Autonomous Remediation and Safe Rollback — Operating Quantum Computers

Automation can stabilize a quantum platform, but unsafe automation can amplify faults. The operational question is not whether to automate. It is what may be automated, under which evidence, with what rollback path, and with whose accountability.

Remediation classes

Class	Example	Autonomy level
informational	annotate target health	automatic
routing	remove target from pool	policy-bounded automatic
workload	pause low-priority jobs	automatic with notification
calibration	trigger diagnostic canary	approval or narrow automation
physical control	alter pulse/control parameters	strict review
claim	freeze public claim	human approval except emergency

Action envelopes

An automated agent should have a machine-readable action envelope.

OPA/Rego-style policy evaluation can authorize structured actions, and TLA+ style models can help validate high-consequence state-machine behavior before implementation. [R177] [R179]

Safe rollback

Rollback is not always undo. In quantum operations, the safer target is return to a validated operating state.

    Stable --> Changed
    Changed --> Verifying
    Verifying --> Stable: checks pass
    Verifying --> Degraded: checks fail
    Degraded --> Rollback
    Rollback --> Stable: validated baseline restored
    Rollback --> ManualIntervention: rollback fails

A rollback plan defines baseline state, affected workloads, owner, communication path, evidence freeze, canary, validation threshold, and final review.

Containment controls

Control	Purpose
rate limits	prevent cascading changes
scoped permissions	prevent cross-domain overreach
cost budgets	prevent runaway execution
feature flags	disable automation quickly
shadow mode	test decisions before action
kill switch	stop automation during incident

Operating rule

Automate reversible, bounded, observable actions first. Every autonomous action needs policy, envelope, verification, rollback, and audit evidence.
