AI Agent Governance and Compliance in 2026: Frameworks, Audit Trails, and the Regulatory Reckoning

Executive Summary

The deployment of autonomous AI agents into enterprise production has outpaced the governance frameworks designed to control them. In 2026, two convergent pressures are forcing a reckoning: the EU AI Act's full enforcement activation on August 2, 2026, and the growing evidence that 82% of enterprises already have AI agents or workflows their security teams did not know existed. The result is a governance crisis hiding in plain sight — agents are acting, making consequential decisions, and accessing sensitive systems while organizations are only beginning to build the audit trails, accountability frameworks, and policy enforcement mechanisms that regulators and courts will require.

This research synthesizes the regulatory landscape, technical governance architecture, sector-specific compliance requirements, and practical implementation patterns for governing autonomous AI agents in production. The picture that emerges is not one of compliance theater — it is a genuine engineering problem. Governance for autonomous agents requires instrumentation in the execution path, not just documentation. The organizations getting this right are treating agent governance as an infrastructure discipline alongside reliability and security.

For teams building agent platforms, the key insight is this: an agent's trustworthiness is only as strong as its audit trail. You cannot govern what you cannot observe, and you cannot attribute what you did not log.

The Governance Gap: Why Autonomous Agents Break Traditional Frameworks

Traditional software governance assumes a deterministic system: given input X, the system produces output Y, and a human can review the code to verify this. Autonomous AI agents violate this assumption at every level. Their outputs are probabilistic, their reasoning is opaque, their action sequences emerge from context rather than explicit code paths, and they can delegate to other agents — creating accountability chains no traditional IT governance model anticipated.

Three properties make agents qualitatively harder to govern than conventional software:

Emergent behavior at runtime. An agent's specific actions are not determined at design time — they emerge from the model's reasoning about the current context. This means testing and code review catch only a fraction of the risk surface. An agent that behaves correctly in testing can take unexpected actions when it encounters an edge case in production that its authors never anticipated.

Persistent privileged access. Unlike a user who logs in, performs a task, and logs out, an agent may hold service account credentials, OAuth tokens, and system access indefinitely. Shadow agents — those operating without IT knowledge — often retain high-privilege access long after their original purpose was served, creating a persistent attack surface.

Delegation chains and diffuse accountability. When an orchestrator agent delegates to a sub-agent which calls an API which modifies a database, the accountability chain spans multiple layers. Traditional security models — based on who authenticated — break down when agents authenticate on behalf of users who may not know the specific actions being taken.

Gartner projects that 40% of enterprise applications will feature task-specific AI agents by end of 2026, up from under 5% in 2025. The governance gap between agent deployment velocity and control maturity is widening faster than most organizations recognize.

Regulatory Landscape: EU AI Act and Beyond

Full Enforcement: August 2, 2026

The EU AI Act entered into force on August 1, 2024. Its August 2, 2026 date is not a compliance deadline — it is when the European Commission gains enforcement powers and can impose fines. Organizations that have not built compliant systems by then face penalties up to €35 million or 7% of global annual revenue, whichever is larger.

The Act's application to autonomous AI agents depends on application domain, not technical architecture. An agent used for recruiting decisions, credit assessment, critical infrastructure management, or clinical decision support triggers the high-risk AI system classification under Annex III — regardless of whether it uses the same underlying model as a low-risk customer service chatbot.

High-risk AI system obligations (directly applicable to agents):

Technical documentation covering decision logic, model architecture, and training procedures
Conformity assessments before deployment
Risk management procedures maintained throughout the system lifecycle
Human oversight mechanisms with explicit documented intervention points
Automatic log generation retained for minimum 6 months (Article 19), longer if sector rules require
Registration in the EU's forthcoming public AI database

The deployer accountability trap. Most enterprise AI agent teams are not AI model providers (who trained the model) — they are deployers (who apply a third-party model to a specific use case). The EU AI Act assigns significant obligations to deployers even when they didn't build the underlying AI. A company using Claude or GPT-4o to power an autonomous HR agent is the deployer and carries compliance burden for how that agent is configured, deployed, and monitored.

GPAI obligations. Agents built on general-purpose AI models (trained with >10²³ FLOPs) must navigate GPAI provider requirements: technical documentation, downstream provider support, and copyright compliance. Models exceeding 10²⁵ FLOPs training compute are presumed to have systemic risk and face additional obligations including adversarial testing, incident reporting to the AI Office, and cybersecurity measures.

