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

"use strict";
/**
 * messageApiReceipt — the one mint the two message-API charts share, and the
 * one place that says when a chart may not mint at all.
 *
 * Role:  Lens. One pure function over what a `call-llm` stage already holds.
 *        It reads no scope, emits nothing and commits nothing — the caller
 *        commits what it returns, under `conventions.ts` · `RECEIPT_KEY`.
 * Reads: its arguments.
 * Emits: N/A.
 *
 * WHY THIS FILE EXISTS. `buildMessageApiChart` and `buildAgentMessageApiChart`
 * are deliberate twins — the second is the first plus tools, a router and a
 * loop — and a mint written out in both is two chances to disagree about what
 * the model was handed on charts whose whole job is to be the same shape. The
 * arguments differ per chart (one has tools, one does not); the RULE does not,
 * and the rule is what lives here.
 *
 * THE RULE: NO RUN ID, NO RECEIPT. Every hash a receipt carries is salted with
 * the run id (`receipt.ts`, the third law) so a short system prompt or a
 * two-word turn cannot be fingerprinted across runs, and a receipt is committed
 * state that travels inside recordings. These two charts are exported BUILDERS
 * handed to an executor the caller owns — nothing in a stage's scope carries
 * that executor's run id — so the salt has to be supplied, and when it is not
 * this returns `undefined` rather than minting with an empty one. `servedAt`
 * then declares the absence (`no-receipt-on-chart`, cause
 * `'no-receipt-committed'`) and rebuilds the view exactly as it always did: a
 * Lens may omit, never deny.
