Summary

As the Nolus network adopts a semi-permissioned blockchain model, contract migrations require governance approval. The Nolus money market architecture is divided into a platform core, shared by every integrated chain, and a protocol core with contract instances tailored to each integrated chain.

This proposal migrates the protocol contracts of the Solana Metis USDC protocol (SOLANA-METIS-USDC) on the Nolus Pirin mainnet to v0.9.1 — Leaser, Lease, LPP, Oracle, Profit, Reserve, and the Remote Lease controller — using the codes pinned by the preceding proposal. The platform contracts and the OSMOSIS-OSMOSIS-USDC_NOBLE protocol are untouched. The release:

• Restores in-place upgrades for the Leaser and the Lease. Both contracts kept the v0.9.0 cut-over posture of rejecting every migration; they now accept same-storage migrations again, and the live leases are moved to the new Lease code in the same transaction.
• Corrects the NLS market symbol on Solana. The protocol is rebuilt from a topology carrying the Solray program id, so the Oracle resolves the NLS dex_symbol to its Solray mirror mint B9Vhg6XrNswZvLdKgpKhZ9Fj9yV7j2RxQKUaq5fmuphv instead of the IBC hash. With the NLS/USDC pool live on Solana, the price feeders can now publish an NLS price for this protocol.
• Rotates the Profit settlement address. The Profit contract gains a governance-driven change_settlement sudo; this proposal uses it to move the settlement of the protocol's accrued profit from the Treasury contract to nolus1luvaejqplajhq33xpn42ffsy6558fzg4dvkqnz.
