Stale-approval exposure on deprecated router

EigenLayer'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 #

No deprecated router identified in current contract surface. EigenLayer uses transparent upgradeable proxies; user approvals to the proxies persist through implementation upgrades by design (not a deprecated-router problem). No approval-to-deprecated-contract pattern identified. Gap: no automated allowance scan performed.
