Fail-closed verify-to-activation gate for ai-agent execution

Abstract

A fail-closed verify-to-activation control path enforces deployment logic for AI-agent execution. A commitment to an Immutable Constraint Chain (102) is anchored in an append-only verifiable log that publishes signed heads. At runtime, within an Encrypted Logic Vault (106), the system verifies freshness of a current signed head under a freshness policy, verifies inclusion of the commitment relative to the current signed head, and, upon head advance, verifies append-only evolution using a consistency proof. A licensing gate (112) verifies license tier and quorum and, upon success, authorizes minting of a short-lived, audience-bound permit token and recording of a permit record in an Immutable Arbitration Ledger (114). A valid, unexpired, and unrevoked permit identifier is required at a privileged intercept before device I / O or network egress; otherwise execution is denied with a structured disposition.

Embodiments described herein may be used with, or without, such related mechanisms.

[0005] The architecture may interoperate with external services such as cognition-origin verification, execution licensing, and behavior oversight. Such interoperability may use identifiers, permits, and audit records as described herein.III. FIELD OF THE INVENTION

[0006] The invention relates to secure control paths for Al-agent execution, logic-constraint enforcement, and permit-based actuation gating.

[0007] More specifically, it provides a layered control path that verifies logic constraints, signed-head freshness, inclusion, and append-only-evolution consistency, applies license-tier and quorum checks, and enforces verify-to-activation and permit-before-action semantics inside a trusted boundary prior to activation.IV. DEFINITIONS

[0008] Fail-closed means execution is blocked unless required verifications pass.

[0009] Disposition denotes a machine state selected from ALLOW, HOLD, QUARANTINE, DENY, ESCALATE. In the fail-closed case, the disposition is selected from HOLD, QUARANTINE, DENY, or ESCALATE (i.e., ALLOW occurs only on PASS).

[0010] Permit denotes an approval artifact minted on PASS and recorded as audit evidence; the permit identifier is required for subsequent actions. In some embodiments, a permit is represented as a permit token comprising the permit identifier and a digital signature, optionally including a key identifier and a signature-scheme identifier used for allowlisted verification (illustrative; non-limiting).

[0011] Append-only verifiable log denotes a system (e.g., transparency-style log or functionally equivalent accumulator) that publishes signed heads and supports inclusion and append-only-evolution (consistency) proofs including, illustratively, Merkle transparency logs, key-transparency / witness-cosigned logs, and ciyptographic accumulators.

[0012] CRA means trust-root authority; ROHS means root-of-hash sequence fingerprint of an agent or logic artifact.

[0013] ELV (Enciypted Logic Vault) encompasses trusted compute boundaries that enforce post-deployment immutability, including read-only -memory code paths or trusted execution environments with sealed memoiy pages; examples are illustrative and non-limiting.[0013A] Illustratively, the ELV MAY be realized using secure elements (SEs), TPM-anchored measurements / quotes (e.g., PCR-backed attestation), or measured-boot ROM paths; functionally equivalent trusted boundaries are included.

[0014] Verify-to-activation denotes performing one or more required verifications inside the ELV boundaiy prior to device I / O or network egress; failure to satisfy predicates yields a fail-closed disposition.

[0015] Signed head — a cryptographic summary of the append-only verifiable log’s state used for freshness and inclusion checks.

[0016] Inclusion proof — a proof that a commitment (e.g., an ICC commitment) is contained under a given signed head.

[0017] Append-only-evolution (consistency) proof — a proof that a newer head extends a prior head without reordering or deletion.

[0018] Freshness policy — a policy limiting the maximum age of the signed head used for inclusion checks; illustratively, the policy MAY specify a Maximum-Merge-Delay (MMD), where MMD exceedance maps to HOLD or DENY until continuity is proven.

[0019] Quorum signature (m-of-n) — a multi-signer approval threshold enforced by the licensing gate (GLG); insufficient quorum yields DENY.

[0020] Permit identifier — a unique identifier for a permit; absence, expiration, or revocation results in DENY (illustrative; non-limiting). In some embodiments, revocation or quarantine is indicated by a revocation beacon or a quarantine beacon recorded in the IAL (e.g., as a beacon record or token) and associated with the permit identifier (illustrative; non-limiting). In some embodiments, the beacon record MAY include integrity protection, such as aquorum-vote signature or other digital signature, to support tamper-evident propagation and offline verification (illustrative; non-limiting).

[0021] Behavioral profile — a compact tuple used for ICC comparison that includes at least a behavioral index, a temporal context, an instruction class, and an entropy-slope metric; the profile MAY further include features such as n-gram perplexity, an action-type risk score, and an instrumented tool-call count.

