Mechanism
The verification mechanism follows actuation execution. An expected-effect predictor produces, at the time of execution, an expected-effect specification describing the anticipated physical effect of the actuation, including affected state variables, expected magnitudes of state changes, and expected temporal evolution of the effects. A post-actuation-observation consumer then consumes governed observations of the physical system subsequent to execution. These two inputs, the expected-effect specification and the observed effects, are what the mechanism compares.
An effect-comparator compares the observed effects against the expected-effect specification and produces a verification-discrepancy metric. A discrepancy-classifier classifies each verification discrepancy as nominal, as degraded-actuator, as degraded-observation, as environmental-perturbation, as adversarial-interference, or as any governance-policy-defined discrepancy class. The classification names a cause rather than reporting magnitude alone, so that downstream adjustment can respond to the kind of discrepancy and not only its size.
The classification feeds governance-policy-defined downstream effects rather than an immediate control correction. These include adjustment of the confidence thresholds of Section 6.5 for subsequent actuations by the same actuator, adjustment of the actuator's published capability envelope, emission of a governed health-monitoring observation, admission of the discrepancy as input to the integrity conflict resolution mechanism, and emission of a governed calibration-request observation. The downstream effects are governance-policy-configurable, not a fixed remedial catalog selected by the unit.
A verification-lineage recorder records the expected-effect specification, the post-actuation observations, the verification-discrepancy metric, the discrepancy classification, and any downstream adjustments in the lineage field. The original execution record and the verification record form a single governance-chain-recorded transaction that subsequent consumers read as a unit.
Operating Parameters
The confidence thresholds that govern subsequent actuations by the same actuator are adjusted in accordance with verification history. Repeated nominal verifications produce reduced thresholds, and repeated discrepant verifications produce elevated thresholds. The thresholds are governance-policy-defined and propagate through the governance chain rather than being fixed at design time. The disclosure does not specify numeric verification timings or window durations.
Repeated discrepant verifications classified as degraded-actuator reduce the actuator's published capability envelope. In this way the verification mechanism modulates not only the confidence required for the next actuation but the range of actuations the unit is permitted to publish, binding observed actuation reality back to the unit's declared capability.
The expected-effect specification may be produced by a physical-simulation model of the actuator and the physical system. Simulation-based expected-effect prediction is subject to the same track-record maintenance as forecasting kernels, pairing prior expectations with subsequently observed effects so that the simulation model is refined through observed-versus-predicted-effect pairs over time.
Downstream effects are governance-policy-configurable. The same verification outcome may, under one policy, request actuator calibration through a governed calibration-request observation, and under another emit a governed health-monitoring observation or admit the discrepancy to integrity conflict resolution when it indicates inconsistency between the actuation and the observation substrate.
Alternative Embodiments
In a single-unit embodiment, verification operates on local governed observations of the physical system, and the verification record is retained in the lineage field for local forensic use. The verification mechanism does not depend on mesh broadcast to perform the comparison; downstream broadcast of an actuation and its outcome is the subject of a separate actuation-state broadcast mechanism.
The expected-effect specification may be produced either by an expected-effect predictor configured at execution time or by a physical-simulation model of the actuator and the physical system. In the simulation-based embodiment, the prediction is subject to track-record maintenance, so that the model is refined through observed-versus-predicted-effect pairs and earns evidential weight over time in the same manner as a forecasting kernel.
The post-actuation verification mechanism admits simulation-based expected-effect prediction for deployment verification and what-if analysis, where the expected-effect specification is generated by the simulation model before or alongside execution. Across these embodiments the comparison, the verification-discrepancy metric, the classification, and the lineage record are constant; what varies is the source of the expected-effect specification.
The discrepancy-classifier classifies into nominal, degraded-actuator, degraded-observation, environmental-perturbation, adversarial-interference, or any governance-policy-defined class. A governance-policy-defined class lets a domain extend the classification taxonomy through the governance chain, and the disclosed downstream effects respond to the resulting class rather than to discrepancy magnitude alone.
Composition With Other Components
Verification composes with the confidence-threshold mechanism through a feedback edge. Repeated nominal verifications reduce the confidence thresholds required for subsequent actuations by the same actuator, and repeated discrepant verifications elevate them. Repeated discrepant verifications classified as degraded-actuator reduce the actuator's published capability envelope. This feedback connects past actuation reality to future actuation authority.
Verification composes with integrity conflict resolution: when a discrepancy indicates inconsistency between the actuation and the observation substrate, the discrepancy is admitted as input to the integrity conflict resolution mechanism. A discrepancy may also be surfaced through a governed health-monitoring observation upon repeated discrepant verifications, so that the unit's condition is visible to consuming mechanisms.
Verification composes with forensic reconstruction because the verification-lineage recorder writes the expected-effect specification, the post-actuation observations, the verification-discrepancy metric, the discrepancy classification, and any downstream adjustments into the lineage field contemporaneously with the actuation. Reconstructing causality reduces to walking the lineage, since the verification record is bound to the execution record it follows.
Distinction From Prior Art
The disclosure distinguishes the post-actuation verification mechanism from prior feedback-control mechanisms. Prior feedback-control mechanisms produce immediate control corrections without governance-chain recording, without discrepancy classification, and without downstream adjustment of confidence thresholds, capability envelopes, or health-monitoring observations. The verification mechanism disclosed here instead operates at the governance-chain level with authority-credentialed observations.
It produces lineage-recorded verification records, classifying each discrepancy among a governance-policy-defined plurality of classes rather than consuming and discarding the comparison. The verification-discrepancy metric and its classification persist as part of the actuation's lineage, bound to the execution they follow, instead of dissolving into the next control command.
Because the discrepancy is classified by cause, nominal, degraded-actuator, degraded-observation, environmental-perturbation, adversarial-interference, or a governance-policy-defined class, the downstream governance-policy-configurable effects can respond to the kind of discrepancy. This is the structural difference: a classified, recorded, authority-credentialed verification outcome feeds confidence thresholds, capability envelopes, and health-monitoring observations, where a prior feedback loop feeds only the next command.
Failure Modes And Recovery
When the readback fails or degrades, the discrepancy is classified as degraded-observation: the observation substrate that should report the effect is unreliable rather than the actuator being at fault. The classification is recorded in the lineage field, so a discrepancy attributable to the observation path is distinguished from one attributable to the actuator and is available to downstream mechanisms as a distinct input.
When the actuator itself is the source, the discrepancy is classified as degraded-actuator. Repeated discrepant verifications classified as degraded-actuator reduce the actuator's published capability envelope and may trigger a governed calibration-request observation requesting governance-policy-defined actuator calibration. The unit's permitted range of actuation contracts in proportion to its demonstrated reliability.
When a discrepancy indicates inconsistency between the actuation and the observation substrate, it is admitted as input to the integrity conflict resolution mechanism rather than being resolved unilaterally by the verifying unit. The verification mechanism does not select a remedial action from a fixed catalog; its downstream effects are governance-policy-configurable, and an undisclosed timing or recovery behavior is not asserted here.
A discrepancy may be classified as environmental-perturbation, attributing the deviation to a change in the world between prediction and observation, or as adversarial-interference. Each classification, including any governance-policy-defined class, is a lineage entry. Forensic review can later distinguish a unit that operated with consistently nominal verifications from one that accumulated discrepant verifications, because every verification outcome was recorded contemporaneously rather than coerced into a nominal result.
