1218.0.0

@metamask/perps-controller 15.0.0

Added

• Add Lighter as a perps venue (initial implementation, disabled by default) (#9889, #10015)
  • BREAKING: PerpsProviderType gains 'lighter'. Consumers with exhaustive provider switches must handle the new value. Enablement requires client opt-in: providerCredentials.lighter.enabled, or the perpsLighterProviderEnabled remote feature flag combined with a client-supplied providerCredentials.lighter.signerBridge (without a bridge the provider is read-only). Lighter follows the global network toggle on both testnet and mainnet (reads and writes).
  • The client-supplied signer bridge owns venue-key creation and persistence; Core never derives or receives the venue-key seed/private key. Lighter deposits are not advertised until the provider can build the required approval plus bridge-deposit call.
  • New Lighter types/constants exports, KeyringController:signPersonalMessage in the allowed messenger actions (type-only), and durable-settlement surfacing on the controller: getPendingManualRecoveries, getRecoveredDispatches, acknowledgeRecoveredDispatch actions with PerpsPendingManualRecovery / PerpsRecoveredDispatch exported types and OrderResult.partialState.
  • LiquidationPriceParams and MaintenanceMarginParams gain an optional providerId, and getMaxLeverage accepts the same optional route, so aggregated calculations use the provider that owns the market or position.

Fixed

• Preserve accepted HyperLiquid Scale orders when part of a batch is rejected (#9989)