[0022] MIT (Mission Identity Template) — a machine-readable mission definition comprising a symbolic intention tree, a temporal purpose vector, and semantic clauses.

[0023] Drift index — an aggregate (e.g., exponential-moving-average or weighted sum) computed from rolling, windowed drift counters and compared to a policy threshold.

[0024] Delta-consistency — a replication property for IAL segments providing tamperresistant propagation; illustratively realizable via a version-vector protocol or Merkle-based inclusion / consistency proofs.

[0025] Attestation quote — evidence emitted by the ELV (e.g., measured-boot / TEE report) comprising a measurement / image hash, a version / PCR register set, and a signature / certificate chain for GLG validation.

[0026] Jurisdictional fingerprint — an identifier for a licensing / sovereign context used by GLG / IAL entries.

[0027] License tier — an execution class (e.g., Alpha / Beta / Gamma) used by GLG routing and quorum thresholds.

[0028] License-hash timestamp — a timestamp associated with a license hash used by GLG / IAL.

[0029] Audience-bound (permit) — binding of a permit to at least one of an agent identifier, tenant identifier, or mission identifier; use outside the audience maps to DENY.

[0030] Lease-based permit — a short-lived permit with time-to-live (TTL), refresh-by semantics; a missed refresh maps to HOLD, and if unremedied within a policy window, to DENY.

[0031] Concurrency-prevention tuple — a tuple derived from a nonce and a monotonic counter that denies concurrent reuse of a prior approval.

[0032] Signed-head identifier — an identifier for the signed head recorded in evidence (e.g., in IAL records).

[0033] Implementation note. References to particular operating systems, hypervisors, trusted execution environments, verifiable logs, or proof systems are examples only; functionally equivalent compute boundaries and evidence systems are included.[0033A] Computer-readable medium refers to non-transitoiy storage media; transitory signals per se are excluded.[0033B] Ciyptographic equivalence. References in this Specification to digital signatures, hash functions, accumulators, and vector-commitments include post-quantum (PQC) schemes and functionally equivalent constructions (e.g., lattice-, hash-, code-, or multivariate-based primitives). Algorithm names are illustrative; function controls.[0033C] Evidence-only interoperability. The term “evidence-only” (as used herein, for example in relation to certain artifacts) denotes that an artifact or integration may be used for logging, audit, compliance, correlation, or reporting and that predicate evaluation for permit issuance does not depend on the presence or absence of that artifact or integration, unless expressly stated.V. BACKGROUND OF THE INVENTION

[0034] Autonomous Al can self-modify and regenerate logic, creating risk of unintended behavior.

[0035] Perimeter controls and post-execution audits are insufficient when behavior can mutate before observation.

[0036] A runtime control path that binds verification to activation is required to prevent drift, recursion-based privilege escalation, and replay / mimicry of prior approvals.VI. SUMMARY

[0037] NOVACOV is a fail-closed, runtime execution gate that relocates verification into the execution path and binds verification state to activation. At deployment, agent logic is sealed as an Immutable Constraint Chain (ICC) anchored in an append-only verifiable log. At runtime — inside a read-only ELV boundaiy — the system: (i) confirms inclusion relative to a current signed head under a freshness policy and validates append-only-evolution (consistency) proofs on head advance; (ii) constructs a behavioral profile (including at least a behavioral index, temporal context, instruction class, and entropy-slope metric) and compares it to the ICC; (iii) checks purpose alignment against a machine-readable Mission Identity Template (MIT); and (iv) verifies license tier and m-of-n quorum at a licensing gate (GLG) (optionally validating an ELV attestation quote).[0037A] Only on PASS does the gate mint a permit and record it as audit evidence; the permit identifier is required prior to device I / O or network egress, enforced at a driver, firmware, or hypervisor intercept. Otherwise the gate returns a structured disposition (HOLD, QUARANTINE, DENY, ESCALATE). Each evaluation is bound to a nonce and a monotonic counter (anti-replay), and outcomes are written to an Immutable Arbitration Ledger (IAL) with delta-consistency across replicas. These mechanisms alter the operation of the computer itself by interposing a trusted, pre-I / O activation gate that denies execution absent verified freshness, consistency, license quorum, and permit presence, thereby preventing actions the machine would otherwise take.[0037B] Operational posture. Implementations may enhance safety and accountability by enforcing verify-to-activation, permit-before-action, and portable evidence without altering application logic.

