Euler V2's assessment for RD-F-168 — scored gray on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

Euler V2 has no deprecated routers. V1 is a separate deprecated deployment; V2 shares no contract surface with V1. Stale approval exposure to V1 contracts is an ops-history concern (Cat 5), not a V2 post-deploy hygiene finding.
