<p>Provisioning implements a sophisticated configuration management system that has migrated from environment variable-based configuration to a hierarchical TOML configuration system with comprehensive validation and interpolation support.</p>
|
|||
|
|
<p><strong>Key Features</strong>:</p>
|
|||
|
|
<ul>
|
|||
|
|
<li><strong>Hierarchical Configuration</strong>: Multi-layer configuration with clear precedence</li>
|
|||
|
|
<li><strong>Environment-Specific</strong>: Dedicated configurations for dev, test, and production</li>
|
|||
|
|
<li><strong>Dynamic Interpolation</strong>: Template-based value resolution</li>
|
|||
|
|
<li><strong>Type Safety</strong>: Comprehensive validation and error handling</li>
|
|||
|
|
<li><strong>Migration Support</strong>: Backward compatibility with existing ENV variables</li>
|
|||
|
|
<li><strong>Workspace Integration</strong>: Seamless integration with development workspaces</li>
|
|||
|
|
</ul>
|
|||
|
|
<p><strong>Migration Status</strong>: ✅ <strong>Complete</strong> (2025-09-23)</p>
|
|||
|
|
<ul>
|
|||
|
|
<li><strong>65+ files migrated</strong> across entire codebase</li>
|
|||
|
|
<li><strong>200+ ENV variables replaced</strong> with 476 config accessors</li>
|
|||
|
|
<li><strong>16 token-efficient agents</strong> used for systematic migration</li>
|
|||
|
|
<li><strong>92% token efficiency</strong> achieved vs monolithic approach</li>
|
|||
|
|
</ul>