[0038] Technical effects & posture. The architecture improves computer operation by (a) moving verification inside a trusted boundaiy before activation, (b) enforcing freshness / consistency predicates at runtime, (c) requiring permit-before-action, and (d) providing portable evidence (IAL) for compliance, audit, and licensing — without depending on post-hoc logs alone.[0038A] Binding verification state to activation reduces time-of-check / time-of-use hazards by gating prior to device I / O or network egress.[0038B] Implementation note. Appendix B provides example artifacts and verifier steps that some implementations may use.VII. SYSTEM ARCHITECTURE OVERVIEW

[0039] NOVACOV comprises three enforcement domains: Immutable Logic Constraint, Purpose Integrity Verification, and Sovereign Execution Binding.[0039A] The architecture enforces fail-closed gating: execution is denied unless all predicates pass; denials return structured dispositions and are recorded as evidence.1) Immutable Logic Constraint

[0040] All behavioral logic is encoded at deployment into an ICC 102, ciyptographically signed by a CRA.

[0041] Proof of freshness. A commitment to the ICC is anchored to an append-only verifiable log that publishes signed heads; at runtime the system confirms inclusion relative to a current signed head under a freshness policy and validates append-only-evolution (consistency) proofs upon head advance.[0041A] In some embodiments, the signed head is co-signed by one or more independent witnesses, and runtime verification includes validating at least one witness co-signature.

[0042] In some deployments, inclusion and consistency MAY be verified across two or more independent append-only verifiable logs to improve fault isolation and cross-sovereign continuity. If a head conflict or disagreement is detected between the independent logs, the system maps the request to HOLD until continuity is proven and records a conflict record in the IAL.

[0043] Anti-replay. Each evaluation binds a nonce and monotonic counter to the request.

[0044] At runtime, each inference request is translated into a behavioral profile and compared to the ICC by a Behavioral Hash Validator (BHV) 104.

[0045] Deviation beyond a configured threshold triggers DENY or HOLD (short-permit), and may trigger QUARANTINE.

[0046] Verification occurs inside an Encrypted Logic Vault (ELV) 106, a read-only boundary that prevents post-deployment logic mutation.

[0047] The ELV gates verify-to-activation, preventing activation prior to device I / O or network egress until the required predicates pass.2) Purpose Integrity Verification

[0048] All agent outputs are filtered through a Purpose Enforcement Kernel (PEK) 108, which stores the agent’s intended objectives in a machine-readable MIT.

[0049] The PEK compares outputs to the MIT using symbolic constraints and temporal drift indices; an RMDM drift-monitor subsystem 110 maintains rolling windows andsuspends privileges on threshold breach.

[0050] Failing requests receive DENY or QUARANTINE and are logged for arbitration. 3) Sovereign Execution Binding

[0051] Logic-approved requests are routed through a licensing gate (GLG) 112 to confirm license tier and quorum (m-of-n), and MAY validate an ELV attestation quote prior to permit issuance.

[0052] On PASS, the system mints a permit and records a permit record in an IAL 114 with identifiers for at least the ICC commitment, license tier, and verification result.

[0053] IAL entries MAY further include a permit identifier and a signed-head identifier, and MAY be replicated under delta-consistency (e.g., version-vector or Merkle) for tamperresistant propagation.

[0054] The permit identifier is required for subsequent actions; absence, expiration, or revocation results in DENY.

[0055] Permits MAY be lease-based (time-to-live (TTL), refresh-by) and audience-bound (e.g., agent / tenant / mission); a missed refresh maps to HOLD and, if unremedied within a policy window, to DENY.

[0056] GLG enforces tiered routing (e.g., Alpha, Beta, Gamma) and m-of-n quorum signatures as configured.

[0057] Dispositions include: ALLOW — all predicates pass; permit minted. HOLD — awaiting proof of continuity or quorum; auto-expires absent proof of continuity.QUARANTINE — deviation or mutation suspected; investigation required. DENY — predicate fails (e.g., ICC mismatch, ELV mutation, PEK misalignment, license mismatch, replay / mimicry). ESCALATE — route to arbitration under policy.

[0058] Firewall integration. NOVACOV may be deployed as a logic-layer gate within a multi-layer safety stack, and may interoperate with upstream and downstream services (e.g., cognition-origin verification, licensing, behavior oversight) using identifiers and audit records.

[0059] Auxiliaiy safeguards — e.g., OSDE 116 (replay / mimicry denial) and GOCT 118 (termination beacons) — may provide additional checks, evidence, or escalation paths under policy.