Compliance architecture checklist for EU-facing agent deployments:

Document the agent's decision logic and tool invocation patterns
Assess whether the application domain triggers high-risk classification
Implement human oversight with defined escalation thresholds
Enable stop/correction controls that a human can invoke in real time
Establish 6-month log retention with tamper-evident storage
Map GPAI obligations if the underlying model qualifies

California AI Act (June 2026)

California's AI Act of 2026 adds jurisdiction-specific disclosure and governance requirements for high-risk AI systems serving California residents. Organizations building US-based agent platforms face a patchwork of state-level requirements alongside federal agency guidance — FINRA, SEC, FDA, and FTC have all issued AI-specific guidance with direct bearing on autonomous agents.

NIST AI RMF and ISO/IEC 42001: Operational Governance Frameworks

NIST AI RMF: Filling the Agentic Gap

NIST AI RMF 1.0 (released January 2023) provides the four-function GOVERN–MAP–MEASURE–MANAGE model for AI risk management. But it was designed before autonomous agents were production-grade. NIST acknowledged this gap in February 2026 with its AI Agent Standards Initiative through the Center for AI Standards and Innovation (CAISI), with an AI Agent Interoperability Profile planned for Q4 2026.

In the interim, practitioners have extended the RMF with agentic-specific controls:

GOVERN function extensions:

Establish Agentic AI Committees alongside traditional AI ethics boards, with authority to approve agent deployment and scope changes
Define agent-specific risk tolerance thresholds — what types of external actions, data access, and delegation are acceptable without human approval
Maintain an Agent Registry: every production agent documented with its purpose, authority scope, owning team, and review schedule

MAP function extensions:

Document every agent's complete authority surface: what tools it can invoke, what data it can access, what external systems it can affect
Map delegation chains — if Agent A can spawn Agent B, both must be documented and their combined authority surface assessed
Identify failure modes: what happens if the agent loops, takes unexpected actions, or encounters adversarial input?

MEASURE function extensions:

Monitor decision accuracy (spot-checked by domain experts), goal drift (is the agent pursuing its intended objective?), and unexpected tool invocation rates
Track cost-per-task trends — dramatic cost increases often signal agents entering inefficient loops
Measure human oversight utilization — are escalation mechanisms actually being used, or are they theoretical?

MANAGE function extensions:

Implement circuit breakers that terminate agents exceeding failure thresholds
Maintain rollback procedures — how do you undo an agent's recent actions?
Define agent quarantine: isolating a misbehaving agent without disrupting dependent systems

ISO/IEC 42001: The Enterprise Standard

ISO/IEC 42001 (published December 2023) is the world's first AI Management System standard, modeled on the ISO 9001/27001 framework familiar to enterprise compliance teams. In 2026, major cloud providers including AWS, Microsoft, and SAP have achieved certification. Increasingly, enterprise procurement teams require ISO 42001 certification from AI vendors as a condition of purchase — the certification is becoming a market differentiator for AI platforms.

The standard's most relevant controls for autonomous agent deployments:

AI impact assessment: Document what happens when an agent makes mistakes, including downstream effects and recovery procedures
Responsibility assignment: Every AI system must have a documented owner responsible for its behavior and outcomes
Lifecycle management: Agents must be regularly reviewed, updated, and decommissioned when no longer appropriate
Continual improvement: Governance programs must demonstrate learning from incidents and near-misses

Five control domains that satisfy both NIST AI RMF and ISO 42001 for most agent deployments: policy articulation, access controls, observability, incident response, and bias/drift monitoring.

Audit Trail Architecture for Agent Systems

The Regulatory Floor

EU AI Act Article 19 mandates 6-month automatic log retention for high-risk systems. Financial services regulators (FINRA, SEC) require up to 7 years for audit trails related to trading and advice. HIPAA requires retention of audit logs for healthcare AI for 6 years. GDPR's accountability principle means organizations must be able to demonstrate they processed personal data lawfully — including data processed by agents on users' behalf.

These requirements set the floor. Production-grade agent audit infrastructure should exceed them.

