Mechanism

The mechanism begins with a credentialed issuing authority producing an adaptation artifact whose authority credential is evaluated, through the five-property governance chain, against a declared role and a governance-policy-defined capability scope. An artifact, in this disclosure, is any unit of adaptation content that modifies the cognitive behavior of a consuming agent, including but not limited to parameter deltas, prompt templates, retrieval indices, and expert-routing tables, expressed through any of the disclosed adaptation-technique forms such as parameter-efficient fine-tuning artifacts, full-fine-tuning differential artifacts, prompt-adaptation artifacts, and retrieval-augmented-generation artifacts. The artifact carries a structured set of fields, including an artifact identifier, an adaptation-technique identifier, an artifact-content field, a capability scope specification, a compatibility specification, a licensing specification, a dependency specification, a certification record, a provenance-lineage record, an authority credential, a version identifier and version-lineage chain, and a cryptographic integrity attestation over the foregoing fields binding the artifact to its issuing authority credential.

When a consuming agent receives a candidate artifact for activation, the artifact is evaluated through several governance checks before it is permitted to take effect on the operational cognitive substrate. The authority credential and cryptographic integrity attestation are evaluated through the composite admissibility evaluator, which weighs the artifact's authority credential, capability scope, licensing specification, dependency satisfaction, and authority compatibility. The capability scope specification is checked against the consuming agent's deployment context to determine whether the artifact applies within the bounded range of cognitive contexts it declares. Sandbox pre-activation evaluation instantiates a sandboxed copy of the consuming agent's cognitive substrate, applies the candidate artifact, and produces a certification record covering compatibility assessment, performance preview, governance summary, and risk projection, together with the cryptographic attestation of the consuming agent's sandbox evaluator. The certification record and the activation are recorded in the consuming agent's lineage field, enabling downstream auditors to reconstruct the chain of derivations.

Only after the activation gate produces an affirmative outcome does the artifact enter live operation. A failure yields a governed refusal observation rather than silent rejection, so that the refusal itself is a first-class governed observation, attributable and admissible in downstream composition. Cascade deactivation completes the mechanism through the dependency-chain primitive: when a strict prerequisite artifact is deactivated, the cascade-deactivation mechanism deactivates dependent artifacts whose validity depends on the prerequisite, resolved through the transitive dependency closure recorded in the dependency-lineage record.

The mechanism, as disclosed in U.S. Provisional Application No. 64/049,409, is structurally distinct from prior model-update distribution because the artifact carries its authority credential, capability scope, certification record, and provenance-lineage record as governed fields rather than relying on out-of-band tooling. A consuming agent that activates an artifact without an admissible certification record produces an activation that downstream consumers can identify and refuse; the integrity of the mechanism therefore rests on the governance chain's insistence that every activation carry the certification record produced by sandbox evaluation, not on each agent's discipline.

Operating Parameters

The cryptographic integrity attestation is not bound to a specific primitive. The disclosure provides that the attestation may be produced under a digital-signature algorithm, a threshold-signature algorithm, a zero-knowledge attestation, a post-quantum attestation, or any equivalent cryptographic attestation mechanism supporting the governance-chain properties, and contemplates substitution of specific cryptographic primitives with equivalent post-quantum cryptographic primitives without altering governance-chain properties. The authority credential carries a temporal-scope specification of the credential's validity period; the disclosure does not fix particular validity durations.

The capability scope specification identifies the bounded range of cognitive contexts within which the artifact is governance-policy-defined to apply. During generation, the admissibility gate determines whether a candidate generation step falls within the capability scope of one or more currently active artifacts, performing a governance gate and a skill-domain-routing function simultaneously. An artifact whose scope does not encompass the current generation context is not routed to influence that step.

Sandbox evaluation operates against representative generation contexts drawn from the consuming agent's current task context, from governance-policy-defined standard evaluation suites, and from the consuming agent's experiential observation store. The evaluation produces a compatibility assessment identifying conflicts with currently loaded artifacts, a performance preview of the composed stack, a governance summary indicating licensing constraints, capability-scope boundaries, dependency satisfaction, and authority compatibility, and a risk projection. The resulting certification record is lineage-recorded and is admissible as input to subsequent composite admissibility evaluations at other consuming agents considering the same artifact. The mechanism additionally supports pre-certification, wherein a governance-credentialed certification authority runs the sandbox evaluation independently and publishes the certification record as a governed observation, and escalation to a deeper second-tier evaluation upon ambiguous or high-risk outcomes.