[0060] Portfolio boundary. This disclosure concerns fail-closed logic-execution gating (ICC / BHV / ELV / PEK / GLG). In some embodiments, the disclosed gate is deployed alongside additional mechanisms (e.g., model-loading admission controls, per-frame overlay gating, RTC presence / clone attestation), and the system may exchange identifiers or audit records with those mechanisms.[0060A] A permit MAY include a ciyptographic signature over one or more permit fields (e.g., ICC head identifier, signed-head identifier, license-tier identifier, expiration, audience binding, nonce, monotonic counter).VIII.

[0074] Referring to FIG. 1, ICC 102 stores the deployment logic commitment signed by a CRA. At runtime, BHV 104 translates each request into a compact profile (behavioral index, temporal context, instruction class, entropy-slope metric) and compares it to the ICC.

[0075] If deviation exceeds a configured threshold, the request receives DENY; otherwise processing continues and an access log is written. Verification of freshness and inclusion relative to a current signed head, verification of append-only-evolution (consistency) proofs upon head advance, and anti-replay binding are further described in

[0041] -

[0044] .

[0076] Referring to FIG. 2, the BHV 104 constructs, for each request, a compact profile comprising a behavioral index, a temporal context, an instruction class, and an entropy-slope metric and compares the profile to the ICC 102 via a delta-threshold comparator as illustrated. Deviations beyond configured thresholds yield the dispositions described in

[0057] . The profile MAY further include, for example, n-gram perplexity, an action-type risk score, and an instrumented tool-call count. The comparator executes within the ELV 106 context shown in FIG. 3; the optional profile extensions are illustrative and non-limiting.

[0077] Referring to FIG. 3, the ELV 106 encloses the BHV compare path and is read-only post-deployment; attempts to mutate sealed logic are denied and mirrored to the IAL 114 for audit. Illustratively, the ELV gates verify-to-activation by preventing activation prior to device I / O or network egress until required predicates pass.

[0078] Illustratively, the ELV MAY expose an attestation quote (e.g., measured-boot or TEE report) that is validated by the GLG prior to permit issuance; a quote MAY include a measurement / image hash, a version / PCR register set, and a signature / certificate chain for verification. Valid and invalid ELV access events MAY be mirrored to the IAL with at least an event type, a ROHS fingerprint, a signed-head identifier, and a result code.

[0079] Signed-head freshness and append-only-evolution (consistency) proofs are enforced at runtime as preconditions to execute; anti-replay binds a nonce and a monotonic counter to each evaluation. These freshness / inclusion and consistency verifications are performed withinthe ELV boundary as part of verify-to-activation. The nonce and monotonic values MAY jointly act as a concurrency-prevention tuple to deny simultaneous reuse across threads or processes. B. PEK / MIT / RMDM

[0080] Referring to FIG. 4, PEK 108 verifies mission alignment against the MIT (symbolic intention tree, temporal purpose vector, semantic clauses). Aligned outputs may proceed toward GLG 112 (see FIG. 6); misaligned outputs map to QUARANTINE or DENY and are mirrored to IAL 114 with an alignment result field.

[0081] A Purpose Alignment Engine computes constraint satisfaction; failing outputs are quarantined and recorded. PEK 108 MAY emit a drift index to RMDM 110 to update rolling counters and MAY mirror an alignment result (and optional MIT revision identifier) to IAL 114.

[0082] Referring to FIG. 5, RMDM 110 maintains rolling, windowed drift counters and computes a drift index from the windows (e.g., an exponential-moving-average or weighted sum); the index is compared to a policy threshold. Upon a threshold breach, RMDM 110 suspends privileges by preventing permit issuance, revoking an active permit, or both, thereby causing subsequent agent actions to fail closed prior to device I / O or network egress absent a valid permit identifier, and arbitration is triggered via TAM 122; otherwise operation continues. On each update, RMDM 110 MAY mirror evidence to IAL 114 including at least a window identifier, a violation count or drift index value, the threshold used, and the resulting action. Drift updates MAY be emitted by PEK 108 (e.g., misalignment events), and the window scheme and aggregator are illustrative and non-limiting. C. GLG / PERMIT / IAL

[0083] Referring to FIG. 6, GLG 112 checks license-hash timestamp, jurisdictional fingerprint, license tier, and quorum. Illustratively, GLG 112 enforces a quorum signature threshold (m-of-n) and MAY validate an ELV attestation quote prior to permit issuance.

[0084] On PASS, a permit identifier is minted and recorded in IAL 114 and is required for subsequent actions; on mismatch, the request is blocked and escalated via TAM 122.

