agentfootprint/dist/semantics/coverage/search/compose.js

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

"use strict";
/**
 * search/compose — ONE call's coverage, composed by the library from the
 * tool's `search` declaration and the arguments the call ran with.
 *
 * Pattern: linear composition of small pure rules —
 *          door (what came back) → inEffect (each argument) → facets
 *          (`checked`) → gaps → complete → the reading the funnel files.
 * Role:    semantics/ layer, pure. Called by the dispatch funnel
 *          (`../../../core/agent/stages/searchCoverage.ts` · `buildSearchCoverage`) at
 *          every execute boundary, before `declareCoverage`.
 * Emits:   N/A (the funnel emits, from the reading).
 *
 * ## Composition can only under-claim — relative to a TRUE declaration
 *
 * A declaration that misdescribes the query (an undeclared qualifier, a wrong
 * `complete`) is the trusted base, said out loud: the law holds relative to
 * it, never to the backend.
 *
 * A facet enters `checked` from exactly four places — a value the call sent, a
 * declared default composed as if sent, a declared fixed qualifier, the
 * declared (or sent) source — plus a host-filled identity filter (which only
 * narrows) and a result-declared period (which only narrows). Every
 * classified argument none of them covers is a bearing gap; a cap in effect,
 * a declared server cap, a page, a `partial` outcome is a completeness gap
 * unless the result says otherwise. So the composed scope is never wider than
 * what the declaration and the arguments say. A wrong declaration is the
 * trusted base, said out loud.
 *
 * ## Local and remote
 *
 * A `search` that arrived over MCP or from a `ToolProvider` composes the same
 * shape, marked `'remote'`, and is never `complete`: it establishes nothing.