What to Log: The Agent Decision Record

An Agent Decision Record (ADR) is the emerging standard for compliance-ready agent audit entries. Unlike application logs optimized for debugging, ADRs are designed to answer regulatory and legal questions post-hoc:

{
  "adr_id": "unique-immutable-id",
  "timestamp": "2026-05-01T14:23:45.123Z",
  "session_id": "session-reference",
  "agent_id": "agent-instance-identifier",
  "principal": {
    "user_id": "delegating-user",
    "scope": ["read:calendar", "write:email"],
    "authority_expiry": "2026-05-01T18:00:00Z"
  },
  "trigger": {
    "type": "scheduled_task | user_request | agent_delegation",
    "input_summary": "...",
    "policy_version": "v2.3.1"
  },
  "context_snapshot": {
    "tools_available": [...],
    "data_sources_accessed": [...],
    "prior_steps": [...]
  },
  "reasoning_trace": [...],
  "tool_invocations": [
    {
      "tool": "send_email",
      "parameters": {...},
      "authorization_check": "passed",
      "result": "success",
      "timestamp": "..."
    }
  ],
  "human_oversight_events": [...],
  "outcome": {
    "actions_taken": [...],
    "external_effects": [...],
    "reversibility": "reversible | irreversible"
  },
  "integrity_hash": "sha256:..."
}

The ADR answers: who authorized this, what context did the agent have, what did it decide to do, was that consistent with policy, and what were the real-world effects?

Data Volume and Infrastructure

A single agent interaction generates 5–50KB of audit data. At 10,000 daily interactions, this is 36–182GB annually. This requires dedicated audit infrastructure:

Active tier (12–24 months): Queryable audit database, indexed by agent ID, user ID, session, and action type
Archival tier (3–7 years): Compressed, immutable, air-gapped from operational systems, cryptographically signed
SIEM integration: Real-time streaming to security information management systems for anomaly detection

MCP as an Audit Chokepoint

With the Model Context Protocol becoming the dominant interface for AI agent tool access, MCP gateways are natural audit chokepoints. Every tool invocation passes through the MCP layer — making it the right place to enforce logging, authorization, and rate limiting.

A five-layer MCP audit framework covers:

Authentication/authorization: Every MCP request authenticated to a principal with documented scope
Provenance tracking: Trace context propagated through every tool call, enabling end-to-end request tracing across multi-agent workflows
Isolation/sandboxing: Tool calls executed with minimum necessary permissions
Inline policy enforcement: Policy checks in the request path, not after the fact
Centralized governance dashboard: Aggregated view across all agents and tool invocations

The current gap: MCP lacks standardized audit logging in its protocol specification. Organizations building production agent platforms must implement audit logging at the MCP gateway layer themselves — there is no built-in mechanism.

Immutability Requirements

Regulatory-grade audit trails must be tamper-evident:

Write-once storage: No UPDATE or DELETE operations on audit records
Cryptographic batch signatures: Each log batch signed and the signature stored independently
Periodic integrity verification: Automated checks that log records match their stored hashes
Separation of duties: Audit infrastructure administered independently from the operational systems it monitors

Accountability in Multi-Agent Systems

The hardest governance question of 2026 is attribution: who is responsible when a chain of agents causes harm?

Legal analysis from Venable LLP, Squire Patton Boggs, and Davis Wright Tremaine reaches consistent conclusions: autonomy redistributes but does not eliminate accountability, with responsibility ultimately resting with the humans who design, deploy, authorize, or benefit from AI systems. But in multi-agent architectures spanning dozens of intermediate decisions, reconstructing that chain post-hoc is technically difficult and legally uncertain.

The core problem: Agent-generated actions outpace human verification capacity by orders of magnitude. When Agent A delegates to Agent B which calls Agent C to modify a production database, the full delegation chain must be reconstructable after the fact. Most current observability tooling does not capture inter-agent communications with sufficient granularity for regulatory-grade attribution.

Principles for governable delegation:

Identity binds authority: Every agent must document its principal hierarchy — who authorized it, with what scope, for how long. Without this, accountability fragments under compositional autonomy.
Authority must be scoped and time-bounded: Agents should not hold persistent broad permissions. Service account tokens should expire and require re-authorization. This limits blast radius when agents are compromised or misbehave.
Every delegation must be logged: When an agent spawns or delegates to another agent, that delegation — including the scope of authority transferred — must be recorded in the audit trail.
Accountability anchored before action: Governance controls must be in-path (checked before the action executes), not forensic-only (reconstructed after failure). Forensic governance catches problems after damage is done; path governance prevents them.