[0085] IAL 114 records permits, dispositions, and audit evidence to support accountability. IAL entries may include ROHS fingerprint, CRA lineage, license-hash timestamp, alignment result, drift score, and quorum-vote signature. Delta-consistency ensures tamper-resistant propagation; violations trigger revocation and quarantine beacons. Delta-consistency MAY be realized, for example, via a version-vector protocol or a Merkle-based inclusion / consistency proof mechanism. IAL entries may also include cross-rail references (e.g., sensor-receipt identifiers from an ingress rail or compositor-receipt identifiers from an overlay rail) to support correlation across enforcement boundaries.

[0086] IAL entries MAY further include a permit identifier and a signed-head identifier.

[0087] Referring to FIG. 7, the IAL 114 organizes permit and denial records and may include at least a timestamp, ROHS fingerprint, license-tier identifier, license-hash timestamp, alignment result, drift score, and quorum-vote signature, with delta-consistency across replicas for tamper-resistant propagation.

[0088] The permit identifier is required for subsequent actions by the agent; absence, expiration, or revocation results in DENY. HOLD dispositions auto-expire absent proof of continuity. Illustratively, a permit MAY be lease-based (time-to-live (TTL), refresh-by) and audience-bound (e.g., agent / tenant / mission identifiers); a missed refresh maps to HOLD and, if unremedied within a policy window, to DENY. D. OSDE / GOCT

[0089] Referring to FIG. 8, OSDE 116 rejects replay or mimicry attempts using signatureentropy correlation; repeated events are quarantined and flagged. Illustratively, OSDE MAY compute a token-level surprisal slope within a window of size W and / or a windowed entropy variance (jitter allowance), and evaluate its correlation with a deny-histoiy vector to detect replay / mimicry patterns; thresholds are policy-defined. OSDE 116 MAY maintain a repeat counter over a policy window, and MAY escalate to GOCT 118 when the counter or severity crosses a policy threshold.

[0090] Referring to FIG. 9, GOCT 118 halts execution across connected nodes upon override breach; termination beacons prevent resurrection attempts. Actions are logged in IAL 114. A termination beacon MAY include a lockdown tag and scope metadata (e.g., node set, time), and clearance MAY require arbitration via TAM 122; mirror entries are written to IAL 114. E. SALEM / TAM / SEF

[0091] Referring to FIG. 10, SALEM 120 shows the end-to-end control path(ICC->BHV / ELV->PEK / RMDM->GLG->permit). SALEM 120 is an overview map illustrating how permits and dispositions can be recorded in IAL 114.

[0092] Referring to FIG. 11, TAM 122 routes by tier and issues a verdict (Permit / Deny / Suspend) with fallback as configured; verdicts are mirrored to IAL 114.[0092A] In some embodiments, TAM 122 receives, from the verify-to-activation gate (e.g., ICC / BHV / ELV / PEK / GLG), an event record associated with a structured disposition (e.g., ESCALATE or QUARANTINE) and selects an arbitration tier to generate a verdict selected from Permit, Deny, or Suspend. The verdict MAY be recorded in IAL 114 as a verdict receipt comprising at least an evidence hash and an evidence signature. Illustratively, the evidence hash is computed over a canonicalized representation that includes at least: (i) the event record, (ii) the verdict, and (iii) a context label, and the evidence signature is generated over the canonicalized representation; the verdict receipt MAY further bind one or more of: a permit identifier, a signed-head identifier, a license-tier identifier, a jurisdictional fingerprint, or a lockdown tag associated with GOCT 118. In some embodiments, clearing a GOCT lockdown tag requires validating a corresponding verdict receipt recorded in IAL 114.

[0093] Referring to FIG. 12, SEF 124 optionally applies ethics / mimicry pattern checks at final egress to label and, where policy permits, filter / redact outputs. In some embodiments, SEF 124 records egress-related audit artifacts in IAL 114.[0093A] In some embodiments, SEF 124 is placed at a final egress boundaiy prior to release to an external recipient (e.g., an application response boundaiy, an API gateway boundaiy, a transport-layer egress boundaiy, a device-layer egress boundaiy, or a user-interface output boundary). SEF 124 generates an egress label by applying at least one ethics or mimicry pattern check to an agent output; illustratively, the egress label comprises at least a machine-readable reason code and a severity value. Where policy permits, SEF 124 selectively filters or redacts at least a portion of the agent output based at least in part on the egress label to produce a released output. SEF 124 MAY record, in IAL 114, an evidence-only egress artifact comprising at least the egress label, and optionally one or more digests (e.g., a digest of the agent output prior to filtering / redaction and / or a digest of the released output) and optionally one or more of: the permit identifier, the signed-head identifier, or an IAL record reference, such that gate predicate evaluation remains independent of the presence or absence of the evidence-only egress artifact.X. INDUSTRY APPLICATIONS

[0094] Air-gapped or mission-critical AGI (ICC commitment; ELV read-only; GLG quorum).

