Inherits: InfraredV1_10

Title: InfraredV2

pol-vnext upgrade. Inherits InfraredV1_10 without modifying its bytecode or the inherited storage layout and adds no new storage or selectors of its own. The vnext reward semantics are delivered entirely by the reworked RewardsLib: harvested WBERA is unwrapped, minted into iBERA, and iBERA is distributed directly to vaults and per-user harvest recipients in place of the legacy BGT/iBGT payout.

The harvest pipeline is not re-exposed with V2 selectors. The existing harvestBase, harvestVault, harvestOldVault, claimExternalVaultRewards, and externalVaultRewards selectors on InfraredV1_10 are made BGT+WBERA-aware by changes to RewardsLib alone: balance-delta logic measures both reward streams around vault.getReward(), and _wberaAndIbera() / _sweepWberaToReceivor() pull the vnext token addresses out of the calling Infrared contract via IInfrared(address(this)) (works because external library calls run via DELEGATECALL). A single keeper invocation covers both pre- and post-vnext-migration state — no V1/V2 selector split needed.

The reward-allocator role is not delegated. Infrared is the BeaconDeposit operator for its own validators and so is the implicit allocator via vnext’s operator-fallback path; no setValRewardAllocator passthrough is needed.

Booster-slice incentives (post-fork) flow to us passively via the Phase-2 LST integration: Berachain’s BGTIncentiveFeeCollector pays WBERA to every registered LSTStakerVault (ours included, once InfraredBeraAdapter is deployed and registered), and the adapter converts that WBERA to iBERA shares automatically. This contract does not run the auction itself.

Event-unit warning (legacy V1_10 events seen post-fork):

  • BaseHarvested(_sender, _bgtAmt) — the _bgtAmt slot is now BGT redeemed + WBERA swept; post-fork it carries the WBERA-as-native-BERA total only.
  • VaultHarvested(_sender, _asset, _vault, _bgtAmt) — the _bgtAmt slot is BGT delta + iBERA shares minted; post-fork it is iBERA shares only. Off-chain consumers reading this slot as “BGT amount” will be misled in unit but not in semantics (both quantities are denominated in BERA-equivalent reward).
  • ExternalVaultClaimed(user, asset, vault, bgtAmt) — same treatment as VaultHarvested. No new events are emitted from this contract for those legacy paths; reading the new vnext units off the existing _bgtAmt field is the deliberate trade-off for keeping InfraredV1_10 (a live contract) untouched.
