agentfootprint/dist/recorders/core/EmitBridge.js

The explainable agent framework — backtrack a wrong answer to the exact context that caused it (evidence, not guesses). Built on footprintjs.

"use strict";
/**
 * EmitBridge — forwards footprintjs emits whose name starts with a given
 * prefix to the EventDispatcher, enriched with EventMeta.
 *
 * Pattern: Adapter (GoF) + Pipes & Filters (Hohpe & Woolf, 2003).
 * Role:    Single reusable translation layer for every "pass-through"
 *          prefix recorder (StreamRecorder, AgentRecorder, and any
 *          future domain whose events are emitted via typedEmit()).
 * Emits:   Any event whose name matches `prefix` — type derived from the
 *          emit name and validated by the consumer's EventMap subscription.
