=== 1.1 Purpose ===

This Software Requirements Specification (SRS) document provides a detailed description of the Logos P2P Module Package Manager (ModMan). It outlines the functional and non-functional requirements for developing a secure, decentralized package management system that will serve as the primary module for handling module discovery, updates, versioning, and dependency resolution in the Logos Microkernel ecosystem.

=== 1.2 Document Conventions ===

This document follows these conventions:
* MUST/REQUIRED - Indicates a mandatory requirement for MVP
* SHOULD/RECOMMENDED - Indicates a requirement planned for subsequent releases
* MAY/OPTIONAL - Indicates an optional requirement
* TBD - Indicates details that are yet To Be Determined

=== 1.3 Intended Audience and Reading Suggestions ===

This document is intended for:
* Developers implementing the ModMan system
* System architects designing the Logos Microkernel ecosystem
* Security auditors reviewing the system design
* Quality assurance engineers testing the implementation
* Project managers overseeing development

For developers and architects, it is recommended to read the entire document sequentially. QA engineers should focus on sections 4 and 5. Project managers may want to focus on sections 1, 2, and the high-level aspects of section 4.

=== 1.4 Product Scope ===

ModMan is a peer-to-peer system package manager designed specifically for the Logos Microkernel. Its primary purposes are:
* Serve as a decentralized application market for Logos modules
* Provide secure module discovery and distribution
* Handle module versioning and updates
* Manage dependencies between modules
* Support multiple hardware architectures
* Interface with the Logos Microkernel for module deployment
* Interface with the PDMS module for dependency resolution and versioning
* Interface with the Codex module for file-sharing and content delivery
