Note

Medium Risk
Changes Across quote construction and gas/fee normalization for post-quote predictWithdraw flows, including new error paths and gas-fee-token re-quoting behavior that could affect quoting correctness and strategy selection.

Overview
Adds Across quote support for post-quote predictWithdraw flows, switching these requests to exactInput, sending no destination actions, and optionally passing refundAddress through to Across.

Extends quote normalization to combine the original (pre-Across) transaction gas/fees into sourceNetwork and gas limits for post-quote requests, and updates gas-station accounting accordingly.

Introduces special-case handling for EIP-7702 authorization lists: allow source-chain authorization lists only for post-quote predictWithdraw quotes with empty Across actions, while continuing to reject authorization lists elsewhere. Also expands the re-quote “reserve source token for gas-fee-token” flow to cover post-quote withdraws, with stricter failures instead of falling back to phase-1 in unsafe cases.
