AI Agents: From Pilot to Production in 2026

The enterprise AI landscape has shifted dramatically. Mid-2026 marks the inflection point where organizations move beyond conversational chatbots to deploy action-oriented, governance-compliant agentic workflows at scale.

⚡ TL;DR — The 2026 Enterprise Agent Reality

  • 🚀 Pilots are Over: Enterprises now demand action-oriented agents that execute workflows, not just retrieve information (RAG → Action).
  • 🔗 Agentic iPaaS is Rising: The fusion of RPA and AI agents creates a new integration paradigm — agents that can operate both modern APIs and legacy UIs via Vision-Language Models (VLMs).
  • 🔐 Dual-Token Governance: Production agents require both system-level credentials and end-user OAuth tokens to prevent privilege escalation.
  • 📊 Proven ROI: Tier-1 IT support automation yields $3.40 return per dollar, with cost-per-ticket dropping from $22 to $1.40.

1. From RAG to Action: The Paradigm Shift

In 2025, the dominant pattern was RAG (Retrieval-Augmented Generation): agents could read enterprise data and answer questions. In 2026, the expectation has shifted to Action-Oriented Agents — systems that don't just retrieve, but execute: resetting passwords, provisioning licenses, updating CRM records, and deploying code.

This shift introduces a fundamentally different risk profile. A read-only agent that hallucinates produces a wrong answer; an action-oriented agent that hallucinates can delete a database, approve a fraudulent transaction, or deploy broken code to production.

Dimension 2025 Pilot (RAG-Based) 2026 Production (Action-Oriented)
Primary Function Information retrieval & summarization Autonomous task execution & workflow automation
System Access Read-only (vector DB, document store) Read/Write (APIs, databases, UI automation)
Failure Mode Wrong answer (low impact) Wrong action (high impact — data loss, compliance breach)
Governance Optional content filtering Mandatory HITL, RBAC, immutable audit trails

2. Bridging Legacy Systems: The "Agentic iPaaS" Architecture

The most common blocker for enterprise agent deployment isn't the LLM — it's the legacy system landscape. Monolithic ERPs, mainframe terminals, and internal tools built in the 2000s lack modern APIs. Simply saying "agents need APIs" is insufficient. The 2026 solution is a two-pronged integration architecture:

⬆️ Top-Down: Semantic Gateway

For systems that do have REST/SOAP APIs, enterprises deploy a Semantic Layer that translates raw API endpoints into LLM-friendly OpenAPI Tool Specifications. The agent doesn't call POST /api/v2/users/{id}/password directly — it calls a semantic tool named reset_user_password with typed parameters, auto-validated by the gateway.

Tools: Hasura DDN, Apollo GraphQL Federation, custom OpenAPI-to-ToolSpec wrappers

⬇️ Bottom-Up: Generative RPA (UI-Agent)

For systems with no API at all (legacy mainframes, desktop ERP clients), a new class of Vision-Language Model (VLM) agents can directly interact with the UI. These "UI-Agents" take screenshots, understand the interface visually, and execute click/type actions — essentially a Generative RPA layer powered by models like GPT-4o or Gemini's multimodal capabilities.

Tools: Anthropic Computer Use, Microsoft UFO, UiPath Autopilot with VLM

3. Governance & Security: Engineering Trust

The #1 concern from enterprise CISOs and CTOs is: "What prevents the agent from doing something catastrophic?" The answer is a layered security architecture with three non-negotiable components:

🔐 Dual-Token Authentication

Every agent action must carry two credentials simultaneously:

  • Agent System Token: Identifies which agent is performing the action (bound to specific permissions and rate limits).
  • User OAuth Token: Identifies which human initiated the task. The agent inherits the user's permission scope — it can never escalate beyond what the triggering user is authorized to do.

This prevents Privilege Escalation — even if the agent's system token has broad API access, the action is bounded by the human's role.

📜 Immutable Audit Trails

All agent activity — including the full Chain-of-Thought (CoT), tool call parameters, and execution results — must be written to a write-once, read-many (WORM) audit log in real time. This is not optional for regulated industries (finance, healthcare, government).

  • What to log: Agent ID, User ID, timestamp, reasoning trace, tool name, input parameters, output, latency.
  • Where to log: AWS CloudTrail, Azure Immutable Blob, or specialized AI audit platforms like Patronus AI.

