=== 2.1 Product Perspective ===

ModMan is a core component of the Logos Microkernel ecosystem, responsible for managing the discovery, distribution, and lifecycle of all system modules. It operates in a fully decentralized manner without central repositories, utilizing peer-to-peer networking for module distribution and the PDMS (as a persistent decentralized metadata store) for metadata management.

Key characteristics:
* Fully decentralized architecture with no central repositories
* Content-based routing rather than location-based addressing
* Semantic-based peer clustering for efficient content discovery
* Distributed caching for improved performance and availability
* Support for both push (notifications) and pull (search) operations

The system interfaces with:
* Logos Microkernel: For module deployment and runtime management
* PDMS: For handling dependency resolution and versioning metadata
* Codex: For file-sharing and content delivery
* Other ModMan instances: For peer-to-peer module distribution
