,minimumInterval:1,expiresAt:head+61,nonce:'23'}; grant=await signalChain.prepareGrant(signal,binding,terms) succeeds (head+61 > head+60).

     Mine 70 blocks at 1s so head >= terms.expiresAt. reg=await signalChain.registerGrant(signal,binding,grant,await owner.signTypedData(grant.typedData)).

     Expected: rejection (signal_grant_expiry or signal_grant_inactive) because the grant is already expired on chain.

     Actual: resolves with reg.transaction={from:publisher,to:store,data:registerGrant(...)}.

     Sending that transaction from the publisher with gas:300000 yields a receipt with status 'reverted'.

     On the API path the same server-clock-only guard on this line passes whenever the server clock is behind chain time, but src/signals/index.mjs:195 currently throws signal_grant_not_found first (first finding), so the API path was demonstrated through the adapter call grantRegister delegates to.

6. Audit judgeAgent #1735found 1 high, 1 medium, 3 low

   The review is complete. The findings file is written at the repository root and no tracked file was changed.

   Outcome. Five findings survived reproduction, merged from the ten specialist reports. Every one was reproduced with a scratch test that runs green against this tree, meaning the defect is present. Full test sources are embedded in each finding's reproduction so they stand alone.

   • High, src/signals/index.mjs:195. The new onchain-revocation guard in grantRegister calls the adapter's grant read for a grant that has not been registered yet. The adapter throws signal_grant_not_found for a zero publisher slot, so every fresh grant registration through the API is rejected before the registration transaction is prepared. Reproduced on real Anvil with the real adapter and router; the adapter's own registerGrant succeeds in the same test, isolating the line. Four specialists reported this and I merged them into one finding.
   • Medium, adapters/signal-read.mjs:135. The API validates grant expiry against the server clock with an inclusive 60 s to 30 day range, while the adapter rechecks against the latest block with an exclusive lower bound. Both documented ends get rejected depending on head lag. The new signal_grant_expiry code has no HTTP mapping, so clients receive a retryable 503 service_unavailable for a deterministic validation failure. Reproduced on Anvil plus a direct errorStatus and errorBody check.
   • Low, reference/pulse-scheduler.mjs:49. A confirmed or reverted engine row now counts as resolved even if signal_submit never attached the hash to the API operation. After run expiry one more failed call finishes the run as failed with no hash. The permissions and flow specialists reported this at low and medium. I kept low because the hash stays in chain-transactions and sequence continuity is unaffected.
   • Low, src/signals/index.mjs:165. Discovery collapses permanent admission faults such as signal_factory_changed, wrong_chain, signal_evidence_invalid and missing artifacts into the transient signal_dependency_unavailable reason. Writes still fail closed. Merged from two reports.
   • Low, src/signals/index.mjs:192. grantRegister applies no 60 s inclusion margin and never consults chain time, so it hands out a registration intent for a grant seconds from or past expiry that reverts onchain. Shown through the API path with a mock chain and through the adapter on Anvil with a reverted receipt.

   Dropped or adjusted. Nothing was dropped outright. The specialists' own scratch files were not present in the tree, so I rewrote each reproduction and ran it myself. No Foundry proof is attached because none of the defects is in Solidity code, which the task confirms is unchanged.

   Not covered. I did not repeat the full audit or the project's test suite, as the task instructed. The Solidity contracts, permissions model and Mainnet intake were outside the delta and were not re-reviewed.

   • highgrantRegister reads the grant through chain.grant() before it exists onchain, so every first-time grant registration is rejected with signal_grant_not_foundsrc/signals/index.mjs:195

     Added in 7b62bd0 (absent at 8b03d35). The onchain-revocation guard calls chain.grant() for the grant that is about to be registered. In production chain is createSignalRouter -> createSignalRead, whose grant() helper (adapters/signal-read.mjs:69-74, public method :89-94) does requireThat(value?.terms && (!zero(value.terms.publisher) || value.revoked), 'signal_grant_not_found') at the finalized block.

     ClausSignalStore.grant(bytes32) returns grants[id] verbatim (contracts/src/ClausSignalStore.sol:125), and a grant that has not been registered is the zero struct: publisher address(0), revoked false. The guard therefore throws before chain.registerGrant is reached for exactly the documented case (docs/signals.md step 3, docs/pulse-walkthrough.md:156: signal_grant_prepare -> owner signs -> signal_grant_register -> publisher sends).

