+# Design Document
+
+## Overview
+
+This design extends getpkg to support multiple package servers while maintaining full backward compatibility. The solution introduces a server configuration system, updates the client architecture to handle multiple servers, and reorganizes package metadata storage. The design prioritizes minimal disruption to existing functionality while providing powerful multi-server capabilities.

+
+## Components and Interfaces
+
+### ServerManager Class
+
+**Purpose**: Manages server configuration, write tokens, and provides server list to other components.
+
+**Interface**:
+```cpp
+class ServerManager {
+public:
+    ServerManager();
+    
+    // Server management
+    bool addServer(const std::string& serverUrl, const std::string& writeToken = "");
+    bool removeServer(const std::string& serverUrl);
+    std::vector<std::string> getServers() const;
+    std::string getDefaultServer() const;
+    std::string getDefaultPublishServer() const;  // First server with write token
+    
+    // Token management
+    bool setWriteToken(const std::string& serverUrl, const std::string& token);
+    std::string getWriteToken(const std::string& serverUrl) const;
+    bool hasWriteToken(const std::string& serverUrl) const;
+    std::vector<std::string> getServersWithTokens() const;
+    
+    // Configuration
+    bool loadConfiguration();
+    bool saveConfiguration();
+    void ensureDefaultConfiguration();
+    
+    // Migration
+    bool migrateFromLegacy();
+    
+private:
+    std::vector<ServerConfig> servers_;
+    std::filesystem::path configPath_;
+    
+    bool validateServerUrl(const std::string& url) const;
+    bool isServerReachable(const std::string& url) const;
+    ServerConfig* findServer(const std::string& url);
+};
+```
+
+### Enhanced GetbinClient Class
+
+**Purpose**: Extended to support multiple servers with fallback logic.
+
+**Interface Changes**:
+```cpp
+class GetbinClient {
+public:
+    GetbinClient(const std::vector<std::string>& servers);
+    
+    // Existing methods with server selection
+    bool download(const std::string& toolName, const std::string& arch, 
+                  const std::string& outPath, ProgressCallback progressCallback = nullptr);
+    bool downloadFromServer(const std::string& serverUrl, const std::string& toolName, 
+                           const std::string& arch, const std::string& outPath, 
+                           ProgressCallback progressCallback = nullptr);
+    
+    // Server-specific operations
+    bool upload(const std::string& serverUrl, const std::string& archivePath, 
+                std::string& outUrl, std::string& outHash, const std::string& token,
+                ProgressCallback progressCallback = nullptr);
+    bool getHash(const std::string& serverUrl, const std::string& toolName, 
+                 const std::string& arch, std::string& outHash);
+    
+    // Multi-server operations
+    bool findPackageServer(const std::string& toolName, const std::string& arch, 
+                          std::string& foundServer) const;
+    
+private:
+    std::vector<std::string> servers_;
+    std::string buildUrl(const std::string& serverUrl, const std::string& endpoint) const;
+};
+```
+
+### PackageMetadata Structure
+
+**Purpose**: Enhanced metadata structure to track server source.
+
+**Structure**:
+```cpp
+struct PackageMetadata {
+    std::string name;
+    std::string version;
+    std::string hash;
+    std::string arch;
+    std::string sourceServer;  // New field
+    std::string installDate;   // New field for better tracking
+    
+    // Serialization
+    nlohmann::json toJson() const;
+    static PackageMetadata fromJson(const nlohmann::json& j);
+    
+    // Migration support
+    static PackageMetadata fromLegacyJson(const nlohmann::json& j, const std::string& defaultServer);
+};
+```
+
+### Migration Manager
+
+**Purpose**: Handles migration from single-server to multi-server configuration.
+
+**Interface**:
+```cpp
+class MigrationManager {
+public:
+    MigrationManager();
+    
+    bool needsMigration() const;
+    bool performMigration();
+    
+private:
+    bool migrateServerConfiguration();
+    bool migratePackageMetadata();
+    bool movePackageFiles();
+    bool updatePackageMetadata();
+    
+    std::filesystem::path oldConfigDir_;
+    std::filesystem::path newConfigDir_;
+    std::filesystem::path packagesDir_;
+};
+```
+
+## Data Models
+
+### Server Configuration Format
+
+**File**: `~/.config/getpkg/servers.json`
+
+```json
+{
+  "version": "1.0",
+  "servers": [
+    {
+      "url": "getpkg.xyz",
+      "name": "Official getpkg Registry",
+      "default": true,
+      "writeToken": "",
+      "added": "2024-01-15T10:30:00Z"
+    },
+    {
+      "url": "packages.example.com",
+      "name": "Example Corporate Registry",
+      "default": false,
+      "writeToken": "abc123token456",
+      "added": "2024-01-16T14:20:00Z"
+    }
+  ],
+  "lastUpdated": "2024-01-16T14:20:00Z"
+}
+```
+
+### Enhanced Package Metadata Format
+
+**File**: `~/.config/getpkg/packages/<tool_name>.json`
+
+```json
+{
+  "name": "example-tool",
+  "version": "2024.0115.1430",
+  "hash": "1234567890123456",
+  "arch": "x86_64",
+  "sourceServer": "getpkg.xyz",
+  "installDate": "2024-01-15T14:30:00Z",
+  "lastUpdated": "2024-01-15T14:30:00Z"
+}
+```
+
+### Directory Structure Changes
+
+```
+~/.config/getpkg/
+├── servers.json              # New: Server configuration with embedded tokens
+├── packages/                 # New: Package metadata directory
+│   ├── tool1.json
+│   ├── tool2.json
+│   └── ...
+└── getpkg.xyz/              # Legacy: Will be migrated to servers.json
+    └── write_token.txt       # Legacy: Will be migrated
+```
+
+## Error Handling
+
+### Server Connectivity Issues
+
+1. **Network Failures**: Graceful fallback to next server in list
+2. **Invalid Responses**: Clear error messages with server identification
+3. **Authentication Failures**: Server-specific error handling with token guidance
+
+### Configuration Corruption
+
+1. **Invalid JSON**: Automatic backup and reset to default configuration
+2. **Missing Files**: Automatic creation with default settings
+3. **Permission Issues**: Clear error messages with resolution steps
+
+### Migration Failures
+
+1. **Partial Migration**: Rollback capability with clear status reporting
+2. **File Conflicts**: Safe handling with backup creation
+3. **Metadata Corruption**: Individual file recovery without breaking entire system
+
+## Testing Strategy
+
+### Unit Tests
+
+1. **ServerManager**: Configuration loading, validation, server management
+2. **GetbinClient**: Multi-server communication, fallback logic
+3. **PackageMetadata**: Serialization, migration, validation
+4. **MigrationManager**: Legacy data handling, file operations
+
+### Integration Tests
+
+1. **End-to-End Installation**: Multi-server package discovery and installation
+2. **Server Management**: Add/remove servers with real configuration
+3. **Migration Testing**: Legacy to new format conversion
+4. **Publish/Unpublish**: Server-specific operations
+
+### Compatibility Tests
+
+1. **Backward Compatibility**: Existing installations continue working

