Confidence-Governed Actuation

Existing functional safety architectures (ISO 26262, IEC 61508) treat actuator commands as binary: permit or suppress. This article introduces confidence-governed actuation: a unified primitive that produces eleven graduated execution modes, a rate-limited preemption budget, reversibility-aware staged commitment, and governance-policy-configurable harm ordering, with mesh broadcast of every actuation state.

Confidence-governed actuation produces eleven categorically distinct modes — simulated, advisory, consultative, shadowed, partial, constrained, stage-gated, deferred, full, emergency-accelerated, emergency-overridden. Mode selection is a deterministic function of composite admissibility against governance policy.

Emergency preemption authority — the ability to override normal admissibility gating — is itself rate-limited under a budget. The budget makes 'emergency' a finite resource rather than an unlimited operational capability.

Actuator commands differ in reversibility. The reversibility classifier evaluates each contemplated commitment against governance-credentialed classification per actuator type per operating context, identifying the commitment-point where reversibility ends.

Stage-gated mode commits irreversible authority in successive bounded stages. Each stage is itself a smaller reversible decision; intermediate admissibility re-evaluation happens at every stage boundary. Aircraft landing flares progressively, surgical procedures advance through clinical stages, defensive engagement decomposes into target classification, weapon arming, and engagement commit.

When all available actuations produce some harm, the actuation that minimizes harm under a governance-policy-configurable entity-class harm ordering is selected. The harm ordering is signed by the governing jurisdiction rather than hardcoded by the manufacturer.

The entity-class harm ordering is itself a credentialed governance policy that the operating jurisdiction signs and updates. Different jurisdictions configure different orderings; cross-jurisdictional operation handles transitions through credentialed cross-recognition.

After an actuator commits, sensed effect is compared to predicted effect. The discrepancy is classified — nominal, expected-noise, anomaly, fault, adversarial-interference — and recorded in lineage with mesh broadcast. The architecture closes the loop between expected and observed actuation.

The discrepancy classifier produces one of five structurally-distinct classifications: nominal, expected-noise, anomaly, fault, adversarial-interference. Each classification has different downstream consumption rules; the architecture supports the operational nuance that uniform-discrepancy treatment cannot.

What a unit is actuating becomes a credentialed observation broadcast through the governed mesh. Neighboring units, infrastructure agents, and regulatory authorities can observe, coordinate, intervene, and audit rather than reconstructing actuation state from telemetry.

Mesh-broadcast actuation state enables cross-unit coordination at structural rather than physical latency. Multiple units operating in shared environments coordinate through credentialed observation flow rather than through reactive observation of each other's effects.

Every actuator commit, every mode selection, every harm-minimization deviation, every post-actuation verification is recorded in lineage with credentialed signatures. Forensic reconstruction of any incident operates structurally rather than through log archaeology.
