Package Manager	Core Infrastructure	0	Infrastructure

Decentralized package manager for discovering, resolving, and retrieving Logos modules. Acts as an index layer over engineering/infrastructure_essentials/logos_storage, providing versioning, dependency resolution, and module metadata management.

FURPS+

Functionality

• Maintain an index of available modules with metadata (name, version, dependencies, platform)
• Resolve module dependencies and version constraints
• Retrieve module packages from engineering/infrastructure_essentials/logos_storage by CID
• Verify module integrity and signatures before installation
• Support semantic versioning and version ranges
• Enable module publishing with automatic indexing
• Provide CLI and programmatic interfaces for module operations

Usability

• Simple commands: logos install <module>, logos update, logos publish
• Lockfile support for reproducible installations
• Clear dependency tree visualization
• Helpful error messages for resolution conflicts

Reliability

• Cache module metadata locally for offline resolution
• Handle unavailable storage nodes gracefully
• Support multiple registry sources for redundancy
• Verify module hashes before installation

Performance

• Parallel module downloads
• Incremental updates for changed modules only
• Efficient index syncing with minimal bandwidth
• Local caching of frequently used modules

+ (Privacy, Anonymity, Censorship-Resistance)

• Censorship-Resistance: Module binaries stored on engineering/infrastructure_essentials/logos_storage cannot be taken down
• Privacy: Index queries don't reveal user identity or installation patterns
• Anonymity: Retrieve modules without disclosing IP address (when using anonymous storage access)
• Decentralization: Multiple independent registries prevent single point of control
• Integrity: Content-addressed storage ensures received modules match requested versions

Demand Validation

Potential Users: All Logos developers, module publishers, Logos App, build systems

Use Cases:

• Installing modules for engineering/application_essentials/logos_core_devex
• Fetching dependencies during engineering/application_essentials/logos_core_devex builds
• Publishing new modules to the ecosystem
• Resolving module versions for reproducible builds
• Updating modules to newer versions
• Auditing module dependencies for security

Index Structure

The package manager maintains a decentralized index that maps module identifiers to their storage locations:

{
  "registry_version": "1.0",
  "modules": {
    "chat_module": {
      "versions": {
        "1.0.0": {
          "cid": "Qm...",
          "dependencies": {"waku_module": "^2.0.0"},
          "platforms": ["linux-x64", "darwin-x64", "win-x64"],
          "signature": "0x...",
          "published": "2027-01-15T10:30:00Z"
        },
        "1.1.0": { ... }
      },
      "latest": "1.1.0"
    }
  }
}

Storage Layer

Module binaries are stored on engineering/infrastructure_essentials/logos_storage:

• Each module version is a content-addressed package (tar.gz)
• CID ensures integrity and enables deduplication
• Multiple storage providers can host the same module
• Package manager resolves CID from index, then fetches from storage

CLI Interface

# Install a module
logos install chat_module

# Install specific version
logos install chat_module@1.0.0

# Update all modules
logos update

# Publish a module
logos publish ./my_module

# List installed modules
logos list

# Show module info
logos info chat_module

Components

• Registry Client: Syncs and queries the decentralized module index
• Resolver: Computes dependency graph and resolves version constraints
• Storage Client: Retrieves modules from engineering/infrastructure_essentials/logos_storage by CID
• Installer: Unpacks and installs modules to appropriate locations
• Publisher: Packages modules and updates registry index
• Verifier: Validates signatures and integrity hashes

Technical Validation

Risks & Challenges:

• Maintaining index consistency across decentralized registries
• Handling conflicting module versions from different publishers
• Preventing malicious packages in a permissionless system
• Managing platform-specific binaries efficiently
• Ensuring registry availability and performance
• Balancing decentralization with curation quality

Dependencies:

• engineering/infrastructure_essentials/logos_storage for module binary hosting

Integration Points:

• engineering/infrastructure_essentials/logos_storage for content-addressed module storage
• engineering/infrastructure_essentials/logos_core for module installation and loading
• engineering/application_essentials/logos_core_devex for module retrieval and distribution
• Build systems (CMake, npm, cargo) for integration