+# Requirements Document
+
+## Introduction
+
+This feature extends getpkg to support multiple package servers instead of being limited to only getpkg.xyz. Users will be able to add and remove package servers, with getpkg searching across all configured servers to find packages. The system will maintain backward compatibility while providing flexible server management capabilities.
+
+## Requirements
+
+### Requirement 1
+
+**User Story:** As a developer, I want to configure multiple package servers, so that I can access packages from different repositories and have redundancy in case one server is unavailable.
+
+#### Acceptance Criteria
+
+1. WHEN I run `getpkg server add <server_url>` THEN the system SHALL add the server to the configuration and confirm the addition
+2. WHEN I run `getpkg server remove <server_url>` THEN the system SHALL remove the server from the configuration and confirm the removal
+3. WHEN I run `getpkg server list` THEN the system SHALL display all configured servers in the order they were added
+4. WHEN no servers are configured THEN the system SHALL default to using getpkg.xyz as the primary server
+5. WHEN I add the first custom server THEN getpkg.xyz SHALL remain as the default first server unless explicitly removed
+
+### Requirement 2
+
+**User Story:** As a user, I want getpkg to search across all configured servers when installing packages, so that I can access packages from any of my configured repositories.
+
+#### Acceptance Criteria
+
+1. WHEN I run `getpkg install <tool_name>` THEN the system SHALL search servers in the order they were configured
+2. WHEN a package is found on the first server THEN the system SHALL install from that server and not check remaining servers
+3. WHEN a package is not found on the first server THEN the system SHALL try the next server in order
+4. WHEN a package is not found on any server THEN the system SHALL report that the package was not found
+5. WHEN checking for updates THEN the system SHALL use the same server where the package was originally installed
+
+### Requirement 3
+
+**User Story:** As a package publisher, I want to specify which server to publish to and manage write tokens per server, so that I can control where my packages are distributed and authenticate appropriately.
+
+#### Acceptance Criteria
+
+1. WHEN I run `getpkg publish <tool_name> <folder>` without specifying a server THEN the system SHALL publish to the first configured server that has a write token
+2. WHEN I run `getpkg publish --server <server_url> <tool_name> <folder>` THEN the system SHALL publish to the specified server using its stored write token
+3. WHEN I run `getpkg unpublish <tool_name>` without specifying a server THEN the system SHALL unpublish from the first configured server that has a write token
+4. WHEN I run `getpkg unpublish --server <server_url> <tool_name>` THEN the system SHALL unpublish from the specified server using its stored write token
+5. WHEN no servers have write tokens THEN the system SHALL report an error and suggest adding a write token to a server
+
+### Requirement 4
+
+**User Story:** As a user, I want my package metadata to be organized by server, so that I can track which packages came from which servers and manage them appropriately.
+
+#### Acceptance Criteria
+
+1. WHEN a package is installed THEN the system SHALL store the package metadata in `~/.config/getpkg/packages/<tool_name>.json`
+2. WHEN package metadata is stored THEN it SHALL include the source server URL in addition to existing fields
+3. WHEN the packages directory doesn't exist THEN the system SHALL create it automatically
+4. WHEN migrating from the old format THEN existing package JSON files SHALL be moved to the packages subdirectory
+5. WHEN migrating from the old format THEN existing package metadata SHALL be updated to include getpkg.xyz as the source server
+
+### Requirement 5
+
+**User Story:** As a user, I want server configuration to be persistent and secure, so that my settings are maintained across sessions and my authentication tokens are protected.
+
+#### Acceptance Criteria
+
+1. WHEN server configuration is modified THEN it SHALL be stored in `~/.config/getpkg/servers.json`
+2. WHEN the configuration file doesn't exist THEN the system SHALL create it with getpkg.xyz as the default server
+3. WHEN reading server configuration THEN the system SHALL validate the JSON format and handle corruption gracefully
+4. WHEN a server URL is invalid THEN the system SHALL reject the addition and provide a helpful error message
+5. WHEN authentication tokens are needed THEN they SHALL continue to be stored per-server in the existing location pattern
+
+### Requirement 6
+
+**User Story:** As a user, I want the multi-server functionality to be backward compatible, so that existing installations continue to work without modification.
+
+#### Acceptance Criteria
+
+1. WHEN getpkg starts with no server configuration THEN it SHALL automatically configure getpkg.xyz as the default server
+2. WHEN existing package JSON files are found in `~/.config/getpkg/` THEN they SHALL be automatically migrated to the packages subdirectory
+3. WHEN migrated package files are processed THEN they SHALL be updated to include server source information
+4. WHEN all existing functionality is used THEN it SHALL work exactly as before for users who don't configure additional servers
+5. WHEN the migration process fails THEN the system SHALL provide clear error messages and not break existing functionality