     The only ids that pass are grants already registered and finalized (a no-op repeat) or already revoked onchain (then rejected as signal_grant_inactive). Through the HTTP layer the code maps to 404 (interfaces/http.mjs).

     Net effect: no new publisher grant can be registered through the hosted API on Mainnet or Sepolia since this commit, which blocks every record publication by a new publisher (prepareRecord requires an active grant). This is a liveness regression introduced by this delta, not a permission bypass; writes still fail closed.

     The unit test added in this commit masks it because the fixture mock chain.grant() unconditionally returns {revoked:false}, and the Anvil lifecycle test calls signalChain.registerGrant directly, never signals.grantRegister.

     Minimal fix preserving the intended check: treat signal_grant_not_found as "not registered, not revoked", e.g. const g=await chain.grant(s,row.value.grantId).catch(e=>{if(e.code!=='signal_grant_not_found')throw e;return {revoked:false};}); requireThat(!g.revoked,'signal_grant_inactive'); (a pre-revoked slot still returns revoked:true from the adapter because the contract keeps revoked=true with a zero publisher), or expose a raw grant-state read in the adapter for this pre-check.

     Merged from four specialist reports (economics, permissions, flow, math) of the same defect.

   • mediumBoth documented ends of the grant expiresAt range are rejected by the new chain-clock bound, and signal_grant_expiry has no HTTP mapping so the client gets a retryable 503 service_unavailableadapters/signal-read.mjs:135

     grantPrepare (src/signals/index.mjs:182) validates expiresAt against the SERVER clock with an inclusive range [floor(now/1000)+60, floor(now/1000)+30*86400], which is what docs/signals.md ("30 days") and the signal_grant_prepare openapi description advertise. The adapter added in this commit re-checks the same value against the LATEST block timestamp with a different comparator: exclusive > head+60 and <= head+30d.

     (a) Between blocks head.timestamp normally lags the server clock by 0-12 s, so the documented maximum now+30d exceeds head+30d and is rejected. (b) Whenever head.timestamp >= the server second (a block mined this second, or a few seconds of skew, both routine) the documented minimum now+60 fails > head+60.

     The rejection code signal_grant_expiry is new in this commit and absent from the errors map in interfaces/http.mjs:2-39; errorStatus() falls back to 503 because the code does not match the 400 regex, and errorBody() replaces it with {error:"service_unavailable",category:"availability",retryable:true}.

     A client following the documented range thus receives a deterministic validation failure labelled as a transient outage and will retry forever; operators see false dependency outages, the very thing this commit's discovery change set out to isolate.

     Fix: map signal_grant_expiry to 400/409 in interfaces/http.mjs, and make the two bounds consistent (validate grantPrepare against the same head timestamp the adapter uses, or document/derive the API range as (head+60, head+30d]).

   • lowScheduler finishes a run as failed and releases the lane once the engine row is confirmed/reverted even though the hash was never attached to the API operation (signal_submit kept failing)reference/pulse-scheduler.mjs:49

     Before 7b62bd0 any chain-transactions row for the run's operation kept the run non-terminal (terminal=!signed&&(...)), so a hosted write whose signal_submit call to the network API failed kept retrying at 60 s until the hash was journaled. The new rule treats confirmed/reverted/cancelled engine rows as resolved and makes the run terminal on run.expiresAt<=now() or a listed code.

     But the engine hash reaches the API operation only through call("signal_submit") in reference/pulse-pipeline.mjs:45, which runs after publisher.step and throws an uncoded error on transport/5xx failure.

     The engine reports confirmed only after finality (~13 min on mainnet) while run.expiresAt can be as little as seconds away when the write is prepared (the pipeline checks run.expiresAt>now() just before signal_record_prepare), so a late write is routinely confirmed after run.expiresAt.

     If every signal_submit attempt from broadcast through that point failed (API origin or its RPC unavailable), one more failure after run.expiresAt makes terminal=true: the job finishes "failed" with error "reference_unavailable" and no transactionHash, the lane advances, and nothing ever retries signal_submit for that run.

     The signal-operations row stays "prepared" without a hash until it expires, no signal.record_confirmed event is emitted, and worker-health reports a failed run for a write that executed onchain; a reverted row is likewise reported as reference_unavailable instead of signal_transaction_reverted. Sequence continuity is unaffected because later runs read signal_latest from chain, and the hash remains in chain-transactions for manual recovery, hence low.

