Original prompt

Phase 3: Epic Validation & Closure (Days 22-28)

This epic focuses on validating that all RC1 and RC2 epics meet their completion criteria, closing them out, and ensuring the project is ready for final RC3 work.

Objective

Systematically validate and close all "done" but still-open epics, ensuring all acceptance criteria are met and dependencies are resolved.

Background

Multiple epics are marked with the "done" label but remain open. This phase ensures rigorous validation before closure and identifies any remaining gaps.
