Mechanism
An actuation-state observation constructor produces a governed actuation-state observation for each executed actuation. The observation is the same governed observation primitive used elsewhere in the architecture, here characterizing the actuation the unit just performed. It comprises, at minimum, the issuing governed unit's authority credential, a dynamic device hash, a spatial reference identifying where the actuation occurred, a temporal reference identifying when it occurred, an actuator-identifier field, an actuation-type field, an actuation-parameter field, a selected-mode field identifying the graduated-actuation mode selected for execution, a composite-admissibility-determination field recording the determination input to that mode selection, an expected-effect field, a time-to-live field, and a cryptographic integrity attestation.
An actuation-state observation emitter propagates the governed actuation-state observation through the mesh. The emission is per executed actuation: the actuation-state broadcast step is the stage of the actuation chain that, following actuator execution and post-actuation verification, emits the governed actuation-state observation to the mesh, after which the executed actuation, observed effects, verification outcome, and broadcast event are recorded in the unit's lineage field.
An actuation-state consumer interface at receiving devices accepts governed actuation-state observations through the composite admissibility evaluator. Only admitted observations are consumed; the consuming device incorporates admitted actuation-state observations into its experiential observation store and cognitive primitives. Admissibility is evaluated by the same composite admissibility evaluator that governs the device's other governed observations, so an actuation-state observation that fails admissibility at a receiving device is not consumed there.
The cryptographic integrity attestation carries a signature over the preceding fields of the observation. The issuing unit's authority credential binds the observation to the unit's governance-chain identity, and the dynamic device hash binds it to the emitting device. These elements are the load-bearing integrity structure of the observation as it propagates through the mesh; the architecture does not depend on a trusted third party to vouch for an observation, because the credential and attestation travel with the observation itself.
Observation Fields
The selected-mode field identifies the graduated-actuation mode selected for execution. Because the same unit can execute an actuation in any of its graduated modes, the broadcast records which mode was actually committed, so a consuming device learns not only that an actuation occurred but the degree of authority under which it was executed.
The composite-admissibility-determination field records the admissibility determination that was input to the mode selection. This binds the observation to the governance reasoning behind the actuation rather than reporting the actuation in isolation, so a consuming device can relate the actuation to the admissibility determination that authorized it.
The expected-effect field encodes the expected-effect specification associated with the actuation. The same expected-effect specification is the reference against which the unit's post-actuation verification mechanism compares observed effects, so the broadcast carries the unit's own statement of what the actuation was intended to accomplish.
The actuator-identifier, actuation-type, and actuation-parameter fields identify the specific actuator engaged, the category of actuation, and the parameters of the actuation. Together with the spatial reference, the temporal reference, and the time-to-live field, they let a consuming device locate the actuation in space and time and bound the interval over which the observation remains current.
Alternative Embodiments
In one embodiment, neighboring units adjust their own planning graphs in accordance with observed actuations of the broadcasting unit. A first vehicle observing a second vehicle's broadcast emergency-braking actuation adjusts its own following distance accordingly. The coordination here is direct: the consuming unit acts on the actuation it observes rather than inferring the other unit's behavior indirectly.
In another embodiment, cognitive infrastructure agents aggregate actuation-state observations into dispositional fields, producing locations of elevated actuation frequency or elevated actuation-mode constraint. The aggregated actuation-state observations across many units become a spatial signal that an infrastructure agent can publish back into the mesh.
In a further embodiment, forecasting agents consume actuation-state observations as inputs to fleet-behavior forecasting and cascade-propagation forecasting. The observations serve as a behavioral signal from which forward-looking estimates of fleet behavior and of how disturbances may propagate are derived.
In an embodiment directed to per-unit assessment, health-monitoring agents consume actuation-state observations for per-unit operational-health assessment, and reputation-track-record agents consume the same observations for per-unit reputation maintenance. The same broadcast observation thus supports both a health view and a track-record view of the emitting unit.
In a further embodiment, any governance-credentialed agent consumes actuation-state observations in accordance with the agent's governance-policy-defined consumption authority. The set of consumers is not fixed: an agent may consume actuation-state observations to the extent its governance policy authorizes such consumption.
Composition
The actuation-state observation composes with the actuation chain by occupying a defined step within it. Following actuator execution and post-actuation verification, the actuation-state broadcast step emits the governed actuation-state observation to the mesh, and a subsequent post-execution lineage-recording step records the executed actuation, the observed effects, the verification outcome, and the broadcast event in the unit's lineage field. The broadcast is thus one stage of the unit's own governance loop, not a separate reporting subsystem.
The actuation-state observation composes with the lineage substrate through that post-execution lineage recording. Because the broadcast event is itself recorded in the lineage field alongside the executed actuation and its verification outcome, the unit's lineage retains a record that the actuation-state observation was emitted, preserving governance-chain provenance across the broadcast step.
The actuation-state observation composes with cohort-level aggregation through cognitive infrastructure agents. Such agents aggregate actuation-state observations into dispositional fields, producing locations of elevated actuation frequency or elevated actuation-mode constraint. The aggregate of how a cohort is exercising its actuators thereby becomes a dispositional signal grounded in actual broadcast observations rather than in inferred external conditions.
The actuation-state observation composes with governance-credentialed consumption generally. Any governance-credentialed agent consumes actuation-state observations in accordance with its governance-policy-defined consumption authority, so the same broadcast observation can support forecasting, health monitoring, reputation maintenance, and other consumers without per-vendor integration, each consumer admitting the observation through its own composite admissibility evaluator.
Prior-Art Distinctions
The actuation-state broadcast mechanism is structurally distinguished from prior closed-loop control-system architectures. In a prior closed-loop control architecture, actuation state is confined to the internal feedback loop of the controlling system. The present mechanism instead propagates the actuation state to the external mesh as a governance-credentialed observation rather than confining it to the executing system.
This structural difference is what enables the cross-unit coordination mechanisms the broadcast supports. Because the actuation state leaves the executing system as a governed observation that other governance-credentialed units and agents can admit and consume, neighboring units, infrastructure agents, forecasting agents, health-monitoring agents, reputation agents, and other authorized consumers can act on the actuation, which a system that confines actuation state to its own feedback loop cannot make available.
Disclosure Scope
The disclosed subject matter encompasses an actuation-state broadcast mechanism in which every governed actuation executed by a governed unit is emitted as a governed actuation-state observation propagated through the governed mesh, the mechanism comprising an actuation-state observation constructor producing a governed actuation-state observation for each executed actuation, an actuation-state observation emitter propagating the observation through the mesh, and an actuation-state consumer interface at receiving devices accepting the observation through the composite admissibility evaluator and consuming admitted observations into the receiving device's experiential observation store and cognitive primitives. The governed actuation-state observation comprises, at minimum, the issuing unit's authority credential, a dynamic device hash, spatial and temporal references, actuator-identifier, actuation-type, and actuation-parameter fields, a selected-mode field, a composite-admissibility-determination field, an expected-effect field, a time-to-live field, and a cryptographic integrity attestation. The disclosed scope is not limited to any particular actuator domain, whether vehicular, industrial, infrastructural, or otherwise, and includes the cross-unit coordination mechanisms enabled by the broadcast, including planning-graph adjustment by neighboring units, aggregation into dispositional fields by cognitive infrastructure agents, consumption by forecasting agents, health-monitoring agents, and reputation-track-record agents, and consumption by any governance-credentialed agent in accordance with its governance-policy-defined consumption authority.