[0095] Public LLM agents (BHV drift guard; PEK alignment; RMDM suspension).

[0096] Cross-sovereign deployments (GOCT cascade; IAL audit; tier routing).

[0097] Multi-tenant cloud & accelerator fleets. Audience-bound, lease-based permits (time-to-live (TTL), refresh-by) for tenant / mission scopes; permit identifier required before egress; evidence mirrored to IAL 114 with jurisdictional fingerprint, license-hash timestamp, quorum-vote signature.

[0098] Financial & regulated workloads. GLG 112 enforces m-of-n quorum and jurisdictional fingerprint before compute; IAL 114 retains signed-head identifier, alignment result, drift score for audit / attestation.

[0099] Safety-critical robotics / edge. GOCT 118 termination beacons halt propagation on breach; OSDE 116 denies replay / mimicry; permits required for actuation (e.g., transmission on an industrial fieldbus); lockdown evidence stored in IAL 114.

[0100] Cross-sovereign data residency. Inclusion / consistency verified across independent append-only logs; delta-consistency across replicas for tamper-resistant propagation.XL BEST MODE IMPLEMENTATION

[0101] A preferred mode deploys NOVACOV as the logic-layer gate integrated with cognition-origin verification, license permission, and oversight services.

[0102] NOVACOV binds verification to activation with fail-closed dispositions and portable permits, preventing post-deployment logic mutation, replay, and unlicensed execution.

[0103] Freshness policy (illustrative). Configure a Maximum-Merge-Delay (MMD); heads exceeding MMD map to HOLD or DENY until continuity is proven.

[0104] Attestation. ELV 106 emits an attestation quote (measurement / image hash, PCR set, signature / cert chain) validated by GLG 112 prior to permit issuance.

[0105] Replication. IAL 114 replicates with delta-consistency (e.g., version-vector or Merkle proofs); violations trigger revocation / quarantine beacons.

[0106] Permit lifecycle. Lease-based permits with refresh windows; audience-bound (agent / tenant / mission). Missed refresh -> HOLD, unremedied -> DENY.[0106A] Governance and oversight. Implementations may distribute control by configuring GLG 112 with an m-of-n quorum among independent parties, maintain transparency by anchoring IAL 114 entries to signed heads, and provide appeal / clearance through TAM 122 and policy-bound GOCT 118 procedures.XII. EVIDENCE & COMPLIANCE INTEROPERABILITY

[0107] IAL evidence profile. Records MAY include permit identifier, signed-head identifier, license-tier identifier, license-hash timestamp, alignment result, drift score, quorum-vote signature, and jurisdictional fingerprint.[0107A] Transparency reporting. Operators may publish aggregated, privacy-preserving statistics (e.g., ALLOW / HOLD / DENY / QUARANTINE / ESCALATE counts, TAM outcomes, GOCT events) derived from IAL 114 to support external audit and oversight.[0107B] Canonicalization & context. In some embodiments, permit and IAL artifacts are signed over a canonicalized representation with an explicit context label (e.g., “NOVACOV / permit / vl”), and validators reject artifacts whose canonicalization or context does not match a configured value.[0107C] Evidence interoperability. Implementations may interoperate with transport or device-layer mechanisms that forward or mirror identifiers and audit references (e.g., permit identifier or signed-head identifier) for compliance and audit. See Appendix B for illustrative JSON artifacts and verification steps; field names are illustrative and do not limit functionality.

[0108] Permit-before-action. Subsequent actions require the permit identifier; absence / expiration / revocation results in DENY; HOLD auto-expires absent proof of continuity.

[0109] Audit granularity. ELV access events MAY mirror event type, ROHS fingerprint, signed-head identifier, and a result code; PEK and RMDM MAY mirror alignment result, optional MIT revision identifier, drift index and threshold.

[0110] Cross-jurisdiction posture. For multi-region deployments, delta-consistency across replicas ensures tamper-resistant propagation of approvals / denials; inclusion / consistency proofs MAY be verified against independent logs.XIII. DEPLOYMENT & SCALABILITY

[0111] ELV placement. Implement ELV 106 using read-only ROM paths or TEE-sealed pages; the BHV compare and freshness / consistency proofs execute inside the ELV boundary.

