# Personal AI Infrastructure — Serialization Module

**Version**: v1.2.3 | **Status**: Active | **Last Updated**: March 2026

## Overview

The Serialization module provides multi-format object serialization and deserialization — JSON, YAML, MessagePack, Pickle, and custom formats for data persistence and inter-module communication.

## PAI Capabilities

- JSON/YAML serialization with schema validation
- Binary serialization (MessagePack, Pickle) for performance
- Custom serializer registration for domain types
- Streaming serialization for large datasets
- Schema evolution and versioning support

## Key Exports

| Export | Type | Purpose |
|--------|------|---------|
| Serializers | Various | Format-specific encode/decode |
| Schema validators | Various | Serialization schema enforcement |

## PAI Algorithm Phase Mapping

| Phase | Serialization Contribution |
|-------|----------------------------|
| **EXECUTE** | Serialize/deserialize data for inter-module communication |
| **LEARN** | Persist agent state and memory to durable storage |

## Architecture Role

**Foundation Layer** — Cross-cutting data persistence consumed by `agentic_memory/`, `cache/`, `config_management/`, and `events/`.