The provenance-lineage record identifies training inputs, training methodology, contributing authorities, and any antecedent adaptation artifacts from which the artifact was derived, supporting deterministic reconstruction of the artifact's provenance. Routing decisions, handoffs, dependency resolutions, and activation outcomes are recorded in the consuming agent's lineage field. Artifacts propagate through the governed mesh rather than requiring centralized distribution infrastructure, so that cross-device, cross-authority audits can reconstruct activation history.

Alternative Embodiments

One embodiment applies the artifact primitive across the disclosed adaptation-technique forms, including parameter-efficient fine-tuning artifacts, full-fine-tuning differential artifacts, prompt-adaptation artifacts, and retrieval-augmented-generation artifacts. A second embodiment produces federated adaptation artifacts, wherein a plurality of participants contribute training-data observations without raw training data leaving the participant's local environment, a secure-aggregation function combines local-adaptation-update observations into a federated adaptation artifact, and a federated-provenance-lineage recorder records participant count, per-participant contribution weights, aggregation method, and privacy-budget consumption in the artifact's provenance-lineage record. A third embodiment produces the cryptographic integrity attestation under a threshold-signature algorithm requiring a governance-policy-defined quorum of independent attesters, composing with multi-authority governance.

A further embodiment supports cross-model portability, wherein an adaptation artifact produced for a first base cognitive substrate is transferable to a structurally compatible second substrate through a compatibility evaluator and a parameter-remapping generator, with each portability determination and remapping operation recorded in the consuming agent's lineage field. A further embodiment maintains an always-active personal-adaptation layer throughout routing, excluded from the routing de-weighting mechanism so that it remains active across all generation contexts to preserve the consuming agent's individual adaptation continuity.

Composition with Other Primitives

Governed adaptation artifacts compose with the cascade-propagation primitive, where deactivation of an upstream artifact propagates through dependency relationships and produces refusals that are first-class governed observations, carried through the same observation channels used for any other admissibility decision. The result is that a deactivated or inadmissible artifact does not merely cease to operate, it produces an auditable trail of refusals that downstream consumers admit as evidence.

Composition with the governed marketplace of Chapter 22 supports artifact exchange under licensing specifications, where a composite licensing specification equal to the most restrictive intersection of source licensing specifications governs composed artifacts while their provenance lineage remains intact across the transfer. Composition with the health-monitoring primitives of Chapter 26 admits certification records into per-device and fleet-level health attestations, so that activation history contributes to operational fitness assessments. Composition with the settlement primitive of Chapter 20 supports cross-authority artifact exchange, where each side admits the other's artifacts under governed settlement.

Distinction from Prior Art

Prior machine-learning adaptation artifacts and prior model-update distribution artifacts are un-credentialed or carry only publisher-verification attestations without hierarchical trust semantics, and they are distributed without per-artifact training-data lineage. They do not bind a governance-policy-defined capability scope into the artifact as a machine-readable constraint, do not require admissibility evaluation against deployment context as a precondition for activation, and do not maintain provenance-lineage records that support cascade deactivation across dependent artifacts.

Prior artifacts are activated without pre-activation evaluation and compose through ad-hoc model-management tooling, whereas the present mechanism sandbox-evaluates each artifact prior to activation and composes across per-authority, per-dependency, and per-compatibility dimensions with governance-chain preservation. The present mechanism unifies the cryptographic integrity attestation, capability scope, sandbox pre-activation evaluation, certification record, and provenance lineage into a single primitive that other primitives compose with directly.

Failure Modes and Recovery

The mechanism contemplates several failure modes and their recovery paths. The first is attestation failure, in which the cryptographic integrity attestation does not verify against the asserted authority credential; recovery requires that the artifact be re-issued by an authority whose credential remains valid. The second is admissibility failure, in which the artifact's capability scope, licensing, dependency satisfaction, or authority compatibility is not admitted by the composite admissibility evaluator against the deployment context; recovery requires either narrowing the artifact at re-issuance or adjusting the deployment context's governance policy, both of which produce auditable observations.

The third failure mode is sandbox-evaluation failure, in which the activation gate produces a reject outcome based on the compatibility assessment, performance preview, governance summary, or risk projection during pre-activation evaluation; recovery requires either remediation of the artifact, adjustment of the evaluation contexts to better reflect intended deployment, or acknowledgement that the artifact is not suitable for the consuming agent. An ambiguous or high-risk outcome may instead escalate to a deeper second-tier evaluation rather than reject outright. The fourth is dependency failure, in which a strict prerequisite is unavailable, unlicensed, uncertified, or incompatible; recovery requires satisfying the prerequisite, accepting a governance-policy-defined equivalent-capability-scope alternative, or re-issuing the dependent artifact. In each case the failure observation is itself a governed observation, so that the operational record reflects not only the artifacts that activated but the artifacts that did not, and the reasons.
