Question:

How to implement the 6-phase module generation pipeline in Vitto?

Task: Session 108: Port gmodules1 generation pipeline to Vitto

🎯 Decision Made

Chosen:

Created a complete NestJS module (ModuleGenerationModule) with 6 sequential phase services (Enhance → Analyze → Decompose → Plan → Execute → Integrate), a phase executor with SSE streaming, session manager, and REST+SSE controller. Dual-path output: Path A generates ModuleContext JSON for visual Builder, Path B generates actual Angular code files. 10 .prompt.md templates adapted from gmodules1, with shared AI rules context auto-injected.

Options Considered:

• No alternatives documented

💭 Reasoning

gmodules1 proved the 6-phase pipeline produces high-quality platforms. Porting this to Vitto with NestJS architecture follows existing patterns (PhaseExecutorService, ProviderFactoryService). Dual-path output supports both visual editing (Builder/Workbench) and vibe coding (actual Angular files). SSE streaming provides real-time progress to the frontend GenerationHubService. The PhaseOrchestrationResult format was kept compatible with the existing PhaseResultToModuleContextAdapter (430 lines) so no adapter changes needed.
