Deprecated contracts still holding value

Concrete's assessment for RD-F-166 — scored green on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

V1 to V2 migration was an in-place proxy upgrade, not a parallel deployment leaving V1 contracts independently holding user funds. Data cache coverage_flags.has_legacy_v1: false. No separate V1 protocol slug exists on DefiLlama. The V1 bytecode (superseded) is retired behind the EIP-1967 proxy; it is not independently callable. No deprecated contract with >$100K material TVL identified.
