Summary

Execute the previously whitelisted Utility.batchAll call via the Whitelisted Caller track to atomically apply the v7300 runtime upgrade, set the BEEFY prover reward, and clear the invulnerables list. This proposal must follow successful enactment of the prior Fellowship whitelist referendum.

Dispatch call

Dispatches the whitelisted nexus-v7300 upgrade batch (previously approved by the Fellowship). The batch atomically:

1. Runtime upgrade — System.authorizeUpgrade(0x3aadd6f2bf73c8ed017da4ee3e09a47bcb6fee4ba2d8f4b471c785c3330a40c3) authorizes the nexus-v7300 WASM
2. BEEFY proof reward — BeefyConsensusProofs.setProofReward(100_000_000_000_000) — sets reward to 100 BRIDGE per proof
   3–7. Remove invulnerables — removes 5 accounts from CollatorSelection invulnerable set:
   • 0x2226f04c...396f
   • 0x28b6094895...814c
   • 0x3cec6973...9978
   • 0x5254bab9...6b5c
   • 0xd4b23d66...f429
3. GNOSIS consensus init — Ismp.create_consensus_client(...) initializes the GNOSIS light client state

Verification steps for voters

1. Confirm a successful Fellowship whitelist referendum exists for call hash 0xe1534720255d35912c2ca5458b87fdecef3e0ebdc592ab28357cc996c463d820.
2. Confirm the preimage is registered on-chain and decodes to the Utility.batchAll above.
3. Verify the keccak-256 of nexus_runtime-v7300.compact.compressed.wasm equals 0x3aadd6f2…0a40c3.

Enactment plan

1. Register the preimage via Preimage.notePreimage(0x04020c…0000) if not already on-chain.
2. This referendum passes on the Whitelisted Caller track, dispatching the batch atomically — runtime upgrade authorized, prover reward set to 100 BRIDGE, invulnerables cleared.
3. Any account submits System.applyAuthorizedUpgrade(code) with the WASM blob to complete the runtime upgrade.