⛔ Human-in-the-Loop (HITL) Interrupt Gates

Critical actions (financial transactions > $5K, production deployments, PII data exports) must trigger a hard interrupt. The agent pauses execution, sends an approval request (via Slack, email, or an internal dashboard), and resumes only after explicit human authorization. In LangGraph, this is implemented natively via interrupt() at the node level.

4. Case Study: IT Support — From Chatbot to Agentic Workflow

In Q1 2026, a Fortune 500 financial services company transitioned their IT Helpdesk from a GPT-powered chatbot (which could only answer questions about IT policies) to a full agentic workflow that autonomously executes Tier-1 support tasks: password resets, software license provisioning, VPN certificate renewal, and intelligent escalation routing.

The implementation uses LangGraph with the latest Command API for state updates, interrupt() for HITL approval on sensitive operations, and structured tool calling with audit logging.

from typing_extensions import TypedDict
from langgraph.graph import StateGraph, START, END
from langgraph.types import Command, interrupt

audit_log = logging.getLogger("agent.audit")

class TicketState(TypedDict):
    ticket_id: str
    user_email: str
    issue_type: str        # classified by the agent
    action_result: str
    requires_approval: bool
    audit_trail: list[str]

def classify_ticket(state: TicketState) -> Command[Literal["execute_action", "escalate"]]:

    # In production: call LLM with structured output
    issue = "password_reset"  # simplified
    audit_log.info(f"[{state['ticket_id']}] Classified as: {issue}")

    if issue in ("password_reset", "license_provision", "vpn_renewal"):
        return Command(
            update={"issue_type": issue, "audit_trail": [f"Classified: {issue}"]},
            goto="execute_action"
        )
    return Command(
        update={"issue_type": "complex", "audit_trail": [f"Classified: {issue} → escalate"]},
        goto="escalate"
    )

def execute_action(state: TicketState) -> Command[Literal["hitl_approval", END]]:
    """Execute the Tier-1 action via enterprise tool APIs."""
    if state["issue_type"] == "password_reset":
        # Dual-token auth: agent_token + user_oauth_token
        result = "Password reset link sent to user"
        needs_approval = False
    elif state["issue_type"] == "license_provision":
        result = "License provisioned (pending approval)"
        needs_approval = True  # costs money → requires HITL
    else:
        result = "VPN certificate renewed"
        needs_approval = False

    trail = state["audit_trail"] + [f"Action: {result}"]
    audit_log.info(f"[{state['ticket_id']}] {result}")

    if needs_approval:
        return Command(
            update={"action_result": result, "requires_approval": True, "audit_trail": trail},
            goto="hitl_approval"
        )
    return Command(
        update={"action_result": result, "requires_approval": False, "audit_trail": trail},
        goto=END
    )

def hitl_approval(state: TicketState) -> Command[Literal[END]]:
    """Hard interrupt: pause for human manager approval."""
    decision = interrupt(
        f"Approve license provision for {state['user_email']}? "
        f"Ticket: {state['ticket_id']}. (yes/no)"
    )
    trail = state["audit_trail"] + [f"HITL decision: {decision}"]
    if decision == "yes":
        return Command(update={"action_result": "Approved & provisioned", "audit_trail": trail}, goto=END)
    return Command(update={"action_result": "Rejected by manager", "audit_trail": trail}, goto=END)

def escalate(state: TicketState) -> dict:
    """Route complex issues to human L2 support."""
    audit_log.info(f"[{state['ticket_id']}] Escalated to L2 support")
    return {"action_result": "Escalated to L2 human agent"}

# Build the graph
builder = StateGraph(TicketState)
builder.add_node("classify_ticket", classify_ticket)
builder.add_node("execute_action", execute_action)
builder.add_node("hitl_approval", hitl_approval)
builder.add_node("escalate", escalate)

builder.add_edge(START, "classify_ticket")
builder.add_edge("escalate", END)

# Compile with checkpointer for time-travel & interrupt support
memory = MemorySaver()
graph = builder.compile(checkpointer=memory)

5. Measuring ROI: The Metrics That Matter

Enterprise leadership doesn't approve budgets based on "resolution time." They need cost efficiency, SLA compliance, and audit readiness. Here's the real-world data from production deployments:

