Storage-layout collision risk across upgrades

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

Evidence summary #

7 total LBTC implementation upgrades since 2024. OZ V2 audit (Nov-Dec 2024) and OZ multipauser audit (Apr 2026) included LBTC in scope, suggesting OZ would have flagged storage-layout issues. No public storage collision report. However, full OZ upgrades-plugin validation across all 7 upgrade pairs was not confirmed from public sources.
