Greptile Summary

Records completion of the Phase 0 functional gate without extending the project’s evidence claims beyond E1.

• Marks G0 and Phase 0 as passed and records the merged implementation commit and successful CI run.
• Activates Phase 1 and directs work toward freezing the public evaluation before retrieval tuning.

Confidence Score: 5/5

The documentation-only change appears safe to merge, with no concrete correctness or security issues identified.

The updated roadmap consistently advances from the completed functional gate to the evaluation-freeze phase and preserves the stated E1 limitation and freeze-before-tuning order.