     Fix: count a confirmed/reverted engine row as resolved only once the API operation carries its hash (read signal-operations for run.write.operation.id and require transactionHash===signed.value.hash, or have the pipeline persist run.transactionHash from the engine before calling signal_submit and keep retrying while it is unattached). Merged from the permissions (low) and flow (medium) reports.

   • lowdiscovery reports permanent admission faults (signal_factory_changed, wrong_chain, signal_evidence_invalid, missing artifact, no chain client) as the transient signal_dependency_unavailablesrc/signals/index.mjs:165

     The catch-all added in 7b62bd0 special-cases three not_enabled codes and maps every other error to admission "unavailable" with a fixed reason. admission() can also fail with deterministic, operator-actionable, non-sensitive codes that no retry resolves: signal_factory_changed (adapters/signal-read.mjs:42-44: chainId mismatch, factory code hash changed, factory.executor() != config.executor), wrong_chain (:35), signal_evidence_invalid (adapters/signal-evidence.mjs: reviewed factory artifact does not reproduce the deployed code), artifact not_found/corrupt from artifacts.get, and signal_chain_unavailable (router has no client for the chain).

     All now look identical to an RPC blip in the public capabilities payload (src/access/index.mjs signalProfiles) and to worker-health consumers, so a misconfigured or tampered profile is advertised as "come back later" instead of being surfaced; the comment's claim that only "a chain dependency outage closes this profile" is not what the code does. Writes still fail closed with the precise code on the write paths, so this is a diagnostic gap, not a bypass.

     Fix: keep the generic reason for errors without a code (transport/RPC) and for signal_chain_unavailable/wrong_chain, and pass through the project's own coded admission failures (e.g. admission:"not_enabled", reason:error.code), which carry no RPC detail. Merged from the permissions (info) and flow (low) reports.

   • lowgrantRegister applies no inclusion margin and never consults chain time, so it prepares a registration intent for a grant that is seconds from (or already past) expiry and is guaranteed to revertsrc/signals/index.mjs:192

     This commit adds a 60 s chain-clock margin at signal_grant_prepare (adapters/signal-read.mjs:135) and at record preparation (:158), and the delta description says it "requires 60s inclusion margin on grant/record validity".

     The step that actually emits the transaction the publisher broadcasts, grantRegister -> chain.registerGrant (adapters/signal-read.mjs:143-150), checks only owner, authorityGeneration and the signature; the API-side guard on this line compares the grant expiresAt against the server clock with zero margin.

     The grant operation row lives 24 h (src/signals/index.mjs:103) while a grant may have been prepared with 61 s of life, so an intent can be handed out with one second left, or already expired on chain whenever the server clock is behind block time.

     ClausSignalStore.registerGrant reverts with InvalidGrant when g.expiresAt <= block.timestamp (contracts/src/ClausSignalStore.sol:107-110), so the intent can only burn the publisher's gas and then surfaces as signal_transaction_reverted.

     Fix: in grantRegister (or registerGrant) read the latest block and require terms.expiresAt > head.timestamp+60, returning signal_grant_expiry, mirroring the prepare-time check. (On this tree the API path is reached only after the first finding is fixed, because line 195 throws first; the chain-time part is shown through the adapter call grantRegister delegates to.)

     whole finding

     API path (mock chain, unit fixture rows, chain.grant returning {revoked:false}): grantPrepare with expiresAt = floor(now/1000)+3600, then set now() = expiresAt*1000-1000 (one second of life left) and call grantRegister("owner","p",{operationId, signature}).

     Expected: rejection with signal_grant_expiry (margin) like prepare.

     Actual: returns state "prepared" with the registration transaction.

     Chain path (Anvil, case 3 of test/scratch/grant-register-anvil.test.mjs): terms.expiresAt = head+61; signalChain.prepareGrant succeeds; mine 70 blocks at 1 s so head >= expiresAt; signalChain.registerGrant(signal,binding,grant,ownerSignature) resolves with transaction.from === publisher instead of rejecting; sending that transaction from the publisher with gas 300000 yields a receipt with status "reverted".

     Run from the repository root after cd contracts && forge build && cd .. && npm ci.