Metric 2025 Pilot (RAG-Based) 2026 Production (Action-Oriented) Impact
Resolution Time 4.5 hours (human-assisted) 12 minutes (autonomous) -95%
Cost per Ticket $22.00 (L1 human agent) $1.40 (agent + API costs) -94%
SLA Attainment 72% (missed targets on weekends) 99.2% (24/7 autonomous) +27%
Escalation Rate 85% (chatbot couldn't act) 28% (only complex issues) -57%
System Access Model Read-Only (RAG) Read/Write (Tool Calling + APIs) Transformative
Audit Compliance Manual log review (quarterly) Real-time WORM audit trail Regulatory Ready

💡 Key Takeaway

The ROI leap from pilot to production is driven not by the LLM itself, but by the integration depth (API + UI automation), governance infrastructure (dual-token auth, HITL), and 24/7 availability. Organizations that skip the governance layer in pursuit of speed will face compliance failures that negate any cost savings.

Agentes de IA: Del Piloto a la Producción en 2026

El panorama de la IA empresarial ha cambiado drásticamente. Mediados de 2026 marca el punto de inflexión donde las organizaciones pasan de chatbots conversacionales a flujos de trabajo agénticos orientados a la acción y compatibles con la gobernanza.

⚡ Resumen — La Realidad Empresarial de los Agentes en 2026

  • 🚀 Fin de los Pilotos: Las empresas exigen agentes orientados a la acción que ejecuten flujos de trabajo, no solo recuperen información (RAG → Acción).
  • 🔗 iPaaS Agéntico: La fusión de RPA e IA crea un nuevo paradigma — agentes que operan tanto APIs modernas como UIs heredadas mediante Modelos de Visión-Lenguaje (VLM).
  • 🔐 Gobernanza Dual-Token: Los agentes en producción requieren credenciales del sistema y tokens OAuth del usuario para prevenir escalación de privilegios.
  • 📊 ROI Comprobado: El soporte IT de Nivel 1 automatizado genera $3.40 de retorno por cada dólar, con el costo por ticket cayendo de $22 a $1.40.

1. De RAG a Acción: El Cambio de Paradigma

En 2025, el patrón dominante era RAG (Generación Aumentada por Recuperación): los agentes podían leer datos empresariales y responder preguntas. En 2026, la expectativa cambió a Agentes Orientados a la Acción — sistemas que no solo recuperan, sino que ejecutan: restablecen contraseñas, aprovisionan licencias, actualizan registros CRM y despliegan código.

Este cambio introduce un perfil de riesgo fundamentalmente diferente. Un agente de solo lectura que alucina produce una respuesta incorrecta; un agente orientado a la acción que alucina puede eliminar una base de datos o aprobar una transacción fraudulenta.

DimensiónPiloto 2025 (RAG)Producción 2026 (Acción)
Función PrincipalRecuperación y resumen de informaciónEjecución autónoma de tareas y automatización
Acceso al SistemaSolo lectura (BD vectorial)Lectura/Escritura (APIs, bases de datos, UI)
Modo de FalloRespuesta incorrecta (bajo impacto)Acción incorrecta (alto impacto — pérdida de datos)
GobernanzaFiltrado de contenido opcionalHITL obligatorio, RBAC, auditoría inmutable

2. Integración con Sistemas Heredados: La Arquitectura "iPaaS Agéntico"

El mayor bloqueador no es el LLM — son los sistemas heredados. ERP monolíticos, terminales mainframe y herramientas internas carecen de APIs modernas. La solución de 2026 es una arquitectura de integración de dos frentes:

⬆️ Top-Down: Capa Semántica

Para sistemas con APIs REST/SOAP, las empresas despliegan una Capa Semántica que traduce endpoints crudos en Especificaciones de Herramientas OpenAPI amigables para el LLM.

Herramientas: Hasura DDN, Apollo GraphQL Federation

⬇️ Bottom-Up: RPA Generativo (UI-Agent)

Para sistemas sin API, los agentes VLM (Modelo de Visión-Lenguaje) interactúan directamente con la interfaz visual, tomando capturas de pantalla y ejecutando acciones de clic/escritura.

Herramientas: Anthropic Computer Use, Microsoft UFO, UiPath Autopilot

3. Gobernanza y Seguridad: Construyendo Confianza

La principal preocupación de CISOs y CTOs empresariales es: "¿Qué impide que el agente haga algo catastrófico?" La respuesta es una arquitectura de seguridad en capas con tres componentes no negociables:

🔐 Autenticación Dual-Token

Cada acción del agente debe llevar dos credenciales simultáneamente: el Token del Sistema del Agente y el Token OAuth del Usuario. Esto previene la escalación de privilegios.

