// Package errors provides internal-facing error types for use in Boulder. Many
// of these are transformed directly into Problem Details documents by the WFE.
// Some, like NotFound, may be handled internally. We avoid using Problem
// Details documents as part of our internal error system to avoid layering
// confusions.
//
// These errors are specifically for use in errors that cross RPC boundaries.
// An error type that does not need to be passed through an RPC can use a plain
// Go type locally. Our gRPC code is aware of these error types and will
// serialize and deserialize them automatically.