+## Multi-Server Architecture
+
+getpkg supports multiple package servers with intelligent fallback:
+
+1. **Server Configuration**
+   - Multiple servers can be configured
+   - Each server can have an optional write token
+   - First server with token becomes default publish target
+
+2. **Download Strategy**
+   - Attempts servers in configured order
+   - Falls back to next server on failure
+   - Tracks which server provided each package
+
+3. **Publishing**
+   - Requires SOS_WRITE_TOKEN environment variable
+   - Publishes to first server with valid token
+   - Supports architecture-specific uploads
+
+## Security Considerations
+
+- No root access required - installs to user home directory
+- Static linking prevents dependency attacks
+- Hash verification for downloaded packages
+- Token-based authentication for publishing
+
+## Testing
+
+- Docker-based test environment for consistency
+- Integration tests for package operations
+- Unit tests for individual components
+- Test artifacts isolated in `test_temp/` directory
+
+## Development Workflow
+
+1. **Local Development**
+   ```bash
+   cd getpkg && ./build.sh              # Build
+   cd getpkg && ./test.sh               # Test
+   ```
+
+2. **Full Build**
+   ```bash
+   ./buildtestpublish_all.sh            # Build all tools
+   ```
+
+3. **Publishing** (requires SOS_WRITE_TOKEN)
+   ```bash
+   export SOS_WRITE_TOKEN="your-token"
+   cd getpkg && ./publish.sh            # Publish single tool
+   ```