📜 Registros de Auditoría Inmutables

Toda la actividad del agente — incluyendo la Cadena de Pensamiento (CoT), parámetros de herramientas y resultados — debe escribirse en un registro de auditoría WORM (Write-Once, Read-Many) en tiempo real.

⛔ Interrupciones HITL (Human-in-the-Loop)

Las acciones críticas (transacciones >$5K, despliegues, exportación de PII) deben activar una interrupción dura. El agente pausa y espera aprobación humana explícita.

4. Case Study: IT Support — From Chatbot to Agentic Workflow

In Q1 2026, a Fortune 500 financial services company transitioned their IT Helpdesk from a GPT-powered chatbot (which could only answer questions about IT policies) to a full agentic workflow that autonomously executes Tier-1 support tasks: password resets, software license provisioning, VPN certificate renewal, and intelligent escalation routing.

KI-Agenten: Vom Pilotprojekt in die Produktion 2026

Die KI-Landschaft im Unternehmen hat sich dramatisch verändert. Mitte 2026 markiert den Wendepunkt, an dem Organisationen von Konversations-Chatbots zu handlungsorientierten, governance-konformen agentischen Workflows übergehen.

⚡ Kurzfassung — Die Unternehmens-KI-Realität 2026

  • 🚀 Pilotphase vorbei: Unternehmen fordern handlungsorientierte Agenten, die Workflows ausführen, nicht nur Informationen abrufen (RAG → Aktion).
  • 🔗 Agentisches iPaaS entsteht: Die Fusion von RPA und KI schafft ein neues Paradigma — Agenten, die sowohl moderne APIs als auch Legacy-UIs über Vision-Language-Modelle (VLMs) bedienen.
  • 🔐 Dual-Token-Governance: Produktionsagenten benötigen sowohl System-Credentials als auch Benutzer-OAuth-Tokens gegen Rechteeskalation.
  • 📊 Bewiesener ROI: Tier-1-IT-Automatisierung erzielt $3,40 Rendite pro Dollar, Kosten pro Ticket sinken von $22 auf $1,40.

1. Von RAG zu Aktion: Der Paradigmenwechsel

2025 dominierte RAG (Retrieval-Augmented Generation): Agenten konnten Unternehmensdaten lesen und Fragen beantworten. 2026 hat sich die Erwartung zu Handlungsorientierten Agenten verschoben — Systeme, die nicht nur abrufen, sondern ausführen: Passwörter zurücksetzen, Lizenzen bereitstellen, CRM-Datensätze aktualisieren und Code deployen.

Diese Verschiebung führt ein fundamental anderes Risikoprofil ein. Ein schreibgeschützter Agent, der halluziniert, liefert eine falsche Antwort; ein handlungsorientierter Agent, der halluziniert, kann eine Datenbank löschen oder betrügerische Transaktionen genehmigen.

FehlermodusFalsche Antwort (geringer Einfluss)Falsche Aktion (hoher Einfluss — Datenverlust)
GovernanceOptionale InhaltsfilterungPflicht-HITL, RBAC, unveränderliche Audit-Trails

2. Legacy-Systeme verbinden: Die "Agentische iPaaS"-Architektur

Der häufigste Blocker ist nicht das LLM — es sind die Legacy-Systeme. Monolithische ERPs und Mainframe-Terminals der 2000er haben keine modernen APIs. Die Lösung 2026 ist eine zweistufige Integrationsarchitektur:

⬆️ Top-Down: Semantische Schicht

Für Systeme mit REST/SOAP-APIs setzt die Semantische Schicht rohe API-Endpunkte in LLM-freundliche OpenAPI-Tool-Spezifikationen um.

Tools: Hasura DDN, Apollo GraphQL Federation

⬇️ Bottom-Up: Generatives RPA (UI-Agent)

Für Systeme ohne API interagieren VLM-Agenten direkt mit der Benutzeroberfläche über Screenshots und Klick-/Tipp-Aktionen.

Tools: Anthropic Computer Use, Microsoft UFO, UiPath Autopilot

3. Governance & Sicherheit: Vertrauen aufbauen

Die größte Sorge von CISOs und CTOs: "Was verhindert, dass der Agent etwas Katastrophales tut?" Die Antwort ist eine mehrschichtige Sicherheitsarchitektur:

🔐 Dual-Token-Authentifizierung

Jede Agent-Aktion muss zwei Credentials gleichzeitig tragen: den Agent-System-Token und den Benutzer-OAuth-Token. Dies verhindert Rechteeskalation.

