📋 Decision Context

Question:

Should the module-gen.completed SSE event include full module data or just summary stats?

Task: Session 109: Fix module-gen.completed SSE event missing data

🎯 Decision Made

Chosen:

Include full modules array and files array in the SSE event payload alongside summary stats

Options Considered:

1. Summary stats only (broken — frontend gets no modules)
2. Full module + file data in SSE event (chosen)
3. Separate REST endpoint to fetch results after completion

💭 Reasoning

Without the actual module data in the SSE event, the frontend has no way to receive generated modules — it would need a separate REST call to fetch them, adding complexity and race conditions. The SSE stream already carries phase data throughout the pipeline; the final event should carry the complete result. The modules array is the primary output of the entire pipeline and must reach the frontend for adapter transformation, storage, and workbench display.
