Storage-layout collision risk across upgrades

Jupiter's assessment for RD-F-142 — scored not_applicable on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

EVM proxy storage layout collision pattern does not apply to Solana programs. Solana program upgrades replace the entire BPF binary — account layout changes are managed at the Anchor IDL deserialization level, not via storage slots. The EVM-specific storage layout collision risk mechanism does not exist in the Solana substrate.