📜 Unveränderliche Audit-Trails

Alle Agent-Aktivitäten — einschließlich Chain-of-Thought (CoT), Tool-Parameter und Ergebnisse — müssen in Echtzeit in ein WORM-Audit-Log geschrieben werden.

⛔ HITL-Unterbrechungen

Kritische Aktionen (Transaktionen >$5K, Deployments, PII-Export) müssen eine harte Unterbrechung auslösen. Der Agent pausiert und wartet auf explizite menschliche Genehmigung.

4. Case Study: IT Support — From Chatbot to Agentic Workflow

In Q1 2026, a Fortune 500 financial services company transitioned their IT Helpdesk from a GPT-powered chatbot (which could only answer questions about IT policies) to a full agentic workflow that autonomously executes Tier-1 support tasks: password resets, software license provisioning, VPN certificate renewal, and intelligent escalation routing.

AIエージェント：パイロットから本番環境へ（2026年）

エンタープライズAIの状況は劇的に変化しました。2026年半ばは、組織が会話型チャットボットから、アクション指向でガバナンスに準拠したエージェント型ワークフローへと移行する転換点です。

⚡ 要約 — 2026年エンタープライズAIエージェントの現実

  • 🚀 パイロットは終了: 企業は情報検索だけでなく、ワークフローを実行するアクション指向のエージェントを要求しています（RAG → アクション）。
  • 🔗 Agentic iPaaSの台頭: RPAとAIエージェントの融合により、モダンAPIとレガシーUIの両方をVLM（視覚言語モデル）で操作できる新しい統合パラダイムが生まれています。
  • 🔐 デュアルトークンガバナンス: 本番環境のエージェントは、権限昇格を防ぐためにシステム認証情報とユーザーOAuthトークンの両方が必要です。
  • 📊 実証済みROI: Tier-1 ITサポートの自動化は1ドルあたり$3.40のリターン、チケットあたりのコストは$22から$1.40に低下。

1. RAGからアクションへ：パラダイムシフト

2025年の主要パターンはRAG（検索拡張生成）でした：エージェントは企業データを読み取り、質問に回答できました。2026年には期待がアクション指向エージェントに移行しました。パスワードのリセット、ライセンスのプロビジョニング、CRMレコードの更新、コードのデプロイを実行するシステムです。

この変化は根本的に異なるリスクプロファイルをもたらします。読み取り専用のエージェントが幻覚を起こすと誤った回答が生成されますが、アクション指向のエージェントが幻覚を起こすとデータベースの削除や不正取引の承認につながる可能性があります。

次元2025年パイロット（RAG）2026年本番（アクション）
主要機能情報の検索と要約自律的なタスク実行とワークフロー自動化
システムアクセス読み取り専用（ベクターDB）読み書き（API、データベース、UI）
障害モード誤回答（低影響）誤操作（高影響 — データ損失、コンプライアンス違反）
ガバナンス任意のコンテンツフィルタリング必須HITL、RBAC、不変の監査証跡

2. レガシーシステムとの橋渡し：「Agentic iPaaS」アーキテクチャ

最大のブロッカーはLLMではなく、レガシーシステムランドスケープです。モノリシックERP、メインフレーム端末にはモダンAPIがありません。2026年のソリューションは二方向の統合アーキテクチャです：

⬆️ トップダウン：セマンティックゲートウェイ

REST/SOAP APIを持つシステムに対して、セマンティックレイヤーがAPIエンドポイントをLLMフレンドリーなOpenAPI Tool仕様に変換します。

ツール: Hasura DDN, Apollo GraphQL Federation

⬇️ ボトムアップ：生成型RPA（UIエージェント）

APIのないシステムに対して、VLM（視覚言語モデル）エージェントがスクリーンショットを取得し、UIを視覚的に理解してクリック/入力操作を実行します。

ツール: Anthropic Computer Use, Microsoft UFO, UiPath Autopilot

3. ガバナンスとセキュリティ：信頼の構築

企業のCISOとCTOの最大の懸念は：「エージェントが壊滅的なことをするのを何が防ぐのか？」 答えは、3つの譲れない要素を持つ多層セキュリティアーキテクチャです：

