**service-extraction** is a Ring 2 knowledge-and-processing service in the PointSav three-ring architecture. It receives raw payloads from Ring 1 ingest services, strips proprietary third-party formatting (JSON, MIME, Base64), and constructs machine-readable Entity Bundles — self-contained directory structures that hold both the text payload and any associated binary attachments. It is the canonical successor to the legacy working name `service-parser`.

## Overview
## Architectural Baseline

Every message that passes through Ring 1 arrives at service-extraction as an unprocessed, vendor-formatted payload. The service has one responsibility: transform that payload into a clean, traceable Entity Bundle and route it to the correct downstream service. It assigns a transaction ID to each bundle, providing a chain-of-custody reference that persists through every subsequent processing step.

service-extraction occupies **Ring 2 — Knowledge and Processing** in the three-ring architecture. Ring 2 is multi-tenant (via `moduleId` namespacing) and deterministic: it processes data without invoking AI inference unless the data shape requires it. When a payload contains unstructured text that cannot be classified by deterministic rules, service-extraction routes that text to Ring 3 (service-slm) for AI-assisted extraction. Structured and semi-structured payloads route entirely within Ring 2.