Singapore's MAS guidelines (increasingly adopted as a global benchmark) operationalize these principles: assess and bound new agent risks before deployment; increase human accountability for agent oversight; implement technical controls limiting agent authority; enable end-users to understand and manage risks.

The "responsibility vacuum" problem: The Galileo AI research (December 2025) on multi-agent failures found that in simulated systems, a single compromised agent poisoned 87% of downstream decision-making within 4 hours — faster than traditional incident response could contain. This "cascade failure" pattern means that in densely connected multi-agent systems, individual agent governance is insufficient. System-level circuit breakers and quarantine mechanisms are required.

Enterprise Governance Structures

The CAIO Surge

In 2026, 76% of surveyed organizations report a Chief AI Officer (IBM Institute for Business Value), up from 26% in 2025. CAIO job postings are up 340% since 2023. Among FTSE 100 companies, nearly 48% have a CAIO or equivalent role.

The business case is clear: organizations with dedicated AI leadership achieve 44% success rate moving GenAI prototypes to production (vs 36% without), and 28% report direct AI-attributable revenue growth (vs 13% without). Centralized AI governance models yield 36% higher ROI than decentralized approaches.

The CAIO role in 2026 is increasingly focused on agentic AI governance — specifically: maintaining the agent registry, setting delegation authority policies, chairing the Agentic AI Committee that approves new agent deployments, and owning the incident response process when agents cause harm.

Shadow AI: The Ungoverned Agent Crisis

82% of organizations discovered at least one AI agent or workflow their security teams did not previously know about. Only 13% believe they have adequate governance in place. 98% report some form of unsanctioned AI use.

Shadow agents are qualitatively more dangerous than shadow applications. They operate at machine speed, can persist system access indefinitely, and can autonomously initiate sequences of privileged actions without human review. Real-world consequences: a healthcare company was fined $3.5M for feeding patient notes into ChatGPT in HIPAA violation; a manufacturer lost $54M after a coding assistant leaked proprietary data.

Shadow agent detection requires:

Network monitoring: Identify traffic to AI API endpoints (OpenAI, Anthropic, Google, Cohere)
DLP rules: Catch LLM-formatted request/response patterns leaving the corporate network
Application inventory: Scan for installed agent frameworks (LangChain, AutoGen, CrewAI, Claude Code)
Service account audits: Identify service accounts created without IT involvement that are making AI API calls

Governance Tooling Landscape

A governance tooling market is consolidating around five capability categories:

Agent observability: Helicone, LangSmith, Arize, Phoenix — capturing agent traces and reasoning
Agent security: Zenity, Protect AI, Lakera — runtime monitoring and prompt injection detection
Policy enforcement: OPA (Open Policy Agent) deployments for agent authorization
Compliance reporting: Platforms generating compliance documentation from agent operational data
AI audit: Specialized audit trail management with regulatory retention and tamper-evidence

Policy Enforcement Patterns

Production agent governance requires policy enforcement in the execution path. The emerging architecture is the Agent Control Plane — a governance layer sitting between the agent runtime and the tools/data sources it uses.

Tool allowlisting: Every agent has an explicit, version-controlled allowlist of approved tools. Attempts to invoke unapproved tools are blocked and generate audit alerts. Parameters are validated against schemas that include authorization context.

Circuit breakers: Three-state machines (closed → open → half-open) that terminate agent execution when failure thresholds are exceeded:

Closed: Normal operation
Open: Failure threshold exceeded; requests fail fast rather than accumulating damage
Half-open: Testing recovery with limited requests

Triggers include: repeated tool failures, downstream API throttling, anomalous output patterns, excessive resource consumption, or unusual data access volumes.

Read-to-write escalation: The critical heuristic — require human approval when an agent's plan shifts from reading information to modifying external systems. Reading is inherently lower risk than writing; the transition from read to write is the natural escalation point.

Safe mode degradation: When circuit breakers trip, agents degrade to read-only tool access rather than complete shutdown. The agent can still gather information, assess the situation, and escalate to a human — it simply cannot take further external actions.

Policy-as-code: Agent policies expressed as versioned, machine-readable configurations (OPA rules, JSON policy documents) rather than prose. Benefits: policies can be tested against sample decisions, diffed in PRs, and enforced programmatically. Version control of policies provides the audit trail that governance teams need.

