TECHNICAL DEEP-DIVE

How the engine works

Hyphen is built on four layers — each responsible for a distinct concern. Together, they bridge rule-based automation with AI reasoning while keeping everything governed and auditable.

This page is for technical evaluators. For business outcomes, see Solutions. For deployment options, see Enterprise.

L1: RUNTIME

Execution Engine

The core that manages workflow execution, agent reasoning loops, state transitions, and context accumulation across steps.

ReAct Reasoning Loop
Step Executor
Context Accumulator
Tool Resolver
L2: PRIMITIVES

Built-in Processing

Specialized engines for operations that should never rely on LLM inference — matching, validation, human approval, and document handling.

Reconciliation Engine
Human Approval Gateway
Form Validator
Document Pipeline
L3: GOVERNANCE

Security & Compliance

Defense layers that run on every request — sanitizing inputs, redacting sensitive data, and preventing unauthorized agent behavior.

PII Redaction Layer
Prompt Injection Scanner
Egress Filter (SSRF)
Secret Detection
L4: RELIABILITY

Infrastructure

The distributed systems patterns that ensure workflows complete even when things go wrong — server failures, timeouts, and resource exhaustion.

Stale Run Recovery
State Checkpointing
Resource Pool Manager
Dead Letter Queue
THE STACK

Runs on a standard, cloud-agnostic stack

No proprietary runtime, no exotic dependencies — Hyphen runs on the infrastructure your team already operates. Deploy it in your own cloud, on-prem, or fully air-gapped, with no lock-in.
