Module: Hitch::MCP::Internal::LocalDiagnosis

Defined in:
app/models/hitch/mcp/internal/local_diagnosis.rb

Overview

A client must learn nothing from a host failure; the developer who wrote it must learn everything. Those are two audiences and only the first is a threat, so in development and test the real exception goes to the local log. Callers' wire responses are unchanged, and production stays silent.
