System Architecture

ServoAgent is organized around a control plane, an execution runtime, an integration plane, and an operations loop that keeps production systems observable and recoverable.

Layer 1

Control Plane

Owns workspace auth, configuration, policy enforcement, and release coordination before work reaches an agent runtime.

Layer 2

Agent Runtime

Executes plans, tools, and guarded model calls while preserving state, retries, and recovery logic.

Layer 3

Integration Plane

Connects agents to SaaS systems and event streams with scoped credentials, retries, and auditability.

Layer 4

Operations Loop

Surrounds production traffic with deployment automation, rollback paths, observability, and post-incident evidence.

Execution lifecycle

1. Request entry

Traffic enters through the API, SDKs, or triggered workflows and is tagged with identity plus request metadata.

2. Policy and config resolution

Workspace feature flags, environment variables, scopes, and guardrails are resolved before execution starts.

3. Agent execution

The runtime plans work, calls tools and models, and records step-level state transitions for recovery and inspection.

4. Side-effect handling

Outbound connector actions and webhook emissions are executed with retry-safe controls and audit logging.

5. Operations feedback

Deployment, reliability, and compliance systems consume execution telemetry to drive rollback, alerting, and review.

Design principles

Scoped by default

Auth, secrets, and feature exposure are resolved per workspace and environment instead of globally.

Recoverable workflows

Execution paths assume network failures, replay, and partial completion, so retries and rollback are first-class concerns.

Observable operations

Request IDs, audit records, deployment events, and runtime traces are treated as product requirements, not optional logs.
