Mechanism and Primitive Description
An adaptation artifact is evaluated before activation by a sandbox evaluation mechanism. A sandboxed-substrate isolator instantiates a sandboxed copy of the consuming agent's cognitive substrate, separate from the operational cognitive substrate. An evaluation-context generator produces 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. A composition executor applies the candidate adaptation artifact to the sandboxed substrate, and the evaluator exercises it against those contexts. Because the copy is separate from the operational substrate, the evaluation does not affect production behavior.
The evaluation produces a compatibility assessment identifying conflicts with currently loaded artifacts on the operational substrate, a performance preview producing sample outputs of the composed stack, a governance summary indicating licensing constraints, capability-scope boundaries, dependency satisfaction, and authority compatibility, and a risk projection associated with activation. An activation-gate controller produces an admit-or-reject outcome based on the composite of these evaluations. The outcome is written into a certification record recorded in the artifact's certification field, comprising the sandbox-evaluation timestamp, the consuming-agent identifier under which the evaluation was performed, the evaluation-context set applied, the compatibility assessment result, the performance preview result, the governance summary result, the risk-projection result, the activation-gate outcome, and the cryptographic attestation of the consuming agent's sandbox evaluator. The certification record is lineage-recorded and is admissible as input to subsequent composite admissibility evaluations at other consuming agents considering the same artifact.
The evaluation depth is graded. The mechanism supports escalation to deeper evaluation upon detection of ambiguous or high-risk outcomes: a first-tier fast sandbox evaluation that produces an admit-or-reject outcome with elevated uncertainty triggers a second-tier deeper evaluation with expanded evaluation contexts, longer evaluation duration, and stricter evaluation criteria. The escalation path is governance-policy-configurable per deployment and per adaptation-artifact class.
Operating Parameters and Engineering Envelope
The evaluation contexts are drawn from three sources: the consuming agent's current task context, governance-policy-defined standard evaluation suites, and the consuming agent's experiential observation store. Drawing from current task context favors realism for the agent's present work; drawing from standard evaluation suites favors comparable coverage across agents; drawing from the experiential observation store grounds the evaluation in conditions the agent has actually encountered. The evaluator's outputs span the four assessments produced by the mechanism: compatibility with currently loaded artifacts, a performance preview of the composed stack, a governance summary covering licensing, capability scope, dependency satisfaction, and authority compatibility, and a risk projection.
Sandbox isolation rests on instantiating a sandboxed copy of the consuming agent's cognitive substrate, separate from the operational cognitive substrate, so that the candidate artifact is applied and exercised without acting on production. The first-tier evaluation is fast; deeper evaluation, when triggered, runs with expanded evaluation contexts and a longer evaluation duration. The disclosure states these as graded, governance-policy-configurable behaviors rather than fixed latency or resource figures.
The mechanism additionally supports pre-certification. A governance-credentialed certification authority executes the sandbox evaluation independently of any specific consuming agent and publishes the resulting certification record as a governed certification observation consumable by any consuming agent considering the artifact. A consuming agent that admits a pre-certification governed observation through the composite admissibility evaluator may optionally admit the artifact without re-running the sandbox evaluation on its local substrate, subject to governance-policy-defined pre-certification-trust parameters. The certification record is admissible as input to the composite admissibility evaluations of other consuming agents considering the same artifact.
The activation-gate outcome is not a standalone verdict. Because the certification record is lineage-recorded and admissible as input to the composite admissibility evaluations of other consuming agents, a passing record at one agent informs, but does not dictate, the activation decision at another. The escalation path provides the depth control: where a first-tier outcome carries elevated uncertainty, the second-tier evaluation applies stricter criteria before an admit outcome is reached.
Alternative Embodiments
A firmware-update embodiment follows the mesh-distributed propagation pattern with the addition of a sandboxed execution environment of the receiving device that verifies the update does not violate governance policy; a firmware update failing sandbox evaluation is not applied and is recorded in the receiving device's lineage field together with the sandbox-evaluation output. A composite-artifact embodiment requires a fresh certification record and a fresh sandbox evaluation of a merged artifact prior to activation, rather than inheriting the certifications of its source artifacts. A cross-model-portability embodiment invokes the sandbox evaluation against the target environment, producing target-environment-specific evaluation results that feed a confidence adjustment for the ported artifact.