Approval flow architecture: High-stakes actions generate approval requests containing: the proposed action and parameters, the agent's reasoning trace, the estimated impact and any side effects, rollback procedure if available, and expiry time (approval requests should not be valid indefinitely).

Sector-Specific Compliance

Financial Services

FINRA's 2026 Regulatory Oversight Report specifically addresses autonomous agents, flagging three novel risks: autonomy (agents acting without human validation), scope creep (agents exceeding their intended authority), and auditability (multi-step reasoning making decisions hard to trace). FINRA's requirements for broker-dealer AI agents:

Supervisory processes specific to each agent's type and scope
Monitoring of agent system access and data handling patterns
Defined "human in the loop" protocols — when does an agent require human approval before acting?
Guardrails limiting agent behaviors, with documented override procedures

FINRA's technologically-neutral rules mean existing securities obligations — suitability, best execution, supervision — apply to AI agents as they do to human advisors. An agent providing investment recommendations must satisfy the same suitability analysis requirements as a human broker. An agent executing trades must meet best execution standards.

The specific risk called out: models trained on historical market data can produce unreliable outputs during crises — pandemics, geopolitical shocks, extreme volatility — that fall outside training distributions. Supervisory systems must detect when agents are operating outside their reliability envelope.

Healthcare

FDA's January 2026 guidance introduced a significant relaxation: CDS software that provides a single clinically appropriate recommendation while enabling clinicians to independently review the basis may qualify for enforcement discretion — avoiding the premarket approval process that applies to regulated devices. The key test: can a clinician independently review and verify the AI's reasoning? Software designed for time-sensitive critical decisions where clinicians lack time for independent review remains regulated.

The January 2026 guidance increases emphasis on transparency: AI-driven CDS must document its data inputs, underlying logic, and recommendation generation process. This transparency requirement is the FDA's operational definition of meaningful human oversight.

HIPAA requirements for AI agents: any agent accessing protected health information must be covered by Business Associate Agreements. All PHI access must be logged. Data breach notifications filed within 60 days of discovery (US); GDPR's 72-hour window applies for EU patient data.

Legal Sector

AI agents conducting legal research, drafting contracts, or providing legal analysis face unauthorized practice of law concerns. No major jurisdiction has definitively resolved whether an AI agent "practicing law" triggers UPL statutes. The safe harbor in 2026: frame AI legal tools as research assistance requiring attorney review and sign-off — document clearly that the AI is not the practicing attorney.

Incident Response for AI Agents

When an autonomous agent causes harm, the incident response lifecycle differs from traditional software incidents in three ways: the scope of impact may be unknown (the agent may have taken many actions across many systems), forensics require replaying the agent's decision trace (not just reading error logs), and regulatory notification timelines may be triggered by the agent's data access patterns.

Incident Response Playbook for AI Agents:

1. Detection

Anomaly detection on agent output volume, error rates, external API call rates, and data access patterns
Circuit breaker activation as a detection signal (circuit breakers tripping often indicate an active incident)
User reports of unexpected agent behavior

2. Containment

Activate circuit breakers for affected agent
Terminate active agent sessions
Rotate credentials for service accounts the agent held
Block agent's network access if compromise is suspected

3. Scope Assessment

Replay audit logs to enumerate: which actions were taken, what data was accessed, what external effects occurred, which users were affected
This step requires complete, queryable audit logs — retrospective reconstruction without logs is often impossible

4. Regulatory Notification

GDPR 72-hour clock starts when a personal data breach is discovered — not when it occurred
FINRA/SEC notification requirements if trading or investment systems were affected
HIPAA 60-day notification if PHI was involved
Internal incident management and escalation procedures

5. Forensics

Reconstruct the full decision chain from ADRs
Identify where governance controls failed — was it a policy gap, a logging gap, a circuit breaker that wasn't configured?
Preserve evidence with chain-of-custody controls for potential litigation

6. Post-Mortem and Policy Update

Update agent policy configurations based on findings
Update monitoring rules to detect similar failures earlier
Review agent authority scopes — were they minimally privileged?
Share lessons with governance committees

Prompt Injection as a Compliance Risk

In regulated environments, prompt injection is not merely a security concern — it is a compliance event. When injected instructions cause an agent to access data outside its authorized scope, that unauthorized access may trigger GDPR notification obligations, HIPAA breach reporting, or SOX audit violations regardless of human intent.