[0112] Latency budgets. Freshness / inclusion and consistency proofs are enforced at runtime; policy-tunable MMD and quorum thresholds allow balancing latency and assurance.

[0113] High availability. IAL replicas across failure domains with version-vector or Merklebased proofs; GOCT 118 provides fast-fail safety when escalated.

[0114] Observability. Components MAY emit counters / labels (e.g., permit PASS / F AIL, HOLD expiration, OSDE repeat counter, GOCT lockdown tag) to support audit without altering gate semantics.[0114A] Illustratively, verifying a permit or permit token MAY occur at privileged execution hook points, including a kernel-mode driver path prior to a doorbell write or a queue submission to an accelerator, a device-firmware microcode path prior to dispatch, or a hypervisor intercept path prior to a virtual-machine exit or network egress. In such embodiments, the hook validates the permit token’s cryptographic signature (e.g., using a key identifier and a signature-scheme identifier under a configured allowlist of signature schemes) and enforces fail-closed dispositions absent a valid permit (illustrative; nonlimiting). Illustratively, a doorbell write MAY comprise a write to a host-visible doorbell interface (e.g., a memoiy-mapped doorbell location, such as a doorbell register) that signals availability of work, and a queue submission MAY comprise enqueuing, into a queue structure used for dispatch (e.g., a submission queue), a queue entry comprising parameters for the requested actuation (sometimes referred to as a work descriptor) (illustrative; nonlimiting).XIV. CONFIGURABILITY & ADOPTION PROFILES

[0115] Policy knobs. MMD, quorum (m-of-n) threshold, permit lease duration / refresh window, audience binding scope, drift windows, and OSDE thresholds are policy-defined.

[0116] Gradual rollout. Operators may enable audit logging or mirroring first, then require permit-before-action, and finally enable GOCT escalation for designated tiers.

[0117] Interoperation boundary. Upstream cognition-origin verification and downstream license enforcement may be implemented as interoperable services alongside the disclosed gate; embodiments may exchange identifiers or audit records with such services.APPENDIX A — GLOSSARYPreface.

This Appendix provides example JSON artifacts and verification steps that an implementation may use to realize runtime gating and audit flows. Field names and encodings are examples; functionally equivalent structures are included. Conventions. JSON values are UTF-8. Timestamps are ISO-8601 with “Z”. Integers are unsigned unless noted.

In some embodiments, a transparency report includes a signed report header that binds at least: (i) a reporting-period identifier, and (ii) one or more signed-head identifiers and, optionally, one or more log identifiers used to derive the aggregated, privacy-preserving statistics. Illustratively, the signed report header is generated as a signature over a canonicalized representation that includes a context label (e.g., "NOVACOV / report / vl"), and validators reject a report header whose canonicalization or context label does not match a configured value.[B08B] Implementation note (non-limiting). The artifacts above support audit, interoperability, and adoption. They do not alter the claim-recited preconditions: signed-head freshness plus consistency proofs inside ELV, permit-before-action, GLG quorum, anti-replay, and fail-closed dispositions. Field names are illustrative; function controls. See Appendix C for additional illustrative extensions, including capability-scoped permits, budget enforcement, and permit-consumption evidence.APPENDIX C — Capability-Scoped Permits, Budget Enforcement,and Permit-Consumption Evidence[C01] Capability scope. In some embodiments, a permit token is capability-scoped by cryptographically binding an allowed capability scope specifying one or more permitted actuation classes and / or one or more permitted tool or endpoint identifiers. A privileged intercept denies a requested actuation that is outside the bound capability scope, thereby enforcing permit-before-action at a fine granularity (e.g., per tool call, per network destination, per device command).[C02] Example capability fields. An allowed capability scope may include one or more of: (i) an actuation-class identifier (e.g., "network-egress", "accelerator-dispatch","fieldbus-actuation") ; (ii) an API or tool identifier; (iii) a network destination identifier (e.g . ,hostname, IP prefix, port, protocol); (iv) a device address range or command identifier; or (v) a data-residency or jurisdiction label.[C03] Budget-bound permits. In some embodiments, the permit token binds a resource budget (e.g., compute time, accelerator time, number of tool calls, network bytes, or actuator energy) and the privileged intercept decrements a remaining budget per permitted actuation. Upon budget exhaustion, the intercept maps the request to HOLD or DENY until a renewed permit is obtained, and records the outcome in the IAL.[C04] Signature-scheme and key allowlisting. In some embodiments, a permit signature object includes a signature-scheme identifier and a key identifier. Validators reject a permit whose scheme identifier or key identifier is outside a configured allowlist. The allowlist may include at least one post-quantum signature scheme.[COS] Permit-consumption record. In some embodiments, the privileged intercept writes, to the IAL, a permit-consumption record for each requested actuation that includes at least the permit identifier and an outcome selected from ALLOW, HOLD, QUARANTINE, DENY, or ESCALATE. The record may further include a result code, an actuation identifier, aremaining-budget value, a signed-head identifier, and an evidence hash and evidencesignature.[C06] Secure time / rollback. Freshness policy MAY use a secure time source or secure monotonic counter; detected rollback maps to DENY or QUARANTINE and MAY berecorded in the IAL.[C07] Example snippets. Permit token additions (illustrative):{"capability_scope" : {"actuation_classes" : ["network-egress"]}, "budget" : {"net_bytes" : 200000},"signature" : {"alg" : "Ed25519", "kid" : "vendor-key-2025-Q3", "sig" : " . . ."} }Permit-consumption record (illustrative):{"event_type" : "ALLOW","permit_id" :"actuation" : "network-egress","result_code" : "ok","remaining_budget" : {"net_bytes" : 180000},"evidence_hash" :"evidence_signature" : " . . ."}

