- snowbridge-pezpallet-* → pezsnowbridge-pezpallet-* (201 refs) - pallet/ directories → pezpallet/ (4 locations) - Fixed pezpallet.rs self-include recursion bug - Fixed sc-chain-spec hardcoded crate name in derive macro - Reverted .pezpallet_by_name() to .pallet_by_name() (subxt API) - Added BizinikiwiConfig type alias for zombienet tests - Deleted obsolete session state files Verified: pezsnowbridge-pezpallet-*, pezpallet-staking, pezpallet-staking-async, pezframe-benchmarking-cli all pass cargo check