🔐 デュアルトークン認証

すべてのエージェントアクションは2つの認証情報を同時に保持する必要があります：エージェントシステムトークンとユーザーOAuthトークン。これにより権限昇格を防止します。

📜 不変の監査証跡

すべてのエージェント活動（思考連鎖（CoT）、ツールパラメータ、結果を含む）は、リアルタイムでWORM（一度書き込み、多数読み取り）監査ログに書き込まれる必要があります。

⛔ HITL（ヒューマンインザループ）インタラプトゲート

クリティカルなアクション（$5K超の取引、本番デプロイ、PII データのエクスポート）はハードインタラプトをトリガーする必要があります。エージェントは一時停止し、明示的な人間の承認を待ちます。

4. Case Study: IT Support — From Chatbot to Agentic Workflow

In Q1 2026, a Fortune 500 financial services company transitioned their IT Helpdesk from a GPT-powered chatbot (which could only answer questions about IT policies) to a full agentic workflow that autonomously executes Tier-1 support tasks: password resets, software license provisioning, VPN certificate renewal, and intelligent escalation routing.

The implementation uses LangGraph with the latest Command API for state updates, interrupt() for HITL approval on sensitive operations, and structured tool calling with audit logging.

from typing import Literal
from typing_extensions import TypedDict
from langgraph.graph import StateGraph, START, END
from langgraph.types import Command, interrupt
from langgraph.checkpoint.memory import MemorySaver

# Immutable audit logger (write to WORM-compliant store)
audit_log = logging.getLogger("agent.audit")

class TicketState(TypedDict):
    ticket_id: str
    user_email: str
    issue_type: str        # classified by the agent
    action_result: str
    requires_approval: bool
    audit_trail: list[str]

def classify_ticket(state: TicketState) -> Command[Literal["execute_action", "escalate"]]:
    """Use LLM tool-calling to classify the ticket intent."""
    # In production: call LLM with structured output
    issue = "password_reset"  # simplified
    audit_log.info(f"[{state['ticket_id']}] Classified as: {issue}")

    if issue in ("password_reset", "license_provision", "vpn_renewal"):
        return Command(
            update={"issue_type": issue, "audit_trail": [f"Classified: {issue}"]},
            goto="execute_action"
        )
    return Command(

    )

def execute_action(state: TicketState) -> Command[Literal["hitl_approval", END]]:
    """Execute the Tier-1 action via enterprise tool APIs."""
    if state["issue_type"] == "password_reset":
        # Dual-token auth: agent_token + user_oauth_token
        result = "Password reset link sent to user"
        needs_approval = False
    elif state["issue_type"] == "license_provision":
        result = "License provisioned (pending approval)"
        needs_approval = True  # costs money → requires HITL
    else:
        result = "VPN certificate renewed"
        needs_approval = False

    trail = state["audit_trail"] + [f"Action: {result}"]
    audit_log.info(f"[{state['ticket_id']}] {result}")

    if needs_approval:
        return Command(
            update={"action_result": result, "requires_approval": True, "audit_trail": trail},
            goto="hitl_approval"
        )
    return Command(
        update={"action_result": result, "requires_approval": False, "audit_trail": trail},
        goto=END
    )

def hitl_approval(state: TicketState) -> Command[Literal[END]]:
    """Hard interrupt: pause for human manager approval."""
    decision = interrupt(
        f"Approve license provision for {state['user_email']}? "
        f"Ticket: {state['ticket_id']}. (yes/no)"
    )
    trail = state["audit_trail"] + [f"HITL decision: {decision}"]
    if decision == "yes":
        return Command(update={"action_result": "Approved & provisioned", "audit_trail": trail}, goto=END)
    return Command(update={"action_result": "Rejected by manager", "audit_trail": trail}, goto=END)

def escalate(state: TicketState) -> dict:
    """Route complex issues to human L2 support."""
    audit_log.info(f"[{state['ticket_id']}] Escalated to L2 support")
    return {"action_result": "Escalated to L2 human agent"}

# Build the graph
builder = StateGraph(TicketState)
builder.add_node("classify_ticket", classify_ticket)
builder.add_node("execute_action", execute_action)
builder.add_node("hitl_approval", hitl_approval)
builder.add_node("escalate", escalate)

builder.add_edge(START, "classify_ticket")
builder.add_edge("escalate", END)

# Compile with checkpointer for time-travel & interrupt support
memory = MemorySaver()
graph = builder.compile(checkpointer=memory)
