Conformity Attestation: Verifiable Architectural Compliance

Mechanism

The mechanism comprises a declared cognitive standard, an attestation harness that exercises a running agent against that standard, a signing authority that endorses verification results, and an attestation artefact that is consumed by relying parties. The declared cognitive standard is a structured specification enumerating the architectural requirements the agent claims to satisfy: that confidence-governed execution is operational, that integrity tracking emits deviation signals, that affect-modulated training depth is honoured during any in-band learning, that pseudonymous operation is enforced at the behavioural-emission boundary, and so forth. Each requirement in the standard has a corresponding probe definition specifying how the requirement is to be exercised and what observable outcome confirms operational status.

The attestation harness is the active component. At verification time, the harness instantiates each probe against the running agent, supplying inputs designed to elicit observable behaviour that distinguishes a conforming implementation from a non-conforming one. For confidence governance, the harness submits inputs spanning the confidence range and confirms that low-confidence inputs are gated, deferred, or escalated rather than executed. For integrity tracking, the harness perturbs internal state and confirms that the perturbation is detected and reported through the governance signal channel. For pseudonymous operation, the harness attempts to read the affect store through the documented external interfaces and confirms that no affect value is returned. The harness records, for each probe, the input applied, the observable outcome, the timestamp of execution, and a cryptographic digest of the agent build identifier.

A critical design element of the harness is that probes are differential rather than declarative. The harness does not ask the agent whether confidence governance is operational; it submits inputs whose correct handling depends on confidence governance being operational and observes whether the handling is correct. A non-conforming agent that asserts conformity through self-report is detected because its observable behaviour fails the differential probe, regardless of what it claims about itself. This shifts the attestation from a trust-the-claimant model to a trust-the-procedure model, which is the principal source of the mechanism's robustness against adversarial agents.

The signing authority converts the harness output into an attestation artefact. The artefact specifies the standard against which verification was conducted, the version of the harness used, the agent build identifier, the per-requirement probe outcomes, the verification timestamp, and the validity window beyond which the attestation must not be relied upon. The artefact is signed under a key whose chain of trust is anchored to a root acceptable to the relying party. Tampering with any field invalidates the signature; reliance after the validity window expires is structurally distinguishable from reliance within the window because the artefact carries an explicit expiry.

Operating Parameters

Operating parameters of the disclosed mechanism include the granularity of the declared standard, the depth and duration of harness probing, the validity-window length, the signing-key custody arrangement, and the revocation policy for attestations issued against agent builds subsequently found to be non-conforming.

In one embodiment, the declared standard is decomposed into between ten and one hundred individual requirements, each with its own probe definition, permitting partial attestations in which an agent attests to a subset of the standard rather than the whole. Harness probing is parameterised by a per-probe input budget specifying the number and diversity of test inputs, with budgets scaled to the criticality of the requirement being verified. The validity-window length ranges from minutes, in deployments where agent state evolves rapidly and continuous re-attestation is feasible, to days, in deployments where the agent build is stable and re-verification is expensive.

The signing-key custody arrangement may be self-signed by the agent's own enclave, signed by an issuer operating the harness on behalf of the agent, or signed jointly under a threshold scheme requiring agreement among multiple verifiers. The revocation policy specifies how an issued attestation is invalidated before its natural expiry: by publication of a revocation entry in a signed registry, by inclusion of the agent build identifier in a deny list consulted by relying parties, or by issuer-side refusal to renew, depending on the trust model of the deployment.

Alternative Embodiments

In a first alternative embodiment, the attestation harness operates in-line with agent execution, performing continuous low-cost probing rather than periodic batch verification. Each external interaction triggers a small subset of probes, and the rolling outcome is summarised into a streaming attestation that relying parties consume alongside the interaction.

In a second alternative embodiment, the declared cognitive standard is itself versioned and the attestation artefact carries the standard version, permitting a relying party to verify not only that the agent conforms but that it conforms to the specific standard version the relying party requires. Migration between standard versions is mediated by issuer-side transition policies.

In a third alternative embodiment, attestation is composed across a pipeline of agents: each agent in the pipeline attests to its own conformity, and the pipeline as a whole carries an aggregate attestation that is valid only when every constituent attestation is valid. This embodiment supports trust propagation through multi-agent workflows without requiring the relying party to inspect each agent individually.

In a fourth alternative embodiment, the harness is implemented as a remote service that probes the agent over its standard external interfaces, requiring no privileged access to the agent's internal state. This embodiment trades off probe depth for deployment simplicity and is suited to ecosystems in which agents are operated by distrusting parties.

Composition

Conformity attestation composes with structural-validation primitives in the agent-schema family. Structural validation establishes that the agent's declared schema is internally consistent and matches the implementation; conformity attestation then asserts that the validated structure is operational at runtime. The two primitives together yield a chain of evidence linking the static declaration of an agent's architecture to a runtime guarantee that the architecture is actually exercised.

The mechanism further composes with confidence-governance, integrity-tracking, affect-modulated training, and pseudonymous-operation primitives by providing the verification surface that each of those primitives requires for external trust. In the case of pseudonymous operation in particular, conformity attestation provides the only acceptable external evidence: the affective state may not be read by counterparties, so the only way to establish that the privacy invariant is honoured is through an attestation harness that probes the agent's external interfaces and confirms structurally that no affect leakage occurs. Each such primitive defines what it means for its requirements to be operational; conformity attestation provides the harness through which that operational status is confirmed and the artefact through which the confirmation is conveyed to relying parties. The mechanism also composes with lineage primitives by emitting attestation events into the agent's lineage record so that the agent's history includes a verifiable account of when and against what standard it was attested.

Prior-Art Distinction

Prior-art remote-attestation systems, such as those built on trusted-platform modules, attest to the integrity of a software stack by measuring binaries and producing signed measurements of the boot sequence. The disclosed mechanism is distinguished by its focus on cognitive-architecture conformity rather than binary integrity: a TPM measurement confirms that the expected code is loaded, but does not confirm that the loaded code exhibits the behavioural properties of the declared cognitive standard. Conformity attestation actively probes for those behavioural properties and signs the observed outcomes.

Compliance-audit frameworks in the prior art rely on documentary evidence and periodic human review. The disclosed mechanism differs by automating the verification, by binding the attestation to a cryptographic signature rather than a human signature, and by enforcing a validity window that requires re-verification rather than treating compliance as a static property. The mechanism is further distinguished from generic API-conformance testing by its specific structural anchoring to a declared cognitive standard composed with the broader agent-schema family.

Disclosure Scope

The disclosure encompasses any verification mechanism that examines a running agent system against a declared cognitive standard, produces a cryptographically signed time-bounded artefact asserting per-requirement operational status, and is consumed by relying parties as a substitute for bilateral inspection, regardless of the specific structure of the standard, the specific implementation of the harness, or the specific custody arrangement of the signing authority. The scope includes batch and streaming embodiments, full and partial attestations, self-signed and third-party-signed artefacts, and embodiments in which the attestation is composed into multi-agent pipelines, accompanied by lineage events, or paired with revocation registries to support invalidation before natural expiry.