Prompt injection appeared in 73% of production AI deployments studied in 2025. The compliance-specific implication: model-level defenses (instruction hierarchy, system prompt hardening) are necessary but insufficient. Defense-in-depth requires:

Data-layer access controls: The model can only retrieve data the authenticated user is authorized to see — injected instructions cannot escalate data access beyond the user's permissions
Application-layer input validation: Sanitize and validate inputs before they reach the agent context
Human approval gates: High-risk actions (financial transactions, data export, code deployment) require human approval regardless of what instruction the agent received
Output monitoring: Flag agent outputs that match patterns associated with data exfiltration or privilege escalation

Only access controls enforced at the data layer, independent of the model, can prevent an injected instruction from producing a compliance event. This is the architectural constraint that drives the "least-privilege agent" design pattern — agents should have access to only the specific data and tools needed for their current task, not persistent broad access.

Implications for Zylos and Similar Systems

For a personal/team AI agent platform like Zylos — with system access, credential handling, multi-channel communication, and autonomous task execution — the governance practices with the highest priority are:

1. Implement an Agent Registry. Every component that takes autonomous action should be documented: its purpose, authority scope (what tools, what data, what channels), owning context, and review schedule. Zylos's skills architecture is well-suited for this — each skill can carry a governance manifest documenting its authority surface.

2. Audit every consequential action. The memory system, scheduler, communication bridge, and HTTP server all take actions with real-world effects. Log every non-trivial action with: the triggering event, the agent state at the time, the action taken, and the outcome. This is particularly important for actions that are irreversible (sending messages, modifying files, making external API calls).

3. Implement read-to-write escalation for high-stakes operations. Before executing an action that cannot be easily undone — sending a message to a group, modifying production data, making an external API call — consider whether the action warrants a confirmation step. For fully autonomous scheduled tasks, this means defining a "safe" set of actions that can be executed without escalation, and a "review required" set that surfaces to the owner before execution.

4. Scope service account permissions minimally. Each component should hold only the permissions it needs for its specific function. The scheduler doesn't need the same permissions as the communication bridge. Compartmentalization limits blast radius when a component misbehaves or is compromised.

5. Build circuit breakers into long-running autonomous tasks. Scheduled tasks that fail repeatedly should not continue retrying indefinitely. Implement failure thresholds that pause execution and surface an alert, rather than allowing an agent to loop in a failure state.

6. Apply prompt injection defenses for multi-channel inputs. Messages arriving from external channels (Telegram, Lark, WeChat) are untrusted inputs. Treating them as such — with appropriate validation, scope constraints, and privilege separation between channel inputs and system authority — is the correct security posture.

7. Document the owner's authority delegation clearly. Zylos's security model is built around a verified owner identity. Make this delegation explicit: what can Zylos do autonomously? What requires owner confirmation? What requires explicit per-action approval? Documenting these thresholds is both a governance practice and a safety measure.

Key Takeaways

August 2, 2026 is enforcement day for the EU AI Act. Organizations with agents in high-risk application domains in the EU must have conformity assessments, human oversight mechanisms, and 6-month log retention in place — not in planning.
76% of enterprises now have a CAIO, but only 13% believe they have adequate AI governance. Governance structures are not keeping pace with agent deployment velocity.
82% of enterprises discovered unknown AI agents on their networks. Shadow AI agents operating with persistent privileged access are the most dangerous unaddressed enterprise risk in 2026.
Audit trails for agents must answer four questions: Who authorized this? What context did the agent have? What did it decide? Was that consistent with policy? If your logging cannot answer these, you are not audit-ready.
Prompt injection in regulated industries is a compliance event, not just a security incident. Data-layer access controls — independent of the model — are the only reliable defense.
Multi-agent accountability requires pre-action governance, not post-hoc forensics. Every agent-to-agent delegation must be logged with authority scope. Attribution chains that are not instrumented in real-time cannot be reliably reconstructed after the fact.
The Agent Control Plane is becoming infrastructure. Organizations serious about agent governance are building dedicated policy enforcement, audit, and circuit breaker layers between agent runtimes and the systems they interact with — treating agent governance as a first-class infrastructure discipline alongside observability and security.
