Summary

Execute the previously whitelisted Utility.batchAll call via the Whitelisted Caller track to atomically authorize the v7200 runtime upgrade and update the collator reward to 2 BRIDGE. This proposal must follow successful enactment of the prior Fellowship whitelist referendum.

Dispatch call

• Outer call: Whitelist.dispatchWhitelistedCall(callHash, callEncodedLen, callWeightWitness) (pallet index 83, call index 2)
• Parameters:
  • callHash: 0xb120ce0c342d8f84b085aa9d9ac1279f7b8ee6cf7da9197c28db391e401b5c44
  • callEncodedLen: 57
  • callWeightWitness: weight of the batched call — fill from polkadot.js when constructing
• Preimage to register (via Preimage.notePreimage): 0x0402088800090a4f794f7e0da8b2a7385ccaf288d7cafc569eb5a60289729050b6d592bc1692485d0000204aa9d10100000000000000000000
• Preimage decoded:

  Utility.batchAll([
    System.authorizeUpgrade(0x0a4f794f7e0da8b2a7385ccaf288d7cafc569eb5a60289729050b6d592bc1692),
    CollatorManager.setCollatorReward(2_000_000_000_000)  // 2 BRIDGE
  ])

Verification steps for voters

1. Confirm a successful Fellowship whitelist referendum exists for call hash 0xb120ce0c342d8f84b085aa9d9ac1279f7b8ee6cf7da9197c28db391e401b5c44.
2. Confirm the preimage is registered on-chain and decodes to Utility.batchAll([System.authorizeUpgrade(…), CollatorManager.setCollatorReward(2_000_000_000_000)]).
3. Verify the keccak-256 of nexus_runtime-v7200.compact.compressed.wasm equals 0x0a4f794f…c1692.

Enactment plan

1. Register the preimage via Preimage.notePreimage(0x0402…0000) if not already on-chain.
2. This referendum passes on the Whitelisted Caller track, atomically dispatching System.authorizeUpgrade and CollatorManager.setCollatorReward in a single block.
3. Any account submits System.applyAuthorizedUpgrade(code) with the WASM blob to complete the runtime upgrade.
