Function: isPreSendError

isPreSendError(value): boolean

True when value is an SDK error that was thrown BEFORE anything was transmitted (error.phase === 'pre_send'): validation, symbol resolution, the signer, the wallet, a key provider. A write that failed this way cannot have been queued, so the failure never calls for "confirm before you retry". Every failure of an app-supplied callback that runs BEFORE the request leaves reaches you as an SDK error of this kind (SIGNING_FAILED, KEY_PROVIDER_FAILED, TOKEN_RESOLUTION_FAILED, the original error as cause), so an app never needs an error class of its own to tell "nothing was sent" apart.

Whether to offer Retry is classifyFailure(error).retryable, not this: a pre-send validation error is pre-send too, and repeating the same call fails the same way.

It also answers for a plain-object view of an SDK error ({ code, phase? }, see FailureView): the view's own phase, else the catalog's phase for its code (a core code or a DEX code). It is a plain boolean, not a type guard (a view is not a GSwapSDKError); use isGSwapError to narrow.
