Note

Medium Risk
Touches trading readiness/signing flows and the rewards discount integration (including a DI signature change), which could affect when users are prompted to sign and how fees/discounts are computed. Most changes are additive guards/logging but in a user-critical trading path.

Overview
Improves HyperLiquid unified-account migration behavior by deferring signing-backed setup for hardware wallets across more abstraction modes, and expanding hardware keyring detection (Ledger/Trezor/OneKey/Lattice/QR) to reduce repeated signing prompts while browsing.

Hardens error classification by adding isKeyringLockedError (walks cause chain) and using it to treat SDK-wrapped keyring-lock failures as retryable for unified-account setup, builder-fee approval, and referral setup.

Updates rewards discount resolution to pass the perps builder base fee (in bips) into getPerpsDiscountForAccount, and treats null (unhydrated subscription state) as “unavailable” rather than a definitive no-discount result. Adds additional error logging for failed cancel/close/TP-SL operations (including batch failure summaries).