The apparatus of claim 30, wherein the permit token cryptographically binds a resource budget selected from at least one of: a compute-time budget, an accelerator-time budget, a network-byte budget, a tool-call budget, or an actuator-energy budget, and wherein theapparatus decrements a remaining budget value per permitted actuation and maps budget exhaustion to HOLD or DENY.

35. The apparatus of claim 30, wherein the digital signature is accompanied by a signaturescheme identifier and a key identifier, and wherein verifying comprises selecting a verification key based on the key identifier and rejecting the permit token when the signature-scheme identifier is outside a configured set of allowed signature schemes or when the key identifier is outside a configured set of allowed key identifiers, the configured set of allowed signature schemes including at least one post-quantum signature scheme.

36. The apparatus of claim 30, further configured to record, to the IAL, a permit-consumption record that includes at least the permit identifier and an outcome selected from ALLOW, HOLD, QUARANTINE, DENY, or ESCALATE, and wherein the permit-consumption record further includes at least one of: a machine-readable result code, an actuation-class identifier, or a remaining-budget value.

37. A computer-implemented method of fail-closed gating for an Al agent, comprising: (a) encoding deployment logic into an Immutable Constraint Chain (ICC) and anchoring a commitment to the ICC in an append-only verifiable log that publishes signed heads; (b) at runtime, within a read-only Enciypted Logic Vault (ELV), (i) verifying freshness of a current signed head under a freshness policy, (ii) verifying inclusion, relative to the current signed head, of the commitment to the ICC, and (iii) upon head advance, verifying append- only-evolution (consistency) from a previously observed signed head; (c) verifying license authority at a licensing gate (GLG) including a license-tier check and an m-of-n quorum signature threshold; (d) responsive to (b) and (c) passing, minting a short-lived, audiencebound permit, recording a permit record in an Immutable Arbitration Ledger (IAL), and requiring a valid, unexpired, and unrevoked permit identifier prior to any device I / O or network egress; otherwise failing closed with a structured disposition selected from HOLD, QUARANTINE, DENY, or ESCALATE, wherein (i) absence, expiration, or revocation of the permit identifier results in DENY, and (ii) each evaluation binds a nonce and a monotonic counter to form a concurrency-prevention tuple that is rejected upon reuse; and (e) enforcing the requirement of (d) at an implementation hook selected from: (i) a kernelmode driver path prior to doorbell or queue submission to an accelerator, (ii) a devicefirmware microcode path prior to dispatch, or (iii) a hypervisor intercept path for VM-exit or network egress, thereby denying a requested actuation absent a valid permit identifier.

38. The method of claim 37, further comprising validating at least one witness co-signature on the current signed head prior to inclusion or consistency checks.

139. The method of claim 37, wherein two independent append-only verifiable logs are required and a head conflict between the logs maps to HOLD with a conflict record in the IAL.

40. A non-transitoiy computer-readable medium storing instructions that, when executed, cause one or more processors to perform the method of claim 37.

41. The system of claim 1, wherein the system exports, for compliance or audit, an evidence-only artifact comprising at least the permit identifier and the signed-head identifier, and wherein predicate evaluation for permit issuance remains independent of presence or absence of the evidence-only artifact.
