# Data Processing Flow

Antei transforms unstructured financial and operational data from external systems into validated, compliance-ready records using a structured and secure processing pipeline.

This page outlines how ingestion, extraction, mapping, classification, validation, and storage work together.

***

## Overview of the Flow

<Steps>
  <Step title="1. Data Ingestion">
    Raw data is pulled via integrations (e.g., Stripe, QuickBooks) using scheduled syncs, webhooks, or on-demand jobs. CSV imports are also supported.
  </Step>

  <Step title="2. Extraction Workers">
    Cloudflare Workers standardize and transform raw payloads into structured entities (invoices, transactions, contacts, etc.) with metadata.
  </Step>

  <Step title="3. Mapping & Enrichment">
    Extracted data is mapped to Antei’s internal schema using registry-driven logic. Classification metadata is attached at the field level.
  </Step>

  <Step title="4. Validation Engine">
    Each entity is validated for schema completeness, reference links (e.g., contact → transaction), and duplication. Unprocessed records are flagged.
  </Step>

  <Step title="5. Unprocessed Item Handling">
    Incomplete or unmatched records are moved to the unprocessed queue. Users can review, complete, or override values through manual intervention.
  </Step>

  <Step title="6. Structured Storage">
    Clean, normalized data is written to the system of record with classification and retention rules applied automatically.
  </Step>
</Steps>

## Architecture Snapshot

> 📌 Visual architecture coming soon — this will illustrate how ingestion, workers, and validation modules interact with Xano, Cloudflare, and storage layers.

## Key Guarantees

* ✅ All data is encrypted in transit and at rest
* ✅ No external data is written back to source systems
* ✅ Every step is logged and auditable
* ✅ Each entity is tied to an `extracted_id` and `payload_id` for traceability

## Example Record Lifecycle

```json theme={null}
{
  "payload_id": "pld_29831231",
  "extracted_id": "ext_inv_102",
  "entity_type": "invoice",
  "validation_status": "unprocessed",
  "metadata": {
    "source": "stripe_invoice",
    "sync_frequency": "daily",
    "created_at": "2025-05-13T08:32:10Z"
  },
  "classified_as": "financial",
  "retention_policy": "12 months"
}
```