 This repository contains Dropshell Tools - a collection of utilities that support dropshell development. The main tool is `getpkg`, a C++ command-line application that manages tool installation, updates, and publishing for the dropshell ecosystem.
 
+## Repository Structure
+
+- **getpkg**: Package manager for dropshell tools (C++23)
+- **sos**: Simple object storage upload utility (Bash)
+- **whatsdirty**: Git repository status checker (Bash)
+- **dehydrate**: File to C++ code generator (C++)
+- **bb64**: Base64 encoder/decoder (C++)
+- **gp**: Git push utility (Bash)

 ## Architecture
 
-### Core Components
+### Core Components (getpkg)
 
 - **getpkg**: Main C++ application (`getpkg/src/`)
   - `main.cpp`: CLI interface and command routing
-  - `ArchiveManager`: Handles .tgz archive creation/extraction
-  - `BashrcEditor`: Manages ~/.bashrc_dropshell_tool script modifications
+  - `GetbinClient`: Multi-server HTTP client for downloading/uploading tools
+  - `PackageMetadata`: Enhanced metadata with server tracking and migration support
+  - `ServerManager`: Manages multiple package servers with write tokens
+  - `BashrcEditor`: Manages ~/.bashrc_getpkg script modifications
   - `DropshellScriptManager`: Manages tool installation and configuration
-  - `GetbinClient`: HTTP client for downloading/uploading tools
+  - `MigrationManager`: Handles legacy format migrations
+  - `common/`: Shared utilities (archive_tgz, hash, output, temp_directory)
 
-- **sos**: Simple object storage utility
-- **whatsdirty**: Git repository status checker
+### Key Features
+
+- **Multi-server support**: Fallback logic for package downloads
+- **Architecture awareness**: Supports x86_64, aarch64, and universal packages
+- **Migration support**: Handles upgrades from legacy single-server format
+- **Static linking**: All tools built as static binaries for portability

 ## Tool Functionality
 
 getpkg manages a tool ecosystem by:
-- Installing tools to `~/.local/bin/getpkg/<tool_name>/`
-- Managing bash completions and aliases via `~/.bashrc_getpkg`
-- Storing tool metadata in `~/.config/getpkg/`
-- Publishing/downloading tools via getbin.xyz object storage
+- Installing tools to `~/.getpkg/<tool_name>/` with symlinks in `~/.local/bin/getpkg/`
+- Managing bash completions and PATH updates via `~/.bashrc_getpkg`
+- Storing tool metadata in `~/.config/getpkg/packages/` (JSON format)
+- Supporting multi-server package distribution with fallback
+- Publishing/downloading tools via object storage servers (default: getpkg.xyz)
+
+## File Locations
+
+- **Tool installations**: `~/.getpkg/<tool_name>/`
+- **Executable symlinks**: `~/.local/bin/getpkg/` (added to PATH)
+- **Package metadata**: `~/.config/getpkg/packages/<tool_name>.json`
+- **Server configuration**: `~/.config/getpkg/servers.json`
+- **Bash integration**: `~/.bashrc_getpkg` (sourced by ~/.bashrc)
 
 ## Publishing Requirements
 
-Publishing requires the `SOS_WRITE_TOKEN` environment variable for authentication to the object storage system.
+Publishing requires the `SOS_WRITE_TOKEN` environment variable for authentication to the object storage system.
+
+## Testing
+
+- Tests create temporary files in `test_temp/` directory
+- Docker-based test environment using same build image
+- Run `cleanup_test_packages.sh` to remove orphaned test packages from servers
+
+## Important Notes
+
+- All builds use static linking for maximum portability
+- Version format is YYYY.MMDD.HHMM (timestamp-based)
+- Tools should support `version` and `autocomplete` subcommands
+- Architecture-specific builds use suffixes like `:x86_64` or `:aarch64`
