Kusama Inflation Parameters for Asset Hub Migration
Root (signal now, enact-ready for post-migration)

Summary:

This referendum pre-commits the post-Asset Hub staking inflation settings: keep 10% annual inflation and 75% ideal stake, and turn off the parachain-slot adjustments by setting “UseAuctionsSlots = false”. It contains a short on-chain remark stating that this is a pre-migration signal whose parameters will apply after the migration (and the canary community can revisit them afterward).

Why a vote if numbers don’t change?
Because the execution path changes after the Asset Hub migration. The auctions-dependent branch becomes irrelevant; without an explicit update, the chain could fall back to behavior not explicitly approved for post-AH. This proposal:

• Disables the auctions path by setting (UseAuctionSlots = false)
• Locks in the same headline numbers (10%, 75%) under the right path for AH.
• Voting now blesses the exact post-AH settings (10%, 75%), reduces ambiguity for operators/stakers, and records intent on-chain (remark).
• Signals now (via an on-chain remark) to reduce ambiguity for operators and stakers, and commits to re-evaluate the model after migration.

Why 10% and 75% now?
We’re prioritizing stability through the migration: keeping incentives familiar for validators/nominators and maintaining predictable Treasury dynamics. Changing rates today adds unnecessary risk; we’ll reassess after AH with live data (including options like alternative reward curves or gradual issuance schedules, or decreased inflation …. etc)

What exactly changes on chain?
A batched Root call that:
1- system.remark(...) – documents scope: post-AH signal, no immediate change, revisit after migration.
2- sets Inflation::UseAuctionSlots = false
3- sets Inflation::MaxInflation = Perbill(100_000_000) (10%) & IdealStake remains 75% as is.
