GM maintainer... I’d like to take this because upgradeability is a high-leverage foundation for protocol evolution. I’ll implement a UUPS-style proxy architecture (proxy + implementation) in truthbounty-contract, add strict upgrade authorization (admin/governance-only upgrade_to with require_auth()), and enforce storage-layout safety by keeping all state behind stable storage keys and adding explicit versioning/migration hooks. I’ll include upgrade scripts for deploying the proxy, initializing the implementation, and performing an upgrade, plus tests that deploy v1, write state, upgrade to v2, and verify storage is preserved and new logic works; the suite will also assert unauthorized upgrades fail and the upgrade path is deterministic.