The mechanism is indifferent to artifact substrate so long as the candidate can be applied to the sandboxed copy of the substrate and exercised against representative evaluation contexts; the disclosure contemplates adaptation artifacts generally, including those distributed to approaching operating units and evaluated through the same sandbox evaluation prior to activation. A pre-certification embodiment contemplates a governance-credentialed certification authority operated independently of the consuming agent: the authority executes the sandbox evaluation and publishes a governed certification observation, and a consuming agent may admit the artifact on the strength of that observation through its composite admissibility evaluator, subject to governance-policy-defined pre-certification-trust parameters, without re-running the evaluation locally. Certification fees may compensate certification authorities for performing sandbox evaluation, where governance policy so provides.
Composition with Adjacent Primitives
The mechanism draws its evaluation contexts from the consuming agent's task context, governance-policy-defined evaluation suites, and the experiential observation store, and records its certification record in the agent's lineage field. The certification record is admissible as input to the composite admissibility evaluator, which other consuming agents apply when considering the same artifact, so the activation-gate outcome operates within the five-property governance chain rather than as an isolated gate.
Composition with the governance summary places licensing constraints, capability-scope boundaries, dependency satisfaction, and authority compatibility into the same evaluation that produces the activation-gate outcome, so an artifact that would breach those constraints is surfaced before activation. Composition with pre-certification lets a certification record produced by a credentialed authority propagate as a governed observation, which a peer agent may admit through its composite admissibility evaluator rather than re-running the evaluation locally. Because the certification record is lineage-recorded, it remains available for post-hoc analysis and regulatory-compliance reporting drawn from the lineage substrate.
Prior-Art Distinctions
A conventional sensor-actuator system applies updates without a governance-credentialed evaluation that is recorded as admissible evidence before activation. The disclosure instead evaluates each adaptation artifact in a sandboxed copy of the consuming agent's substrate before that artifact touches the operational substrate, and binds the outcome into a lineage-recorded certification record rather than leaving the test result unconnected to the activation decision.
The mechanism is distinct because the certification record carries a cryptographic attestation of the sandbox evaluator, is lineage-recorded, and is admissible as input to the composite admissibility evaluations of other consuming agents considering the same artifact. The evaluation contexts are drawn from governance-policy-defined evaluation suites and the consuming agent's own task context and experiential observation store, the activation gate produces an admit-or-reject outcome from the composite of compatibility, performance, governance, and risk assessments, and ambiguous or high-risk outcomes escalate to a deeper second-tier evaluation. These behaviors operate as part of the five-property governance chain imposed on every governed mutation in the architecture.
Disclosure Scope
This article describes subject matter disclosed in U.S. Provisional Application No. 64/049,409. The disclosure covers a sandbox evaluation mechanism by which each adaptation artifact is evaluated in a governance-credentialed sandboxed execution environment prior to activation on a consuming agent's operational cognitive substrate. It encompasses the sandboxed-substrate isolator, the evaluation-context generator, the composition executor, the behavior evaluator, the performance preview generator, the governance summary generator, the risk-projection evaluator, and the activation-gate controller, together with the certification record recorded in the artifact's certification field and the cryptographic attestation of the sandbox evaluator. It encompasses certification records as admissible input to subsequent composite admissibility evaluations at other consuming agents.
Embodiments expressly contemplated include adaptation artifacts applied to a consuming agent's cognitive substrate, firmware updates evaluated in a sandboxed execution environment of the receiving device prior to application, and composite artifacts requiring a fresh certification record and a fresh sandbox evaluation prior to activation. The disclosure extends to pre-certification by a governance-credentialed certification authority that publishes a governed certification observation admissible by any consuming agent, subject to governance-policy-defined pre-certification-trust parameters, and to escalation from a first-tier fast evaluation to a second-tier deeper evaluation with expanded evaluation contexts, longer evaluation duration, and stricter criteria upon ambiguous or high-risk outcomes, governance-policy-configurable per deployment and per adaptation-artifact class.
